Understanding the structural behavior of the façade is essential for façade designers and engineers to ensure the sturdiness and resiliency of the entire building enclosures.
Ensuring the structural performance of a building façade is vital in design and construction. Façade designers must analyse loads like wind, snow, and seismic forces, selecting materials that balance aesthetics with structural strength. Attention to connection design accommodates movements such as thermal expansion while integrating expansion joints controls stress build-up. Testing and simulations refine façade behavior under various conditions, and code compliance ensures safety standards. Collaborative efforts between architects, structural engineers, and façade engineers seamlessly integrate aesthetic and
structural considerations. Long-term maintenance and quality control during construction and effective documentation and communication contribute to creating a resilient and aesthetically pleasing building envelope.
The façade shall be designed to transfer various loads, including dead loads (self-weight), live loads (occupant loads, wind loads, snow loads), and thermal loads, to the building’s structural system. The façade support includes columns, beams, brackets, and anchors, which provide the necessary structural support and ensure load transfer to the main structure.
The design of a building façade involves critical considerations for load transfer and support, ensuring the structure’s safety and stability. Dead loads, representing the weight of façade components, necessitate an efficient structural system for proper distributionLive loads, including occupant, wind, and snow loads, demand façade support elements capable of safely transferring these dynamic forces. Thermal loads arising from temperature variations require mechanisms like expansion joints to accommodate material movements. Façade support elements like columns, beams, brackets, and anchors play a vital role, requiring careful consideration of material properties and load distribution. The load transfer path must be
designed to avoid localised stresses, and material selection should prioritise strength and durability. Compliance with building codes is essential, contributing to a welldesigned façade that enhances aesthetics while ensuring safe load transfer for overall structural stability and longevity.
The façades contribute to the overall stability of the building by resisting lateral forces such as wind and seismic loads. In conjunction with the building structure, the façade system forms a stable and interconnected system that can resist external forces and maintain structural integrity.
The exterior building envelope façades are pivotal for a building’s structural stability, safeguarding against wind and seismic forces. Building envelopes are carefully designed, detailed, and engineered in tall structures to endure significant
wind pressures. The façade system, encompassing cladding and glazing, effectively distributes wind loads to the building structure. Façades absorb and dissipate seismic forces in earthquake-prone areas, working harmoniously with structural elements. The building envelope is crucial in even load distribution across the structure, ensuring balance during adverse conditions. Their seamless integration with the building structure enhances stability, preventing potential failures. Material strength and durability are
imperative, contributing to the longterm resilience of buildings.
The façades are designed to withstand wind pressures and transmit these loads to the building structure. The façade’s shape, orientation, surface area, and choice of materials influence wind load distribution and resistance. Façade engineers employ techniques such as wind tunnel testing, computational fluid dynamics (CFD), and structural analysis to determine
the wind load effects and design appropriate façade systems.
Designing wind-resistant façades is crucial in engineering, especially in windy areas. Influencing factors include building shape, orientation, surface area, and material choice. Irregular shapes and prevailing winds impact wind pressures, while larger surface areas expose buildings to higher forces. Heavy materials offer better resistance, sometimes. Adherence to wind load codes and standards is vital. Design considerations involve incorporating wind-resistant features, pressure equalisation systems, and regular maintenance. A holistic approach ensures effective façade design, crucial for tall or complex structures facing significant wind forces.
Façade materials, especially metals and glass, undergo thermal expansion and contraction due to temperature variations. Façade engineering considers the coefficients of thermal expansion of materials and incorporates appropriate expansion joints and detailing to accommodate these movements and prevent structural damage.
Façade engineering is crucial for buildings, especially metals and glass, as they undergo thermal expansion and contraction due to temperature variations. Materials expand when heated and contract when cooled, with varying coefficients of thermal expansion (CTE). Metals like aluminium and steel have higher CTE, necessitating careful engineering.

The choice of façade materials, such as concrete, stone, granite, steel, aluminium, glass, or composite panels, significantly affects the structural behavior of façades. Façade engineers carefully select materials based on their strength, durability, weight, and compatibility with the building structure. The connections between façade elements and the main structure, including anchors, fasteners, and support systems, must be designed to ensure proper load transfer and structural stability.
For example, the aluminium alloy 6061 is a heat-treatable alloy that offers excellent mechanical
properties, including high tensile strength. It has a typical tensile strength range of 276-310 MPa (40,000-45,000 psi), depending on the temper (condition) of the material. This alloy is often used in structural applications, such as building frames, aerospace components, and automotive parts, where strength is critical.
On the other hand, aluminium alloy 6005 is a non-heat-treatable alloy with good formability and weldability. It typically has a slightly lower tensile strength compared to 6061. The typical tensile strength range for alloy 6005 is around 207276 MPa (30,000-40,000 psi). This alloy is commonly used in architectural applications, such as window frames, curtain walls, and extruded profiles.
The selection of façade materials and the design of connections are vital for a building’s performance and safety. Façade connections, including anchors, fasteners, and
support systems, must be designed, engineered, and detailed to ensure proper load transfer, accommodate movement, and resist corrosion. A well-coordinated approach involving collaboration between architects, structural engineers, and façade specialists is essential. The summary underscores the importance of balancing structural integrity, aesthetics, and functionality for an optimal façade solution that meets technical and design requirements.
Façade engineering involves close collaboration with structural engineers to integrate the façade system seamlessly with the building structure.

In today’s times, with the energy crisis, rising costs, and the impact of global warming having a major impact on everyone’s lives, things that were once taken for granted are now being redefined. So too in the construction world, where new initiatives and materials are gaining ground...and rightly so!
