Façade Design

Façades: The Interactive Element that Elevates Buildings

Buildings possess the charm to speak to their environment. Their surroundings include other buildings, people, the street, and the place as a whole. Amid the repetitive faces seen in the surrounding structures, a building with a distinct façade catches the eye. It then starts a dialogue between the occupants, the passersby, the rest of the buildings, and the street, and becomes a landmark in itself.

Pentaspace Design Studio, an architecture and design firm in Mumbai, creates distinct façade designs that become landmarks in the town. Gaurav Sanghavi and Harsh Pote, Partners, speak of a few of their projects that define Pentaspace’s distinct signature.

FAÇADE AS AN INTERACTIVE MEDIUM

Nestled in the heart of the city lies a stunning architectural masterpiece that captures the essence of the surroundings and creates discourse. Rainforest, a residential complex

located in the Marol area of Mumbai, is situated amidst the lush rainforest trees that offer stunning views of Powai Lake and Aarey Colony. Pentaspace has taken inspiration from nature itself to create a replica of its surrounding landscape that blends seamlessly with its environment

and provides an oasis of calm amidst the hustle-bustle of the city.

The earthy tones used in the façades, landscape elements, and drop-off canopies beautifully reflect the natural beauty of the rainforest. The dropoff areas have been designed as tree canopies, making visitors feel as though they are entering a forest. “We translated the foliage as a design feature and made it an integral part of the design where the architectural language reflects the natural surroundings. More than an acre of land was landscaped on Mother Earth with the theme of the Amazon rainforest,” says Gaurav.

The site of the complex was heavily contoured and the area was covered with dense rainforest trees that had to be retained. The architects had to achieve a balance between retaining the most number of trees on the site and providing a wide vista for the eleven residential towers, so, the buildings were planned in a staggered manner to adapt to the topography.

Capturing the essence of the Amazon rainforest, the complex’s design is aesthetically pleasing and offers residents a unique living experience that is both tranquil and luxurious.

FAÇADE AS A LANDMARK

The Chambers building in Andheri is a marvel of architecture that stands tall and proud in the bustling Chakala commercial area. Its unique form has earned it the title of the ‘Jewel of the suburban business

district’. The diamond-shaped building reaches angularly for the sky, a result of several challenges faced during the design process.

One of the biggest challenges faced by the architects was the oddshaped, curvilinear plot on which the building was to be constructed. Other challenges included the ongoing Metro rail construction along the adjoining road, modifications in municipal

and construction rules, and height restrictions.

The site’s unusual shape posed significant difficulties for the designers, who had to come up with innovative solutions to make the most of the available space. They decided to turn the building elevation diagonally north-west at a 45-degree angle, which opened it up to the busy highway and the surrounding cityscape.

The building, which catches the eye during the day, stands in its full glory in the dark hours as well. The striking LED strip around the edges of the diamond glows brightly in the night sky, making it a shining landmark for the surrounding area and giving a unique identity to the region.

A FAÇADE THAT MERGES WITH THE LOCAL SURROUNDING

The residential project Aroha in Borivali is a perfect example of how architecture and design can be inspired by the rich cultural heritage of a place. The design of the building is inspired by the nearby Kanheri Caves, which have been recognized as a UNESCO World Heritage Site. Pentaspace has integrated aspects of Buddhism into the design, creating a space that is not only aesthetically pleasing but also evocative of the historical significance of the area.

As inhabitants enter, they are greeted by lobbies adorned with carvings depicting the story of Buddha, directly reproduced from the Kanheri Caves. The history and significance of the area are carried into every aspect of the design. These carvings also help to create a sense of continuity between the past and present, reminding visitors of the rich cultural heritage that surrounds them.

Natural stones are used for wall cladding and flooring, which adds to the aesthetic appeal of the building. The long drop-off canopy with cutouts is a unique feature that allows natural light to penetrate through the entire space and emulate Buddha’s teachings. The flooring on the podium level and the landscape area are made of stamped concrete that resembles a cave floor.

“The caves narrate a story, and Aroha has been designed in a way to create a microenvironment for its inhabitants amidst

the concrete jungle by amalgamating the cave architecture features into modern architecture, to inculcate a sense of awareness and curiosity of the heritage grandeur present in the vicinity,” says Harsh.

Rainforest, Chambers, and Aroha show the ways in which buildings become the representation of the locality. The frontage of a building is a crucial element of its architecture; it sets the tone for what is inside and gives passersby a glimpse of what to expect. Pentaspace Design Studio has made this part a focus of their style that leaves an impression on the minds of visitors as well as the whole city.

Façade Design Façade Design - an Important Element for Leveraging the Real Estate Values

It is often said that “Looks do Matter” and this is very true when it comes to the building facades too.

The word ‘façade’ originates from the Italian word “facciata” and it means the exterior or the faces of a building. The façade on any building has 2 main functions. Firstly they act as a barrier or skin that separates the interior face from the external environment and secondly, they create an image of the building. And hence façade design is a very important aspect of a building. Building façade or the skins plays a pivotal role in architecture. They determine the aesthetic appearance of a building, and its relationship with the surrounding context, and they are the interface between the built and human dimensions of our cities. They often dynamically mediate between the indoor and outdoor environments.

With the changing times architecture and façade design have also changed and people are becoming more and more conscious about the environment

they stay and work. Be it their houses/ apartments/workspaces or business premises everything matters to all from children to the youth, to the adults and the old generation.

There is a sense of ownership one carries for their houses and workspaces and the building facades play a crucial role in this. Buildings today are no longer considered boxes or just functional spaces as it is here where people interact, grow, create memories, and live their lives.

The building façade, be it for a residential apartment or a commercial building, is the calling card of the project as it is the most iconic, one of the most aesthetic and recognisable elements which help create an identity of the building. With more and more globalization, a lot of focus has been seen on ESG and Sustainability by various companies, stakeholders & governing bodies. There is a lot of focus on IGBC, USGBC, LEED, WELL, and EDGE certifications of the building where façade design becomes a very crucial element of the building design.

WHY FAÇADES ARE IMPORTANT?

Broadly the façade design should be addressed with the following characteristics.

Adding a Character to a Building:

The building façade could be a derivative of the local architecture, create a new identity of its own or be a result of a climate-responsive design.

Natural Ventilation:

If intelligently designed and executed façade could also help natural ventilation to the buildings and help reduce the ventilation cost and improve the wellbeing of the users. E.g. The Jali’s used in the traditional buildings in Jaipur like Hawa Mahal and the modern-day version of the same can be seen in the PAM centre in Malaysia.

Act as a barrier against the external environment:

The interiors of the building are protected from the rain/sun/wind. There are buildings which have smart façades where the façade as a whole or some elements such as fins and shades move or rotate basis the change in local climate during different times.

Energy Efficiency:

Today when we speak highly of ESG, Human Well-being, and Sustainability, the façade design plays a very important role here. The façade, apart from being aesthetic, also has to address the issue

of energy efficiency. A good climatic responsive façade can help reduce the solar heat gain and reduce cooling requirements thus reducing the HVAC cost in terms of the CAPEX and OPEX. A lot of research has been done on this including biophilic design, Vertical greens, glass selection and other façade elements like sunshades, fins, canopies, and multi-level terraces to increase the energy efficiency of the buildings.

Human Comfort and Wellbeing:

A good climatic responsive and successfully implemented façade has a deep impact on the occupants of the building. Carefully designed façade which allows light and natural ventilation through various design elements such

Façade Design

as louvers, courtyards, terraces, shading devices and automated façade systems that help regulation of the air and light movement through the structure and have a positive impact on the occupants. It impacts their mental well-being and physical well-being too. This in turn results in better productivity and results.

Aesthetics:

While façades are often referred as to the skins, they add an aesthetic appeal to the buildings. Interesting facades with distinctive features, a splash of colours, layers and elements add a lot of visual appeal and appreciation to the building. Buildings with unique features often become local or global landmarks for the way they have been designed and add a lot of value to the structure itself and the neighbourhood too at times.

Extended Life and Value:

Facades which are carefully designed can also influence the life and valuations of the buildings. The use of innovative materials, shading devices, unique systems, sustainable designs and a pop of colours is what brings structures to life and shall help extend the life and value of the building. The extended life and value in terms translates to higher yields for the people associated with the buildings whether they are the developers, the owners, or the occupants.

Today when we see such buildings around us, they bring a sense of pride

Spectrum Apartments – Box Hill, Australia

Bilbao Museum, Guggenheim, Spain

Façade Design

to the developers, consultants, and contractors associated with building these structures, the companies (including local as well as Global MNCs) who buy/lease these and the end user who actually use it on a day-to-

day basis. There are various examples where we see that buildings which have aesthetically pleasing façade easily demand more rents or selling prices with their competitors which are similar in nature. E.g. The World Towers by Lodha developers in Mumbai.

