SUSTAINABILITY– A Mass Movement

The enormous economic and population growth worldwide over the last four decades have together driven the impacts that threaten the health and well-being of our communities and nations. To name a few - ozone depletion, climate change, fouling of natural resources, and extensive loss of biodiversity and habitat.

Amidst this, one word that drives all activities across the globe in today’s time and age is Sustainability. Ranging from eco-systems to buildings, from commercial buildings to urban habitats, you name it and it strives to be sustainable. Leaders in business, government, academia, public-interest organizations, and communities are responding with innovative new solutions to sustainability. Large corporations, as well as small businesses are progressing beyond simple regulatory compliance in favor of more proactive roles in finding solutions to sustainability issues. The Indian building and construction industry is not far behind in this run for the cause. “For most urban projects, there are design charettes where sustainability consultant, structural consultant, architect and client get together and lay down the blueprint for the building which is conceived to be the epitome of sustainable methods and processes”, says Mr. KR Suresh, Regional Director, Axis Façade

Each component of a building contributes in achieving the much sought after sustainability and so does the building envelop. The building skin affects both the appearance and performance of a building like no other building system. Façade and fenestration in a building are thus of paramount importance when considering issues of green building and sustainable design.

WFM conducted a survey where they asked the general public or end user, what they understand by sustainability. Following pie chart describes their views: (Fig1)

The results of the survey are as follows:

58% of the respondents feel sustainability corresponds to Energy Efficiency

20% believe it’s no more than a marketing gimmick

8% of the respondents have no idea as to what sustainability actually means


14% agree that Sustainability is the essence of Social, Economic and Environmental viability – also described as three pillars of sustainability.

(The respondents comprise of the internet users who choose to participate in the poll only and not the general public)

There are a number of design drivers that account for developing and executing a high performance, sustainable façade vis-à-vis

water – [rain, humidity, condensation],

Air – [wind, ventilation],

Sound – [desired, undesired],

Light – [Sunlight, artificial],

View – [Public & Private],

heat – [solar radiation, air temperature],

fire – [flames, heat, smoke],

Pollution, security, safety, explosions etc.

A sustainable façade is the one which considers all these and still does not imbalance the environment, social equity and economic viability in the long run.

There are various ways to enhance environmental gains and make a façade sustainable, ranging from low cost passive systems to phenomenally expensive dynamic ones.

Passive methods

Optimized form/orientation – where building’s axis is aligned after analyzing the sun path diagram for that specific zone and the façade is angled to a certain degree so as to minimize the heat gain.

Natural ventilation.

Solar shading through basicstructural shading ornaments on the envelop.

Maximize day lighting at the same time minimizing glare.

Evaporative cooling and thermal banking.

Strategically planted trees for window shading and roof plantation etc.

Technological intervention:

“These are one time smart moves taken in order to enhance building performance by selecting the high performance façade components and technologies and integrating them to the building design”, – says Sharanjit Singh, Chairman, GSC Glass

High performance insulated glazing – with especially selective low-E glass.

Double skin façade – this emergent technology is

sustainability and what measures do they take to ensure that the window system or façade of their building will positively contribute in making their building eternally sustainable. We got various interesting responses:

Excerpts:-

“Sustainability has become much more relevant now with increase in sheer scale of the projects with the advent of various options available today.” says Architect Raman Sikka of Sikka Associates. As per him, good planning was the key 15 years back and now as well. Now it’s being demanded that the building is sustainable, envelop is energy efficient. For instance in the commonwealth games village all the residential high-rises were specified to be GRIHA rated. The windows for each of them were designed considering the same.

“Strategizing the whole process properly and doing the right things at the right time and the right place is the key to the whole sustainable story.”says Architect Alok Kumar, Chief Architect, DLF Limited

Vasudevan D, CEO, Chintels reiterates that “depending on the market conditions and demands,

they incorporate sustainable development practices.”Their residential development – International City in Gurgaon, which is a joint venture with Sobha is one such example.

Kangkan Chakraborty, President - Projects, Vatika Group, which was responsible for changing the face of NCR, maintains that they go an extra mile while designing and specifying engineered façade for their commercial buildings

“Sustainability goes beyond thermal efficiency. The building has to be viable; every building is different and has its own sustainability requirements. Orientation, location, application of the building, comfort of the occupants – all these have to be considered, new innovations to be devised and tested in order to validate it. The façade needs to be evaluated on all aspects – comfort level, energy, orientation, day lighting, heat island effect and overall running and maintenance cycles and should eventually minimize the cost of running the building. Then only it can be deemed sustainable ”says KR Suresh.

building projects where the attributes of transparent facades are desired the performance of the building skin is paramount. These sophisticated facade designs can compensate for the inherently poor insulating properties of glass. In addition to providing a thermal barrier, the systems can also provide an effective means of ventilation, and often involve shading devices for the control of solar penetration and glare

BIPV - Building-integrated photo-voltaic (BIPV) is an increasingly popular approach for using the building skin as a means to harvest solar energy

Dynamic Methods:

Heat Recovery Equipment

Sensors and Actuators – that respond to conditions like fire, smoke and inhabitation or lack of it

Responsive shading – dynamic louvers, photochromic shading devices which respond to position of solar position and help in light shelving as well to enable penetration of sunlight deep into the building

A sustainable façade helps in reduced consumption of resources and lowers the carbon footprint of the buildings.

WFM confronted leading stakeholders from the industry ranging from architects, developers, consultants and so on, asked them how they perceive

“The façade needs to be evaluated on all aspects – comfort level, energy, orientation, day lighting, heat island effect and overall running and maintenance cycles”KR Suresh, Regional Director, Axis Facades


finding increased application in

To all these views there was a counter view which is worth mentioning here:

The most sustainable building is one without windows. We are creating a problem and then we are solving it by creating more sustainable windows and façade. The most sustainable place to live in is a cave. But at the same time windows and façade bring in much needed air and light. There is a symbolic modern-ness about glass façades. So the need of the times is to design them so that they don’t pose a threat to our already depleting resources. Most important thing is to design windows where they matter. “For Indian climate having windows on the north façade makes sense. Having windows on the west doesn’t make sense. Use of DGUs wherever required, specialty films etc. are the measures worth considering and adopting” says Architect Gopinath Akalkotkar, Managing Leader, Statec Consultants.

In words of Mahesh Arumugam, Director, Meinhardt Façade “façade is an element that interacts with all other elements of a building. It acts as a skin between interior and exterior. It

has to be designed in sustainable way so as to allow maximum natural ventilation and natural lighting. A building Façade is normally designed for minimum of 25 years and aiming up to 50 years. All recyclable material should be used – aluminium, glass. The chemicals and coatings should be VOC free and should blend with natural environment. The design should keep in view the maintenance requirements that will come up in the lifespan of the façade vis-à-vis cleaning, repair for the normal wear and tear etc”

Thus we see sustainability is not just a myth or a marketing gimmick. There have been various qualitative researches that have identified that sustainable practices by the firms have in turn provided a few financial benefits to them in the long run. Environmental performance produces financial gain to the

building subsequently.

A lot has changed in past decade in India – the client is more aware, the industry has evolved, but as the basic rule of physics say – ideal can’t be achieved. There are design challenges, conflicting requirements, quality cost and time balancing, problems with implementing and even if all this goes well there are performance inefficiencies. It is a long path to be treaded on.

THE GREEN REVOLUTION

Tall buildings are getting greener. Or green buildings are getting taller. Either way you slice it, the sustainability movement in the world has gone large-scale and skyward, and nowhere is this more apparent than in Mumbai or in other metro cities of India.

