EDIT

O NOTE

R’S

Our cityscapes and how we work, live and relax within both the buildings and the surrounding urban spaces are set to change beyond all recognition in the coming decade. One of the key drivers of this change will be the continuing digital revolution, and the evolution of Artificial Intelligence (AI), through what many are calling the 'smart technologies’. Building façades play a very important role in making cities smarter. A sophisticated façade allows an architect to create an aesthetically beautiful design using both the physical form and with the additional medium of light. A building may change colour throughout the day and night, or by playing with the perspectives, they would be able to create stunning visual illusions and merge the structure seamlessly into its environment. Façades can also act as a responsive, communicative and an adaptive medium to make buildings more environmentally effective. A prudent understanding of the dynamics of building performance is necessary for this. This edition focuses on an important aspect of modern, sustainable, and landmark buildings the façade lighting - and the pertinent smarter technologies which can be integrated into façade lighting in order to keep pace with the changes and commercial requirements. We have rolled-out our newly designed, improved website www.wfmmedia. com, which will help you to keep up to date with all that is going on in the façade and fenestration industry and novel designs. We hope that this site will be informative to you and help to interact with us in a much easier way. We look forward to making additions and improvements to the site and welcome your feedback. We would be pleased to receive your comments and glad to upload relevant articles, blogs and projects. With this issue, our magazine, Window and Facade, completes five years. Purely in terms of age, these are still early days. However, we have displayed maturity throughout and have, over the years, presented to you a wide range of information-packed content. We too have been learning on our way as fast-paced developments in domestic and global industries throw up new technologies and materials every day. We owe sincere gratitude to all the contributors and well wishers. Thanks, as always, for your support and encouragement.

Façade Lighting

Façade and Light

ight has always played an important role in building design and construction. A building cannot be functional without access to light. Lighting design is mainly characterised in two categories, natural and artificial lighting. Both lighting possibilities have an acute effect on indoors and outdoors during different times of a day through the fenestration of the building. The effect is defined in terms of views exchange, impact on the environment, the health of occupants, etc. There are various tools such as Grasshopper in Rhino, IES, Sefaira, etc. that help to understand these effects before the actual construction of the building. Therefore, a building's façade design plays a very important role in the indooroutdoor relationship of lighting. DAYTIME The key to façade design is the relation between the outside sunlight and its interaction with façade to allow the daylight to enter inside the building to facilitate various functions. Not only does this make the building more energy-efficient, but it is also healthy for the occupants of the building. As per various research, daylight is known for regulating our circadian rhythm

WFM | JUL - AUG 2019

and keeping our mental health in check. The exposure to light has a direct relation with the impact on the eyes as well. Therefore, an appropriate amount of daylighting should be incorporated during façade design which meets the melanopic lux level requirement (200 melanopic lux). Lux levels are always calculated at 1.2m from the finished floor facing the vertical plane being measured. The interior space should be checked to meet all the light temperature and colour rendering index while designing the façade and installing the light. The design of optimal façade with the incorporation of daylight entering the building, not only regulates the body-clock of occupants and decreases the energy requirement but also gives access to outdoor views to the occupants and increases their productivity. NIGHT-TIME Interaction of indoor to outdoor lighting is not just restricted to daytime but has a major significance during night-time as well. During the night, the indoor light is scattered outside around the building, creating a light halo around a building through its fenestrations. This tends to create glare and light trespassing. This type of light is called the waste

light, it does not contribute towards night-time safety, utility or security, but consumes energy and disturbs the flora and fauna. The lighting requirement and directions should meet the outdoor lighting zone requirements to avoid light pollution during the night. This can be done by meeting the required consideration during the design of the façade and choice of lights. Choice of lights include the design of luminaire, intensity, colour temperature, colour rendering index for all indoor space, outdoor space and façade itself. Various types of light filtering glasses can be used to prevent the disturbance in the path of migrating birds and the growth of plants. Technology is moving at a very high speed and kinetic façade (dynamic façade) is making it easier to achieve the day-time and night-time lighting requirements without compromising on aesthetics and energy-efficiency. The support of tools such as Ladybug, Diva, Honeybee with Arduino helps in the overall optimal design of façade at an early design stage. A building façade is treated and tested properly at the design stage to meet the predicted EUI (Energy Use Intensity) of the project and make it healthy for occupants at the same time.

Case Study

Children’s Hospital of Richmond CHoR: Panels

n collaboration with Zahner Metals, HKS Mid Atlantic Design (MAD LAB) developed a screen system for the Children’s Hospital of Richmond (CHoR). A parametric model utilising Grasshopper for Rhinoceros 3D was created to explore the relationship between various hole sizes and the spacing

between them, considering variables such as air filtration, dye punch size, light filtration and aesthetic preference. BIOPHILIA AND LIGHT: In keeping with the metaphorical references to nature, the concept for screen and light quality within

the parking garage came from the dappled light effect much like sunlight filtered through tree canopies in a forest. Extrapolating this information from the concept, a pattern was developed based on the camouflage algorithm used by the military to mimic foliage patterns found in nature.

Children Hospital, Delhi

he Children Hospital in Delhi was a big challenge for maintaining a healthy and energy efficient hospital for children. The façade design concept derives from the superhero cape and signifies the protective nature. It was categorically distributed with the coloured solar panels in place of glazing (LOF solar cells) for generating the energy through façade and yet keeping it interactive and colourful. The façade design went beyond the aesthetics to meet the melanopic lux levels for all the patient rooms to increase the healing and synchronisation of circadian

rhythm. The dynamic feature of façade at night decreased the light pollution by decreasing the intensity of light halo around the building.

Case Study

Kachumbla, Uganda

achumbla’s maternity unit is yet another example of not letting go of the true sense of architecture, design and needs when it comes to façade. The project is the best example of “For the people, by the people”. It is a passively designed maternity unit in Uganda in which windows are placed strategically along with terra cotta screens on façade. The design not only provided for thermal comfort, but also for natural light and improved healing. The predominant

building material, interlocking soilstabilised blocks, were handmade on-site using locally arising Murrum mixed with cement in a brick press, which reduced both cost and the need for power tools. HKS partnered with Wales-based Charity Engineers for Overseas Development and Clyfe Building Skills to design, fund and build the new maternity unit. The jaali façade extends the play of light to give the connection with outdoors and provide thermal comfort in the heat of the place.

for Light

he night-time economy is increasingly being seen as revitalisers of a city’s economic and tourism growth. This has led to the setting up of ‘night czars’ – or city planning councils to promote nightlife in urban centers, together making a strong case for extending a building’s iconicity after dark. And while it serves no other functional purposes, façade lighting does serve as an extremely useful marketing tool that seeks to engage with the public even after the facility is closed. Just as cardinal orientation (of glazing) is crucial to the designing of lighting

WFM | JUL - AUG 2019

in interior spaces and how much to limit or intensify the amount of artificial lighting, the orientation of building to views and angles of view is crucial to the design of the façade lighting. It not only dictates how to maximise on and address prominent views - which elements to emphasise and which to neglect, but how a luminaire must be positioned to avoid glare and light trespass, how a detail must be integrated to avoid seeing the light source yet see the effect of light. Key location plans usually serve as valuable inputs to the façade lighting design indicating the direction of vehicular movement,

adjoining high-speed vehicular arteries and neighbourhood streets, and the urban context. In the following section, we describe the façade lighting – design, process and outcome for two very distinct projects, but are unified in their approach towards lighting. For Intersekt and for the Neelkanth Sarovar Premiere – with two radically different façade designs, in two places thousands of kilometers apart from each other, in two very different cultural and urban contexts, they stand testimony to our belief that the language of light knows no boundaries!

Case Study

Intersekt, New Delhi, India

Intersekt, New Delhi, India – Subtle warm lighting

wo identical buildings existed on the site that served as a warehouse for the brand’s vast collection of tiles. The new development was to create an experience center on two floors with the corporate headquarters on top. Keeping the original structure intact, the architect visualised a metamorphosis of the façade to depict the weathering of rocks. The result is a dynamic sculptural formation with jagged edges and acute angles. To achieve this a second structural framework was built, with its own separate foundation and clad with large format tiles and secured to the original structure. As lighting designers on the project, we came on board, when the interior was already completed, lights installed and ready to be opened when the client decided that something was not quite right! The lighting conceptualisation, wiring for the automation, procurement of fixtures for 30,000 sq ft of retail space was reinitiated and redone. At the same time, the façade execution was in progress.

WFM | JUL - AUG 2019

The night time rendering of the façade was modified and the lighting intent adapted to better underline the façade concept. In place of two continuous illuminated bands in the façade, discreet warm lighting was introduced in each protrusion seeking to emphasize the jaggedness of the façade. The detail

was tweaked to accommodate a warm 2200K homogeneous, encapsulated LED profile for a soft accent contrasting against the sharp material form. The corner of the building is highlighted using screened projectors with precise beams to avoid glare to users or passerby’s while the louvered crown is underscored using linear grazers.

The night-time image of the building

WFM | JUL - AUG 2019

Case Study project’s lighting was conceived, developed, executed and commissioned over just 3 visits to site but with innumerable emails, web calls, video meetings, drawings and documents. The façade lighting intent however, remained practically unchanged from day one. It sought to simply integrate with the architecture and highlight elements, relief, surfaces and material. The entire scheme was almost completely realised by the use of a single luminaire type – the linear LED profile. These were used to glow the edges of vertical bands at the base; placed with intervals of half a metre to emphasize horizontal bands on a dead wall façade; uplight a 100 mm x 100 niche on the guestroom windows façade and so on. The controls for these profiles were also intelligently combined and drivers located together at a few easily accessible, strategic locations. The versatility of a single light source relies heavily on the creativity of the designer and how he can imagine applying the same fixture in multiple situations, applications and ways. A typical façade lighting project involves the use of a minimum of 3-4 types of luminaires and these may be bought out from different vendors / manufacturers to optimise the cost-value proposition or simply the unavailability of all types of suitable equipment with one manufacturer. By limiting the use to one major type of luminaire, there was better control on the CCT (Corelated Colour Temperature) and 3000K everywhere on the façade seems the same. It helped avoid a potential problem that the same colour temperature tends to vary between different manufacturers and even

WFM | JUL - AUG 2019

between different luminaire types of the same manufacturer simply because different brand LED chips are applied. The result is a better ‘put-together’ façade lighting which may not have been achievable even by investing more in good quality equipment if they came from different brands. Besides the above, a single element, in the brand’s signature blue, appears in the façade in the form of a blue wash on a vertical band of the façade – everything else is in a warm 3000K. Blue is also a great choice for façade lighting simply because it seems to disappear and blend into the night sky ubiquitously. Together tones of white and blue have proven time and again to be successful combinations for façade lighting and once again, the Neelkanth Sarovar Premiere stands in testimony to this winning theory.

Façade Lighting

Adding Value to

Façade Efficiency & Aesthetics

uilding façade is one of the most vital pieces of design, which refers to the side, normally the front side of a building structure. It provides a great opportunity for designers and architects to play around and display their design skills and artistic talent. But a façade is more than just for show to the public. The design of façades is highly complex, at the same

time extremely important in determining the success of a building. The façade does not only integrate with architectural context, but also play a key role in the building performance. In theory, a façade designer has to strike a balance between visual and thermal performance of the façade, which plays an important role in energy consumption and thermal comfort of the occupants inside the building.

