EDITOR’S NOTE The Indian fenestration industry has undergone many changes in terms of engineering and material usage over the years. Window and door manufacturers, suppliers and dealers use a variety of energy-efficient technologies, methods and products for their projects in order to bring in more sustainability. The fundamental goal of the fenestration is to develop a climate control system that enables individuals to significantly improve the energy efficiency of their home or office building. This solution incorporates control over both light and heat entering the room by optimizing room fenestration. The September/October issue of Window and Facade magazine is exploring this topic and how it relates to the fenestration industry. Creating a building that is not only beautiful and comfortable, but also highly efficient requires a design approach that considers the entire building – that is the indoor climate controls and the building envelope as a single, integrated system. Unsurpassed thermal performance is another key aspect to consider while providing fenestration solutions. Novel fenestration systems offer the freedom to create building envelopes with large window-to-wall ratios that minimize energy loss while enhancing security, moisture and acoustic control. Whether it is an energy retrofit of an existing building or designing a net-zero energy structure, modern technologies and materials can help you achieve your goals. Such systems achieve energy savings by maximizing beneficial heat transfer and natural lighting through window, and minimizing use of artificial lighting and the traditional HVAC system. Smart Window is an exploration into sustainable development, which intends to create a superior indoor climate for building occupants and positively influence humanity’s ability to capitalize on renewable resources. Due to rising energy costs, advanced energy-saving technologies, such systems are gaining market advantage by saving money and alleviating stress on an increasingly problematic energy sector. In addition to a few interesting articles on novel fenestration systems, this edition of the magazine presents a number of enlightening articles on new-age façade materials and technologies, acoustic properties of glass, smoke and heat exhaust systems, etc. As always, we are very much interested in your thoughts on how we might improve façade & window experience and assure your continued participation in our future editions. With this issue, W&F Magazine has taken a step further towards the future to investigate how to optimize livability and sustainability in future buildings.

uPVC windows & doors are the best bet for anyone who is ignorant about their doors and windows. It is environmental-friendly, rust and corrosion resistant and hence has increased longevity as compared to others. The technology, design and the testing process for the uPVC doors and windows helps to bring out their unique properties. As a tradition in India, we have seen that the doors and windows are done by a carpenter who is known to a family or through someone’s reference, and who primarily uses wood, mild steel or aluminium as frames over some glass and uses some basic hardware such as handles, shoot-bolts and hinges to create the structure. But the life span of those windows is very short.
uPVC windows have many advantages
10 WFM SEPT - OCT 2017
Globally, windows have come a long way from being insignificant to being recognized as the single most important area in a building for preventing energy loss and providing inhabitants with comfort. The primary objective of the division is to innovate and
High performance and durability of uPVC windows & doors requires the following technical qualities: uValue (W/m2K): This measures how well a window is able to prevent heat transfer across itself either from outside to inside, or vice-versa. The lower the u value, the better is the windows’ insulating value. Today, state-of-the-art window making technology ensures u values of even 0.2 W/m2K.uPVC windows have uValue 1.5 to 1.7 W/m2K. Solar Heat Gain Coefficient (SHGC): This measures how well a window blocks heat caused by sunlight. It is expressed as a number between 0 and 1. The lower the SHGC, the less solar heat the window transmits.

create quality products that would enhance the new-age building architecture. Apart from this, windows today also have to ensure low/high solar heat gain (depending on climate), day lighting, noise attenuation, low dust ingress, air/water tightness, aesthetics, low maintenance requirements, and the likes.
Visible Transmittance (VT): This measures how much light comes through the window. VT is expressed as a number between 0 and 1; the higher the number, the more the light is transmitted. Air Leakage (AL) cfm/Sqft: When air infiltrates through cracks in a window, heat gain from outside or cooling loss from inside can happen. AL rating is expressed as the equivalent cubic feet of air passing through a square foot of window area. The lower the value, lesser the AL. The uPVC windows and doors are welded to ensure that there is no air gap.

laminated, tempered, sound resistant, insulated, bent and yes, even bullet proof glasses that are available in the market today and this range of glass is known for its strength and sturdiness. Selection of Hardware: Selecting the best fit hardware for uPVC doors and windows are key to the performance. Hardware available are handles, hinges, friction stays, door locks, cylinders, multi-point locks, rollers, threshold, door closers, etc. For handles- looks, quality, design and colour matching the profile should be given the priority. The selection of right hinges and rollers depends on the panel size and weight.
A premium uPVC manufacturer uses a formulation that meets the weather conditions in India
Water Tightness: Is the way to measure how much water can infiltrate through cracks/joints in windows. This is an important test for coastal and/or heavy rain areas.
Selection of Appropriate Profile: The design of the profile is important to get high performance of the doors and windows along with the aesthetics. We need to understand the way it is manufactured and fitted. Good quality hinges and locks, well-engineered reinforcement used where necessary and the right screws in the right places with the precise measurement of the window are the factors that play an equally important part. With the strengthening of properties like galvanized sections of steel, the profiles that are attached to the doors and windows have a more sturdy finish. The frame manufacturer should ensure that the frame has sufficient rigidity to stay within the permissible relative frontal deflection limits.
Noise Attenuation or Reduction: Due to their better seal ability and product integrity, uPVC windows ensure that noise from outside does not come into the habitable area. This property is important for hospitals, hotels, educational institutions, and constructions close to noise centres, etc. Wind Load Suitability: Windows have to withstand higher wind loads, particularly in windy locations, coastal areas, high rises, etc. uPVC windows are designed and reinforced to withstand even 3,000 Pascals of wind speed (equivalent to 245 km/hr of wind velocity). Types of Glass Used: Choice of glass can really impact the performance of doors and windows by affecting energy savings, views, privacy and security. Different type of glass, like security glass of up to maximum 28 mm thickness, is recommended for installation. One has to understand that glass fitting is just as important as the installation of uPVC doors and windows. That is exactly why this technology also comes with an offer and the choice of an entire range of glass that can easily be fitted into these uPVC frames. There are choices of

A premium uPVC manufacturer uses a formulation that meets the weather conditions in India. The right levels of all components are critical. “Titanium dioxide” provides the UV stability and colourfastness for the white profile. This compound protects windows and doors from discolouring. Titanium has a very high price and hence the premium doors and windows costs are high. The outer wall thickness of profiles should be minimum 2.2 mm and above (2.8mm A grade) for better functioning. Installation: Installation of uPVC windows & doors are very critical. The profiles should be cut to length and welded to 45 degrees. The window unit should be designed such that the water drainage does not pass through the reinforcement chamber. The window system should be fixed directly to the brick wall using self-expanding nylon plug and driving MS zinc coated screws into the plug. Lead free unplasticised polyvinyl chloride (uPVC) is a rigid and chemically resistant form of PVC. It has various advantages which are enhanced to meet the customers’ expectations, such as need very less maintenance and are much stronger as compared to traditional wooden and aluminium products. Unlike wooden products, when exposed to damp weather conditions, uPVC products do not swell or warp. uPVC’s durability is absolutely unquestionable.
Laminated sliding door
When compared to the aluminium counterparts, uPVC doors and windows are hands down better in terms of security, appearance and most importantly, the value for money. Apart from temperature, uPVC products remain unaffected by termite, rust, corrosion and dust. Keeping the above advantages of uPVC, we need to educate the Indian customers. Durability, comfort and style are further enhanced by engineered design for excellent insulation and easy clean, low maintenance surfaces. There is a range of uPVC doors for bedrooms, living rooms and balconies while the uPVC widows can be attached almost anywhere! There are options for sliding doors, fold & slide doors and in the case of windows, there are casement windows, sliding windows, and tilt & turn windows.

uPVC windows& doors are increasingly becoming the material of choice for achieving economic and environmental balance as well as meeting higher demands on inhabitant’s comfort. With the natural resources dwindling fast, traditional products are becoming more expensive. At the same time, the requirement of building materials is increasing by many folds. uPVC windows and doors are making an enormous contribution to many different aspects of infrastructure development and hence need to be on every architect, interior decorator or builders radar screen.

HOW TO SELECT THE RIGHT UPVC PROFILE SYSTEM About the Author: Robert Höllrigl is the Executive Director of R&D at Encraft India Pvt. Ltd. He advised this truly Indian venture since 2006 and joined Encraft full-time in 2013.

fabricators and general public. India is no exception, hence Encraft’s attempt to highlight important considerations when selecting a uPVC profile system. 1. Ensure that the uPVC profile system you are buying is from a reputable brand meeting the European standard EN 12608-1:2016 (uPVC profile standard) and the uPVC profiles are 100per cent lead-free. Ideally, the uPVC window and door systems design shall reflect India’s unique fenestration requirements. 2. Ensure that that manufacturer of the uPVC window and door system shall be able to provide a test report/test certificate that covers at least 8000 hours artificial weathering testing in accordance with EN 513 which is included in EN 12608, the uPVC profile standard. Please note: EN 513 test results obtained for 6000 hours European severe climate may not be sufficient for India’s tropical conditions. 3. Confirm that the depth of the profile system can house sufficiently large reinforcement sections

to cope with local wind conditions, security and safety requirements. 4. Ensure that the chosen steel reinforcement thickness is based on facts and calculations and shall not be below 1.0 mm thickness to ensure sufficient screw retention. 5. Make sure that the hardware is of good quality meeting expected life cycle and corrosion resistance requirements. The hardware must be compatible with the window and door system. Also ensure that the strikers and keeps are designed to suit the profile system because performance, security and long-term durability will depend on those dedicated components. 6. Ensure that the quality of the rubber gasket meets national or international standards, especially in terms of recovery rate, which is an important prerequisite for dynamic weather-seals and longterm performance. Nowadays, modern gaskets are sulphur-free, recycle-able and do not release carbon black whilst frame cleaning. 7. Ensure that your uPVC system can provide solutions for modern European and traditional Indian fenestration applications. The system shall offer as much interchangeability as possible; it shall provide solutions for the various glazing requirements; it shall offer static coupling options and a comprehensive ancillary range to fulfil the needs of today’s Indian architecture. 8. Confirm that you know more facts about the uPVC offering before purchasing and/or

specifying because there are so many misleading misconceptions. Old, entrenched marketing arguments are still being promoted throughout India. Some of them, no one can really explain, for example, the genuine justification for thicker walled uPVC profiles, especially for emerging markets (like India) that are striving towards cost effectiveness and raw material sustainability from day one. Even European uPVC purists or uPVC hardliners can only come up with 3 ‘light-weight’ arguments for thicker walled profiles like better screw retention, increased weld strength and frame U-Value reduction. Those historic arguments are easily refuted nowadays by facts and figures. Compliance with the European standard EN 12608-1:2016 makes any further discussion about profile quality and suitability, superfluous. NOTE: EN 12608-1:2016 covers uPVC profiles used in 28 EU countries, spread over two climatic zones and hundreds of countryspecific fenestration applications. In the absence of an Indian Standard for uPVC profiles, EN 12608-1:2016 has been chosen as the reference and benchmark. There are many more points to consider when starting in uPVC fenestration, but selecting the partner with the ‘right’ uPVC window system is probably the most important decision.