The use of fabric façades, little known until recently, is becoming an increasingly popular option for new construction and renovation projects because of the energy and cost savings they offer.
Fabric façades can provide significant energy savings, making them an attractive option for building owners looking to reduce their energy costs. They also offer a variety of creative options, making
them an attractive option for many building projects.
Textile façades help reduce energy costs by providing insulation from
the elements. The fabric of the façade acts as a kind of “blanket” for the building, trapping heat in the winter, keeping warm summer air out, and generally reducing the amount of energy needed to heat
and cool the building. This can significantly reduce energy costs for building owners.
In addition, and depending on the type of fabric, it can also act as a sort of “air filter” for the building, keeping dirt, dust, and other potentially harmful particles out of the air. This helps reduce the amount of air pollution in the building, making it a healthier environment for occupants.
A wide variety of creative options can also be achieved with fabric as a façade cladding material. The fabric can be printed in any design the building owner desires, adding an attractive aesthetic to the building’s exterior.
Unique three-dimensional forms can also be easily created using textiles, giving old or new building projects a beautiful one-of-a-kind look.
Since fabrics are lightweight and easy to install, the installation process can be completed quickly and inexpensively. This can lead to significant savings over traditional masonry, steel, or wood-based façades. In addition, the fabric is highly durable and resistant to harsh weather conditions, meaning it will maintain its attractive appearance for years to come.
Because long spans can be covered, substantial savings can be made on the understructure. This easily results
in a cost saving of 50% compared to other types of cladding.
Thanks to a very low ecological footprint, fabric façades are an ideal application to make the building and renovation industry more sustainable. The creative potential - also thanks to the possibility of durable printing - is endless, while the costs are relatively low. A building fitted with façade mesh is characterized by optimum thermal and visual comfort.

With 16 years of hands-on experience in façade design, engineering, testing, and inspection, this article aims to explore the significance of DfMA in the context of façade architecture, shedding light on its advantages and impact on the industry.
Having spent more than a decade and a half immersed in the intricacies of façade design, engineering, testing, and inspection, I have witnessed firsthand the evolution of industry practices. The challenges posed by complex architectural visions, stringent performance requirements, and the need for sustainable solutions have spurred the exploration of innovative methodologies such as DfMA.
DfMA is a methodology that focuses on optimising the design process by integrating manufacturing and
assembly considerations early in the design phase. In façade design, this approach holds immense potential for streamlining the construction process, enhancing efficiency, and ensuring a higher level of quality in the final product.
One of the primary advantages of DfMA in façade design is the seamless integration of manufacturing and assembly considerations from the early stages of the design process. Traditional approaches often involve
a sequential progression from design to manufacturing and finally to assembly, leading to potential inefficiencies and rework. DfMA, on the other hand, encourages collaboration between designers, engineers, and manufacturers right from the outset.
This integrated approach allows for a more holistic understanding of the project, fostering better communication and coordination among stakeholders. By identifying potential manufacturing and assembly challenges early in the design phase, the likelihood of costly revisions and delays is significantly reduced.
Over the years in façade engineering, I have come to appreciate the precision required to meet the demanding performance criteria of modern architectural façades. DfMA facilitates a more meticulous engineering process by considering manufacturing constraints and assembly requirements upfront. This ensures that the final product aligns seamlessly with the intended design while meeting performance standards.
Furthermore, DfMA enables the use of advanced technologies such as parametric modeling and digital simulation to refine and optimise the design iteratively. This iterative process allows for continuous improvement, leading to façades that not only meet but often exceed performance expectations.
The façade testing and inspection have instilled in me a deep appreciation for the critical role these processes play in delivering high-quality façades. DfMA, by virtue of its integrated approach, contributes significantly to quality assurance by addressing potential issues before they manifest in the physical construction.
Through virtual simulations and prototyping, DfMA allows for thorough testing of the façade’s performance and constructibility. This proactive approach minimises
the likelihood of post-construction issues, reducing the need for costly retrofitting and ensuring that the façade functions as intended from day one.
In the current architectural landscape, sustainability is a nonnegotiable aspect of any design. DfMA in façade design aligns seamlessly with sustainability goals by minimising material waste, optimising energy efficiency, and reducing the overall environmental impact of construction.
By considering the entire lifecycle of the façade - from manufacturing to assembly to eventual dismantlingDfMA facilitates the development of sustainable solutions. This approach can be essential in meeting the growing demand for environmentally conscious architecture and aligns with global efforts to reduce the carbon footprint of the construction industry.
As I reflect on my years of experience in façade design, engineering, testing, and inspection, the adoption of DfMA emerges as valuable in the industry. The integration of manufacturing and assembly considerations from the inception of a project has the potential to revolutionise the way we approach façade design, fostering efficiency, precision, and sustainability.
The journey from conceptualising a façade to its realisation is intricate, and DfMA provides a roadmap for navigating this complexity with finesse. As the industry continues to evolve, embracing methodologies that enhance collaboration, optimise processes, and deliver high-quality, sustainable solutions becomes paramount. DfMA, with its holistic approach, stands as a testament to the evolution of façade design, ensuring that our architectural visions are not only realised but also endure the test of time with excellence.

CHAYOT KIRANANTAWAT
Senior Lighting Designer, Glint Lighting Design
• How would you explain the role of façade lighting in enhancing the aesthetics and functionality of a building?