By the end of this decade, several green high-rises vis-à-vis apartment buildings, office towers for a financial institution which are now being planned or are under construction will pepper the skyline.

Why the surge? Owners and developers say they’ve discussed green design for years, but no one wanted to be the first to take the plunge.

Within a year’s time from 1999 to 2000, environmental guidelines for construction were

passed, and the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) certification program was established. Those events changed everything. Before that, no one used to bother. No one understood green design or what its advantages were. But LEED gave us a blueprint for understanding how to get there, how to scale the heights of new Green Mantra.

The projects that are currently underway involve committed clients who hire architects capable of leading multidisciplinary and often international teams through the confusing choreography of standards, guidelines, and best practices for sustainable design. Though the technologies and strategies they employ aren’t always new, as the vernacular or building ideologies of some of the great masters, many are rare in tall buildings, a situation that will change as more cities embrace density and draft their own sustainability principles.

When our practice was chosen as the winning team for many a new projects in Mumbai, Pune and Bangalore, the critics swooned over facades of ultra-clear glass shaded by a scrim of white ceramics. In late 2002, lighting consultants and interior architects were already evaluating lighting and shading systems. So began a one-of-a-kind research project. The design team as an aspiration met with researchers, who recommended an integrated facade management system of dimmable lights and mechanized shades that would respond to the sun’s angle and intensity.

The zones and control schemes were tweaked continually as data were collected. We didn’t want fixtures going on and off, or shades going up and down constantly, Mechanical means are inundated to limits of operational time spans. The study showed that enough daylight penetrated the 44-foot

perimeter zone of the building to permit lights in that area to be dimmed, if not turned off entirely, and lighting energy savings in winter ranged from 10 to 70 percent. The design team issued solicitations based on detailed performance specifications written during the study.

THE EFFICIENCY THOUGHTBANK

The European architects have turned to double-walled glazing systems for efficiency. Such a system wouldn’t have worked here because of hot, humid summers. Still various methods partake in realizing an efficient building façade:

One “face” of the building, which looks towards South, is preferred and designed to be double-glazed to prevent heat gain.

Floor-to-ceiling glass is fritted at the top and bottom for interior comfort but left clear in the middle to preserve views.

A variety of energy-saving technologies are planned, including an onsite 4.6-megawatt cogeneration system, geothermal heating and cooling etc.

Building-integrated photovoltaic installed in three places—atop a glass roof that floats over the entrance, along the entry pavilion, and on spandrels that support a 10-story notch on the facade.

“You use a glass mirror to see your face; you use works of art to see your soul”

- George Bernard Shaw


Although it won’t produce large amounts of electricity, we use BIPVs near the ground so that people could see them and learn the importance of renewable energy.

Until not long ago, the architects and owners really led the process, but now we’re used to teaming up with engineers and consultants from the beginning of planning stage.

In the process of aspiring for sustainable design practices, we challenge ourselves to make the best use of everything that’s available for free. For instance air, sunlight, rainfall. Amongst our most innovative endeavors for a sustainable design includes a one-acre planted roof on the podium and an air filtration system that removes 95 percent of particulates, compared to 35 percent for most buildings.

SETTING THE BENCHMARK – OUR OWN GREEN BUILDING

Buildings have such a huge impact on the

environment and health, so having our own green building was a way to recognize this and to put our employees first.

People don’t interview for a job and wonder, ‘What’s the air quality like in here?’ But when they’re looking for an apartment, they want clean air; clean water and they’ll pay extra for those amenities. Rents in these buildings are anywhere between 10 to 20 percent higher than the conventional buildings.

CHALLENGES AND THE WAYS AROUND

Accolades aside, the true test of sustainability begins when the dust starts settling on these so called sustainable sites. Many buildings start failing and efficiency is reduced to just a number. This is especially true of large structures with complex systems, multiple tenants, and mixed uses. Normally each of these buildings is fully commissioned and operating problems start to surface much later. LEED aims to correct this situation by requiring projects to be reevaluated after every five years to maintain their rating.

In cities like Mumbai, the zoning laws are based so much on the street grid that they are totally contrary to green design. They almost predetermine form and orientation. But there are exceptions that point up the growing influence of LEED and local sustainability mandates, despite the inevitable limitations and flaws of such criteria e.g. Nirlon Towers in Goregaon.

Peer pressure helps too. It would have been nice to have been the first to build this way in History, but that’s okay we’ll just set higher goals the next time.

“Don't tell me the moon is shining; show me the glint of light on broken glass.”

Although even architects agree they lost ground to designs bound by higher energy prices, India has continuously been taking cues from multiple high-rises in Europe, Shanghai, Mumbai, Hong Kong and other parts of the world. Future projects will see even more meddling of architecture and engineering to meet sustainability goals through formal means, and the most innovative examples might occur.

THE WAY FORWARD

The most recent analysis, which was carried, looked at heat gain in traditional homes. The study found that, in a traditional detached house, half of all heat gain was through the roof and through air infiltration/ventilation (28 and 22 per cent respec-tively). The windows accounted for just 15 per cent of the heat gain, rising to 19 per cent in a flatted apartment. This clearly shows that the focus for remedial measures should always be on insulating the roof and controlling infiltration, and the key areas of concern are none other than windows that have to be addressed not just for infiltration losses but also to improve the thermal performance.

Another study commissioned looked at the improvements that could be made to a typical sash window to reduce its heat gain or loss. The tests included the original single-glazed window which had been draught proofed using the Ventrolla system and augmented by the following:-

Traditional timber shutters.

Modified timber shutters with a thin layer of insulation in the panels.

Secondary glazing using a proprietary Aluminum system fitted tight to the existing sash.

Heavy curtains.

A traditional blind.

A blind with a low emissivity (low-E) plastic film applied to the side facing the window.

A honeycomb blind, which has two layers that enclose air, pockets.

After the tests were completed, the window was re-glazed using slim-profile low-E, argon-filled double-glazed units and tested again. (Slim-profile sealed units were chosen because they can be fitted within the glazing bars without obscuring the sight lines.) The results are mentioned in the below table. (table 1)

The findings showed that the chosen secondary glazing system actually outperformed the chosen double-glazing system, with a U-value that was more than adequate for current building regulations.

Several combinations were also tested. Of these, the use of secondary glazing with heavy curtains is

Reduction in heat loss – U-Value in W/m²K

Against reference value of 5.4 W/m2K for a single glass (center of pane)

Description Reduction of energy loss in % Resulting U-Value

Heavy Curtains 14% 3.2

Modern Roller Blind 22% 3.0

Victorian Blind 28% 3.2

Honeycomb Blind 36% 2.4

Modern roller blind with Low-E film 45% 2.2

Shutters 51% 2.2

DGU in Slim Profile 55% 1.9

Modified Shutters 60% 1.6

Secondary Glazing System 63% 1.7

Table 1

| 12 WFM NOV-DEC 2013 |

the most likely to be encountered in homes at night, achieving a U-value of just 1.3 W/m²K, and a heat loss reduction of 66 per cent against single glazing.

The findings do not mean that secondary glazing is always more effective than double-glazing, as many factors affect its performance. For example, the spacer bar around the perimeter of the pane of a double-glazed unit will conduct more heat than the centre of the unit, so a double-glazed small-paned window such as a 6ft x 6ft sash window will be less efficient than the one with a single pane. Nevertheless, the analysis does show that, from a heat performance perspective, the use of properly installed secondary glazing provides perfectly adequate levels of insulation, which can often be more effective than double-glazing.