Natural smoke and heat exhaust ventilation improve the indoor safety condition in case of fire inside a building.
MAIN RISKS DURING FIRE In the event of fire inside of a building, smoke and hot gases rise up in the building, creating a layer of dangerous gases under the ceiling, which fill up the room in a very short time. The smoke precludes the visibility of the emergency exit or impedes the prompt intervention of the firemen. Due to the toxic substance of the smoke, the 90% of fire victims die due to smoke inhalation. The second critical risk is the flashover caused by the very high temperature inside the building that could generate explosion or big damages to the building structures, with the consequent collapse.
WHY USE SMOKE VENTILATION? For avoiding the above dangerous events and keeping escape routes clear for longer, and also to

NSHEV DEFINITION NSHEV systems can be divided in two main categories: Façade Exhaust System (vertical façade). Roof Exhaust System. The NSHEV consist in an electrical drive installed and operating on vertical or horizontal window design and developed for resisting to very high heat (up to 300°C) and reliability (up to 10,000 cycles) tests.

Offices, schools, hospitals and rest homes are – just as homes – intended to provide people with a suitable working, learning and living environment. So it is very important to create a healthy indoor environment and minimise the energy needs of those buildings. Thermal, visual, acoustic comfort and a supply of fresh air are the basic elements for a comfortable indoor environment. It goes without saying that sufficient fresh air is important. Just opening windows is not enough. You need continuous, controlled ventilation, but the main problem with full mechanical ventilation is the risk of contamination. Thermal comfort means that it is not too hot or not too cold - a pleasant temperature all year round. Of course, this is often subjective and sometimes calls for personal control. If you have large glass areas, particularly facing south, controlling the temperature in the summer is not always easy as there is the problem of overheating. You need to be able to allow sufficient daylight in without glare or annoying reflections

Continuous controlled ventilation and lighting are essential for indoor comfort
during the day, use pleasant artificial light in the evening and have effective light exclusion at night. The view outside is also important. When it comes to living comfort, looking onto a garden is more desirable than gazing at a bare factory wall.

Hence an unhealthy indoor environment can lead to: Respiratory problems Dry throat Burning or irritated eyes Headaches Allergies Lack of concentration Grogginess Listlessness Drowsiness Basic ventilation provides good air quality into the building (IAQ or Indoor Air Quality). Sufficient fresh outside air expels the polluted inside air from the building using the principle of supply, transfer and extraction.
Sufficient fresh air is important aspect of indoor environment
AIR QUALITY AND HEALTH Excellent insulation without enough ventilation produces “dead” air in buildings where dust mites, moulds, viruses, bacteria and even dangerous chemical substances (CO2, CO, radon, VOC) can accumulate. Each time we breathe in, our lungs could inhale these microscopic particles. They then could pass through the bloodstream to invade the adipose tissue, kidneys, liver, glands, etc.

DYNAMIC EXTERNAL SUN PROTECTION A building or home with large glazed surfaces facing south can offer many advantages. During the autumn, winter and spring, you can enjoy the benefits of the incoming sunlight. However, in the summer this can lead to overheating and an annoying glare on TV and computer screens throughout the year. Structural sun protection and sunscreens can prevent this overheating and limit the amount of glare. They stop the sun’s rays before they come into contact with the glazed surfaces and the undesired heat and blinding light from entering the building. And yet you can still keep that important visual contact with your environment. So external sun protection is needed
Structural external sun protection consists of extruded aluminium blades which can be fitted continuously or in a frame
to control the entry of the sun’s heat. It is not only necessary for buildings with a lot of glass facing south, but also for those with a fair amount of glass on the western and eastern façades. Combined with wisely chosen glass, fabric sun protection screens are a perfect compromise between heat control and light entry. The photometric properties of the glass and the sunscreen, such as the reflection, absorption and transmission properties, help produce the gtot value (the shading coefficient, previously called SC). The gtot value indicates the shading efficiency of the chosen glass/ screen combination. Other fabric properties are the openness factor and the uV transmission rate. This dynamic sun protection is wind-tight in large surfaces as well. Opening it in winter, permits the sun to warm up the building for free. In summer fabric screens protect from overheating inside. Structural external sun protection consists of extruded aluminium blades which can be fitted continuously or in a frame. These sun protection blades can be fitted above windows in the southfacing façades: horizontal awnings like these are the ideal solution for controlling heat entry from sunlight but without blocking the view. They are the perfect protection in the summer, when the sun is high. In winter, when the sun is low, they let the warmth into the building. Blades like these can also be mounted vertically before a glass surface.
VENTILATION AND SUN PROTECTION FOR HIGH RISE BUILDINGS There can be totally different requirements applicable to high-rise buildings in terms of ventilation, sun protection, and terrace coverings compared to normal construction: perfect alignment with every type of curtain wall and aesthetic integration,

for example, without losing energy efficiency or durability. The result is often custom-made, providing a solution that not only conforms with all the visual performance requirements, but also meets all the requirements in terms of health and a comfortable indoor climate. Studies have shown that no less than 80 per cent of people in high-rise office buildings or apartment buildings still want to feel like they can bring fresh air inside. But opening a window is not always an option in this case. Luckily, there are plenty of customised ventilation louvers that always provide a great alternative to supply the necessary fresh air in the curtain walls that are so often characteristic of high rises: aesthetically integrated and compliant with the requirements for acoustics, wind-resistance, airflow, rain, insects, security and the possibility to regulate this yourself.
Large glass panels ensure that there is sufficient daylight
Large glass panels ensure that there is sufficient daylight, but at the same time, the direct incoming sunlight often disturbs the visual comfort and increases the risk of overheating during hotter period. Increasingly better insulated high rises definitely include external solar protection to deflect the sunlight before it has a chance to reach the glass. This helps to avoid increasing costs for active cooling.

This glass ceramic material is almost 100% recyclable. Glass ceramic plays an important role in the careful use of natural resources and improvement of the sustainability balance in building projects and design objects. This is an enormously important factor in view of ecological requirements. When polished, glass ceramic emits a radiant shimmer, and when patinated/leather surfaced, it has a unique

You can, of course, state all glass is recyclable, but in fact to create fresh clear glass from broken cullet one has to use very high temperatures of 1200 deg C which creates a heavy carbon foot print, whereas this product is sintered at around 700 deg C to hugely reduce this negative aspect to around a third of the comparable energy input.
GLASS CERAMIC FOR EXTERIORS APPLICATIONS Glass ceramic can be used as a rain screen material as one sees with natural stone slab. However, it has advantages over stone on evenness of colour
Particularly awe-inspiring is the magnificence that results when a piece is back-lit, bringing a charming and warming 3D visual effect.
CRYSTALLIZED UPCYCLED GLASS CERAMIC Glass ceramic is essentially upcycled trade waste glass which is crystallized, but acts like neither glass nor stone. It is a material with more life in it than a clear glass sheet, a material with more evenness and control than natural stone slabs. Glass ceramic is an entirely new sheet material which incorporates the advantages of glass and the beauty of natural stone in one material character. Glass ceramic is a cladding product that envelopes a design with a timeless and luxurious mantle, a material which not only offers the play of light of a semi-transparent material, heavy durability and low

Applications can be divided into two main types: open ventilated rainscreen and closed curtain wall but one should say that we can divide it into types of design effect through the level of translucence or one can divide into the method of fixing and detailing. Safety is achieved via lamination to glass or using safety films and also helps bring in transparency, as well as a link between the interior and exterior space with the least adjustment.
FIXATION AND TECHNOLOGY OF GLASS CERAMIC The well-known German fixing specialist Fischer AG has successfully developed the undercut FZP-15x15.5 M8/16 G-Z especially for glass ceramic façades. These can be fitted into the back of every façade panel, according to the required structural needs. Structural glazing of façade panels is also suited to mount glass ceramic on interior walls.

The Indian fenestration industry has undergone many changes in terms of engineering and material usage over the years. Wood windows have been in use since the birth of the building construction. Other building elements like steel and aluminium came much later, i.e., in late 20th century, and only recently uPVC has been introduced in India. Let’s have a look at the evolution of the fenestration industry in India.
THE ERA OF PRIVATIZATION The active growth of Indian building/construction industry happened in the late 90’s and early 2000s, when the IT complexes were sprawling across the country, starting from Bangalore to Hyderabad and Mumbai, Delhi and then Gurugram. Almost all the major real estate developers, such as DLF, Unitech, Hiranandani, Rahejas, Prestige and Brigade started paying attention on constructing state-of-the-art buildings, made using the latest technologies and designs available in the market at the time. Owing to the sudden growth, curtain wall fabricators

could be seen juggling with projects related to the commercial structurally glazed buildings. All major 15-20 fabricators took big glazing jobs and changed glass from sheet to float and later processed glass. Aluminium extruders were not far behind, with operations running 24x7 and earning millions by churning tones of box sections for the glazing

industry. Analysing the industry progress in late 20th and early 21st centuries, it could be seen that the growth was very optimistic with the developers concentrated on the commercial buildings as opposed to the residential or mass scale housing.
FENESTRATION MARKET IN 21ST CENTURY The first few years of the 21st century were a period of general economic decline observed in world markets. For the first time ever the real estate industry started to see windows being sold as a complete system instead of just sq. ft. basis. From 2002 on, due to the lack of efforts towards good fenestration and windows, proper attention was given to window installation. Moreover, the need for upgrading many housing standards aroused. Fenesta, Indiaâ€™s largest windows and doors company, was launched in 2003 in technological collaboration with UK-based Spectus. Spread across 120 cities and a part of 5,200 crore DSCL group, Fenesta is the pioneer of uPVC windows in India. It has adapted the best of European technologies to develop products, especially suited for the Indian market. Thus uPVC windows were introduced in the Indian fenestration market. It is only fair to say that Fenesta make windows a Product Category and paved the way for the uPVC Industry.