Façade lighting is inseparable from the architectural façade itself. It renders the nighttime perception and identity
of the façade forms and elements to appear as per the architects' vision. Without lighting, the architecture would appear dark and unnoticed, as its existence and beauty cannot be appreciated at night. Lighting highlights the aesthetics of the building materials and colours. It also picks up different moods and reinforces statements of the architecture that do not appear during the day and even conveys messages to communicate with the users. In some projects, a generous amount of glass façade allows the interior lighting out and contributes to the façade lighting expression. Therefore, the perceived façade lighting is precisely what is curated inside the architecture. Intense collaborations between various parties are required to devise a good façade lighting scheme.
• How do you approach the creative aspects of designing a façade lighting system?
The creativity of the façade lighting concept may come from many inspirations. Still, it must be based on or developed from the nature of the projects and the architectural intents. First, studying and thoroughly understanding the designed façade intent of use and construction details is essential, as each project has different conditions and requirements. A good façade lighting design needs to respond closely to those intents and requirements while being well-integrated into the façade details. Close collaborations with the architects or façade consultants are also required to achieve a seamlessly integrated façade lighting solution. Additional lighting concepts may be implemented to extend the creativity and nighttime experiences. Façade lighting can either emphasise the building's look as seen during the daytime or completely alter its day and night identities as time changes.

• What factors do you take into account to ensure the longevity and sustainability of a façade lighting installation?
The first part is lighting equipment selection. Even though LED light sources nowadays have considerably long life spans, different world locations have different climates. It is hot in the UAE and dusty due to sandstorms, and rain is scarce, while in Southeast Asia, the weather is hot, humid, and always rainy. Since façade lighting is to work with outdoor equipment, the selection must be carefully made from reputable and reliable brands with a suitable IP rating and other related parameters to withstand the local climate. Maintenance is also a crucial part. Collective discussions with the architects and the design team are required to determine the detailed integration, installation heights, and feasible locations for maintenance.
• What are the latest trends and innovations in façade lighting?
Due to drastically increasing awareness of the environment, symbiotic relationships, and human wellness, the current façade and exterior lighting trends tend to do with decreasing light pollution, reclaiming dark

glare, facing down to mitigate the upward obtrusive light into the sky, and using warmer colour temperatures and suitable optics to prevent light spills and trespass. Dimming control is convinced for the ability to tone down light levels at night and, finally, to light only when and where required. Carefully considered façade lighting design schemes also help reduce the light trespass into the building interiors, which can abruptly impair a good night's sleep.
• Are there specific technologies or practices you favour for achieving energy-efficient façade lighting?
LEDs have become a standard practice as light sources with considerably long hours of life. The technologies are so advanced that many manufacturers can develop products with higher energy efficiency year by year. As lighting designers, we are also responsible for illuminating only where the light is needed, carefully reviewing the light fixtures' use, and pursuing international and local standards to minimise the power density where possible. Lighting control systems, such as dimming and timer control, are strongly recommended for façade lighting. This is not only for the flexibility to balance the lighting effects but also to provide an opportunity to dim down or turn off the lights when not required.
• Could you please elaborate on the use of façade lighting as a marketing factor (creating brand names, promotional images, and advertisements through lighting on façades)?
There are many approaches to delivering messages via the façade design and façade lighting depending on the energy and monetary budgets and design intents. Wall washers can help illuminate and make the façade graphics visible against the darkness. Integrated LED strips behind the signage di-cuts delineate perimeter lighting halos around the logos. Bespoke graphic lightboxes provide an evenly lit advertisement. Alternatively, gobo projectors can establish attentiondrawing static or moving images on the façade, transforming canvas-like plane façade surfaces into a stunning feature. Various kinds of media façade light fixtures, from static white colour temperatures to dynamic tunable white or colour changing, can be
implemented with lighting control to create a vigorous statement for marketing on the façade. This approach can provide more flexible and dynamic messages while adorning the façade with visual spectacles. Still, it may come with a reasonably higher budget and level of workmanship and collaboration on site.
• What is the impact of façade material on lighting?
Both façade materials and colours have a significant impact on lighting effects. Scientifically, lighter colours provide more lighting reflectance, while darker colours absorb light more. Light also appears more prominent on matte materials without leaving the reflection of the light sources on the surfaces. On the contrary, we usually see more reflection and less lighting effects on reflective ones. Transparent materials, like glass, are different as they allow the
light to transmit through themselves, while opal or translucent ones diffuse the light to glow. In practice, the façade material palette will affect how we light the façade and determine the lighting details. Façade materials with textures and patterns are also a great source to be illuminated. Interesting textures will react with the light uniquely.
• Can you share any strategies for minimising maintenance costs over the life of a lighting installation?
Understanding the selected lighting equipment's properties, advantages, and disadvantages is required. The installation locations significantly influence how we choose the lighting equipment. In many cases, the light fixtures must be installed on a high level that is difficult to maintain. The lighting selection must be suitable for the harsh outdoor climate and reliable enough not to fail repeatedly. Proper technical installation per the manufacturer's instruction is also a forefront consideration to ensure the fixtures last their entire life span. Sometimes, using the fixtures with remote drivers at an easily accessible indoor location facilitates maintenance and minimises heavy façade maintenance equipment use.
• With a growing focus on sustainability, how do you incorporate eco-friendly practices into your façade lighting designs?
The sustainability aspect must be carefully considered early in the design stage and regarded as a regular practice for every project. While a lighting designer aims to establish the desired lighting effects, high-efficiency lighting fixtures must be considered to achieve the optimum lighting output with minimised energy consumption. Adopting stringent global lighting standards, like LEED certifications, etc., is vital in regulating the lighting power budget for a façade lighting project. Also, using light fixtures with long life expectancy with correct installations, such as proper wiring and the right type of drivers, helps maximise the fixtures' age and, therefore, minimises electronic waste from
spoiled light fixtures and reduces the maintenance energy and wastes.
