Façade Engineering Accommodating Movements in Façades
The connection between a building’s façade and its primary structure is like a duo dance posing some tricky challenges! So, when the structure decides to groove and shake, the façade can’t help but follow along. If we don’t address this dance routine early in the design process, the consequences can be a real showstopper!
By delving deeper into the relationship between the façade and primary structure, we can gain a better understanding of the complexities involved and the critical role that careful design and engineering play in ensuring a harmonious performance.
The movements experienced by buildings are primarily due to live loads such as users, wind and seismic activity in addition to temperature and moisture fluctuations. These forces can cause the building to sway, vibrate, or deform to some extent. Since the façade is an integral part of the building envelope, it experiences these movements as well. Different façade components respond differently to these forces for several reasons such as:
• Thermal Response: Different materials used in construction have distinct thermal properties and hence when exposed to temperature fluctuations, these materials expand or contract at different rates. For example, metals generally have a higher coefficient of thermal expansion compared to glass or concrete. This can lead to stresses and movements within the façade system, potentially causing challenges in maintaining structural stability.
• The movement of façade elements due to thermal effects needs to be considered during the design and construction stages and adequate structural support and connection details should be provided to accommodate thermal movements.
• Material Characteristics: The choice of materials can influence the behaviour of the façade to external forces. For example, metals, concrete and plastics exhibit different degrees of flexibility, contributing to variations in how different building components, such as façades, beams and columns, respond to applied loads.
• Construction Techniques: Advancements in construction techniques have introduced innovative methods and materials that allow for greater architectural freedom and efficiency. However, these modern techniques may also introduce additional complexities in managing structural movements.
• For example, light weight construction materials might offer cost and design benefits but could result in higher deflections under load. This can impact the alignment, performance and integrity of the façade elements. Excessive movement can also lead to issues such as misalignment of panels, stresses on fixings or connections, increased risk of water penetration and compromised aesthetic appearance.
• Architectural Elements: The design of architectural elements within a building can significantly influence its response to movements. Features such as cantilevered façades, large-span
The façade is like the stylish outfit that the building wears
External fixings can also restrict the natural movement of façade elements creating excessive stress on the façade system
roofs, or intricate geometries can introduce unique challenges due to various dynamic loads, such as wind, vibrations and seismic forces. External fixings play a crucial role in transferring these loads between the façade elements and the building structure and if the fixings are not designed to accommodate dynamic movements, they may cause excessive stress on the façade system. This can lead to fatigue failure, loosening of fixings, or even detachment of façade elements.
• External fixings can also restrict the natural movement of façade elements creating excessive stress on the façade system. This can result in material deformation, cracking, or failure of the fixings, cladding panels, or the overall façade assembly.
Effective mitigation of the issues associated with movements in façades requires consideration of key factors in design, construction and maintenance.
1. Coordination with Structural Team - For almost all types of façades, the dead load of the system and associated supports along with the different applied loads are carried by the primary structure of the building.
Failure to provide a sufficient allowance for in-service movements in the connections between the façade and structure will result in the load being transferred through elements of the building envelope, which they are not designed to carry. This may result in leaks, cracks in brittle elements, failure of connections, buckling of mullions and breakage of glass.
To avoid these problems, the structural designers need to engage with the façade contractor’s designers to understand the requirements & limitations of the façade bracketry. Structural elements should be chosen such that the movements which the cladding has to accommodate are reasonable and unusual movement
Façade Engineering
requirements are not imposed on the cladding.
It is also important for the structural engineer to provide his movements report to the façade designer, enabling the façade team to cross-verify the fixation capacity. See the image for a sample deflection report of primary elements, which allows the façade engineer to gauge the movement allowance to be provided for his façade elements.
2. Customisation & Adaptation:
Façade systems need to be customized to suit the specific requirements of the project.
Stick curtain wall systems: Stick
curtain wall systems, while flexible and customizable, have limitations to accommodating significant building movements. The individual mullions and transoms are connected using mechanical fasteners, which may not allow for large amounts of movements. If excessive movements are induced
in the system, it can lead to joint failure, resulting in leaks, cracks, or compromised system performance.
Unitized curtain wall systems: Although limited in their flexibility and customization, is advantageous in accommodating building movements. The prefabricated units can be designed to accommodate a greater range of movement while maintaining the integrity and performance of the system. Unitized systems can effectively allow expansion joints within the system using flexible gaskets and elastomeric materials depending on the anticipated movement and design requirements. Unitized systems are also capable of accommodating sliding connections using specially designed brackets, clips, or sliding rails that allow the units to move while maintaining their structural integrity.
When large deflections and movements are anticipated, it is always advisable to design a unitized curtain wall system. See

External Connections: It is a common practice these days that the building façade is integrated with external shading devices. These elements ensure greater indoor comfort levels as they block sunlight and reduce the amount of solar gain.
While the external shades are great for the energy efficiency of the building, it is important to carefully design the connections of these elements to the main structure. Most of the time, the connections are penetrated through the façade joints, to be fixed back to the main structure.
The façade elements and shading devices may experience different rates of movement and if the connections through the façade joints do not allow for independent movement of the shades and the façade, it can lead to compromised weatherproofing creating potential points of entry for air and moisture.
Lack of movement in the connections can also lead to localized stress points, potentially causing cracking, deformation, or failure of the façade elements.
The connections through the façade joints can also create thermal bridging, undermining the energy efficiency of the building, resulting in increased heating or cooling loads. Thermal bridging can also contribute to condensation problems within the façade, leading to moisture accumulation, mold growth and degradation of building materials.
Hence careful design considerations are required when installing external shading devices. During the design stage, attention should be given to the placement and configuration of external connections and flexible connections, or joint systems must be employed, that allow for relative movement between the shading devices and the façade elements. This will help mitigate movement issues at façade joints and using thermal breaks around the connections will allow for efficient thermal performance of the system.
Effective collaboration among the design and construction team and adherence to quality control measures are key to successfully integrating new construction methodologies and innovative façade elements and materials while ensuring the performance and stability of the façade system.

The Changing Windowscape in the Indian Sub-continent
Being in the window industry since 1999 in various capacities and companies gave me a unique opportunity to see the change in the window industry in the last 2 decades.
Window sizes were smaller - 4’ x 4’, 6’x4’; window openings had shades (chajjas), and there was no concept of testing. When I used to talk about tests and performance, I was told, our window has been functioning perfectly well for so many years. Domal was opposed vehemently, PVC was almost ostracised. Glass was from 3mm to 5.5mm. Thicker glasses and Double Glazed Glass for windows was very very limited. Sun films and tinted glass fought against each other to offer sun protection.
Entry of major European uPVC profile companies, aluminium system companies, hardware companies and performance glass brought in concepts
of energy saving, noise reduction and functionality of windows beyond just opening and closing.
However, installation still posed a big challenge. Good window installed badly = bad window.
In the meantime, the façade industry was growing rapidly in terms of technologyunitised façades became more common. Façade testing started & people started taking leakage of air and water, structural performance and acoustic insulation more seriously. IT companies demanded bigger offices with shimmering glass façades.
Many of the window producers were attracted to the façade market and aluminium windows became poorer cousins of uPVC windows. uPVC windows started to grow rapidly especially in the southern region of India as the window sizes were still comparatively less challenging than in the west and north. As there was a big gap between a big aluminium window producer and a smaller low-cost producer, uPVC filled in. The visible problems such as poor powder coating, gaps in window corners, and poor hardware were easily solved by uPVC windows with welded corners and multi-point locking hardware.
Fenestration
2010 onwards saw a major change in building construction. Taller buildings, bigger windows, performance testing and engineered windows.
Tall buildings and faster construction due to formwork construction led to bigger projects which started to attract the aluminium players back to the window market. Aluminium system companies started to push for testing and performance. Installation in highrise buildings was a challenge as only a skilled façade producer could handle it. High performance in terms of structural stability with less weight and thinner sight lines for these tall buildings made it easier for aluminium.
Formwork construction and lighter outer wall construction design for more economical and faster construction led to bigger windows. The heights of windows began to increase to 6’ and then 7’; doors from 7’ to 8’ and now almost 10’ in many projects.
Some feel a bigger size means less cost/Sq ft. But actually, a bigger size means stronger mullions to prevent
deflection against strong winds. Cost doesn’t necessarily drop unless one just uses it without any design or structural calculation. This could be dangerous in case of cyclones or storms.
The introduction of glazing in the National Building Code has brought in some awareness, especially in the usage of safety glass. The glass industry has strived hard to lobby for the right use of glass in buildings. Sometimes the focus is only on the glass and not on the framing material or performance of the window as a whole unit.
For the last couple of years, the Bureau of Indian Standards has started to push the industry to usher in standards for profiles, doors and windows. The cooperation between all major players, government and testing agencies is laying the foundation for new-generation windows and window technologies. These standards will drive “Make in India” and create opportunities in not only window production but also in hardware, gaskets, installation, software, management, testing and finance. Truly exciting times ahead!

the implications of the weight and properties of natural stone, early on in the design work. Weight is the primary area of concern when building with stone. Fundamentally, you are talking about adhering or attaching a very heavy material to a vertical surface.
The installation process requires ensuring that each stone finds its place within the design while considering load distribution, thermal bridging and material compatibility.
Dry cladding directly on the structure of a building is a construction technique where cladding materials are attached directly to the main structural elements, with or without the use of a substructure made of steel or other framing materials. This method is often referred to as “direct-fix” or “face-fixed” cladding. In this approach, the cladding material is typically secured to the building’s surface using fasteners, such as screws or nails. The fasteners are directly driven into the structural substrate, providing a secure and stable attachment for the cladding. Two common types of fasteners used in dry cladding are regular fasteners and undercut fasteners, which have a unique design that allows for a hidden attachment, which means the fastener remains concealed behind the cladding material. This provides a clean
and seamless appearance to the exterior surface of the building.
Natural stone’s unique thermal properties offer a great advantage when it comes to energy efficiency. Its high thermal mass enables it to absorb, store, and gradually release heat, regulating indoor temperatures. This quality helps keep the heat out when it’s warm, which means we rely less on air conditioning and use less energy overall. This synergy with nature’s rhythm not only slashes utility bills but also promotes sustainable design strategies. Natural stone cladding also contributes to improved acoustics within architectural spaces. The dense composition of the stone helps dampen the sound vibrations, creating tranquil interiors and shielding inhabitants from external noise pollution. As urban landscapes grow louder, the value of acoustically enhanced environments becomes ever more apparent, making natural stone cladding an asset in fostering serenity within bustling cities.
From ancient wonders to modern times, the journey of natural stone cladding epitomises architectural evolution. Natural stone cladding is a marvel that harmonises durability, aesthetics, and ecological sensitivity. It creates spaces that breathe elegance and resilience while embracing sustainable principles. As architects and designers embrace the heritage and promise of natural stone cladding, they shape not just structures, but a greener future.

