EDIT

O NOTE

R’S

Sometimes there is a singular fire, which sends shockwaves around the world.

Often we take it for granted and feel that fire will not take place inside the walls of the place we live or work, but the fact is that it can happen at any place, at any time. A fire can spread very quickly no matter how it takes place, and if not suppressed immediately can cause a lot of damage and even result in death.

Modern buildings are filled with synthetic materials that burn hotter and faster than ever, leaving the occupants with as few as two minutes to safely exit the building in the event of a fire. Today’s building and furniture materials burn way faster than the materials that were made in the past. Real wood has been substituted for more composite materials, changing the chemical properties in them and often making them more combustible and rapid burning. The importance of understanding the behaviour of materials in fire is very certain.

Fires can be prevented with relatively simple precautions. Reducing deaths in fires and the impact of fire damage on buildings requires a comprehensive approach to fire safety. In residential, commercial and industrial establishments, compliance with fire safety codes can save lives and property. Ensure your building is robustly protected from fire. Install fire safety systems which will prevent the fire from taking hold and destroying your valuable possessions.

It is time to rethink on our approach on fire safety and security, and work towards more responsible and efficient and safer façade deigns, and this edition's cover story gives an insight on all these aspects.

Facades offer protection from the weather, but they also are essential for maximizing energy efficiency. Facades, along with windows and doors that are properly specified, installed and maintained to ensure conservation of energy. This edition showcases a few interesting articles on smart tools for energy efficient façade design and on designs and materials, which could provide ample daylighting and shading.

This special themed issue of Magazine on fire safety contributes to our understanding of what has been achieved and what remains to be done in order to provide the fire safety engineering design and improved fire performance of structures. We hope that the contents of this special issue will add to the knowledge base in this area, and we invite authors who have been undertaking research in this area to submit more articles pertaining to this subject so that we can regularly compile features on this very important topic.

I invite you to turn the page and read on.

century ago, in 1918, the first generation of cars looked much like a wooden cart with an engine mounted onto it, steering wheels were just starting to replace the tiller, and 50km/h was considered breakneck speed.

When compared to the latest Tesla or BMW electric sports cars, these early automobiles simply pale.

Similarly, the Curtiss NC-1 biplane of 1918 had a maximum speed of 144km/h and a range of 2,500km, while the modern Lockheed Martin F-22 Raptor features a top speed of 2,500km/h in addition to a host of other high-end capabilities unimaginable back in 1918. Perhaps even more striking is the evolution of Information Technology. Only fifty years ago, a computer that was capable of performing only the most basic of tasks would have filled a very large room. Today, most of us have smart phones in our pocket that can perform the same tasks a billion times faster.

Looking at construction technology one hundred years ago compared to the present day, the differences between concrete- or steel-framed buildings of now and then may not be immediately

obvious to the untrained eyes. On the other hand, façade technology has evolved and improved by leaps and bounds in that same period. There isn’t much in common between the early days of small hand-blown glass panels in steel frames to the modern fully aluminium unitised, pressureequalised and fully drained curtain walls with low-emissivity double-glazed units. It thus seems appropriate to carry out a systematic review of the various new and upcoming techniques in the design of building envelopes.

BIM DOCUMENTATION Just a few short years ago, BIM technology started its unstoppable ascension, even becoming the de facto method required to be used for submissions and applications to local authorities in some countries, including Singapore and the UK. The benefits of BIM are clear: closer coordination between various disciplines, detection and avoidance of clashes, 3-dimensional modelling of buildings, as well as a host of other advantages, depending on the savviness level of the design team. Yet, as is often the case with drastic changes, strong resistance to the progression of BIM could

be felt throughout the façade industry. I should confess that I was one of those that could not see its advantages through the hurdles linked to its implementation.