Back in 2004, Southern India, led by Bangalore, was quick to accept uPVC as the new age window material followed by other regions. uPVC windows were booked in large orders with builders like Brigade and Prestige within first few months of starting the business. The growth extended to other regions and a millions of uPVC windows and doors were installed across the country. The product emerged as one of the most preferred material for windows and doors amongst end users and large developers.
THE GLOBAL MELTDOWN The commencement of 2008 brought downfall for the real estate owing to the worldwide recession. There was over-capacity and there were much more real estate, commercial and residential buildings available than in demand. Announced projects were put on hold and real estate companies took a big hit on losses, both in cost and space. Parallel to this, the fenestration industry also saw a decline in sales and demand. The later part of the first decade saw a slight uprising in the reale state sector again and the uPVC industry started to grow positively. The window manufacturers started getting loads of orders from residential projects with the housing boom. In a time frame of only three to four years, all major

European and Turkish players and system sellers like Veka, Aluplast, Kommerling, Rehau, Wintech, etc., established in India along with many Chinese players. Events were organised to boost the sales of the products and machines for the uPVC industry and it was observed that more than 20 new uPVC fabricators were entering the market each year. The fenestration industry has come into its own in the second decade of 21st century onwards, marking its territory and establishing itself independent rather than just being related to architecture or facade. End of the first decade saw more than 150 uPVC door and window manufacturers in India (maximum in the South, then North, West and East of India), each of them making their uPVC windows popular to the developers in their respective regions. Developers understood the advantages of using uPVC window systems and chose it for various reasons. Window prices had increased from Rs.150-180 per sq. ft. for section aluminium to Rs.300 to 1,000 per sq. ft. Windows were sold in retail for individual homes by the uPVC window manufacturers. A home owner could order a window and expect to receive the real quality window with standard specifications which is perfectly sealed and packed. The aluminium window & door industry had also taken many encouraging initiatives. They had developed system windows and offered them to builders and developers. The evolution of the window industry helped enrich the knowledge of the aluminium hardware too. In the early part of this century, aluminium framed windows accounted for approximately 60 percent and remaining 35 percent together equalled wood, steel and uPVC account for approximately 7 percent. However, the introduction of the vinyl framed

Large doors and windows are ideal for bringing nature indoors
ALLIED INDUSTRIES Many major window manufacturers were keen to make sure that the windows installed by them were perfectly waterproof, weatherproof, and acoustic and thermal insulated. To obtain the perfect finishing, they worked together with sealant manufacturers. Thus silicones were introduced to the fenestration uPVC industry. After silicones in 2003, acrylic sealants came in 2005 which was followed by PU foams in 2011. Today, all major uPVC window makers use sealants and foams since they are part of this revolution of the fenestration market. Sealant manufacturers trained their staff (applicators and employees) to make sure the windows are installed perfectly, making them waterproof, weatherproof, acoustic and thermal insulated to obtain perfect finishing. Many workshops were organised to train the applicators at different locations. These workshops had live demonstrations and videos to make the training more educational and interesting. Efforts were made to create an informal

atmosphere and foster interaction between technocommercial people and the participants over the live demonstration. These workshops had been attended by hundreds of participants from leading uPVC window manufacturers in India. Thanks to hundreds of uPVC fenestration manufacturers, their meetings and discussions with builders, developers and real estate owners on the effective use of silicone, sealant and PU foam have made the products in widespread use and become more popular in the industry as well. Sealants were also used in wood, aluminium or steel window joints to finish them perfectly and make them leak proof. Now it is well understood that silicones, acrylic sealants and PU foams have to be used in during the window installation for better results.
PRESENT SCENARIO Positive construction spending and renovation in existing constructions are expected to drive demand for windows and doors. Rising population would support the window and door market share for new constructions serving residential, commercial and commodity requirements. Commercialization, improving government and state finances and public funding in India will further enhance the business growth. As per the report published by the Global Market Insights, Inc., global Window and Door Market size were valued at over USD 82 billion in 2015 and is forecast to grow at 5.6 percent CAGR from 2016 to 2024. This revenue refers to window and door system or profile sales. Global demand was over 28,000 kilotons in 2015. It will witness steady growth at 3.9 percent.

with growing improvement and repair demand across the residential and commercial sectors will drive the global window and door market size. In similar lines, Indian fenestration industry too will grow at a faster pace. Product preferences vary widely based on parameters, such as price, quality, environmental friendliness, aesthetic appeal, etc. Regional housing and commercial construction markets as well as raw material adoption based on the required characteristics will continue driving demand. The uPVC window and door market share accounted for less than 10 percent of the overall revenue in 2015 and will post a high CAGR in the coming years. This growth can be attributed to demand for light weight and energy efficient profiles that require less maintenance. The material provides a good level of insulation against outside noises. Moreover, its fully recyclable property would attract more attention over the next few years. Metal profiles will grow at over 5 percent CAGR, mainly due to attractive aluminium window and door market size in some regional industries. Aluminium provides low maintenance and coated frame which can be painted and be matched with the colour of the user’s choice. There has been increasing government support to adopt uPVC profiles due to superior energy efficiency
Introduction of new technologies in the profiles such as use of uPVC instead of aluminium and wood would support demand owing to the material’s fully recyclable property, lower weight, lesser maintenance, and thermal insulation. Favourable maintenance and operating cost of these profiles has led to growing adoption on a global scale. Wide scope in household and commercial is likely to present considerable growth opportunities. The segment was valued at USD 27.5 billion in 2015 and would reach USD 47 billion by 2024. The utilization of low standard and inferior materials in the past has gained a bad reputation for environmentally friendly products. Recurring high maintenance costs over the period of five to eight years in the past also has impacted the industry negatively. However, the forecast time frame may provide better growth prospects for eco-friendly products owing to the rising awareness among the people regarding the importance of environmental conservation.

The popularity of uPVC products is going to reach new heights in the coming years
At present, the market for uPVC products in fenestration industry is just about 10 percent. But the popularity of uPVC products is going to reach new heights in the coming years with the positive growth in construction industry. The reason being its price competitiveness at the expense of quality (Rs.350/Sq ft (standard); Rs. 900/ Sq. ft. (special)). There are over 150 fabricators in uPVC sector. The trade per retail is Rs. 200+/ Sq. ft. With over 80 percent of it being unorganised, the industry also faces difficulties due to lack of standardisation. Raising awareness regarding the benefits of uPVC and lesser maintenance would trigger its use in the new residential construction market. Wood window and door market size accounted for over 28 percent of the overall revenue in 2015 and would grow at 5.7 percent from 2016 to 2024. High thermal resistance, aesthetic looks and easy availability of timber would support the growth over the forecast period.

CONCLUSION The Indian fenestration industry is directly linked to the construction industry’s performance. The overall growth is around 20 percent annually. The retail is still on a steady growth path, though project business has shown a slump in the last couple of years. But in the near future, with huge projects announcements from the Government like 100 smart cities, and with the propositions by the Planning Commission to build over 20 million new houses in the next 10 years, the real estate sector in India continue to seek greener pastures. Thus the related segments, including windows & door market will vroom again, though the past few years saw a decline in sales.

“The history of architecture is the history of the struggle for the window” - Le Corbusier Today, the world’s number one priority is to tackle climate change. As buildings account for 40 percent of the greenhouse gas emissions, saving energy and carbon emissions are top priorities for buildings and construction sector. It is predicted that by 2050, about 40 percent of carbon emission will be due to the carbon footprint of buildings. With up to 60 percent of the total energy loss of a building coming from windows, fenestration products have a huge potential to provide large energy savings. Therefore, windows with a low thermal transmittance or U-value are opted for since they can substantially reduce energy losses and save costs. In recent years,
efforts have been made to implement building codes requiring lower U-values for new windows, and this trend is set to continue as government seeks to save energy and reduce emissions. To obtain an overview and deeper understanding on advanced fenestration materials and technologies, WFM approached various industry experts, including window and profile manufacturers, fabricators as well as architects.

beyond being simple devices that let in light and air, and function as integral components of complex building envelopes, selectively filtering traits of the larger environment. As manufacturers have developed new technologies to improve visibility, security, and comfort, windows have become elements of sophisticated systems that control light, ventilation, moisture, dust, sound, and even infrared and ultraviolet light. Research and development into types of glazings have created a new generation of materials that offer improved window efficiency, performance and comfort for consumers, says Amit Bhadu, Marketing Manager, Technal India. Effective technologies cover the aspects of sound insulation, heat transfer, resistance to higher wind loads, durability of hardware, performance of glass, improvised surface treatment merging with adjacent interior finishes etc., spots Amit Klinger (Managing Director, Alumayer Group).

The time will come when double glazing is being required mandatory in India to combat CO2 reduction and to save energy with better fenestration. Will India then adopt the traditional air/gas filled double glazing technology or will it leapfrogs the rest of the world and introduce vacuum double glazing, questions Höllrigl.
PREFERENCE IN MATERIALS Talking about the preference in materials, Rajesh Chawla (Director, Veka India) shares that the preferred fenestration materials are uPVC & aluminium. Wood & MS are losing on to various aspects like sound, heat insulation, cost and environmental factors. In uPVC & aluminium, the advancement is particularly in terms of profile designs and classification. Better designed systems with much higher degree of sound & heat insulation in both materials impart much better functionality for larger span of times.

errors. We have seen people calculating price wrongly, especially in large volume projects, says Col Shailesh Pathak. The correct way is to calculate price for each and every window and door as each will have different thickness of glass and different load capacity of the hardware. This is only possible by using a software. The software is an essential tool not only for financial calculation but also to manage the entire production and sales management. Amit Klinger points out that software automates and connects every aspect of fenestration starting from
sales, design, procurement, planning, fabrication, inventory control, logistic, project execution, billing, accounting transactions, etc. Basically, it increases the ability of an organisation to handle more projects. Mario suggests that fenestration software is the key factor to scale up from the unorganized sector into an organized industry. Let’s look at the roles of fenestration software in major functions like design, fabrication and installation. According to Nandha Kumar, while designing windows, software helps to check feasibility and
DESIGN DYNAMICS FOR EFFICIENT FENESTRATION Openings in a building’s façade are very critical component for evaluating efficiency and lifecycle of the building. In order to find the most cost effective solution, the whole building performance approach should be used towards achieving the efficiency. Fenestration and façade has an impact on the interior spaces as well as on external neighbourhood. One of the basic design motives for the building envelope is to protect the indoors from external elements along with providing optimum daylight and to optimize the solar heat gains in the building. This can be achieved through simple passive low cost measures based on the principal of demand reduction through building envelope design by controlling Window to Wall Ratio (WWR) , SHGC , U value(Based on choice of building material).
Hiten Sethi, Founder, Hiten Sethi & Associates
The WWR can vary from design to design. Having the right ration ensures the efficiency. Appropriate shading with respect to orientation with combination of high performance glazing ensures compliance with SHGC requirements as per ECBC. For moderate climate, the prescribed SHGC for a design with WWR < 40% is 0.4. Indoor daylighting is achieved by providing glazing having specific VLT values and efficient space planning. Another important design motives of a window is to maximize the external views while causing minimum glare. The daylight analysis of the design at regularly occupied spaces should be carried out at the designing stage itself to ensure that they are adequately lit as per the required task based lux levels. These levels can be achieved through appropriate design of the spaces along with right shading devices and glazing specification.

information and pools resources and offers genuine time savings for stakeholders, industrialists, installation companies, clients and project managers. Besides CAD systems, says Höllrigl, fenestration providers utilise dedicated fabrication computer systems that can cover wind loading, accidental loading, frame weights, U-values, sales order processing, production planning, pricing, stock control, fabrication cutting sheets, links to machining centres and accounting. Other software is mainly used by the systems provider for R&D and support purpose like U-value simulation, gasket simulation, static and stress calculations, sound reduction programme, etc. Goenka Bugalow, Goa by Veka

In order to build faster, Amit Bhadu of Technal highlights that we must modify our methods and move from sequential to collaborative workflows. Through digital 3D modelling or BIM, it is possible to create unique evolving projects. It centralises
Not all software’s are made equal, says Col. Pathak. Some only calculate pricing, some are used for designing based on the profile, hardware and requirement. Some can manage entire business. Selection of software should be based on business planning, profile and hardware system. Regular maintenance and updating of software is required and involve additional cost.
HIGH PERFORMANCE WINDOW/DOOR In today’s scenario, energy efficiency and quality are the top considerations for choosing windows.