The right façade lighting is not about intensity, but functionality

WFM | JUL - AUG 2019

Façades are not only designed for their aesthetic reasons, but there are also several factors that need consideration such as types of materials and their durability, ease of installation and maintenance, cost factor, resistance to corrosion and other chemicals are some of the common considerations that goes into an effective façade design and implementation. That being said, the important aspect of the façade is that it adds value to

Façade Lighting

Façade lighting is not merely for visibility, rather it signals the emotion of the building

both the efficiency and aesthetic of the façade is the façade lighting. In high rise buildings, façades are of significance mainly because they impact the thermal comfort temperature of the insides. “Technically speaking, the light efficient façade or

building envelope that adapts to environmental light conditions - dates back to the first window. But the contemporary idea of the façade has only been around for a few short decades. Energyproducing algae face, lightresponsive façades, smog-eating

Façade patterns, that under the right lighting, would bring out the artistic outlook of the building

façades, operable skin façades, etc. are some of the innovative façades that are gaining prominence. These façades become particularly important when a large part of the building is covered by it,” says Juzer Kothari, Managing Director, Conserve Consultants Pvt Ltd, a specialist in Building Sustainability. FAÇADE LIGHTING: In architecture, the façade of the building is the most important area for the architect to showcase his artistic impression and bring out the concept of the building, as it sets the tone for the rest of the building. Façade lighting, which is also part of the façade design, is not only to localise the building and provide security, but also plays a key role in expressing the architectural and artistic impression of the building. The lighting draws attention to the textures, colours and forms of space, helping the architect to achieve the true purpose of his or her design. As it's been said, vision is the single most important sense through which we enjoy architecture, and lighting

WFM | JUL - AUG 2019

Façade Lighting enhances the way we perceive architecture even more. In recent years, façade design has been the signature of famous architect firms, who want to leave a mark through their unconventional façade design that stands out, and lighting is one such aspect that is helping them to bring out their uniqueness. A good façade lighting should have the following key aspects such as: 1. Aesthetic 2. Function 3. Efficiency Aesthetic: As the whole concept of façade lighting is to add value to the design, it is only evident that aesthetic forms a major aspect of façade lighting. The aesthetics is where designers and architects focus on the emotional impact that it will have on the occupants. It also determines how the occupants feel when they walk around the space. Aesthetics have become an important crowd-pulling aspect for retail locations, where the consumers are owed through the design and lighting of the façade. Function: Though aesthetic comes as a natural requirement of façade lighting, the less known aspect of its function is the most important factor in the façade lighting. Lighting has mixed-use and we all want it to look a certain way, but also want to ensure that it serves its most important purpose, in this case, the illumination of the building and create visibility. Research studies suggest that lighting has a high index of disrupting the thermal comfort of the occupants. If it goes higher than the expected level, or lower than it, it creates a strain on visibility, causing migraine among the occupants. Hence, the optimum façade lighting should ensure proper illumination that makes occupants feel soothing to see the

WFM | JUL - AUG 2019

entire building. They should also bring out the difference in design or structure in the façade. Efficiency: In the age of green and sustainable buildings, façades have gained more prominence in ensuring the sustainability index of the entire building. One aspect is to create a breathtaking façade lighting, entirely another one is to create a breathtaking layout that is also incredibly energy efficient. This can be done assuring that the majority of the light is reaching its target and there is less wastage of light. Reducing the amount of wasted light will make the façade more efficient. “GREEN” FAÇADE LIGHTING It was soon enough, that we saw that façade design has transformed from being exterior membrane to an intelligent skin that interacts with the building interiors and also the outer public spaces using embedded LEDs and customer designed software, most of all powered completely by solar energy. These façades show us a glimpse of what is the extended

role of façades in the future. From being a protective layer of the building to the reflection of its character. GreenPix Media Wall is a groundbreaking concept in façade lighting, that integrates sustainability and digital technology, and forms a communication channel to the audience. It features the largest colour light-emitting diode (LED) of 2292 LEDs to form the illuminated curtain wall, comprising an approximately 2000 Sq m of interactive skin and are integrated with photovoltaic systems for power generation in a sustainable way. The façade wall is over 60m, which is the largest in the world, and covers of 10-storey building. The GreenPix Media Wall stands as a testament of how façade lighting stands at the juncture of sustainability and aesthetic by striking a great balance between the two. The wall by itself has a self-sustaining energy life-cycle, harvesting enough sunlight for its operation, making it one of the most energy-efficient LED displays in the world.

The health care facility has 10 operation theatres and 100 critical care beds, making it one of the largest hospitals in India. Being an ambitious project as it is, the façade in the project plays an important role in ensuring that the hospital’s vision and its operational efficiency are in balance with each other. The façade design by MGM is inspired to create soothing illumination from the exterior. With the support of the lighting consultant, various simulations were done to arrive at the perfect hue and saturation required to create a required illumination. MGM stands as one of the very good examples of how façade design and lighting complement towards each other, and together they uplift the outlook of the building.

Façade Lighting

Architecture in the Light of the ‘DARK’

couple of weeks ago, from my visit to the world’s most romantic city - Paris, witnessing the stunning show of light and colour, I was awestruck by the Saint Chapelle’s beauty, its radiant light, striking colours and juxtaposition of natural light on the stained glass windows. It is one of the finest examples of an architectural marvel clothed in daylight bringing a sense of peace and serenity. Light provides both intellectual as well as physical form to our world. As an architect, I have been unable to ignore these rather obvious conditions. Physical movement combined with a relationship to light promotes our well-being - both physical and intellectual. Natural light not only plays on the comfort, health and mood of man, in architecture, but this is also an integral part of the design of a building, bringing an added value. However, in a 24-hour day, it is difficult to meet all the lighting

needs of a building, which is why artificial light is used. It becomes essential that particular tasks are done indoors, and some evening activities outdoors. Hence, lighting solutions are supported for natural light during the day and has utilitarian and specific functions at night. One could say that the design of a good lighting designer is based first and foremost on the proper use of natural light followed by right implementation and usage of artificial light whereby illumination of a building façade determines a very significant role in marking an identity of the building and the local environment. Frequently, the night identity is different and independent from the day identity. The night identity gives a new meaning and images to the buildings and lifts the

profile of the vicinity. Façade lighting shapes the image of a townscape, attracts attention and lures in large numbers of tourists. This boosts revenues and enhances prestige. It also gives investors an economic incentive to gentrify real estate and upgrade property usage, thus making it economically more attractive. Façade lighting creates added cultural value.

of any important civic building, hotels, restaurants, railway stations, old heritage monuments, stadiums, etc., making a statement by itself that speaks a lot about the city to its visitors and citizens, reflecting the city’s values and instilling a sense of pride within the citizens. It can actually change the way we look at the buildings. In principle, we can recognise in the night urban scene, several kinds of lighting applications and their sources right from public illumination for public areas, object illumination, noticing the architecture of the building, advertisement, illumination of window exhibition in the historic center, and temporary sources, etc. In a world highly concerned

about carbon emissions, global warming, sustainable design and light pollution, the planned use of artificial light on building envelopes has become of paramount importance and strategy to improve energy efficiency by minimising lighting, introduction of innovative, advanced lighting systems that can considerably reduce building’s electricity consumption and have significantly improved the quality of light indoors and in the outdoor environment. With the increase in complexity of client needs and new roles and expectations resulting from technological developments, being lighting experts and designers, it becomes a role more

important for us to consider technological as well as aesthetic aspects and critically integrate this sensitive interrelationship into a lighting concept that can transform an anonymous building to an appreciated landmark. Operators, inhabitants and the town itself reap equal benefit from this in the long term. This is achieved in two ways - either by emphasising architecture in a traditional manner or offering freedom of expression and style using contemporary techniques, that provides ease and flexibility to control our environment, create different scenes to suit the requirement of space. Traditional architectural lighting solutions place emphasis on the architecture, materials and the lighting effect sought after by the architect and building owner. Architecture is illuminated without altering the character of a building. Individual façade elements are accentuated and the natural structures of the façade are emphasised. Bright, vertical surfaces produce a greater sense of security and assist with orientation. On the other hand, contemporary lighting transforms architecture by using light to shape it rather than simply accentuating the façade elements. Light patterns, structures and colours inject fresh character into plain, unpretentious architecture at night. Neutral objectivity is replaced by an emotionally perceived experience. Many architects want to deliberately give their structures a completely fresh night-time look. This sort of lighting replaces classic accenting and plays with bold colours. Creative lighting patterns and structures breathe new personality into neutral buildings. They arouse attention and shape a townscape. Creative lighting elements invite the onlooker to contemplate and linger and provide an interestingly varied atmosphere. When

Façade Lighting integrated well with traditional lighting, contemporary lighting techniques not only help to create a WOW factor, they also add drama as well as interest to a bland space. Going ahead, as we see a paradigm shift in technology from it being just functional till a couple of years ago and now embedded in our daily lives, integrated into our lifestyles and our DNAs, lighting too has seen transformations from an incandescent lamp to CFL to LEDs and now smart lighting systems. Today we can create a world where, we can connect every light point to the internet, can take control over our environment, customise our space as per our choice and connect to that space, providing information to enhance our experience and effectiveness. Not to forget here, seamless integration of both the above-mentioned styles play a major role when we move from conventional LED systems to smart lighting systems, hence striking a balance between both. LED technologies and lighting control systems are making lighting ever more versatile. Media content can now be played back onto light fields. This imparts information to the onlooker that goes beyond the appearance of the architecture. Communicative lighting concepts are deployed primarily in outdoor areas and are used as prestige projects for

towns, brands and investors. It is done by creating images, videos, animations or extravagant colour patterns, transforming façades into dramas of light, staged in corporate colours, leaving a highly memorable brand identity that is recognisable even from afar. Times Square in New York, Piccadilly Circus in London and the Ginza District in Tokyo are perfect examples of where the character of the area, as well as the townscape, is based on lighting, however many our cities are becoming over-illuminated by back-lit signs, media screens and street lighting. Many contemporary buildings are made of glass and become like giant light fittings when lit up. If we fill every square inch of the visual landscape with light, then it becomes a very uniform and very dull, flat and uninviting solution.’ Getting just the right amount of light is the challenge because too much light can lead to light pollution, a term that is being used now to describe some city landscapes. Beautifully-lit buildings light up the surroundings too therefore, the lighting solutions used need to be sustainable, save resources and prevent unnecessary light pollution. Hence, it is necessary to investigate the effects of stray light in the design of the large illuminated area, particularly advertising with the amount and direction of the reflected light that can definitely determine limits for luminance in a specific proposal.

Façade Lighting

Responsive, Communicative & Adaptive Façade Lighting

e are in a busy world - a zone where days and nights are intervened together through global economics and dynamic time zones. Work and recreation are no longer time-bound, extending through long nights. Buildings and lifestyles are changing rapidly keeping in tune with globalisation in an era of intense competition and faster time-cycles for every activity. Architecture and buildings are rapidly evolving to keep pace with change - from smarter technologies, cleaner environment to energy-efficient

and dynamically responsive buildings - and are no longer static mute spectators but are active and participative. Artificial intelligence and IoT have added new dimensions to an otherwise unanimated space. Façade design and façade lighting industry is also rapidly evolving leaps and bounds. Apart from being “simply beautiful”, it has now moved on to be responsive communicative and adaptive. From simple modules of analysing glare due to sunlight, it has moved further to assimilate climatic data, responds to changes in weather, etc. Lighting too is communicative and creative. It not only adds

magic to the building but also builds identity not only to the edifice it represents, but also creates a story line to a cityscape. From static to dynamic, from muted to being a statement, both façade and façade lighting became primary, “identity makers”. Façade also can be a communicative tool as pioneered from the famous “Times Square” of New York, where lights & façades are also informative and communicative. In short, façades are also a great advertising tool. The changes in the industry are rapid and I’m sure that the emerging possibilities will be mind-blowing.

after dark. With façade lighting, building owners can choose to highlight entrances, pillars and specific architectural features. The interplay of light and shadow is used intelligently to prevent a monotone appearance of the external surface of a building. Preserving a building’s integrity and functionality is essential though. Hence, it is imperative

Façade lighting highlights the subtle features of a building

that the façade lighting solution is designed to fit into the overall design aesthetic, rather than dictating the existing architectural form. Digital technology is rapidly increasing the dynamic interaction between building, its users and the surrounding environment. Developments in the lighting technology are empowering architects and designers to create dynamic designs integrating lighting and media displays on façades. Media façade lighting is layers of individually controllable lights attached or woven into the building façade that turns into a gigantic screen displaying text, graphics and animations. Seamless integration of these layers on existing structures pose challenges for architects and designers. Aspects such as materials and texture of the external surface, sizes, elevation, spatial relationships of various surfaces impact the design of such media layers. With brands creating new and innovative ways to connect with their audience, displaying images or videos on building façades has become an eye-catching medium. Media façade lighting offers numerous possibilities to communicate with viewers and reinforce the emotional connect with a brand. Due to their size, colour and appeal, media façade installations stand out as

individuals in the urban nightspace. Creative media displays are driven by narrative content and complementing imagery. Heritage buildings are turned into fascinating edifices with more architecturally oriented media façades that draw tourists’ attention. While abstract dynamic lighting patterns provide urban orientation. Advance media façade solutions offer complete integration of dynamic media applications into sleek architectural panels on the exterior of a building. This provides innovative modes for displays on varied surfaces that don’t stand out as conventional bulky equipments. This rather highlights the subtle features of a building. Another technological development offers an architectural mesh that clads the external surface of a building like an outer skin and doubles up as a large-scale media display screen. Simultaneously, it remains transparent from the inside without blocking the view of its occupants. When the media screens are not in use, the LED profiles appear nearly invisible against the transparent mesh façade. While the hybrid media display screen is another

innovative lighting solution that allows projecting depths and textures through multi-layered applications. It provides a layer for simple media displays directly on the façade, and another layer that creates wall washing or radiance on the façade. With intelligent control systems, a media façade can be divided into multiple sections that can be controlled separately to display distinct content or can be seamlessly integrated together to form a giant screen. Innovations in media façade lighting are letting green buildings indulge in luminous storytelling. For instance, developing media façades with photovoltaic modules gain energy by absorbing sunlight during the day and convert it into an artistic lighting display after sundown. This version could be further enhanced by placing the solar cells on the roof for efficient sun orientation and energy absorption. Paying attention to the content that is to be displayed on these media façades is equally important as the engineering that goes behind creating them. It’s wise to consider the objectives,

involve huge costs of running and maintenance. Brand and building owners are opting for a few minutes of the display every hour instead of all night. Besides reducing operational costs, this also alleviates concerns relating to light pollution and any possible traffic distraction. Artificial Intelligence enabled technology is already prevalent in other spaces such as commercial and entertainment across platforms that engage and connect with people on a multi-sensory level. In lighting, the interactive LED technology has been mostly realised through music-to-light mapping - driving light fixtures based on musical input, and motion sensor technology operating light fixtures based on movement detection. Besides these, there is a great potential for other interactive data inputs such as voice recognition and data streams (from live inputs such as weather patterns). Dynamic LED lighting provides not only colour-changing as well as colourtemperature-changing products. While the interactive lighting control gives the ability to analyse and map data input in real-time. Each of the light points can be precisely controlled with multiple power states which correspond both to power consumption and light intensity. Though it requires further research, an intelligent, autonomous lighting control system can offer several benefits such as -

Sustainable façade lighting aims at minimising light emission in order to maintain a dark sky without light pollution that disturbs the biological patterns of nocturnal species. Directing light in a focused fashion helps in reducing stray light emissions. Light management and control systems facilitate control on intensity and duration, as well as provide maximum effect with lesser energy consumption. The façade of a building is an important feature that sets its aesthetic tone and ambiance. It’s vital to consider the right façade lighting solutions that enhance its beauty and symbolic value.

buildings is also on the rise. This is a late revival relatively as the South Eastern countries and the western world has already explored and is improving this aspect of the marketable space. As our lifestyles are adding more hours to outdoor activities, it is imperative for city centers / urban destinations to be receptive and more welcoming and needless to say - safe and dynamic. Parallelly, we have noticed that digital technologies are rapidly finding

their way into urban spaces. Façade lighting with multiple digital content possibilities hence has become prominent going ahead. In other words, Media façades are the order of the day. Today we have permanent media façade installations worldwide that compete for attention. These façades create unique identities for these buildings as they chatter and broadcast content/ graphics/ messages/ branding/ experience to citizens.

