Façade Design

Modern and Sleek Shopping Mall

Façade Design: A Blend of Aesthetics,

Functionality, and Sustainability

The façade of the modern shopping mall plays a crucial role in defining its architectural identity, serving as both an aesthetic and functional element. A welldesigned façade not only creates an inviting entrance for visitors but also offers protection from the elements, facilitates energy efficiency, and reflects contemporary design trends. In this context, the modern shopping mall façade, with its sleek, linear appearance, coupled with a dynamic cantilevered canopy, metal louvred screens, and

sophisticated lighting systems, stands as a testament to advancements in both design and sustainability. This design approach harmonises beauty, utility, and environmental consciousness.

CURVED CANTILEVERED CANOPY: A BOLD ARCHITECTURAL STATEMENT

One of the most striking features of the shopping mall façade is the curved cantilevered canopy, which immediately captures attention. This architectural element extends beyond the building

structure, creating a sense of openness and fluidity. The curve of the canopy adds an element of dynamism and elegance, breaking away from rigid designs. It serves both aesthetic and functional purposes: visually, it enhances the mall’s contemporary appeal, giving it a sleek and futuristic look, while practically, it provides shelter for pedestrians and visitors, protecting them from the sun or rain.

The cantilevered design further symbolises innovation and forward-

thinking architecture. Suspended with advanced engineering techniques, this canopy employs lightweight materials such as carbon fibre, glass, or high-performance composites that not only keep the structure light but also contribute to its overall sustainability. The clean, curving form contrasts with the sharp lines of more traditional façades, allowing the mall to stand out as a modern hub in an urban landscape.

METAL LOUVRED SCREENS: BALANCING LIGHT AND PRIVACY

The metal louvred screen is another key component of the façade design that adds aesthetic value. Its sleek, modern appearance enhances the contemporary look of the mall, creating a subtle interplay of shadows and light that changes throughout the day, contributing to the building’s everevolving character.

Beyond this, metal louvres create an intricate visual texture on the façade, evoking a sense of depth and movement.

The screen can also incorporate different finishes, such as brushed steel, anodised aluminium, or powder-coated metal, allowing for customisation based on the mall’s branding and surrounding architecture.

LINEAR FAÇADE: SLEEK AND STREAMLINED

The overall linear façade design embodies the essence of modern minimalism. Clean horizontal and vertical lines define the building’s exterior, emphasising the sleekness of the structure while providing a visual connection between different sections of the mall. This streamlined design ensures that the building maintains an open, airy feel while reflecting the design sensibilities of contemporary architecture.

The linearity of the façade also serves as an organising principle for the entire building. It allows for the seamless integration of other elements such as windows, doors, signage, and branding, contributing to the mall’s overall coherence. By keeping the façade free

of excessive ornamentation, the design elevates the architectural integrity of the space, making it timeless and adaptable.

The linear approach also facilitates the effective use of materials, allowing for consistency and balance across the entire structure. Glass, steel, concrete, and stone are often used in combination to create contrasts that further emphasise the modern aesthetic. Large panels of glass, for instance, allow natural light to flood the interior, creating a welcoming and vibrant atmosphere. They also offer an opportunity for shoppers to engage with the exterior landscape, blurring the boundaries between inside and outside.

LIGHTING DESIGN: ENHANCING THE FAÇADE’S DRAMATIC PRESENCE

Lighting plays a crucial role in accentuating the modern design of the shopping mall façade. Strategic placement of lighting elements can transform the mall’s appearance from

The cantilevered canopy, in particular, is illuminated to accentuate its bold curve. Lighting placed along the underside of the canopy highlights its architectural grace, casting dramatic shadows and making it visible from various vantage points.

SUSTAINABILITY: A GREEN APPROACH TO MODERN ARCHITECTURE

Incorporating sustainable design principles into the shopping mall façade ensures that it not only serves its function as a commercial hub but also contributes to the health and well-being of the environment. The façade’s design maximises natural light intake, minimising the need for artificial lighting and contributing to energy savings.

Furthermore, the materials used in the façade construction include recycled, locally sourced, or ecofriendly components, reducing the environmental impact of transportation and extraction. Low-

VOC (volatile organic compound) paints and finishes are proposed to ensure air quality both inside and outside the building.

The incorporation of green roofs or vertical gardens, though not directly part of the façade, is another way to enhance the sustainability of the mall’s exterior. These green spaces contribute to biodiversity, absorb rainwater, and reduce the heat island effect in urban areas.

CONCLUSION: THE FUSION OF INNOVATION AND SUSTAINABILITY

A modern and sleek shopping mall façade, with its dynamic cantilevered canopy, metal louvred screens, linear form, and sophisticated lighting, represents the perfect marriage of cutting-edge design and sustainable practices. The façade not only enhances the mall’s aesthetic appeal but also optimises functionality and energy efficiency, providing a comfortable and engaging environment for shoppers while reducing the building’s environmental impact. This approach ensures that the mall stands as a landmark of modern architecture, embodying the values of sustainability, innovation, and timeless design for years to come.

Beyond Aesthetics: Choosing the Perfect Façade for Performance & Sustainability

As the building envelope plays a critical role in overall building performance, investing time and resources in selecting the right façade and fenestration systems will pay dividends in terms of energy efficiency, occupant comfort, and architectural excellence for years to come. Several key factors need to be considered to ensure the selection meets both aesthetic and functional requirements.

AESTHETIC APPEAL & ARCHITECTURAL INTENT

The façade should align with the architectural vision and design of the building, enhancing its overall appearance while reflecting its purpose and style. It must seamlessly integrate with the overall building design, including structural elements, MEP systems, and interior layout. Choosing appropriate colours and finishes that complement the building’s design and

surrounding environment is equally important.

PERFORMANCE CHARACTERISTICS

Energy efficiency is crucial in façade selection, with materials that improve

insulation and reduce energy consumption playing a key role. Lower U-values indicate better insulation, while the Solar Heat Gain Coefficient (SHGC) measures how much solar radiation passes through the glazing. A well-designed façade must prevent air and water infiltration to protect the building’s interior and prevent structural damage. Materials should also be durable and weather-resistant, capable of withstanding UV exposure, temperature fluctuations, and moisture. Ease of cleaning plays a crucial role, and durable options such as porcelain slabs or engineered façade materials like HPL are increasingly popular for their resilience. Acoustic performance is another important factor, particularly in environments where noise intrusion must be mitigated, such as hotels or hospitals near railway lines.

SUSTAINABILITY

The environmental impact of façade materials must be considered throughout their lifecycle - from production to disposal—to align with green building practices. For example,

using sandstone from a nearby quarry can reduce transportation emissions. The recyclability of materials is another key factor, with options such as aluminium and glass being highly reusable. Selecting façade and fenestration systems that contribute to achieving green building certifications like GRIHA, LEED, BREEAM, or other local standards is also essential.

MAINTENANCE REQUIREMENTS

Low-maintenance materials that are stain-resistant, fade-resistant, and easy to clean help reduce long-term upkeep costs, particularly in climates with extreme weather conditions. Additionally, the availability of replacement parts and ease of repair should be considered. Evaluating the expected lifespan of different systems and materials about the building’s intended lifecycle ensures long-term durability.

STRUCTURAL COMPATIBILITY

The structural integrity of the façade must be able to withstand wind loads, seismic activity, and other external forces, making proper engineering and material selection paramount. The weight of façade materials also affects structural design and installation costs, with lighter materials easing the load on structural elements and simplifying

the installation process. Furthermore, the chosen materials should be compatible with existing building systems and comply with local building codes regarding performance standards.

SECURITY AND SAFETY

Fenestration systems should provide adequate security against forced entry while also meeting safety standards, particularly in commercial applications

with high traffic. Fire safety is another crucial factor, with façade materials and systems needing to meet prescribed fire resistance requirements to ensure occupant safety, as per EN, ASTM, or BS codes.

COST CONSIDERATIONS

While initial costs are important, it is crucial to consider the total cost of ownership. Balancing upfront investment with long-term benefits and

performance can help optimise financial decisions. Potential energy savings from high-performance systems should be calculated, along with ongoing maintenance and potential replacement costs. Additionally, the complexity and labour requirements for installation should be factored in.

INSTALLATION AND CONSTRUCTION CONSIDERATIONS

The ease of installation can significantly impact project timelines and costs. Prefabricated or modular systems can facilitate faster on-site installation. The structural implications of the façade system’s weight should be evaluated, to ensure compatibility with other building systems and components. The availability of skilled labour for specialised systems is another important factor to consider.

INNOVATION AND SMART TECHNOLOGIES

Modern façade systems increasingly incorporate advanced technologies for improved performance and user comfort. Kinetic glazing, for example, allows for adaptive solar control by acting as shading when the sun is at its peak. Building-integrated

photovoltaic (BIPV) systems can be explored for energy generation. Smart control systems that integrate with building management systems allow for automated adjustments, further enhancing efficiency.

CUSTOMISATION AND FLEXIBILITY

The ability to customise façade and fenestration systems is crucial for unique architectural visions. Manufacturers should be evaluated for their capability to produce non-standard shapes and sizes. A wide range of colour and finish options should be considered to match specific design requirements. Additionally, adaptable systems that allow for future modifications or upgrades provide longterm flexibility.

CONCLUSION

Procuring façade and fenestration systems requires careful consideration of numerous factors, balancing aesthetics, performance, cost, and sustainability. By thoroughly evaluating these key aspects, we can ensure that the chosen systems not only meet the immediate needs of the project but also provide long-term value and performance.

Use of Natural Materials for the Building Envelopes of Urban Projects

The rapid urbanisation of the 21st century has significantly altered the built environment, often at the expense of ecological balance. As cities expand, the materials used in construction play a crucial role in determining not only the aesthetic and structural integrity of buildings but also their environmental impact. We advocate for the use of natural materials in building envelopes for urban projects, ensuring sustainability, durability, and a deep connection to local culture and climate.

THE NEED FOR SUSTAINABLE BUILDING ENVELOPES

Building envelopes, the outer layers that protect structures from environmental elements, are instrumental in regulating energy consumption, providing insulation, and enhancing the aesthetic appeal of urban developments. With the growing concerns over climate change and resource depletion, architects and designers are turning toward natural materials to create more responsible and adaptive urban environments.

ADVANTAGES OF NATURAL MATERIALS IN URBAN PROJECTS

1. Energy Efficiency & Thermal Comfort

Natural materials such as rammed earth, stone, and timber have excellent thermal mass, allowing buildings to maintain stable internal temperatures. These materials absorb heat during the day and

release it at night, reducing the reliance on artificial heating and cooling systems.

2. Reduced Carbon Footprint

The construction industry is one of the largest contributors to global carbon emissions. Using natural materials, which require less processing and energy-

intensive manufacturing compared to synthetic alternatives, significantly reduces the embodied carbon of buildings. Locally sourced materials further minimise transportation emissions, contributing to a greener footprint.

3. Biophilic and Aesthetic Appeal

Natural materials offer a unique tactile and visual appeal that enhances the well-being of occupants. Biophilic design principles emphasise the importance of natural elements in built environments, improving mental health, productivity, and overall satisfaction.

4. Durability and Longevity

Many natural materials, such as stone and clay, have been used for centuries due to their durability. These materials age gracefully, developing a patina that adds character to the urban fabric while reducing the need for frequent replacements or maintenance.

KEY NATURAL MATERIALS FOR BUILDING ENVELOPES

1. Timber

As a renewable and highly versatile material, timber is making a comeback in urban construction. Modern advancements in engineered wood, such as cross-laminated timber (CLT), allow for greater structural strength and fire resistance, making timber a viable alternative to steel and concrete in highrise construction.

Façade Materials

2. Rammed Earth

A time-tested material, rammed earth is gaining popularity in contemporary urban projects due to its excellent thermal mass and low environmental impact. Compressed layers of earth mixed with a stabilising agent create robust walls that naturally regulate indoor temperatures and humidity.

3. Stone

Stone, particularly locally quarried varieties, offers resilience and aesthetic richness. Whether used as cladding or a structural element, stone enhances the longevity of urban buildings while reducing maintenance costs.

Additionally, its high thermal mass contributes to passive cooling and heating strategies.

4. Terracotta and Clay

Terracotta and clay bricks are widely used for their breathability, thermal insulation, and aesthetic warmth. Perforated terracotta panels, often referred to as ‘jaalis’ in South Asian architecture, provide passive ventilation and light filtration, making them ideal for high-density urban environments.