An Odyssey in Stone
The New Parliament House, New Delhi
Some projects are chosen, not only for the legacy associated with them but also for the significant scale and timeline that demands collective and individual efforts from the entire organisation. The specialised stone latticework at the New Parliament House, New Delhi, in collaboration with Tata Projects, was one such landmark project in the history of our organisation. We, at Odyssey, were entrusted with the responsibility of creating the exterior and sandstone lattice screens for this iconic structure—the first purpose-designed Parliament building in India, in an extremely demanding timeline. It required each individual, and the entire organisation as a whole, to step up and tackle this head-on.
As a specialised fabricator and installer, our task involved procuring, sawing, carving, finishing, and installing 290 metric tonnes of Dholpur sandstone in
the form of 70mm thick lattice screens. We source material directly from the quarry, to ensure consistency of raw material and two members of our team were stationed at the quarry during the entire procurement process.
Simultaneously, we began the design and prototyping process which required close to 500 square feet of lattice prototypes in varying degrees of intricacy. We had to strike the right balance between achieving the correct degree of intricacy with the finer tools (such as the pencil/6mm diameter tool) along with fabricating within the stipulated period. These prototypes were then placed at the heights they would be viewed for final approvals from the design team.
The lattice screens, totaling 14,200 square feet, are 3-dimensionally carved on the face and 2-dimensionally honed from the

back side, as they would be visible from the inside of the building. This intricate work required over 75,000 CNC milling hours, 60,000 hand-finishing hours, and 25,560 man hours for installation. Over 45 CNC machines, operating for 22 hours a day were dedicated to this project and a team of 30 finishing craftsmen hand finished.
The lattice screens are installed at a height of 80 feet and were pre-installed with undercut fasteners, and mechanical fasteners to streamline the delivery and installation process. Due to the sheer number of agencies simultaneously involved in finishing this monumental project, every second and square foot on the job site was accounted for. This required precision to the highest degree, and we had to create stencils of every individual metal sub-frame, and mark them on each lattice for the positioning of the undercut fasteners.
There are a total of 78 full lattice panels, which are a composition of nine individual panels. Each lattice panel, with outer dimensions of 2400mm x 600mm x 70mm and weighing 750 kilograms each, was installed at a height of 80 feet.
The meticulously crafted sandstone lattice screen draws inspiration from the country’s rich architectural heritage.
Odyssey’s contribution to the new Parliament building in New Delhi is a testament to our commitment to excellence and dedication. The sandstone lattice screens will stand as an enduring symbol of beauty and functionality, illuminating the interior spaces with a touch of tradition. As we continue to grow and evolve as a company, we take immense pride in leaving a lasting legacy that showcases our passion for artistry and innovation.

Cladding New Wall Cladding Systems
The word façade originally comes from the Italian word “facciata”, and is defined as the outside or all of the external faces of a building. The term is frequently used to refer just to the main or front face of a building.
Along with the roof, cladding is one of the most important elements of a building, since it acts as the primary barrier against external weather elements that could damage the health of the structure, such as rain, snow, wind, frost, sun, etc.
Because of this, it is very important to choose a façade system that protects against these risks whilst helping to achieve lower energy consumption, reduce maintenance costs and improve comfort for the inhabitants.
Contemporary homes are unique for their incorporation of multiple architectural styles. While they feature the minimal adornment, open spaces and large windows of modern homes, they are also characterized by free-form composition not found in modernist architecture.
With today’s technology, architects are no longer limited to linear forms. For this reason, contemporary homes tend to incorporate dramatic curves and seemingly impossible proportions.
Another main feature of many contemporary homes is eco-friendly, sustainable design and smart-home technology that reflects a response to today’s climate-change emergency. For instance, contemporary homes are often constructed of natural and recycled materials.
There are many products available in the market for contemporary façades.
• Precast concrete panels
• Natural stone/granite/tile
• Stucco
• Fibre cement panels
• Terracotta
• GRC/GFRC/FRP
One prominent solution to many of the above cladding materials is using aggregated Portland cement boards as base substrate and then jointing and
finishing substrate with a cement-bound, synthetic resin-enhanced basecoat. This basecoat provides a seamless surface for the final texture/paint/coating. This technology is used in various applications in façade like:
Exterior Drywall - Cement board is a superior alternative to traditional construction methods such as brick walls or AAC blocks. A typical exterior drywall consists of exterior grade cement board + basecoat along with interior grade Gyp boards from the internal side of a stud frame. Insulation is filled between the external and internal board cavity for various levels of fire rating and acoustic insulation.
Direct Applied Exterior Finish Systems
- DEFS are relatively new wall cladding systems utilizing polymer-based products with various sheathing boards which function as a substrate. These systems generally do not have an insulation component, although, in one case, the substrate also serves as insulation.
Exterior Insulation Finishing System
- An Exterior Insulation Finishing System (EIFS), also known as EWI (Exterior Wall Insulation System) or External Thermal Insulation Composite System (ETICS) is a type of cladding system that provides exterior walls with an insulated finished

surface & waterproofing in an integrated composite material system. Put another way, an Exterior Insulation Finishing System/External Thermal Insulation Composite System can be defined as an ideal energy-efficient thermal wrapping or façade insulation applied to the exterior surfaces of a building which is then finished with a long-life, decorative and protective wall coating that can be installed on any type of construction.
We will find many different companies worldwide offering different solutions for various façade cladding options in cement boards. Some manufacture almost all components like Cement board/insulation/ vapour barrier & finishing basecoat. Some manufacturers specialize in manufacturing independent components like substrate board/basecoat. Eventually, a façade system installer provides a final solution to clients based on site requirements. Clients will always have a wide range of products/ manufacturers to choose the required system as per their requirements.
There are various advantages of the above system:
1. Fire resistant – Almost 100% of components of DEFS are non-
combustible hence it is practically very safe to be used in façades.
2. Thermal insulation – With more and more usage of air conditioning, energy saving in buildings become very important. Various insulation methods inside DEFS/EIFS buildings can be made more energy efficient.
3. Acoustic insulation – Exterior drywalls can be used to achieve various levels of acoustic insulation
4. Design freedom – With flexible cement boards and top basecoat, practically any design/height and shape can be achieved using the DEFS system. There are many exteriorgrade textures/coatings available by many reputed brands for clients to choose from.

During the design brief meeting, the client shared his experience with Ar. Parag about challenges of Masonry construction in steel building. Ar. Parag
with his vast experience in PEB buildings found a solution for this problem by using Exterior Drywalls with Moisture barriers and avoiding joinery between Steel beams to wall partitions. Wall heights varying from 3Mtr to 5 m were another challenge for construction. MRWL team worked on various details of joints, groves, and junctions to make sure that façade looks neat and clean and is well protected against any seepage and leakage issues.
Architects also used cement boards innovatively to create contrasting bands over exterior drywalls both horizontally & vertically.
Cladding
5. Lightweight – Reducing the weight of the façade system also reduces concrete & steel consumption hence reducing overall construction cost.
6. Faster – Exterior drywalls are at least 4 times faster than conventional construction methods, hence buildings like hotels/malls/hospitals can be constructed faster to generate revenue for clients much in advance.
7. Leak-proof/mould-free surface – With top basecoat technology buildings become crackproof and leakproof hence increasing building-like and making the façade look younger for many years.
8. Better finish – As the boards are installed over blockwork using steel frames, the plum and line of the façade are very much smooth and flat as compared to RCC/ Blockwork.
9. Green construction – Construction of exterior drywall requires only 5% construction water as compared to block work. Also, cement boards are only 12mm thick which requires less energy spent during manufacturing and transportation to the site, making exterior drywalls a very good solution in green buildings.
When we came on board for this project, the application was for a simple exterior drop beam to be created at the slab edge on typical floors (23rd to 49th). During the first phase of installation, both architect and clients realised the versatility of the seamless finish achieved by DUROCK boards also reducing the total weight of the façade system. During phase 2 construction system was used to construct dummy beams and columns, projected box cladding, soffit ceiling and a grand entrance gate arch. Overall 20000Sq.Ft of cement board dry cladding was used, after painting the entire cladding just merged with exterior

India’s first premium flagship Apple store constructed is Positioned on a prominent corner of Jio World Drive, BKC. Ground + 1st floor is designed for retail space and has a huge glass façade for more visibility
and natural light. On the 2nd floor above Canopy is their office space, where, apart from the glass façade clients needed a rain screen façade system to give this façade a more settled look and feel, a
layer of insulation was added between cladding & block work for better thermal comfort for the occupants. The entire cladding was also wrapped with a TVYEK membrane to manage water ingress behind the cladding. There was also a curved wall cladding in the façade where a smooth curve was very essential to give the premium look to the façade.
This commercial building is 3rd building within the Chalet Powai hotel complex. It’s a PEB building constructed by L&T. The Architect wanted a picture frame around the glass façade, a total of 170m long cladding per floor around the glass façade and their requirement was to have this in seamless finish with texture paints. This cladding also acts like a soffit and will have very interesting façade lights post-sunset. Façade gets an unobstructed view from Powai Lake. A specially designed DEFS system along with the customised PPGI frames solution reduces cladding weight. The façade looks very natural but at the same time, it provides good protection for the structure from weathering. This is a masterpiece in making and installation will be complete by Oct 2023.
Whether you are in the process of a new construction or refurbishing an existing façade, getting the right building materials is essential. Exterior drywalls/ cladding and ceilings must be stable and durable during different weather conditions and the drywall system offers that stability. Drywall can be used for the construction of regular walls and ceilings but also as a façade cladding material. It
can be removed and installed easily and can be cut in all sizes. It is manufactured faster and this makes a difference to the energy costs during their construction. Most important is the finish one achieves with cement board cladding. Exterior drywalls are a very familiar construction technology worldwide and slowly many Indian developers are also using this world-class technology to build faster and better.

Lingel Windows’ Eco-Friendly Manufacturing Unit at Rewari, Haryana
Lingel’s giga factory located at Kapriwas in Rewari, Haryana, is nothing less than a trendsetter for upcoming industry units. What makes the manufacturing unit so special is the geographical positioning of the unit itself: its north, south, east, and west location, and its fenestration.
Since the large glazing at the production area is east and northwest-facing, there is almost no direct sunlight hitting the windows throughout the day, and heating up the fabrication facility further. But, at the same time, it gives ambient daylight to the unit, so that the production unit runs without any artificial light almost throughout the day, which saves a lot of energy. Though the south-facing area has the maximum light impact, cantilevers above the windows and the large glazing protect the glass from direct sunlight. The rooms are flooded with sunlight but without heating up the facility.
Both the production area and the offices have metal roof sheets with large insulation panels on the inner side ensuring that the heat of the metal sheets does not go through the production area and prevents the unit from heating up. At the centre of the roof of the unit, a large opening has been provided; it works as a natural ventilation system. Hot air created
inside the factory passes out and the environment, even on a hot summer day, remains pleasant inside.
With 12 metres in eight, throughout the year we have a very comfortable climate in the production area, ensuring better air exchange. In the centre of the fabrication unit is the Lingel control tower that

houses the company’s core team and the MD’s cabin; with wide views of the production activities taking place. On the 2nd floor is a viewpoint that also serves as an informal space where Lingel members and customers can enjoy the view of the windows being produced. An auditorium is also being constructed on this floor. Also planned is a glass bridge which will be 10 metres above the floor. It will serve as an entertainment factor and help one to take a look at the manufacturing process of the windows.
Since the entire set-up is 4 feet above the ground, it is easy to load and unload the incoming/outgoing Lingel’s super heavy windows onto trucks that come to the required level, also reducing manpower requirements and high costs incurred otherwise.
Lingel’s 150-metre-long fabrication unit works similar to an automotive production line. Various workstations function simultaneously and parallel to each other so that multiple windows can be produced. At the back is a storage space for incoming material, while the windows produced are stored in the front area. This planned straight production line works seamlessly from loading of materials to production to assembly to storage of ready windows to their offloading on trucks for despatch.
The factory is divided into two parts: The left wing is for aluminium production and the right-wing is for uPVC production. Since both are placed in a straight line, there is a continuous flow of profiles and finished material from the backend and frontend. This saves time, and labour, and enables quick storage.
Provision has been made for solar panels on the roofing of the production unit. The company plans to install the panels during 2024–25. There is also a rainwater harvesting program for collecting rainwater and reusing it in the landscaping and other areas of the premises.
As per the Haryana government’s safety norms, Lingel has installed fire-fighting equipment, a water storage tank of more than 200,000 litres, and three fire safety pumps, and a generator, so that in case of a fire breakout and a power failure, the fire can be doused. On the roof of the
building, another storage of 20,000 litres of water has been installed, as an extra precaution.
“One of our prime concerns when setting up the unit was that we wanted all Lingel team members to have a safe and comfortable work environment and to showcase our fabrication process in the best possible way to potential customers visiting the factory.” Mario Schmidt, Managing Director at Lingel India.