LED action façade, Madrid

The term “Media Façade” can be identified with façade sized screens that can be animated and illuminated in patterns which are created with intense programming using embedded LED lighting or projections. Popular destinations like Times Square, the Strip in Las Vegas and Hong Kong are pioneers for this media architecture. The façade itself is dematerialised and turned into one huge advertising medium for sending messages. As soon as the sun sets, the building moves into the background and serves only as a backdrop for the light show which then becomes the main attraction. Architecture tends to use media façades more and more as a stylistic feature. What used to be applied to façades after construction till only recently is now part of the planning process and offers new scope for visionary design which coined the term 'Mediatecture'. Due to their size, visibility and their technical capabilities, they offer great potential for interaction and for becoming the future displays of public spaces. FAÇADE LIGHTING First impressions count. Whilst a building’s appearance may not

speak, it can be perceived as an indication of the quality of the services provided inside. Factors like service, atmosphere and accessibility play an increasingly important role, but there is also the general image and reputation of a building, its owner and the designer. There is no qualm about the fact that with time, façade lighting is becoming a differentiator and also an imperative line item in modern buildings to attract footfall for extended hours and address the 24x7 lifestyles. More and more realestate builders, private buildings, IT Parks, hospitals, hotels and even municipalities are availing of this possibility to differentiate from their competition and in-process creating an urban lightscape. The cities/localities with façade lighting feel safer and more striking than areas without, often to citizens. Not only modern buildings, but also heritage buildings are being celebrated for night tourism supported by the Government. The landmarks, buildings and monuments that lie at the heart of a city are the essences of its unique heritage and identity. The right lighting can preserve that at

night, showcasing structures and materials and transforming the city into an alluring destination. Lighting creates exciting spaces that people want to spend time in, eating, drinking and taking in the sights. Lighting offers a great tool to improve people’s lives. By highlighting certain features and concealing others, it encourages people to discover the contours and details of the city that are not visible during the day. Human beings are like flies; attracted to light. So the trick is simple. POWER OF MESSAGING There is no shortage of regular form of media around us - print (newspaper, magazine), Broadcast (TV, radio), Out of Home Media (hoardings, signages), Internet (computers, mobile). In order to catch consumer attention, these mediums are fighting tooth and nail with each other as well as competition within their own segment. Advertisers are exploring new forms to reach their clients’ prospects. Media façade is definitely an impactful opportunity that lies open where the physical and the digital mingle and mediatecture is born.

2. Social impact: Many cities and regions across the developed countries have devised lighting events to attract visitors, enhance tourism. It is no secret that urban destinations are continuously striving for innovative ways to stand out and capture their share of the global tourism market. Many cities have used lighting to develop tourism and hence been able to spruce up their local economies. Example, Liverpool in England, Badajoz in Spain, Valladolid in Spain. 3. Revenue generator: Owing to easy programmability and transition, media façades can be sold to various bidders for advertisement rights. Also, the more innovative the façade lighting, the more footfall is assured

for the building, ensuring higher rentals and return on investment for the promotor. Example – India Trade Tower, Mohali. 4. Branding: There is branding for the brands and there is branding for the building itself. Even architecture needs brand positioning. Building with media façades is bound to have a better perception that its otherwise static neighbors. Also, since it is media-driven, the ability to adapt to any situation is observed as a unique attraction by citizens. The prime advantage being the

Types of Media Façade Technologies are evolving and empowering the building and lighting industry with many options for media façades going ahead. There are various types of media façades: 1. Pixelated: Very simply put these façades are typical billboards embedded with the façade elements to render a large screen experience wrapped around the building. The density of the pixels varies as per architectural elements as well as visibility desired for the media. Example, The Lantern at 11 Soho St, London.

Advantages of Media Façade in Modern Times 1. Marketing: Needless to say, because of their sheer size and visibility, the entire space is up for grabs for dynamic marketing. Whether it is public messaging or commercial advertisements, media façades are quite emphatic. Example NDMC building, New Delhi.

5. Public engagement: With governments promoting smart cities, it is imperative that citizens would become smarter and will need smarter environments to congregate and celebrate. Media façades are a very interesting canvas to engage modern citizens thru their interactivity. Example Dexia Towers in Brussels showcases interactive scenarios or temperature and weather forecasts and BCP Affinity in Peru lets the citizens control the media on its façade thru a large touchscreen accessible to pedestrians.

Lines of light: This is the stripped-down version of pixelated façade using lines of light (vertical, horizontal, slanting) creating a pattern along the columns, beams or any other prevalent elements of the façade. Example Hotel Intercontinental in Dubai, Harrah’s Atlantic City in Las Vegas 3. Mechanical media surfaces: At Jean Nouvel’s famous 'Institute du Monde Arabe' a mechanical media surface has been permanently integrated into the façade construction. The façade is made up of a lavishly constructed lattice window to which blinds have been attached which imitate those of a camera. Using their reaction to the intensity of the sun, light shining into the building can be regulated. The visible mechanics and the design of the blinds come together in an ornamental pattern that changes in interaction with sunlight. 4. Projections mapping: Projections form an intangible content beyond the surface onto which pictures are projected. The challenge is the interaction of the surfaces, the technology and the content of the projections.

WFM | JUL - AUG 2019

By using specialised software, a two- or three-dimensional object is spatially mapped in the virtual program which mimics the real environment it is to be projected on. Large companies such as Nokia, Samsung, Unilever, Bank Alfalah, Brighto Paints, Benson & Hedges, John Players Gold Leaf and BMW have used video projections to create campaigns for their products in major cities across the world. For example, Projection mapping at Fête des Lumières (Lyon Lighting Festival). INTERNET OF THINGS With the possibilities of IoT weaved in our day-to-day lives, media façades can’t be far behind. Enabled by IoT and cloud technologies it is possible to monitor, manage and program media façades remotely. Today, it is possible to create and trigger light shows from anywhere, while simplifying maintenance to protect the complex installation. Apps and Dashboards as newage user interfaces have made it friendly to use. So while the installation can be in Delhi or Mumbai, one can monitor and program it from a Chennai or Bangalore and vice-versa through cloud technology.

BALANCING ACT LIGHT POLLUTION Media façades can evoke the most diverse emotions, from a big city feeling to annoyance at light pollution. While the energy consumption is generally low owing to the advance technologies available, light pollution requires general concern when designing media façades especially when we are concentrating on the environmental impact of the façade on the surroundings. The negative effects cannot be denied, such as light scatterings that can annoy human habitat in the vicinity. There is a negative effect on nature and untamed life; inﬂuencing the behavior of natural life creatures, causing a negative effect on plants, inﬂuencing their development cycles, causing a dangerous effect on immigrant birds, which are diverted and getting perplexed. Moreover, billions of insects die on the surfaces of open lights, thus, decreasing regular nourishment for birds. In addition, offensive advertising could occupy drives, particularly amid evening time, causing accidents. It is therefore advised to exercise restraint by individual building promoters, designers

and authorities alike. Time will soon be ripe to draft guidelines to moderate the media façade lighting practices to ensure a balance of human business and nature alike. LEED (Leadership in Energy and Environmental Design) ratings also emphasise minimising light pollution by specifying thresholds of the percentage of lumens aimed upwards as per the building’s location and importance. The International Dark-Sky Association (IDSA) is another non-profit organisation that works to help stop light pollution and protect the night skies for

WAY AHEAD Going forward, media façade would become a permanent part of the urban space. Its context and surroundings affect how content is perceived and experienced as well. With the integration of digital technologies, such as projectors, light emitting or display elements, building façades in urban spaces offer new possibilities for interaction and engagement. Furthermore, the architectural and technological design of the façades raises the need for new approaches to plan and construct such façades, as well as to develop novel interactive installations to exploit the enormous potential of media façades. As India becomes one of the most sought after investment destination, it is bound to be seen upon by the Third world countries as a role model of development. While we may not aim to follow the developed nations in creating megapolis of limitless consumption, it is imperative to showcase sustainable growth by creating examples of sensible design and development. Media façades are yet to hit their prime in India and have a bright future. We need a sensitive, energy-efficient and contextual approach towards this new nocturnal adventure.

ADITI ANEJA

Head of Lighting Design and Specifications, Cinmar Lighting Systems, UAE

IMPORTANCE OF FAÇADE LIGHTING: COMPLIMENTING BUILDING EXTERIORS Façade design itself is approached in two distinct ways – one, the façade is simply a derivation of the plan. And two, it is developed as a separate design exercise and has little to do with how the building is actually laid out internally. In the latter case, the form is usually stressed more. Both the cases have the potential to make for very engaging and striking nighttime façades, observes Harmeet Singh Issar, Founding Partner & Design Director, Design Matrix. It may seek to integrate with the architecture and simply highlight the elements – ‘façade for light’; or it may serve to create a distinct identity and seemingly transform the façade by night, yet obviously dovetail into the architecture – ‘light for façade’. Indeed, lighting does much more than bringing out every curve and crevice of the façade; it imparts a personality to building and structure. The façade is the first feature to be noticed about any structure and it is the preamble to an architect’s work. It is the responsibility of the lighting designer to pick the right architectural elements, understand the architect’s story and enliven the

character of the structure at night, points out Aditi Aneja, Head of Lighting Design and Specifications, Cinmar Lighting Systems, UAE. The façade lighting not only helps to localise buildings and provide security, but it also plays a key role in the architectural expression. The elements of the building, where an architect and structural engineers have put up a lot of efforts to make it a benchmark has to be highlighted as one of the most prominent elements of the structure, thus appropriate lighting can complement its exterior, says Sushant Surve, Principal designer, Brainwave Designs & Associate. Debmalya Guha, Principal Architect and Planner, Pace Consultants, adds that a creatively illuminated building can make the most memorable impression as it gleams far and wide in the darkness of the night. According to Indrajit S. Kembhavi, Principal Architect, Kembhavi Architecture Foundation, façade lighting adds aura and identity not only to a building but also to cityscape and skyline. It enhances and expands the expression of the façade. It presents multitudes of aspects and dimensions to the façade from static to dynamic, he adds. Whether it is day or night lighting,

lights usually help pull attention to texture, shapes, spaces and colours, assisting the architecture in attaining its purpose. Vision is the single most key sense through which we relish architecture, and lighting enhances the way we perceive architecture even more, points out Shabbir Kanchwala, Senior Vice President, K Raheja Corp. Ar. Prem Nath, Founder, Prem Nath & Associates agrees that both daylighting and artificial lighting draws attention to textures, colours, and forms of space, helping architecture achieve its true purpose. “Buildings can be turned into genuine landmarks. The façade lighting plays a key role in the architectural expression. To match the different finishes on the exterior of a building (be it glass, zinc, stone or metal), along with different colours, finishes and type of materials, outdoor lighting fixtures are fixed in order to complement them all”, says Ar. Prem Nath. Blending of exterior façade lighting with interior functional lighting should be done by analysing the type and size of fenestrations in the façade, and fenestration, in turn, need to be carefully placed depending on the climatic conditions of the area and the specific function for which the building is designed, points out

Prof. Charanjit Singh Shah, Founding Principal, Creative Group. Along with making the building safe and easier to approach during night time, it enhances the architectural expression and emphasises its design features, natural shapes and surface structures. The building at the same time, should not contribute to light pollution, a condition where excessive artificial lighting during night time disturbs the natural habitat of the nocturnal species, adds Prof. Shah. According to Ar. Gurpreet Singh Shah, Principal Architect, Creative Group, façade lighting plays a major role as it enhances the elevation in the interior or the exterior of the building. It emphasises the architecture, the structure, attracts attention. Also, the various lighting makes the experience transforming the architecture and mood of the building. Now a day, through lighting one can communicate messages, convey information. It helps in the promotion of the economy & tourism, sustainable lighting and security aspects are also some factors which add on to the marketing factor. Apart from emphasising artistic expression, façade lighting should also contribute to the branding and marketing for the investors, landmarking for the city planners, ensuring sustainability for the environment and lastly, imparting

a “local essence” to the structure. It also attracts tourists, employees and customers as may be the purpose of the structure, adds Aneja. Only monuments that had a lot of ornamentation such as historic buildings and palaces used to enjoy grand lighting schemes earlier, points out Pavitra Sriprakash, Architect, Shilpa architects. Today, however, a lot more contemporary architectural forms enjoy dramatic lighting details that almost play with the light and shade to create visual impressions that are not merely ‘illuminating’ the façade – but are actually becoming a part of the architectural interplay between form and light. Light filtering through trellises and transparent surfaces, colour changing façades of different moods, accent lights that form narrow beams and patterns on the surface – all of these are possibilities for architects and designers today. According to Radeesh Shetty, Lighting Designer & Director, The Purple Turtles, façade lighting has a classical version, which lights the

building in a conventional way, and a modern hi-tech version, which allows the use of dynamic lighting to create video walls and even render a 3D impression on the building. By emphasising the architectural form, façade lighting makes a building more vibrant and attractive. Ar. Prem Nath explained the unique lighting effects that can create a 3D impression, and give buildings their own character, making them popular attractions in the cityscape, both day and night. Intelligent sensors and controllers enable the systems to adapt to daylight brightness levels and create a lasting impression in all weathers; this totally compliments the façades of the building.