DIFFERENT OPTIONS FOR ENHANCING FACADES:

1. Invest in High-Quality Materials:

Be it a residential or a commercial building, the use of durable and longlasting materials adds life to it. The use of high-quality materials brings a sense of luxury to the buildings. Modern-day buildings use modern technology and materials to create an amazing façade.

E.g. The Guggenheim Museum, Bilbao.

2. Colour, Texture, Pattern:

Adding a splash of colours, certain textures and patterns can make the façade very interesting and create an ever-lasting memory for developers and the occupants of the building. A unified and aesthetically beautiful facade can be achieved by selecting a colour scheme that compliments the architectural design and the surrounding area. Contrarily, the texture gives the exterior depth and intrigue. E.g.: IMI International Management Institute – Kolkata, India & Brandhorst Museum – Munich, Germany.

3. Interesting façade elements:

Various façade elements such as curved walls, fins, and colours can bring drama to the building façade and enhance the building design. e.g. Kuggen Building –Gothenburg, Sweden.

With rapid globalization, the Gen X and Gen Y who are well travelled and who have the world at their fingertips their choices of homes, workplaces and other spaces of interaction are largely and deeply driven by the pointers mentioned above. They should not be referred to “as spoiled for choices” but for “wise decisions” they make. And to conclude “LOOKS DO MATTER”. Kuggen Building – Gothenburg, Sweden

Harmony in Design: Mitigating Urban Light Pollution through Thoughtful Building Glass Façades and Fenestrations

The increase of artificial light at night, contributing to the phenomenon of light pollution, is an escalating concern amid global urban development. Numerous cities now boast a luminous sky visible from considerable distances, showcasing the foremost manifestation of light pollution, characterized by excessive or misdirected artificial light. Light pollution poses significant threats to human health, impacting various physiological and psychological aspects. Exposure to artificial light during the night disrupts circadian rhythms, leading to sleep disturbances and insomnia. The suppression of melatonin production, particularly by blue light emitted from electronic devices and outdoor lighting, contributes to an increased risk of certain health issues, including cancer. Moreover, prolonged exposure to bright artificial light is associated with heightened stress and anxiety levels, potentially

leading to mental health disorders such as depression. The impact extends to ocular health, causing discomfort, eyestrain, and potential vision problems. As a researcher, it is crucial to explore

the specific mechanisms through which light pollution influences human health, citing relevant studies and proposing mitigation strategies. Additionally, acknowledging the indirect effects on wildlife and ecosystems can provide a comprehensive understanding of the broader implications of light pollution. Recent urban development trends have ushered in a surge of artificial light at night, primarily for amenity or security lighting purposes. This surge has substantially transformed the nocturnal landscape & luminosity of urban areas. Light pollution has transcended local boundaries to become a worldwide issue, progressively diminishing the ability to observe stars and instigating a range of environmental and energy challenges. Its components include glare, heightened unnecessary illumination, temporary lighting, and unforeseen fluctuations in lighting levels.

Light pollution has transcended local boundaries to become a worldwide issue

Sustainable Façade Lighting

Diverse sources such as streetlights, fishing boats, buildings, vehicle headlights, and even lights on undersea research vessels collectively contribute to the creation of a domical sky glow, among which reflective building Façades and light through fenestrations are major contributors in urban areas. Additionally, Artificial Light at Night (ALAN) has also been linked to energy wastage, urban heat islands, and, air pollution, further emphasizing the intricate web of consequences associated with excessive night-time illumination. The use of glass in Façade and fenestration design has become increasingly popular in modern architecture due to its aesthetic appeal and functionality. However, the extensive use of glass poses challenges in terms of light management, particularly in urban environments where artificial lighting is prevalent. These contribute to light pollution through various mechanisms, buildings with glass Façades often use exterior lighting for illumination or decoration, which can add to light pollution if not properly controlled or directed; the transparency of glass allows internal lighting to be visible from the exterior, contributing to glare. Glass surfaces can reflect artificial light, amplifying its intensity and contributing to light pollution in surrounding areas. Architects, urban planners, and lighting designers can collaboratively address

and reduce light pollution, specifically in the context of building Façades and fenestrations, through the following strategies:

• Minimizing Decorative Lighting: Controlling and regulating the use of decorative exterior lighting in architectural structures as a means to diminish light pollution can be helpful.

• Directional Lighting Design: Opt for selective and directional lighting that minimizes upward or outward light spillage. Use fixtures with shields or hoods to direct light where it is needed.

• Smart Fenestration Planning: Integrating smart fenestration systems that control the amount of natural and artificial light entering buildings based on time and environmental conditions. Utilizing window films or coatings that reduce glare and limit light reflection into the surrounding environment.

• Selective Glazing: The use of selective glazing materials can help control the amount of light transmitted through windows while reducing reflectance.

• Low-E Coatings: Low-emissivity (Low-E) coatings can be applied to glass surfaces to reduce both heat gain and reflectance, thereby

improving energy efficiency and visual comfort.

• External Shading Devices: External shading devices, such as louvres or overhangs, can be incorporated into Façade design to reduce direct night light penetration and minimize glare for occupants indoors.

• Building Materials: Choose building materials with low reflectance to reduce the scattering of light, and contribute to a darker urban environment during the night.

• Adaptive Lighting Control: Implement advanced lighting control technologies such as dimmers, timers, and motion sensors to regulate artificial lighting levels. Adaptive lighting systems that adjust intensity and colour temperature according to the time of day, occupancy or specific activities.

Architects, urban planners, and lighting designers can collaboratively address and reduce light pollution

The impact of building glass Façades and fenestration design on urban environments extends beyond aesthetics

Sustainable Façade Lighting

The impact of building glass Façades and fenestration design on urban environments extends beyond aesthetics, profoundly influencing light pollution levels and reflectance properties. By employing thoughtful design strategies, architects and urban planners can mitigate light pollution, enhance urban sustainability, and create more liveable cities. Balancing the aesthetic appeal of glass Façades with the need to optimize reflectance is essential for sustainable urban development in the 21st century. The design of building glass Façades and fenestrations significantly influences the quality of urban environments, particularly concerning light pollution and reflectance. Innovative design strategies and technologies empower architects and urban planners to address these issues while crafting sustainable and visually appealing spaces. However, effective light management necessitates a multidisciplinary approach that considers both environmental and human factors. Ongoing research and collaboration are essential to tackle such challenges. The contribution of building Façades to light pollution at night is a significant concern in urban

environments. Exploring strategies to mitigate the adverse effects of illuminated Façades on light pollution is crucial for promoting sustainable urban lighting practices.

How Enabling Information Transparency Can Improve the Value Recovery of Façades

The building industry is materialintensive and has a significant impact on the economy and the environment. It is responsible for approximately 40% of the total waste generated across the European Union (Boorsma et al., 2019). Additionally, façades can account for up to 40% of a building’s total carbon emissions.

The building industry can be regarded as dynamic and highly fragmented in nature. There are many stakeholders involved right from the inception to the End-ofLife (EoL) of the building. The concept of Circular Economy (CE) is heavily debated and interpreted differently by numerous

stakeholders. This suggests that while the concept of Circular Economy (CE) is wellestablished in theory, it lacks a transparent framework which can be translated into practice.

The core idea of CE can be simply translated into three fundamental strategies towards the cycling of resources.

l Slowing resource loops: extending the service life of a product through the application of strategies such as reuse, recycle and remanufacture.

l Closing resource loops: recycling bridges the loop between post-use and production leading to a circular flow of resources.

l Resource efficiency: narrowing resource flows with a goal of using fewer resources per product.

In the contemporary discourse, digital technology is increasingly recognised as a pivotal force fostering the seamless exchange of information among stakeholders throughout the value chain, serving as catalysts for the adoption of circular business models. The enhanced transparency and improved quality of information can boost decision-making processes to improve the value recovery of façade (building) components. Ultimately the implementation of circular strategies hinges on effective management of

Sustainable Façade Solutions

resources, highlighting the integral role of digital technology in shaping sustainable practices.

Several digital innovations have emerged to support circular strategies in the built environment namely, material passports (MPs), Building Information Modelling (BIM). This has sparked the initiation of numerous funded projects such as BAMB and Platforms such as Madaster. They are leading the way in developing, testing, and promoting the use of material passports while also emphasising Reversible Building Design. The former will offer data regarding manufacturing processes, packaging, handling, and warranties, guiding manufacturers in implementing appropriate strategies at the end of the product’s lifecycle. Meanwhile, the latter will assist in disassembling and reusing building components. Additionally, Blockchain technologies, the Internet of Things (IoT), and Façade as a Service (FaaS) are other enabling technologies that have the potential to streamline the transfer of information among stakeholders.