HISTORIC AND AESTHETIC SIGNIFICANCE OF WINDOWS

Windows are the key to the character of historic buildings or buildings built with no greening principles. A minor change like increasing the thickness of glazing bars can have a dramatic impact on the character of a window. Reflections are also extremely important, in a small-paned window, each pane reflects at a slightly different angle, resulting in broken reflection lines across the window. This variation is lost when dummy glazing bars are planted onto the face of a large sheet of glass. Old

glass itself has a unique character; crown glass has radiating ripples and is widely found in small-paned Georgian windows, while the cylinder glass commonly found in windows made after 1845 has parallel ripples. Both distort reflections across the pane, adding character to the appearance of the building.

As so often in conservation, a solution for one problem raises further issues. Designing a successful programme of thermal improvements requires a holistic approach to the interior environment of the building by a specialist who understands how historic or in use buildings work. There is no single answer. Each situation needs to be considered individually.

STRUCTURAL GLAZING – An ode to modern façade design

Structural Glazing systems are a brilliant, cost effective solution for contemporary glass design. Structural Glazing systems consist of a fully or partially framed internal finish, with the glass structurally adhered to the outside face. All to produce a complete flush silicone jointed external finish. Whilst the framed internal appearance is more traditional, structural glazing provides a high flexibility in regards to the sections utilized and framework finish.

“People are constantly asking Portia and me if we are going to have children. We thought about it. We love to be around children after they've been fed and bathed. But we ultimately decided that we don't want children of our own. There is far too much glass in our house”

- Ellen DeGeneres

| NOV-DEC 2013 WFM 13 |

From a weathering perspective, Structural Glazing systems are typically reliant on the application of sealant. Therefore once a Structural Glazing system has been installed and initially tested under severe weather conditions, weather integrity should be maintained for at least 20 years from application.

As structural glazing systems do not rely on internal weep systems and subsequent drainage, they may be installed at as low as 3-5 degrees pitch. System comprises of structural glazing tapes, a polyurethane structural adhesive (air cured) and the internal face of the glass black primed locally over all supporting framework. The glass will be provided with a black spacer and silicone seal as standard, providing a complete black reflective appearance, which conceals the internal frame. Technically the glass does not need to be 4 edge supported, making it feasible

for many applications to contain unsupported glass-to-glass silicone joints.

It is important whilst installing structural glazing that the conditions and environment are correct for the product utilized. Some adhesive methods involve UV light curing through the glass, which in turn may become less effective over spacer bar details. All vertical structural glazing at height should also be mechanically retained.

Structural Glazing is an excellent way of producing a structure, which aesthetically suits most external elevations, and surrounding environments.

Everything needs maintenance. And philosophy aside, Façades, like cars are not maintenance free. They require regular checks and maintenance activities for the upkeep of appearance and ad hoc replacements are to be done when needed which enhances the life of the façade.

The concept of building maintenance is slightly misunderstood in the industry. More often than not it is just considered as a system to clean the façade. However, that’s just one of the various other important aspects of a Building Maintenance Unit (BMU). (Also called Façade Access System or Façade Cleaning System).

All façade components are susceptible to weathering and as time goes by – temperature, UV, dust, rains etc. they all affect them. Dust and grime sets on the glass and ACP panels, rain water mixed with atmospheric pollutants runs havoc on the façade surface. Silicon, the most widely used chemical in the façade industry

also deteriorates with time. We have even noticed birds and bats picking on it thereby making it prone to erosion and deterioration.

Thus it’s imperative that due measures are taken for periodic cleaning maintenance of the building façades.

There are three important aspects of a Building Maintenance Unit –

Periodic cleaning (cleaning cycle)

Identification of the problem area which needs attention immediately or in near future

Maintenance, Replacement or repair job

In NCR – Gurgaon/Noida – which is the hub of new developments and ongoing construction activities, there is a lot of dust suspended in the air which settles on the building envelops hampering their appearance. Therefore cleaning activities should happen at least once in every quarter as per building

cleaning cycle which is ideal.

A neat and clean building enhances the developer’s image. Dirt and grime etc. are chemical in nature – it could be acidic and when mixed with the rain, it destroys the surface of glass and ACP. Thus, façade cleaning is not a onetime process. If building owners think that they can get it cleaned just once a year – it won’t work. Every time a delay is there from the scheduled cleaning, the chemicals take a toll on the components of façade – glass panels, ACP etc. and calls for huge economic repercussions.

Regular periodic cleaning activities on a façade have other advantages as well besides the basic purpose of getting rid of dirt. It helps in identifying the problem area in a façade. There may be gaps in silicon, or a panel which has become loose, or there is some sort of leakage in the panels. All these things can be identified and taken note of and subsequently can be rectified.

Building Maintenance Units– A Necessity For Upcoming Infrastructure

| 16 WFM NOV-DEC 2013 |

POPULAR BMU SYSTEMS

“Access systems are tailor made depending on height and geometry of the buildings (0-50 m, 50-100m, 100-200m and above). High rises and more complex building shapes pose special challenges in designing a suitable façade access system” says Mahesh Arumugam, Director, Meinhardt Façade Technology

In today’s day and age, façade access systems have become technologically superior. A couple of decades back only available systems in India were the portable ones which needed to be moved manually, but now there are motorized systems available with varying degrees of automation possible.

Some of the popular façade access systems are listed below:

1. ABSEILING – rope access or spider man as it is popularly called is one of the popular systems mainly deployed for cleaning (Fig1). The system includes mountaineering equipment and

rope with inbuilt safety mechanism of secondary rope. The rope needs to be installed with safety anchor at the top of the building. Additionally, these ropes and equipment need to be regularly checked and logged. Spiderman is mostly used in small projects that need economical maintenance solutions. It is also used in buildings and specific areas where access through any other system is not possible. E.g. in atriums or U shaped alleys where it’s impossible to incorporate more sophisticated systems

Limitations of Abseiling

This technology is meant only for cleaning of the facade. For other maintenances like glass checking, glass replacement and mastic filling, alternate façade access systems are needed.

This could only be used for short durations as it may hamper the blood circulation of the worker. However, with advancement of technology,

Special harnesses are now available to allow a full 8 hour working day without blood circulation issues. To improve the cleaning cycle, more workers can be deployed simultaneously to make this the fastest cleaning system.

Another peculiar limitation that we have come across is that a single man hanging down the ropes scares off the occupants of the building

There is also one advanced form of abseiling which is used and is popularly called – The flying chair. In this the person is sitting comfortably on the chair which is completely automated with hoisters, motors etc. and all the equipment is hanging on the chair instead of in the hands of the man power deployed. Its more secure and anchor equipment on top of building are more permanent.

“People are like stained glass windows – they sparkle and shine when the sun is out, but when darkness sets in their true beauty is revealed only if there is light within”

- Elizabeth Kubler Ross

2. GONDOLAS or CRADLE SYSTEMS – mother of all the cleaning equipment is a cradle with double suspension system hanged from brackets, davits attached on the top of the buildings. It is suspended on 2 sides by 4 very high capacity steel wire ropes. One on each side has a motor attached to it and other two are the safety ropes. It works on the same principle as that of an elevator similar to construction gondolas.

A gondola is big enough to carry two people and the equipment required. A standard gondola/cradle that is used internationally is either 2, 2.5 or 3 meters x 0.8 meters with a weight restriction of 240 Kg according to the CE norm.

“In India there is no standard law which specifies this industry. However we have taken some cues from BIS standards. We have designed gondolas up to 2.5 meters in length, so that we can take up panels of up to 2 meters width as per project geometry requirements” Sunil Malhotra, Director, Apple Tree

The safety is taken care of by its inherent design. A gondola is suspended by means of 4 highly tensile steel wire ropes. They are either self-climbing cradles or with roof mounted BMU trolleys. If either wire breaks, then a safety lever (which is there in a standard gondola) can be pressed and the gondola/cradle is safely brought down and parked. Besides, like everything else, gondolas/cradles too have to be maintained and certified to ensure safety as per

codes, guidelines and good industry practice.