Why Ozone Glass Fittings are known as Glass Ka Better Half
Glass - one of the most versatile building materials innovated by mankind - makes the foundation of any building envelope or partition in an urban living space. The emergence of architectural processed glass requires hardware and a support system to enable its use, to enable it to stand and to move, without which its usage and existence become meaningless. This is why hardware, the glass support system, becomes its Better Half.
In India, Ozone is synonymous with the architectural glass industry as one of the most significant contributors and has helped enable glass usage
in various applications through its hardware solutions. For over 20 years, the brand has stood alongside the glass application to ensure its safe usage, promising high-quality fittings with a value of money quotient. Ozone has footprints in more than 45 countries now, moving more than a million glass doors today.
When it comes to doors, Patch Fittings are the most widely used Hardware Fitting Systems. Since the entire weight and movement of the glass depends on the hardware, these fittings must be made from high-quality raw materials to secure the door properly and avoid any untoward incidents. Ozone’s Patch
Fittings ensure that the glass is gripped to perfection with anti-skid gaskets and stainless steel screws, making it the perfect companion to glass and ensuring years of smooth operation.
The emergence of painted and printed architectural glass used in interiors paved the way for glass hardware in different finishes and colors. This led to the launch of ‘Colors by Ozone’ which complemented high-quality finishes in Gold Polish, Gold Matt, Rose Gold, and Black Matt. It brought the zing to the glass and made it the perfect partner.
Ozone ensured timely upgradation of its solutions and range to ensure continuity of the glass usage for interiors. The change of trend from frameless to frame led to the launch of the Demountable Partition Systems. This engineered system enables easy installation of partitions with minimal permanent changes making it demountable in nature. The success of the Ozone range of Hana, K-Lite, and Outliner is a testimonial to this timely addition enabling the perfect bond of glass with hardware.
Ozone Fittings has always stood hand in hand with glass; without either, the other is half, and having a full is essential.
The world is going through a time, where mankind is struggling hard to create a balance between environment & lifestyle. Our environment has reached a level where it has become mandatory for us to develop and use products that are sustainable in nature & helps in reviving the environment where our future generations can live happily.
If we see most parts of the world, infrastructural development is at pace and there is a huge scope for further development. It states that more construction and associated material are required which will harm nature if the material is not eco-friendly or nonrecyclable. In the past 100 years, we have consumed a lot of natural resources, which can not be created again.
profine Group, a German company, is a globally renowned name in the fenestration industry producing sustainable uPVC window and door systems. Sustainability has always been at the core of business strategy and the company considers this as the USP and
our contribution to nature. The brand “Koemmerling” has been in the business of PVC products since 1897, when Karl Koemmerling established the company. Over the past 60-70 years uPVC has become popular and one of the dominating materials for sustainable window and door systems, especially in the developed nations. Estimates suggest that these systems account for nearly three out of every four residential replacement windows installed in the Western world, due to their minimal maintenance, energy efficiency and durability advantages.
In the past two decades, uPVC windows have established its strong footprints in India as well, Koemmerling started its India operations in 2004 and became one of the major players in the Indian fenestration industry. It’s been a remarkable journey for uPVC in India, initially when uPVC window & door systems were introduced, people were not heard of these systems. The response was not convincing, people were hesitant due to reasons like uPVC was considered just a plastic, its structural performance was in doubt. The second reason was price & supply, as only one or two players were supplying these windows in the market. Slowly but steadily, brands like Koemmerling have been successful in creating awareness about these advanced and sustainable window and door systems.
In these two decades, if we see the growth of uPVC its been one of the major contributors to the fenestration industry. There are multiple reasons for the growth like aesthetic appeal, excellent surface finish, multiple colour options to match the interior/ exterior of any building, perfect installation with zero air and water leakage, high sound insulation, and excellent thermal insulation. Moreover, these technically advanced window and
door systems require minimal to zero maintenance over their long service life. Such appealing advantages have helped these window and door systems gain popularity and give a fresh outlook to the Indian fenestration industry.
A HOLISTIC APPROACH TOWARD SUSTAINABILITY
As a leading uPVC profile manufacturer, Koemmerling has expert knowledge of uPVC composition with the right blend of PVC, impact modifier, TiO2, processing aids, filler (CaCo3), and stabilizers. The composition of this unique formulation is 100% lead-free. Sustainability is an integral part of the brand “Koemmerling”, which takes what it calls a ‘holistic approach’. Koemmerling symbolizes the future which was, is, and will remain a key driver for innovation and material that is 100% recyclable and committed towards zero carbon footprints. Since uPVC is naturally an energy-efficient material, we make sure our product achieves optimum energy saving through advanced engineering. Multi-chambered profiles, professional fabrication, and installation leave no possibility for air leakage and with the use of special glasses, these systems help in achieving outstanding thermal insulation which further assists in energy conservation. With the increasing popularity of uPVC, the rate of cutting down forest for the fabrication of windows and doors have come down significantly. There is a huge demand for uPVC window and door systems in the replacement market.

How to choose cladding materials like laminates?
The selection of a cladding material revolves around critical factors that determine the overall success of a building façade:
1. Protection: Façades must shield the building from climatic and mechanical impacts, ensuring the space inside remains unaffected. They should also offer privacy to occupants, safeguarding them from onlookers.
2. Durability: Lasting impressions matter, and façades should maintain their appeal over time. The strength of the cladding material is crucial to
defend against fire damage, water damage, and vandalism, ensuring it withstands the test of time.
3. Sustainability: With growing environmental awareness, responsibly sourced cladding materials with minimal emissions are preferred. Exterior grade compact panels, like Greenlam Clads and NewMika FX, go beyond sustainability by providing a ventilated façade system that reduces energy consumption through improved airflow circulation.
4. Aesthetics: Design freedom and a diverse range of finishes enable the creation of unique statements or seamless blends with the surroundings, making aesthetics a top priority.
5. Considering these essential aspects, Greenlam Clads and NewMika FX are exceptional cladding solutions that excel in meeting all the above criteria and more. Their remarkable performance and sustainable features make them the ideal choice for innovative and enduring building façades.
Exterior Wall Cladding
Materials, Trends, Safety & Testing
Handa’s Farmhouse, New Delhi - Aashray Design Consultants
Exterior wall cladding is a crucial aspect of building design that offers both practical benefits and aesthetic value. It enhances a building’s appearance, protects it from the weather elements, and contributes to its overall performance and longevity. The choice of cladding material should be made based on factors such as climate, architectural style, maintenance considerations, and environmental impact. The right cladding helps to maintain the buildings weather-tight and cost-effective. It provides thermal insulation and helps in reducing the temperature variation inside the building. It also helps to improve interior acoustics and daylighting. The cladding can influence the value, saleability and safety of the building. So cladding your property effectively is a wise investment that pays both short and longer-term dividends.
Certainly, investing in new cladding for your property can be a great way to enhance its aesthetic appeal and give it a unique touch. Investing time and thought into selecting the right cladding for your property will ensure that you create a visually appealing and durable exterior that reflects your personal style. Here’s a comprehensive guide to help you get started:
Cover Story
THE PURPOSES OF EXTERIOR WALL CLADDING
External Cladding has quite a diversified usage in the building envelope. Its primary purpose is to enclose the envelope, which is weather-tight, acting as a moisture barrier and a thermal Barrier to keep the inside environment safeguarded from the extreme outside weather. From a design point of view, it reflects the design philosophy chosen by an architect, from contemporary design to classical design, the cladding is the conclusion of that, points out Ajay Gupta, Founder of Knowledge Squirrel and Co-founder of Studio Masons.
According to Ar. Amit Murao, Partner, Aashray Design Consultants, exterior wall cladding serves multiple purposes, such as enhancing the building’s aesthetics, providing weather protection, improving energy efficiency, and contributing to the structural integrity of the construction.
Ar. Ankit Garg, Founding Director, Aakrit Creative Design agrees that the main purpose of cladding is to enhance the visual appeal of a building. It comes in various sizes, shapes as well as materials, colours and textures allowing people to achieve different looks and styles to complement the overall design and character. The cladding acts as a protective barrier against the elements,
including rain, wind, snow, and UV radiation. It helps to prevent moisture penetration into the building envelope, thus reducing the risk of water damage and the generation of bacterial mould growth.
Ar. Amit Gulati, Founder Partner, Design21: The multifaceted role of exterior wall cladding extends beyond mere protection and aesthetics. It acts as an architectural element, shielding the building from external factors, including harsh weather, UV radiation, and pollutants. Beyond durability, it forges an intimate dialogue with the surroundings, elevating the structure’s visual identity and making a bold statement about its design philosophy. A harmonious blend of function and form, cladding embodies the essence of sustainable design by fortifying the building’s resilience while creating an inviting façade.
Ar. Paras Netragaonkar, Urbanist, Architect and Landscape Designer, Shilpi Architects and Planners: The choice of exterior wall cladding should strike a balance between functionality, aesthetics, sustainability, and compliance with local regulations. Exterior wall cladding serves a multifunctional role in modern building construction, combining practicality, aesthetics, and protection to enhance the building’s performance and appearance while respecting the broader context of the location and its social impact.