Despite our awareness of viable solutions that could propel us to achieving a circular economy, the question persists: What are the current challenges and how does this shape our current design process? To answer the posed question, the following iterative concepts are explored: (1) Challenges with existing buildings (2) Lack of product data is one of the biggest inhibitors (3) Material passports and their role in implementing circular economy (4) Our Current design process must address these challenges in our new designs.

CHALLENGES ASSOCIATED WITH EXISTING BUILDINGS AND ASSETS

General challenges related to conducting technical assessments on the existing façade systems include:

l Limited or no information available on the original façade manufacturer

l Limited as-built information

l Most of the façade components have reached their End of Life (EoL)

l Challenges in coordination between

various stakeholders of the value chain to disassemble the existing façade.

Challenges associated with the reuse of façade components include:

l Reduced strength

l Limited as-built information

l Potential non-compliance with current regulations

l Uncertain strategy to procure warranties due to varied approaches to residual service life (e.g., glass, perimeter seals, gaskets, etc).

Some of these challenges can be overcome by testing, validations, and or modelling to establish the baseline performance. However, these processes are often time-consuming and reliant on assumptions derived from limited existing information, thereby introducing uncertainty and commercial risk.

LACK OF PRODUCT DATA –A KEY OBSTACLE

As mentioned in the previous section, lack of product data is a key obstacle

to reuse, repair and remanufacture the product. Notably, one significant difference between building products and general consumer products is the short ownership period compared to the product’s service life.

Consequently, original manufacturers lose control over the building products post-installation, with repairs typically handled by third parties who lack manufacturer status. This results in a knowledge gap, leaving manufacturers unaware of product drawbacks. At the product’s End of Life (EoL), a third party steps in to recover residual value, yet pertinent information such as packaging instructions, disassembly procedures, and maintenance documentation is often absent.

This communication gap poses challenges for disassembly and recovery, rendering repair and reuse unfavourable options. The industry’s initial step toward resolution involves integrating material passports into Building Information Modelling (BIM)

Figure 2 –Ramboll’s area of focus for crafting sustainable solutions

Sustainable Façade Solutions

models, thereby transforming existing buildings as material banks.

MATERIAL PASSPORTS

As defined by (Bokkinga,2018), “a Material passport (MPs) is a digital database with valuable information on materials,

elements and components present in the building”. Its range is classified into different levels namely materials, components, products and systems that are present in the building.

The concept of Material passport is increasingly being recognised as a crucial component within the construction industry as an integrated information system which will bridge the gap between physical materials and digital databases. They contain information on lifecycle management that can be used to recover a product at its EoL thereby reducing waste generation, pollution, and decreased landfill. This quality makes them crucial in steering the construction industry towards a circular value chain.

The advanced tracking features of MPs provide immediate information on location and material properties highlighting the risks associated and promoting sustainable recovery.

to counteract ambient noise, present effective means of enhancing acoustic comfort in buildings. Proper sealing and weather stripping of a building ensures components ensure airtightness, further mitigating the ingress of external noise.

By embracing the latest advancements in acoustic design, architects and designers can fashion spaces that not only captivate the eye but also provide solace to the soul, offering a refuge of tranquillity amidst the urban commotion.

UNDERSTANDING ACOUSTIC DYNAMICS IN BUILDINGS

Before delving into the specifics of façade materials and installation techniques, it is imperative to comprehend the fundamental principles governing acoustics within buildings. Such comprehension is essential for crafting spaces that prioritize comfort and productivity. Acoustics in buildings pertain to the behaviour of sound waves within enclosed spaces, influenced by diverse factors such as architectural layout, material selection, and activities conducted within.

External sources of noise, including traffic, construction, and urban development, pose significant challenges to indoor environments. These noises can permeate buildings through windows, walls, and doors, disrupting concentration, communication, and overall comfort. Additionally, factors such as proximity to highways or industrial zones can exacerbate noise levels, impacting the quality of life for occupants.

Internally generated noise, encompassing HVAC systems, mechanical equipment, and human activities, further contributes to the acoustic dynamics within buildings. Inadequately insulated walls, floors, and ceilings can facilitate noise reverberation and echo, creating discomfort and distraction for occupants. Moreover, open-plan layouts, while fostering collaboration, can also lead to elevated noise levels if not properly managed.

Façade Materials

Architectural design assumes a crucial role in mitigating the impact of both external and internal noise sources. Strategic placement of rooms, corridors, and building elements can minimize noise transmission and optimize sound quality within different areas of a building. Additionally, the selection of appropriate materials endowed with sound-absorbing properties is vital for controlling reverberation and enhancing acoustics.

Materials such as acoustic insulation panels, mass-loaded vinyl, and doubleglazed windows are commonly employed to ameliorate sound insulation and reduce noise transmission. These materials absorb sound waves, preventing them from bouncing off surfaces and causing

reverberation. Green façades, integrating vegetation on building exteriors, can also function as natural sound barriers, thereby further enhancing acoustic comfort.

Advanced installation technologies, such as decoupling systems and active noise control, offer additional tools for managing acoustic dynamics in buildings. Decoupling techniques entail isolating building elements to minimize sound transmission between them, while active noise control systems utilize sensors and speakers to detect and counteract ambient noise in real time.

In conclusion, comprehending acoustic dynamics in buildings is crucial for creating environments that promote wellbeing and productivity. By addressing

Understanding the Variations in Test Regimes for Compartmentation & Spandrel Protection Systems in Curtain Walls

CCurtain walls have been shaping the visual identity of modern buildings since the late 19th century, especially for sky-high multi-occupancy structures. However, design and safety standards have evolved - and so have the passive fire protection measures employed to safeguard the lives of those using these buildings.

To protect these properties effectively in a fire, it is vital to ensure that compartmentation between the floor slab and the façade—an area referred to as the spandrel zone— is robust. However, there are many different passive fire protection products on the market that have been tested to different standards or combinations thereof. It is important that designers, specifiers, and fire engineers appreciate the variances in the scope of these tests for a more

holistic understanding of the firestopping measures installed within the spandrel zone and to ensure the highest levels of fire safety are achieved.

GOING BEYOND PRODUCT

To prevent fire spread through the movement joint, there must be a continuation of fire resistance of the compartment floor right up to the façade using perimeter firestopping measures. Many codes and regulations around the world make provision for this, demanding the use of slab-edge fire seals that have had their fire resistance certified to different product test standards. However, the test paths to compliance offered can vary hugely in scope, and the types of curtain walling systems they can apply to.

For example, in the UK, the legacy path is to use BS 476-20: 1987 - Fire tests on

building materials and structures. Method for determination of the fire resistance of elements of construction (general principles). This is a small-scale, static test that requires a specimen to be installed between two concrete lintels within a furnace and subjected to defined heating and pressure conditions. Whilst BS 476-20 can provide a basic understanding of a product’s standalone performance, the test is designed to be generalised and therefore cannot give a clear indication of a perimeter fire seal’s ability to resist fire in its intended application. EN 1366-4 - Fire resistance tests for service installations - Part 4: Linear joint seals is a test method similar to that of BS 476-20. However, in 2021 it was amended to exclude curtain walling perimeter seals from its scope.

As anyone who works in fire safety knows, it is often not the performance of

individual products that determine how fire will spread, but the combination of all the materials, elements and how they have been assembled. Whilst perimeter firestops are highly effective at inhibiting fire and smoke spread, compartmentation is reliant on them being able to maintain their fit between the floor slab and façade. This is why many regions look toward standards that offer a much more holistic perspective of the perimeter firestop’s performance in a spandrel construction rather than its performance as a standalone product.

This is particularly important when we consider that most curtain wall systems comprise non-fire rated aluminium framing and non-fire-resistant vision glazing. These are sometimes referred to as ‘Type A’ systems. With a melting point of approximately 660°C, aluminium loses its strength around 350°C. This can result in the framing structure distorting and gaps forming at the wall / slab edge intersection, impacting the perimeter fire barrier. Not only can this open multiple paths for fire, smoke, heat, and gasses to spread upwards internally, but the increased ventilation can also fuel the fire, enabling it to grow in size and ferocity.

To reduce this risk, a high density stone wool fireboard that shields the spandrel panel and the mullions within the spandrel zone can be used alongside the perimeter firestop. This can help to prolong the stability of the assembly, allowing the firestop to fully perform its compartmentation function whilst reducing the chance of the fire breaking through the spandrel panel itself. This approach is common practice in jurisdictions such as the United Arab Emirates and Australia and can be assessed by both European (EN) and American (ASTM) test standards.

EN STANDARDS

EN 1364-4: 2014 – Fire resistance tests for non-load bearing elements (Curtain walling – part configuration) is widely referenced in building codes and regulations in many countries across Europe— including the UK— Middle East and Asia Pacific. It is also the recommended test standard for curtain wall perimeter barriers in the Association for Specialist Fire Protection’s (ASFP) Advisory

Note 7, with CWCT having announced that it proposes updating Technical Note 98 to recommend the test too.