Now, two years after our team has made the leap into full BIM implementation and documentation of the building envelope, I feel that there is no turning back, and it is all for the better. Clearly, shifting to BIM design of façades requires strong commitment, since the training and mindset needs to evolve. However, once the initial investment is made, it pays off quickly. The whole documentation process is much faster and accurate as compared to traditional CAD drawings. More importantly, because the façade is designed comprehensively in three dimensions, revisions and amendments are very easy to implement, and section, plan, elevation and detail drawings are always consistent. The adoption of BIM effectively eliminates the risk of discrepancies between different sets of drawings and between different disciplines.

disciplines making their way into new developments. Coordination between these various disciplines by traditional means is a major source of problems and inefficiencies in the design process. Integrative design aims at ironing out such issues by allowing the various actors involved in the design process to work concurrently, in parallel, and on the same platform. This makes this whole very efficient, and ensures that the works of various designers is fully coordinated at all times, and avoids multiple iterations and back-tracking.

When it comes to the design of building envelopes, through this integrative approach, the façade designer is able to work in tandem with the sustainability consultant, for instance. The latter can carry out building physics study in real-time, as the façade is being designed and documented. Similarly, the

12

WFM | SEP - OCT 2018

structural analysis of the façade elements and the incorporation of night lighting components can both be realised in conjunction with the model-building process on the BIM platform.

PARAMETRIC MODELLING One of the buzzwords that has hit the construction industry in recent times has to be “parametric modelling”. While many talk about it, few actually implement it. The idea of parametric modelling is simple: set a certain number of variable parameters in relation of the component being designs (e.g. window-to-wall ratio, panel modulation, building orientation, visible light transmittance, etc.), assign a certain range to these parameters, then have the design software work out the resulting designs for each incremental variation of these variables, and finally, extract the ideal solution

(it could be the one offering the slimmest members, the best thermal performance, or the lowest cost, for instance) from this collection of possible design approaches.

While often associated with highly organic and complex geometries, this technique can actually be applied to virtually any type of development or building component, regardless of its complexity. It allows building designers to make highly informed decisions rather than guesstimating the ideal situation.

REAL-TIME RENDERING Architects and designers who are in their forties and above surely remember how painstaking the rendering process used to be not so long ago. It took extremely careful planning before starting the production process, as the latter would take several hours, if

Smart Design Tools not more, and any mistake would take the same amount of time to correct.

This is all changing at a rapid rate with the arrival on the market of realtime (or near-real-time) rendering software. As the designer builds the BIM model, adding, removing and shaping components, the rendering software updates the visualisation instantaneously. The benefits are clear. Architects and designers are able to view the rendering immediately, for comparison with their mental picture of the project.

Similarly, clients can navigate the project at all stages, enabling prompt decision-making, and speeding up the approval process.

In terms of façade design, in particular, many material suppliers

(glass, cladding, paints, etc.) are hopping onto this bandwagon, allowing the software producers to make the results as close to reality as possible. This means that the visualisations generated are highly photo-realistic. Since it is possible to test multiple combinations of materials and finishes in real-time, I would not be surprised if VMUs, which currently stands for Visual Mock-Ups of façades, eventually turns out to mean Virtual MockUps. VR/GAMIFICATION The newer generation of designers, who belong to the Gen Z or Millennial generation, have a completely different approach to the design process.

They are much more techsavvy, and rely extensively on computers. In parallel, they tend to have shorter attention span and become more easily bored than previous generations. These are generalisations, obviously, but they highlight the need to adapt work methods to these younger designers.

Queue in virtual reality: using dedicated goggles and other accessories, designers can fly through the model and interact with it, literally building a model while being visually immersed into it. This approach is reminiscent of video games, whereby the creation process is much more fun and interactive, thus the nickname of “gamification” of

Smart Design Tools the design process. Beyond the creation process, virtual reality is increasingly appreciated from developers and investors, as they can experience the completed product even before the start of the construction works on site.

AI PREDICTIVE DESIGN A term first coined in in the early 1940’s, artificial intelligence (AI) is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans. The term "artificial intelligence" is commonly used when a machine mimics "cognitive" functions that are typically associated with the human mind, such as learning and problem-solving.

In the context of building design, AI refers to emerging design approaches, where dedicated systems are fed very large amounts of information from existing projects and other sources, this information is digested and “learned” by the system, such that it can then assist

designers in making very quick, informed decisions regarding the best possible design directions to adopt. Using the 80/20 principle (80% accuracy based on 20% of the effort), architects can obtain answers from AI systems regarding optimal building orientation, site layouts, window-to-wall ratio, sunshade arrangements, material properties, and an incredible array of other information. This is all produced within just a very short time (typically one or two hours, depending on the size of the development), and backed by proven facts and experience.