The main purpose of exterior wall cladding is to give character to the building and protect the exterior skin from weathering action. If exterior wall cladding is installed, the surface will have to be plastered or some kind of paint will have to be applied. The exterior wall of any building is exposed to environmental factors such as heat during summers, monsoons, and bitter cold in the north in addition to pollutants that attack the surface of the building across all seasons. In case we do not install any exterior wall cladding, the painted or plastered surface comes in contact with the pollutants that have the necessary ingredients to deteriorate the thin layer of protection.
Plaster being cementitious is bound to have surface cracks due to its inherent nature to shrink and weak in withstanding tensile forces. Pollutants enter these cracks and the process of carbonation starts destroying the plaster.
There has been a lot of research and adlibs done to improve the performance of plaster by adding fibers during the manufacturing of the plaster either in the plant or in situ that help prevent cracks. Painting on top of it helps bridge the crack as the paint has some properties of elongation but can bridge beyond a certain crack width and will tear. This situation is similar to an exterior wall having no paint, which was applied considering its ability to withstand pollutants and prevent entry of carbon dioxide (CO2) into the cracks which further reacts to form Carbolic Acid with the moisture or water available and starts the spalling process over a period leading to deboning of the plaster. If this situation is left untreated, major repairs to restore the exterior surface will have to be done. This common sight is seen in the majority of middle-income housing, old industrial structures that had only plastering and cementitious paint to protect them.
Installing exterior wall cladding helps prevent the cracks from appearing as there is some kind of uniform or constant temp that is maintained on the exterior wall surface and even if there is a wide fluctuation, due to the presence of the cladding, the variation does not reach the exterior wall, preventing the cracking and thus the carbonation from occurring.
If a dry cladding system is installed, there is a gap that is created by virtue of the system that allows air to circulate between the cladding and the exterior wall preventing wide fluctuations of temp and preventing the cracks from appearing. However, this leads to other problems of moisture getting absorbed by the exterior wall - either a brick wall or in concrete. If due to bad workmanship, there are hollow pockets in the concrete or the brick, block joints are not densely packed with mortar, water or moisture can enter these defective areas and start damaging the interior spaces.
Whenever a dry type of cladding is installed, a good variety of moisture barriers is applied on the concrete or block-plastered surface. In some rich nations that can afford it, cladding is mandatory due to climatic and codal requirements. Cladding is installing an insulation sheet on the exterior wall to prevent heat gain, impacting and increasing the heating or cooling demand, as the case may be.

BEST CLADDING SYSTEMS
The best or worst cladding systems can’t be defined easily, says Gupta. It all depends on multiple parameters. The design philosophy defines the best material. Other factors like the climatology of the region where the project is conceived, the budget and the timeline for completion, etc., will play a role in defining the right cladding. Manufactured products, such as composite panels, metal cladding, etc., do help in controlling the quality of the cladding as they come in pre-manufactured unit sizes with engineered connections & are much more forgiving in any errors that may have occurred in the base structure of the building, adds Gupta.
According to Ar. Murao, the best building cladding systems vary depending on the project’s requirements and budget. Some popular options include aluminum composite panels, fiber cement, natural stone siding, and high-quality wood laminates.
CLADDING SYSTEMS
a. Aluminium Composite Panels (ACP):
ACP consists of two thin aluminum sheets bonded to a core material, typically made of polyethylene. ACPs offer lightweight, weather resistance, and versatility in design. They are widely used in modern architecture due to their ease of installation and a broad spectrum of color and finish options.
b. Fibre Cement:
Fibre cement cladding comprises a mix of cement, cellulose fibers, and other additives. It is durable, non-combustible, and resistant to rot and pests. Fibre cement is commonly employed for both exterior and interior cladding, providing a natural and textured look to buildings.
c. Natural Stone Siding:
Natural stone siding utilizes various types of stone, such as granite, limestone, slate, or sandstone, to create visually appealing and durable façades. It offers a timeless, elegant appearance and can withstand different climates, making it suitable for a wide range of projects.
d. High-Quality Wood Laminates:
High-quality wood laminates are engineered wood products that replicate the look of natural wood. They are used as cladding to provide warmth and a contemporary touch to buildings.

The ‘best’ building cladding system can vary depending on various factors, including the specific needs of the building, desired aesthetics, budget, location, climate, maintenance considerations, and design preferences, says Ar. Garg. It is essential to adhere to local building codes and regulations when selecting a cladding system.
According to Ar. Gulati, Aluminium composite panels gracefully blend practicality with a modern touch, while wood siding exudes an organic charm that stands the test of time. For those seeking a seamless blend of sturdiness and versatility, fibre cement emerges as a distinguished contender. Stone siding provides an elegant and timeless appeal, suitable for both traditional and modern designs. Metals like zinc and copper lend a unique appeal that evolves over time.
From a durability point of view or ascetic point of view, Granite exterior wall cladding is considered the best
material, points out Balaji. The cost of such cladding is high, considering the dimensional stability requirement as per the code provision. “Normally architects and designers use Granite only to accentuate or cover up the dead walls. The majority of the walls have openings that are required to bring natural light into the building to meet certain natural light criteria and reduce artificial light. If the orientation of the building is such that the widows or openings face East and west, heat gain through the glass will be high, increasing the cooling demand in hot climates and heating loads in cold climates. thought Low E, high-performance glasses are used to control Solar gain and transmissibility, Double glazed units are commonly used to help improve the energy demands of the building”, adds Balaji.
Many other cladding systems like using High-Pressure Laminates (HPL), terracotta tiles, cementitious boards suitable for external application, and ceramic tiles stuck with adhesives are available and used. With the major fire accidents that have happened in the recent past, ACP which was seen as a cheap option to granite or other types of exterior finishes is not in vogue. Many prominent developers in India have stopped using ACP in their projects or replacing them with pure coloured Galvanised Aluminium sheets.
Pure copper sheets are not recommended as they are extremely expensive & difficult to protect from copper sulphide formation due to Ionic bond reactions.
There was a time when very good external paints with improved acrylic and silica fines were popular known as textured paints, but with the advent of glass façades, and curtain walls, even these thick exterior paints with good crack bridging properties are used only in high-end high-rise residential projects and not so much in commercial projects.
Modern materials like GRC (glassreinforced concrete), GRG (glass reinforced Gypsum), and UHPC (Ultra High-performance Concrete) which are fire resistant are becoming popular because of their versatility to take desired shapes & colours.
Fire-reinforced boards are becoming popular due to their fire-resistance property. The fibre used is Polymelamine fibres, which are non-combustible and when used with concrete become safe for use as an exterior cladding material. Materials like GRP (Glass Reinforced Plastic) must be avoided as the plastic may aid fire to propagate.
TRENDY EXTERIOR CLADDING MATERIALS AVAILABLE IN THE MARKET
Trending cladding materials include all kinds of metal and composite panels as they are a true reflection of contemporary architecture, which many architects focus on, observes Gupta. Large-scale projects also demand fully manufactured external cladding as it helps in managing and controlling the quality of the entire project.
According to Ar. Murao, innovative materials like corten steel, engineered wood, high-pressure laminates and advanced metal composites are the trendiest cladding materials for various types of projects, adding versatility and distinctiveness.
A Super luxury façade & serene landscape design, Aakrit Creative Design
Ar. Garg highly recommends modified wood products as the trendiest exterior material that is gaining popularity in the market due to their innovative designs, sustainability features and unique aesthetics, because they are thermally treated or acetylated wood, offering enhanced durability, improved resistance to decay and insects, and reduced maintenance requirement. With these properties, they retain the natural beauty of wood.
Ar. Gulati, too agrees that the popularity of engineered wood products is on the rise, owing to their sustainability and aesthetic appeal, emulating natural wood. Façades adorned with porcelain panels, featuring vibrant designs and colours, infuse a modern and artistic essence. Translucent panels that allow natural light to filter through create unique & visually striking exteriors. These trendy materials cater to modern construction trends, offering a combination of aesthetics, functionality, and sustainability.
Ar. Netragaonkar gives a list of trendy exterior cladding materials: metal cladding, wood cladding, composite cladding, stone cladding, brick cladding, nature cladding, curtain wall, etc. These materials cater to
different project requirements, budgets, and design preferences.
The trendy exterior cladding material today is Granite, fixed using a dry cladding system, says GS Balaji. The dead walls having the fire escape staircases are usually cladded with curtain walls as they would like the well-lit interior to be visible. Normally combination of many materials is used to make the building look beautiful. Balaji adds that, of late, terracotta tiles in small quantities and high-pressure Laminates that look like wood but are suitable for exterior use are being preferred.
In the high-rise residential segment, with massive use of engineered formwork and seismic design requirements to fulfill coal requirements, a considerable
amount of shear walls are incorporated in the design. These walls today can be built to very good dimensional tolerances requiring no plastering to cover workmanship defects.
If the client has a good budget, dynamic façade or cladding or popularly responsive façade can be used as exterior wall cladding. Some of the popular features in a dynamic is the use of sensors and motors that operate to cut off heat, and glare and provide shading working as an external skin responding to the demands of making the building energy-efficient.
KEY FACTORS TO CONSIDER WHILE RECOMMENDING EXTERIOR WALL CLADDING MATERIALS
Recommending exterior wall cladding can be classified into a few critical factors, points out Gupta. Design philosophy, the type of project, especially the scale of the project, the geographic location of a project, and crucial factors like time and budget influence the same. Ar. Murao adds that factors such as climatic conditions, sustainability, durability, maintenance, and compliance with local building codes play a crucial role in choosing the wall cladding.
Key factors to ensure the chosen cladding materials align with the specific requirements & goals of the project:
1. Climate and weather conditions: The local climate plays a significant role in determining the durability and performance of the cladding material.
2. Maintenance requirements: Different cladding materials have varying maintenance needs.
3. Durability, weather resistance and longevity: Choose materials with proven durability and a long lifespan. Factors such as resistance to moisture, UV radiation, pests, and physical wear and tear are essential considerations.
4. Aesthetics and architectural design: The visual appearance of the cladding material should align with the architectural style and design goals of the building.
5. Insulation and energy efficiency: Some cladding materials offer better thermal insulation properties than others.
6. Fire resistance
7. Environmental impact and sustainability
8. Cost and Budget
9. Thermal and noise insulation and energy efficiency
10. Weight and structural considerations