Role of Façade Lighting • Façade lighting plays an important role in the way people experience and understand architecture. • Whether buildings and structures are lit naturally or artificially, lighting is the medium that allows us to see and appreciate the beauty in the buildings around us. • Lighting can bring an emotional value to architecture – it helps create an experience for those who occupy the space. • Light draws attention to textures, colours, and forms of a space, helping architecture achieve its true purpose. • Enhancing the night image of important functional or architectural significance. • Providing vertical illuminance in the adjacent area to reduce contrast with the pedestrian lighting and to reduce shadows. • Provide visual cues to assist people’s orientation at night. • Highlighting or decorative lighting shall be designed to avoid excessive energy usage and shall use high efficacy light sources consistent with the other external lighting. • Where highlighting of buildings does not serve a dual purpose of public lighting, the lighting shall automatically switch off at midnight.

Please list a few checkpoints to consider for best façade lighting solutions? Proposed lighting design for façade lighting should increase the beauty of the modern building and complete heritage monument and create a signature mark without affecting the structure. Lighting can be plane or dynamic as per the design intent. The energy-saving aspect should be taken care of as façade lighting has longer operating hours. Since it’s a type of outdoor public space lighting, higher degree of protection from the sun, wind, rain and insects needs to be considered. Theft proof installation is recommended. Care should also be taken to make sure that the poles and accessories used for façade lighting should complement the structure and not appear sore to the viewer’s eye. The lighting materials used for façade lighting should either be concealed or placed in such a way as to not obstruct the view of the visitors in the daytime.

Please throw some light on the standards, local norms and regulations for outdoor lighting? The Indian Green Building Council’s (IGBC) Green New Buildings Rating system prescribes reducing the light pollution to increase night sky access and enhance the nocturnal environment. Following parameters need to be followed while designing the outdoor lighting: • Minimise light trespass from the building and site • Reduce skyglow to increase the night sky access

WFM | JUL - AUG 2019

• Improve nighttime visibility through glare reduction • Reduce the development impact of lighting on nocturnal environments Avoiding glare to reduce light pollution and being sensitive towards the creatures that are active at night, such as insects and migrating birds, is the most preliminary precaution that we have to take while lighting up façades. Scattering any light beyond the façade surfaces, either to the sides or over the top, should be avoided. Glare light scattering

in the eye causes loss of contrast and leads to unsafe driving conditions. Both the LEED and Green Globes Systems call for extremely low illumination levels at site boundaries for the park and rural settings, with moderately higher levels permitted in residential zones and somewhat higher levels in commercial and entertainment districts. Suggested means for achieving these goals include the selection of full-cutoff luminaires and low-angle spotlights, use of lowreflectance exterior surfaces, and restriction of lighting to critical areas. From ecology perspective, supporting The Dark Sky movement, reducing the light pollution will facilitate visibility of an increased number of stars at night, reducing the effects of electric lighting on the environment, improving the well-being, health and safety of both people and wildlife while cutting down on energy usage and making the lighting sustainable. In case of usage of certain lighting, like searchlights, we need permission from the aviation authority. We also need to take into account local traditional and cultural lighting aspects while designing lighting for façades. What is the impact of façade material on façade lighting? How is the rising trend for glass façades affecting façade lighting? The form of façades is determined not only by their material and shape but also by the light and its direction and colour.

Cover Story direct light. For highlighting the brick-work texture, warm white is used. For highlighting metal surfaces, wallwashing, no beam effect is used. For glass façades, interiors are brightened up and contours are highlighted to get the façade lighting effect. Indoor lighting allows the observer to see into the building. Ceiling wash lights in the indoor area emphasise the ceiling surfaces and increase the overall impression of interior brightness at night. Please brief on the latest trends in lighting systems and lighting controls. In earlier days, façade lighting was done using MHL/HPSV floodlights, up-lighter and wall lights. With the latest development in LED technology, dynamic façade lighting is becoming more popular. LEDs offer a variety of fixes as well as programmable colour outputs. Normally both types of luminaires i.e. fixed colour as well as fully programmable is used for façade lighting. In case of programmable LED luminaires, each LED product has red, green and blue LED chip and the intensity of each type of LED is controlled by using a sophisticated control system in order to achieve 16 Mn colours. Use of RGB LED luminaires is also termed as dynamic lighting solution for façade lighting. Dynamic façade lighting makes use of various shares, wattage and beam angle LED RGB luminaires along with the DMX controller. DMX controllers are more popular due to their compact size and faster rate of data transfer which is required in RGB luminaire control. This kind of dynamic lighting can create different themes like tricolour during 15th August or 26th

Wipro Lighting's Arcus is a premium outdoor architectural lighting solutions range that caters to multiple façade lighting requirements. Tell us about future trends and technologies in façade lighting. As modern commercial buildings are becoming smarter, façades are becoming more dynamic. The future will witness the dynamic lighting using transparent pixel screens as the most rising trend. Also, using transparent pixel screens for animation and control on façades will be another upcoming development in façade lighting. For monuments, bridges and heritage buildings, use of colour changing LEDs can easily create interesting and mesmerising effects to highlight the beauty and grandiosity. Day-by-day, LED lights are becoming compact and sleek, helping to make façade lighting clutter-free. Ease of control and tuning of LED lights will help to create interesting patterns in such structures. How can we use façade lighting as a marketing factor? Façade lighting sets the stage for different monuments, buildings and cities, thereby shaping their image. It highlights the buildings and cities, thereby attracting more and more visitors and tourists to the place. Creative lighting patterns and textures reinforce an emotional connection to the buildings and enhance the beauty of the cityscape. This boosts revenues and enhances prestige. Aesthetically lit façades of modern commercial buildings help in brand building by attracting more and more

visitors. It also gives investors an economic incentive to renovate and upgrade property usage, thus making it economically more attractive. Thus, façade lighting creates added cultural value. It is important to go for sustainable façade lighting having responsibility for nature, resources and the environment. How can we achieve this? Saving energy is an omnipresent challenge, façade lighting must, therefore, get to grips with ecological compatibility issues. The number of buildings that have illuminated façades is increasing sharply. All lighting entails increased expenditure on energy. Aesthetics of buildings and cities must be weighed against the responsibility we bear in our day-to-day dealings with nature, resources and the environment. Improperly used night-time lighting can have a negative impact on the environment. The light that is not properly directed onto a façade is perceived as distracting and an unnecessary waste of light. Such lighting disrupts the biological processes of creatures that are sensitive to light. Stray light that shines into the sky consumes unnecessary energy and adds to light pollution. These challenges must be considered by designers and architects in their attempts to find a balance between using light in a way that saves resources and creating added cultural value. Façade lighting solutions need to be sustainable, save resources and prevent unnecessary light pollution. The use of programmable and intelligent LED lighting solutions for façade lighting is one way towards sustainability.

Cover Story LIGHTING OPTIONS Façade illumination, notes Sandeep Adagale, Lighting Design Director, Lighting Dimensions Studio, is the process unfolding the architectural elements through the various layering of light. A façade’s form appears different, based on the light that falls on it, its direction and colour. The appearance of a façade alters during the course of the day due to the changing direction of light, and the varying components of diffused and direct light. Direct lighting: Lighting where more than 90 percent of the light goes directly from the source to the area you wish to illuminate. Directed light: Light produced by point surfaces, which results in a concentrated output that accentuates edges and shadows. Directed light normally causes glare when the source is viewed directly. Uplighting: Lighting method where an object or surface is lit from below, with a luminaire that directs its output upward. Wall grazing: Lighting effect where a wall with an irregular surface is illuminated so that there are both highlighted and shaded areas. This effect is only possible on the walls with granular surfaces, such as those built from stone or exposed brick. The opposite effect is wall washing. Wall washing: A lighting effect, where a wall is illuminated so that surface irregularities are minimised, it seems smoother. The opposite effect is wall grazing. The simplest form of architectural façade lighting is uplighting of classical architectural elements, explains Sriprakash. This is particularly interesting when there are many windows or columns that can be simply lit for an elegant and somewhat predictable but

timeless look for any classically designed building. The other play of light which is interesting instead of the typical wall washing or up lighting technique is, of course, the use of LED’s which are dynamic and keep changing – whether it is their shape, the colour or the beam of light that they throw onto a façade. Façade lightings work cohesively with the architecture to highlight its best features. According to Shetty, uniform vertical lighting accentuates the building façade without altering its form. While focused lighting draws attention to distinctive architectural features on a building façade. Contour lighting illuminates and differentiates the foreground from the background of a building. Creative lighting patterns can be used to make an emotional connect with the building, in a way that it amplifies its cultural value on the façade. Interactive LED lighting systems merge rear projection and motion tracking technology that turn a façade into a two-way communicative medium, adds

Shetty. In addition to the said type of lightings, Ar. Prem Nath spoke about media façades. “Today, we have permanent media façade installations worldwide that call for attention. With size, tempo, colour and brightness they stand up as individuals within the urban nightscape. Like a good book

requires a storyteller, media façades demand architect’s innovation to arrange exciting stories that fit into the site and suit the client. It’s totally how the lighting solution is used/placed in order to create a great impact”, he explains. METHODS OF FAÇADE LIGHTING Myriad solutions are possible with the advent of smart façades and state-of-the-art lighting systems, says Aneja. “After determining

the goal of lighting, I suggest a two-pronged approach to finalise a solution: first is to study the façade and second is to apply the right technique”, she points out. Silhouetting, layering, grazing, contrasting and highlighting are some techniques. Apart from these, subtle play with beam angles, intensities, colours and dynamic lighting adds rhythm to façades. Issar talks about three broad types of façade lighting: 1. Architectural façade lighting: Light is applied to enhance the structural and architectural details – light is there for the façade, as per the façade. Successful lighting design is, however, dependent on effective collaboration

The Glitter Effect The State Bank of India, local head office at the Gift City Gujarat: The ground plus 13 upper floor structure is designed in an iconic fashion. The visual appeal of the building is through the linear and symmetrical form. The building structure is aesthetically designed in a way that the service core is planned towards the western side of the building. The office space makes maximum use of natural daylight and outside view. The architects, Prem Nath & Associates, have used spotlights on the glass façade to create a glitter effect, which is quite attractive for the public space during the night.

between teams to ensure that light sources are integrated within the architecture so that the effect is showcased rather than the fixture. 2. Pixelated façade lighting: These have been made better with the advent of solidstate lighting. They use the architecture as a blank canvas to paint an entirely different night time picture or message or identity. These façades offer greater opportunities for engagement of the public as they are often interactive or can be easily made interactive. 3. Projected façade lighting: While projected façade lighting is dynamic, its huge advantage lies in the fact that it can easily be done later or changed later. However, due to the nature and cost of equipment, they are more popular as temporary or event-based applications. According to Surve, the illumination of façade should be done keeping an eye on the surfaces, materials and the degree of reflectance. The step to basic illumination of a façade is normally executed by breaking into simple shapes to which a uniform illumination is applied and accent lighting is used in order to emphasise a particular element. The façade lighting approach initiates with the following: type of building (corporate office, hospitality, residential towers, malls, worship centers), solid façade, vertical façades, horizontal façades, façade with projecting or recessed sections, perforated façade, banded façade, and transparent façade. Adding layers and patterns of light to a flat solid façade will give dimension to the façade while a perforated façade is best silhouetted with backlighting and best contrasted with brightly lit windows and other openings