3. MONORAIL System – this is most commonly used from the point of practicality in our country. This portrays all the aspects of a fully automated BMU and yet is inexpensive. There is a rail that runs on the outer periphery of the building roof and the cradles are suspended from them and can cover the complete perimeter of the building.

Limitations:

Since it is visible it hampers the aesthetics of the building so it’s not liked by the architects. However, with proper planning and design integration means can be devised where the whole system can be camouflaged and become part of the system design.

4. BMU on track

The safest system that has become synonymous to BMU is the one where there is a roof mounted BMU machine moving on the rooftop on rail tracks or on its own motorized guided wheels. Ideally it is designed at the time of building design and conception and arrangements are made in the beginning only to incorporate this. Man power required is least. 2 people can actually clean the entire building. Maintenance is less and it’s fully automated. It can be tailor made according to the individual building requirement.

The length of the boom can go up to 45 meters. And all around 360 degree movements are possible

through hydraulics and mechanics, luffing, soft rope restraint system for all round cleaning of the building. If designed and maintained properly the life can exceed 30 years. This is the concept widely prevalent in west and middle-east.

INTEGRATING BMU DESIGN WITH THE BUILDING DESIGN

BMU’s are an essential constituent of every building but are ignored largely. The way forward would be to integrate them at the early stages by appointing consultants, and incorporating within the system design and conceptualization from base level with the architectural

blueprint of the building. It is an essential part of the planning and design and must be incorporated right at the beginning.

Typical information required for planning a BMU:

Perspectives / 3D sketches / Model pictures

Roof plan both architectural and structural

Elevations

Floor plans – ground, each typical floor type

Roof equipment layout: Clear spaces on roof

Exterior wall sections of the façade showing recesses or projections

If the above factors are taken into consideration right at the beginning then maintenance in future is a cake walk as a

well-planned and efficient BMU can be devised only if it is integrated right at the design stage.

FUTURE OF BMU

Every building needs maintenance and in India more and more buildings are coming up. At the end of the day it’s a challenge to clean and maintain them. BMU have to be deployed.

Next generation of façade

cleaning systems are bound to change the face of this country. Many of them are already foraying into Indian Market. An example for next generation access system is where the suspension of the cradles is the same i.e. either on roof top tracks or external monorails, but the cradles are automated with inbuilt washers. It sprays the cleaning agent onto the façade surface and cleaning can be done automatically. However

for repair or maintenance jobs, manpower will have to be deployed and another limitation is that if a building has a fancy façade with fins or protrusions, then it can’t be used.

Another next generation system which is already being used is where the cleaning system is incorporated in the façade itself. Each window is equipped with its own motor and wiper. The motor sprays the cleaning agent and wiper brings it down while cleaning the window. But it is very expensive to have individual system for each window. Then wipers have to be maintained and replaced from time to time.

An extraordinary advancement in the technology has come with the Robotic Cleaning – it’s a square box which is stuck on the window. It measures the area of the window to be cleaned with help of laser. It is filled with the cleaning liquid. It moves on the façade area in a predetermined movement calculated with help of its CNC system and then automatically stops and parks itself on one corner one’s finished cleaning. Then you need to put it to the next window. It’s great innovation for smaller areas vis-à-vis residences or shop-fronts.

Thus we see that the technology has come a long way and is continuously evolving. The BMU are something that are an absolute necessity for any building.

HEALTHY BUILDINGS – ROLE OF EFFECTIVE FENESTRATION

Source: Trosifol

On average, we spend about 90 percent of our time indoors, thus it’s imperative that we have an indoor environment which is conducive to general wellbeing of the occupants. There are a number of factors that influence the indoor environment in any given building. Be it an office space or a house. For instance – Indoor air quality, natural lighting of the indoor spaces, clean ventilated and well lit interiors, bereft of annoying outdoor noises. Windows and façade play an enormous role in ensuring the building’s indoor environment is healthy. They are responsible for ensuring that the interior spaces are well lit and adequately ventilated. And while ensuring this prime objective they take up the dual responsibility of acting as a barrier between inside and outside and keep the unsolicited intruders as Noise, air pollution, rain, humidity at bay. It is of utmost importance that a building façade is designed with a holistic approach keeping the wellbeing of occupants in mind.

How detrimental an unhealthy building can be in case its windows or façade are not sensitive to the health requirements of its occupants? The key facts shall be discussed in 2 consecutive issues of the Window and façade magazine. This issue shall particularly address the noise hazard on human wellbeing.

Noise

It is customary to call any undesirable sound "noise." The disturbing effects of noise depend both on the intensity and the frequency of the tones. For example, higher frequencies are more disturbing

than low ones. Pure tones are more disturbing than a sound made up of many tones.

It is one of the foremost responsibilities of fenestration system of the building to keep this undesirable element out

EFFECTS OF NOISE ON HUMAN HEALTH: (Fig 1)

Unrestricted noise can cause

loss of concentration,

hypertension and vasoconstriction,

Mood swings/ annoyance/ and sleep disturbance,

Palpitations

Permanent hearing loss or hearing disorders of irreversible nature.

Changes in the immune system and birth defects have been attributed to noise exposure.

Sound is well transmitted into the uterine environment thus causing immense and irreparable damage to the fetus (Fig 2). The U.S. Environmental Protection Agency authored a pamphlet in 1978 that suggested a correlation between low-birth weight babies (using the World Health Organization definition of less than 2,500 g) and high sound levels, and also correlations in abnormally high rates of birth defects, where expectant mothers are exposed to elevated sound levels, such as typical airport environs. Specific birth abnormalities included harelip, cleft palate, and defects in the spine.

When young children are exposed to speech interference levels of noise on a regular basis (the volume of which varies depending on distance and loudness of the speaker), they may develop speech or reading difficulties, because auditory processing functions are compromised. Children continue to develop their speech perception abilities until they reach their teenage years. Evidence has shown that when children learn in noisier classrooms, they have

a more difficult time understanding speech than those who learn in quieter settings.

In a study conducted by Cornell University in 1993, children exposed to outside noise in learning environments experienced trouble with word discrimination as well as various cognitive developmental delays. In particular, the writing learning impairment known as dysgraphia is commonly associated with environmental stressors in the classroom.

The effect of high noise levels on small children has been known to cause physical health damages as well. Children from noisy residences often possess a heart rate that is significantly higher (by 2 beats/min on average) than in children from quieter residences.

It is the duty of the window / façade contractor and responsibility of the architect to consider the acoustic performance for the building, particularly in

circumstances where external noises may be significant or may be a nuisance

To scale down an existing noise nuisance perceived as loud, 2 fundamental physical effects of wave propagation may be exploited:

Sound isolation by REFLECTION:

The sound energy is not dissipated or converted to a different energy form, but its direction of propagation is changed by reflection.

Sound isolation by ABSORPTION:

In this case the sound energies are essentially converted into heat (dissipation)

Influencing Factors

Glass performance / spandrel panels

Area of the Fenestration product

Frame Performance

Air tightness of

Installation

The opening frame

Building Height

Typical Glass Values

Double glazing was originally developed to reduce heat loss through windows. However, by judicious design, it is possible to achieve moderately high acoustic insulation. A double glazed

window with 4/12/4 will typically achieve the minimum 29dB for residential doors.

Noise control should be taken into account from the beginning of the planning process for a new building:

The frame, glass, and special installation techniques should be selected so that all sources of disturbance can be provided with effective vibration isolation.