No water ingress (when tested at 300 Pa – class 7A - EN 12208) 3. Wind resistance depending on location (min. 1600 Pa – class 4 – EN 12210) 4. Lowest possible U-value (max. 2.8 W/m2K or lower – ISO 10077-1/2) 5. Highest possible sound reduction (min. 34 dB or higher - EN 12758) 6. Hardware shall be able to perform to 20.000 cycles (class 3 – EN 12400) 7. Hardware fitted (hinges, locks, handles and screws) shall pass 480 hours salt spray testing (grade 5 – EN 1670, EN ISO 9227) 8. Frame shall meet the basic security standard (class RC2 – EN 1627) The above outlined high-performance specification is based on Höllrigl’s opinion and experience. It is a ‘safe’ specification that can be used throughout the Indian subcontinent covering today’s and tomorrow’s requirements like CO2 reduction, energy savings, sound reduction, reduced air leakage, durability and frame security. NOTE: Some frame types like the conventional 2 or 3 track horizontal sliding window may not be able to meet the outlined specification due to the inherent sealing arrangement. Thus, may require accepting a lower air permeability class (feature 1) and/or water tightness class (feature 2) but the remaining features can be still met as outlined.

KEY CHARACTERISTICS OF HIGH-PERFORMANCE WINDOWS When we talk about high performance windows and doors, explains Col Shailesh Pathak, we mainly concentrate on energy efficiency, performance, sustainability, and occupant well-being. Let’s take them one by one how these can be achieved: 1. Energy Efficiency a. Double/triple glazed unit b. Low “E” Glass c. Co-extruded gasket d. More than 3 chamber profiles in uPVC profile system e. Thermal break aluminium profile systems f. Energy efficient hardware systems like lift and slide systems 2. Functional performance a. Multipoint locking system b. Water tightness c. Sound reduction d. Weather resistant e. Threshold in doors for water, sound and air tightness f. Easy operation g. Safety & security h. Design as per region and location 3. Sustainability a. Long life. Longevity and endurance
According to Vengateri and Amit Klinger, the main indicators of high performance are thermal insulation, water tightness, air permeability, wind load resistance, noise reduction, burglar resistance, higher durability and reliability. Better thermal performance is achieved by adopting thermal break system. High performance glass and selection of double glazed unit also contributes significantly in improving thermal performance. Higher durability, reliability and weather resistance are achieved by appropriate selection of extrusion system, hardware, etc. Nandha Kumar T elucidates that high performance window/door needs to comply the following: High UV resistance property i.e., to confirm the severe climatic ‘S’ zone condition at 8000 hours of simulation with ∆E value below 5; air permeability and wind resistance test compliance as per BS EN 1026 and BS

b. Maintenance free. No need to paint after some interval, limited hardware maintenance c. Environmentally safe d. Recyclable. Green product 4. Occupant well-being a. Condensation resistant b. Planned ventilation c. Low VOC d. Aesthetically good e. Ease of operation specially for elderly and kids (As told by Col. Shailesh Pathak, Managing Partner, Green Fenestration Technologies)
EN 12211; and water tightness and penetration test as per BS EN 1027. Manufacturers usually represent the energy efficiency of windows in terms of their U-values (conductance of heat) or their R-values (resistance to heat flow), adds Amit Bhadu. If a window’s R-value is high, it will lose less heat than one with a lower R-value. Conversely, if a window’s U-value is low, it will lose less heat than one with a higher U-value. In other words, U-values are the reciprocals of R-values (U-value = 1/R-value). Usually, window R-values range from 0.9 to 3.0 (and U-values range from 1.1 to 0.3), but some highly energy efficient exceptions also exist. When comparing different windows, you should ensure that all U- or R-values listed by manufacturers are calculated for the entire window, including the frame, and not just for the centre of the glass, and represent the same size and style of window.

LATEST ADVANCEMENTS IN PROFILE TECHNOLOGY
away from home and you can open and close your sashes.
From stone doors and windows in our ancient forts and temples to uPVC doors and windows of our modern time, the industry has undergone sea change. Three profile types – wood, aluminium and uPVC – are commonly used. Our wooden windows, for instance, says Mario Schmidt, where the frame and shutter sections are glued out of different parts, the profile stands without any bending or curving even during the monsoon. High technology paints are withstanding the harsh climate condition and the surface treatments stands for years without discoloration. All hardware and glazing systems, similar to uPVC and aluminium, can be used in wood profiles too.
SMART GLAZING FOR WINDOWS
Considering aluminium architectural systems, they get better, year by year, says Vengateri. Thin profiles with extremely sophisticated profile architecture, taking advantage of the excellent mechanical properties of aluminium, lead to exceptional windows and doors with high sturdiness and outstanding design. Frames (profiles) must be able to impart higher degree of insulation, and very importantly, they should be recyclable, says Chawla, Veka. Amit Bhadu adds that new approach aims to eliminate thermal bridging, condensation and mould from our living room windows. Höllrigl explains that advancements in profile technology is to improve the thermal efficiency even further and trying to avoid the cumbersome foam filling process associated with all frame materials. Thermal efficient fenestration will provide benefits like CO2 reduction and energy cost saving. “Unfortunately, profile technology, although still important, is now playing a smaller part in fenestration and some perceived technological advancements like uPVC and GRP co-extrusion has been an expensive flop whereas the composite profile technology is gathering momentum”, adds Höllrigl. Combinations of aluminium/wood, aluminium/uPVC, uPVC/wood and aluminium/GRP are being heavily promoted, outlining the aim of maximising the inherent benefits of the partnering framing materials. Electronics in fenestration technology is already being applied in commercial projects and high-end retail properties. Controlling the windows and doors with a mobile is not a myth anymore.

As you know, glazing is the main part of the total surface of a window, constituting averagely around 75 to 80 percent of its surface. Thus, its impact on energy efficiency, noise reduction and safety are huge. Smart glazing is the one with light transmission properties that are altered when voltage, light or heat is applied. Generally, the glass changes from translucent to transparent, changing from blocking some (or all) wavelengths of light to letting light pass through. According to Höllrigl, the principle of smart glazing can be best described as a dynamic environment, i.e., by pressing a button the glass can be tinted to keep heat and glare out whilst the best conventional double-glazing unit with low-e coating provides a static environment like fixed solar gain, fixed light transmission and fixed thermal transmission (U-value). When installed in the envelope of buildings, spots Höllrigl and Amit Bhadu, smart glass creates climate adaptive building shells, with the ability to save costs for heating, air-conditioning and lighting, and avoids the cost of installing and maintaining motorised light screens or blinds or curtains. Blackout smart glass blocks 99.4 percent of ultraviolet light, reducing fabric fading; for SPD-type (suspended particle

SMART GLAZING Multilayer: We have triple glazed units based on the requirement, but DGU are very common even in tier 2 or 3 cities as energy cost is increasing day by day and requirement of comfort has also become a norm than an exception. Privacy glass: Privacy glass is a laminated glass with a liquid crystal film inside. When there is no electric power supply, glass looks like frosted glass and when we supply power, it becomes the clear glass. This is an expensive glass, generally used in corporate offices and hotels. Vacuum glazing: It is comparatively a new development and saves us from using thicker DGU, with better thermal performance. As of now it is not available commercially for large size glasses. Low-emissivity coatings: Low “E” glass is a very successful green material and reduces the energy consumption to a great percentage. Not only it controls the temperature, but also reduces the energy consumption for lighting. Self-cleaning glass: This is the process in which a “Nano coating” is applied to the surface of glass, which prevent the accumulation of dirt and dust on the glass. This has some limitation of life, but can be applied again. Smart windows: These windows have specialised glass which changes their temperature control and shades of the panel using various process. i. Thermochromic: In this glass, tint changes due to change in temperature. ii. Photochromic: In this change is due to ambient light.

Architectural SPD products – windows, skylights, doors and partitions – are available as laminated panels or insulated glass units for new construction, replacement and retrofit projects. These products offer a distinctive blend of energy efficiency, user comfort and security, adds Amit Klinger. Regarding safety and noise reduction, one can choose among various laminated or tempered glasses or even glasses which combine both technologies. Furthermore, one can choose between different glazing thicknesses among single, double or triple

iii. Electrochromic: In this type of glass, the colour change is due to electrical energy as explained in privacy glass. Solar cell glazing: Photo voltaic solar cells are incorporated in the glass which is used in façade or canopy or any other glass application where we do not need 100 percent visibility. Glazing cavity gas fills: Air acts as an insulator so hot air is filled inside the DGU for insulation. If better performance is required, then “Argon” gas is filled. “Krypton” gas is also filled, but it is very expensive. Spacers: In DGUs to separate the two panes of glass, aluminium spacers filled with desiccant are used. There are two types of spacers: - Foam & Thermoplastic. All the materials mentioned above are available with top glass processors and fenestration companies in India, but their instant availability may be an issue as they are expensive and have problems regarding the shelf life.

WHAT ARE SUPERWINDOWS? “Superwindows” are efficient windows which can attain high thermal resistance by combining multiple low-e coatings, low-conductance gas fills, barriers between panes, which reduce convective circulation of the gas fill, and insulating frames and edge spacers. Also, optical properties such as solar transmittance can be customized for specific climate zones. The heat from even a small amount of diffuse winter sunlight will convert these superwindows into net suppliers of energy. This first generation of superwindows has a center-of-glass R-value of 8 or 9, but have an overall window R-value of only about 4 or 5 because of edge and frame losses. Also under development are chromogenic (optical switching) glazing that will adapt to the frequent changes in the lighting and heating or cooling requirements of buildings.
toxic) can be implemented in double & triple glazing panels for enhanced thermal insulation, points out Vengateri.Note that the Ug value indicates the energy efficiency of a glass panel. A low Ug value offers high energy efficiency. Last but not least, thanks to the advanced technology of polymer dispersed liquid crystals (PDLCs), glass panels’ transparency can be adjusted according to your privacy or natural lighting needs during the day.
AUTOMATION TECHNOLOGY Looking at the production side, high volume, streamlined product range and excellent production planning are pre-requisites for automated frame production lines. The required factory space, the high investment level and the occasional, unpredictable order intake have deterred most fabricators to make the big step change. It is not surprising that cutting/
machining centres, flat bed multi-head welder and corner cleaner combinations are chosen as the first step in automating. But the automation technology stops when sashes are merged into outer frames or when frames require factory glazing. Nevertheless, every operation in fabrication can be made more efficient by simple means like introducing automation. This is something expected to come in the industry during next one to two decades. In India, when the market is reeling under too much of price pressure, there is almost nil automation, either in extrusion or fabrication, points out Chawla from Veka. It can be argued that automation is only meaningful in high labour cost economies, but the inherent manufacturing quality and the consistent output per hour/day/week may be of interest in new, emerging markets like India. Looking at the products, automation is an uprising trend requested quite often by customers.The future of automation in fenestration is bright and strongly connected to what we call the “Smart” house, which will use IoT – technologies to regulate interior temperature and air ventilation efficiently, and always in accordance with safety. There are many automation sensors available in the market, explains Col.Pathak, which are unique to the window and door industry and to the security market as they detect lock and unlock position of the door and window. These sensors can integrate with a professionally monitored security system and are controlled via a security system keypad, smartphone or tablet app.