WFM | JUL - AUG 2019

Cover Story from the inside. For solid façades, generally, the approach is to wash the building uniformly, whereas on perforated façade, illuminating the window accentuates the frame of the façade opening, whereas narrow-beam uplights emphasise the façade‘s grid pattern. However, good design practices need to be followed to avoid any glare or discomfort to the functioning indoors. Varying light intensities, distribution patterns and colours are a great way to light façades with projections or recesses. Façades with vertical breaks can be augmented by using narrow beams of light while adding lines of light on every floor-ceiling breaks the monotony, says Aneja. On vertical façades, adds Surve, floodlights produce uniform illumination. Washlighting with point-shaped light sources is suitable for horizontal façades since the surface texture and structure will be clearly visible, accentuating the columns from the surrounding façade. Uplights positioned on two sides emphasise the volume of the column. Façades with horizontal breaks cast strong, short shadows and this can be prevented by projecting light at steeper incidence angles by luminaires placed at a greater offset, points Aneja. For horizontal façades, Surve advices on floodlights to illuminate the entire façade and to emphasise the horizontal divisions by casting heavy shadows. Indoor users should not be dazzled. For banded façades, illuminating the indoor areas at night forms a strong contrast between dark façade surfaces and a bright strip of windows. Lighting transparent façades can be tricky as no spill light should impair any activities in the interior of the building. Bright indoors with down-lighting is preferable as this gives the illusion of a more spaced out upper structure for a viewer

from outside. Uplights emphasise the vertical elements of the façade in the case of transparent façades. Façade lighting is not a problem that needs “solution”, rather it needs a creative approach to visualise a soothing yet appealing design that does not guzzle energy or cause night-sky pollution, observes Guha. When deciding on the right lighting concept for any architecture, says Kanchwala, the design and usage of the construction play a critical role. Façade lighting creates added cultural worth. External lighting of historical buildings, for example, must highlight the structural elements, such as mouldings, cornices and reliefs, without altering their perception. The correct lighting can add value, expressing the architectural importance to reflect a positive image. According to Ar. Shah, if lighting deals sensitively with architecture, the character of a façade remains the same, day or night. Uniform, wide-area illumination of a façade reveals its natural shapes and surface structures. While the building’s appearance is preserved, the architecture speaks for itself. Using white light to pick out individual columns, ornaments or projections in the darkness is another very popular option. Different rules apply at

night. If characteristics, contours or structures can be identified, this creates an impression of threedimensionality. A professional lighting concept lends a building special flair. Taking the environment of a building into account as a design element in its own right results in a high degree of naturalness. EFFECTS ON ENVIRONMENT Light pollution is a major issue and in today’s age the sustainability factor needs to be balanced with the ‘wow factor’, says Sriprakash. Improperly used night-time lighting can hurt the environment. Such lighting disrupts the biological processes of creatures that are sensitive to light. Disrupting sleeping patterns of nocturnal animals is an absolute no go, and architects need to be sensitive to the angles of illumination they choose to adopt. Stray light that shines into the sky consumes unnecessary energy and adds to light pollution, which exacerbated by excessive, misdirected or obtrusive uses of light. Prof. Shah observes that a sky glow occurs when artificial light which shines upwards, reflects off clouds and atmospheric particles such as dust and water, causing a ‘scattering’ effect. Too much light is a sign of poor design skills, points out Guha. One should try to use the

Cover Story optimum amount of light in the right temperature, and selectively accentuating distinctive features of the building, thus creating a fascinating design. According to Sriprakash, other than the light pollution, the major aspect is the interference with the building occupants very often inside commercial buildings - is the glare coming into the workspace from façade lights which may not be properly planned. This disrupts the working conditions within the building Using luminaires with high efficacy, avoiding light pollution and trespass, using technologies that are reliable and proper planning of the location of drivers and their access, all contribute towards a successful, sustainable façade lighting design, adds Issar. According to Prof. Shah, façade lighting can be made sustainable by using the Building Management System (BMS) which allows for timers, dimmers and luminosity regulation, enhancing controlled visual impact as the night falls. The façade lighting should not disturb the environment but instead complement it.

Light pollution is excessive and inappropriate artificial light. • Light trespass: light falling where it is not intended, wanted or needed • Glare: excessive brightness which causes visual discomfort. High levels of glare can decrease visibility • Clutter: bright, confusing, and excessive groupings of light sources, commonly found in over-lit urban areas. The proliferation of clutter contributes to the urban sky glow, trespass, and glare

CHECKPOINTS Guha articulated on the many options for light fixtures, light colours and controls, which are flooding the market that is completely drowning the fine art of illumination design. “Over-lit façades with jarring colours are becoming too common creating a jarring nightscape of the cities. ‘Façade lighting solutions’ are being provided by suppliers who are more often interested in using more than the required number of fixtures creating illuminated disasters at exorbitant cost”, he adds. The lighting design must be context-appropriate, says Issar.

This implies that is must suit the style of architecture, the building typology, the location and setting as well as client aspiration and budget. Ease of access and minimal maintenance are usually very crucial features of successful façade lighting. Since it involves installing and accessing lights in hard to reach places, technology and quality of the luminaire must be robust. It serves as a strong marketing tool and the conveyor of the brand image. A single luminaire going wrong can be very visually disturbing and reflects badly on the brand. One aspect that is often an afterthought in the façade lighting design is the placement of the drivers on the façade which is an extremely critical part of the design. According to Kembhavi, material typology, uniformity/ diversity, maintenance, efficiency, environment and responsibility, purpose and function, and opex and capex are the various criteria to look at while lighting the façades. Broadly, three types of checks should be made, says Aneja. 1. Façade check: Material, length and breadth to be illuminated, façade strength to hold the lighting fixture, fixing mechanisms possible, and access to luminaires for maintenance should be evaluated. 2. Environment check:

WFM | JUL - AUG 2019

Cover Story Temperature (highs/ lows), humidity, etc. determine the rating of the cables, luminaires and the drivers. Weather conditions like snow, rain, sandstorms, etc. also determine the temperature rating, wind resistance, IK rating, IP rating, material as well as the electrical characteristics of the luminaire. 3. Product check: Glare control, correct aiming, lenses, right shielding accessories (louvers, gobos, etc.), proper luminaire placement and correct lighting calculation will provide visual comfort to nearby and distant viewers. Aneja mentions about checking colour quality too. A basic check on the CRI rating is a good idea and for façade lighting, there is no need to go into CRI extended values. Also colour temperature plays an important role; with preference of warmer colours in colder regions and cooler tones in hot and tropical regions. The checkpoints according to Suvre and Kanchwala are, the category or usage of the building, design and environment, type of façade material, light source, vandalresistant, maintenance-friendly, minimum light pollution, dynamic lighting, light management

systems, uniformity of lighting, power-saving and environmentfriendly. Adagale explains some of the above-mentioned checkpoints: • Selection of material for outdoor fittings: Based upon surrounding conditions, we prefer high pressure die-cast aluminium with very less percentage copper content with superior grade powder coating or 316L stainless steel housing. • Ingress Protection rating (IP rating): IP rating stands for international protection rating and classifies the degrees of protection provided against the intrusion of both solid object and water in electrical enclosures. We Prefer to use all products above the IP65 rating. • The efficiency of lighting: To achieve an energy-efficient solution, one must calculate how much lumens of light per watt of electricity the lighting system delivers. • Colour temperature: The Correlated Colour Temperature (CCT) describes the colour

output of the lamp itself. It varies from 2700K (warm), 3000K (warm white), 4000K (neutral white), and 6000 K (white). • Types of light source: Nowadays we recommend only LED with its new technology provides you with a long-lasting solution and minimal maintenance. • Glare control: The visual comfort is important for the users and their surroundings. The glare may be visible from nearby or distant areas but can be minimised through good design practices. • Light pollution: Light pollution can be described as artificial light allowed to illuminate areas not intended to be lit. Make sure the lighting plan is good and the selections of products are well suited and aimed at the correct area. Adding to the above-mentioned points, Shetty suggests that the lighting fixtures installed on the exterior walls should be lighter in weight and made of material that helps it to withstand varied weather conditions, thereby ensuring it’s long-lasting and energy-efficient.

motion detectors and daylight control will ensure safety and costefficiency. Installing façade lighting fixtures at accessible points make it easier for maintenance and repair. LIGHT SOURCES Metal halide and high-pressure sodium light sources, though tried and tested, are now extinct. LED lighting “systems” with complete light control and management is trending. LED video screens, media façades are the latest in line, says Aneja. Agreeing with her, Kanchwala adds that the revolutionary development of LEDs has opened up fresh design approaches for façade lighting. The controllability of the brightness and light colour of LED light sources, together with their diverse optical characteristics, are making innovative technical lighting solutions possible. A poorly designed LED lighting product can lead to faster overheating, faster lumen depreciation, light discoloration, and much shorter life of the lamp.

personnel only need to access the control room where the light source is housed and not the façade; this is a very safe solution for tall structures. Ar. Shah says that the ETFE Multifunctional Module aspires to enhance the use of BIPV in the construction industry, providing new architectural façade lighting possibilities. It demonstrates the multiple uses of ETFE architecture, showing it as a versatile material with potentially wide application. STANDARDS, LOCAL NORMS & REGULATIONS FOR OUTDOOR LIGHTING The Energy Conservation Building Code (ECBC 2017) talks about energy efficiency in outdoor lighting and reduction in lighting power density to increase energy efficiency, notes Kanchwala. The National Lighting Code (NLC) published by the Bureau of Indian Standards has been formulated to set out in a convenient form the requirements for responsible social, commercial and engineering conduct for the designers, manufacturers and suppliers of lighting. ANSI/ASHRAE/IESNA

Standard 90.1 are some of the international codes which are frequently used for outdoor lighting designs. Right now the façade lighting norms don’t seem to be well defined as the industry in India is still in infancy stage. According to Adagale, the International Commission on Illumination (abbreviated as CIE from its French title) is an organisation devoted to international cooperation and exchange of information among its member countries on all matters relating to the science and art of lighting. He talks about CIE 154:2003 maintenance of outdoor lighting systems. He also explains that the European Standards (EN) can be distinguished by content, which is decisive for the purpose of the use of terminology, basic, test, product standards, safety rules, procedures and standards of services, quality management standards, interface, interchangeability, etc. One can follow EN 12464-2 light and lighting for the lighting of outdoor workplaces. In India, in the case of a heritage building, the approvals should come from ASI. Ar. Prem Nath, says that every aspect of the building, be façade/outdoor lights or the structure, have to be designed with the concern of the Urban Art Commission. Most state laws are limited to outdoor lighting fixtures installed on the grounds of a state building or facility or on a public roadway. The most common dark skies legislation requires the installation of shielded light fixtures which emit light only downward. Replacement of unshielded with fully shielded lighting units often allows for use of a lower wattage bulb, resulting in energy savings. Other laws require the use of lowglare or low-wattage lighting, regulate the amount of time that certain lighting can be used, and the incorporation of Illuminating Engineering Society (IES)

guidelines into state regulations. According to Sriprakash, some cities in India have processes which restrict the usage of advertising and LED screens on the façades. In general, norms and regulations are centred around safety when it comes to outdoor illumination or energy. When it comes to façade lighting, there are some regulations on the types of fixtures that are allowed – cut-off fixtures that do not travel upwards into the sky are usually preferred. The energy conservation and lighting loads are also a factor to understand how much we can afford to ‘spend’ on façade lighting. “In the UAE, we follow the ADM Abu Dhabi municipality manual, Dubai municipality compliance guidelines and estidama regulations”, says Aneja. Many private projects need clearance from local authorities. For more general compliance, one can refer to CIE and BS standards, though the local gulf standards are more rigid as they take into account the harsh weather conditions and proximity of the sea. Light pollution

and sustainability are taken very seriously in these standards. IMPACT OF FAÇADE MATERIAL ON LIGHTING The material is a large determinant for any lighting and will dictate the direction, amount and type of lighting the surface will receive. With smart façades and newer composite façade materials honing the market, lighting designers also have to upgrade to newer sustainable lighting technologies. Studying the façade surface (flat or patterned) and its strength to hold fixations, light reflectivity, incident light dispersion properties, colour, and material composition - all these play a vital role in the selection of the lighting technique and the product, says Aneja. Every material behaves distinctly when illuminated, says Guha. One needs to be aware of the right colour, temperature and intensity of light that is required to get the best visual effect. Too much light may create light burns, while too less may leave it under illuminated. The material palette of future façades is evolving rapidly

ranging from ceramics, multilayer aluminium/metal, to ETFE (ethylene tetrafluroethylene copolymer) cushion fabric, multilayer ETICS (external thermal insulation cladding system) to green vegetated façade systems, adds Ar. Kembhavi. ILLUMINATING GLASS FAÇADES Various types of glass façades have been in vogue, from translucent to twinkling with rainbow effect to reflective glass and optical illusion, observes Shetty. Glass façades encourage innovative ways to incorporate colours and even colour changing systems in façade lighting that are customisable and attention-grabbing. Also, there are glass façades with internal illumination that result in uninterrupted glass and light across façades, adds Shetty. Glass is a unique material that cannot be illuminated as light passes through it. It can have varying effects due to its reflectance, transparency and colour - just like water when hit with light. One has to tread carefully when there is a glass façade as internal lights