Ar. Gulati recommends climate suitability as the crucial factor while selecting cladding material as it should withstand the specific weather conditions of the region. Maintenance requirements play a significant role in the long-term durability and costeffectiveness of the cladding system. The environmental impact of the cladding materials is also essential in the context of sustainable and ecofriendly construction. Finally, the architectural style of the building should be considered to ensure the cladding complements the overall design vision.
According to Balaji, in addition to the above-mentioned points, the cladding materials should be chosen considering:
1. Aesthetic look and feel, which gives a character to the building or what the client and architect say, defines the building.
2. Prevent ingress of any external elements like rain, wind, extreme heat, become a house for pests, not consumed by termites, etc.
3. Durability and maintenance cost, what we call life cycle cost.
4. Ease of installation and replacement
5. Resistance to environmental harsh forces such as rains, pollutants, aging, losing the structural strength capability due to fatigue, and ability to resist and not fail under cyclonic conditions
TRENDS IN DESIGNING EXTERIOR CLADDING CONSIDERING HIGH-RISES AND LOW-RISES
High-rise and low-rise can have very different parameters to consider for the external wall cladding. In the current scenario, says Gupta. High-rises need to have factory-manufactured external cladding, which is maintainable by a Building Maintenance System installed at the rooftop for cleaning and replacing any damaged panels. On the other hand, lowrise Buildings can have a mix of all types of claddings. For example, earthy vernacular design ideas. It could be just plastered and painted or clad in wood or wood-like manufactured products. In low rise, the choices are endless.
For high-rises, curtain wall systems with energy-efficient glazing and unitized panels are gaining popularity, notes Ar. Murao. As observed by Gupta, Murao too opines that low-rises are witnessing a resurgence in natural and traditional materials such as timber cladding and stone veneers, emphasising a connection with nature and the surroundings. “In one of my recent projects, I utilised engineered wood panels to achieve a contemporary, sustainable façade design for a residential project. The engineered wood provided a warm and inviting atmosphere while ensuring long-term durability”, says Ar. Murao. The success of any cladding project relies on careful material selection, thorough installation practices, and adherence to industry standards. It’s essential to engage experienced architects, engineers, and contractors to execute these cladding solutions effectively.
Incorporating Nature into Cladding Design
Nature lovers who love doing landscape projects can go with Exterior Cladding incorporating greenery - i.e., Biophilic Design and Sustainable and Eco-friendly Materials.
• Biophilic Design: Incorporating elements of nature into the cladding design, such as green walls/moss walls or façades with patterns inspired by natural elements, fosters a sense of connection to the outdoors and promotes wellbeing.
• Sustainable and Eco-friendly Materials: There is a growing emphasis on using sustainable and eco-friendly cladding materials, such as recycled content, reclaimed wood, biobased composites, and green façades with living plants. These materials contribute to reduced environmental impact and improved energy efficiency.
These trends reflect a shift towards more sustainable, innovative, and aesthetically appealing exterior cladding designs for both high-rise and low-rise buildings.
Ar. Gulati, recommends cladding designs with unique textures, patterns, and bold colours to create visually striking façades. High-rises often prioritise lightweight materials that can be efficiently installed, while low-rises may incorporate traditional materials like brick and stone, blending classic charm with contemporary elements. Thermal Breaks, Insulated façade details and dry construction techniques are making their way into the mainstream, adds Ar. Gulati.
The perpetuation of smart cladding technologies not only checks the structure’s energy consumption but also helps improve safety, comfort & security for the residents. In façades & building envelopes for high-rise and low-rise construction, aluminium is indisputably the best material to use, associated with other materials such as glass, composite panels, glassreinforced concrete, etc., notes Ar. Netragaonkar.
Fire safety is of paramount importance in cladding design. Using materials with fire-resistant properties and adhering to fire safety regulations during installation is critical. Materials should comply with relevant fire safety standards. Ensuring that cladding materials and installation methods are fire-safe is of utmost importance for the safety of occupants and the overall integrity of the building.
Fire-safe clad is usually meant for any building above 15 meters high and that’s why manufactured metal or composite materials are the right choice today as they all follow strict standards of ASTM for fire safety that are followed globally, and hence give us some comfort having a fully enclosed fire safe building.
Several testing and certification processes can assure the fire performance of cladding systems, points out Ar. Garg. Here’s how to make sure that cladding materials & installation methods are fire-safe:
• Building Codes & Regulations: Start by understanding the local building codes and regulations about fire safety for exterior cladding.
• Fire Classification: Check the fire classification of the cladding material. Some countries have specific fire classification systems that categorise materials based on their fire performance, such as Class A, B, or C. Class A is typically the highest fire resistance rating.
• Fire-Rated Cladding Materials: Consider using fire-rated cladding materials specifically designed to offer better fire resistance.
Always prioritise safety when making decisions about exterior cladding, especially in high-rise buildings where fire safety is critical.
Architects can ensure fire safety in cladding materials and installation by taking specific measures. First, the structural members have to be fire safe ensuring the façade installations don’t compromise on that in any way, says Ar. Gulati. Further, each floor is treated as a different compartment from a fire perspective, The cladding details should help in the compartmentalisation by restricting smoke & also fire from reaching the other floors through the façade.
Architects should choose cladding materials with the correct Hour rating; Adhering to local building codes and regulations related to fire safety is essential. Architects must recommend proper installation methods to minimise the risk of fire propagation and ensure the safety of the building’s occupants and minimise the impact on the building itself. Regular inspections and maintenance of the cladding system are also crucial to identify and address any potential fire hazards promptly.
Netragaonkar concludes that fireresistant materials, such as concrete and steel, should be used in the construction. The building should be designed with fire safety in mind, including the placement of fire exits. Fire detection and suppression systems, such as smoke detectors and sprinklers, should be installed. To achieve this, several testing and certification methods can be employed to assure fire resistance. various fire testing methods are used, ranging from small-scale tests to intermediate-scale tests that evaluate the fire reaction and fire propagation.
• Testing of Cladding Systems: In addition to testing individual materials, consider fire testing of the
We have to select materials that are either fireproof, fire retardant, or avoid that aid as a catalyst to keep the fire going, releasing toxic fumes such as chlorine, and carbon monoxide which also affect humans and ultimately cause death.
In some fires, it was found that the rubber core in ACP aided the fire in travelling down the cladding when the popular belief or previous observation was fire always travelled up. In such situations, fire from either within the building travels to the exterior surface through the windows. If the cladding is made of combustible material like wood, hydrocarbon that has volatile organic compounds, or catalysts that aid the burning or accelerate the spread of fire such materials need to be avoided, rather than repenting later. There are laboratories and independent bodies such as UL, FM who test if the materials comply with and various codes that mandate a certain level of performance.
Some of the major criteria for the classification of materials for high-rise and low-rise exist in various countries and also in India. Material considered safe for use in high-rise and low-rise are categorised as Class A and Class B materials and goes up to Class F being untested material.
For low-rise buildings, which are those below 11 m in the European Union and in India it is up to 15 m, Class B materials that are fire resistant, retardant and do not contribute as fuel or become a catalyst can be used. For high-rise buildings, only Class A materials, which are not combustible are suitable. These materials must comply with Euro-class specs before they are recommended as cladding material. UPVC and wooden cladding materials must be avoided in cladding unless they are properly treated to be fire retardant and certified by independent laboratories I will add NBC guidelines for exterior wall cladding concerning BIS codes.
Aluminium, steel. stone wool (also known as rock mineral wool) and natural stone are considered to be non-combustible and preferred for cladding and insulation. Developers, consultants and engineers are familiar with the various external cladding systems that are popular in addition to glass curtain walls, glazed unitised and other types of framed panels, Metal Composite Materials (MCM) popularly known as ACP cladding, Exterior Insulation Finish Systems (EIFS). Rain Screen Systems (RCS). The most common external cladding systems used in India are glass curtain walls, Unitised glazing systems, and MCM. EIFS and RCS are not very popular either due to their poor fire resistance property and cost.
In general, all the above systems must have fire resistance as per the local requirements and codes. Materials in general, used in external cladding, need to comply with the requirements specified in
• NFPA 285 – standard fire test method for evaluation of fire propagation characteristics
• ASTM E119 – Standard test Methods for Fire Tests of Building Construction and Materials
• ASTM E 1354 -Standard Test for Heat and Visible Smoke Release for Materials and Products
• ASTM E2307 – Standard Test Method for Determining Fire Resistance of Perimeter Fire Barriers
• BS 8414 – Fire performance of External Cladding Systems
• BS 476 – Fire Tests on Building Material and Structures
• NBC 2016 – suggests installing fire sprinklers within 600 mm from the external cladding / Façade assembly in a building fully protected by sprinklers. In a building not protected with sprinklers, materials used must have fire resistance anywhere between 60 – 240 m for various components of the building.
The majority of the material used in external cladding either complies with these codal requirements or is totally inert to fire.
entire cladding system, including the assembly and installation methods.
• Fire Safety Plan: Develop a comprehensive fire safety plan for the building, including evacuation procedures, fire suppression systems, and fire drills.
CONCLUSION:
With the concept of low carbon, carbon-neutral buildings being the requirement of the day and India’s commitment to reduce factors that contribute to Global warming, materials that have low embodied energy are preferred. Though India has achieved
its renewable energy goals well ahead of 2030, we have a humongous task of achieving Carbon neutrality by 2070. With awareness coming in and newer material manufacturing processes becoming a reality, the entire construction Industry has imbibed the idea and is willing to walk the talk.

Selecting the best building cladding material involves careful consideration of several factors. The overall façade massing and the context of the building’s location play a crucial role in determining the most suitable cladding option. Sustainability is also a significant factor in making environmentally
conscious choices. Additionally, the clever combination of natural materials, such as wood, stone, and brick, can greatly enhance the visual appeal of the façade. Ultimately, the goal is to purposefully choose cladding materials that align with the design vision and contribute to the building’s aesthetics, functionality, and eco-friendliness.
Unlike high-rise residential buildings, office towers have undergone significant changes in façade cladding materials over the past decades, thanks to technological advancements. The prominent use of aluminium & glass has been instrumental in transforming building façades. Aluminum’s flexibility has allowed for the creation of intricate patterns in contemporary designs.
Smart Façades: The latest trend includes smart façades, which optimise energy consumption and provide control over interior comfort, utilising features like daylight harvesting and solar heat management.
Biophilia: Another noteworthy addition to the latest trend is biophilia, where nature is integrated into the façade design, fostering a connection with the natural environment.
The choice of cladding material & system is influenced by various factors, including:
• Scale of the Building
• Location and Context
• Local Climate Response
• Availability of Material and Labor
• Budget
• Time
• Maintenance
• Sustainability Considerations
In tropical regions, Brick, Stone, and Wood are highly recommended materials, while Laterite suits coastal areas due to its abundant availability. For faster installation in urban contexts, Office buildings extensively
use Glass and Metals like Aluminum, Steel, Zinc, and Copper.
Metal & Wood Transformation: Metal and wood materials have undergone significant transformations in recent years.
Façade Choices for High-Rise Towers: It is primarily influenced by budget, maintenance, and marketing strategy. Glass façades with a combination of metal and concrete panels are still favoured to create a perception of western skylines.
Façade Choices for Low-Rise Buildings: They use wood & stone extensively to achieve a tropical ambiance and a harmonious blend with the surroundings.
Unique External Massing: To overcome these limitations, current trends emphasise creating distinct external massing through the interplay of shadow and light. This approach adds depth and character to the building’s exterior, enhancing its overall appeal.
SAFETY MATTERS
Increased Fire Safety Awareness: Unlike in the past, people are now more conscious of fire safety in buildings.
Verification of Certifications: Many products in the market claim to have ISO certification, but there is often no verification process in place.
Stringent Rules Needed: To address fire safety concerns, the Fire and Life Safety Authority should establish strict regulations for high-rise cladding materials and installation. These rules should be incorporated into the final approval process.
External Agency Affiliation: I recommend that the Authority collaborates with an external agency to certify fire safety and assume responsibility for ensuring compliance.
Exterior Wall Cladding Systems –
An Overview
Cladding acts like the skin of the built form and is an integral part of the building. Innovative cladding designs can add more aesthetics to the building and can add more value to the character of the building.
Most of us see cladding systems as a means to provide an architectural expression with a high-impact aesthetic layer to the building. We often delve with parametric techniques to design the geometric system for cladding followed by play of materials and colours, says Ar. Sushant Verma, Founder, rat[LAB] Studio.
Exterior wall cladding serves several important purposes in the construction & design of buildings. Cladding enhances the visual appearance of a building and contributes to its overall design and architectural style. It provides a protective barrier against the elements, such as rain, wind, snow, and sunlight. Cladding protects the underlying structure from wear and tear, increasing the building’s lifespan and reducing maintenance requirements. Some cladding materials offer improved fire resistance, which can enhance the overall safety of the building and its occupants, points out Sumit Sahay, General Manager, VM Zinc.