impressive range of products that can be installed across the residential, commercial and industrial segments.
TESTING & CERTIFICATION OF WINDOWS All windows are not made equal, nor are all components of window fabrication same. Every manufacturer claims his products are the best in the world. How can a customer select the correct product for his requirement? Here comes the need for testing and certification system. But in India there is no system of certifying a window and door system.
With high performance windows and doors, it is possible to save up to 30 percent of energy consumed for heating or cooling a building. To be sure of the achieved energy savings, and to be able to prove the insulation performance of a window or a door, it is essential to have certified it accordingly. The international code recommends various laboratory tests, which are conducted by third party testing agencies. The tests are carried out to ascertain that the system can withstand the parameters, considered during the design stage. This includes structural stability (wind load) acoustic performance, air infiltration, water penetration (static and dynamic) seismic racking test (floor displacement), structural proof load test (150 %) seismic proof load test (200%) etc. The testing concludes the performance of the system.
and make a rating system which should be simpler and easily identifiable. It should help architect in specifying the windows and customer to buy. uPVC Window and Door Manufacturers Association (UWDMA) is supporting the initiative with the Federation of Safety Glass (FOSG) to run awareness campaigns across the country and to brief architects and developers about this new rule. UWDMA has taken up this challenge to educate customers and manufacturers through their various programmes. Similarly, FOSG, Glazing Society of India (GSI), IIT Chennai are other organisation who are working on the standards and specifications. “But I feel that the government must come forward and take the responsibility to coordinate all these individualistic efforts and make a legislation, and also force everyone to adopt,” says Col. Pathak
Certification and testing is a very vast subject. There are many parameters on which windows and doors should be tested and certified. Major ones are enumerated below: Wind loads Site conditions Thermal comfort Energy Values (ECBC) Intruder preventions Materials NBC (National Building Code) provisions Verification
If an industry wants to set high standards, it needs certain specifications followed by everyone, says Vengateri and Rajesh Chawla. Reputed and big players in this field are maintaining world class quality, but there are a large number of unscrupulous manufacturers who produce poor quality products and cheat customers. Whole industry suffers due to this.
But these many parameters will confuse the buyer. So, the government needs to group the parameters

MORE ON TESTING The only appropriate test for building envelopes with installed frames is a site air permeability test. The principle is based on one external door with a fan fitted that extracts the air from the building envelope (building/dwelling/apartment). The resulting difference between external and internal pressure is being used to calculate the air permeability of the building envelope. The air permeability is a good indicator of how well the building is sealed and whether there are any gaps/openings in the building envelope. The U-value Hot Box testing for windows and doors, in accordance with ISO 12567-1, has been virtually superseded by U-value simulations to ISO 10077-
70 WFM SEPT - OCT 2017
2 & U-value calculations to ISO 10077-1. Today’s computer software solutions enable architects and fenestration engineers to design building envelopes and windows with maximum thermal efficiency in mind. Heat losses through windows and aperture joints can be highlighted and eliminated by calculation and simulation. For example - the result of re-positioning of the frame within the aperture or the change of glazing specification, even the choice of spacer bar can be instantly seen when simulating, thus helping to make considered decisions in the design stage. (As told by Robert Höllrigl, Executive Director of R&D at Encraft India Private Limited)

that their products will survive till the mentioned time, warns Mario Schmidt. They provide products at the price requested by the customer, but of poor quality, cutting down on all the technical specifications. Speaking on the absence of industry standards, Höllrigl states that there is plenty of excellent documentation in the public domain to ensure that well-known brands do not suffer. Standards or guidelines are missing is simply a myth, he adds. In the absence of the standard by BIS (which is still at the final stage with the department), and to assure the right movement of the industry, in February 2016 UWDMA introduced its guidelines for uPVC doors and windows fabrication and demands on materials. This provides a good practice guide and answers to numerous questions raised by fabricators, architects and builders. Talking about the standards, Höllrigl adds that within the supply chain, from extrusion tooling, raw materials (PVC and its additives) and to finished uPVC profiles, everyone works with EN 12608-1:2016. They test the materials/products, in accordance with the relevant clauses. EN 12608 has been officially introduced in 2003 and adopted worldwide as the most comprehensive product standard. According to Nandha Kumar, some of the technical issues which occur due to absence of industry standards are:
72 WFM SEPT - OCT 2017
Discolouration due to UV impact; non-compliance of right grade of TiO2 usage and insufficient dosage. Poor durability resulted by poor mechanical properties (charpy impact strength, tensile impact strength, flexural modulus of elasticity, Vicat Softening Temperature (VST), weld strength) due to dosage of inferior grades of raw material.
NEED FOR WINDOW LABELLING Taking Europe and US window labelling as a benchmark will be a great idea to improve consumer information in India, notes Hemjith A Vengateri. Probably, some adaptations will be necessary, but by following the main principles, window performance labelling is something definitely feasible in the near future. Amit Klinger too agrees that labelling programme will certainly help customers choose quality window system, based on their budget. It will create more awareness among the end users and will result in overall improvement of quality and reliability across the region. So, the labelling programme is a must in a country like India, where literacy rate is very low with a wide variety of product offerings available in the market to choose from. Mario says that UDMA is going to introduce the window labelling programme shortly. “We are showcasing this proposal to architects across the country and based on the final feedback
A project with Alumil Supreme
we are going to start this rating system by mid-2018,” he adds. Höllrigl too agrees that it is a good idea for India to go for a labelling programme, but there are some concerns. The current difference between single glazing (glass U-value 5.8 W/m2K) and low-e double glazing (glass U-value 1.4 W/m2K) may become an insurmountable challenge, since the general public will want to purchase A rated products, i.e., the best which can only be achieved with gas filled double glazed units utilising warm edge, spacer bar technology. Alternatively, single glazed frames can be excluded from any future Indian rating schemes. Experience has shown that offering WER frames (Window Energy Rating, the UK) have raised the quality standard to achieve consistently better air tightness. Today, most UK fabricators offering WER frames have improved their manufacturing processes, upgraded components and provide two rating options as standard, A rating as the best and C rating mainly for cost effectiveness.
CONCLUSION Fenestration systems are essential elements of all buildings. As daylighting and ventilation devices, they are called upon to provide a wide range of performance attributes. In order to develop and utilise such systems successfully, it is advantageous to carefully and critically assess the desired performance attributes of “ideal” fenestration
The labelling programme helps in: 1. Selecting the right product for right performance for a given requirement. 2. Removes the confusion in quality and cost. 3. Eliminates over specification or under specification. 4. Helps in bypassing the technical jargon like ‘U’ Value, SHGC, VLT while purchasing. 5. Manufactures know what they are selling and educate customers what they are buying. 6. It becomes easier for inspecting authority. 7. The government has more control over the poor quality. 8. The builder can advertise and gain competitive edge over other. 9. Energy awareness will become easier.
systems. But the wide range of performance needed from the “ideal” fenestration system is not readily available to specifiers today. Emerging technology for dynamic, smart glazing has the potential to provide an important new set of functionality that promises to address several critical shortcomings of existing technology.

Ever since their inception in 1996, Morphogenesis has had a reputation of being an innovative practice at the forefront of thought leadership in design. They look at all aspects of the context and arrive at an innovative response to the physical, geographical and cultural conditions that address the user brief, and ultimately aspiration. They have done over 450 projects across India, Bangladesh, Nepal, Sri Lanka, South Africa and the UAE. The firm has over 130 professionals in Delhi and Bangalore offices. Recipient of over 80 international and national awards, the firm provides specialized services in distinct verticals like master planning, residential, commercial, workplace, institutional, hospitality, interiors and landscape designs, all with a strong backbone of ‘Green Design’ The distinguished architects, Manit Rastogi and Sonali Rastogi candidly spoke to WFM about their professional journey spanning 21 years, their innovative approach to working on sustainable buildings, their current projects, their future goals and design intentions, and much more.
Manit Rastogi & Sonali Rastogi Founder Partners, Morphogenesis
WFM: Tell us about your firm Morphogenesis and your journey as an architect?
Sonali Rastogi (SR): I come from a family of architects. My parents are architects and I am married to an architect (Manit Rastogi). We run the firm together. So for me, my entire life is an architectural sojourn. Our practice is now 21 years old.

Manit and I were students of SPA Delhi. Then we studied at the Architectural Association (AA), London. While we were at AA, we attended a number of design dialogues and discourses on architecture from around the world. We noticed that, in such events, there was a completely missing component of Indian architecture within the global perspective. We developed a deep desire to become a part of the architectural language which was being discussed

Pearl Academy - Simple cementacious Jali, which are often made on the road side, was used as a second skin to the entire building
world over, and also to showcase what would be an Indian architectural fit for today. With that kind of challenge and drive in our head, we returned to India to set up this practice called Morphogenesis in the year 1996, and it has been a phenomenal 21 years.
Manit Rastogi (MR): Our journey as a practice has been captured in our monograph ‘Morphogenesis | The Indian Perspective, The Global Context’ that we wrote to commemorate our 20 year anniversary. The process of compiling the book was significant and it allowed us to formally document and review our learnings over the past 20 years, consequently enabling us to even better define our vision, for the next 20.
WFM: Please tell us about your iconic projects?
MR: It is difficult for an architect to define ‘what is iconic’, when you look back and analyse the 21 years of our journey. Design for us is an outcome of a process of enquiry and a drive for innovation. So, for a person who is part of the creative process, it is very difficult to call something iconic or not iconic. But, I think for me, the Pearl Academy was iconic because it was one of our lowest cost projects, derived largely from vernacular architecture, which achieved a new benchmark in sustainability. Also it has visually caught the imagination of the world and has won many international awards. SR: To me, our first major project, Apollo Tyres Corporate Office, stands out as iconic, because the first is always very close to one’s heart. Currently we are doing the Zydus Corporate Office in Ahmedabad which is a very unusual looking project, made of a series of doubly curved walls. It is inspired from vernacular architecture of forts in the region, in its detail. But it has an inclusive global character, where its construction technology is very special and the design itself is a new learning experience. All these combined make the project an iconic one. WFM: One of your ongoing projects is totally net

The first major project, Apollo Tyres Corporate Office, stands out as iconic building
sustainable construction technologies and optimised use of materials, we bring down the energy consumption (measured by the Energy Performance Index or EPI) of a building to the lowest possible. We have managed to bring down the EPI of our buildings to as low as 25kWh/sqm/yr, which is more than 70% improvement over even Green benchmarks. It is then far more realistic to offset this reduced requirement by renewables, hence being as close to net-zero enabled as possible.
Another view - Apollo Tyres Corporate Office
SR: We have a lot of conversations among our team members. Morphogenesis is a believer in the collective. We always try to approach projects from a fresh perspective when a team is assigned a job. This is why, though we do work within a contemporary format, it is difficult to stereo type a Morphogenesis style or our projects. Each time we try to remove ourselves from defined, static aesthetics and approach the project afresh. WFM: According to you, what is a green building
The campus designed for Infosys Ltd., Nagpur would be a net zero on energy, water and waste discharge. It would push us towards delivering one of the world's most energy efficient buildings, and enabling the aim to build the world's most sustainable office building. WFM: Could you please tell me about your design approach?
MR: Design is a subjective process where how much ever one tries, approach is hard to define. But one of the approaches has been always to look at it from its first principles, for instance: What are the resources available at our hand? How can the project be more sustainable, not just in terms of energy, but considering sociocultural aspects too? The architecture should enable the local population in some way. It needs to be responsive to its context, yet not so deeply immersed in history that it cannot find a global position for itself.
78 WFM SEPT - OCT 2017
and what is a sustainable design? SR: When we started this practice 21 years ago, the concept of green building for a common man was the mud hut with terrace garden. The definition as it currently stands is that a green building is one with least possible energy consumption to construct and run that building. Sustainability depends on materials used- recycled or locally procured, etc. Green is about the total possibility of how you use the energy in the building and how little you consume. Green is not dependent on whether the building is high-rise or a low-rise, or a hut. MR: The most basic design principle for sustainability is to examine for the product that one intends to create. A project needs to be looked at as a problem at hand, and one has to find an apt solution which ought to be sustainable. I don’t believe that there is any single type of building or typology which cannot be looked upon in a sustainable way.