As a ‘part configuration’ test, it looks at the spandrel assembly of a curtain wall system, comprising the mullions, transoms, and infill and spandrel panels. This makes it far more representative of a perimeter firestop in its end use application. It also allows for multidirectional movement which would occur in the event of a fire as different building elements heat up and deform.

It tests individual parts of the assembly such as the perimeter seal or the anchoring attaching the curtain walling to the

Fire Safety

floor slab, or systems with fire resistance requirements only to the spandrel zone. There are specific configurations of the test that can be chosen depending on the primary element that needs to be assessed. In very simplified terms, Configuration 5 is used to assess the ability of the perimeter fire seal to contain the fire inside the compartment, under the stress of temperatures and pressures that lead to in-test deflection of the façade and floor slab. Meanwhile, Configuration 2 tests the upstand and downstand with the perimeter seal and anchoring, or a combination of and is often used by façade manufacturers as it incorporates flaming on both the inside and outside of the

Fire Safety

façade; this configuration would be used by curtain wall system manufacturers for specific data on the façade.

Additionally, to validate the durability of the perimeter firestop, EN 1364-4 also includes provision for long-term façade movement by referring to the European Technical Approval Guidelines 026-3, which is now superseded by European Assessment Document (EAD) 350141-001106. This requires that the perimeter seal is subjected to a minimum of 500 cycles between the minimum and maximum joint width, to simulate in-service wind sway, seismic activity and thermal load at a rate designated by the test applicant 24 hours before fire exposure.

It is important to note that this test and its configurations focuses on the performance of materials and elements just within the spandrel. EN 1364-3: 2014 - Fire resistance tests for non-load bearing elements (Curtain walling – full configuration, complete assembly) on the other hand offers a full configuration test to evaluate the performance of the complete curtain wall assembly and includes any transoms

and mullions, infill panels and the spandrel zone. However, it is only applicable to ‘Type B’ fire-rated systems, which are rare.

ASTM STANDARDS

Another common test standard for perimeter edge fire seals used in USA, UAE, and parts of Asia Pacific (using the international code council’s (ICC) International Building Code (IBC) that takes into consideration the performance of the spandrel) is ASTM E2307, Standard Test Method for Determining Fire Resistance of Perimeter Fire Barriers Using IntermediateScale, Multi-story Test Apparatus.

This measures “the performance of the perimeter fire barrier and its ability to maintain a seal to prevent fire spread during the deflection and deformation of the exterior wall assembly and floor assembly during the fire test.” It uses intermediate scale multi-storey apparatus to better replicate a fully developed curtain wall fire. The perimeter joint and perimeter firestop are exposed to fire from both inside the test room and outside to simulate the room where the fire started, as the fire plume exits the room of fire origin

through a window opening and attempts to leapfrog to the next floor. Like EN 13644, it also includes provisions for pre-cycling, or ‘cold’ movement before the test begins, covering thermal load, wind sway, seismic movement, and all these combined.

Alongside this perimeter firestop test, there is also now a relatively new standard that looks more specifically at assessing the spandrel assembly’s resistance to fire spread and the leapfrog risk. Unlike the aforementioned test standards, ASTM E2874 Standard Test Method for Determining the Fire Test Response Characteristics of a Building Spandrel-Panel Assembly Due to External Spread of Fire Using Intermediate-Scale, Multistory Test Apparatus has been designed to emulate a fire scenario at post-flashover stage inside a compartment. It analyses the ability of the spandrel assembly to prevent fire from spreading over the façade exterior to a room’s interior on the floor above the compartment of origin. The test specimen includes the exterior wall spandrel panel assembly, fasteners, structural supports, and any glazed openings. When applied in conjunction with ASTM E2307, this can provide a uniquely rounded view

Smoke Ventilation is an integral part of a buildings design for fire safety, without it you compromise the life safety of occupants.

of how both the perimeter firestop and spandrel insulation can achieve complete compartmentation, preventing fire from spreading floor to floor both internally through the curtain wall system and externally up its surface.

INDIAN STANDARDS

The Indian standard, IS 18190: 2023 - Fire Resistance of Perimeter Fire Barrier Joint System released in June 2023 by the Bureau of Indian Standards (BIS) references ASTM E2307, as well as UL 2079 – Tests for Fire Resistance of Building Joint Systems specifically for assessing air leakage of the fire test assembly, the resulting L-rating is an important factor when considering the ability of a passive fire protection measure to provide an effective smoke seal. Additionally, IS 18190: 2023 mandates adherence to the ISO 834-1 time-

temperature curve for evaluating the perimeter fire barrier joint system, which is the same time-temperature curve followed by EN 1363-1 and subsequently used within testing to EN 1364-4.

APPLYING BEST PRACTICE

Curtain wall systems present several unique challenges when it comes to ensuring passive fire safety. Choosing curtain wall perimeter firestops that have had their performance verified with testing that is reflective of their end use in the ‘asbuilt’ condition, such as the EN or ASTM standards, can not only enable compliance in many jurisdictions but also encourage best practice and, where possible, help to go beyond regulatory requirements to deliver enhanced spandrel protection, contributing to safer curtain walled buildings around the world.

Future of Cladding: Innovation and Trends in the Cladding Industry

Source: https://www.bdcnetwork.com/ Metal cladding

Building envelope means the protection layer around the building, which provides support to aesthetics, energy efficiency, and comfort to the people. Cladding is an important constituent of the building envelope, and in past years, it has undergone enormous changes. Cladding certainly is a future booster for performance, giving sustainability an edge more than required, bringing exciting new building technologies and materials to the fore. This paper tends to discuss some of the future trends and innovations that can shape the cladding industry.

SUSTAINABLE CLADDING SOLUTIONS

The very same construction industry also drives environmental consciousness; it includes the cladding materials. Traditional choices such as aluminium and concrete could have high embodied energy (the energy it takes to extract, process, and transport materials) and contribute to urban heat island effects. A 2021 RICS report approximates that nearly 40% of energyrelated CO2 emissions need sustainable

cladding solutions for the construction and building sector globally.

Here are some promising trends:

l Recycled and bio-based materials: Some of the systems of cladding, including metal panels and plastic composites, use recycled content in their products. This can reduce the environmental impact caused by the building to a great extent. Some biobased materials used are bamboo and wood composites in the product, which offer good thermal insulation.

The bio-based building materials market across the world is estimated to reach USD 48.2 billion by the year 2030 due to increasing demand for sustainability, according to Grand View Research.

l Green concrete: Precast concrete is one of the excellent building materials, no doubt, but its conventional production methods make it one of those contributions that assist in CO2 emissions. Formulations of green

concrete with recycled materials or supplementary cementitious materials, such as fly ash, make the panels more sustainable.

l Life cycle thinking: A future Life Cycle Assessment may also involve thinking about the life cycle of a cladding system, including embodied energy, operational energy, and requirements for maintenance, and thinking about what may be done with the product at the end of its life.

SMART CLADDING SYSTEMS

Smart building envelopes are equipped with the technology of cladding systems. The features of such systems include:

l Enhanced performance: It would include sensor-embedded cladding panels that can monitor the key performance metrics of the building, such as temperature, humidity, and air quality. It further adds that such data can be a key indicator toward the optimisation of building operations and guaranteeing occupant comfort, which can then lead to potential savings of between 10-30% of consumed energy.

l Self-Cleaning and self-healing materials: Self-cleaning cladding materials may feature in the cladding to bring down the maintenance cost or just to enhance the appearance of cladding in the long run. Other than the above, there are those materials that can have microcapsules of healing agents to repair small cracks or scratches and thus provide durability.

l Kinetic cladding: Cladding systems that are responsive to weather conditions or optimise solar energy collection. For example, louvred kinetic façades respond to sunlight both to shade from it in summer and gain as much solar heat in winter.

Cladding Trends

PREFABRICATED CLADDING SYSTEMS

Some benefits offered by prefabrication to the cladding systems revolutionised by prefabrication are:

l Faster construction: A faster construction time for the project and reduced on-site construction activity are easily obtained from off-site fabrication. This is, therefore, most befitting and a lot of help, more so to those urban setups or projects with a lot of pressure mounted on strict deadlines.

l Improved quality control: Improved workmanship standards come with factory-controlled prefabrication conditions that guarantee quality results; these are repeatable and reduce risks of error from that experienced in on-site construction.

l Reduced waste: Prefabrication leads to less material waste on-site, hence promoting reduced environmental degradation. The current global value of the prefabricated construction market is projected at 2.3 trillion dollars by 2025, increasing constantly.