• Where do you see the future of façade lighting heading?
Predicting the future of façade lighting is challenging as the lighting technologies advance daily. LED light sources are improved to become of closer quality to the natural sunlight while consuming less energy. State-ofthe-art lighting control products are launched to facilitate flexibility in regulating façade lighting. This is an anticipated opportunity for façade lighting to be made friendlier to our world. I assume the façade lighting trends will accompany the façade design development direction, and I hope it will provide opportunities to design progressively more "human and environment"- caring manner soon. This will add up to reimagining the roles of lighting designers from now on.
In the realm of architectural design, façade lighting emerges as a pivotal element, not merely illuminating structures but orchestrating a harmonious blend of aesthetics and functionality. Beyond its practical role in providing visibility, façade lighting serves as an artistic tool, transforming buildings into captivating landmarks. Creative ingenuity is paramount when designing façade lighting systems, necessitating a delicate balance between form and function.
One of the most vulnerable aspects of building design is the façade.

Role of Façade Lighting in Enhancing the Aesthetics and Functionality of a Building
Mohammed Yaseen Ali, THE LIGHT DOCTOR quotes a famous line of Klaus-Jürgen Maack, “Light is the fourth dimension of architecture”.
Whenever we invite lighting on any architectural element, it enhances the beauty, versatility and prominence of those elements. Similar can be said about the Façade of any building. But it does not only end there, especially when it comes to façade lighting. Because a good light increases the prestige of the building, makes it catchier and hence invites people through its doors, thereby increasing a buildings purpose and functionality. In addition, a good façade lighting, provides a sense of safety and comfort, with indirect lighting spilling onto the walkways and providing an overall city vibe. Hence in my view façade lighting is an important knowledge aspect for a lighting designer.
Façade lighting enhances a building’s aesthetics by highlighting architectural features, creating visual interest, and reinforcing brand identity. It also serves functional purposes, improving safety and wayfinding. The use of energy-efficient LED technology contributes to sustainability goals. Overall, façade lighting transforms a building into a visually striking and functional structure, says Sandeip Anand, Director, AIMS Pvt. Ltd.
Amal Ibrahim, Lighting Design Specialist & Consultant, Amal Ibrahim Lighting Design Service explains façade lighting plays a crucial role in enhancing both the aesthetics and functionality of a building. Here are some of the key ways it achieves this:
Aesthetics:
• Draws Attention to Architectural Details: Façade lighting enhances the visual appeal and fascination of architectural features like columns, arches, sculptures, and textures, particularly at night.
• Adding Dimension and Depth: Façade lighting enhances a building’s character and depth by strategically arranging light and shadow, resulting in a more vibrant and aesthetically pleasing façade.

Façade lighting serves as a dynamic design element, elevating both the aesthetics and functionality of a building. Aesthetically, it enhances architectural features, creating visual interest and a distinct identity, especially during evening hours. Functionally, well-designed lighting creates identity, contributing to a building’s holistic and purposeful integration into its surroundings, believes Krishnakanth, Lighting Design Engineer, UNILIGHTS.
Façade design is one of the most challenging sciences of lighting design. There is no one rule all for designing façade lighting, neither are there fixed standards when
it comes to façades. “I have learned to play with light and shadow, to enhance the architectural elements of any façade. My approach is a mix of what my teachers taught me, and what I could learn from the stalwarts of our industry. The focal point of my creative process is to highlight the prominent parts following with an embodiment of simple features and ending it with small touches to enhance the look. Moreover, I have noticed that most of architects and lighting designers take their inspirations from the name, theme, or idea of the building itself, and then work on to create a matching lighting design. These have proven to be aesthetically beautiful and even the clients love them”, says Yaseen Ali.
Sandeip believes that approaching the creative aspects of façade lighting involves understanding architectural features, considering the purpose and desired atmosphere. Choose a complementary colour palette, explore dynamic lighting scenarios, and integrate the latest technologies for versatility. Focus on creating depth through layered lighting and consider the environmental impact with energy-efficient solutions. Collaboration with stakeholders and seeking feedback throughout the process ensures a holistic and effective design.
Amal suggests following aspects that should be considered before starting a façade lighting design of a building:
• Looking for architectural features such as Entrances, windows and how many of them are used in the design.
• Looking for the type of materials being used in the Façade of the building
• Looking for the most featured distinguished elements of a façade design
• Looking for a common language model that has a repetitive type of architectural element to highlight on.
• Considering the type of Façade Design style, whether it is modern, neo-classical or classical design
• Looking for the surroundings environment, whether the building is located in a brightly illuminated or poorly illuminated area.
The creative side of developing a façade lighting system requires a careful blending of knowledge of technology and artistic sensibility. Comprehending the architectural context, client goals, and intended atmosphere is crucial. “I experiment with fixture locations, colour temperatures, and lighting strategies to draw attention to important details and produce a visual story that harmonises with the architecture of the structure. Working together with architects and engineers helps a lot in incorporating into the entire design, producing an eye-catching and distinctive lighted façade”, says Krishnakanth
According to Yaseen Ali , with the advent of LED technology and rampant implementation of these luminaries, the lifetime of the luminaries is a given. So mostly my focus is on the IP rating, IK rating, and the durability of the drivers in different outdoor temperatures. Apart from these aspects, now a days we are also focusing on the Dark Sky Association compliance for almost all new projects. Which has significantly transformed the way we look at lighting and design.