A project for Uppal Housing at Gurugram
WFM: Please explain some of your innovative approaches which you have considered for your highrise projects?
MR: One of the most innovative and simplest approaches that an architect can use is passive design techniques. I think the maximum environmental gain, hence innovation, can come out of building orientation and morphology. For example, in our climate, if we design all the glazing facing west and make it top to bottom glazing, then we are not being sustainable. Understanding and designing according to the orientation of the building, sun path and specifications like thermal value, U value, thermal lag, etc., which are the basic principles of building physics, are very important. Once an architect understands these specifications, and designs the building morphology to fit these specifications, then 50 percent of the energy problems are solved.
GYS Vision at Gurugram
SR: One challenge that needs addressing is looking at the cost of the project, not based on individual components or materials, but as a combination of materials. The challenge is to make people see the whole scheme as an integrated development. For example, the shading fins in the west and south of a building is not something which can be worked separately from its glass facade. But if we add a double skin façade, we cannot reduce the shading, neither can we go for cheaper or lesser quality glass somewhere else in the project. This is a major problem.
WFM: What are the greatest challenges that you
If you are designing in an integrated fashion for an overall performance index, you should not start taking out each object of the façade separately and calculate how much cost could be cut out of it. By doing so, the desired envelope design and its performance cannot be achieved. Moreover, we cannot achieve a façade that pushes the boundaries, both aesthetically and functionally.

WFM: Please describe the role of façade in building
sustainability? MR: I would say that, today we do not face any challenge. These days, people come looking for sustainable designs and technologies because they have understood that sustainable designs not only cut the construction cost and running cost, but it could be the USP for selling their product. I think, this issue was a major one, i.e., to understand what is sustainability, when we started our firm, not anymore.
SR: It is a difficult question. Façade plays the role of skin in human existence. How can I peel off the skin and expect the organs and other parts to exist in our body? Skin or the external surface of the human body is what people see. And it is through the skin that we imbibe and it needs to be designed well. A building is just like a living organism. As we breathe through the skin, a building also feels the heat, and connects SEPT - OCT 2017 WFM 81

with the exterior through its skin. It is an integral part of the project and one cannot and should not see it separately. I would say that the building skin or façade is the integral and most visible part of the building which casts the first aesthetic impression on a user, and is hence the identity of the building. WFM: What are the key factors which you would have considered while designing a sustainable urban façade?
WFM: How do you decide or choose the façade materials for any project?
SR: Selection of materials for the façade is mostly based on the aesthetics, performance, sustainability, etc. So, it is a subjective as well as an objective decision. Cost is a major factor which determines the choice of materials, along with durability and customisation. It also depends on the desired image and kind of receiving audience the client is doing the project for. WFM: Please tell us about the innovative technology and material which you have adopted in one or two of your recent projects?
MR: The key points are: 1. Knowing the building physics, which includes various scientific aspects like heat transfer, performance, etc. 2. Knowing and using software for computing heat ingress. 3. Knowing the position of the sun in the sky and the movement of the sun, and how the sun corresponds to the building skin. To understand the incidence of sun rays and decide on the opaque and transparent surfaces (where solar ingress should be allowed and where not). 4. Analysing materials for the skin in order to make it more functional- in terms of shading, recessing, heat protection, light gain, etc. 5. Understanding the angles of incidence and reflection, on heat and glare

SR: A perfect example would be the Zydus project, which we are doing in Ahmedabad, where we’re using Corten steel, concrete and traditional insulated glass blocks. The glass blocks and lighting together would create the desired sculptural façade. At this moment, we are most excited about this project. Materials used in the façade of another built project, Pearl Academy is poles apart from the Ahmedabad’s project. We have used simple cementacious Jali, which are often made on the road side.

trading hub, spread across approximate 36 acres. This upcoming bourse will accommodate over 4,000 offices of the diamond traders. At over 65 lakh Sq ft of built-up area, the Surat Diamond Bourse, will provide employment to 1.5 lakh people. The enormous size of the project brings its own set of challenges. In this project, the orientation is such that no direct sun hits the occupants. The façade must have an impactful entrance, being such an enormous and inspiring structure. It must provide a sense of pride. Façades have been kept opaque from the west side, so that there is no direct sun hit during any time of the day. The common areas and foyers are not air-conditioned. Temperature is controlled purely by ventilation.
Since the climatic zone is completely different, replicating the design from the western countries does not make sense, and the design will not work here in India if the patterns are followed blindly. However, if they merge their existing technical know-how with a response to the climatic and socio-cultural conditions here, they could end up with successful buildings. SR: It is not about Indian or foreign designers or designs, but is about the building physics, cultural needs of the people... all these aspects need to be looked into and the ones that understand these aspects and their inter-related dynamics, will design a successful building in India. But I am not a huge proponent of taking a blue glass tower from New York and building the same in Noida.
WFM: Your project for ITC is again very different
from SDB, could you talk about this project in Kolkata? SR: Yes, our project in Kolkata for ITC is completely different. It is a series of sets of smaller buildings. ITC is a project with a vertical morphology, whereas in SDB, the movement is mainly horizontal, having a very long morphology. The approach for the projects are also different. One exemplifies a building design approach while the other, due to its sheer scale, exemplifies an urban design approach.
WFM: What are the key quality control aspects to consider while designing and installing façades?
SR: Façade consultancy is a very large profession in this country. An uninitiated developer or a client does not understand the need of a façade consultant. In the case of glass façades, they may still look for or employ a façade consultant. But when it comes to other materials like stone, they ignore it. They incorrectly believe a façade consultant is not required 'just for sticking stones on the façade'.
WFM: Could you please brief us on a few factors
which you consider while designing and executing façades of high-rise buildings?

MR: The façade design approach for high-rise and low-rise buildings are completely different. The image ability desired, the architectural aspirations, the design process, the sustainability of products (the products that are used at different heights are different in nature), installation technologies, etc., are very different for a low-rise and high-rise project. Hence the approach is also very diverse. It is hard to describe the difference in the approaches and processes which cannot be compared. WFM: Most of the supertall buildings in India are designed by architects from the west and the consultants engaged are also from abroad, following different architectural language similar to the western countries. What is your opinion on this?
MR: Design should vary according to climatic condition and geographical location of a project.

floor space to be naturally day lit. Besides the façade, you typically cannot get light to penetrate more than 8 to 9 meters from a façade. Therefore the best solution is not to make buildings wider than 18 meters. If you make it wider, incorporate those functions in the middle which do not require daylight. It is not just the function of façade alone, it is the question on the morphology of the building as well, i.e., the shape of the building, where by the façade will play its role in letting the daylight in.

understand and realize the importance of façade consultants. High-rise in India is a new typology too, which needs to mature a lot more. People are still learning the specifics of the typology. But I am sure that we will quickly gain the knowledge with the growth of the industry, which is happening at a very rapid pace. WFM: Do you think that the contractors have got upper hands in many projects in India and architects have to alter their design based on the contractor's cost cutting ways?
MR: The shading depends on the cost and the aesthetics. Also, you can use horizontal or vertical shading. All that is dependent on the design and the orientation of the building as well as occupant needs and energy targets set. WFM: Could you please throw some light on your future projects, goals, some of the design intentions, and projects which you would like to do in future?
SR: What this country lacks is public buildings like museums and such allied infrastructure. For example, buildings like the Calatrava designed station at Ground Zero in New York. We need such remarkable pieces of architecture. I look forward to this country investing more in public architecture, and we would wish to play a role in how that evolves.
SR: I totally disagree with it. WFM: What is your advice to young architects who
We ensure that project cost and its documentation is in place before the contractor comes on board. The contractor is only there to execute what is on the drawing board. If correctly done, it is supposed to give the bill of quantities and costs. The contractor has nothing to do with the cost. It is a shoddy way of working, where one has half-baked design and the client then depends on the contractor’s input for cost. The only way a contractor gets involved in these kind of decisions is when the design and documentation of architecture and engineering is not complete.
are just starting their practice? SR: I strongly believe that if you don’t have the vision for your future goals, then you might as well do any job. Why specifically the art of an architect? It is a hard job. It does not pay that much. Then why do it. If you are intending to take up the job of an architect, you must have the vision and passion to take it forward. Our philosophy in life as far as work and the profession is concerned, is that architecture & design is a way of life, and it calls for a lifetime of commitment and conviction.