FIRE SAFETY IN CLADDING

This has turned out very prime in the buildings, whereby the concern is that the cladding material should not be fireresistive at all, to ensure safety for the occupants.

Here are some key trends in fire safety:

l Stringent regulations: Another school of thought, after various high-profile building fires, especially the Grenfell Fire, led to new stringent regulations on the kind of cladding materials to use and how to install them in different countries. Most of the new regulations lay clear the fire resistance ratings and test standards for cladding materials.

l New and inventive cladding materials: As much as the shift in materials, so new cladding materials inch into offer probable fire protection. Foremost among those are fireperformance fibre cement boards and non-combustible metal composite panels having a fire-resistant core.

l Building Information Modeling (BIM): BIM allows fire safety requirements to be coordinated at the design stage. Conversely, with the proper incorporation of fire safety design considerations in cladding and installation details of a digital model, it is easy to spot potential fire hazards.

PERSONALISATION AND AESTHETICS

The cladding has the most powerful impact on the architectural appearance of the building, while more self-expression and design solutions will be visible.

l Biomimicry: Biomimicry finds in nature the inspiration for developing cladding materials with self-cleaning or selfhealing qualities inspired by natural events.

l 3D Printing: The most recent 3D printing technology is bound to revolutionise cladding design. This develops geometrical forms to such an advanced level, and therefore, architects will have a much greater level of freedom in developing custom cladding panels.

l Augmented Reality (AR) and Virtual Reality (VR): AR and VR technologies would be quite helpful for cladding design options in light of the building environment. This will enable the stakeholders to make properly informed decisions concerning aesthetics and functionality before actually taking up construction.

CHALLENGES AND OPPORTUNITIES

While the future growth looks bright, some of the challenges are there. New technologies and materials get integrated through continuous research and development. Besides, the longterm performance and durability of such innovative cladding systems are tested during their number of quality control tests.

Finally, the key aspect will be training the workforce and upskilling it to be in a position to work with new materials and prefabrication technology. This is because the trend would actually be most needed in the actual collaboration between architects and engineers on one side and material scientists and construction professionals on the other side.

The future of cladding is driven by sustainability, performance, and innovation. Together with those will be the façade embodied with sensors, which would be smart technologies, and prefabrication methods with sustainable materials at the forefront of the future building envelopes. Adoption of these trends by the cladding industry shall make very good contributions to making high-performance, sustainable, and aesthetically liked buildings. This will help have a much friendlier environment and technologically sound future.

CONCLUSION

The future of cladding is bright, driven by a focus on sustainability, performance enhancement, and innovative design solutions. Sustainable materials, smart technologies like sensor-embedded panels, and prefabrication methods will shape the future of building envelopes. As the industry embraces constant innovation, we can expect even more exciting advancements in cladding that contribute to energy-efficient, safe, and visually stunning buildings.

Smoke Ventilation Solutions for Public Buildings by SE Controls India

Airport PTBs and train stations play a pivotal role when it comes to nation building and mass movement of passengers safely and securely from one location to another. In recent times the government in India have fast tracked such projects as part of increasing India’s infrastructure capacity and owing to a rise in demand in travel, for both work and leisure.

Until 2014, only 74 airports were operational in the country. By March 2023, the Government operationalised another 74 Airports/Helicopters/Water Aerodromes, and the Government also aims to take the total to 220. During last 9 years since 2014, 11 more Greenfields Airports have been operationalized.

In 2023, over 327 million passengers passed through Indian airports, including close to 57 million international passengers. Many new Airports (both green and brown field) and large public infrastructure projects, including the much-awaited High-Speed Rail Network are being built across India in a large way to facilitate future growth demand. With this traffic set to grow, we will see heavy passenger movement owing large crowds moving in and out of such public spaces. Safety and Security are to be in prime focus here.

The system example shown below will allow for early detection and smoke

ventilation of such large public spaces, by which the panic situation and the suffocation caused by inhaling smoke can be greatly reduced. Smoke also traps heat, and causes toxic gases to enter our system, causing difficulty to breathe, see and generally perform during an emergency. Hence, it is crucial for such public buildings to have a robust smoke ventilation and clearance strategy.

The Best Practice – Below will briefly explain a mixed method of ventilation using Top Hung Make up air vents in the Curtain Wall glazing along with Bottom Hung Smoke vents or Roof Ventilation using hatches to remove the smoke in the incipient stages of the fire life cycle.

Applicable in – Airports, rail stations, closed in concert/events arenas, large scale public infra buildings

Our Goal for Ventilation – Large foot falls calls for the most efficient smoke ventilation and control strategy making sure to have the most effective evacuation planned for the occupants in case of a fire emergency, with the least smoke stagnation possible.

In spaces with tall stacks it is beneficial to design the smoke ventilation strategy using a two pronged approach, giving us a price optimum, yet effective solution to ventilation of such spaces.

Stack effect works like your typical chimney, hot air rises the stack and travels quicker when ventilated from the lower section for fresh air, creating a pressure differential causing escape of hot gases and smoke.

The use of make-up air vents in the glass facade allows to bring in the fresh air required as per calculations made using CFD modleling. Actuators and Compatable controls tested and certified to EN only are to be used.

Best Global Practice - Vents are to be tested to EN12101-02 along with all necessary hardware and automation kit intact there by becoming a harmonised and #TestedSolution.

Smoke Hatches on the roof will allow the the escape of hot gasses and smoke. Care is to be taken to the sizing, quantities and placement of the vents and area of smoke exhaust, also known as, the Geometric and/or Aerodynamic Free areas, whihcever is applicable/asked for.

The vent was manufactured by Ventline, Dubai (our partners for Smoke Hatches, Louvers, with Actuators and Controls by us tested to EN standards)

The vent is to be furnished with such details, along with system tested to EN12101-02, including the motors which are to be used, providing a harmonised and #TestedSolution.

In Airports such as the new Mopa, Goa Airport make use of this ventilation stragery, thereby making it safer for the public visiting and transiting such airports by us. Maintenance is key to such systems functioning when required, and only the authorized OEMs must be given the contract to maintain such systems from the get go.

Cutting-Edge Cladding Solutions

Smart & Environmentally Responsible Choices

Cladding of buildings is one of the most expressive, inspiring and complex aspects of building design. The basic function of an envelope or enclosure of a building or structure is to protect the covered or otherwise conditioned interior spaces from the surrounding environment. Cladding is the application of one material over another to provide skin or layer intended to control the infiltration of weather elements, or for aesthetic purposes.

The façade is required to fulfil a wide range of technical and architectural roles, including weather tightness and structural. The cladding has to protect a building from moisture and wind and is an integral part of

a wall assembly, responsible in surprising ways for a building’s overall thermal performance. A wholesome building should provide an acceptable level of thermal comfort with minimal environmental impact.

The façade and cladding industry has gone through a sea change in the past decade. The market is flooded with materials of different textures and colours. WFM Media spoke to many experts in the construction sector including architects, façade consultants, manufacturers of cladding materials and civil engineers on the advancement in the cladding sector and the newest in cladding technology and materials. Here is what experts have to say about the latest in the industry.

EXTERIOR CLADDING MATERIALSIMPACT ON BUILDING’S COMFORT AND SUSTAINABILITY

Cladding materials play a critical role in creating a comfortable and sustainable building. According to Ar. Vikrant Sharma, Founding Partner and Principal Architect, Hivemind Design LLP, exterior cladding materials

reduce heat gain and provide insulation, regulating interior temperature and minimising energy consumption. Additionally, these materials ensure a comfortable temperature inside by controlling heat transfer and reducing the energy footprint of the building.

Cladding acts like a building’s thermal envelope, says Ar. Gagandeep Kapila, Co-Founder & Principal Architect, WMA. “We prioritise materials with high thermal resistance, like insulated concrete panels or rainscreen systems. These create a barrier, reducing heat transfer in summer and heat loss in winter. This translates to a comfortable interior environment while minimising energy use for heating, ventilation, and air conditioning (HVAC)

systems. We also explore materials like terracotta or fibre cement that offer natural ventilation through their breathability, further reducing reliance on mechanical cooling”, adds Ar. Kapila.

Bakul Chandra Co-founder, Mentor & Design Strategist, Renascent Consultants adds that exterior cladding materials play a crucial role in determining interior comfort and sustainability by providing insulation, weather protection, solar heat control, durability, moisture management, and aesthetic enhancement. The choice of environment-friendly and energyefficient cladding options can significantly improve the overall performance and sustainability of any building.

INNOVATIVE AND HIGH-DEMAND CLADDING MATERIALS

The world of cladding is constantly evolving and we’re excited about some innovative materials. Prefabricated lightweight aggregate concrete (PLAAC) panels are gaining traction, reveals Ar. Kapila. These offer superior insulation due to air gaps within the panels and allow for rapid construction due to prefabrication. Biocomposite cladding, made from recycled materials like wood fibres and natural resins, is another favourite. It boasts excellent sustainability credentials and a unique aesthetic, making it a win-win for design and the environment, adds Ar. Kapila.