Verma agrees that the purpose of exterior wall cladding is to protect the building against weather elements. It also serves as an insulating layer, improving energy efficiency and thermal comfort. Cladding enhances the building’s aesthetics, acting as the outer skin and contributing to its architectural expression. Additionally, cladding can offer sound insulation, fire resistance, and durability, ensuring the longevity of the structure, adds Verma.
Cladding is when materials are applied on top of others, in layers, on the exterior of a building and it is designed to improve thermal insulation, weather resistance, and appearance, amongst many other benefits. Cladding is often assembled in panels. These component panels are attached to the structural frame of your main building and can be developed bespoke or installed ‘off the shelf’ to fit, says Ar. Niket Sunil Upase, Founder Architect, Ahamasmi Architect. Some cladding systems include panels and fastenings, while others feature windows, doors, gutters, roof lights and vents. It improves the interior environment quality of the space and acts to control the heat coefficient ratio and thermal mass. With the right cladding, we can improve the building depreciation due to UV rays, climatic moisture, and other climatological factors, adds Upase.
According to Ar. P S Vigneswar, Principal Architect, Architecture + Value, cladding is an adaptable and
affordable answer for aesthetics that also works as an exterior skin to resist external agents, thus increasing the all-inclusive durability of the building. Utilising appropriate cladding material wherever it is needed is a crucial point that should not be overlooked. In the building industry cladding is a boon to many who invent, create and experiment with designs. For designers, it can be an identity of their creations.
Ar. Priyanka Arjun, Head Architect, Priyanka Arjun and Associates lists the key benefits of cladding:
• Insulation: Enhances thermal
performance by adding an extra insulation layer.
• Beautification: Offers varied designs, textures, and colours for improved aesthetics.
• Faster renovation process: Enables swift installation compared to other methods.
• Durability and longevity: Increases building lifespan by safeguarding against wear and tear, reducing maintenance costs.
• Ease of maintenance: Reduces environmental exposure, leading to fewer repairs and lower maintenance expenses.

WHAT ARE THE BEST BUILDING CLADDING SYSTEMS?
Timber is still one of the most aesthetically attractive cladding materials, says Upase. Timber cladding is often put in long, narrow boards laid horizontally, vertically, or diagonally. The finished product can be completely customized to create the aesthetic look you like. Bringing natural beauty, warmth, and sustainability, wood cladding enhances a building’s appeal while delivering functional advantages for both exteriors and interiors.
Natural stone provides buildings with a luxurious and timeless aesthetic, offering various stone types for diverse aesthetic choices. Stone cladding is more often found in residential homes than in commercial ones. Stone is ideal for giving homes an attractive, opulent appearance while maintaining a classic “country home” atmosphere.
Metal cladding is a method of protecting one metal (or composite) by forming a layer of a second metal on its surface by using techniques such as diffusion, deformation and lasers. Metal cladding is also used on the outer surfaces of structures as well as buildings for corrosion and abrasion protection.
Fibre cement cladding: Fibre cement is made from sand, cement and cellulose fibres. Fibre cement cladding is a popular choice for builders because it is simple to install, weatherproof, and resistant to water.
Vinyl cladding is perfect for people seeking a contemporary, modern material that comes in various colours. Because vinyl is still one of the least expensive cladding materials and has demonstrated energy efficiency. It is cost-effective during the installation process and in the future. Panels can even be installed with an extra layer of insulation, forming a temperature-controlling blanket over your property, keeping it warm in the winter and cool in the summer.
Zinc cladding is a type of metal cladding. It comes in many different forms and sheets can be formed into shingles, cassette panels and flat-lock panels to suit any type of building. Zinc is sometimes chemically treated to slightly alter its naturally shiny finish. These treatments are usually designed to weather it quickly, giving it a patina that would take between three and 10 years to develop naturally.
Zinc is also sometimes combined with small amounts of other alloys, such as titanium and copper, to increase its malleability, durability, and corrosion resistance.
Featuring a natural patina that evolves, zinc offers an appealing, distinctive building appearance. Its durability, corrosion resistance, and extended lifespan make it an excellent choice.
Copper cladding involves covering with copper sheets or panels, offering a striking appearance that evolves. Copper has been a favoured cladding material for centuries due to its unique characteristics.
Stucco wall - Stucco is a cement-type mixture made of Portland cement, lime, sand and water. It is a thin finish coat that goes on the outermost layer of residential and commercial constructions. Modern stucco has polymers and other agents for increased flexibility that improves its resilience. Stucco is very durable.
Bricks cladding, also called “Face Bricks”, can be specified in a large number of colours and textures, and their summation and variation –thanks to their different shapes and sizes – they can create façades of great complexity and beauty. A perennial favorite, traditional brick cladding boasts classic looks and enduring strength, often applied as a veneer over other materials.

CLADDING MATERIALS AND SYSTEMS IN VOGUE
One of the most versatile types of material with an ample amount of possibilities is ACP sheets, notes Vigneswar. “It is affordable, has great insulation properties, and adequate permanence, installation, and maintenance are hassle-free. With the potential of CNC cutting, the designers have made use of a maximum of the material”, he says. While all-natural cladding materials like stone and wood have their own benefits of resistance and durability and for sure unique appearance, the alternative of artificial material has also its own gains as it can be modified accordingly.
The “best” building cladding system depends on various factors, including the specific project requirements, budget, design considerations, local climate, and building regulations, says Sahay. Different cladding systems offer unique advantages and disadvantages.
In today’s modern and parametric architecture, metal cladding has an edge over other cladding materials for the following reasons:
• Contemporary aesthetics
• Design flexibility
• Sustainability and recyclability
• Durability and low maintenance
• Versatility with other materials

• Ease of installation
The best building cladding systems depend on the project’s specific
requirements and design intent. Popular options include aluminium composite panels for their lightweight and versatility, fiber cement for their durability, wood siding for a natural look, and stone siding for a timeless and robust appearance. Zinc and copper offer unique patina effects, while brick provides a classic & enduring façade. Each cladding system has its merits in terms of aesthetics, performance, and maintenance, making careful selection crucial for successful outcomes. “With the current set of projects, we work a lot with mild steel sections (for curvilinear profiles & lower costs) as well as aluminium profiles and ACP as it can be CNC routed to create different shapes and sizes, adds Verma.
For more than a decade, glass, stone, wood, and metal/ACP have always been the traditional choice of material for exterior cladding. Nowadays, new and innovative materials such as exterior grade laminates (as per EN438-6), glass fibre reinforced concrete, and metal cladding (zinc, copper, and steel) are creating a healthy disruption in the market. The differentiating advantages of exterior grade laminates are their Eco-friendliness, thermal efficiency, energy renewability and sustainability, points out Upase.
The use of various materials other than traditional materials use as steel or even tensile fabrics has also ventured into the market, notes Vigneswar. The commercial and hospitality genre has shown the trend of the ever-changing skin of the building. He too is in favour of materials such as tensile fabric, and CNC-cut ACP screen walls as exterior wall skin to create dynamic shadow and light effects that act as a curtain from external elements.
Ar. Priyanka Arjun adds Corten Steel Cladding as one of the favourites since this weathering steel develops a distinctive rust-like patina over time, enhancing its allure in contemporary designs. Its durability, weather resistance, and low maintenance make it ideal for various climates, ensuring long-lasting structural integrity. She adds that Zinc, as an excellent material, offers exceptional durability, resistance to corrosion and weathering, and UV radiation. Its lightweight nature facilitates cost-effective transportation and installation, while its malleability allows for intricate and creative designs.
A trending approach in parametric designs, brick cladding enables diverse forms and patterns, adding a rustic and homely character to the space. These cladding options not only enhance a property’s visual appeal but also exemplify sustainable and contemporary design principles.
Engineered wood laminates provide a sustainable and visually appealing option. High-tech materials like translucent polycarbonate panels and 3D printed cladding are gaining popularity for their innovative designs, adds Verma. Ventilated façades using terracotta or ceramic tiles present a stylish choice. The market offers a broad spectrum of cladding materials catering to diverse architectural styles and preferences.

Here are some cladding materials that are trending:
• Single skin metal cladding: Various metal cladding like copper, zinc, titanium, corten steel, solid aluminium, PVD, and stainless steel metal claddings are being used in India
• Metal perforated screens/mesh panels: customised perforated screens/ metal mesh screens or panels, made from materials like zinc, aluminium, or stainless steel
Remember that trendy materials may suit some projects and architectural styles better than others. When choosing an exterior cladding material, it’s essential to consider factors such as design intent, climate, maintenance requirements and the expected life of the building.
(Sumit Sahay, Designation - General Manager , VM Zinc)
SELECTION OF CLADDING MATERIALS
The selection of materials after understanding the material and how it will be affected if used at a specified site should be the main factor. The material’s contradictory disposition can sometimes be a highlighting feature if used correctly.
When recommending exterior wall cladding materials for a specific project, several key factors should be taken into consideration to ensure the best fit for the building’s requirements and the client’s preferences. Here are the key factors to consider:
• Aesthetics, architectural style and design intent
• Durability and maintenance
• Climate, weather conditions and exposure
• Cost and budget
• Buildability, Shape and Size
• Compatibility with the building’s structural system
• Environmental impact
• Sustainability
• Energy efficiency
• Insulation and acoustics
• Fire resistance and safety
By carefully considering these factors and conducting a thorough analysis of the project’s needs, one can recommend exterior wall cladding materials that not only enhance the building’s appearance but also provide long-lasting performance and value.
CLADDING MATERIALS FOR HIGHRISES AND LOW-RISES
Material specifications like weight, durability, porosity and other factors are major factors along with the fixing of the materials. Unlike low-rise buildings, the high-rise has certain hurdles when it comes to fixing materials and the load of material has to be calculated to withstand the other influences, points out Vigneswar. The use of metals, glass and concrete are the practical alternatives for high-rise but other materials used in appropriate proportions can also be a design solution.
Cladding Material Choices
For High-Rise Buildings:
1. Glass: Modern and transparent, allowing ample natural light. Often combined with other materials for a sleek look.
2. Metal Panels: Lightweight and versatile, available in various shapes and finishes, offering a modern and industrial appearance.
It’s crucial to consider local building regulations and codes, as some cladding materials may have specific fire safety requirements. Consultation with professionals in architecture, engineering, and construction is essential.
For Low-Rise Buildings:
1. Wood Cladding: Provides a natural and traditional look, available in various wood species. Regular maintenance is required for weathering and pest protection.
2. Brick: One of the oldest and most durable materials, offering a classic and timeless appearance with a range of sizes, colours and textures.
3. Stone: Granite, limestone, and slate present a luxurious and elegant exterior, lending buildings a sturdy and enduring impression.