VERTICALLY STACKED MODULES Infosys Campus MIHAN, Nagpur
The design of the Infosys office complex (Nagpur, India)
Infosys Campus MIHAN is located in Nagpur, and sits in a ‘Special Economic Zone- SEZ’. Special Economic Zones are designated areas that possess special fiscal regulations different from the rest of the land with the aim of easing international trade and being conducive to foreign direct investment. The client brief was simply ‘to create the world’s most sustainable office building’. Morphogenesis took this opportunity to test if a development of this scale could be net zero on water, energy and waste to landfill, with a future aim to develop a model for sustainable master-planning for larger sites. The geology of the land played a key role in the morphological evolution; Nagpur lies in seismic zone II and the soil has a high bearing capacity. The building modules or tubes, are largely column free spaces that are stacked into a four floor format and are vertically
connected through an atrium and a staircase. Each tube is swung at an angle of ± 22.5 degrees, this rotation in the stacking structure generates new ground at elevated levels. This dynamic morphology was a direct outcome of low seismic activity and the hydro-geological nature of the area. The introduction of an earth sheltered, shaded and passively cooled landscape at a subterranean level integrates the different building blocks with the subterranean pedestrian circulation system. This is flanked with food courts and other public activities. These lowlying congregation spaces are shaded by the buildings on top and are thermally buffered by the surrounding land. This results in a large amount of public space being independent of mechanical cooling systems. The plan evolved from the notion of understanding the capacity of the site; a capacity determined by functions like energy, water, geology of the land, SEPT - OCT 2017 WFM 87

along with essential rules of urban design pertaining to light, ventilation, and shading. Based on this a master-plan for a working population of 20,000 emerged, which is net zero on energy, water and waste discharge. Radial planning is used, in response to the natural topographical condition and the Western, North-Western and South-Western wind directions specific to the region. This radial grid strategy aids in bringing down the perceivable temperatures and creating a micro climate on site. The ± 22.5 degrees North orientation stems from Nagpur’s location on the Tropic of Cancer; this allows for 90 percent of the building to be day lit. Sixteen metre wide floor plates, solar protection strategies like façade shielding with fins, and mutual shading, proved to be an effective solution to ensure the building blocks are uniformly day-lit and completely glare-free.
overall 600mm c/c proved to be optimum for North, North West facing windows. Solar controls for south façades were designed considering 21st December (winter solstice) for peak design parameters because the sun drops down to the lowest altitude levels (0.6° at 5.30pm). Here, the solar altitude was identified as the critical angle. It is important to highlight that Nagpur tends to see mostly clear sunny skies and so the tendency of experiencing glare is quite high. A solution for this was to obstruct the bright sky view from the upper end of the window. Consequently, the window was divided in 2 equal parts - daylight window at 2.1m and vision window at sill level of 1.1m. While designing for the South, South-East windows, it was observed that vertical fins of depth and spacing of
The design of the built envelope was governed by the following parameters, such as solar control, glare control, distribution of daylight and heat loads. Solar Control: Solar shading design for a typical opening on each of the four orientations (NNW-SSE and NNE-SSW) was carried out. After calculations, it was concluded that 422mm deep vertical fins spaced at 600mm c/c could be adopted for North and NorthEast orientation as this solution helped maintain views across the entire height of the window while effectively shading the morning sun. Following the same methodology, 600mm wide fins spaced at an

600mm were effective for obstructing the sun after 11am till 5.30pm. Horizontal overhangs were explored for providing shade for the remaining morning period. The role of the shading devices was reversed for the south, south-west window where the vertical fins were effective from 9am to 11am and overhang helped distance the direct sun from the workstation. Daylight Distribution and Glare Control: South facing windows suffer more from direct solar radiation for most part of the day. Despite frosting the daylight panel, the high levels of external illuminance could lead to the panel itself becoming extremely bright. This aspect was countered through light shelves at 2500mm which obstructed the direct view of the daylight panel from the occupant’s seated level. For northern orientations, the daylight available is diffused and therefore glare-free. This fact was exploited by the addition of internal light shelves on the northern façades which were expected to increase daylight distribution inside the workspace. Further extending the light shelves by another 600mm towards the outside led to a significant improvement in the daylight levels.
EPI Index of Infosys, Nagpur

Thermal Efficiency: The heat gain process through opaque elements like walls and slabs of a building mainly comprises heat gain through conduction. Transparent building elements, on the other hand, have higher vulnerability to heat gain through solar radiation in addition to conductive heat gain. Heat gain from solar radiation is based on the solar heat gain factor (SHGC) of the glass which, in turn, depends on the specifications of the glass and on the angle of incidence. Owing to the solar shading design, the effective SHGC in this case was much lower than the maximum SHGC which played a significant role in reducing the overall heat gain from incident solar radiation. Finally, the solar heat gain for the entire building was calculated and resulted in an overall thermal efficiency of 0.79W/sq.ft. The use of passive strategies though the project aids in reducing energy requirements to one fifth of the consumption of a typical office. This reduced requirement is serviced by a 30 acre on-site solar plant, resulting in zero energy from the grid. Zero water dependence is achieved by creating a reservoir on site. Designed as a lake adjoining the existing water-tank in the West, this reservoir is fed by effective rainwater surface run-offs. Efficient system design ensures water management and the recycling methods reduce the water consumption by half. Bio-degradable waste disposal is addressed by a bio-gas plant and vermicomposting.

of international finance institution like Lehmann brothers and there were a lot of uncertainties in the market. The demand from the industry was very low. It was probably a good opportunity for us to come in at the time, so the architects had more time and we could engage with them and we could look for some reference projects. The drawback was that the architects were not open to receiving world class products, especially the premium material. We took that as a challenge and started working on a few reference projects. The sustainability of these projects opened up opportunities for our products, especially for an exterior product. The industry started noticing the products and we started getting more and more opportunities. Today we can proudly say that our architectural products are widely accepted. WFM: How good was the response over the years?
PR: Response was poor to start with, but over the period of time, it got better and better and today we are well received in the industry. Today, while meeting an architect, he/she has a far friendlier approach. They receive us very well and many a times, architects are very happy to know about our products because they are looking for world-class product like ours. The interaction is more from products to the possibilities of various applications & to deal with complex façade designs.

PR: From the product point of view, we have always been into exterior products. But yes, what has changed in the decades is that we launched a new collection two years back. Today we are proud to say that we have over 30,000 SKUs which we are offering to the market. In the whole process of the journey, it’s not only the products, we have scaled up on application capabilities too. We deal with complex facades, and are able to provide design support. We are also able to handle large projects. Our partners are well trained and toned, and they are able to scale up. WFM: What are the factors which inspired you to

WFM: Could you please tell us about the advantages of using FunderMax cladding as an exterior product?
PR: Firstly, it is a world class product with the best of quality and sustainability. Secondly, we also do a ventilated façade system which is also quite unique to India. It is very good for the thermal insulation of the building, making it an energy efficient façade. Overall, it is a sustainable product as well as the installation supports it for the overall efficiency of the building and in the process, enhancing the life of the building protecting it from all external weather conditions. WFM: How does the product help in improving the aesthetics of the building?
PR: For any application, worldwide, the basic purpose of cladding is more functional rather than aesthetic. So, first of all what is important is functional requirement and then the functional requirement would be supported by good aesthetic looking material. Overall, we were able to deliver sustainable façades for the building. And more importantly, we are able to give a character to the building in terms of the vibrant facades that we offer.

PR: Façade market in India is still largely an unorganised one. I would say that 2/3rd of the market is still an unorganised sector. With events like ZAK World of Façades and a number of other organized engagements within the industry, we see a transformation happening and the share of organised market is growing year by year. It is still a large market with a huge potential. There is space for every organised player.
PR: This was a very good decision which has happened to our industry. Every organised player will benefit from this and such development gives an opportunity for people to move from the unorganised sector to a more organised sector. Such acts protect the consumer interests which are of paramount importance to the suppliers. We are in favour and support the RERA.

successful have your products been? And how have you been able to optimise your sales in India with this constraint of cost sensitive market? PR: We definitely acknowledge that India is a price sensitive country and within India there are markets which are more price sensitive, like markets in the East. Within this large market, there are many valuable customers who want to use the world class products, best of services and this contributes to a significant share. As long as we are able to connect to the customer and show them the benefits which go beyond just the features, we are able to gain from here. If you want to add a skin to the building and if we do the cladding, it would surely enhance the life of the building. As long as we are able to deliver those benefits and values, the price is a discussion we can certainly address. It is true that we still have to respect the pyramid and focus on the top segment of the pyramid which is still a big market. WFM: What are the key aspects to be considered
while going for a cladding material? PR: The sustainability of the material is very important. The facades should be living and breathing skins.

Today, we are already looking into laboratory business, we are talking about cubicle business and we are also looking for opportunities in the kitchen furniture. We are exploring within the portfolio of what we have. Therefore, we don’t have to go beyond our product range to partner with anyone else with the products at least. But within our product portfolio and existing partner work, under our network of what we have, we have lots of opportunities to scale up our business. WFM: What is your take on Façade Safety?
PR: Well, we think the hot topics today is the recent fire accidents that have happened in London and Dubai. Looking at the projects in India, façade safety is the area where the industry should really grow and truly work towards maximum safety. We should not wait for the accidents to happen and then work out for solutions. The industry should work together to strengthen our National Building Code so that our buildings are safe in the first place and able to handle any unfortunate fire accidents. FunderMax products have flame retardant as well as fire retardant features, which can contribute to the

safety of the buildings. We are definitely working with the other leaders of the industry to make the buildings safer. This is one area, where I think the industry should be quite proactive in their approach. At this moment, we are thankful to the industry with whom we have been able to work with and the opportunities that it has provided and we would like to continue partnering with the industry.

A VIVID FAÇADE SWATHED IN A RIOT OF COLOURS Hotel Aira, Vijaywada, Andhra Pradesh
Aira is a boutique hotel with forty guest rooms spread over five floors located in the commercial heart of Vijayawada, Andhra Pradesh. With many concrete structures around, the hotel wasn’t getting the prominence it deserved. The client wanted the hotel to stand out visually. To address this issue, the designer, Shankar Narayan Architects, created a layer of colourful panels over the building façade. It was a visual element that would be memorable and longlasting. The Challenge: One major factor that the architect considered before starting the renovation was the harsh sunlight of Vijayawada. Some of the primary challenges in panel formation were: • Ensuring free movement of air through the panels and at the same time allowing privacy in the road facing rooms. • Providing shade to the hotel’s façade
• Creating a dynamic effect by allowing gentle movement of the panels and yet making sure the structure is strong. The Solution: Shankar Narayan Architects developed an elaborate plan that ticked off all the project requirements and the associated challenges. It facilitated aesthetic appeal, all-weather resistance and functional results. The project panned out on the following lines: • Colour transition: The colour layout was planned in a manner to reveal the transition from blue (representing water) on the north east side and orange (representing sun) on the south east side. • Optimal usage of materials: Square panels of optimum sizes were riveted to stainless steel wire rope cables pulled between two MS box section frames forty feet apart in elevation. • Dynamic effect: Creating a moving effect in such SEPT - OCT 2017 WFM 107
a way that the panels swayed slightly along with the breeze, but rotation was avoided through interconnection of the panels. Airflow: The panels were perforated with creative patterns to enable smooth air flow and give a light and shade effect to the building.
FunderMax Composite Laminate panels were chosen for the following reasons: • Light weight, weather proof, flame retardant and unbreakable • Available in a range of colours and thicknesses • Non fading, bright, unicolour decor range • Easy to cut and perforate without the risk of delamination • Easily replaceable in case of need The Result: The new creative and unique facade resulted in an uptick in brand recognition of hotel Aira and consequently, guest inflow. It was an exciting culmination of team work - a bold client and creative architectural vision that was brought to life by FunderMax. The Architect: Shankar Narayan Architects is one of the most respected and recognized architectural firms in Hyderabad. For over quarter of a century, the firm has worked on a wide spectrum of projects including a railway station, campuses, institutional, industrial and corporate interiors, independent residences and even an animal shelter for an NGO. The practice, headed by Mr. G. Shankar Narayan is known for its innovative design approach, costeffective construction techniques, professionalism and financial integrity. The firm relies on the fundamentals of space, proportion, light and an
honest use of materials to create a sense of belonging for the occupant.