FINAL WORDS In summary, there exists a host of new technologies that are starting to make headways in the design of façades, improving both the quality and the efficiency of the design process. Resistance to change is inherent to the human nature, but embracing these advances is essential for façade designers who do not want to be left behind.

uPVC Windows and Doors Current and Evolving Market Scenario in India

O

ver the past 15 years, India has witnessed an exceptional growth in the real estate sector. With more urbanisation, construction of smart cities, changing lifestyle due to emerging middle class are a few factors that have given a push to new building technologies and materials. uPVC (unplasticised polyvinyl chloride) is one of such building material that has gained attention, as replacement to other traditional materials, uPVC is a low maintenance yet effective material in making windows and doors.

In the last couple of years, we have seen increasing demand of

18

WFM | SEP - OCT 2018

uPVC windows and doors due to the host of benefits uPVC offers.

Now the consumer is well aware of the fact that uPVC is an outstanding material for windows and doors as it performs exceptionally in diverse weather conditions. uPVC windows and doors provide efficient thermal insulation and help in energy conservation.

Not only this, uPVC windows provide high sound insulation with properly fabricated windows and installations. uPVC windows and doors are available in various designs and styles that can match any modern architecture and can be installed in any kind of building, be it villas, high-rise apartments, offices, hotels, hospitals, etc.

They are also available in various colour options that can add value to your home interiors/exteriors.

Surprisingly, you don’t need to be bothered about the durability, thanks to its uPVC compound properties - window and door profiles are termite resistant and practically last forever. uPVC is considered to be an intelligent investment and excellent buying decision as they do not require any repainting and maintenance. They do not rot, warp or corrode, profile colour remains same in any weather/climate conditions, be it summer, winter or monsoon. These window and door systems have proven their effectiveness even in tropical and

salty coastal climates. Windows and doors made of uPVC are environmentally friendly products as there is no wood in it and can be recycled. There are companies which manufacture the profiles with their unique compound material which is 100 percent leadfree and supports sustainability.

The current Indian window and door (all material) market is around INR 14,000-15,000 crore and the market share of uPVC window and door profiles is about 8-10 per cent. As per report by Ken Research, over the next 10-15 years uPVC window and door market is expected to grow by 30 percent with new and replacement sales, major drivers of this growth would be large high-rise apartments in

20

WFM | SEP - OCT 2018

expanding metro cities.

We all know that overall Indian window and door industry is not organised and there is no specific standardisation and guidelines, uPVC is not different from this.

Growing popularity and demand of uPVC windows and doors have given opportunities to many local and Chinese companies to venture into this industry. As India is a price sensitive market, these companies often compromise on quality to earn more profits, which in result creates a bad image of the product.

To avoid this situation, more efforts are required from responsible and reputed manufacturers to make this market organised by standardisation of quality and product specifications.

It will help the market as a whole to protect the interest of the consumer and manufacturers. On one side, consumer will get the quality product at a competitive price and on the other side reputed manufacturers can practice their business in a good atmosphere as most of the companies who are compromising on quality will eventually have no place in the market.

India is a diverse country with various cultures, lifestyles,

Fenestration Feature architecture and different climates. Here you can see summer, monsoon and winter at one place in a year. Every place requires a different architecture of home as per the local weather conditions. The north region faces harsh cold and summer, mostly north eastern region is of tropical condition, and west and south remains hot and faces high rain during monsoon. A couple of years back there was no single material for their window and door that could remain effective throughout the year. But not anymore, availability of uPVC is an answer to this diversified window and door requirements, providing relief to the fenestration consultants who used to struggle against questions like thermal insulation, water tightness, sound resistance, look and appearance and durability. Now they are in a position to recommend world class products, i.e. uPVC to the consumers who are looking for comfort, better lifestyles at competitive prices. uPVC windows and doors come in a variety of styles like casement (outward and inward open),

tilt and turn, sliding, slide and fold, lift and slide, top hung, etc. which complement the modern architecture in a unique way.