Cover Story will be visible through the glass and interfere with the façade illumination, points out Guha. The design skills of the architect help to decide on how to create a fascinating illumination design, merging the leaking lights of the glass façade area, etc. The façade illumination should not be disturbing the occupants of the building. Backlighting or lighting from the inside to the outside is great for glass façades. It is visible on the outside and yet causes no glare in the indoors. A modification to backlighting can be made if pixel lighting is employed. This would make up a low resolution or a high resolution dynamic graphic screen! Sandwiched translucent glazing could be used effectively to generate interesting illumination through colour changing etc. Opaque surfaces could be used in highlighting, contouring and accentuating, observes Kembhavi. For glass façades, says Issar, instead of lighting the façade, one can look at ways of lighting from the inside out – using indoor lighting to contribute towards the night-time image. A lot of dynamism may be derived from the variation in the interior lighting if left to the users/ tenants/occupants. Alternately, peripheral interior lighting may be taken care of by the developers/ owners for a well-composed, even façade lighting design. According to Sriprakash, the opaquer the façade the more interesting the lighting play can be. Creating small recesses within the glass façade and housing light elements within them can create exciting visual effects on an otherwise simple façade. The use of opaque coloured glass in double skin façades can also create very exciting architecture which is simple yet makes a statement, she adds. From basic spotlighting to glitter effect with LED can be used on

glass façade to illuminate it, says Ar. Prem Nath. “Now you can also harness the LEDs embedded inside Glassiled to open up whole new dimensions for your creativity. The LEDs either monochrome or RGB are powered via a superefficient, transparent conductive layer,” he adds. LATEST TRENDS IN LIGHTING SYSTEMS & LIGHTING CONTROLS Smart and miniaturisation are the keywords trending, observes Aneja. Lighting can now be controlled through phones, tablets or Alexa! This is due to the marriage between LED technology and AI. Many programming languages are written by façade lighting luminaire manufacturers. This makes for a complete package and a one-stop solution for the buyers. Integration of data services, Wi-Fi along with online surveying agencies will lead to seamless integration of all gadgets, and lighting will no longer be a separate entity and its use will not be limited to visual purposes. Surve spoke about the indoor location tracking, camera-based lighting control, self-learning control systems, integrated street lights, healthier lighting, human-

centric lighting, etc. as the latest entries in the field. Architects are becoming increasingly aware of the cost savings and reduced energy consumption benefits of lighting control technology, including occupancy sensors that are most effective where there is constant traffic, timed switches based on elapsed time or programmed according to specific schedules, dimming controls, or a combination of these options, observes Ar. Prem Nath. While opting for façade lightening, people go for options which have more lighting controls, such as user-friendliness and adaptability, energy efficiency, and good-quality light to help save energy, says Kanchwala. The need for efficient lighting and power saving is also driving advances in occupancy sensors and largerscale fluorescent control systems. Recently, self-adjusting, adaptive controls have replaced manual dials and eliminating multiple trips to fine-tune sensor settings in a large environment. Talking about the commercial market, there is an increased demand to integrate dimming and to switch

sensors, programmed switches and dimmable controls, which facilitate cost savings and reduced energy consumption while meeting the requirement. Selfadjusting adaptive controls and wireless systems are replacing manual sensor settings in advanced technology. Integrated

lighting systems are in demand as they facilitate security and safety along with energy savings. The faรงade lighting industry is growing by leaps and ranging from dynamic to virtual reality through a screen, throwing out information/stories using it as a medium of advertising/display/ positioning, notes Kembhavi. From a control perspective, it could be fused seamlessly to varied functions of the building through BMS/IOT. Faรงades could also be responsive, informative and help in collecting mass data. Pavitra Sriprakash adds that in dynamic lighting, different areas and features can be individually controlled, based on different scenarios like a changing rhythm based on time of day. These can be used to create various aesthetic scenarios or can adapt to the usage patterns of the occupants within the space. Through this type of automation, smart usage of the lighting can evolve balancing the energy usage, the aesthetic and the programmatic needs.

Latest in LED Lighting

Economical controllability: Ensuring dimming performance in fluorescent and high-intensity discharge (HID) luminaries typically required a dimmable ballast that imposed a cost premium. Today, dimmable LED luminaires are available at price points that are competitive with standard ON/OFF and bi-level luminaires. Intelligent lighting: The majority of LED luminaries are dimmable. When evaluating a control solution, one must always ask what method or protocol the devices use to communicate. The most common method is 0-10V. As LED sources are digital devices, however, they are readily compatible with digital controls. This has created significant opportunities for intelligent LED lighting that offers an extensive array of features. Wireless technology: Wireless sensors and LED lighting, both luminaries and lamps, are now widely available. This extends applications, facilitates adoption of intelligent lighting, and can make retrofits involving more sophisticated control schemes easier to implement.

Colour tuning: A growing number of LED products allow control of the shade of white light output, from full-range white light colour temperature modulation to dim-to-warm control. This has opened new applications for LED lighting, but with extraordinary potential as interest grows in the relationship between lighting and health.

“Façade Lighting is a Social Phenomenon”

Please list a few checkpoints to consider for best façade lighting solutions. To achieve good façade lighting design, one should consider the following considerations • How to light? • Responding to the macrolevel context – city level, master plan, etc. • Responding to the typology

of function – retail, office, healthcare, etc. • Responding to the concept of the building – façade elements, patterns, contrasts, etc. • Responding to the microlevel context– immediate neighbourhood, local milieu • What to light? (Viewpoints, etc.) • Responding to the microlevel context – controlling glare, safety of pedestrians, etc. • Responding to the typology of function-specific spaces, elements, etc. • Responding to the concept of the building – columns, windows, arcade, voids, etc. Also, it is imperative to take into account the

height of the elements, position of luminaires, width of the elements, surface texture, reflectance and colour of the façade elements. One cannot avoid to also check peripheral lighting in the surroundings, proximity of light sources to people, camouflaging of luminaires, and weight of luminaires as well as light pollution. Please throw some light on the standards, local norms and regulations for outdoor lighting. Façade lighting in India does not fall under any regulation as far as my personal knowledge stretches. On the contrary, outdoor lighting does have multiple standards for lighting levels, glare and lighting pollution as well as on energy consumption. Façade lighting has been although covered under the Bureau of Energy Efficiency from energy consumption perspective in ECBC 2016. As far as light pollution is concerned, LEED ratings control the number of lumens being thrown above nadir (0 degrees) as per the classification of the building’s importance and location. It is startling to know that light pollution is on the rise in India and it is important to have a balanced approach. What is the impact of façade material on façade lighting?

The texture of the material of the façade is the smoothness or roughness of the surface of a material. This determines the design intent of lighting as follows: • Highly textured surfaces: Should focus on enhancing its texture through effects like grazing. • Smooth surfaces are best suited for a homogeneous impact though effects washing and flooding. Glass/ACP façades are not the best surfaces for illumination from a distance. These façades need lighting to be weaved as part of the glass sub-structure, much in advance, whether direct view, LED screen, lines of light or light-filled voids. Glass façades are being welcomed with new-age lighting techniques, just that the installation of the lighting should happen with the façade execution. It cannot afford an afterthought, else the whole design will become an eyesore during the daytime. Please brief on the latest trends façade lighting controls. Lighting controls are of extreme importance as there is no regulation of this new age possibility so far. Lighting controls not only add various possibilities to the façades from an experiential perspective (multiple programs-

hour-wise, day-wise, occasion-wise, colour-wise, speed-wise, interfacewise), but it also helps regulate brightness, energy monitoring as well as ease operation and maintenance of the installation. In addition, with the advent of the Internet of Things, it is now possible to monitor, manage and program dynamic façade lighting installation using software and system architecture which are based on cloud technology. So remote lighting controls are the latest possibility with multiple benefits. It is important to go for sustainable façade lighting having responsibility for nature, resources and the environment. How can we achieve this? Façade lighting is a social phenomenon even if it involves a privately built form. With this new urban canvas which is receptive to dynamic, public-source content it is imperative to maintain restraint from going overboard in terms of content, to begin with. Apart from the same, we should respect our co-habitants of the planet (birds, animals, plants etc.) and control light pollution as well control brightness/resultant glare from these installations. It should also not distract vehicle drivers leading to accidents.

Cover Story Media Façades

As technology advances, façade lighting is gradually following the trend of miniaturisation, points out Adagale. New trends include the media façade, which refers to a mode of lighting with the help of which light sources are integrated into the front face of a building. This lighting method borrows from the digital media format of displaying graphics, text and even video images on a building at night, visually transforming its façade after dark. This method is now being recognised as a new field of visual and spatial art that overcomes the structural limitations of rigid architecture. It uses the colours of light to enhance the best features of the building. In short, the architecture of the façade is effectively used as a canvas to display media and digital art on a large scale. LED pixels arranged in a grid are often invisible during the day. They reveal their full capabilities only at night. The small points of light are individually controlled, like the pixels in a TV image. This creates images, videos, animations or extravagant colour patterns. Dramas of light staged in corporate colours create a highly memorable brand identity that is recognisable even from afar. Media façades are increasingly recognised as one of the most exciting lighting technologies for creativity and design in contemporary architecture practice, observes Ar. Prem Nath. When designing media façades, opportunities to push the boundaries are myriad, encouraging lighting designers and architects to embrace this new ‘language’ and explore the use of light and media as façade ‘materials’ to form an integral part of an architectural vision. For this, graphic lights and kinetic lights are synchronised with spatial light animation and fibre optics. Interactive façade is also quite trending – for instance, a robotic video camera randomly captures the surrounding landscape and people, which are then displayed in bitmap graphics onto the building façade; or a building façade which changes the colour distribution according to current weather conditions.

USE OF FAÇADE LIGHTING AS A MARKETING FACTOR Contemporary lighting solutions for building façades need to create added value for local authorities or should have architectural or economic merit by making a location more beautiful and safer, showing a building off in the right light or getting a positive corporate image across. The lighting shall not only generate the revenue for the owners and inhabitants but also do a job of word of mouth as an intense marketing tool for the building, points out Surve. Kanchwala too observes that façade lighting shapes the image of a townscape, attracts attention from large numbers of customers. This boosts revenues and enhances prestige. Lights on a façade are visible to motorists far and wide. Visual memory is more lasting. Façade lighting, says Aneja, is a great way to convey a message, to display the vision of a city, to build a brand. The display of the logo of a

WFM | JUL - AUG 2019

corporate is enough to landmark its headquarter. It attracts employees and customers. Lighting on a façade for a developer may make or break his image. This also helps the developer attract investors. The hospitality industry makes the most of façade lighting where they make it attractive for customers and tourists. Façade lightings not only enhances the value/glamour of a city but also acts as large billboards shouting out outdoing each other, observes Ar. Kembhavi. Adagale adds that façade lighting creates added cultural value. Animated façades of today are used as ambassadors. Many of them even support interaction. A media façade is in harmony with its setting if it embraces both the architecture and people who live in its immediately adjacent space. Public acceptance is greater if a media façade is not perceived as out of place. According to Ar. Prem Nath, LED

kinetic lights are highly impacted and dynamic in movement. Façade lighting design can be customised to complement a brand’s aesthetic value expressed in its external architectural design. By doing so, it reflects the brand’s image on the outside, which also blends with the indoor design, explains Shetty. Displaying marketing elements such as a brand logo and incorporating its colours in the façade lighting, lends the structure a voice to communicate with its audience and a personality that creates a visual experience. Thereby making the building identifiable by the brand loyalists while it also attracts and inspires others. Façade lighting on heritage buildings, bridges and monuments make these structures appealing and draw tourists’ attention. Thereby, boosting the economy of the locality and enhancing its emotional and cultural value, adds Shetty.

Cover Story ON FUTURE TRENDS & TECHNOLOGIES IN FAÇADE LIGHTING Professional façade lighting contributes a lot in adding glamour and beauty to various structures. It helps in highlighting the subtle features of the architecture without impairing them. The trends of façade lighting are ever-changing. The future will see light and architecture as one, with boundaries diffused, and surfaces and materials becoming luminescent, notes Issar. Aneja anticipates the integration of lighting with the government’s security systems in the future. Many crimes and thefts can be prevented when lights from a façade signal to the police control room or security services are alerted when a citizen is in distress. Studying the traffic flow is another field where the lighting on façades can gather data and send it to a processing centre, she adds. Lighting on façades can act as a data routing medium from satellites. The possibilities are many and we are heading there very soon! Ar. Kembhavi observes that the façade design is transiting from staid static to responsive dynamic, getting responsive and communicative to a situation/ environment. Future technologies would involve façade that is selfcleaning and information sensitive. However, the biggest challenge shall be to balance the cost to performance ratio. Cutting edge technological advancement is leading to the generation of façade design that is responsive to the environment changing dynamically with weather and seasons aligning with nature nurturing a green ambient environment and is constantly evolving. Future façade can be defined as fully responsive parametric façade that is nonstatic, but kinetic addressing varied issues including sustainability, power generation, vertical

farming and are informative and transformational, adds Kembhavi. Surve and Adgale predict that ‘Projection Mapping’ is going to be in demand in the future. At present, the knowhow is limited, there are very few manufacturers, the cost is exorbitantly very high, the equipments are very large and needs lots of space for the installation and so on, says Suvre. Adagale foresees that projection mapping (the process of projecting an image or video on the contours of a façade to create stunning effects) and GOBO projection can be seen in the façades of the future. GOBO stands for “Go Between”. It is basically a stencil or a cutout which is placed in between the lamp and the area to be lit. It results in artistic shadow and light effect creating stunning effects. According to Shetty, a technology that facilitates smart lighting management will become a routine feature in all outdoor lighting designs in the near future. The smart-home technology will become widely preferred with the growth of automated controlbased sensors and machinelearning technology. Using façade lighting to communicate with the audience through text, images

and animations projected on controllable LED pixels on the façade will become bigger and more enriched marketing medium. CONCLUSION Illuminated façades facilitate orientation, convey messages, communicate emotions and create attention. Contemporary lighting solutions for building façades need to create added value for clients/owners/builders/ local authorities and it should deliver architectural and economic merit by making a location more beautiful and safer, showing a building off in the right light or getting a positive image across. Nowadays, lighting solutions also need to be sustainable, energy/ resource conserving and prevent unnecessary light pollution. A creatively illuminated building becomes a landmark and markets itself without any extra effort and it helps in branding too. Cutting edge technological advancement will lead the façades of the future to a different level, as a communicating visual experience. Achieving these goals demand great aesthetic design sensibility.