5. Bamboo

Bamboo is emerging as a highperformance, sustainable alternative to traditional materials. Its rapid growth cycle and high tensile strength make it an ideal material for lightweight cladding and façade treatments, particularly in tropical urban regions.

CASE STUDIES OF URBAN PROJECTS WITH NATURAL BUILDING ENVELOPES

1. Integration of Stone and Timber in Residential Towers

In one of our recent projects, we combined locally sourced stone cladding with engineered timber panels to create a dynamic yet sustainable building envelope. This not only reduced operational energy but also enhanced the visual integration of the structure with its surroundings.

2. Adaptive Reuse of Rammed Earth for Mixed-Use Developments

Rammed earth is used in mixed-use urban project. By repurposing excavated soil from construction sites, we minimise waste and promote circular building practices while ensuring climate responsiveness.

3. Terracotta Façades for Office Spaces

Terracotta cladding has been utilised in our corporate headquarters designs to provide passive cooling and daylight optimisation. The result is an energyefficient office space that fosters productivity and well-being.

OVERCOMING CHALLENGES IN USING NATURAL MATERIALS

Despite their benefits, natural materials face challenges in widespread adoption:

• Cost Considerations: While some natural materials can be more expensive upfront, their long-term savings on energy and maintenance outweigh initial investments.

• Regulatory Barriers: Many urban policies still favor conventional materials, requiring updates to building codes to accommodate sustainable alternatives.

• Material Sourcing: The availability of high-quality natural materials can be limited, necessitating sustainable

FUTURE OF NATURAL MATERIALS IN URBAN CONSTRUCTION

As cities strive toward carbon neutrality, the role of natural materials in urban construction will continue to expand. Innovations such as bio-based composites, algae-infused façades, and AI-assisted material optimisation are set to revolutionise the way we design building envelopes. The building industry should remain committed to pioneering solutions that integrate natural materials into modern urban landscapes, ensuring sustainability without compromising on aesthetics or performance.

CONCLUSION

The use of natural materials in building envelopes is no longer an alternative — it is a necessity for creating resilient, energy-efficient, and sustainable urban spaces. Architects and designers have a responsibility to shape cities that harmonise with the environment rather than exploit it. By embracing materials such as timber, stone, rammed earth, and terracotta, we can forge a new paradigm of urban development that respects both nature and human needs. It is necessary to continue to explore and implement innovative material strategies that redefine urban architecture for a greener tomorrow.

Importance of Containing and Controlling Fire - A Critical Examination

Fires have been a part of human history, serving as both a tool for progress and a formidable foe. While fire has driven technological advancements and supported human sustenance, its uncontrolled manifestation can lead to catastrophic consequences. In the modern era, with densely populated cities, high-rise buildings, industrial complexes, and sprawling urban infrastructure, the need to contain and control fire has never been more pressing. Failure to implement effective fire containment measures can escalate into disasters that wreak havoc on lives, property, and the environment.

THE NATURE OF FIRE: FRIEND AND FOE

Fire, at its core, is a chemical reaction. It requires three elements: heat, fuel, and

oxygen. This simplicity belies its potential for destruction. Left unchecked, a small ignition can rapidly develop into an inferno, obliterating entire structures and landscapes. The destructive power of fire is amplified in environments where flammable materials, improper safety measures, and human negligence coexist.

Fire, though a valuable tool, remains one of the most destructive forces when uncontrolled. The importance of containing and controlling fire is particularly pronounced in India, given the country’s dense urbanisation and industrial growth. Are we ready to face the challenges of fire emergencies with adequate preparedness? Addressing this requires a collective effort from governments, industries, and citizens

to prioritise fire safety and ensure compliance with robust measures. The time to act is now.

THE COST OF UNCONTROLLED FIRES

Loss of Human Life: Fires claim thousands of lives annually worldwide. In India, incidents such as the 2017 Kamala Mills fire in Mumbai and the 2020 fire at a COVID-19 hospital in Ahmedabad resulted in significant fatalities, highlighting gaps in safety compliance.

Economic Damage: Fires result in significant economic losses. The 2019 fire at the Delhi Anaj Mandi factory caused financial devastation alongside the loss of lives. Industrial fires in chemical and textile plants often lead

Fires claim thousands of lives annually worldwide

to the destruction of inventory and infrastructure, impacting livelihoods and production cycles.

Environmental Impact: Fires in factories, chemical plants, or oil storage facilities release toxic pollutants into the environment. The 2019 ONGC gas plant fire in Navi Mumbai is an example of how industrial fires can result in environmental degradation and health hazards.

Psychological and Social Toll: Survivors of fire incidents often face long-term trauma, displacement, and a loss of community cohesion. The displacement of families in urban slum fires, such as the 2018 Malad slum fire in Mumbai, underscores the human cost of inadequate fire safety.

FIRE CONTAINMENT AND CONTROL

Prevention of Escalation: The primary goal of fire containment is to stop its spread. Buildings and industrial structures must incorporate advanced fire suppression systems, such as sprinklers, fire doors, and smoke exhaust systems, to limit the fire’s reach. Early containment minimises damage and ensures the safety of occupants.

Protecting Vulnerable Populations:

Hospitals, schools, and high-rise residential buildings house individuals who may struggle to evacuate during a fire. In India, incidents like the fire at AMRI Hospital in Kolkata in 2011, which killed over 90 people, highlight the importance of robust containment measures to protect vulnerable populations.

Safeguarding Industrial Operations:

Fires in industrial facilities, such as chemical plants, factories, and warehouses, can have far-reaching consequences beyond physical damage. The 2021 fire at the Serum Institute of India’s Pune facility, where COVID-19 vaccines were being produced, underscores the critical need for stringent fire control measures in industrial settings.

Mitigating Urban Fire Risks: In densely populated Indian cities, where high-rise buildings and congested neighbourhoods are common, fire containment systems are essential to prevent rapid fire spread. The 2019 Delhi Anaj Mandi fire revealed how a lack of escape routes and proper fire control mechanisms can lead to significant loss of life.

Fire Safety

CHALLENGES TO FIRE CONTROL IN INDIA

Despite advancements in fire safety technology, several challenges persist in the Indian context:

Urbanization: Rapid urban growth has led to overcrowded cities with poorly planned infrastructure, increasing fire risks in high-rise buildings and informal settlements

Aging Infrastructure: Many older structures lack modern fire safety systems, making them more vulnerable to incidents.

Lack of Fire Resistance Material Testing Laboratories: India faces a significant gap in the availability of fire resistance material testing laboratories. Without access to reliable testing facilities, many construction materials are used without proper certification for fire safety, increasing the vulnerability of structures to fire hazards.

Lack of Awareness: Many individuals remain unaware of fire hazards and basic safety measures, leading to preventable accidents. Regular fire drills and public awareness campaigns are often absent in residential areas.

Regulatory Compliance: Enforcement of fire safety regulations is inconsistent. High-profile cases have revealed lapses in adherence to safety norms and insufficient inspections.

ARE WE READY FOR EMERGENCY PREPAREDNESS?

Current State of Emergency

Preparedness in India: Emergency preparedness in India varies across regions and sectors. While metropolitan cities like Mumbai and Delhi have fire departments equipped with modern tools, smaller cities and rural areas often lack resources. The response to fires in urban slums and unregulated industrial zones remains inadequate due to systemic challenges.

Key Elements of Preparedness

1. Fire Prevention: Stringent enforcement of fire safety codes,

Fire Safety

1. particularly in commercial and industrial buildings, is critical. Retrofitting older buildings with fire safety measures is a pressing need.

2. Early Detection: Advanced alarm systems, heat sensors, and smoke detectors must be mandatory in all buildings and industrial facilities.

3. Rapid Response: Fire departments must be equipped with modern tools, such as aerial ladders and fireresistant suits, to tackle high-rise and industrial fires effectively.

4. Community Involvement: Empowering communities through training and resources can enhance localised fire response efforts. Fire drills in schools, residential complexes, and industrial zones should be routine.

5. Policy and Regulation: Authorities must ensure stricter adherence to fire safety regulations. Noncompliance, as seen in many high-profile cases, must result in substantial penalties.

LESSONS LEARNED IN INDIA

The Kamala Mills Fire (2017)

The fire at Kamala Mills in Mumbai, which killed 14 people, highlighted

the dangers of illegal construction, overcrowded spaces, and noncompliance with fire safety norms. The tragedy underscored the need for stricter regulatory enforcement and routine inspections.

AMRI Hospital Fire (2011)

The AMRI Hospital fire in Kolkata revealed the consequences of poor emergency preparedness in healthcare facilities. Blocked exits and a lack of compartmentalisation, fire stopping, and passive fire protection, functional Fire alarms contributed to the high death toll. The incident emphasised the importance of stringent safety audits in hospitals.

Delhi’s Anaj Mandi Fire (2019)

This industrial fire exposed the risks associated with unregulated factories operating in residential areas. Lack of fire exits and overcrowding exacerbated the tragedy, highlighting the urgent need for zoning regulations and fire safety compliance

MOVING FORWARD: BUILDING A FIRE-RESILIENT INDIA

Fire-Retardant Materials: Fireretardant materials, tested by reputed laboratories, are designed to withstand high temperatures and delay fire spread,

buying critical time for evacuation and firefighting efforts. These materials are integral to construction, especially in high-risk environments such as industrial plants and high-rise buildings. Ensuring rigorous testing and certification of these materials is vital for their effectiveness.

IoT-Based Fire System Monitoring: IoTenabled fire monitoring systems provide real-time data on the operation and status of fire safety equipment such as sprinklers, smoke detectors, and alarms. These systems detect malfunctions, trigger immediate alerts, and enable predictive maintenance, reducing the likelihood of equipment failure during emergencies. This continuous monitoring ensures a high level of preparedness.

AI-Powered Fire Detection Systems:

Artificial intelligence can significantly enhance fire safety by identifying heat sources, smoke, or unusual patterns indicative of fire. Advanced AI systems are capable of analysing video feeds and sensor data in real time, allowing for early detection and minimising false alarms. AI also facilitates smart decision-making by integrating data from multiple sources to guide firefighting efforts efficiently.

Automated Suppression Systems: Automated fire suppression systems, such as gas or foam-based systems, are particularly effective in industrial and data-sensitive environments. These systems activate instantly upon detecting fire or heat, ensuring immediate containment and reducing the need for manual intervention.

Smart Building Integration: Modern buildings equipped with smart systems can integrate fire safety technologies with centralised control systems, allowing operators to monitor and manage fire risks across multiple locations from a single platform. This integration enables faster decision-making and coordinated responses during emergencies.

Capacity Building: Training programs for firefighters, safety officers, and

community volunteers can bolster emergency preparedness.

Strengthening Regulations: Fire safety codes must be updated regularly, and their enforcement should be nonnegotiable.

Public Engagement: Educating citizens about fire risks and response protocols is crucial for fostering a culture of safety.

Investment in Infrastructure: Increased funding for modern firefighting equipment, personnel training, and infrastructure upgrades is essential for improving response capabilities.

SAFE LIVING IS A FUNDAMENTAL RIGHT

Fire, though a valuable tool, remains one of the most destructive forces when uncontrolled. The importance of containing and controlling fire is particularly pronounced in India, given the country’s dense urbanisation and industrial growth. Effective fire safety measures are not just about compliance; they are about saving lives, protecting

property, and maintaining economic stability.

To achieve a fire-resilient society, a multi-faceted approach is essential. This involves leveraging advanced technologies, such as AI-powered fire detection and IoT-based monitoring systems, ensuring the use of rigorously tested fire-retardant materials, and enforcing strict fire safety regulations. Moreover, educating communities and empowering individuals with fire safety knowledge can create a culture of preparedness that extends beyond regulatory frameworks.

The cost of ignoring fire safety is far greater than the investment required to implement robust systems. Every stakeholder—governments, industries, and citizens—must collaborate to prioritise fire safety as a national concern. Only through collective efforts can India mitigate the devastating impact of fire incidents and pave the way for a safer, more secure future. The time for action is not tomorrow; it is now.