Detailing of the sandwiched insulated panels for the façade
Initially, the architects planned to use steel for the insulation panels, but later settled for ACP since it fares better in coastal climate than steel. Owing to its lightweight, ACP has an added advantage over other building materials used for cladding. There is a host of economic benefits of building insulation. A few of them are as follows: 70% to 80% energy loss is through façade. Hence insulated façades will save up energy consumption and eventually result in lower electricity bills Insulation reduces the heating and cooling costs by 20% to 30% Cost of insulation is not more than 1% to 3% of the total property value and lasts life long without any maintenance. Building insulation has got environmental benefits too. Energy consumption in building segment is rising at a faster rate due to rapid urbanization. In India, buildings account for 10% of total greenhouse gas emission. Insulation has immediate impact

The circulation spine within the office skirts the perimeter of the open courtyard with a shallow pool of water
Retaining the architect’s signature sculptural presence in his design and form, the office is built completely in a steel frame structure. Corten steel is used for the external face of the building and galvanized metal for the roof considering its sturdiness and longevity it provides to the structure. The architect chose the material consciously as it enable the façade to withstand the ravages of time and other external elements. Besides, the material ages with grace and beauty in a natural process. The striking orange colour of the material brings attention to the structure easily. In fact, it carves a distinct personality of the structure. The circulation spine within the office skirts the perimeter of the open courtyard with a shallow pool of water reflecting the surrounding buildings. The courtyard allows its users to experience the outdoor space while moving within the office. Near the site is a large nine-storeyed building under construction, close to the southern side of the office. A small garden space is created between the two larger office cabins that acts as a buffer. In addition, each of the internal spaces is lit by north facing openings created by splitting the curvilinear form into a series of sequential spaces based upon the needs of the office. The orientation of the office ensures that each part of the office derives indirect north light, thus increasing the energy efficiency of the spaces within due to the reduced heat gain from the south. Simultaneously,
118 WFM SEPT - OCT 2017
the design ensures that no part of the office looks towards the large dominating built structure on the southern side. The building height varies from 9m on the north facing side to 4m on the southern side with the roof gradually stepping down. Ventilators within the roofs varying heights allow natural light to additionally penetrate the internal spaces. The water pool within the courtyard helps reduce the temperatures further due to evaporative cooling. The internal spaces of this small building are expressed externally as well as volumetrically. The most challenging aspect of this project was to complete the building within a specific time frame. The architect completed the building in three months before the strict deadline.

landmarks that inspire the development of the urban fabric around them. The museum’s architecture and experience design has not been envisioned to be mere repositories of frozen moments of the past, but designed with the intention of making it alive and active participant in the contemporary dynamics of the historic city of Lucknow. The external façade strives to achieve fitting, sensitive and gallant negotiations with the contrasting and oft conflicting contexts of urbanity and nature. The terracotta cladding responds to the integrity of a historic cityscape. The blank walls of the simplified triangle are born out of the need for the museum’s introverted character, but belie the complexity of interlocking volumes and themes that make for the museum journey.
The building with its clean and clear lines is deceptively simple
to construct in concrete. However, its terracotta cladding throws light on its desire to cohabit- it’s warm, earthy and deep texture is very indigenous. This formal asceticism in the use of stark and simple material strives to imbue richness and nobility. The material choice conveys a certain timelessness and ease of maintenance, both elements much needed for a public space of this nature. The presence of a ‘skin’ as opposed to a façade means that the building sports a layered outer covering. The custom-designed terracotta tiles are dry-clad with an air-gap between this layer and the true wall. ©Andre j fanthome

The monolithic and bold form of the building exudes empowerment. Just like the man it represents, the building with its clean and clear lines is deceptively simple, the profound depth and complexity revealed on the inside and it only reinforces the notion of simplicity being rooted in deep thought and reflection. The austere expression of materials, subconsciously echoes the honest and unpretentious character of JP while the grand form makes a bold architectural impression that is absolutely imperative and intentional, meant to push people towards questioning fundamentals and towards brave expressions in the pursuit of change.

This space filled with rock wool offers a measurable degree of thermal and sound insulation. While the former keeps the much visited place cool and comfortable, the latter helps in cutting down the city cacophony, along with a host of other measures and enables the immersive museum experience to be smooth and undisrupted by noise. Further, the terracotta tiles being perforated, allow for air flow and ventilation. The use of this indigenous and earthfriendly material states the museum’s ecological positioning. The triangular shape of the façade best diagrammatically represents the triad of objectives of socialism as conceived by JP- freedom, equality and brotherhood. Three of these words are celebrated and etched in multiple languages on the terracotta panels, bearing testimony to JP’s national outreach and following.

Interestingly the triangular façade facing the convention centre, sports a viewing tunnel from which the monumental building is clearly viewed.

The façade of the CMC Showroom
124 WFM SEPT - OCT 2017
Classic Marble Company’s (CMC) head office cum showroom has been designed to represent distinction with innovation. Breaking away from the clutter,
the showroom cum office building adds a spark to the immediate area with its façade telling the story of the brand even before anyone steps foot in it. The façade gives the first impression of a structure and reflects the identity of the building. This required for the façade to not only look different but also to endorse the company’s product. Kalinga Stone, CMC’s flagship brand for composites, was picked out for accomplishing this objective and the entire façade was clad with the marble. The next step was to further accentuate the beauty of the façade by adding to it an element of light. Interestingly, being a processed material which makes it stronger, the marble allowed for being machined into reduced thickness. Without making it dangerously fragile, but thin enough for making it translucent, the marble slabs were machined to 5 mm thickness in select areas. A technical innovation in external façades and a first of its kind in India, a CNC machine was employed to cut or engrave square patterns into the marble slab. The resulting opaque surface allows for light to pass through it, beautifully highlighting the delicate veins and elaborating the richness of the marble. In the daytime, the curtain filters the light through it, which falls inside the office interiors in a gorgeous mélange of colours and designs, and in the evenings, the LEDs behind the reliefs light up the façade to render an expression reminiscent of twinkling stars in a Milky Way.
to maximize on its usage. The floors, table tops, counters, etc., are made using the in-house material. The walls used huge slabs of marble that reflect a character like that of a painting. It’s an instant suggestion of its potential. The mural at the entrance and reception table are the highlight of the interiors. Carved out of a single piece of raw block of quarry marble, they sit like two majestic pieces in the lobby, complemented with a modular light chandelier in a three-dimensional form hanging over the reception almost imitating a tree branch that hangs over the solid rock. The architects tried to keep the furniture minimal and the lighting scheme around is only to highlight the marble on walls and floor for the best. The architects also planned a cafe corner along a discussion area. It lends a space and time to the visitor to immerse themselves into the surrounding lifestyle. The punch
The façade design not only marks an identity, but also proposes the way for new façades to spring up. With these elements of modernism, innovation and endurance, it is an easy trend setter and proposes a wide usage in the corporate and luxury sector. This encourages them to use it wherever creativity is prime against affordability. Where the interiors of the showroom are concerned, the architects conceptualized the space as a modern day museum with an understated cover that is effective enough to display the products like paintings in a museum. Their range of stones varied in colours, the architects chose neutral shades of grey and brown for the walls. The circulation was planned to create dark tunnels with a bright streak of flexi light that marks the outline of these tunnels and adjustable art light highlighting only the marbles on both sides. When you design a showroom for a product so widely used in the construction industry, you have

Svelto Lounge is another highlight corner where the high pressure laminates have been used to create a three-dimensional feature. The play of light is an interesting detail where the surface undulations create dynamic patterns with slim linear profiles. The showroom is a representative of trade that throws creative ideas for its inherent material and creative lighting. The reception carved out of a single boulder of marble

being sturdy and extremely durable. The innovative R&D department of ALUMIL, developed a tailor made version of the excellent casement window SUPREME S91, which is specially designed for passive houses. A customized solution of this particular window was chosen by Google Inc. In total, 3,500 windows were fabricated for the successful renovation of Google’s fenestration at its central offices in New York.

Google wanted to improve the aesthetic value and the energy efficiency of its offices in New York at the 111 Eighth Avenue, one of the largest buildings in town. During the renovation, they needed a window that would incorporate the essential sustainable and energy efficient characteristics, while simultaneously

The product was specially designed in order to meet the high requirements of passive houses (certified by the German Passive House Institute). It is ideal for heavy duty, insulated casement windows with high security level. The system is characterized for its excellent performance in terms of thermal insulation, water tightness and noise reduction as well as for its flexibility and ease of fabrication. Passive buildings are the future of the construction industry, as the need for low-energy buildings is increasing, not only for the sake of energy efficiency, but also because of the importance of minimizing

pollution. Based on studies, building energy consumption represents approximately 40% of the total energy consumed worldwide. It all started in March 2012 when it was informed about the specifications of a major project for the American tech giant Google Inc. The windows for the project, according to the specifications, required a coefficient of thermal transmittance Uw = 0.57 W/m2K, i.e. very high-insulation windows. Through its advanced window, the company proposed even higher thermal insulation with a thermal transmission coefficient of Uw = 0.55 W/m2K.

of energy consumed on transportation (per kg of produced material), the percentage of recycled materials used and the energy resources used by its plants (the plant mainly uses natural gas, but also solar energy). Finally, after some adjustments regarding cross sections by the architects of the project, the window reached its final shape. In order to confirm the final design, all the required performance tests took place in the company’s testing chamber and later on in the U.S., with strict tests regarding airtightness, water tightness, wind load resistance and design load.
Soon a prototype window was presented (October 2012). ALUMIL was quick to make a proposal at the requested thermal insulation (even slightly lower than the needed specifications). However, since no other company was able to make a proposal according to these demanding specifications, the architectural office realized that it should lower the insulation requirements and increase the UW value to 1,14 W/m2K in order to take more offers.
The product demonstrating high speed and flexibility, in combination with high-quality production based on “green processes” with top European standards, obviously earned Google’s trust from the beginning. Consequently, by achieving the wanted performance level, ALUMIL’s proposal was accepted and selected as a supplier for Google’s office windows in New York.
In January 2013, the company presented its second proposal according to the new specifications. The construction of the prototype window was arranged immediately, including additionally exterior blinds with aerodynamic design and internal shading curtains of high-functionality. The window was installed at the agreed time for evaluation.

INDIA’S FIRST 3D FINISH ACP GETS A MAGNUM VERSION Aludecor’s Cortina Series, the first 3D finish ACP series in India, now has a wider range. After a thorough market research, the company has recently introduced Cortina Magnum which has much wider stripes and is tailor made for exterior use.
Cortina is perfect to liven up both interiors and exteriors. While its usage in the exteriors changes the overall get-up of the building, lending a contemporary look to it, Cortina in the interiors adds a new dimension to the living
spaces. Creative arrangement of highlight, midtones and shadow adds a new dimension of depth to the design, creating a brilliant 3D effect. Cortina can also be made fire retardant.
Industry requirement for a cladding material with a path breaking design was long due. Hence, when Aludecor introduced Cortina in 2016, the industry was quick to lap it up. Industry experts have always held Cortina in very high regard ever since the day it was launched and felt it had a huge scope.