To ensure the longevity and sustainability of a façade lighting installation, key factors include selecting durable materials resistant to weathering, implementing energy-efficient technologies, conducting regular maintenance to address wear and tear, and considering the environmental impact to minimise light pollution and energy consumption, notes Sandeip
Amal opines that to guarantee the durability and sustainability of a façade lighting installation, a comprehensive strategy is needed, considering factors such as:
• Lighting fixture selection: opt for high-quality fixtures with waterproof & weatherproof materials like marine-grade stainless steel or anodised aluminum, they should resist corrosion, UV degradation, and extreme temperatures.
• LED technology: Choose LEDs with over 50,000 hours of lifespan and consider factors like lighting efficacy, color temperature, and CRI for optimal impact.
• Thermal management: Select fixtures with efficient heat dissipation mechanisms to prevent overheating and premature LED failure, and utilise separate LED drivers to extend fixtures’ lifespan.
• Positioning of lights: Fixtures should be positioned carefully to reduce glare, light trespass, and energy waste. For fine control, use aiming techniques, louvres, and shielding.
• Power supply and control: Implement efficient drivers and control systems for dimming, scheduling, and scene creation, while considering integration of sensors for daylight harvesting and occupancy detection.
• Access to maintenance: The installation should be designed for easy maintenance, replacement, and cleaning of fixtures, minimising the need for scaffolding or special tools.
• Mounting hardware: Choose corrosion-resistant bolts, anchors, and brackets to withstand the elements and prevent structural damage.
• Wiring: Use UV-resistant and weatherproof cables suitable for outdoor environments. Consider direct burial options for long-term reliability.
• Light pollution: To protect nighttime wildlife and comply with regional regulations, reduce upward light emissions by using downward-facing shields and fixtures.
• Energy efficiency: Prioritise energy-saving techniques like daylight harvesting, occupancy sensors, and dimming to reduce energy use and its environmental impact.
• Material sourcing: To reduce transportation emissions and promote sustainable practices, use locally or recycled materials.
• Maintenance plan: Establish a regular cleaning and inspection schedule to extend the life of fixtures and address possible problems early.
• Upgradability: The system should be designed for future updates, ensuring flexibility with evolving technologies by considering modular parts and easily accessible replacements.
• According to Krishnakanth, ensuring the longevity and sustainability of a façade lighting installation involves a comprehensive consideration of several factors.
• The selection of high-quality, durable fixtures and materials is critical.
• Prioritise energy efficiency by employing LED technology and implementing intelligent control systems to optimise usage.
• Regular maintenance schedules and weatherresistant designs further contribute to the system’s longevity, while a thoughtful approach to light pollution minimises environmental impact.
• Façade lighting installations that endure aesthetically and functionally over the long term.
Recent trends in façade lighting include the widespread adoption of dynamic lighting systems with programmable LEDs, the use of interactive and responsive lighting designs, integration of sustainable and energy-efficient technologies like solar-powered systems, and advancements in smart control systems enabling more sophisticated and customisable lighting effects, believes Sandeip
Amal explains that the world of façade lighting is constantly evolving, with new trends and innovations emerging all the time. According to her here are some of the hottest happenings:
• Interactive façades: For example, a building façade might ripple with light as you walk by, or change color based on the current weather.
• Pixelated façades: Envision a building front that transforms into an enormous screen that displays animations, artwork, or even data visualisations displayed in real time.
• Projection mapping: This technology takes façade lighting to a whole new level by using projectors to cast images, patterns, or even 3D animations onto building surfaces. The possibilities are truly limitless, from creating mind-bending illusions to transforming buildings into interactive storytelling canvases.
Krishnakanth believes that the latest trends and innovations in façade lighting are combining technology and environmentally friendly design are coming together. Automation and smart sensors enable dynamic lighting control systems, which provide flexible and economical solutions. It is becoming more and more common for builders to create immersive experiences and adjust to different moods by using RGBW LEDs for color diversity. To reduce light pollution, there is also an increasing focus on using eco-friendly materials and implementing dark sky-friendly methods. Façade lighting trends are generally pushing the envelope and providing a pleasing harmony between practicality, aesthetics, and environmental responsibility.
“Control-ability is one of the technological benefits that I tend to focus on, as this helps to control the luminaries efficiently and actively. Whether its DMX, DALI, KNX etc. any and all protocols helps in valuing the energy
benefits we get from dimming down the luminaries, timing the luminaries and even enhancing the lights for special activities. For many of my recent projects we have been partnering with brands like Schreder, Griven, Siteco etc. to provide energy efficient dimmable solutions to our clients using DALI technology”, says Yaseen Ali
Sandeip favours the use of LED technology for its energy efficiency, longevity, and versatility in achieving dynamic lighting effects. Additionally, smart control systems that enable precise management of lighting levels and schedules contribute to energy conservation in façade lighting installations.
Amal says, “Of course! I have a strong interest in energy efficiency as an ecologically aware language model, especially when it comes to façade lighting. I think the following practices and technologies are really promising”:
• The obvious winners are LEDs, which have a long lifespan (50,000+ hours), excellent efficiency (80–100 lm/W), and little heat generation.
• Fiber Optics systems
• Motion sensors and occupancy detectors:
• Dimmers and smart lighting control systems
• Solar panels
Practices:
• Targeted lighting where you highlight specific architectural elements instead of bathing the entire façade in light.
• Uplighting
• Choose fixtures with minimal up-light and shielded bulbs to minimise light pollution and protect the night sky.