Innovative materials are used to reshape exterior cladding in architecture while meeting sustainability objectives. According to Ar.

Natural wood or green walls are also being used to promote well-being.

Offices aim for a modern appearance and functionality. Glass curtain walls are common in offices for maximising natural light and creating visual impact. Glass façades maximise natural light, while metal composite panels and high-pressure laminate cladding offer sleek aesthetics and easy maintenance. Office spaces emphasise flexibility and sustainability, incorporating adaptable cladding systems and green building materials.

FIRE SAFETY STANDARDS OF CLADDING MATERIALS

Fire safety standards for cladding materials involve compliance with building codes and regulations, ensuring materials meet flame spread and smoke toxicity requirements. Concerns regarding safety and security include resistance to weathering, impact resistance, and resistance to vandalism or intrusions, explains Aggarwal. Additionally, proper

COLOURS, DESIGNS

Materials: Sustainable and innovative materials are gaining popularity, including engineered wood products like cross-laminated timber (CLT), fibre-reinforced polymers (FRP) and bio-based materials such as bamboo or reclaimed wood. Metal cladding, particularly aluminium and zinc, remains popular for its durability and modern appeal. Additionally, translucent materials like polycarbonate sheets are increasingly used for their ability to transmit natural light.

Colours: Neutral and earthy tones continue to dominate, reflecting a preference for timeless and natural aesthetics. However, there is also a growing interest in bold and vibrant colours, as well as metallic finishes, adding visual interest and personality to building façades.

Designs: Contemporary designs often feature clean lines and minimalist aesthetics, with an emphasis on simplicity and functionality. However, there is also a revival of interest in textured surfaces, geometric patterns, and intricate detailing, adding depth and visual intrigue to cladding systems. Modular and prefabricated cladding solutions are gaining traction for their efficiency and ease of installation, allowing for greater design flexibility and customisation.

(Ar. Gaurav Sanghavi, Co-founder, Pentaspace Design Studio)

installation and maintenance practices are essential to mitigate risks associated with cladding, such as water infiltration or structural instability.

Fire safety standards for cladding materials are vital to prevent fire spread, focusing on fire resistance, combustibility, and smoke production, adds Ar. Sanghavi. Materials must meet specific fire classification ratings. This includes assessing their resistance to fire, how easily they burn, and the smoke they produce. We also need to make sure they don’t catch fire easily, and that any smoke they produce isn’t harmful. It’s important to choose materials that can withstand weather to stop water from getting in, maintain a building’s structure, and protect people from falling debris during emergencies. Taking care of

these things keeps buildings safe and protects the people inside.

Fire safety will depend on the base on which the cladding material is installed, says Ar. Gandhi. If the base material is non-combustible like a concrete or a brick wall, then the fire standards of the external cladding material will matter less. From a longevity perspective, the adhesion of the cladding material with the base envelope becomes critical, as well as the life and LCA of the materials.

WHAT LIES AHEAD

Future cladding materials and designs should emphasise sustainability, resilience, and innovation. Materials which are easy and quick to install, modular to adapt to the existing envelope in case of retrofits, and ones which are 100% recycled would be game changers for the real estate industry.

Bio-based materials, such as engineered timber and biopolymer composites, offer environmentally friendly alternatives to traditional cladding materials. Advanced technologies, like self-healing coatings and integrated photovoltaics, could enhance functionality and energy efficiency.

Cover Story

Design-wise, dynamic façades capable of adapting to environmental conditions and user preferences may become prevalent, blurring the boundaries between architecture and technology.

AI advancements will likely revolutionise the cladding industry, leading to smarter, more energyefficient choices in the next 25 years.

Products based on nanotechnology will indeed play a significant role, offering self-maintaining properties and the ability to adapt over time by changing colour, texture, and more, creating dynamic architectural expression. Translucent solar cladding also appears to be a promising future trend, harnessing renewable energy while allowing natural light to penetrate indoor spaces, blending functionality with aesthetic appeal.

Furthermore, with a more sensitive approach to sustainability, carboncapturing buildings will likely become more prevalent, actively reducing carbon emissions and mitigating climate change. This could include the widespread use of innovative materials

like carbon-negative concrete, selfhealing bioplastics, or nanomaterials with enhanced thermal properties.

Also, buildings might have smart cladding with sensors that monitor things and adjust as needed. We might also see more nature-inspired designs like living walls or green façades, which make people feel good and help the environment.

Plus, using prefab cladding material could make building faster and let architects be more creative. The designs should strive to harmonise with their surroundings, contribute to energy efficiency, and enhance the overall quality of built environments.

Overall, the future of cladding holds exciting possibilities, where innovative technologies and sustainable practices converge to create buildings that are not only beautiful and functional but also environmentally conscious and responsive to their surroundings. The future cladding solutions aim to balance aesthetics, performance, and sustainability in response to evolving architectural and societal needs.

Evolve Each Typology of Building”

Face to Face

Could you tell us about your educational background and your experiences as an architect at FHD?

I graduated with my B.Arch. with University Gold medal and Best Outstanding Student award from NIT Trichy. Later pursued my M. Arch. with full University Fellowship from The Ohio State University, USA. I had the fortune to study under the tutelage of Theorist Jeffry Kipnis, Jose Oubrerie (associate of Le Corbusier), and Peter Eisenman as a visiting professor. I have worked in India and the US in leading practices, and have been a part of FHD India since 2017, leading a team at our Hyderabad office earlier. We worked on diverse projects across India and international projects. Since Nov 2023, I have been leading our Bengaluru office.

What inspired you to pursue a career in architecture and design?

I was passionate about sketching and painting right from my school days, apart from a strong academic background in maths and science. Joining B.Arch was my way of bringing all my strengths together. Since then NIT Trichy and Ohio State University (OSU) shaped me into who I am now. Today, I love the deep intricate relationship between architecture theory, built environment, and human behaviour.

What type of projects do you specialise in? Brief some of your milestone projects with FHD? At FHD, we work on all major typologies of built programs, across India and around the world. We work to challenge and evolve each typology of building.

My first project in FHD is Polycab Experience Centre, Gujarat which has won several recognitions post recent completion for its Sustainable design and reimagined workspace. I worked on several international projects across commercial, retail, hospitality, and masterplan typologies in Dubai, Abudhabi, Cairo, Saudi, and Seattle, where we tested the architectural theory and form development to the limit.

In Commercial typology- our work includes Polycab Experience Centre – Vadodara, and ongoing development for Syna in Madhya Pradesh. In Housing, we worked on Organo Antharam in Hyderabad, Srias Boat Club in Hyderabad, Capstone Mid Summer Rain in Bengaluru, and a housing development for Adani Realty in Panvel near Mumbai, to name a few. In master planning, our works include a masterplan for Adani in Vishakapatnam, IRA Aerocity Hyderabad and TVS Estates Tamil Nadu.

In Institutions and public buildings, our works include – Ignite International

Raipur and the International School of Hyderabad. Our vertical housing includes 2getherments in Bengaluru. Our private residences include those in Vadodara and Seattle. These are just some of the projects of FHD where I have led the design team over the last 6 years. FHD has a much larger portfolio.

In each of the above projects, we challenge the conventions of typology and work to push the boundary of design in a way specific to the project needs. That is what sets us apart. We work closely with all the stakeholders of the project to transform the design thinking into a unified integrated project.

What is your take on sustainable practice in architecture today?

The concept of sustainability has come a long way over the last decade. Social awareness, climate change, and the national push toward renewable energy have made sustainability an integral part of design today. FHD has been an early adopter and sometimes a pioneer in sustainability strategies. Organo Nandi was one of the early projects to imagine Sustainability at a community level. It is a self-reliant community with farms, and strategies towards water, air, waste, food, and energy. It uses only 10% of the land for construction (compared with the market

Ignite International in Raipur: In our toddler and primary school

standard of 55%) leaving the rest open to nature. Today we are incorporating principles of sustainability across all our projects in some form or the other. Our Polycab EC project produces its energy from over 190KW of solar power installed on the roof. The benchmark we set is getting higher with each project, which we are proud of.

How would you define your design and installation process for façades and fenestrations in your projects?

We believe the façade is an integral part of the design and not a surface finish. The concept & design of building strategies the program, user requirements, identity, and performance of a building. The façade, being an element of the building is critical in achieving the above said goals beyond aesthetics. We perceive buildings as 3-dimensional entities and not extrusions of plans. So we work on the façade strategy right from the initial concept stage. As the design evolves, the façade evolves with it. We try to bring in façade-related vendors and consultants in the design development stage to share their inputs and for us to understand the materials at a deeper level. Fenestrations are a critical part of design expression, programmatic functionality, and energy performance. In design development, we use software modelling and physical modelling to test the façade. Sometimes we need prototyping as well.