Importance of Materials Selection for Fire Safe Building and Façade

Safety is not a priority; it is a duty we owe to ourselves and others, particularly when it concerns fire safety measures. To a certain extent, fire control and resident escape can’t be accomplished if a building’s height is over 15 meters, and evacuation procedures are more crucial within a reasonable time frame. The same

is true for places with large footfalls or mobility, such as hospitals, old age homes, universities, metro trains, stations, warehouses, auditoriums, etc. We constantly have issues with the way our buildings are designed to withstand fire, especially the façade system, which poses a serious risk when a fire breaks out.

In any modern building, evacuation of the building occupants is a main consideration in the design of any building. Today, a general fire safety concept used in designing a building considers points like how fast can occupants egress; How fast the fire brigade can extinguish a fire; and how the fire spread could be avoided in surrounding buildings.

For high rise building perfect plan should moves people from the directly affected territories to closest safest location because hight of the building high number of occupants.

STRUCTURAL SAFETY AND SAFETY OF PEOPLE’S LIVES

The façade contains the highest risk we have seen so far in terms of the safety of the building. The majority of the fatal fires occur in façade fires. There are two basic timelines on which fire phenomena can be divided:

• Start of the fire to the first 5 minutes

• Beyond the first 5 minutes.

The first 5 minutes define how the developed fire will be affecting your

building. It can be a considerable risk factor for fire propagation in the external building envelope and rear ventilation walls, with potential flashover between floors and possible entry into the building interior.

Propagation of Fire

Two physical properties of fire will increase the propagation of flames from one floor to the floor above on the exterior of the building:

• Convection: Products of combustion (heat, hot gases and fire) that are buoyant and will travel upward.

• The Coanda Effect: Will bring the steam of hot gases (and flame) back against building surfaces.

EN 13501-1 matters most as far as building materials selection is concerned.

To offer the highest possible fire safety protection, all materials that become part of an external façade must achieve classA2-s1, d0, or class A1.

Fire resistance vision panel glass combines visibility with effective flame and smoke spread prevention.

A1 class non-combustible class do not contribute to fire, do not contribute to burning or smoke development characteristics under the fire, do not emit any energy, and do not contain almost any organic materials inside them. Where organic substance contains a maximum of 1% volume and weight inside the item, we may consider it an A1 class product.

A2 class materials are limited combustible or hardly combustible.

The façade is required to be hardly flammable which is a minimum C class when it is not a high-rise building. In the case of high-rise buildings that need stronger fire safety, then all façades must be made with at least A2 class or hardly combustible class of product.

Importantly, low-rise buildings with conventional façade systems must be insulated with harder materials of the first 1.5-meter height of the building. In the first 1.5 meters, where car parking and garbage bins are located, there is a high chance of fire as both garbage bins and cars can catch fire very easily. Hence the first 1.5-meter height of a building façade required additional

Class A1 Products in this class do not contribute to burning, fire development, or smoke development in any phase of the fire.

Class A2 Do not contribute to fire effec�vely under fully developed fire circumstances.

Class B Material that is considered combus�ble but has a limited contribu�on to fire.

Class C Products in this class have a limited contribu�on to fire, meaning they will contribute to fire less than Class D or E materials.

Fire Safety

non-combustible materials. Then there are some openings from where fire can easily enter inside the building façade; therefore, openings like windows should be insulated top and bottom with A1 class materials.

Open joint or ventilated curtain walling systems used in buildings must contain façade and insulation materials of minimum limited combustible (Class A2) class.

What happens to the façade in a developed fire situation in case the correct materials are not selected for facades

Any sandwiched panel that contains polyeutherin (Class C materials –Hardly flammable) starts to emit smoke in the first few seconds even before fire touches it. This smoke is polyisocinide smoke. It generates cyanide acetate /ureic acetate. Both are very poisonous to humans and animals. It is important to know that a one-meter cube of such materials generates a 10000-meter cube of such poisonous gases within a minute. The heat is critical for structural collapse however smog is deadly for the people living inside the building.

All uncovered and unpainted metals, homogenous mineral wools without organic binders or interphase layers, mineral-based products such as calcium silicate, gypsum, cement-based products, bricks, etc. where the organic substance content is less than 1% by volume and weight.

Organically coated or painted mineral wools, with organic binders or interphase layers, organic addi�ve containing cement-based products, gypsum boards with organic layers, etc.

FIRE SAFE FAÇADE

CASE -1

Building A (Insulated Façade)– One side of the tower completely burned. But the fire did not spread to the other sides. Because the rest of the sides were insulated by mineral wool & concrete. The material here that got completely burnt down was the Aluminium Composite Panel (ACP). The total fire height was 140 meters and the burning time was 3.5 minutes only. Hence average burning rate was 40 meters per minute or 2 meters per 3 seconds. So even before the fire brigade could reach, the fire was over.

CASE -2

Building B (Non-Insulated Façade) –Building height 67.3 meters. The whole building was burnt down and 72 people died in this fire. It took only 12 minutes for the fire to spread all over the building. Due to a large fridge fire inside the building, a few UPVC windows caught fire and melted down. Then Aluminium Composite Panels (ACP) were ignited. It was impossible to escape from the building due to the dense smoke that filled the entire lobby.

Façade and Fenestrations: A Harmonious Blend of Function and Aesthetics

At the outset, windows play a crucial role in any building by providing natural light and ventilation. Together with the building envelope, they form the façade, which defines the structure’s aesthetic and functional character. The right choice of materials and products enhances visual appeal while also improving performance. By integrating advanced technology and innovative materials, façades can achieve superior acoustic insulation and thermal efficiency, creating more comfortable and sustainable built environments

The relationship between windows and a building’s façade is a fundamental aspect of architectural design, influencing both aesthetics and functionality. Windows serve as the interface between interior and exterior spaces, shaping the visual appeal of a structure while also playing a crucial role in natural lighting, ventilation, and energy efficiency. Façades, on the other hand, define the building’s identity, integrating materials, textures, and window placements to create a cohesive and striking appearance.

This article explores the intricate connection between windows and façades, examining how their design impacts the overall performance, sustainability, and visual character of buildings. From traditional masonry façades with symmetrically arranged openings to modern glass curtain walls that maximise transparency, the evolution of architectural styles has continuously redefined their interaction. Understanding this relationship is key to creating structures that are both visually compelling and functionally efficient.

Brick Weave House: Memory and Façade

In the Brick Weave House, the client’s childhood memory has been preserved through the façade.

Cubbon Peth historically housed Bangalore’s oldest handloom silk weavers’ colony. In the post-industrial era, the art of hand-crafted silk weaving has gradually disappeared over time. The client comes from a family of weavers and has fond childhood memories of traditional weaving systems. To preserve this heritage, traditional weaving was translated into brick weaving, leading to the creation of the Brick Weave House (Figure 1a).

The project is one of many row houses in the weavers’ colony, sharing or abutting walls. The challenge of light and ventilation is addressed only through the street-facing façade or the sky. Reflecting its context metaphorically, the “Brick Screens” are “woven” using MS rods along the fenestration of the façade. The combination of the solid brick wall and the Brick Weave screen blends harmoniously with the historic surroundings of the old town (Figure 1b).

FAÇADE DESIGN

The innovative design of the Brick Weave Screens is achieved by rotating bricks along their axis at angles of 45, 90, and 135 degrees, preventing pigeons, birds, and rain from entering while allowing sufficient light and

ventilation, along with privacy (Figures 1c & 1d). The brick weave animates the common staircase and duplex interior with dappled sunlight, offering a subtle visual connection to the street from the inside while appearing mostly opaque from the outside. The brick weave screens generate polygonal voids, casting hexagonal patterns of light during the day and projecting the same patterns outward at night. This effect transforms the façade into a lantern, illuminating the dark alley after sunset (Figure 1e).

A Home by the Park: Context and Façade

“A Home by the Park” is a beautiful house with an infinite visual connection to the park (the neighbourhood park outside the plot).

The nature-loving clients asked us to design a home that resonates with nature and expresses it throughout. We took advantage of the public park in front of the site to extend nature beyond their plot. By incorporating the public park into our design, we created a home that feels as though it is nestled within nature, both physically and visually. The inhabitants are physically connected to nature through a series of themed gardens – the Front Serene Garden, the Central Rain Court, and the Private Back Garden – while the public park remains seamlessly connected visually.

The front garden welcomes guests with a sense of tranquillity and peacefulness.

Innovative façade

To strengthen the connection between the park and the garden, it has been raised to a level where they form one vast visual green scape. Though these spaces are separate, they remain visually connected.

FAÇADE

The window façade was uniquely designed with a system of wooden shutters acting as curtain glazing. The detail involved positioning the glass in front of the shutters using adhesives.

House of Greens: Vegetation and Façade

Bangalore is well known for its gardens and is referred to as the “City of Gardens.”

In an urban scenario, high-density urban homes are common; however, this project was fortunate to be surrounded by greenery. The quest to utilise the natural greens in the surroundings was key to creating the House of Greens—a home that connects to nature both physically and visually.

House of Greens is a unique project catering to prestigious clients with a deep appreciation for nature and sustainability. The clients are dog lovers, green

enthusiasts, down-to-earth doctors, and peace lovers, committed to a sustainable lifestyle. The design brief for House of

Greens reflects their values and personality, focusing on creating a sustainable green home with an abundance of greenery.

and leads to the master bedroom with a private balcony in direct contact with nature, every aspect enhances this connection.

The design has been carefully curated, focusing on natural elements such as laterite stone cladding, natural granite, and wooden doors and windows (Figures 3b & 3c). The house is well-

ventilated, with plenty of natural light and airflow, creating a positive and pleasant atmosphere.

Additionally, a variety of indoor plants, a rooftop garden, and a lush backyard bring the beauty of nature into the living spaces, providing a tranquil and peaceful environment for the residents (Figures 3d & 3e).

Bollywood Twister: Unfolding Emotions with Indian Cinema

To design a new island for the Film City Tower in ‘Mahim Bay’, across the BandraWorli Sea Link in Mumbai. The site island is located approximately 100 metres off the BWSL promenade in the Mahim Bay waters, adjoining the Western Express Highway. It is bounded by the Bandra Reclamation area to the north and west, and Mahim and Worli to the far east and south, respectively (Figure 4a).

RASA

The Rasa method of performance is one of the fundamental features

that differentiate Indian cinema from that of the Western world. In the Rasa method, empathetic emotions are conveyed by the performer and thus felt by the audience, in contrast to the Western Stanislavski method, where the actor must become ‘a living, breathing embodiment of a character’ rather than simply conveying emotion. A Rasa denotes an essential state of mind and is the dominant emotional theme of a work of art or the primary feeling evoked in the person who views, reads, or hears such a work.

NAVARASA

Rasa has been an important influence on Indian cinema. The design by 4site Architects attempts to explore ‘the Navarasa’ - the emotions expressed through facial expressions, hand gestures, and body movements. The proposed tower’s expression responds to all nine Rasas through its colour, texture, and functions (Figure 4b):

• Shoka – sadness

• Veera – heroism

• Bhayanaka – horror

• Bhibhasta – disgust

• Adbhuta – wonder

• Kroda – anger

• Hasya – joy

• Karuna – sympathy

• Prema – love

MUMBAI STREET

A variety of public functions within the tower would greet visitors with panoramic views of the city. The ramp that wraps around the tower reinterprets conventional design by incorporating Mumbai’s urban landscape into its structure, encouraging social interaction and distributing communal spaces throughout the tower—an aspect often absent as buildings rise in height. This twisting ramp, themed as ‘Mumbai Streets’, connects all the Navarasas at various levels, responding to each respective emotion. Panoramic views

of Mumbai can be experienced along these vertical streets at different heights, enhancing the experiential quality of the design. (Figure 4c).

Shiva Temple Complex: Divine and Order

India is a land of diverse cultural and religious hubs, and temples have always been sites of cultural importance. The state of Karnataka is well known for temples at Hampi, Beluru, etc., which are architectural marvels. Inheriting these values, proposing a contemporary temple complex on this site, which abuts the Hubballi–Bengaluru highway, was a challenge.

This temple complex is dedicated to Lord Shiva, where the main temple and the smaller shrines dedicated to other deities are built respecting the Dravidian temple architecture by Sthapati Swaminathan and his team.

The requirement from the clients was to propose a temple complex with facilities

such as a guest house, kitchen, dining hall, priest accommodation, and other Dravidian temple elements incorporated accordingly, such as the Gaushala, Kalyani, etc.

The temple journey is articulated in four parts: The Arambha Patha, the Parivarthana Patha, the Adhyatmika Gola, and the Avalokana Patha.