Cover Story applications like water fountains, etc. Please list a few checkpoints to consider for best façade lighting solutions, especially for monuments. Façade lighting needs an indepth study of a site as well as the surroundings. The foreground lighting and background lighting are to be analysed as it will decide the total number of fixtures, wattage, etc. so that the other lighting fixtures don’t overpower the monument. Mounting of fixtures is also important as nobody would like to see the fixtures on the facia of a monument in broad daylight, the beauty lies when you

don’t see the fixture in the day but wonder where the light is coming from, which is enhancing the beauty of the monument. We are blessed to have numerous old monuments, forts, temples, etc. but we have to keep in mind the civil structure is not at the receiving end while we fix up the light fixtures. Wiring conduits for RGB fixtures is also important, so the cable path is to be defined wherein our expert execution team applies planning and balance out each aspect beautifully. Please throw some light on the standards, local norms and regulations for outdoor lighting. Lighting up a monument is far

more difficult than modern-day architectural marvel, for which we can make provisions for installation, wiring, etc. But in old monuments, it is difficult. So, our first mandate is to retain the daytime visual delight of an admirer, at the same time, providing a clutter-free, almost invisible installation and mounting. In a low foreground and low background light, 15 lux is also quite pleasing, wherein a business centre, the value can be 5-8 times. Lesser sky pollution or stray light is always welcome, wherein our special façade application optics ups the ante by controlling light and illuminating the target area only. And one such example is Humayun’s Tomb wherein

Cover Story 4.5-degree beam angle helped us in highlighting the upper portion and dome of the monument precisely. How can we use façade lighting as a marketing factor? Big corporate houses are using the colour based theme light in sync with their logo - a mandate in their building and premises. With the RGB lighting, which offers 16.4 million colour combination, the same colour effect could be produced with matching theme of any company, which is an extension to their branding in a different vertical. Earlier, people were using the colour diffusers and

tube lights, but now with LEDs, they can also reciprocate other social sentiments and emotions, for e.g. tri-colour theme on 26th January and 15th August, world cancer awareness day, women’s day, etc. Festive moods could also be reflected beautifully like red & white theme on Christmas, green and white theme on Eid, colourful canvas on Holi and Diwali, etc. It is important to go for sustainable façade lighting having responsibility for nature, resources and the environment. How can we achieve this? Vertical plane illumination can

go wrong if wrong optics are selected, and it would result in light pollution i.e. stray lights, skyglow, etc. So we apply sustainable and nature-friendly lighting. We do not disturb the ecological balance of birds, animals and other creatures while illuminating a monument. The LEDs used are with RoHS compliance as well as complying with the eye safety standards. Most of the products are made up of aluminium, which is recyclable and energy-efficient due to excellent electronic drivers. These fixtures can be dimmed down and controlled from remote locations with the help of an integrated wireless control system.

Ar. Mahesh is a recipient of more than two dozen awards & honours. A trendsetter in conceptualising building designs, he is a ‘professional architect’ as well as a proven ‘academician’. It is this virtue that dominates his personality as a ‘Man of Institution’. Ar. Mahesh has also founded the College of Architecture Trivandrum (CAT), which is one of the most acclaimed schools of architecture in the country today. In a conversation with WFM, Ar. Mahesh talks about his practice, inspirations, design approach and his milestone projects.

lease tell us about your practice? I started my architectural practice in 1976, i.e., 43 years back, the firm has designed a wide variety of projects ranging from a small “Home” to “5 Star Hotels”. Perhaps some of the largest, the tallest and

longest buildings in Kerala at one time were designed by my firm Iyer & Mahesh. I had two short stints as a lecturer in architecture at the College of Engineering, Trivandrum and two years I worked with eminent architect Charles Correa. The chance to work with Charles Correa in 1974 became a

reality when my best friend and mentor Ar. Gopakumar decided to leave Charles Correa (where he was a site architect) and started his own practice in 1974. At Ar. Gopa’s recommendation, Charles Correa appointed me as site architect of the iconic ITDC Ashoka Hotel at Kovalam.

his massive 1.20 million Sq ft building with a twolevel car park and the podium is considered to be one of the ‘finest’ and ‘largest’ buildings in Kerala. The two towers facing each other are ‘V’ in the plan and the solar “shading” is achieved by sloping the façade. The DGU, using lowE-glass, ensures the reduction of heat load and thereby reduces

air-conditioning tonnage. The profusely landscaped podium

adds to absorption of incident heat on the podium.

he research block is a 6-level modern, sleek structure which is planned to house at least 300 biotechnology researchers in a spacious and well-appointed laboratory environment. This technological building faces south-east and northwest, and solar penetration and heat gain are controlled by the use of vertical aluminium fins, which are rotatable. As per the solar study, the incident sunlight on the large glazed windows will be reduced by 80 percent. The U-value, therefore, is expected to be less than 1.5.

Moreover, as most of the academic spaces have windows on two sides i.e., exterior and interior courtyard side, there is ample cross ventilation. The central courtyard with an amphitheatre function as ‘lung’ of the building.

he clean minimalistic façade of the hotel is achieved by the geometric configuration of windows. The two towers have 160 guest rooms with windows using

DGU. There are G.I. square hollow pipe fenestrations for large windows on the lower floors and these fenestrations effectively isolate direct sun penetration and traffic noise.

I started my practice in 1976 and was in a way lucky to bag most of the big projects in Kerala, especially in Trivandrum, and fortunately had a quantum jump in practice as I was the only practicing professional architect with base in Trivandrum. What inspired you to become an architect? We are a family of designers and architects starting from my paternal great grant parent - popularly called School of Arts Narayana Iyer, and my paternal uncle Ar. M. Ramaswamy Iyer, who was the Chief Architect of state PWD, my cousin and eminent Architect Ar. G. Viswanathan and now my nephew Prayag (Chinnu) is a budding Architect. Probably it is family “Gene” combined with “Inspiration”. Could you please talk about a few of your ongoing projects? It will take a full day to talk of the thousands of projects and millions of square feet of buildings which I designed during the last 43 years. Ever since the year 1995, we at Iyer & Mahesh are mostly in ‘hotels &

A coffee table book called ‘Amazing Timber Resorts’ was published in 2013 which today has become a reference book for young architects

How did you get to design timber structures? My domain knowledge and skill in designing timber buildings started in 1995. I realised that ‘green’ or ‘legal’ timber sourced through scientifically correct re-forestation is a very envirofriendly concept. I decided that I will spearhead a nationwide trend to design and build ‘organic’ buildings by using seasoned softwood or hardwood that used ‘Green’ rated timber. Starting from the Poovar Island Resort in 1997 to Tamara Kodai in 2017, we at Iyer & Mahesh designed at least 21 resort hotels using ‘Green’ timber. A coffee table book called ‘Amazing Timber Resorts’ was published in 2013 which has become a reference book for young architects today.

There is an eight-storied triangular ‘atrium’ with a glass roof on a space frame and this eight-storied atrium space will be landscaped and used as an interactive space for scientists. This building is in the planning stage and the structure is supposed to be completed by 2023.

his ‘Smart’ building designed for start-ups and incubating firms have fully glazed façade with vertical fins which drastically reduce the solar penetration. The structural glazing is done with DGU and low-E-glass. The ‘central core’ configuration of the plan allows daylight from all four sides and this planning concept enables all the office workstations to enjoy daylight.

NABARD Regional Office building at Trivandrum

his building designed in 1990 is considered to be one of the most modern ‘cubism’ architectures with features that enable energy saving on structural glazing. As can be seen in the picture, the master roof which covers the ‘split level’ garden terraces totally prevent incident solar penetration on its East façade until afternoon. The building therefore did not require DGU or low-Eglass.

Façades and cladding industries in India have gone through a sea change in the past decade. Tell us about the latest in façade & cladding material and technologies available in the Indian market and those used in your projects? There is innumerable innovation in façade & fenestrations, but most of these are imported technologies and systems. This is a sad situation and because of the exorbitant cost, only high budgeted buildings built by large corporate clients can afford these technologies. I would like to see a day when all these façade systems are entirely built with ‘made in India’ hardware and specialised glass products. What are the key factors to consider while designing and installing façades & fenestration systems? Naturally, ‘natural light’ and ‘natural ventilation’! The other major factors are solar heat gain and ultimately the ideal U-value. Please brief on the technical benefits of a well-managed façade and how it helps the building to be energy-efficient, at the same time could provide a better interior environment? Achieving ‘U-value’ intermission is the key parameter for a wellmanaged façade. Normal annulled glazing in a façade has approx. U-value 3.0 to 4.0, but for achieving the manageable level of comfort and economy in airconditioning, the U-value of 3.5 has to be brought down to approx. 1.5 or even lower. What are your views on future façades & fenestration technologies, and materials? For Indian condition, I suggest a very deep roof overhang or extended chajjas and vertical louver elements as the key systems.

According to you, what is an intelligent façade? How can intelligent façades bring in the greenhouse effect and also restricting intensive use of air conditioners? What about sustainability and environmental considerations when choosing the façade/cladding material? One of the sad things is that in India is that we do not have a proven agency which can design and execute a ‘façade integrated solar energy system’. Another problem in India is that we do not have a proven agency which can design a ‘solar energy integrated façade’. If more and more buildings have to be “innovative” in reducing energy consumption, façade integrated solar energy system has to be available. What is your advice to young, aspiring architects? The young architects today are not studying climatology and solar penetration. These architects, as well as the experienced architects, need to hire a specialist façade engineering consultant for bigger projects unless they are capable of preparing detailed engineering drawings for complicated and large area façades.

Industry Speaks

lease tell us about your company Virgo Laminate Group and yourself? How long you have been in this business and in the Indian market? I am one of the directors of Virgo Group. As a group, we are not only into manufacturing of laminates, we have six divisions - laminate, plywood, aluminium sheets, ACP, PVC, and the last and the most recent one, the pharma, where we produce IV fluid, cough syrup and liquid injections. I am personally in this business for the last 12 years. We are in the Indian market for the past 27 years. Pan India, we have a total of 9 plants. Three of our plants are in Dera Bassi in Punjab; two are in Kala Amb, Himachal; one in Hoshiarpur, Punjab; one in Bhiwadi, Rajasthan. In the west, we have a plant in Ahmedabad and in the south, we have one in Hindupur, Andhra Pradesh. In total, we have 24 lines for making laminates. After the installation of all the lines in our plants to their full capacity, we will be Asiaâ&#x20AC;&#x2122;s largest producers of laminates. Also, we are among the top manufacturers of aluminium from more than a decade. As per our present data, we are associated with over 12,000 dealers. We are trying to increase the transactions with them, which is our first motive. The second motive is to increase the number of distributors in tier two and tier three cities. These will surely increase the volume of our sales. We are planning to penetrate into the rural areas, where the demand for laminates and the ACP is increasing since these products are no more considered as luxury products. ACP is being used even in small-scale shops in rural areas since they are the best and cheapest alternative, at the same time long-lasting. ACP is being used in signage too. In rural areas, since there are not

104

WFM | JUL - AUG 2019

many options, there is not much of price negotiation too. Till now we have about 36 branches in India, including ACP. This will help the easy availability of our products, even in Tier 2 and 3 cities, where the demand is much higher. Markets in Tier 1 cities are very competitive, where we find plenty of price war. We are increasing our volume to cater to this demand. We have four warehouses outside India, which are in Thailand, Malaysia, and Singapore. About 25% of laminates, 30% of aluminium, 5% of ACP and 30% of pharma produced are exported. We are targeting our exports to grow manifold in the next couple of years. Tell us briefly about your journey with the company over the years? We started the company in 1993 and our first plant was for plywood. It took some time to understand the market and capture it. Then we found that there is a big scope for the laminate industry, we set up our second factory, the first

one for laminates, in 2000. The consumption of the market was very high at that time and there were very few competitors. In 2006, we opened a very big plant in Himachal. We got around 5 lines in Himachal. We were doing very well, and we felt the need to diversify our business. In 2010, we started the aluminium business, and presently we are the largest producer of aluminium roll sheet product, which is used in manufacturing chequered plates (used in the flooring of buses, buildings etc.), aluminium foil for food packing, fan blades (which we are supplying to big companies like Usha, Bajaj, Havells), car engine heat shields, radiator/ AC fins, bottle caps, LED lights, etc. Aluminium was a completely different line and market. But we did very well. It took 6 years to settle down. There are only 4 companies in India which produce aluminium roll products. Then in 2015, we opened a new factory for laminates at Bhiwadi in Rajasthan. We got 4 lines there. It helped us

to reduce the freight cost and to capture the middle and west India markets. Then we opened another factory for laminates in Hindupur, Andhra Pradesh. This helped us to capture the markets in the south. The last and the biggest factory opened in Ahmedabad in about 55 acres, where we manufacture ACP. We will start producing aluminium and laminates in the next 6 months. The Mundra port is very nearby and we will start exporting from there soon. We are the second-largest producer of aluminium roll products in India. We got very good clients in the USA, UK, Australia and Dubai. For laminates, we want to expand outside India, and we are already exporting to Thailand, Singapore and Malaysia. We are planning to export it to Dubai, the USA and the Netherlands. We took over of the pharma business last year and it is a different division altogether. And it is a new business for us. What are the exterior cladding product categories offered by