The following are some of the latest trends in designing exterior cladding for high-rise and low-rise buildings.
High-Rise Buildings:
Glass and Steel Combinations: High-rise buildings often feature a sleek and modern aesthetic, with extensive use of glass and steel. Large curtain walls made of glass provide transparency, natural light, and panoramic views while steel elements offer structural support and add a touch of sophistication.
Dynamic Façades: Architects are increasingly experimenting with dynamic Façades that can change shape or appearance. This can be achieved through movable panels, kinetic elements, or digitally controlled shading devices. These Façades create an everchanging look for the building and respond to environmental conditions.
Green Façades: Sustainable design is gaining prominence, and green facades featuring climbing plants or vertical gardens are becoming more popular. These living Façades not only add visual appeal but also provide insulation, improve air quality, and contribute to the building’s environmental performance.
Mix of Materials: High-rises often incorporate a mix of cladding materials to add visual interest and texture. Combining materials like glass, metal, stone, and concrete can create a harmonious yet captivating Façades.
Parametric Design: Parametric design uses algorithms to generate complex and innovative geometries. This approach allows for intricate and unique cladding patterns that cater to the specific needs of the building and its surroundings.
Low-Rise Buildings:
Natural and Sustainable Materials: Low-rise buildings often embrace a connection with nature and sustainable living. Consequently, materials like wood, bamboo, terracotta, and rammed earth are gaining popularity for their eco-friendly appeal and warm aesthetics.
Artisanal Cladding: There is a growing interest in artisanal and handcrafted cladding materials that add a sense of uniqueness and craftsmanship to low-rise buildings. This includes materials like handmade tiles, textured clay panels, and bespoke stonework.
Brickwork Innovations: Traditional brick cladding is being reimagined with innovative patterns, colors, and textures. Feature walls or playful arrangements of bricks are used to create focal points on the façade.
Sculptural Facades: Some low-rise buildings feature sculptural elements as part of their cladding design. These artistic features add character and make the building stand out in its context.
(Sumit Sahay, Designation - General Manager , VM Zinc)
For high-rises, lightweight and efficient cladding systems are preferred to reduce the building’s overall load and ensure structural stability. Modern trends emphasise sleek designs, using materials
like glass, aluminium, and composite panels to create a contemporary and dynamic appearance. In contrast, lowrises often incorporate natural materials like wood or stone to harmonize with the surroundings and offer a more grounded and inviting aesthetic. Both high-rises and low-rises prioritize sustainability, employing green technologies and responsive facades to enhance energy performance, concludes Verma.
FIRE-SAFE CLADDING
All cladding materials have different compositions which can affect the heatconducting properties, that will directly

Large curtain walls made of glass
affect the immediate structure. For example, though aluminium composite material is lightweight, durable and easy to install, it’s the least safe when it comes to fire, states Vigneswar.
Ar. Priyanka adds that fire seals are vital elements in cladding systems, placed around openings like windows and doors. Made from fire-resistant materials like fire-rated silicone, intumescent strips, or fire-resistant mineral wool, they seal off gaps and joints during fires.
To ensure proper fire safety, adherence to local building codes and consulting fire safety professionals are essential. Fire-resistant cladding materials and well-designed fire seals protect lives and property during fire incidents, notes Ar. Priyanka.
Fire safety assurance for cladding systems involves:
• Fire Testing: Materials undergo rigorous tests to assess their behavior in fire conditions, including reaction, smoke production, heat release rate, and flame spread.
• Fire Resistance Rating: Some jurisdictions require specific fire resistance ratings, indicating the cladding system’s ability to withstand fire for a defined period.
• Compliance with Building Codes and Standards: Cladding systems must adhere to local regulations,
with specific requirements based on building height, occupancy, and location.
Ensuring that cladding materials and installation methods are fire-safe is of paramount importance in building design and construction. Sahay lists the steps that can be taken to achieve fire safety in cladding:
• Fire Testing and Certification: Cladding materials can undergo fire testing to assess their fire-resistant properties. There are various fire test standards depending on the country and region, such as ASTM E84, BS 476, EN 13501, and NFPA 285. These tests evaluate factors like flame spread, heat release rate, smoke production, and combustibility.
• Third-Party Certification: Look for cladding materials that have been independently tested and certified by reputable third-party organizations.
• Fire-Resistant Cladding Materials: Choose cladding materials that are inherently fire-resistant. Materials like metal Zinc, copper, fiber cement, and certain types of stone have good fire-resistant properties.
Verma advises to choose fire-resistant materials like non-combustible metal panels or fibre cement, to minimise the risk of fire spread. Verify that the cladding meets relevant building codes and
standards for fire resistance. Additionally, use fire-resistant insulation materials and incorporate fire-stopping measures at joints and penetrations. Look for thirdparty certifications, such as ASTM E84 or EN 13501, which indicate the material’s fire performance. Engage experienced installers who follow proper fire-safe installation practices to maintain the façade’s integrity.
CONCLUSION
Exterior wall cladding is an essential component in the construction of modern buildings and structures. It enhances the building’s aesthetic look and increases the durability of its exterior. External wall cladding provides long-term protection for your building against all environmental factors and pollutants, without compromising on the beauty & designs. It also improves the property’s structural strength and resilience to abrasion, fractures, and scratches. The cladding is put in place using techniques that create a barrier between the exterior walls and the environment. This includes installing an air gap between the cladding and the walls to allow for proper ventilation that maintains a favorable temperature inside while also preventing moisture build-up. The cladding material selection among different options is a crucial issue affected by quality and cost. The implementation of the value engineering (VE) process is challenging. This edition’s cover story proposes a framework for the selection of efficient cladding materials and integrating them with the design of the façade.

Face to Face
Tell us about your educational background and career experiences. How did you enter this profession?
I studied architecture and moved into sustainability immediately after. I did my masters in sustainable design from Edinburgh, UK. On the completion of my M.Sc., I worked in London for about six years in a consultancy firm called BDSP Partnership, which specialised in sustainable design of buildings.
I moved to India to work on a project that was very close to my heart, which I felt very passionate about. It was all about creating a larger impact by integrating a set of policies that will have a larger impact on our building industry. In 2008, we started working with the Hyderabad Metropolitan Development Authority and The Energy and Resources Institute (TERI) to develop the Environmental Building Initiative for the city of Hyderabad. This was the first of its kind in India. We not only developed a whole set of guidelines for sustainable building design for different types of buildings, commercial, residential, retrofits, etc. but also organised several stakeholder meetings and created a roadmap for implementation. We also devised a set of incentives and potential regulations for increasing buyin. During this time, I got introduced to Infosys and the Manipal group and started working more in the consultancy sector. Since then, I have been working on several projects across the board as a sustainability consultant with a primary focus on high-performance buildings, specifically working with architects through data-driven analysis to help them make design decisions from very early to detailed design stages.
What inspired you to pursue a career in sustainability after doing architecture?
I’ve always been interested in the environment and conservation right from the time I was a child. Architecture happened by chance. Sustainabilityis something that I have always been interested in. If I hadn’t done architecture, I would have pursued sustainability and environmental conservation in another form.
What were the turning points in your career?
I would say, my first turning point happened when I started working for
a consultancy in London called BDSP, which specialised in high-performance building design, where they looked at buildings from a design perspective. Integrating passive design into buildings is the first step towards sustainable or Net Zero design. This was a very important part of our philosophy at BDSP. It was a huge learning experience that laid a solid foundation for my thoughts and ideals.
The second turning point happened when we started working with TERI, Ms Mili Majumdar, and Hyderabad Metropolitan Development Authorities on environmental building guidelines and regulations. The third turning point was the introduction to Infosys and Mr Rohan Parikh. Infosys then introduced me to Manipal, Group - Mr. Abhay Jain and Mr. Mohandas Pai. These are some of the key people who encouraged me and asked me to push the boundaries of sustainable design. Everything in my profession has grown organically from those turning points, with the steadfast support from my husband and family.

Could you please throw some light on the Net-Zero projects done by your firm Terra Viridis?
For a long time, India’s focus has been on rating systems regarding sustainable design, which was a good starting point because that gave a comprehensive approach to sustainability. However, the effectiveness of applying a rating system completely depends upon how closely the intent of the rating system is followed.
Over the past five years, there has been a movement accelerated by Covid, where large corporates and developers have started looking at sustainability from an operational performance perspective, focusing on resource efficiency, comfort, wellness and health, with requirements beyond rating systems. As a practice, we have come a long way in the last 15 years. By focusing on assisting the design team in achieving high-performance and highcomfort buildings through passive design integration, we now have enough case studies to showcase our philosophy that good architectural design is a precursor to high performance and that it does not cost more.
Over the past 4 to 5 years, we have moved on to working on more net zero projects with a focus on net zero energy, net zero water and net zero carbon. One of our first Net Zero Buildings at Manipal University Jaipur is one of the world’s
largest that has shown Net Zero energy in operation with 100% onsite renewable energy. Now, while we continue to focus on net zero and high comfort, wherever possible, we are looking at restorative and regenerative designs. For restorative design, we consider restoring the site’s biodiversity and making it intrinsic to the sustainable development of the built environment.
In this process, we also focus on net zero water and waste, especially in the Indian context, where we must look beyond “Reduce, Reuse, Recycle”. We work on introducing design features and spaces that help influence people to avoid waste generation, give opportunities to repair and upcycle, and help convert waste to wealth. So, this is what we have been working towards with a lot of clients, especially in universities and large campuses.
In major cities of India, there are many historical buildings. Is it possible to restore and reuse them?
It’s always better to restore and adapt a building to present-day requirements than to demolish and build from a sustainability perspective. They are also great case studies to help us understand the bioclimatic design principles of any specific location. While it requires a lot more effort and time to do so in a culturally, functionally and appropriate way, many architects are doing a wonderful job of restoring and repurposing historic buildings.
Please tell us about your organisation Terra Viridis, its growth, and its strength. What is the what does the Terra Viridis – the name of the firm mean?
Terra Viridis translates to “Green Earth” in Latin. My husband, Aditya and I started the firm in 2007 and since then, we have grown very organically, primarily through word-of-mouth references. We have been very lucky to have started our work with clients who kept pushing boundaries to achieve the best performance possible. Presently we have offices in Hyderabad and Bangalore. We also have a sister company called Vera Tatva Engineering Consultants with our MEP partners who focus on high-performance MEP design, commissioning and auditing. Between us, we provide integrated sustainability and MEP services from the early design stage to commissioning and post-occupancy
Manipal University Jaipur Admin Block - Sundaram Architects
auditing. With this, we can take our learnings from post-occupancy auditing for comfort, usable daylight, glare-related issues, thermal comfort, HVAC-, electrical, occupant behavior, etc back into design.
According to you, considering a design, what is actual sustainability for you?
Every built environment has an environmental footprint. Hence, actual sustainability is when we look at development holistically and try to reach a state of regenerative development. To achieve this, the first port of call should be to understand the carrying capacity of a site based on the function of a proposed development. If all decisions start there, starting with the quantity of built-up area, leading to resource management within what is available on site, it would be the ideal development from a sustainability perspective.
However, this is highly unlikely in India’s present development context. So, the next best thing would be to optimise the available resources (energy, water, materials) to the maximum extent possible given the function and density of the development (not limiting to what
a code or a rating system might require), future proof design for climate resilience & flexibility and minimize its impact on external services (waste and stormwater). In doing so, keeping it simple based on the user’s ability to manage would be critical as well.
It’s a myth that sustainable design or high-efficiency design is expensive. We have done detailed cost-benefit analysis on many of our projects, and the data proves that capex does not increase if the design team works together. Integrating principles of passive design in architecture to reduce demand, followed by optimising/right-sizing of the M&E systems, and integrating high-efficiency systems + controls usually has a minimal impact on CAPEX but has the ability to save on OPEX immensely.