• Regular maintenance: To guarantee maximum efficiency and avoid wasteful energy waste, clean fixtures and replace lamps as soon as possible.
Certainly, achieving energy-efficient façade lighting is a priority in contemporary design. I favour the integration of LED technology for its high efficiency and longevity, coupled with advanced control systems such as dimming and scheduling to optimise energy usage. Additionally, utilising smart sensors and automation allows for adaptive lighting based on ambient conditions, further enhancing efficiency. Embracing these technologies, along with a focus on thoughtful fixture selection and placement, enables me to create sustainable and visually compelling façade lighting designs, says Krishnakanth
Yaseen Ali says façade is like an empty canvas whether to highlight the building itself, or to catch up on the trend of media façade and I would argue - marketing is the main purpose of Façade lighting. Because all the famous places like the Clock tower of Makkah, The Empire state building, or even the skyline of Dubai, all are prominent because of Lavish and signature lighting design done on their façades. Which makes sure that they remain prominent even at night. Adding lighting to an already exquisite façade is like adding cherries on top of an already delicious cake - It only adds to the flavor and experience. With a small investment towards a good lighting, the clients can expect huge returns as it immediately highlights the building in the rows of mega structures. Additionally, a good lighting design portrays elegance and opulence, both qualities of a charming and attractive client or location.
Façade lighting serves as a compelling marketing tool by transforming buildings into dynamic canvases for brand promotion. Businesses can enhance brand visibility through custom lighting designs, incorporating colors and logos. This approach creates a distinctive identity, setting the brand apart and enabling storytelling through light. Façade lighting is adaptable to seasonal
campaigns and events, providing an engaging and shareable experience for social media. Iconic, well-lit buildings become landmarks, contributing to positive brand image and community engagement. Additionally, advanced technologies like projection mapping offer immersive experiences for product launches or storytelling campaigns. In essence, façade lighting goes beyond illumination, becoming a visual and interactive medium for marketing and brand promotion, opines Sandeip
Amal believes that façade lighting has evolved into a powerful marketing tool, enabling businesses to create eye-catching displays that transform buildings into billboards, brand ambassadors, and storytelling platforms. It builds a brand identity using logo illumination and themed lighting, crafts promotional images through interactive lighting and storytelling with light, and displays ads that are entertaining using product projection and holographic displays.
Façade lighting turns buildings into dynamic brand assets, which makes it a potent marketing tool. I use architectural elements to strategically illuminate brands in a way that makes them memorable and recognisable. Promo photos and ads are improved by this visual storytelling, which offers a distinctive and alluring visual language that supports the brand’s messaging. Façade lighting becomes a powerful instrument for creating and marketing a brand’s distinct identity in the architectural landscape, whether through color, dynamic lighting sequences, or specific projections, says Krishnakanth
Yaseen Ali says “as a lighting designer, I actually look at this from the other way – Whats the effect of light on different materials. For example, glasses are always tricky to design as light passes through such material easily and hence requires either more focus or an entire avoidance of designing areas with glass. On other hand a solid brick will be less of a focal point for design, compared to a textured area of façade, as texture adds drama and lighting will enhance those aspects. The same goes with metal and fabrics for example, metals being shiny they tend to behave very differently when compared with fabrics. Even the tone and colors make a huge change in how the light will behave on such materials. Not to forget the finishing of the paints. So, considering these aspects are important for a professional lighting design”.
Sandeip believes that the choice of façade material significantly shapes the impact of lighting on a building. Highly reflective materials, like glass or metal, can enhance the luminous effect by bouncing light. Translucent materials, such as certain types of glass, create a diffused and soft illumination. The texture and pattern of materials influence the interplay of light and shadow, adding depth. The colour of façade materials affects brightness and colour rendition, with light-coloured surfaces appearing brighter. Transparent or mesh-like materials enable dynamic lighting displays or projection mapping. Consideration of material durability and maintenance is crucial for sustained lighting effectiveness. Overall, the façade material plays a crucial role in achieving the desired visual impact and functionality of lighting on a building
Amal notes that the façade material of a building has a significant impact on how light interacts with it, affecting both the aesthetics and functionality of the lighting design. Here’s how: reflectivity, transparency/opacity, texture and color characteristics of Façade materials should be considered.
The choice of materials and lighting methods can significantly impact the lighting effect of a building. Materials like brick and wood can create a rustic atmosphere, while glass and metal can create a modern, minimalist style.
Lighting methods adjust to the characteristics of the materials. Backlighting draws attention to the translucency of glass, while grazing light accentuates the roughness of rough surfaces.
One issue is energy efficiency. More illumination may be required for darker materials, although light pollution and trespassing can be reduced by selectively illuminating reflecting surfaces.
Climate: Light-colored façades can reflect heat and lower cooling expenses in hot places.
Maintenance: To keep their reflecting qualities, materials like glass need to be cleaned on a regular basis.
The choice of façade material significantly influences the impact of lighting. Different materials interact with light in unique ways, affecting reflection, absorption, and transmission. For example, smooth and reflective surfaces enhance the luminance and create dynamic highlights, while textured or matte materials diffuse light, softening its effect. The color and transparency of materials also play a crucial role, influencing the perceived warmth or coolness of the lighting. As a lighting designer, understanding these material-light interactions is fundamental to crafting impactful and harmonious façade lighting schemes, believes Krishnakanth
It is important not to select a glass with a very high light transmittance as it will have a glare effect. Selecting a moderate light transmittance requirement for residential houses is always advisable. On the other hand, it is highly recommended for storefronts and retail areas have crystal clear glass to showcase the products for sale more clearly for customers, says Fadi.