106

WFM | JUL - AUG 2019

Virgo Industries? We manufacture three types of cladding materials: 1. HPL laminates, 2. ACP and 3. Solid aluminium sheets. We are among only a few companies in the world that can provide all three solutions for building façades. While we are doing a lot of innovation in ACP, we are also keeping our focus on HPL laminate cladding and solid aluminium. Every product has its own market and its own customers. We are therefore ready to meet the expectation of façade consultants, architects and customers by fulfilling their façade dream by supplying the right product. In ACP, we are having the most advance A2 Grade along with other grades of FR Category ACP. We have done a lot of innovation in colours and designs in the ACP market in India. In fact, our new production line of ACP is only of its kind in India. We have recently launched wooden collection inspired by designers from Singapore. Similarly, for HPL cladding laminates, we don’t need any

introduction as we are the largest producer of laminates in India. Our expertise in this product is unmatchable. Also, solid aluminium panel is the new development for façade. We are making aluminium products for more than a decade. And we are proud to say that we are the only company in façade business that has its own aluminium making capacities. Throw some light on your company facilities and structure? Right now we have over 4000 employees, including labourers. Structure wise, we are adopting the lead-based system for business and are upgrading ourselves. Even we are going for SAP right now. Regarding the facilities for employees, we are giving many plusses like medical insurance and other benefits. We give free food to almost all our employees. We have a few landmark training programmes for our employees. Also, we organise motivational seminars for our key employees. We send many of them abroad and within India for such seminars and training, which are definitely adding value to our company. In our organisation, everyone works like a family and all of us drive forward for a common goal. How do you see your business evolving? We are Asia’s largest manufacturer of laminates with the sales of more than 14 lacs sheet per month. As mentioned earlier, we have doubled up our production capacities and our target is to become the top player in the world laminate industry. With the new Ahmedabad plan, our aluminium sheet production will also double up and our total production figures will grow up by 7500 tonnes per month. Similarly, in ACP, we have the latest technologies in place. We are

Industry Speaks

Aggarwal Hotels, Kota, Rajasthan

having the best and most modern technologies to produce the ACP sheets of international quality standards. While there is a lot of demand for FR Grade ACP. We have got our products also certified from Exova, Warrington Fire, UK. We are observing that the focus of the country is increasing towards infrastructure and as a building material producer, we see a lot of opportunity in the future. Virgo is a manufacturing company with a distinct and dedicated vision. It believes in churning out products that not just withstand stringiest of quality measurements, but also delight and surprise its customers with their sheer perfection in making. What has been your or your organisation’s contribution to bringing about the current revolution in the façade cladding and the fenestration sector? We have always been a pioneer

Sobha Global Mall, Bengaluru

Empire Greens, Jodhpur

in terms of technology and innovation. Since our entry into façade segment, we have always promoted the most advanced products. Since our launch in ACP, we have focussed on FR Grade ACP. Not only this, we have invested in A2 manufacturing facilities at a time when people have very less information about the same. We continuously focus to educate industry about the latest technology innovations in façade. We believe that technologies like A2 FR Grade will bring the new revolutionary change in the whole façade industry. Also, the solid aluminium panels are one of the new revolutions in this industry. We are working on this product to make it more easy and usable for façade consultants and architects. Cladding Industry is not just about the production, but about the protection of the environment also. Aluminium is 100 percent recyclable. There is no damage to the earth caused by the product. Almost 80 per cent of the aluminium product manufactured are recycled and reused. In ACPs, we promote FR ACP and A2 ACP – both are fireproof/ fire resistant and are UK certified products. In many countries, it is mandatory to go for A2 ACP.

Please tell us about a few of your iconic and innovative projects? We have done over 1500 projects including commercial, hospitality, residential, institutional, retail, office, healthcare and many government projects across India. Some of our recent projects are the legislative building in Srinagar, the Terminal 2 at the Delhi airport, the railway stations in Amritsar and Mugalsarai, and many residential projects in Punjab, UP and Haryana. We are also doing all the signage for Samsung and MI phones. The biggest mall in India at Bengaluru, by Sobha Builders, is done by us with over 80,000 sq m of ACP applied. There are many more institutional, hospital and commercial projects to mention. Also, we are doing many FR Grade ACP projects, solid aluminium

panel projects and HPL cladding projects throughout the country. As per your view, how important is the role of right cladding in achieving system performance, optimum acoustic and thermal insulation as well as in achieving the desired aesthetics? Most of the properties, like thermal insulation or acoustic performance, are same whether you are using aluminium, ACP or HPL. There is not much difference. There are a lot of incidences

of ACP flying off or falling off and causing damage during heavy winds. Will the aluminium cladding help in this case? It all depends on the fabrication part of ACP. If it is not done in the right way, (if it is not fitted well on aluminium sections) ACP cannot withstand wind pressure and it falls off. To save some money, people go for low-quality ACP and aluminium profile. One should go for qualified and certified products. I believe, if you will not use the right product with the right quality and right specifications, you will not be able to achieve the system performance you are expecting. This applies to everything from the alloy of aluminium used to the kind of adhesives matters for making the right product. The cladding material is the most important of any faรงade system, if your product is not

How well aware do you think are the decision-makers like architects and builders about the availability of the cladding products, its functionality and categories? Architects are well aware of the latest materials and they are doing a very good job by changing the face of the cityscapes. But sometimes, there are some wrong notions. For example, people have stopped using ACP and have migrated to HPL, though both the products are equally good. Yes, some products of ACP got faded out. But this would happen if one is using cheap, low-quality material. When one goes for PE grade or PU grade, there is no warranty, it could fade in a few years. We are producing 100 per cent PVDF and we give 15 year warranty on our products. For HPL, we give 10 to 15 years warranty. The thickness of aluminium should be specified in the ACP. In some high-end projects, even with the best architect and the builder, if the aluminium cladding used is not of the right thickness, then the quality will get affected. If the budget is reduced, then the supplier will supply lowquality material. The thickness of aluminium is important. So the use of material varies from project to project based on the budget. In places like Ahmedabad, some buildings have used very high-quality materials which can be compared to high-end

projects in Europe. They are using aluminium sheets for cladding in a very innovative way, applying perforated cladding on faรงades, designed and made using CNC machines. I think the architects, builders and faรงade consultants are very much aware and focussed on choosing the right product. But the implementation has to be controlled and checked. We should promote the right product and

right specifications. Also the focus needs to be increased on whether the right product has been used or not. Since there are so many suppliers, and in this competition inferior quality material is being used at times, that gives a bad name to both the organisation and product category as well. What is the emphasis laid on R&D, especially for the Indian market? We are investing a lot in R&D. We are getting a number of experts from Germany to train our employees in India. China too is good in technology, and we are open to adopting any new technology in order to improve the quality of the product. They come to our factory, and train our experts on the latest in technology and share with us the latest in technology. In ACP, we are doing anti-fading treatments with some chemicals, which we learnt through such training. We do R&D day and night for the betterment of products and for the better future of our country. Our products are premium in quality and one need not go for imported products at all. In a few months, we will be providing the entire aluminium sheet systems for wall cladding. The aluminium profiles needed would be imported and our systems would be foolproof systems with technology from Germany.

What do you see as the main challenges faced by the cladding industry? The main challenges are competition, a reduced price of products and low-quality products. The products specified are not supplied as per specifications and due to this the companies making good product have to face the heat. Also, the strict rules and

Tell us about your channel expansion strategies in the market? We are expanding our business to tier 2 and tier 3 cities through dealers and distributors.

We always provide our customers with the best of the products at a very reasonable price. Our USP is the service. We provide the best possible one.

large amount and time on faรงades. Earlier, this was of the last priority. Every company is fighting for a good and innovative faรงade for their building. I feel that every firm should have a separate team for faรงade only. The penetration of the products in the market has improved. With the ACP or aluminium cladding, the building looks like a seamless building. With the government focus on infrastructure and users focus on best of faรงade, we see a lot of opportunity for us.

Owing to the multi-chambered design and the high wall thickness the ÖKOTECH profiles are sturdy and tough. Additionally, the extrawide reinforcement makes them unbreakable and helps bear high wind loads as well.

A flexible range, it allows windows to be tilted inwards enabling safe and secure ventilation. Further, as it does not have any glazing bars or mullions to block the view, these profiles are ideal for customers looking for an expansive view. Further, as it works more like a side-hinged casement window, maintenance especially cleaning of the outer glass is easy. The collection also has a made-toorder option. Arch window profiles are uniquely configured for arch windows and comes with customized reinforcement.

indows are a dialogue - an interaction b e t w e e n elements sometimes complementary and sometimes divergent. Windows are a way of deciding the language the dialogue should have, also the intonation, and that is really what sets the mood. Every project which creates a habitable space is constantly addressing the making of fenestration. It is the underlying dialogue which is created between the inside and outside, between the built and unbuilt.

Often there are certain features of design elements which are generalised and passive across different typologies of the built environment, however, windows are design elements that are heavily influenced by multiple factors like, heat, light, orientation and material. Most of these factors come into play simultaneously when it comes to the design of windows. These are to some extent standardised in case of certain building types such as commercial spaces, offices and institutions, in the case of residences, windows can take on an entirely different

Bedroom - before renovation

meaning. The selection of window types can be eclectic as in a residence design since there are almost no rules and one can respond completely to the honest requirement of the space or can be extremely particular to the usage at that location. It is this lack of rules that make it more interesting to study the windows in residences. If one were to break down the design of openings, the sound knowledge of materials is the first tool that needs to be mastered when it comes to the design of windows. Since they are dynamic and literally moving elements, the role of engineering, structure

and the science of movement are intrinsic in the design thinking for windows. This extends to the knowledge of hardware as well. Whether assembled and customdesigned or prefabricated, this knowledge in relation to windows is essential. The unfortunate exercise of making windows airtight to avoid the exchange of air outside to inside is slowly becoming a key factor that could be placed second. While one was able to use traditional materials like wood with ease earlier, these allow for some natural cracks and crevices as they breathe, and changes form and respond to the environment like a living entity. That to a great extent is now desired to be avoided. This is how artificial materials like metal and plastics are fast finding their way into homes. The other very important factor which is increasing impetus toward selecting these materials is us moving away from cutting trees and plants for building. While wood allows for design intervention and customisation right till the architrave that goes around the opening, artificial materials come in standard

sections based on different uses. It is like the assembly of a kit of parts. As it is here to stay, the movement towards curtailing the mixing of environments and creating completely controlled indoor environments is also leading to windows which are, to a great extent, fixed and therefore not allowing too much of the option to open up. Selectively opening and largely fixing windows have created an entirely new language of design. The window frame, which is an essential part of creating an opening, is sometimes giving way to the frameless glazing, which is fast finding its way into homes as well. The advantage is that it gives a close enough simulation of sitting outside or in a verandah with no visual obstruction - This is one of the features of the modern airtight container buildings we are now having to design.

Adlakha Residence

Vasant Kunj, New Delhi

Principle Designers, STUDIO 9491

he windows were a key design tool for this renovation project of an existing government housing scheme apartment in Delhi’s Vasant Kunj area. Each window was created with a story and to fulfill a particular experiential purpose for the inhabitants. The making of each window was done as if it was a painting and the colours were the hard tools we use to make windows with, be it toughened glass, mild steel sections, uPVC or wood. There were no rules of standard sills or lintels and if a window was to be experienced while sitting down, the lintel was pulled down to make it feel like it belonged there. The other important design tool for windows was to create views and a visual connect between certain spaces. So, the windows between the rooms were the most special things in the house. It opened up a whole new way to remain connected as a unit. Even though a house can be a composition of a series of rooms and movement from one to the other, windows were the tool to let the connection remain. The windows inside the house have contributed to giving a lot of depth to the experiences which become layered due to

Odisha’s Krushi Bhawan Shortlisted for World Architecture Festival Award

disha’s Krushi Bhawan has been shortlisted for the World Architecture Festival award 2019. This sustainable architectural building has been selected alongside other iconic structures like International Olympics Council in Lausanne. The distinct vis visual identity of Krushi Bhawan has been derived from regional materials and vernacular narratives expressed in a manner that is responsive to local climate. “We are really happy and proud that Krushi Bhawan has been selected among the best architectures of the world. Krushi Bhawan broke the general public perception of government offices, which are generally dark and dingy with restriction for the general public. The beautiful ambience

of Krushi Bhawan has helped in creating a better work culture for the employees at the same time bridged the distance between government and people,” said Arun Sahoo, Agriculture Minister. The building has a unique ventilation system and a high thermal mass to keep the building naturally cool and make it energyefficient. The façade of the building has a brick-louvered screen that

acts as a solar shading device and expresses itself in the pattern of Ikat weaves, its colours representing the geographical diversity of the region, said sources in Lotus Studio. Along with the Krushi Bhawan, 12 more Indian projects have been shortlisted in the final list of the awards. The World Architectural Festival will be held on the 4-6 December at the RAI Amsterdam.