While this issue deals with the noise as a health deterrent and how effective fenestration can help in combating that, the next issue will talk about the sick building syndrome and the role of fenestration to avoid that. Until then….

SELECTING FENESTRATIONSOLUTIONS

About Author:

The author is an architect and has over 18 years of professional experience and 13 years with Edifice alone. He has participation in over 50 projects from various sectors and is currently the Regional Head and Director at Edifice and head of operations for the Pune and South Maharashtra region. He has been formally trained at the University of Pune and the South Bank University in London, respectively and has travelled to over 15 countries understand architectural trends, spaces and their effect on human senses.

Designs should be sensitive to context, client, environment and business processes and the same principle goes in designing a beautiful yet functional façade. In fact, the first gesture of an architect is to draw a perimeter; this perimeter which separates the microclimate from the macro space outside, yet is an ode to the communication between finite and infinite.

Conveying this idea, there are various factors which

are considered important while designing, specifying and selecting a window or a façade solution. Presented hereafter is some of our best architectural work that represents factors that architects need to consider while selecting window/ façade systems.

Framing views:

Referring to the strategic positioning of the windows in order to visually connect the inside with the outside, this is an important consideration creating an inside-outside experience. For instance we removed an industrial bay and a gable wall of an industrial building and replaced it with glass (fig. 1), this brought in the light to the office interiors and also created a “respite space” between two gable elevations thus adding a lot of value. Evidence mapping indicated that the spatial effect contributed to 15% increase in the efficiency of the occupants over 6 months after occupying the space.

Thus, strategically positioned windows in a building façade enhanced the aesthetic and functional value of the building in a big way.

“At the core of every design is functionality supported by objectives, requirements and possibilities.

While some spaces are content being functional, others evolve into aspirational art forms. The difference is not in technology – the difference is DESIGN…”Ar. Rahul Ajeet Kadam

Regional Head & DirectorEdifice

Responding to the Climate:

Contextual climatic considerations are very important for positioning of windows as optimal heat gain, sound privacy, zero water egress, etc., all need to be planned for while selecting a suitable window or façade solution. Local sun path, incidental solar angle during various times of the day and during different seasons, relative humidity prevailing all through the year and at particular times, rainfall etc. play a crucial role when an architect is conceptualizing the façade design.

For instance, in this project sun path diagram was analyzed and the façade was given an 5 degrees slant (fig.2) which cut the incidental solar radiation of the north – west, evening sun between 3 to 6:30 PM, which comes at an 18 degree angle in Hyderabad. The small atrium on the south side protects the floor plate from heat gain and the east and west side is protected from heat gain by positioning of buffer spaces stores, toilets and stair cases.

Articulating Fenestration: Respecting the architectural language and theme

The window solutions need to keep up with the architectural vocabulary and theme of the project, as windows are an important fenestration module. The building façade has to gel with the theme of the building design, giving the building an architectural character through its architectural vocabulary depending on the form of the building, the

fenestration can be articulated to linear or horizontal or natural forms emulating natural elements (fig 3&4), by deploying sophisticated digital architectural techniques, as presented in this case wherein the façade is also the structural skin of the building thereby giving clear spans in the interior space to make it extremely flexible and free of structural columns.

Accentuating Scale and creating openness

The window as a module plays an integral role in creating the visual impressions. They can accentuate the scale horizontally and vertically. Smaller spaces if adorned with long double heighted windows can give a feeling of scale to the same space (fig.5). On the other hand strip windows can be used to accentuate the length of built form (fig. 6).

Modular Planning :

A modular planning can also develop an interesting façade design, vis-à-vis using a stone panel grid to create a façade elevation with discreetly positioned windows. Cladding with various alternate materials can be used to create a visual and functional treat (fig.7).

Planning for Disaster :

Safety considerations are of utmost importance and can’t be overlooked for other details. Disaster situations like fire, earthquake, terrorist attack, suicide, etc need be planned for and behavioral patterns need to be understood. Particularly for public buildings hospitals, hotel auditoriums, convention centers, commercial spaces etc.

Windows have to be designed for fire safety and seismic tolerances. Testing should be done before approval ensuring the window or façade component shall withstand all the natural or manmade disasters.

Apart from above, basic safety concerns like raising the sill height to prevent accidental falls and ensuring the right opening and closing when required, having restrictors to prevent banging and breaking of glass are some of the other lesser but significant factors to be considered when conceptualizing the window elements for a building or a facade system.

Responding to Human senses :

The window has a direct relationship with the sense of Sight and smell. Many sensitively designed projects have demonstrated that if windows are well planned and positioned they can positively respond to human sensibilities. For instance framing views articulately in hospital windows can add a lot of warmth and character to the space (Fig. 8). This in many ways reduces the psychological feeling that one is sick and helps respond to the circadian rhythm in tropical countries, as people in the tropics are physiologically designed to see/ live with sun light.

Maintenance:

A complete topic in itself, suitable maintenance considerations need to be undertaken while selecting and designing a window solution for a given project. As this has a direct relationship with the cost of ownership.

While there are endless means by which an architect articulates the building fenestration, above are the

few which holds the fancy of most of us and makes the list of key factors influencing the fenestration design and selection of solution henceforth. We believe if planned right, understanding the specific needs of a particular project, any façade or fenestration can be executed right.

In conclusion I would urge and request to the fraternity to think sensitively and practically while selecting, integrating and installing façade and window solutions to create a better future….

Rise & Rise of Glass Wall Systems

As the face of Indian skyline changed in the past decade, one name that shines bright and stands apart, as the name itself suggests is the Glass Wall Systems. WFM got an opportunity to have an interesting chat with Kamlesh Choudhari & Jawahar Hemrajani – Directors of Glass Wall Systems who gave a candid insight to the rise and rise of the phenomenon called Glass Wall Systems

Please shed some light on the emergence of Glass Wall Systems?

Glass Wall started in the year 2000. That time, the industry was still in its infancy and there was no encouragement for usage of aluminium products. wood was the most preferred fenestration material at that time. In those days, aluminium was not seen as a viable substitute, it was looked down on as not very strong and sturdy material. It was considered as a thin material which would not have the required strength. Slowly the industry grew, there was a big debate on advantages of aluminium and its usage, the developers started to accept aluminium, knowing the advantages aluminium doors and windows provide. And then there was one project after another and no looking back! (Smiles)

What would you deem as a turning point in the making of Glass Wall Systems as the prime league Façade contracting company?

The turning point in the whole situation came in 2002, when we executed Reliance Petroleum Headquarters in Navi-Mumbai. In those early days, imported glass, fully unitized systems, stone cladding, sun shades, frameless glazing, you name it and all was incorporated in that one project which was valued at INR 350 million in year 2002 – that was a big turning point not only for us, but for whole of the industry

when new technology came in place. In those days, people used to work on site, cutting, drilling, fabrication everything was done at site. On the other hand, in this project, it was more factory-oriented, fully unitized panels were pre-fabricated and brought to site for installation. In this project, we could prove ourselves as a self-sustained, fully equipped façade engineering company as against a mere façade contracting firm. Then slowly we kept on growing ourselves – with more and more new innovative ideas, products – stone, glass, performing glass, unitized systems etc.

What specific measures you took to prove your mettle?

Our reputation was that we the promoters of this company came from an industrial background and not from a contracting background. We took this as an industry and not mere contracting. Here everything is engineered, made in factory and brought to site. The process is controlled. There’s no need to use any scaffolding outside the building which takes up a lot of ground area as with unitized system, installation is done from inside the building, and thus quality & safety is a much considered aspect at Glass Wall Systems.