Ahmed observes, in architecture, glare can be a problem from the windows of an office building or the glass on a lot of cars. Glare on the windshield can make it nearly impossible to read the speedometer at night. A double pane of glazing or louvers helps to reduce this effect by reducing the amount of light that is able to enter through the window.
There is also the Anti-glare glass which has a matte finish on the exterior surface, this finish can be either shiny (light) or dull (dark). It is created by applying a thin layer of transparent material to the surface of the glass. This material can be any number of things including thin metal alloys, coatings, paints, and anodised aluminium. When installed in buildings, this type of glass helps reduce glare from sunlight and artificial light.
With regards to the noise; as mentioned before, the thickness of the glass is important as it determines how resistant your window glass is towards the noise. The thicker the glass, the more resistant and shock resistant it will be. Furthermore, the glass can be laminated with a tough plastic that is both transparent in nature and shatter-resistant.
Finally, to control the heat; we should use highperformance solar glazing on windows, with coatings that are “spectrally selective”, which means they keep the sun’s heat outside but let daylight in.
There’s also photochromic glazing, which changes transparency depending on the intensity of the light (like some sunglasses), and thermochromic glazing, which becomes darker when it is hot, which can also help.
Even thermochromic paints, which absorb light and heat when it’s cold, and reflect it when it’s hot, are being developed.
Yaseen Ali explains, partnering with brands that understand and respect sustainability, cyclability and earth impact is the first step to ensuring the designs are more sustainable. For me, such partnerships remove the hassles of ensuring lesser damage is done to the earth during production of the luminaries itself. With that peace of mind, and armed with LED technology, façade designs can be made more sustainable and eco-friendlier. Another step that I ensure, especially for the projects I am involved till the end is that a proper lighting maintenance guide is provided to the O&M teams. This ensures a longer life for the luminaries, and reduces energy and light losses through the lifetime of the installation.
Sandeip suggests, in designing façade lighting with a focus on sustainability: Consider using energyefficient LED fixtures with longer lifespans and lower environmental impact. Implement intelligent controls like occupancy sensors and timers to optimize lighting based on occupancy and natural light conditions, reducing unnecessary energy use. Integrate daylight sensors to adjust lighting levels based on natural light availability, minimizing reliance on artificial lighting during daylight hours. Incorporate solarpowered lighting fixtures in areas with access to sunlight, harnessing renewable energy and reducing dependency on the electrical grid. Choose fixtures with energy-efficient electronic ballasts to further reduce power consumption. Select façade materials with low environmental impact, considering recycled content and recyclability. Optimise lighting designs to minimise light pollution, directing light where it is needed and using proper shielding. Implement adaptive lighting systems that adjust brightness based on environmental conditions, ensuring efficient energy use. Integrate biophilic design elements into the lighting scheme, fostering a connection with nature. Conduct a lifecycle analysis to evaluate the environmental impact of the entire lighting system, considering manufacturing, transportation, installation, and end-of-life disposal. Source materials locally to reduce the carbon footprint
associated with transportation. Choose manufacturers with sustainable and eco-friendly production practices. Install educational signage near the façade lighting to inform the public about sustainable features, raising awareness and encouraging environmentally conscious behaviour. Design the system to minimise water usage during maintenance activities, such as cleaning, particularly in regions facing water scarcity. By incorporating these strategies, façade lighting designs can contribute to a sustainable & energy-efficient built environment. This approach aligns with global efforts to reduce environmental impact and sets a positive example for responsible and forward-thinking design.
Incorporating eco-friendly practices into façade lighting designs is integral to my approach. Krishnakanth prioritise energy-efficient LED technology, employing fixtures with high lumens per watt ratios. Smart control systems, including daylight sensors and programmable schedules, optimise energy consumption. Additionally, he emphasises the use of recyclable materials in fixture construction and consider the life cycle impact of each component. By minimising light spill and adopting dark-sky-friendly practices, he strives to create façade lighting designs that harmonise with environmental sustainability, ensuring a responsible and aesthetically pleasing contribution to the built environment.
With more and more initiatives being taken to educate leaders and ground work being done by different organisations like DARPA, IESNA, ILDA etc. He sees a more professional & well-balanced future for lighting design itself. Obviously, everyone is adopting LED technology and hence more architecturally accurate lighting design can be offered to the clients, which will lead to a more beautiful future too, believes Yaseen Ali
Sandeip sees that the future of façade lighting is poised for dynamic advancements driven by technology, sustainability, and a desire for interactive urban spaces. Expect smart façades dynamically responding to real-time data, AI optimising lighting efficiency, and projection mapping evolving into intricate visual experiences. Biophilic design elements may mimic natural patterns for calming environments, and AR/VR integration could redefine user experiences. Energy-harvesting technologies may make façades self-sufficient, and transparent solar panels might become commonplace. Data analytics will inform ongoing design adjustments, fostering collaborative urban lighting ecosystems. Façade lighting will likely respond to climate change and environmental factors, adapting to dynamic conditions. Transparent displays and digital signage may integrate seamlessly, while IoT connectivity will enhance monitoring and maintenance. The future promises a harmonious blend of technology, sustainability, and innovative design in façade lighting.