As a sustainability consultant, where does your intervention in a project start? Towards the last stages of the project or from the design stage itself?
Earlier, sustainability consultants were involved towards the end of the project. But now, the market has matured, and we work with clients and architects who appreciate that our role starts from the very early stages of design. So we work on projects with the whole design team, integrating various aspects like conservation of resources, resilience, energy efficiency, etc., from a very early design stage onwards.
How do you think the façade will help in making the building sustainable as well as long-lasting?
After we close the initial massing, orientation, form and layout of the building, the facade is the biggest element that greatly impacts energy efficiency and comfort in any building. In tight sites, the façade ends up being the only part of a building through which energy efficiency and comfort can be maximised through architectural design. Also getting the facade right defines how comfortable the building is - both thermally and visually.
We have recently worked on developing ISHRAE’s building envelope guidelines to
define the various energy and comfort parameters a building envelope has and their effects on the building’s performance.
What is your view on using glass on building facades, considering Indian climatic and weather conditions?
Glass is not bad, it is very useful and probably one of the greatest inventions of mankind. However, it has to be used judiciously, in the right location and quantity, with the right amount of external shading, control on glare, heat, sound, etc.
Can you please tell us about some of the innovative technologies which you recommended for making buildings more sustainable?
I would always focus on design first and technology later. In our experience, integrating the right passive design techniques with a focus on comfort could have as much as 50% impact on the energy efficiency of a building. So, I would start with form, orientation, and microclimate first, then interior layouts, and then the facades. Once you get these right - technology can help enhance efficiency and comfort to achieve the best possible outcome.
Different types of innovative shading devices, be it static or dynamic, are
very important technologies for our climatic conditions, followed by spectrally selective glazing. The various types of static and dynamic shading devices available now could give the architect many opportunities to create some very interesting facades.
In almost all climatic conditions in India, there is a certain time of the year when you do not need active cooling or heating. Taking advantage of this in our buildings would have a major impact on achieving India’s net zero energy goals. The control technology that helps in seamlessly moving building operations from natural ventilation to an active cooling mode and vice versa is an area with lots of innovative solutions.
New technologies in the space of personal comfort systems and AI-based energy and water monitoring devices that provide information and control to users have huge opportunities for growth.
There have been some very promising developments ienergy low-energy active cooling technology space for residential and small building applications through the Global Cooling Prize that are worth lookout for in the near future.

We have been helping architects design facades that provide glare-free spaces with zero blinds for several offices (specifically Infosys) and university buildings, including Manipal University campuses and Ashoka University. We are working with Ar. Ashok Lall on the Net Zero TSREDCO building in Hyderabad where we are integrating innovative dynamic shading devices that are mechanically controlled seasonally.
Another aspect of design we focus on is minimising energy waste due to human behaviour. In academic institutions, especially hostels, opening windows while the air-conditioning is on is common. To
overcome this, providing limit switches not only helps reduce waste but also encourages users to be aware.
Face to Face
Tell us about some of the most challenging projects which you have worked on.
We are fortunate to work with clients and architects who give us challenging projects and demand that their projects set new benchmarks in sustainable design. Thus, every project is about pushing the envelope regarding sustainability and keeping it within budget. Probably one of the most challenging projects that we are working on right now is the National
Ashoka University, Sonipat – Perkins Eastman and Edifice Consultants
Manipal School of Architecture and Planning (the Purple Ink Studio)
Face to Face
Maritime Heritage Centre, designed by Architect Hafeez Contractor (Karl Wadia and Apoorva Sharma). It is located in a very challenging climatic condition, on a very challenging site, and the timelines of the project are tight. We are honored to say that PM Shri Narendra Modi has taken a personal interest in its evolution. Conceived as a Net Zero Energy and Water development, with the ability to adapt to a 100-year climate resilience risk, the design team is working tirelessly to achieve these goals.
Post Covid, did you see any changes in the design pattern?
Yes, people have been looking at sustainability in a completely new light. They are a lot more receptive to the idea of integrating natural ventilation and mixed-mode strategies. Previously it was very common to have sealed windows, install a VRV or a split air conditioning,
and not consider the requirement for fresh air in buildings. Now, it is much easier to convince clients to give equal importance to fresh air, and operable windows for natural ventilation/mixed-
mode operations. So, the conversation regarding indoor air quality has been pushed to the foreground.
What is your advice to young designers and young sustainability consultants?
This is what I tell all my students and anyone who works with me. As an architect, many analysis software and tools are available when you get into sustainable design. My first advice is not to jump into the simulation tools. Understand the theory and the basics of passive design first and then use the tools to test your options.
If you use tools without background theory & knowledge, you will lose your ability to find and analyse mistakes.
My second piece of advice is to ask yourself the question -Do you want to be an architect? Or do you want to be an analyst? Choose your path judiciously after understanding where your interest and skillset lies.

TCS Pune – Edifice Consultants
Could you please tell us about some of the tools, which you are using for creating sustainable buildings or sustainable developments?
We use different types of tools at different stages of design. At a very early design stage, we use many in-house developed tools. Afterwards, we use the latest parametric design tools for detailed design.
We keep up to date with all the latest software and continually explore new ways to analyse building design. Due to the complexity of our models and the need to work in tandem with the architects. We have now moved to cloud computing to run our simulations. Hiring supercomputers to run the simulations helps us get quicker results and allows the design team to experiment with multiple design iterations. Our clients expect us to push the boundaries of sustainable design expediently; thus, we primarily use cloud computing.
What is your vision for 2030 when you look at building sustainability and the entire urban development?
I hope that all the talk we have now, in terms of sustainable development becomes mainstream, with every building designed to achieve its utmost potential concerning sustainability. I hope a holistic approach to sustainable design becomes one of the major drivers in the decision-
making process of new buildings or retrofits.
I hope urban planning is based strongly on designing for climate change, both mitigation and adaptation. I hope the density of development allowed is based on the area’s carrying capacity concerning water.
I hope urban development is undertaken with utmost sensitivity to biodiversity conservation and local geology. I strongly believe that one tree saved is several lives saved.
We also have no choice but to do so. So the quicker we fall in line, the greater our chances for survival.

Navi Mumbai airport set to take flight in August 2024
Deputy Chief Minister of Maharashtra, Devendra Fadnavis, recently announced that the Navi Mumbai International Airport is on track to become operational in August 2024. The project, managed by the Adani Group, began construction in 2022 and is expected to be completed by December 2024. The airport’s development is divided into four phases to accommodate its massive scale.
This state-of-the-art airport, strategically located in Ulwe, Navi Mumbai, is envisioned to handle an astonishing 90 million passengers by 2032. It’s designed as a multi-modal facility to seamlessly integrate with various transportation systems, including the Mumbai Trans Harbour Link, coastal road, and metro network. This integrated approach aims to provide efficient connectivity for travellers.
The airport’s design is a visual marvel, taking inspiration from India’s national flower, the Lotus. Designed by Zaha Hadid Architects, it will feature three interconnected terminal buildings, all adopting the Lotus-shaped theme.
The Navi Mumbai International Airport, a greenfield project built by CIDCO, covers 1,160 hectares and is estimated to cost
16,700 crores. It’s expected to create over 4 lakh job opportunities, further contributing to the region’s development.
In addition to the Navi Mumbai project, the government is investing in a new Rs 650 crore terminal building at Shirdi airport, enhancing air connectivity and infrastructure across the state.
This ambitious airport venture, approved in 2008, operates under a public-private partnership agreement and will unfold in four phases until 2032. Despite initial delays attributed to various factors, including the COVID-19 pandemic and land acquisition challenges, the project is now on track to meet its December 2024 deadline, with Prime Minister Narendra Modi having laid the foundation stone in 2018.
Surat Diamond Bourse overtakes Pentagon as world’s largest office building
In a monumental achievement, India has unveiled the Surat Diamond Bourse, now officially recognized as the world’s largest office building, surpassing even the iconic Pentagon in the United States. This 15-story architectural marvel, boasting over 7.1 million square feet of floor space, stands as a testament to India’s growing prominence in the global business arena.
Located in the sprawling DREAM (Diamond Research and Mercantile) city, this magnificent complex comes with a staggering price tag of Rs 3,200 crore. Designed by the renowned Delhibased architecture firm, Morphogenesis, which has also lent its creative touch to projects like the BSE Tower in GIFT City, Gandhinagar, and the Zydus Corporate Park in Ahmedabad, the Surat Diamond
Bourse is set to redefine the diamond trading landscape.
Comprising nine towers, each with ground plus 15 floors, this remarkable hub will accommodate over 4,200 offices ranging from 300 square feet to a spacious 7,500 square feet. It is poised to become a bustling “one-stop destination” for the 65,000-strong diamond industry professionals, including cutters, polishers, and traders.
The Surat Diamond Bourse is not just about size; it also offers functionality and luxury. With its light-filled atriums, marble floors, and more than 4,700 office spaces, it seamlessly integrates work and craftsmanship, allowing small workshops for diamond cutting and polishing. Additionally, the facility boasts
131 elevators and a range of amenities, including dining, retail, wellness, and conference facilities.
After four years of construction, two of which were impacted by Covid-related delays, the project is set to welcome its first occupants in November. Indian Prime Minister Narendra Modi, a native of Gujarat, where the bourse is located, is expected to officially inaugurate this remarkable achievement later this year.
Kerala forges ahead as India’s first state with innovative design policy
In a groundbreaking move, the southern Indian state of Kerala is poised to establish itself as a pioneer in the realm of design policy, becoming the first state in India to do so. This initiative dubbed the ‘Design by Future’ policy, is set to elevate the aesthetics of government structures to international standards, kickstarting with the Departments of Public Works and Tourism.
Under the visionary leadership of Kerala’s Public Works Department, this policy is geared towards a holistic transformation of the state, with an emphasis on crafting distinctive design identities for government edifices. Furthermore, this policy extends its reach to private individuals, guiding them in the pursuit of thoughtful and visionary designs. At its core, the ‘Design by Future’ policy underscores the imperative to harmonize constructions with the region’s unique climate and safeguard its cultural heritage. This policy crystallized following a design
workshop held in Kovalam earlier this year, bringing together experts in the field.
The policy is currently awaiting approval from the finance department before it advances to the state cabinet for deliberation. Once implemented, it will encompass a broad spectrum of construction projects, including roads, government buildings, bridges, and tourist hubs. Each endeavour will be meticulously tailored to the distinct characteristics of its locale, seamlessly integrating the environment, community, structures, and institutions to create cohesive and aesthetically pleasing architectural marvels. Kerala’s overarching goal is not only to ensure that these constructions seamlessly blend with the local landscape but also to catalyse the state’s burgeoning tourism sector, contributing to its economic growth.
Public Works Minister PA Muhamed Riyas expressed his optimism, stating,
“Kerala will become a pioneer in this regard, being the first state in India to implement such a comprehensive design policy. Various departments have already contributed their ideas, which will be incorporated into the final version before it goes for cabinet approval”.