As one approaches the temple complex from the highway, they are guided to the “Bazaar Street,” where they initiate their path to approach the divine— “The Arambha Patha.” The Arambha Patha encompasses some shops and refreshments, and also, the queue of people is directed towards the next path slowly here (Figure 5a).

Following this is the ‘Parivarthana Patha,’ where one enjoys their walk towards the main temple complex through a series of covered colonnades and pavilions. These pavilions engage people with the stories of the Lord embedded in them, also giving sneak peeks of the Rajagopura. The Rajagopura unveils itself as a magnificent structure as one enters the East Pavilion and glances towards the main temple complex. This path conditions one’s mind to connect with their spirit.

As one steps further, they will approach the ‘Adhyatmika Gola’—the spiritual sphere where the temple is located.

As one visits the main and smaller temples, they are guided towards the Ratha Beedi, from where they can approach the ancillary buildings, the guest house, and the dining hall.

The ‘Avalokana Patha’ is the path that allows one to contemplate their journey so far. Here, again, we get to witness the North Pavilion, where one can approach the Gaushala. As one steps

forward towards the colonnades and pavilions, they get to witness the cultural events held at the amphitheatre. As one proceeds further, they approach the Kalyani—the sacred pond. Moving on, they reach the exit.

THE PROCESS FOR ANCILLARY WINDOW

The windows of the ancillary buildings were required to match the “temple architecture” (Figure 5b & 5c). The challenge was to mask the modern window systems (uPVC windows). To achieve this, we initially explored WPC boards with floral patterns (Figure 5d). However, the white-coloured WPC did not complement the material theme.

The client’s fabrication team suggested CNC-cut panels (Figure 5e) with powder coating, but the patterns created sharp edges that could pose a risk to occupants. Subsequently, a simple MS grill pattern was proposed as a solution (Figure 5f). The temple Stapati recommended a stone jali with floral patterns (Figure 5g). While this option appeared aesthetically pleasing, it proved to be expensive and time-consuming for the project.

Eventually, we proposed a simple diamond-shaped stone jali (Figure 5h) that provided a similar aesthetic value by effectively concealing the modern window systems. The stone also allowed for optimal daylight penetration into the interiors while acting as a security grille.

What is your take on sustainable façade and fenestration designs?

Nishanth H.H (NHH): Sustainable façade and fenestration design is fundamental to energy-efficient and environmentally responsible architecture. Thoughtful planning of window and glazing locations can optimise daylighting, ventilation, and thermal comfort.

For example, north-facing windows (in the Northern Hemisphere) allow consistent natural light without excessive heat gain, while south-facing openings benefit from shading devices such as overhangs, fins, or louvres to prevent overheating. Eastand west-facing windows, which are prone to glare and heat gain, should be minimised or effectively shaded.

Building orientation further enhances sustainability by aligning the structure with the sun’s path and prevailing wind patterns. Orienting the longest façade to face north-south reduces solar heat gain and facilitates passive cooling through cross-ventilation.

Choosing sustainable façade materials— such as recycled metal, photovoltaic panels, green walls, corten steel, and high-performance glazing—minimises environmental impact while improving insulation and durability.

Smart façades take sustainability to the next level by integrating advanced technologies like dynamic glazing, photovoltaic panels, and automated shading systems that respond to environmental conditions. These features adapt to changes in temperature and sunlight, ensuring optimal energy efficiency and occupant comfort.

other partners to make sure each project is a success.

Together, these strategies enable buildings to achieve reduced operational energy consumption, enhanced user comfort, and a smaller carbon footprint while exemplifying modern, sustainable design principles.

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

NHH: Our design process for façades and fenestrations revolves around creating a unique identity for each project while prioritising sustainability, user experience, and attention to detail.

We begin by immersing ourselves in the context and purpose of the project— analysing the site’s climate, cultural influences, and the building’s function. This informs the development of a façade that reflects the project’s character, whether through innovative use of materials, shapes, or patterns, creating a distinct architectural identity.

Sustainability is a core principle throughout the process. We select highperformance, eco-friendly materials, such as energy-efficient glazing, recycled metals, and renewable resources, to minimise the building’s environmental impact. We also optimise the placement

of windows to maximise daylight, reduce energy consumption, and ensure thermal comfort.

Enhancing the user experience is central to our design approach. We aim to create façades that allow for ample natural light and views while minimising glare and maintaining a comfortable indoor climate. The strategic use of shading devices, operable windows, and thoughtful detailing ensures that occupants enjoy a pleasant, functional space.

Finally, we are detail-oriented, ensuring that every design decision - whether structural, material, or aesthetic - is carefully considered. Our goal is to create façades that not only function sustainably but also contribute to the project’s identity, making it memorable and impactful for both users and the community.

Please talk about some of the most preferred façade materials.

NHH: In our projects, we favour materials that not only offer high performance but also enhance the building’s visual and environmental integrity. Highperformance glass is a cornerstone of our façade designs. It allows for optimal daylighting while minimising energy loss and heat gain, creating a comfortable interior climate. Additionally, the transparency of the glass enhances the building’s connection to its surroundings, contributing to both aesthetic appeal and occupant well-being.

Aluminium is another material we often choose for its versatility and durability. It is lightweight corrosion-resistant, and easy to maintain, making it ideal for intricate designs and large-scale installations. Its recyclability adds to its sustainability, ensuring the facade remains eco-friendly.

Zinc is valued for its timeless, natural appearance. As it weathers, zinc develops a unique patina, giving the façade a dynamic and evolving look. It is lowmaintenance and extremely durable, making it perfect for projects that require both aesthetics and longevity.

Terrazzo panels bring texture and a sense of luxury to façades. Made from a combination of marble, quartz, or other aggregates set in concrete, terrazzo offers both sustainability and design flexibility. It is durable, low-maintenance, and can be customised in a wide range of colours and finishes, contributing to a unique and elegant façade that also offers thermal mass benefits.

Could you please brief me on the latest trends in façade and fenestration designs, materials, and technologies?

NHH: The latest trends in façade and fenestration designs reflect a growing focus on sustainability, innovation, and enhanced user experience. Among the most exciting developments are dynamic façades, smart glass, IoT in façades, and photovoltaic façades, all of which contribute to energy efficiency and environmental responsiveness.

Dynamic façades are revolutionising building design by allowing façades to adapt to changing environmental conditions.

These façades feature adjustable elements such as shading devices, louvers, and operable panels that respond to sunlight, temperature, and weather, optimising energy use and improving indoor comfort. By reducing solar heat gain and glare, dynamic façades help minimise the need for artificial lighting and mechanical cooling, thus lowering a building’s energy consumption.

Smart glass, also known as electrochromic glass, is another major trend. This technology enables glass to change its opacity in response to electrical signals. Smart glass reduces heat buildup, glare, and the need for blinds, allowing for greater control over the indoor environment while maintaining access to natural light and views.

The integration of IoT in façades enables real-time monitoring and control of building systems. Sensors embedded in façades track environmental variables like temperature, humidity, and light, allowing automatic adjustments to heating, cooling, and ventilation systems. This intelligent approach improves energy efficiency and ensures optimal comfort.

Please brief on the things to consider while designing the most sustainable façades and fenestrations, and their designs.

NHH: When designing sustainable façades and fenestrations, it’s crucial to focus on creating energy-efficient buildings that minimise their environmental impact while improving occupant comfort. Several factors play a significant role in achieving these goals, and considering them will ensure the façade and fenestration designs are not only visually appealing but also responsible and functional.

Building orientation is one of the key elements to consider. The positioning of a building can have a major impact on its energy consumption. By strategically placing façades and fenestrations, you can optimise natural light penetration, which reduces the need for artificial lighting. Moreover, proper orientation helps regulate solar heat gain, leading to better thermal performance and reducing the need for air conditioning and other cooling systems.

Choosing the right materials is equally important. Sustainable material selection is essential for ensuring durability and energy efficiency in the façade. Using materials such as high-performance glass, aluminum, or locally sourced and recycled materials helps minimise the environmental footprint. Materials with high insulation properties, such as thermally efficient glazing, are particularly

Zonasha Business Park, Bengaluru

beneficial in preventing heat loss during colder months or heat gain in warmer climates, enhancing the building’s overall energy efficiency.

Energy efficiency should be a priority when it comes to glazing systems. Incorporating energy-efficient technologies like double or triple glazing, low-emissivity (Low-E) coatings, and thermally broken frames can significantly improve the building’s thermal performance. In addition, advanced technologies such as BuildingIntegrated Photovoltaics (BIPV) can transform façades into power-generating surfaces, which not only provide renewable energy but also contribute to the building’s energy autonomy.

Smart fenestrations, which include intelligent systems like electrochromic glass and dynamic shading devices, are another essential aspect. These systems automatically adjust to changing environmental conditions, controlling solar heat gain, glare, and light levels. Such technology improves user comfort while also reducing energy consumption by adjusting to real-time needs.

Lastly, maintaining sustainability goes beyond design and materials. The maintenance and durability of the façade should also be taken into account. Sustainable façades should be easy to

maintain and designed to last for many years, with materials and systems that can withstand environmental stress and require minimal upkeep. This approach helps ensure the long-term efficiency of the building while reducing maintenance costs over time.

By focusing on these factors, architects can design façades and fenestrations that are sustainable, energy-efficient, and contribute to a building’s overall environmental performance.

What are the design tools used in designing effective and efficient façades for buildings?

NHH: To design façades that are both effective and efficient, architects today rely on a combination of advanced tools that focus on performance, sustainability, and user experience. Key technologies such as Building Information Modelling

(BIM), Artificial Intelligence (AI), Virtual Reality (VR), and computational design have significantly reshaped the façade design process, making it more datadriven, precise, and adaptable.

BIM is instrumental in creating comprehensive 3D models that integrate all aspects of a building’s façade. By providing a platform for architects, engineers, and contractors to collaborate, BIM enables design decisions to be based on accurate, up-to-date data. This tool also allows for simulations that optimise factors such as energy use, daylighting, thermal efficiency, and material selection, helping to refine the façade’s performance before physical work begins.

The integration of AI brings another layer of optimisation by analysing large datasets, such as weather patterns, sunlight, and air circulation. AI-driven systems can generate façade designs that improve energy efficiency and enhance comfort. Furthermore, AI tools can predict the long-term durability and maintenance needs of façades, ensuring that they remain effective and sustainable throughout their lifespan.

VR enhances the design process by allowing both designers and clients to interact with 3D representations of the façade in an immersive environment. This provides a better understanding of how the design will look in real life, making it easier to identify issues and refine designs early on.

“The future of façade technologies, designs, and materials over the next two decades will be marked by a harmonious integration of innovation, sustainability, and advanced design principles”

Aster Hospital, Kasaragod

Face to Face

Lastly, computational design tools allow for the exploration of complex geometries, using algorithms to create optimised façade solutions that balance aesthetic beauty with high performance, minimising material waste and maximising sustainability. Together, these tools empower architects to create façades that are not only visually appealing but also efficient, durable, and environmentally responsible.

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

NHH: The future of façade technologies, designs, and materials over the next two decades will be marked by a harmonious integration of innovation, sustainability, and advanced design principles. As the architectural industry shifts towards environmental stewardship and occupant well-being, façades will evolve from mere protective layers into dynamic, high-performance

systems that enhance energy efficiency, aesthetic appeal, and environmental sustainability.

Smart façades will play a pivotal role in this transformation. By incorporating advanced materials like electrochromic glass, these façades will adjust their transparency in response to changes in sunlight and temperature. This ability to control heat gain and light Smart façades will play a pivotal role in this transformation. By incorporating advanced materials like electrochromic glass, these façades will adjust their transparency in response to changes in sunlight and temperature. This ability to control heat gain and light levels will reduce reliance on artificial lighting and cooling, improving energy efficiency while still maintaining natural light and expansive views. Additionally, dynamic shading systems will allow façades to respond automatically to the sun’s movement, minimising solar heat gain and preventing excessive glare, which in turn reduces energy costs.

Another key trend will be the development of energy-generating façades. With the integration of buildingintegrated photovoltaics (BIPV), façades will transform into active energy producers. Solar panels embedded within the building envelope will convert sunlight into electricity, powering the building or contributing excess energy to the grid. Advances in solar technology and design integration will make these systems more efficient and visually appealing, turning façades into essential components of a building’s renewable energy strategy.