We focused on retaining the repetitive customers. The market was growing and our customers grew too. The builders who were building 7 to 10 storey started building 20 storey buildings which boosted the high rise culture of Mumbai. The actual number of buildings remained same, but the volume grew enormously and Mumbai’s geography helped a lot. Since it’s surrounded by water on all the three sides, there is not much scope but to grow vertically. Challenges kept on coming and we kept on performing. Our engineering was impeccable. Delivery became our USP –“ok give it to Glasswall, the project will complete on time” this was often heard off!

Project Antilia – How challenging was it for Glass Wall Systems?

This project was a tremendous engineering challenge (it is built to withstand an earthquake of magnitude 8 on Richter scale with extra-high ceilings). We as Glass Wall could generate enough confidence in the client and the project was awarded to us. The successful completion of Antilia was a great milestone and changed the whole scenario and put Glass Wall Systems on a different pedestal altogether.

On one hand, we were doing

engineering challenges and on other we were doing volumes with Rahejas, Indiabulls, HCC in various cities like Bangalore, Ahmedabad, and Kolkata. Everything fell in place brick-by-brick, step-by-step, from there to here and from here to here (pointing at the picture of Vasukamal building).

Considering the current challenges faced by the industry at large, how do you gear yourself and your company to withstand them and to keep on doing the best of the Projects in India?

Challenges! (Sighs) there are big challenges, firstly because of geographical location, secondly, in the current development stage we are looking at the developed world and we want everything to come from there as fast as possible and as similar to what has been executed there. Engineering being the strong base of our company, we don’t find this as a complexity, we don’t think it’s too difficult if we have the concept right for the kind of façade executions that we are doing in our league. Every building is different with different structural and performance requirements. Wind loads in Delhi are not same to those in Mumbai. So if we have the correct engineering and proper planning, everything falls in place.

Talking about immolating west, are we simply borrowing technology and products from there or doing some value engineering specific to our local requirements?

Good thing about our industry and India in general is that we are flexible. We consider Indian engineering to be the best. In

terms of specific requirements of client, we as a company try to give them value for money as per the specific need and not just copy some A, B, C European Company and bring it over here, it’s not like that. This is what differentiates us from others that we are not giving off the shelf solutions like most system companies and other companies do. We do customization for each project. The architect’s or client’s requirement is of prime importance and so is the market and budgetary consideration for each project.

Do you ever outsource some job to some third party agency?

We can’t do that. Control is out. See, we are going taller and taller every day. Earlier we were doing 180 meters now I am doing 416 meters. So from 180 to 416, if we don’t have people who know there job well, we can’t do a successful job. So, personnel skill is very important. And with

outsourcing I can’t be sure of that. So No. we don’t outsource any job.

As we go up, how important is the functionality in window or façade? How do you make sure the openable component is up to the mark?

Functionality is very important and hardware plays a very critical role in this. To give you an example, we are doing this world tower in Mumbai which as of now, till date is the tallest residential building in the whole world at 416 meters. When this building was awarded, the key challenge was a wind load of 4.75 kPa. When such a wind blows a person is parallel to the ground, you can’t stand on your feet. And at 4.75 kPa, you’ve got a sliding window. Nowhere in the world there is a window which has been tested for this kind of wind load. So when we went on board as the chosen company on this project, we did a lot of engineering, from procurement of the hardware – pre qualification of

the hardware companies from around the world was done, the best of hardware - rollers etc. were identified, aluminium structure was designed keeping in mind the static and dynamic loads. The heavy aluminium, glass – bi-laminated DGU and shutter size 2.7 meter x 1.3 meter resulted in the shutters weighing almost 250 – 300 kilos. And that has to be moved, in those wind loads it has to be moved, it was a big challenge. And we are very glad to say that our team could achieve that engineering, we tested those windows in an international laboratory in Dubai and for the 1st time in the world, the façade windows were tested for this kind of wind-load for this kind of performance. Air infiltration, water infiltration, hardware performance and everything was tested and achieved. So, what we feel is that if you have engineering right and the proper product, then everything falls right.

So the key is precision engineering?

And the correct product. We got wonderful support from our suppliers. So, with the right hardware, right technology and right product – everything falls in place and that too at an Indian price. The client is not paying in dollars. All we want to say is no feat is unachievable. You just have to identify the right place, right product, and right ways and everything can be done.

How do you perceive sustainability with respect to our Industry?

In this internet world, everything is available online. The real challenge is how you translate that technology as per your client’s requirement and satisfy them.

Sustainability to us means production, engineering, factory should be well equipped with all the latest CNC machines so that there is less dependence and minimum errors, latest technology in production, faster curing of glazing panels, better logistics on the building to move the glazing panels on the project. All in all we need to continually improve and invest back into the industry, be it on resources, factory or logistics and that has been Glasswall’s mantra. We have been pumping in these investments back – from one factory to the next and then to the next. According to us having the best of Human resources – man power – that is our biggest strength, good factory and in-house processes vis-à-vis coating, fabrication etc. make us a sustainable organization. Having everything in-house makes us more flexible, we are able to shift priorities. The project viability is more. So the lesser dependence, the more sustainable one can be in this market.

Glass Wall Systems is known to

have achieved an accelerated growth during the past decade. Where do you see yourself 5 years down the line?

We started with a family of around 10-12 people. Today we are a strong family of more than 400 people – technical and administrative staff and more than 2000 worker staff. From there to here we see ourselves growing. We currently hold the leading market-share in the industry.

We received consequently Façade & Fenestration Contractor of the year 2012 & 2013 by Construction Week.

5 years down the lane, it’s one of our wish to see ourselves as the 1st listed façade company of the country with a turnover of 1000 Cr as soon as possible.

Energy Efficient Window System- Reality Check Under Indian Conditions

The construction of buildings has evolved to newer heights in past few years, so has the awareness on conserving energy. With the Kyoto protocol signed so many years ago and increasing global awareness about climate change, even a school student is now aware of energy conservation.

In any given building, its envelope is the main point of heat exchange. As much as 41% of energy might be lost from the fenestration depending on the window to wall ratio.

If we look at a picture of a house from a thermal camera (fig 1), you will notice that the brightest red lines, or where the heat is transferred most from, are the frames of the windows, yes, even more than the glass. Energy finds the weakest point between the walls, frames, and glass to pass from. It is apparent in the above thermal analysis, where the isothermal lines are very constant at the glass level, but there is more activity at the level of the frame where the

energy flow is higher.

Until a few years ago not much importance was given to Fenestration and was mostly hidden behind the curtains. Today the fenestration area has come out of the curtain and is liked to be shown off. Aluminium is vastly chosen amongst available options and due to its strength, structural stability it provides and its ability to be coated in any colour or finish desired it surely is the most durable and aesthetic product. With the aluminum window systems companies operating in the Indian Market, there are plenty of solutions today for highrises, double height windows, minimal sight line windows, etc. and of course, you cannot have glass façade without aluminium framing behind it.

But can aluminium windows be energy efficient? Can they improve acoustics? The Answer is yes. Alumimium windows with thermal break are highly energy efficient. If used with the proper combination of glass, they dampen the noise effect also.

A pertinent question is asked many times, does India with its tropical climate need thermally broken windows? On looking at the climatic data, one would say it does not. But a closer look at the reality may force us to change our minds. India is 6th largest energy consumer in the whole world. Today, in almost all the semi luxury apartments in the major Indian cities, and in all of the commercial buildings we find extensive use of air conditioners which constitutes a major portion of the total electricity consumed. The difference between inside and outside temperatures have risen and with it the need to create a thermal barrier between inside and outside to prevent the energy loss.