We are very optimistic about the future of the industry. The announcement of 100 smart cities, growth in infrastructure, increase in FDI and growing middle class give a clear indication that uPVC window and door market will get more opportunities and grow at a good rate. Published reports suggest that the market would grow at a CAGR of 7 percent during 2015-2020. With metro and big cities becoming noisy and polluted, uPVC windows and doors are expected to become a priority for people thinking about constructing new homes or renovating their existing ones.

The major drivers of the Indian uPVC window and door market are increasing new housing construction and replacement activities, which have contributed to the growth of this market. With the growing number of façade and window consultants in the country, the industry will mature and stress on the quality rather than going for cheap quality material. At the same time, this segment needs more informative campaigns to create further awareness.

Façade Lighting and Shading

T

he beam of light in a room with a country tile roof – the small glass tile would fill up the room with divine light. This small little source of light would make a room lively on a gloomy rainy day. My childhood memories of the light filtered through glass are associated with this little tile that would let in the ethereal light on a full moon night and also the first beam of sunlight in the morning like a wake-up call.

In a way the natural light through a fenestration has always been magical and adds great value to the space enclosed. Considering the climatic conditions in India, surface area and the fenestrations of a building play a vital role in providing adequate light and cross ventilation for habitable spaces.

24

WFM | SEP - OCT 2018

It is the spatial experience in the building that adds value to the moments of life. Harnessing the Sun’s energy to fill the space with diffused light becomes a challenge for the designer for any project.

In the current scenario of following the west, glass has been used rampantly without giving a thought for the comfort and quality of light required for the users in sunny places like India. I don’t want to put the blame on the material.

But the material glass if used wisely it can help to experience the natural elements like air, rains, shadows, patterns, sun light and the moonlight too. Controlled environment within built forms restricts one from exploring the perpetual changing cycles through days and seasons.

Heat loss through glass facade is inevitable considering the

convection currents set in due to hot and cold air temperature difference. Such a condition is not comfortable for cold regions, but in India except for the northern region skylight with vents is very effective to set in convection currents for the escape of hot air and replacing with cool air.

Glass envelopes for large spaces in commercial or public buildings are advantageous. The entrance foyer with a glass atrium spreads good quality of light and also helps to grow healthy interior landscape in large volumes that makes the space livelier. Such large volumes can be covered with laminated glass with light weight supporting structure.

ost of the airports have large facades clad with glass.

Such surfaces with large volumes are difficult to reach for everyday cleaning and hence the need to provide for low maintenance glass. The surfaces of these glasses are designed such that they do not need to be cleaned very often, but can be done sporadically. These are especially useful for flat glass roofs - in difficult locations to reach. The chemically treated glass prevents contaminants bonding to the surfaces.

Any building that has a need to cover a large volume with diffused light could be covered with translucent PVC polyester membrane. These roofs can span across large volumes with lighter supporting structure and elegant forms. This material could be put to use in combination and composition with other materials like glass, metal sheet, and concrete and also with bamboo or wood.

Membrane roofs have advantages over other rigid building materials of being flexible and leakproof.

Depending on the need of the volume to be enclosed, there is a wide choice of colours, meshes, translucency, and opacity, opaque and in varied materials like Teflon

godown to an umbrella/a tent for a single man.

Since ancient times various kinds of blinds, louvers and perforated screens in a variety of materials like stone, fabric, metal, wood and cane have been explored by the master builders. Now we have the new technology and state-of-the-art materials to take this further into new buildings instead of restricting our creativity by following blindly.

For this space to be lit up well, a central skylight with reflecting mirrors lets in pleasant diffused day light.

Now with IOT, one can operate this remotely to adjust the angle of reflective mirrors on the roof top.

One cannot think of the facade as a standalone element of a building, it has to be a holistic thought for the proposed design. As architects and designers, we will have to embrace new technology and innovative applications

with an open mind. This will definitely add value to the new ism in architecture and a pleasing experience for the dwellers in these new carapaces.

Special Feature

Façade Audit F açade audit or forensics is an emerging specialised service that does a diagnosis of the façade design at a micro level. The purpose of this service is to identify the weak links in the façade design and implementation before a disaster can destroy the building envelope and endanger lives of occupants and also people near the building.

Façade is a dynamic industry where there is continuous learning and innovation. Due to this dynamism, there is a fair amount of experimentation that happens at most project sites.