As environmental concerns intensify, biophilic and living façades will become more common. Plant-covered walls, or green façades, will not only improve the building’s aesthetic value but also contribute to air purification, thermal insulation, and the reduction of the urban heat island effect. Hydroponic and aquaponic systems could also be incorporated, allowing for vertical gardening that contributes to sustainable food production.

Furthermore, AI and automation will revolutionise façade design and performance. Intelligent systems will continuously monitor environmental conditions, adjusting the building’s energy use and enhancing occupant comfort. Automated manufacturing and installation processes will streamline façade production, making highperformance and sustainable façades more accessible and cost-effective.

Looking ahead, the next 20 years will bring significant evolution to façades, transforming them into multi-functional, sustainable, and responsive systems. These changes will play a crucial role in enhancing a building’s energy efficiency, shaping its aesthetic identity, and reducing its environmental impact. As a result, the way buildings interact with their surroundings will be redefined, paving the way for more intelligent and eco-friendly architecture in the future.

IMPACT OF FAÇADE MATERIALS ON ENERGY CONSUMPTION, THERMAL PERFORMANCE, DURABILITY, AND MAINTENANCE

Ar. Sumit Dhawan - Founder and Principal Architect, Cityspace’ 82 Architects, observes that a highperformance glass can reduce energy consumption by regulating indoor temperatures, while aluminium composite panels (ACPs) provide lightweight durability and weather resistance. Steel offers structural strength but needs treatments to resist corrosion, especially in urban environments. Materials like stone or concrete cladding provide excellent thermal mass but can be resource-intensive. He advocates for a blend of materials tailored to the project’s location, environmental factors, and aesthetic requirements.

Ar. Gaurav Sanghavi, Co-Founder & Principal Architect, Pentaspace Design Studio, notes that a building’s façade serves as its protective skin, interacting with environmental factors like heat absorption and temperature fluctuations. He stresses that careful material selection enhances energy efficiency. Double-glazed units (DGUs) mitigate external noise and regulate heat gain but require strategic placement—being most effective on south, east, and west-facing façades. Integrating a service core or more opaque elements on the south façade reduces heat absorption. Beyond materials, architectural planning is crucial, with perforated panels providing self-shading, double-skin façades offering insulation, and jali screens integrated with glazing to diffuse heat.

Ar. Jamshed Banaji and Ar. Nirmala Banaji, Principal Architects, Banaji and Associates, emphasise that façade materials significantly impact thermal performance and energy efficiency. Glass allows natural light but must be used with double or triple glazing to minimise heat transfer. Aluminium and steel offer durability but contribute to thermal conductivity unless properly

insulated. Wood provides natural insulation and aesthetic appeal but requires maintenance, particularly in humid climates. They assert that material selection should balance thermal performance, lifecycle durability, and maintenance needs with the building’s function and aesthetics.

Ar. Kanupriya Upadhyaya, Senior Architect and Project Manager, INI Design Studio, notes that façade materials are often overlooked but play a vital role in energy efficiency. These materials act as the first line of defence against external weather conditions, impacting energy consumption and urban climate. Double or triple-glazed glass insulates well but requires shading elements like louvres or overhangs to prevent overheating. Aluminium is durable but needs insulation to reduce heat transfer, while steel, known for its strength, requires thermal management. Wood offers warmth and insulation but demands weatherproofing treatments. She asserts that façades should be seen as dynamic components, integrating smart insulation, coatings, and shading systems to enhance energy efficiency and indoor comfort.

Maintenance and durability are also key factors. Glass requires frequent cleaning,

though laminated or tempered variants offer higher impact resistance. Aluminium accumulates dirt and needs periodic cleaning, while steel requires protective coatings to prevent rust. Wood, though naturally beautiful, demands sealing and painting to ensure longevity. Upadhyaya concludes that striking a balance between aesthetics, performance, and maintenance is crucial, aligning material choices with climate conditions and sustainability goals.

Ar. Sandeep Rajendran, Director –Design & Projects, Aedium Design, stresses that façade material selection significantly impacts energy consumption and thermal performance. Each material has its advantages and challenges. Glass enhances natural light but can lead to heat gain, increasing cooling demands. Innovations like low-emissivity coatings and double-glazed units improve performance but at a higher cost. Aluminium is lightweight, durable, and low-maintenance but energy-intensive to produce; recycled aluminium and thermally broken systems help mitigate this impact. Steel offers structural strength but requires protective coatings against corrosion, while engineered wood products like cross-laminated timber (CLT) provide sustainable alternatives.

Durability and maintenance considerations are essential. While aluminium and steel are low-maintenance, wood requires regular care. Glass façades, though visually appealing, can be expensive to clean and repair. Balancing these factors ensures sustainability and practicality in façade design.

Ar. Vishnu Mohan, Associate Architect, Architecture Dialogue, highlights that in India’s diverse climates, material selection requires strategic planning. Glass, while low-maintenance, needs

careful application in hot regions. For a 180m residential tower in Hyderabad, high-performance glazing with Low-E coatings was used on the west and south façades, reducing solar gain by 27%. In Visakhapatnam, a dry-clad local stone panel was chosen for a pharmaceutical corporate office to reduce heat absorption and reflect the coastal city’s rugged aesthetic. Aluminium frames were thermally broken to prevent heat bridging, while steel was avoided due to maintenance concerns in saline air. Each choice prioritised longevity and climatespecific performance over trends.

Dr. Manvendra Deswal, Founder CEO, Innovant & Inspired Living (I2L), explains that façade materials critically impact thermal performance, energy efficiency, and sustainability. Glass façades enhance daylight penetration, reducing reliance on artificial lighting, but require Low-E coatings or double glazing to mitigate heat gain. While glass requires frequent cleaning, tempered or laminated variants improve safety and longevity.

Aluminium and steel conduct heat, necessitating additional insulation. Aluminium, known for its lightweight durability, benefits from reflective coatings to reduce heat absorption but needs anodising or powder-coating for longevity. Strong but prone to corrosion,

steel requires protective treatments to maintain its integrity.

With low thermal conductivity, wood provides natural insulation but requires sealing or painting to prevent decay and insect damage. Its lifespan depends on maintenance but can last decades with proper care.

Brick masonry façades have high thermal mass, helping regulate indoor temperatures and providing excellent insulation. Durable and low-maintenance, they are resistant to weathering, fire, and pests, requiring only occasional repointing of mortar joints. Similarly, concrete façades, though poor insulators on their own, perform well when paired with insulation layers, reducing cooling loads in hot climates.

Each material presents unique advantages and challenges. Thoughtful selection and integration of materials with insulation, shading, and protective treatments create energy-efficient, durable, and aesthetically pleasing façades that align with sustainability goals and climatespecific demands.

KEY OPPORTUNITIES AND CHALLENGES IN INTEGRATING SUSTAINABLE FAÇADE DESIGN WITH OTHER BUILDING SYSTEMS

Ar. Dhawan explains that one key challenge is ensuring that sustainable façades harmonise with architectural expression while meeting the technical requirements of engineering systems. The opportunity lies in leveraging advanced technologies like BIM (Building Information Modeling) to simulate and optimise these integrations early in the design process. With tools like CFD analysis, we can predict airflow, thermal performance, and structural stability, ensuring that all systems work cohesively.

Ar. Sanghavi highlights cost as a significant challenge in integrating sustainable façades with other building systems. “While sustainability is a growing

Integrating sustainable façade design requires a multi-disciplinary approach to align aesthetic, structural, and energy goals

priority, financial constraints often limit its full implementation. Many projects incorporate sustainable elements, but often in a limited or half-hearted manner due to budget constraints,” he says. However, from a technical standpoint, integrating sustainable façades with structural, mechanical, and MEP (Mechanical, Electrical, and Plumbing) services has become more seamless. “The industry has advanced significantly, and professionals are well-equipped to incorporate sustainability-driven solutions. The real challenge is securing the financial commitment to execute these strategies fully. Until sustainability is seen as a long-term investment rather than an upfront expense, cost will remain a primary hurdle,” he asserts.

Ar. Banaji emphasises that integrating sustainable façade design requires a multi-disciplinary approach to align aesthetic, structural, and energy goals. “The challenge lies in achieving synergy among systems without compromising on any discipline. Load-bearing façades must work with structural requirements, while shading elements should complement HVAC systems to reduce cooling loads,” he explains. However, he also sees opportunities, such as reducing redundancy and creating smarter, more efficient buildings.

Ar. Upadhyaya compares integrating sustainable façade design with other building systems to conducting an orchestra, where every element must work in harmony. “One of the greatest opportunities lies in energy efficiency. A well-designed façade can significantly reduce heating, cooling, and lighting loads, easing the strain on mechanical and electrical systems,” she states. “For example, a façade with high-performance glazing and external shading can minimise solar heat gain, allowing HVAC systems to operate more efficiently. Similarly, incorporating natural ventilation can reduce the need for mechanical cooling, especially in moderate climates.”

However, she acknowledges the challenges, particularly in coordination. “Architects, engineers, and consultants often work in silos, with each discipline focusing on its priorities. For sustainable façade design to succeed, collaboration from the inception is a must. This requires clear communication, shared goals, and embracing innovation and new perspectives,” she says.

Cost is another challenge, according to Upadhyaya. “Sustainable materials and technologies, such as double-skin façades or photovoltaic-integrated glass, often come with higher upfront costs. Their integration requires meticulous planning and collaboration, which can be time-consuming,” she explains. Predicting the long-term performance of innovative façade solutions also requires sophisticated tools and prototypes. “Convincing clients to invest in these solutions can be difficult, especially when benefits like lower energy bills and improved occupant comfort are longterm,” she adds.

Ar. Rajendran states that sustainable façade design cannot exist in isolation; it must integrate seamlessly with structural engineering, mechanical engineering, and architectural design. “Façades can enhance structural efficiency by

acting as load-bearing elements or providing additional stiffness. They can also integrate with mechanical systems to improve energy performance. For example, double-skin façades create a buffer zone that reduces heat transfer and can be coupled with natural ventilation systems to minimise HVAC loads.”

However, challenges remain. “Coordinating between disciplines can be complex, as architects prioritise aesthetics while engineers focus on performance. Cost constraints and technical limitations further complicate the process. Early collaboration and the use of tools like Building Information Modelling (BIM) are essential for overcoming these hurdles,” Ar. Rajendran notes.

Ar. Mohan emphasises that green aspirations crumble without interdisciplinary collaboration. He cites an example from an R&D facility in Vishakhapatnam, where architects, structural engineers, and MEP teams codesigned a north-light roof to harvest glare-free daylight while isolating lab service shafts towards heat-generating façades. “Challenges in such projects include convincing clients to invest in

integrated workflows. Yet, our Chennai Experience Centre, where Danpalon skylights and insulated standing seam roofing were prototyped with roofing pioneers, proves that collaboration cuts both costs and carbon.”

Dr. Deswal highlights the potential for façades to work synergistically with structural and mechanical systems to optimise energy performance. However, he points out challenges such as ensuring structural integrity while accommodating innovative façade designs. “Double-skin façades or ventilated façades improve thermal insulation, reducing reliance on HVAC systems. The integration of photovoltaic panels (BIPV façades) allows for on-site renewable energy generation. Dynamic façades with smart glazing or kinetic elements respond to environmental conditions, optimising thermal comfort, glare control, and natural ventilation.”

Furthermore, he notes that lightweight façade materials like ETFE membranes and composites reduce structural loads, enabling more cost-effective designs. Advances in parametric design, computational fluid dynamics (CFD),

and BIM facilitate façade optimisation in coordination with other building systems. “Smart sensors and IoT-driven façades can dynamically adjust ventilation, shading, and lighting, reducing operational energy consumption.”

However, he concludes that achieving an integrated façade system requires close collaboration between architects, structural engineers, mechanical engineers, and sustainability consultants. “Misalignment between disciplines can lead to design conflicts and inefficiencies. Additionally, integrating multiple systems necessitates customised solutions, increasing complexity and costs. Yet, fostering collaboration and innovation can break new ground in building design.”

COMBINING SUSTAINABLE FAÇADE SYSTEMS WITH BIOPHILIC DESIGN PRINCIPLES

Ar. Dhawan notes that integrating biophilic principles with sustainable façades is a natural extension of our design philosophy. Techniques like using perforated screens to frame natural views or incorporating vertical gardens not only reduce the urban heat island effect but also improve occupant satisfaction. These systems, when integrated with smart irrigation and drainage, achieve both environmental and aesthetic goals.