Fig. 1 - IR Image showing loss of heat from the framing area

| 34 WFM NOV-DEC 2013 |

Let’s look at the thermographic image below (Fig. 2)

When we compare the 2 windows, non-thermal and thermally broken (with one window open to show the source of heat), using a thermal camera, we can see that with an external heat source of about 61 deg. And an inside temperature of about 19 deg., the surface temperature of the frame in a non-thermal window is about 30 deg. And in the case of a thermally broken frame, we have about 26 deg. For those of you who are Mechanical Engineers, I think you will appreciate the air conditioning power it takes to cool a room with 4 deg.

Use of double glazing is now a necessity. In a scenario where double glazing is used in a non-thermally broken aluminium frame, there is always a possibility of energy loss in tune of 80%. So the energy saved by the double glazing is lost through the non-thermal frame. In ideal conditions, it is found that you save around 30-40% of energy by using thermally broken aluminium frames with double glazing units.

Here is a comparison of 2 almost identical systems (Fig.3), one without thermal break and one with thermal break. You can see the difference in the internal temperature and the heat flow inside the frame. A typical non-thermally broken window will have a U(f)-value of over 6 W/m2K, while that of its thermally broken counterpart will come out to be around half.

We also see the thermal lines where the glass is almost constant and the thermal action is mostly in the frame (Figure 4). You can see from the small movements in the frame that this is a very well

isolated system. So this is saying that if we have a temperature of zero degrees outside and 20 deg. inside, the surface temperature of the frame is about 17 degrees, which is very good isolation.

Thermal break aluminium profiles use an isolating strip made of Polyamide with 25% glass fibre in 3D structure to provide insulation. It is a thermo-plastic material which is 500 times less conductive than aluminium at the same time is structurally stable due to the glass fibre content. Figure 5 and 6 show the working of a typical thermally broken window and a curtain wall.

The rate of expansion and contraction is similar to that of aluminium. So it acts as an integral unit without any risk of derailing.

It is observed that as you increase the width of the insulation area and as you break them down into smaller chambers, the better insulation you get.

which are far more stringent. In the 12th five year plan (2012-2017) the target of Government of India is to have 75% of its new buildings to be ECBC compliant. In addition 25% of the existing buildings are to be retrofitted to be ECBC compliant.

Currently Aluminum window systems companies like Kawneer, Reynaers, EFP, Ponzio, Profils Systemes,

etc. are established in India and actively promoting thermally broken aluminum window systems. Indian Fabricators, such as AGV Alfab, Alamdar Fabricators, Thermaline, Durall, etc. have designed indigenous thermally broken window systems.

Technoform Bautec, being the global leader in manufacturing of polyamide strips for thermal break aluminium profiles, is always at the disposal of system companies, façade & window manufacturers, developers, architects and government agencies to recommend and advise ways and means to conserve energythrough thermally broken aluminium fenestration systems.

There are many examples in the country using this system successfully like in the Hospitality Industry. Some examples are:

ITC Grand Chola (Chennai)

ITC Park Sheraton (Chennai)

Other most recent examples are All India Institute of Medical Sciences in Bhubaneshwar and 4 other cities currently under construction.

Even residential projects are not behind: DLF Magnolias in Gurgaon (Fig.9) was the one of the first residential projects to use a thermally broken aluminum window system. Many more residential projects like Pooja Constructions in Mumbai (a 17 storeyed building) is currently under execution. Therefore there is certainly a growth in awareness and need for these systems in India.

The Government of India through its Bureau of Energy Efficiency has launched a programme for Energy Conservation Building Code (ECBC), which involves the construction sector. The ECBC code was launched in 2006 with the implementation date of January 2014. As of now, it is already mandatory for the Central Government Projects to be ECBC compliant and various state governments are in the process of launching their own state ECBC codes

Face to Face withAjay Tenany

India has always embraced new technological advancements with open arms. With the advent of spurt in the growth of Indian construction industry in 2006-2007 many multinational companies forayed into India. One such Solution provider is Reynaers Aluminium. Headquartered in Duffel, Belgium, Reynaers Aluminium is represented in over 40 countries worldwide and is market leader for developing and selling innovative and sustainable aluminium systems for building sector. Reynaers Aluminium ensures its financial success by integrating social and environmental considerations into all its activities.

WFM got a chance to interact with Ajay Tenany, who is the Director of Reynaers India and is responsible for sales, marketing and operations of the Indian subsidiary. He has a vast experience in building industry. He marketed interior application products like window coverings; blinds etc. and he had a brush with façade contracting business when he joined Alupro. He was the country sales manager for Assa Abloy before he took the reins of Reynaers operations in India.

How do you perceive Indian market as of now when it comes to windows and façade?

As per the construction statistics – the opportunity seems to be very high. We are just touching the surface and there is a huge gap between the products being offered and what can be offered. The fenestration technology has come a long way, but what is being applied in majority of the projects is very basic. So the opportunity is there for us as system suppliers. For any company this opportunity lies in bridging the gap. If we can bridge this gap, we can churn numbers.

As far as the economic cycle is concerned, there will be ups and downs. But opportunity will remain. None of us has touched the critical mass yet. So, for coming few years we have nothing to complain. The construction industry might grow at 12%. But you have a potential to grow at 25%

How has Reynaers evolved in past 6 years of Indian existence?

Any company that comes from abroad has a wait and watch policy for the initial years, they will first test the waters. We too

entered as a liaison office with all the challenges and limitations of being one. We were just a communicating channel for the Belgian office and Indian customers. Then we became private limited, so there was an obvious shift. Now we are thinking of local sourcing, so that the prices are optimized. These are the step by step developments that we are undertaking to penetrate the market.

What’s your strategy to tap this untapped segment of the market?

We follow a three pronged approach

Firstly, from being a 100% imports driven entity we are now developing a few products suited to Indian environment, for Indian market that shall be locally sourced from here to cut down on the logistics cost and to penetrate the market better.

Secondly, educating the prospect – if we don’t do that, it doesn’t lead anywhere. So, most of our effort goes into explaining the people. Whenever we go and

meet some developer or an architect, the initial resistance is too high, and then eventually they start opening up after a couple of interactions. They listen to what we have to say. The credit goes to my competitors too. Say, for example, if my competitor has gone to meet a client and I approach the same person later, he already has an idea and is more receptive to what I have to say. In a way we are shadow marketing each other.

Thirdly, developing the Indian specific product after due diligence, which will happen in its own wake. Like I said earlier – none of us have achieved the critical mass and we are yet to arrive at a point where we start developing “India specific products”(Fig. 1)

Please elaborate on “India Specific Product”

Window where grill and mesh

both can be incorporated. If you ask me, I can provide mesh. But grill? The point here is that any company that comes to India won’t do that investment in research and development right from day one. This happens when the market is growing for all of us and I think the time is very near that R & D shall start for India-specific products

Which projects you would like to make special mention of that helped Reynaers reach its current position?

There are three projects which are very close to me.

DLF Magnolia – Over 25000 sq. meters of thermally broken lift and slide doors. We did this project with Star Alubuild. Reynaers windows were installed in the front of the houses – all living and bed rooms (Fig. 2)

Wadhwa’s Address project – Ghatkopar Mumbai – Over

50000K sq. meters of Non Thermal break systems were installed vis-à-vis sliding, casement, louvers. We are doing this project with Doors & Doors Systems (India) Pvt. Ltd.

Refurbishment of Leela Palace, Goa. Huge 2 track 4 shutter, thermally broken sliding doors were installed for the cottage styled rooms again with Doors and Doors (Fig. 3)

Apart from these there are many more. We did in Pune the first 100 meters building, God’s Blessings by ABIL (Fig. 4). There too we gave thermally broken solution. The fabricator in this project was Doors & Doors.