Amal opines that the projection mapping is already transforming buildings into dynamic displays, but the future promises even more. Imagine façades that change in real time to reflect traffic patterns or the weather, or that turn into interactive galleries for public art, neighborhood gatherings, or even customised welcomes. Material Innovation: Imagine façades that not only emit light but also generate it through integrated solar panels or even bioluminescent materials. Increase Hyper-personalisation and Connectivity by adjust lighting based on individual preferences or even project personalised messages for specific passersby. Putting sustainability first: Imagine façades that have advanced technologies installed to optimise lighting based on occupancy, daylight availability, and even the inhabitants’ mood. Imagine a seamless integration of lighting systems with security,
HVAC, and interior illumination, ensuring compatibility with the built environment.
Krishnakanth says that the future of façade lighting holds exciting possibilities at the intersection of technology, sustainability, and artistic expression. I foresee continued advancements in smart lighting systems, integrating AI for adaptive and responsive designs. Energy-efficient solutions, such as solarpowered and low-impact technologies, will likely become more prevalent. Moreover, there will be a growing emphasis on dynamic, interactive lighting experiences that engage with the public and adapt to changing environmental conditions. As the industry evolves, the future of façade lighting promises to be a dynamic fusion of innovation, sustainability, and captivating design narratives.
Façade lighting serves as a pivotal element in elevating both the aesthetic appeal and functionality of a building. Embracing a creative approach to design, practitioners consider factors like longevity, sustainability, and the impact of façade material on lighting. The integration of cutting-edge technologies for energy efficiency aligns with the latest trends, while strategic use of lighting as a marketing tool amplifies brand identity. Moreover, minimising maintenance costs and incorporating eco-friendly practices align with the growing emphasis on sustainability. As the industry evolves, the future of façade lighting lies in seamlessly blending innovative technologies, sustainability, and artistic expression to illuminate and define the architectural landscape.

In a bid to erase its notorious past, Orchard Towers, a longstanding landmark in Singapore, is undergoing a comprehensive twoyear makeover. Once infamous for its association with dubious activities, the iconic building is set to emerge as a family-friendly destination, shedding its shady reputation.
The ambitious rejuvenation project encompasses a complete overhaul,
featuring a new external façade and cladding. Additionally, there is a deliberate shift in the tenant mix to attract businesses with a more wholesome appeal. The management is actively seeking family-friendly tenants to replace the nightlife outlets that faced closure earlier this year due to licensing issues.
Despite the ongoing transformation, Orchard Towers faces challenges in distancing itself from its checkered past. Reports of questionable activities persist in and around the vicinity, indicating skepticism and resistance to the building’s intended metamorphosis.
As of now, the retail occupancy of the 53-year-old building hovers around 70%, presenting a quieter atmosphere compared to its modern neighbors along Orchard Road. The strategic move to attract family-oriented businesses, including furnishing stores, pharmacies, eateries, tuition centers, and dance studios, aims to reshape the building’s image and appeal to a different demographic.
Orchard Towers’ journey towards a more respectable and welcoming space is met with both anticipation and skepticism, as the management strives to redefine its identity in the vibrant heart of Singapore.

In a groundbreaking move aimed at enhancing emergency preparedness, Toronto-based architecture studio RDHA has revealed its latest creation—a stateof-the-art emergency generator tower designed for Metrolinx, the agency overseeing public transit in Toronto. This cutting-edge generator, strategically positioned
to power Toronto’s iconic Union Station during emergencies, seamlessly integrates with the historical landscape.
Situated adjacent to a defunct signal tower constructed in 1930 for the Canadian Pacific Railroad, the new generator building pays homage to its historic neighbor, designed by John Wilson Orrock and renowned for its Italianate details. RDHA’s design incorporates subtle cues from the Orrock tower, with horizontal datum lines connecting the two structures.
A scalloped retaining wall serves as a link between the old and new,
maintaining the grade change between track and street levels. Inspired by arched forms found on the historic tower, the retaining wall is set to be transformed into a green space along the rail tracks, adding aesthetic appeal and ecological value.
Internally, the generator embraces sustainable practices with energy-efficient LED lighting, daylight sensors, and temperature optimization systems, catering to the needs of municipal employees utilizing the space. The building’s structural integrity is ensured by a combination of concrete piles and walls, with a steel frame supporting both the walls and façade panels.
In a triumph of architectural innovation, Foster + Partners has secured victory in an international competition to conceptualise the new terminal for Abha Airport in Saudi Arabia’s Aseer Region. The design, inspired by the nearby Rijal Almaa village, marks a paradigm shift in airport architecture by transforming the terminal into a series of interconnected humanscale clusters, outdoor courtyards, and walkways.
Stefan Behling, Head of Studio at Foster + Partners, described the design as a “complete reinvention of the airport,” integrating traditional Aseeri details, local materials, and
terraced landscaping. The terminal guides passengers through inviting, human-scale spaces, connecting them with green courtyards that embrace the open environment. This pioneering approach sets a new benchmark for airport design, prioritising fresh air, greenery, and natural light to enhance the travel experience.
The modular form of the terminal is strategically arranged in clusters between the drop-off zone and the apron, utilising varying heights and tapering buildings to reflect the distinctive architectural character of the Aseer Region. This modularity ensures flexibility,
enabling the airport to expand efficiently in response to increasing demand.
Responding to the region’s climate, the design optimises natural ventilation by strategically placing masses to harness prevailing winds. Solid stone walls and diffused daylighting contribute to maintaining comfortable and cool internal spaces. Foster + Partners’ winning design not only celebrates the beauty of the Aseer Region but also introduces a groundbreaking typology in airport architecture, blending tradition with contemporary functionality.
In a bold architectural move, Zaha Hadid Architects has revealed their design for “Masaryčka,” a high-rise marvel located adjacent to one of Prague’s major railway stations.