Ar. Sanghavi explains that integrating biophilic design with sustainable façade systems is now a necessity. “Traditionally, biophilic and landscape design focused on the ground level, but now it must extend vertically into façades. The postCOVID era has accelerated this shift, with greenery becoming essential in both residential and commercial spaces.

“In apartment design, for example, we see a resurgence of decks and landscaped pockets, as people seek a stronger connection to nature. This idea should begin with private decks and extend seamlessly into common areas such as lobbies, corridors, and façades. A well-

designed biophilic approach ensures greenery is not just aesthetic but a layered experience enhancing well-being and the building’s environmental performance.

“By incorporating living walls, vertical gardens, and green terraces into façades, we create immersive natural environments, improve air quality, regulate temperatures, and enhance energy efficiency. Common areas such as lobbies and shared terraces further integrate greenery, making buildings more human-centric, sustainable, and visually appealing. Ultimately, façades should evolve beyond mere enclosures to become dynamic, living elements that benefit both occupants and the environment.”

Ar. Banaji states that biophilic façades, such as green walls or planters integrated into shading systems, enhance indoor air quality, provide thermal insulation, and connect occupants to nature. “They promote mental well-being and reduce energy costs by acting as natural coolers.”

Ar. Upadhyaya explains that biophilic design reintroduces people to the natural environment, transforming buildings into dynamic ecosystems when combined with sustainable façades. “Green façades and living walls not only enhance aesthetics but also filter airborne pollutants and improve indoor air quality. They provide natural insulation, lowering energy consumption and mitigating the urban heat island effect. In urban areas with limited green spaces, they create biodiversity pockets, supporting local ecosystems and improving occupant well-being.

“Daylighting is another key aspect. Optimising window placement and size maximises natural light while minimising glare and heat gain. High-performance glazing, such as low-emissivity glass, enhances this effect, creating bright interiors that reduce reliance on artificial lighting. Studies show access to natural light improves mood, productivity, and well-being.

“Natural ventilation is another strategy. Operable windows, louvres, and ventilation systems allow fresh air circulation, reducing mechanical cooling needs and improving indoor air quality. This lowers energy consumption while syncing occupants with their outdoor environment.

“Finally, natural materials enhance biophilic façades, creating warm, authentic spaces. By integrating these principles with sustainable façade systems, we can craft environmentally friendly, human-centred buildings that nurture holistic well-being and strengthen the connection to nature.”

Ar. Rajendran highlights that green façades and vertical gardens enhance aesthetics, provide insulation, reduce urban heat island effects, and improve air quality. “For instance, the Podium Wall in Mumbai features a vertical garden that cools the building and creates a serene environment for occupants.”

He also emphasises the importance of natural light and ventilation. “Façades designed to maximise daylight and airflow reduce reliance on artificial lighting and air conditioning. Strategically placed windows, light shelves, and louvres optimise natural light while minimising glare and heat gain.”

“Biophilic façades reduce stress, enhance productivity, and improve well-being,” Ar.

Rajendran adds. “They also contribute to biodiversity by providing habitats for birds and insects.”

Ar. Mohan underscores functionality in biophilia, not just aesthetics. “At the Hyderabad residential tower, staggered terraces with soil-filled green pockets act as thermal buffers. Native species like snake plants and bougainvillaea thrive in recycled greywater, cooling adjacent apartments while filtering urban dust.”

He highlights another example in Chennai. “In the Experience Centre, a shaded central courtyard with indigenous trees uplifted indoor comfort, while polycarbonate skylights ensured diffused natural light. This blended biophilia with cooling systems, reducing energy loads.”

Maintenance is crucial, Ar. Mohan explains. “Drip irrigation lines are concealed, and users are trained to nurture their green pockets.”

Dr. Deswal notes that sustainable façades and biophilic design share common goals: enhancing occupant well-being, improving energy efficiency, and promoting ecological harmony.

“Green façades integrate climbing plants or hydroponic living walls onto building exteriors. They improve indoor air quality by filtering CO₂ and pollutants, add

aesthetic value, and enhance thermal comfort while reducing urban heat island effects through evapotranspiration,” he says, citing One Central Park in Sydney as an example.

Dr. Deswal further discusses biophilic shading devices, such as pergolas with vines or bamboo louvres, which control solar heat gain. “This reduces glare while allowing diffused natural light and creates dynamic light and shadow patterns, fostering a stronger connection to nature. The Bosco Verticale in Milan is a prime example.”

“Biomimetic façades, inspired by natural patterns like leaf venation, optimise daylighting and thermal performance,” he adds. “These designs enhance cognitive function and occupant productivity. The Al Bahr Towers in Abu Dhabi use a kinetic shading system inspired by Islamic Mashrabiya screens and natural patterns.”

He also highlights water features within façades. “Drip irrigation walls or misting systems regulate temperature and enhance biophilic engagement. In dry climates, they improve humidity levels, enhancing comfort.”

With biophilic design gaining traction, integrating nature into façade systems is proving to be an essential strategy for sustainable architecture, improving both environmental performance and occupant well-being.

MITIGATING RISING URBAN TEMPERATURES AND IMPROVING INDOOR AIR QUALITY THROUGH FAÇADE DESIGN

According to Ar. Dhawan, dynamic façades that respond to environmental conditions are key to mitigating heat waves and improving air quality. Materials like phase-change composites and doubleskin façades can reduce heat ingress, while integrating green elements, such as moss walls, can filter pollutants. These solutions provide comfort while enhancing sustainability.

Ar. Sanghavi highlights that large glass façades significantly contribute to the urban heat island effect by trapping and reflecting heat, raising city temperatures. To counter this, façade design must integrate shading elements, reduce heat absorption, and enhance ventilation instead of relying solely on glass structures.

Integrating biophilic design, perforated screens (jali work), and self-shading façade systems can mitigate heat waste. Green façades regulate surface temperatures by absorbing heat, while perforated panels enable passive cooling and controlled ventilation. These strategies not only curb the heat island effect but also enhance indoor air quality by promoting airflow and reducing mechanical cooling dependency.

Ar. Banaji stresses that façade designs must address rising temperatures with passive strategies such as shading devices, thermal insulation, and reflective coatings. To combat poor air quality, integrating air-purifying materials and green walls can act as natural filters, buffering against urban heat islands and fostering healthier indoor environments.

Ar. Upadhyaya highlights that highperformance glazing is crucial in mitigating heat waves and improving indoor air quality. Low-emissivity coatings

and double or triple-glazed windows significantly reduce solar heat gain, keeping interiors cool. Reflective coatings further minimise infrared radiation absorption. However, she emphasises that glazing alone is insufficient; external shading devices such as louvres, overhangs, and brise-soleil are essential to block direct sunlight while allowing daylight penetration.

Another innovative solution, according to Ar. Upadhyaya, is ventilated façades. These double-skin systems create an air gap between the outer façade and the building envelope, acting as a thermal buffer. During the day, this gap insulates the building, reducing cooling loads, while at night, it promotes natural ventilation by allowing hot air to escape. This not only enhances thermal comfort but also improves indoor air quality by facilitating fresh air circulation.

Green façades and living walls are gaining traction as urban heat island mitigation strategies. Plants absorb heat and release moisture through evapotranspiration, cooling the surrounding air while filtering pollutants such as particulate matter and volatile organic compounds. In cities like Delhi and Mumbai, where air quality is a major concern, green façades can be transformative.

Façades should be seen as dynamic components, integrating smart insulation, coatings, and shading systems to enhance energy efficiency and indoor comfort

Ar. Upadhyaya also points out that materials with high solar reflectance and thermal emittance can minimise heat absorption. Light-coloured or reflective surfaces can lower surface temperatures by up to 10°C, significantly reducing airconditioning loads.

Ar. Rajendran emphasises that façade design must address both heat mitigation and indoor air quality. He explains reflective coatings, shading devices, and ventilated façades can significantly reduce heat absorption. High-albedo materials reflect sunlight, lowering surface temperatures and cooling loads. In India, where heat waves are becoming more frequent, these strategies are crucial for building resilience. Façades can incorporate natural ventilation systems or air-filtering materials. Photocatalytic coatings, which break down pollutants when exposed to sunlight, are an emerging solution gaining attention, he notes.

Ar. Mohan advocates passive design as India’s best defence. He cites a Hyderabad school where brick-clad walls with 24inch recessed windows create a thermal mass that stabilises indoor temperatures. A tree-shaded courtyard serves as a cool-air reservoir, while roof ventilators expel heat.

At a Visakhapatnam pharma corporate office, stone cladding with a 4-inch air gap traps heat, which is naturally flushed out through strategically unsealed gaps, ensuring a breathable façade. “No greenwashing—just physics,” he asserts.

Dr. Deswal explains that façades embedded with photocatalytic coatings or green wall systems can filter pollutants, neutralise toxins, and reduce CO₂. Titanium dioxide (TiO₂) coatings break down NOx and VOC pollutants, while activated carbon-infused façade panels absorb airborne toxins. Green façade systems further help by capturing dust and filtering particulates, he notes.

Operable façade elements promote cross-ventilation, replacing stagnant air

with fresh outdoor air. Design features include wind-capturing façades (Venturi-effect designs that enhance airflow), stack-effect ventilation (where cool air enters from lower levels and hot air escapes through upper façade openings), and perforated façade panels for diffused airflow and pollution filtering.

“Some façade materials actively resist microbial growth, mould formation, and VOC emissions, thereby improving indoor air quality,” says Dr. Deswal. Key materials include non-toxic cladding (clay-based and lime-based façades), self-cleaning façades (photocatalytic and hydrophilic coatings to prevent mould and dirt accumulation), and copper- and silverinfused façade panels, which possess natural antimicrobial properties.

Façades with high solar reflectance (albedo) and low thermal emissivity prevent excessive heat absorption, aiding in heat wave mitigation. Dr. Deswal highlights several solutions: cool paints and coatings (high-reflectance ceramicbased coatings), light-coloured façade finishes (which reduce heat gain), and phase change materials (PCMs) that absorb and release heat.

Additionally, vegetated walls lower façade temperatures by 5–10°C, effectively reducing heat island effects. These measures collectively contribute to sustainable and resilient urban environments.

By incorporating these strategies into façade design, buildings can become more resilient to rising temperatures while providing healthier, more comfortable spaces for occupants. With the right design approach, façades can help mitigate the pressing issues of heat and pollution in urban spaces.

LEVERAGING DESIGN TOOLS, TECHNOLOGIES, AND COLLABORATIVE WORKFLOWS FOR HOLISTIC BUILDING DESIGN

Ar. Dhawan explains, “Technologies like parametric modeling and AI-powered design optimisation are transforming façade design. These tools enable us to simulate energy performance, airflow, and structural behaviour, ensuring every decision contributes to sustainability. By fostering a collaborative workflow, it can be ensured that every stakeholder’s expertise is reflected in the final outcome.

Ar. Sanghavi notes that modern building design is too complex for architects to work in isolation. “A holistic and sustainable approach requires collaboration with specialists—façade consultants, MEP engineers, structural experts, lighting designers, and more. Each discipline brings essential expertise, ensuring every aspect of the building functions optimally.”

“As architects, our role is like that of a conductor leading a symphony,” he continues. “We must orchestrate these elements seamlessly, allowing each expert to contribute while ensuring cohesion, efficiency, and sustainability. Advanced design tools and digital workflows have streamlined interdisciplinary coordination. Parametric modelling, BIM (Building Information Modelling), and real-time simulations improve integration, making the design process more informed and responsive.”

Ar. Banaji emphasises the role of technology in fostering collaboration. “BIM enables real-time collaboration among architects, engineers, and contractors,

Glass façade - The Shard, London by Architect Renzo Piano

ensuring all systems align seamlessly. Advanced simulation tools like energy modelling and daylight analysis optimise façade performance while maintaining design integrity. Collaboration fosters innovation, pushing the boundaries of sustainable design.”

Ar. Upadhyaya expands on this, stating, “Design tools and collaborative workflows are revolutionising building design. BIM allows teams to create detailed, three-dimensional models integrating all aspects, from façade to structural and mechanical systems. This improves coordination and helps resolve potential conflicts early, saving time and costs.”