During the tender and procurement stage, we focus on specificifications, fine details of the façade, and fenestrations. Finally, during execution, mock-ups play a critical role in the façade. We test all our unique designs with mockups on-site and finetune them aesthetically and performatively based on on-site conditions. Finally, the full façade is executed. This allows us to create an integrated façade design.

Could you please brief me on the latest trends in façade and fenestration designs, materials, and technologies? I see the following new materials making a difference in façade design.

Engineered Stone: Today there are

Face to Face

several alternatives to real stone, that are more sustainable than mining stones. Terracotta-based stone finish, Cementbased stone finish, artificial base with a thin stone surface, ACP with stone finish, and engineered marble are good alternatives for stone, especially for façades since some of them can bend to clad curved walls. They are much lighter in weight, affordable, and can maintain texture consistency across scales.

Fabric: Fabric opens up a new dimension in façade design. Traditionally used for roofs, newer fabric products are available for façade application. Fabric is light, tensile, and easy to use. They can be used as shading devices, to enhance privacy without hindering views, for aesthetic firms. They are also waterproof and fire retardant (specific products). This makes the fabric a versatile material.

IN TERMS OF TRENDS:

Make in India: A decade back, many advanced façade materials were imported. Today many of those same companies manufacture locally, which is a game changer, especially in the construction Industry. The product range has expanded significantly to respond to local climatic and cultural needs. This also produces unique aesthetic looks. The product cost comes down without compromising quality. The connected ecosystem developsthereby improving the maintenance and serviceability of the material. I believe this trend will continue until every brand starts local manufacturing at least partially. At

FHD, we strongly support products that are made in India.

Please throw some light on the façade and fenestration designs of a few of your favourite projects. I will look at a few of our projects

Polycab EC: We created a curtain glass system towards the views on the East and South. The balcony overhang shades the south while vertical aluminium fins shade the east. We used software modelling to study the lux levels of light and optimised our fin design to maximise daylight. Postconstruction, we measured light levels across work areas to confirm that we get sufficient daylight for work throughout the year. The arrangement of the vertical fins creates the unique character and identity of the building.

Dhriti Nirvana: The site in Zaheerabad has Laterite rock which is a natural

construction material. So, we used laterite blocks, as the building material. It is low-cost on-site and has good thermal properties in hot and dry weather. It also has an excellent aesthetic character when exposed. Its major limitation is porosity towards the water. So we exposed the material in shaded areas while plastering it in rain-exposed areas. This combination creates a unique aesthetic language for the project.

Srias Boat Club: The project with group villas is facing Medchal Lake creating beautiful vistas and a natural breeze. But shading is critical for the Hyderabad heat. We wanted to create a contemporary high-tech façade in continuity with the design language. So we designed a custom module of a jalli, such that it can be placed in 8 different placements. We used parametric software to test various combinations to arrange the jalli in the façade. We 3d printed 8 numbers

of jallis in a 1:1 scale to physically test the jalli arrangements. The final jalli shall be manufactured in Aluminium, with MS reinforcements to hold them in place. Aluminium avoids rusting in the humidity, while the MS provides strength against the wind. Overall, each villa can have a unique look, due to the variation of the jalli placement, while the use of a single module ensures the efficiency of procurement.

Private Residence in Vadodara: The farm-facing villa needs shading from the Gujarat heat while maximising views. The concept needs a contemporary strategy while using earthy materials that connect to the farm villa experience. The conventional terracotta tiles are too vernacular. So we selected a refractory clay jalli (similar to fired bricks). They have a higher strength, sleeker look than regular jalli, and larger frame size - thus larger cutouts for views The limitation is their

higher weight. We designed large jalli frames that can be reinforced with MS on the rear side, which would not be visible fully from the front. The natural exposed look of the jalli ages well with time.

Ignite International in Raipur: In our toddler and primary school, the children in classrooms are of varying age groups. We need views that can be enjoyed by all. Daylight and ventilation are critical for a healthy learning environment. Meanwhile, we also need shading from the central Indian heat and direct sun. First, we created a deep façade with a double wall that provides horizontal and vertical shading for all windows to cut direct sun. It also doubles up as a shelf area indoors. Then we created a high daylight fenestration, which allows deep daylight penetration. The operable windows are placed in unique sizes at different heights. This opens view and ventilation for different ages.

The combination of multi-age windows, daylight windows, and a deep façade creates a unique and playful aesthetic from the exterior symbolising a playful school for kids.

Please brief on future façade technologies, designs, and materials that you wish to see in the next 20 years.

The future of façade design looks bright with a plethora of upcoming materials and technologies.

Adaptive and Responsive façade systems: My 2017 thesis at OSU included a technology demonstrator of a façade system that can adapt to changes in temperature and humidity through a preprogrammed electronic chip. Selected buildings around the world have already installed such systems in scale. I see that becoming commonplace in the

future. Especially with the sudden rise of Artificial Intelligence in life applications, it can manage adaptive façade systems effectively in the future.

Bio-degradable and Low Carbon footprint materials: Today we are moving away from carcinogenic materials from the past. It is not long before we move away from non-biodegradable materials. New technologies are already available and demonstration buildings use them. It will become the norm in the future.

Digital façades: Sci-fi films since the 70s have predicted the future with display façades. I believe the future shall have digital façades more commonly, but not as mere advertising boards, but more as a character-creating device. The Dome in Dubai Expo 20, and in LA are already demonstrating the power of digital façades. But they are still façades made for the sake of display. More real building façades will become digital.

What is your advice to young and upcoming architects?

There are a couple of points that helped me in my early years that I believe will help other young architects as well:

Young architects today are motivated by colourful Images of buildings on social media. It is important to visit some of the great and classic buildings in person to understand better the 3- façade dimensionality of architecture – the form, space, scale, as well as the performative and experiential nature of architecture. How a building responds to its context is equally important which photos do not fully communicate.

We work on advanced cutting-edge technologies. But It is important to build hard skills and basics at a young age to be successful in any profession, more so in architecture. Hand sketching, physical modelling, basics of structural design, hands-on feel for construction materials, site visits, case study visits, and reading architect’s writing, go a long way in building a long career. Software is great to learn, but it evolves with time. The core skills are timeless.

Translating the Performative Design Of The Façade into an Aesthetic One Polycab Experience Centre

Polycab Experience Centre is located in Halol – the industrial hub of Gujarat, close to Vadodara. The project aims to bring 3 primary programs– a corporate office, Experience centre, and auditorium under one sustainable roof for the client who is one of India’s largest cable manufacturers. The geometry of the building intends to protect the existing trees on site. The auditorium floats

above an atrium, connecting the office zone and experience centre, while the atrium connects to the factory behind. The double block configuration selfshades the central landscape court, while the conference room as a bridge connects the two blocks across the court. The basement G+ 3-storey office block houses the employees and amenities. The experience centre houses a museum of the company’s exhibits

and conference facilities. The auditorium is accessible from both spaces.

The drop-off is at the shaded atrium, where the user can enter either the office or the experience centre. The atrium expresses curvilinear intersecting beams at the ceiling. The office has a triple height naturally lit entry lobby. The mural depicts the ‘Banyan tree’, characteristic of the local culture, and copper that carries

energy inside a cable to create light. The mural is complemented by suspended glass leaves forming the chandelier on the roof. Each office floor overlooks the central atrium. The cafeteria on the top floor is naturally lit while overlooking the natural views. It has an accessible activity terrace above the conference bridge, overlooking the landscape. The landscape uses repurposed – cable packing trays that are locally available.

The project is designed to become a netzero energy building. Façade design is a critical part of achieving the net-zero energy goal. Glazing is maximised on the east and south façades based on the vistas of the site. The west façade has minimal fenestrations as it is facing a factory. The glass used is specified as Low-E double glass to minimise

thermal conductance. The south façade needs horizontal shading. The balcony overhangs horizontally shade the southern façade. The eastern façade needs vertical shading. This is provided by aluminium fins that are strategically designed to maximise views to hills on the east but cut a direct sun angle. This ensures optimum lux levels required for office spaces. The combined setup reduces the energy requirement of the building by 20% from the base case of unshaded regular glass. Lux levels at each work area were simulated using software to maintain the 300 lux necessary for office work for most times of the year. The light levels were tested post-construction to ensure daylight is sufficient for work close to 10 months in a year.

The solar panel system on the roof designed for 195KW capacity offsets 40% of all energy needs of the building. The additional solar panels laid on a neighbouring factory of the same project, aspire to offset the other 60% of the energy needs, thereby making it a true net-zero building. 70% of all construction materials involved were procured within a 100km radius to limit embodied energy. Efficient water fixtures and rainwater wells reduce the water need of the building by 30%.