What do you consider was the key to your successful pitch for the mass scale projects? How could you break the barrier and tap the developer segment, which is considered to be the price sensitive segment, being a system company?

Esha I believe in one philosophy and I believe in it to the core– if I am not able to create a product differentiation and if I am not able to generate that confidence in the buyer, then why would he pay me more? So all my sales people are also imbibed in this theory that create a differentiation. If a customer asks you what’s the difference between x product and yours and you don’t know, there’s no way you’ll ever close the sale. You can meet him ten times, be very pally with him and all, but in the end you have to generate that confidence that he is paying more because he is getting more. The product comparison has to be there. Post that there will be many prospects who would accept the difference, not

everyone will buy for the budgetary constraints but at least we are able to project what we offer. (Fig. 3 – DLF Magnolias, Gurgaon)

Do you organize some awareness generation activities for your customers or fabricators?

We do industry meet in different cities wherein we invite developers and architects. These programs are very helpful in understanding their need and explaining to them what we have to offer.

We also participate in trade shows like ZAK Glass Technology Expo organized by ZAK Trade fairs & Exhibitions. Here we meet lot of prospects and get an opportunity to showcase our products.

Apart from these, we do regular training programs for our fabricators. And fortunately I have got fabricators who are also pro learning and every once in a while they visit Belgium as and when there are some new product launches or training activities.

How many fabricators you have in India?

In span of 6 years we’ve got over 10 fabricators scattered from north to south. We go slow and steady as we try to build relationships – I believe we have to invest a lot of time and knowledge to develop a fabricator. They have to understand the product. You just can’t assume that you have a product, they have a project and they can fabricate it. They have to feel for the product and understand its intricacies.

You mentioned earlier that you source some profiles locally too. How does that work out? You give the system design and obtain the extrusions?

We just started sourcing locally for few of our products from a well audited aluminium extruder who is able to meet our quality parameter. Other high end systems, profiles we source from Belgium.

Do you have a warehouse?

Yes, we have a warehouse in Pune.

Do you import coated profiles or in mill finish and get them treated here?

I exercise both the options. It is on case to case basis and as per the requirement of the client.

However, my view is my client enters into the relationship with my product when he first visualizes it. When he enters a building, he first sees the finish of the profile, then he touches the handle, then he moves it. So if the visual appearance is not good, then he would feel why I spent so much. If we get certified good quality from here, we would prefer sourcing locally. We understand that local content is important for the long term sustainability.

What’s your take on the latest Trends?

The modern trend is the use of minimalistic system and use of energy efficient systems. Reynaers has product lines that cater to the above.

Where do you see Reynaers India in next 5 years?

I definitely see Reynaers as a well established brand over the coming years. With the brand image comes a lot of responsibility and I am confident that we would be able to fulfill those responsibilities.

Indian Surface Finish Scenario &Understanding the Role of Qualindal

India is approaching a fast lane growth in construction sector in which huge role is played by architectural aluminium. More than 5000 coaters/anodizers cater to the surface finish requirements of the architectural aluminium

To understand the current situation, let’s consider the involved parties:

Architects/Specifiers/Owners Applicators Coating Manufacturers

An architect or building owner expects a building built to specification at an agreed price and delivered at the agreed time i.e. Coatings to look good protect the investment and last as long as possible, while an applicator’s

endeavor is to coat and deliver parts at the agreed price and time, making maximum use of their facilities. The coating manufacturer at the same time strives to supply coatings to the applicator which will be applied to an agreed specification and give desired performance as well as customer satisfaction.

The big question is “DO ALL THE EXPECTATIONS MATCH?”

The current situation in many ways is a compromise. Lack of specifications and standard practices result in a huge gap between productivity and performance.

How does Qualicoat help?

Qualicoat has laid down certain specifications which cover the complete range of pre-requisites for rendering a perfect coating vis-à-vis

WORLD OFFAçADES

14th June Chennai: The 5th Zak World Of Facades completes successfully in Chennai with a turnout of 320 delegates. The key highlight was the launch of the Indian Façade & Fenestration Association (IFFA) and Qualindal.

The building façade plays a vital role in bringing the architect's vision to life. It makes a major contribution to the sustainability of a building, influencing both energy efficiency and the quality of the internal climate. It is also an integral part of

the building’s aesthetic, complementing the structural form and defining its visual impact on the urban environment. In India, we still miss the fundamentals of the façade, which is a complex subject for most of us.

The 5th edition of Zak World of Façades held on the 14th of June at Taj Coromandel in Chennai focused on the performance & functional aspects of a façade. While the previous edition in Mumbai focused on the issues of the industry, this CN Raghavendran, CRN Associates

Preview

Imagine loading a 6m frame profile bar at one end and getting all sides of the frame with all machining, dowel holes, water drainage slots, corner cleat holes neatly machined or loading a 6m shutter bar at one end and collecting 4 / 8 pieces (2 track 2 shutter sliding window) with complete machining of lock slots, interlock notches and other hardware fixtures machined. And on top that, just one man is required to operate the machine.

The machine comes with a 550 mm saw which can tilt, pivot or move like a radial saw and can be mounted with up to 30 processing units around the milling station. The tools are mounted in the angle required and save time for coming into position resulting in quick and accurate machining.

There is no loading / unloading time loss or shifting of profile from one machine to another. The machine can process doors, windows and standard curtain wall profiles much faster of width up to 200 mm and length up to 7500 mm. Entire bar can be optimized so that the wastage is minimum or offcuts of 500 mm and above can be loaded to be processed on the machine.

The SBZ 630 comes in 3 parts:

Loading Station

Upto 7 bars of 7.5m can be mounted on the loading station. A pusher with complete programmable gripper pushes the profile into the machine head.

Machining Station

1 The Machining station is housed in a noise reducing enclosure and has two units.

2 A Milling/Machining Unit with a radial head and capacity to mount upto 30 individual units. As these units are mounted in the angle and direction of machining, positioning time is negligible.

3 Cutting Unit with 550mm 7 axis Saw blade which can tilt -45 to +45, pivot – 45 to +135 deg and move radially too.

After the cutting, the profiles roll out on a conveyor for collection.

ESSENZA CASEMENT SYSTEM FROM GIESSE

The unique casement system from Giesse features the flush surface typical of a swing opening door or a window along with the maximum size of the glazing surface and the minimalistic aesthetics of a completely hidden profile.

The sash has a completely glazed surface based on similar technologies to the structural sashes used on continuous facades. It comprises a 6 mm internal glass pane, 27 mm air chamber, a 5 mm intermediate pane, another 32 mm air chamber and a 6 mm external pane.

6|27|5|32|6

The profiles, all featuring thermal break are with 24 mm bars are Euro groove type and house the Futura 3D invisible concealed fittings with a sash load capacity of up to 140 kg.

The FULL GLAZED effect is also ensured by an important innovation consisting of the SMART CORNER joint patented by Giesse which gives side hung Essenza a central profile of minimum dimension.

AIR-WATER-WIND PERFORMANCE:

Resistance to wind-load – up to class C5 (2000 Pa)

Air tightness – Class 4

Water Tightness – E1200 (1200 Pa)

THERMAL TRANSMITTANCE:

With Essenza it is possible to achieve a thermal insulation of below Uw = 1.4 W/m2K and with special glass and dedicated gases it is possible to achieve even higher performance values.

ACOUSTIC PERFORMANCE:

The sound reduction value depends on the type of glass used and can reach a reduction value of 40 Db.