She adds, “Energy modelling software is a game-changer. Tools like EnergyPlus and IESVE let architects simulate energy performance, testing façade designs to find the most efficient solution. By inputting data on solar orientation, climate, and building use, architects can optimise window placement, shading devices, and insulation to minimise energy consumption. This ensures sustainability goals are met without compromising aesthetics or functionality.”

“Parametric design is reshaping façades, unlocking new possibilities,” Ar. Upadhyaya continues. “Using algorithms to generate and evaluate multiple options, architects develop solutions balancing performance, cost, and aesthetics. For example, parametric tools optimise shading device orientation to maximise daylight while minimising heat gain.”

She underscores the importance of collaboration: “Involving all stakeholders from the beginning ensures everyone’s priorities are addressed. These tools and workflows push design boundaries, creating buildings that are visually appealing, sustainable, efficient, and resilient.”

With advanced technologies and a collaborative approach, façade design evolves to meet functional and aesthetic aspirations while embracing sustainability.

Ar. Rajendran highlights the complexity of modern façade design, emphasising the need for advanced tools and collaboration.

Design Tools: “Software like BIM, energy modelling tools, and parametric design platforms enable architects and engineers to simulate façade performance and optimise designs. Energy modelling predicts how different configurations impact energy consumption.”

Collaborative Workflows: “Early collaboration between architects, engineers, and contractors is crucial for holistic and sustainable designs. BIM facilitates this by providing a shared platform to coordinate façade systems with other building components.”

Ar. Mohan notes that BIM and parametric tools complement intuition. “For the Chennai Experience Centre, parametric roofs optimised Danpalon skylight angles to diffuse the harsh Tamil Nadu sun. In a Bangalore residential project, BIM helped strategically stack non-typical floorplans, forming a vertical villa development.”

Dr. Deswal explains that modern design tools, digital technologies, and interdisciplinary collaboration are essential for optimising façade performance and enhancing sustainability. “By integrating energy modelling, computational simulations,

AI-driven design, and immersive visualisation, stakeholders make datadriven decisions that improve energy efficiency, occupant comfort, and environmental impact.”

Building performance tools allow architects, engineers, and sustainability consultants to analyse façade design by simulating thermal performance, energy consumption, daylighting, ventilation, and renewable energy integration. Computational tools assess the impact of façade materials, orientation, shading, glazing, and ventilation strategies, helping determine insulation requirements, optimal U-values, and solar heat gain coefficients (SHGC). They also analyse wind flow and stack effect ventilation, supporting passive cooling strategies while optimising HVAC, renewable energy, and electrical systems.

Additionally, Virtual Reality (VR) provides an immersive experience, enabling stakeholders to visualise façade materials, daylighting effects, and shading systems before construction. Meanwhile, Augmented Reality (AR) overlays real-time performance data—solar heat gain, wind impact—onto site views, aiding informed decision-making and design refinement.

THE EVOLVING ROLE OF SMART AND ADAPTIVE FAÇADES IN THE INDIAN MARKET

Ar. Dhawan notes that adaptive façades represent the future of sustainable design in India. From kinetic shading devices to smart materials that regulate heat and light, these innovations cater to the diverse climatic zones of the country. They are particularly relevant in high-end residential and commercial projects where clients demand cutting-edge solutions.

Ar. Sanghavi emphasises that with rapid urbanisation and rising energy costs, energy-efficient façades are no longer optional but essential. Smart façades incorporating passive cooling, dynamic shading, and energy-efficient materials can significantly reduce energy

consumption, ensuring more sustainable urban environments. He likens this shift to the transition to electric vehicles, where increasing awareness is driving widespread adoption.

Ar. Banaji sees innovations like electrochromic glass and automated shading as game-changers, enabling façades to respond dynamically to environmental conditions, enhancing both occupant comfort and energy efficiency.

Ar. Upadhyaya describes India’s market as being at a crossroads, with growing demand for smart façades integrating IoT, sensors, and automation. Dynamic shading systems adjust in real-time, while photovoltaic panels generate electricity, reducing grid dependence. Adaptive façades are particularly valuable in India’s diverse climate zones, responding to variations in temperature, humidity, and sunlight. For instance, double-skin façades can regulate ventilation based on the time of day, enhancing comfort and efficiency.

Despite high upfront costs and maintenance challenges, Ar. Upadhyaya believes smart façades have immense potential. As technology becomes more affordable, she expects widespread adoption, making cities more sustainable and liveable.

Ar. Mohan offers a different perspective: “India’s ‘smart’ lies in cultural intelligence, not gadgets. The Hyderabad tower’s green pockets cost 5% of dynamic glazing but cut cooling loads by 18%. In Chennai, polycarbonate skylights— cut by industry experts—significantly reduced heat gain. Even the Visakhapatnam R&D facility’s north-light roof relies on century-old principles rather than sensors. Smart design is silent—it works without demanding attention or budgets.”

At Architecture Dialogue, sustainability is a conversation, not a label. “The Hyderabad tower’s green pockets will mature with residents, the Visakhapatnam stone will wear salt-spray patinas, and the Chennai roof will perform as well as the trees beneath it. In a market chasing ‘iconic,’ we build quiet resilience—yet iconic,” Ar. Mohan adds.

Dr. Deswal highlights India’s high cooling loads, air pollution, and rising energy demand, making smart façades critical. “With buildings accounting for 35% of total energy consumption, dynamic shading, ventilated skins, and smart glass can reduce cooling loads by up to 30%, significantly lowering electricity costs.”

Government regulations like the Energy Conservation Building Code (ECBC) and green certifications such as LEED and GRIHA are driving smart façade adoption. “Smart façades integrating renewable energy (BIPV panels) and AI-driven shading align with India’s Net Zero Energy Buildings (NZEB) vision. With severe air pollution in cities like Delhi, Mumbai, and Bangalore, airfiltration façades using photocatalytic coatings and ventilated systems can help reduce PM2.5, PM10, and VOCs,” he explains.

However, challenges remain. “High costs deter the adoption of electrochromic glass, while humidity and pollution can

affect kinetic façades and automated shading. But government incentives and green financing could accelerate this transition,” Dr. Deswal notes.

CONCLUSION

The intersection of façade design and technology has unlocked unprecedented possibilities in creating energy-efficient, high-performance building envelopes. Today’s architectural landscape is witnessing the seamless integration of software-driven solutions such as parametric modelling, AI-enhanced automation, and real-time energy simulation, which enable precise control over factors like thermal regulation, daylight optimisation, and natural ventilation. Tools like BIM, Grasshopper, and AI-driven analysis platforms allow architects to visualise, test, and refine façade elements to ensure optimal performance while maintaining design integrity.

Beyond efficiency, these advancements facilitate innovation in sustainability. Smart façades equipped with electrochromic glazing, kinetic shading devices, and biophilic elements are transforming the way buildings interact with their surroundings.

It’s like creating a bridge between the natural world and our built environment, where both can thrive together!

Due to rising urban temperatures and air quality concerns, how can façade design reduce the impact of heat waves and improve indoor air quality?

Façades play a crucial role in protecting buildings and their occupants from heat waves and poor air quality, much like how an umbrella shields us from the sun and a mask filters out dust. Think of the building façade as a smart shield that helps keep indoor spaces comfortable and healthy.

To combat heat waves, façades can use special materials and designs that reflect sunlight, similar to wearing light-colored clothes on a hot day. External shading devices, like giant blinds or louvers, block excessive sun while still letting in natural light. Double-skin façades work like a thermos, creating an air gap that insulates the building from extreme temperatures.

For better air quality, façades can incorporate natural ventilation systems –imagine windows that automatically open when the air is clean and close when it’s polluted. Green walls with living plants act as natural air filters, removing pollutants while adding oxygen. Smart façades can also include air filtration systems that clean incoming air, much like an air purifier in your home.

These features work together to create healthier, more comfortable indoor spaces while reducing the need for

excessive air conditioning and artificial ventilation, making buildings more environmentally friendly and energyefficient.

5. How can design tools, technologies, and collaborative workflows facilitate a more holistic and interdisciplinary approach to building design, optimising

façade performance, and achieving overall building sustainability?

Think of designing a sustainable building like playing a sophisticated video game where different players (architects, engineers, and sustainability experts) work together using special tools. Here’s how modern technology helps them create better buildings:

Building Information Modeling (BIM) works like a digital LEGO model where everyone can see and work on the same building simultaneously. For example, while architects design beautiful windows, engineers can immediately check if they’re energy-efficient, and sustainability experts can analyse their environmental impact –all in real time.

Simulation tools act like weather forecasts for buildings. They can predict how a building will perform in different conditions. For instance, they can show how much energy glass windows might waste in summer or save through natural light in winter.

Digital collaboration platforms work like multiplayer games where team members share ideas instantly. If an

architect changes the façade design, engineers immediately see how it affects the building’s structure and energy use.

6. How do you see the evolving role of smart and adaptive façades in the Indian market?

Smart and adaptive façades in India are gaining momentum, particularly with initiatives like the Smart Cities Mission and green building regulations. A practical example is Kohinoor Square in Mumbai, which uses automated solar-responsive façades, though simpler than complex systems seen in buildings like Al Bahar Towers in Abu Dhabi.

The Indian market is realistically moving towards cost-effective smart façade solutions. Government projects like the new Parliament building incorporate basic smart façade elements such as double glazing and solar shading. Future developments in cities like Gujarat GIFT City and Mumbai’s BKC smart city project are expected to implement moderately advanced façade systems that balance innovation with practicality.

Looking ahead, India’s tropical climate and energy challenges will likely drive the adoption of affordable smart façades focusing on:

• Basic automated shading systems for energy efficiency

Security is a primary concern for any homeowner or building occupant. A multipoint locking system, like those from Insta Hardware, secures the window at multiple points along the frame rather than relying on a single lock. This makes it significantly more difficult for intruders to force entry, providing an added layer of protection. With increased break-in resistance,

multipoint locks are a preferred choice for modern residential and commercial buildings. A well-sealed window contributes to better energy efficiency and indoor comfort. By engaging multiple locking points, these systems ensure a tighter seal between the sash and frame. This reduces air leakage, minimises draughts, and improves thermal insulation, leading to lower energy costs. Additionally, the enhanced sealing also helps in reducing external noise infiltration, making interiors quieter and more comfortable.

Large aluminium windows are prone to warping or misalignment over time due to uneven pressure when opening and closing. A multipoint locking system from Insta Hardware distributes pressure evenly across the frame, preventing these issues. This ensures the longevity of the window, maintaining its structural integrity and smooth functionality over the years. Windows should be easy to operate without excessive force. Highquality multipoint locking systems

facilitate a smoother opening and closing mechanism, reducing strain on the hardware. This not only enhances user experience but also prolongs the lifespan of the window components, reducing the need for frequent maintenance or replacements.

Modern multipoint locking systems are designed to be concealed within the window frame, ensuring a sleek and uninterrupted aesthetic.

Considerations for Corner Joints When Selecting High-Quality Aluminium Windows

What should be considered regarding corner joints when choosing high-quality aluminium windows? What sets system aluminium brands apart from others? It is well understood that quality lies in the details. Therefore, it is essential to begin by examining the quality of corner joints, one of the most critical aspects of a superior window system.

• The corners of aluminium windows are typically joined using mechanical connectors, which can loosen over time due to daily use, leading to gaps in the joints.

• Uncoated aluminium oxidises when exposed to atmospheric conditions. During assembly, window corners are cut, leaving uncoated edges that are vulnerable to corrosion. Over time, this corrosion spreads beneath the powder coating or other surface treatments, resulting in surface swellings resembling worm-like filaments. This phenomenon, known as filiform corrosion, also referred to as under-film or filamentary corrosion, occurs beneath thin organic coatings

such as powder coating or paint. It affects metals like aluminium, magnesium, steel, iron, and zinc.

• Filiform corrosion is particularly prevalent in warm, humid environments and originates at coating defects or weak points, such as cut edges, scratches, or holes. India’s climatic conditions are conducive to the development of this type of corrosion. It manifests as thread-like filaments that spread in random directions from the defect, resembling worm tracks. The corrosion process involves water and oxygen migrating under the coating, where the filament

head functions as the anode, leading to metal dissolution, while the tail serves as the cathode.

• While all windows experience some level of rainwater leakage, it is crucial that any infiltrating water is properly drained before it reaches the interior. Aluminium windows, having mechanically connected corners that are not inherently watertight, allow water to seep through the joints until it reaches the discharge channels.