There are several outdoor spaces, that can be used at different times of the day. The drop-off atrium is a spillover from

SentryGlas® that is known as SentryGlas® Xtra™ that can be processed by our customers just like they process PVB. Processing of regular SentryGlas® is a bit different. We are promoting Trosifol® Spallshield® CPET which is a new product for the Bullet Resistant Glazing (BRG) applications in India. Its unmatched durability and ability to perform at elevated temperatures make it outperform conventional BRGs that make use of Polyurethane and Polycarbonate. We have also launched BirdSecure® Pro to prevent bird death due to their accidental collision with transparent or highly reflective glass façades. Trosifol® Extra Stiff Pro is the latest addition to our product portfolio of structural interlayers. It is the stiffest PVB interlayer with exceptional edge stability and post-breakage strength that outperforms the competition. For the automotive industry, we have Trosifol® The Wedge for HUD (heads-up display) and special sound protection films.

What are the latest advancements in your R&D, technologies in production, and products?

Tell us about some of the iconic projects in which your products are used as exterior cladding materials.

SentryGlas® is our hero product that has been used in several mega projects all over the world due to its uniqueness. Shanghai Tower in China, World One by Lodha in Mumbai, Omkar 1973, Kalpataru Vista, Apple store projects all over the world, Steve Jobs Theatre at Apple Head Office at Cupertino.

Please throw some light on the latest materials, technologies, and trends in façade cladding in India.

There can be so many perspectives to answer this question. From the perspective of an interlayer manufacturing company,

we see sustainability as a new mega trend in the making. The trend is catching up slowly in India as we are mostly followers of the trends. Developed countries like Singapore have chalked out plans to impose a carbon tax and it will be no wonder if India follows it in future as we can foresee regulations on reducing carbon emissions will become stringent. Saint Gobain launched its lowcarbon glass in 2023 in India. The use of lowcarbon interlayers with low-carbon glass will further add value from a sustainability perspective. Recyclability of a product is one of the key steps towards sustainability. However, at present, laminated glass cannot be recycled as the separation of interlayer from glass fragments is a tedious process, whose commercial viability and scalability are yet to be fully established. Kuraray has taken active initiatives in this direction to solve this issue and contribute its bit to save our planet.

Tell us about the testing and certification methods for your products, especially those for fire safety

All our Trosifol® PVB and SentryGlas® ionoplast interlayers are commercialised after mandatory testing required by the applicable EN, ISO, ANSI and ASTM standards and of course Indian Standards. In fact, our products exceed the minimum performance required by Indian Standards. Talking about fire safety, it is noted that

laminated glass is not fire retardant. However, SentryGlas® shows better performance than PVB in terms of flame spread and flammability, indicated by tests done on interlayers as per ASTM E84.

What do you see as the main challenges faced by the industry?

There are multi-fold challenges related to the use of laminated glass in the industry. Unfortunately, the awareness about the usage of laminated glass in buildings in tier 2 and 3 cities of our country is not what it should be as per the standards framed by the Bureau of Indian Standards. We also see a reluctance for the use of laminated glass due to associated risks of delamination that often result from failure to comply with best practices of glass tempering lamination and installation. Kuraray takes a lot of initiatives to raise the bar for the quality of laminated glass in the country through its QNL (Quality Network of Laminators) program. Next comes, the issue arising from the use of counterfeit products as we have noticed the import of fake products from China. Unfortunately, it is not so easy to identify the make of the interlayer once the glass has been laminated.

What keeps your company ahead of its competitors in terms of products and services offered?

We have some unique products like

SentryGlas®, Trosifol® Spallshield® CPET, Trosifol® Diamond White and Trosifol® Brilliant Black, Trosifol® SC Monolayer (for acoustic applications) that have no match in the industry. We work very closely with our customers to ensure they get our best service. Our customers who are certified for our QNL program have an advantage over others for winning projects with demanding specifications.

Where do you see the glazing industry evolving over the next 10 years?

Market research reports indicate the growth of the glazing industry is proportional to the growth in the real estate Industry. The way India’s real estate market has grown in the past from public housing projects to, the post-liberalisation, next-generation journey from medium to large-scale

projects including IT, Shopping Malls, Expo centres, Airports, Commercial Office Buildings, Big Budget Housings resulting in 2024. India’s Real estate market is the fastest-growing market in the world.

As per a market research report of Technavio, the trends are clear as in 2022 homes worth INR 3.2 Lakh Crore were sold, the next year it has grown to INR 4.5 Lakh Crore and that’s a 38% rise in just 1 year. Growth has been stable, the fundamentals are strong and the Central bank has also not increased the interest rates resulting in a clear indicator of the Indian Economic Growth trajectory. Also, with increasing technological advances in the façade industry, future buildings are

Tensile Architecture

PSG College of Architecture, Coimbatore

As we mark our 50th anniversary, we take pride in celebrating the milestones that have shaped our journey. To commemorate this, we have chosen to shed light on previous projects in which we actively participated. Today, we shine a spotlight on one of those successful projects: The PSG College of Architecture, Coimbatore.

The Building’s structure is wrapped in a 3D Diamond-shaped textile envelope made from Précontraint 381 in Silver Grey. Installation was completed by local contractor Duvo Engineering, which specialises in tensile architecture with expertise spanning design, engineering, manufacturing, assembly, and maintenance.

However, installation proved one of the biggest challenges in this project, as each panel had to be lifted individually into position while dealing with strong winds typical of the area. The play of curves

and different-sized panels, combined with the fabric’s glossy finish, make for a distinctive design that changes with the light throughout the day. The 3000 sq m of fabric that now wraps the building creates a particularly stunning show of light and shadow.

Despite the concept’s appeal, the development of the textile facade raised a number of concerns, including with regard to securing approval for the solution in terms of ventilation, fire safety

and especially statics. At the onset of the development process, the architects were told by many prospective contractors and professional organisations that it would simply be impossible to deliver this project. But convinced by the architect’s passion for the sophisticated design concept, the clients emboldened everyone involved in the project to keep looking for possible solutions.

The key to this successful concept lay in two factors: the ability to take full

advantage of tension forces and to find a novel approach to tensioning on the one hand, and a choice of membrane with a well-established stretching behaviour on the other. In this case, a fibreglass textile could not be used because of the

forces involved. Conversely, Serge Ferrari’s high-resistance PVC-coated polyester membrane offered obvious advantages, not only in that it was easier to work with and shape, but also because of its stretchability, which ensured better control of the considerable tension forces it would have to sustain.

The broad palette of 17 colours currently available for Frontside View 381 was another decisive element. In their design, the architects had envisioned a silver or light grey shade, which allowed for a wide range of possible colour options. Their choice eventually settled on Frontside View 381 — 3121 Shifting Grey, which ideally complemented the concept and created a beautiful sculptural effect in combination with the undulating shape.

The Overlooked Essential: The Importance of Investing in Quality Windows

Viewing the domain of residential building and renovation, immediate comforts often overshadow long-term investments. While luxurious bathroom fixtures and trendy decor capture attention, a vital component often goes unnoticed: the window.

Windows serve as more than mere openings; they offer access to natural light, fresh air, views, and safety. Despite this, many homeowners overlook the significance of quality windows, opting for temporary fixes or budget-friendly options.

Though windows may initially seem inexpensive, their composition determines their true value. Investing more in quality windows ensures enhanced safety and features, proving cost-effective in the long run. Choosing security glass over regular glass may raise initial costs, yet it provides superior

protection against break-ins and accidents, offering peace of mind and long-term security.

Neglecting quality windows can have significant repercussions in terms of comfort and finances. Here’s why prioritising good window installation matters during home construction or renovation:

• Energy Efficiency: Properly installed quality windows significantly impact a home’s energy efficiency, regulating

indoor temperatures and reducing the need for excessive heating or cooling, leading to long-term utility bill savings.

• Durability and Longevity: Well-made windows are built to last, minimising the need for frequent repairs or replacements.

• Health and Comfort: Quality windows facilitate proper ventilation, creating a healthier and more comfortable living environment by maintaining indoor air quality.

• Aesthetic Appeal: Beyond functionality, well-designed windows enhance a home’s architectural style, adding character and visual interest.

• Safety and Security: Quality windows with sturdy frames and locks provide a barrier against intruders, ensuring the safety of occupants. They also serve as emergency exits during crises.

While it’s tempting to focus on immediate comforts and trendy decor, investing in quality windows is crucial. By prioritising energy efficiency, durability, health, aesthetics, and safety, property owners can create a more comfortable, sustainable, and secure living space.

Choosing Alfen Windows means prioritising customisation, quality, and long-term value. With Alfen, you’re investing in peace of mind and a more comfortable living environment, supported by exceptional after-sales service.