SOLUTIONS TO ADDRESS THESE ISSUES

Corners joined using cleats or crimping methods can loosen over time. To prevent this, the integration of hydrolysis-resistant polyurethane-based corner adhesives is recommended. These adhesives reinforce window corners, ensuring durability and stability.

Weiss offers two specially formulated products for this purpose: the singlecomponent COSMO PU-100.130 and the double-component COSMO PU200.280, both tested and approved by IFT ROSENHEIM. These adhesives enhance the strength of corner joints, prevent mechanical loosening, increase window lifespan, maintain structural integrity, improve comfort, and reduce maintenance costs.

Leading window brands employ IFT ROSENHEIM-approved corner adhesives, with Weiss serving as a key solution partner for respected system houses worldwide.

Weiss also offers a specialised hybridbased coating to prevent filiform corrosion at window profile cut edges,

Product Watch

providing 1680 hours of salt resistance on raw aluminium. This advanced coating is particularly effective in capillary gaps, ensuring flawless adhesion and excellent water and air insulation at the corners. Without this protective coating, joint leakage is inevitable.

It is worth noting that the stated 1680hour salt spray test value has been tested and certified by ILAK for COSMO HD-100.410, which is specifically recommended for this application.

One common cause of whistling windows during high winds is inadequate corner sealing. Several industry professionals and technicians seek to improve their product quality by referring to Weiss’s instructional videos on social media. Many mistakenly assume that Weiss adhesives are silicone-based due to their plastic cartridge packaging, similar to silicone. However, silicone is not a suitable sealant for corrosion resistance, as it requires a minimum gap of 5 mm for effective application. Applying silicone in smaller gaps is incorrect, as it fails to function efficiently in these areas. Those prioritising quality can achieve optimal results by using the appropriate products.

This hybrid coating can be applied to raw aluminium surfaces for robust protection, including holes created during window manufacturing, such as those for water drainage channels and handles. It ensures that windows remain flawless from every angle.

Weiss also provides cleaning solutions that are safe for powder-coated surfaces, designed to remove cutting cooling oils and dust both before and after the application of adhesives. These solutions also help eliminate any excess adhesive that surfaces postapplication.

For decades, Weiss has been synonymous with top-tier adhesive and sandwich panel technology. By consolidating these core competencies under one roof, the company is uniquely positioned to provide customers with

comprehensive and highly efficient solutions at a superior technical standard.

Since its founding in 1815, Weiss has remained dedicated to quality and continues to meet the high expectations of its customers. This commitment has established the company as a trusted

and reliable partner not only in Europe but also globally, with a presence in markets ranging from China to the United States.

Weiss products are now easily accessible in India. Manufactured by robots in Germany to German technology standards, these products are stored in climate-controlled warehouses in India and delivered to customers in pristine condition.

It is strongly recommended to experience Weiss’s superior protection and adhesion capabilities without delay, ensuring the production of impeccable windows.

To assess the quality of a window before purchase, it is advisable to closely examine corner joint details and inquire about Weiss products from the window supplier.

Ensuring Clarity when Specifying Passive Fire Protection for Façade Systems

Specifying the most appropriate firestop and cavity barrier solutions for any façade system can be challenging. With multiple manufacturers offering similar products that have been tested to different standards - and sometimes no clear guidance from the national building code as to which are the most suitable - the onus is often on the building or system designer to conduct their due diligence and ensure that the selected safety measures are not only suitable for their application but also that they can confidently verify any performance claims.

This process often involves reviewing a range of product information, typically spread across numerous documents such as technical datasheets, independent test certificates, third-party listings, standard details, and more. Additionally, acquiring

these documents from manufacturers and distributors, or collating them from various websites, can be a time-

consuming and laborious task. That is why some manufacturers of life-safetycritical products have developed their own digital Specification Packs for façade consultants and designers, architects, fire engineers, developers, and specifiersproviding quick and convenient access to a single source of up-to-date technical information for straightforward and safer specifications.

WHAT ARE SPECIFICATION PACKS?

Specification Packs function almost like an encyclopaedia of product information. Typically, centred around a specific façade application type - such as curtain wall or cladding systems - they concisely summarise all the relevant technical information needed for robust and accurate specifications, with live links to key downloadable documents and data sources.

For example, the specification packs are available for curtain walls, external cladding (both ventilated and nonventilated), and precast and sealed external wall applications. They include:

to ensure accurate

Siderise has launched a suite of new digital application-specific Specification Packs to support designers in collating the rich technical data they need to choose the best passive fire protection solutions for their projects

packs can help ensure decisions are backed by robust data and justified with the appropriate level of detail

• Technical datasheets

• Third-party certification

• Standard detail drawings

• BIM objects

• Specification information and clauses

• Installation instructions

• Environmental performance Declarations

These packs can usually be downloaded free of charge and without a forced sign-up from the manufacturer’s website, ready to be used whenever and wherever project specifications need to be created. Since they are digital documents rather than printed product books or brochures, all information and links can be periodically checked and updated by the manufacturer, ensuring that users always have access to the most up-to-date data and certifications.

This reduces the risks associated with outdated material, such as inadvertently specifying a product whose performance has changed, which could result in failing to meet a project’s performance requirements. At best, this might incur additional costs and time to rectify the issue. At worst, inappropriate product selection could severely compromise a building’s safety, with potentially

devastating consequences in the event of a fire.

Furthermore, while they can complement and integrate with digital specification platforms - often containing links to relevant resources - they are also available as standalone PDF documents that do not require designers to have access to any specific software or licences. This makes them widely accessible and relevant to projects across the globe.

ADDED EXPERTISE

Of course, accessing all the relevant product or system information is just the beginning. Passive fire protection is a complex yet safety-critical aspect of façade design, and those selecting solutions must have access to technical support from the earliest design stages. Early involvement can help to ensure that the products chosen for the project are suitable for the intended application while also meeting compliance criteria and being appropriately cost factored - reducing the risk of inadequate substitutions later in the construction process.

Specification packs typically include details of the services available from manufacturers themselves. As experts in their products, manufacturers can assist with project-specific specification

guidance, ranging from product selection advice and calculations to helping prepare and review drawings.

Some of the added-value services include:

• Design feedback

• Technical datasheets and parameter guidance

• Example detail drawings and AR 3D visualisations

• Standard details of example façade arrangements

• Project-specific product suitability advice

• Technical detail drawing reviews and overlays

• Method statements and sequencing information

• Mock-up constructions and product samples

• Project-specific fire testing

Often, Specification Packs also direct specifiers to the most relevant training courses and CPD modules for their specific application. For passive fire protection in particular, understanding how product performance is measured and how a product should function can make it easier to review and compare technical information from different suppliers and ensure that the correct test standards have been used.

SUPPORT AT YOUR FINGERTIPS

Ensuring the fire safety of our buildings must be a top priority across India. Specification Packs, like those developed by Siderise, can help designers across the region easily access all the information and support they need to integrate appropriate passive fire safety measures into their designs from the outset, protecting people and property in the long term.

Elevating Building Fa ç ades with Greenlam Exterior Clads: Style, Durability, and Sustainability

In architecture and design, the exterior of a building serves as its first impression—a canvas that reflects its style, character, and functionality. With homeowners and architects increasingly prioritising both aesthetics and sustainability, high-pressure laminate (HPL) wall cladding designs have become a key component of modern architecture, seamlessly combining visual appeal with practical benefits. HPL exterior compacts not only enhance a building’s façade but also contribute to improved energy efficiency and weather resistance.

FINDING THE RIGHT CLADDING

Exterior-Grade compact laminates by Greenlam Clads offer an excellent blend of style and practicality. It is a suitable alternative to natural materials like stone, brick, or marble, being an eco-friendly and sustainable option. Compared to materials like wood, it is more cost-effective and highly durable. Its lightweight nature makes it easy to handle during installation for facades and exterior applications. Additionally, Clads are designed to withstand various elements, including harsh UV rays, termites, moisture, chemicals, dust, and acid rain, ensuring that the cladding maintains its aesthetic appeal for years. High-quality laminate cladding does not fade, stain, or suffer damage easily, making it an ideal choice for extreme cold, heat, or rainfall.

FINDING THE RIGHT DESIGN OPTIONS

When selecting exterior laminate cladding, it is essential to choose a design that complements the property’s overall vision. For a modern, urban structure, a solid colour with a suede finish can create a sleek and contemporary look. On the other hand, woodgrain or stone-inspired exterior-grade compact laminate cladding designs are perfect for a warmer, cosier vibe.

Neutral tones, such as beige or grey, are ideal for creating a minimalist and timeless façade, while brighter shades or textured finishes can make a bold statement. Greenlam Clads exterior compact laminates can be customised to meet specific site and design requirements, allowing for tailored solutions to suit various fabrication needs.

Iba Powder Coating: Elevating Quality, Consistency, and Sustainability in Modern Coatings

KEY FEATURE THAT MAKES IBA POWDER COATING SYSTEMS ESSENTIAL

Iba is a well-regarded brand known for its strong emphasis on quality in the powder coating industry. It is trusted by major brands across multiple industries, including the white goods sector. A key reason for this preference is Iba’s rigorous quality control process, which ensures consistently high standards. This process includes strict monitoring of raw material selection, acceptance, test trials, production samples, and stock samples, with regular quality checks. Any products that fail to meet the required criteria are promptly rejected.

One of the most pressing challenges currently faced by the powder coating industry is colour inconsistency between batches, along with surface defects such as orange peeling. Even products from leading market players are not entirely immune to these issues, creating significant challenges for coating professionals.

Manufacturers who prioritise quality choose Iba for a more reliable production

process. Iba upholds its quality commitment through strict policies and recognised certifications. Its powder coatings are QualityCoat approved, with warranties that reflect its dedication to excellence.

While maintaining high-quality standards, Iba also places a strong focus on environmental sustainability. It has eliminated lead-containing raw materials from its standard production range and integrates renewable energy sources into its manufacturing processes.

For façade and window projects, Iba’s solutions meet the critical requirements of durability and aesthetics, ensuring long-lasting performance. By using Iba’s

coatings, surface irregularities such as orange peeling caused by paint quality are minimised, and colour inconsistencies are effectively eliminated.

To further support architects and façade consultants, Iba has introduced bonded colour technology at no additional cost for their first project. This initiative aims to familiarise industry professionals with bonding technology in powder coating systems, helping them achieve superior results.

Understanding bonding technology is essential for those looking to optimise coating performance.

Since the early 2000s, metallic powder coatings have been widely used across various industries, including architecture, metal furniture, and domestic appliances. These coatings are produced using two main methods: dry blend and bonding. To achieve a metallic powder effect, three types of pigments are commonly used: leafing aluminium, non-leafing aluminium, and mica effect pigments.

The bonded powder coating process enhances the performance and application characteristics of metallic or effect powder coatings. This method fuses metallic or special effect pigments to the base powder particles using heat and mechanical energy. As a result,

it significantly improves consistency, durability, and aesthetic quality.

KEY BENEFITS OF BONDED POWDER COATING

• Improved Consistency – Bonded coatings offer a more uniform colour and effect, reducing variations compared to dry-blended powders.

• Enhanced Application Efficiency–These powders charge more effectively, leading to higher

Product Watch

transfer efficiency and reduced waste.

• Better Recyclability – Overspray from bonded powders can often be reclaimed and reused, unlike dryblended powders, which tend to separate during recycling.

• Increased Durability – The bonding process reduces the risk of pigment detachment, improving long-term performance.

• Minimised Clouding and Striping–Ensures a more even distribution of metallic or effect pigments, reducing defects such as cloudiness or striping in the final finish.

In dry blend metallic powder coatings, metallic pigments are physically mixed with powder coating particles. Due to differences in density, pigments may settle after packaging and transportation. As a result, users must thoroughly mix the powder before application to maintain a uniform finish.

In contrast, bonded metallic powder coatings involve a chemical bonding process at controlled temperatures, ensuring a more stable and homogeneous product.

While achieving these high-quality standards, Iba remains committed to environmental responsibility. It has completely phased out leadcontaining raw materials from its standard production and continues to use renewable energy sources in its manufacturing.

In conclusion, if you are an architect or façade consultant looking to integrate metallic colours into your project and achieve flawless application, you can access bonding technology in your first project at no additional cost.