Sometimes things do not work out due to the lack of past data or experience on the performance of the façade. Unlike concrete, where there are volumes and volumes of books and references, façade is a neglected field when it comes to documented knowledge and technical approach as virtually every building has a unique bespoke façade. The information and learning remain with the people on the project and so it remains with the very few.

Having said the above, only the experts understand the micro details of doing a very good façade design and execution. However, the reality is contrary due to this fast expanding industry which entrusts important decision making in hands of people who are not fully experienced yet.

The reasons for failure of a façade are many and a few are discussed here to understand the importance of taking corrective measures at

32

the right time.

A building façade is a reflection of the identity of the developers and the architects, who have conceived the project and give it its existence.

If a façade fails, it not only leads to huge loss and material waste but it harms the prestige of its creators.

What does façade audit mean to the customer and when should it be conducted?

Audit can be conducted at various stages. When the concept and design have been frozen, an audit of the budgeted cost and the detailed design will bring to surface the actual cost of the project by breaking up every component and activity into a cost structure along with design review.

Once subcontractors have been

appointed and have produced design drawings, calculations and thermal models, a full technical design audit will be completed by the façade audit team of the contractor’s designs. The audit consultant will undertake drawingspecific reviews, checking to help see that the relative designs conform to the specification and the client’s requirements and that the design will meet all the technical, lifetime and performance requirements of the project. At this stage, it is not only the façade design that gets reviewed but also the suitability and adaptability of the substructure gets reviewed. This will be a very handy tool in hands of decision makers when they invite quotes and also in understanding the

Figure 1: Roof failure due to wrong design

Special Feature intricate details of the faรงade to take an informed decision. Quite often decision makers are not clear of the minute details in a faรงade as it is an extremely complex tailor made solution and thus squeezing the cost to fit the budget leads to quality compromise that goes unchecked till the day disaster strikes. Audit of design and cost at pre-finalisation will help alter the design in a manner that will not compromise with the safety and integrity of the design as well as offer a correction to the budgeted cost.

Second stage of audit is when the work is in progress. The materials being used by the faรงade contractor are checked in conformity with the tender and the design codes mentioned in it. Any deviation has to be immediately debated and corrective action should be taken accordingly. Further the installation and fabrication methodology are checked from factory to installation at site and any faults that may lead to long-term quality compromise is resolved.

Third stage of audit is at the time of completion of the project to ensure that the work has been completed in conformity of the methods agreed previously and if any corrections are needed than they are advised.

The fourth stage is post completion when building is fully functional and perhaps a few years into service and problems start to surface like in Figure 1. This type of problem occurs mainly in building that did not have the systematic audit conducted as explained above. That is the time forensics comes into picture to identify the root cause of the faรงade failure and provide solution to rectify the defects.

Faรงade failures are not just limited to collapse, crack, excessive water or air infiltration. Building faรงades that do not comply with project specifications, governing building

Figure 2: Glass panel and railing failure due to excess Nickel Sulphide in glass

codes, or industry standards have also failed. Even faรงades that do not meet aesthetic standards or the desired appearance may also be considered to have failed to the owner or architect.

Considering the complexity of contemporary faรงade systems, understanding why they fail to perform as expected is seldom an easy task. Failures can originate from a wide variety of influences, such as accumulated differential thermal or moisture expansion, inadequate wall cavity drainage or material incompatibility as in Figure 2. Complicated internal leak control systems or intricate connection or support mechanism further increase the probability of faรงade failures. Special diagnostic techniques and tools are needed to properly identify faรงade failures to enable effective remedies.

UNDERSTAND PERFORMANCE CRITERIA: When the envelope fails, it is important to have an understanding of how the system works so you can consider what could have gone wrong as in Figure 3. A basic knowledge of components and properties can help you lay the necessary groundwork and map the crime scene.

From a building enclosure perspective, there are six key performance points to consider, and each of those leads to specific failure paths.

Water penetration: The first function of the envelope is to keep water out, whether thatโ s wind-driven rain or general moisture. Water can cause mold growth on insulation and corrode structural element. The most

Figure 4: Moisture penetration due to faรงade failure

WFM | SEP - OCT 2018

33

Special Feature important failure in faรงade is water penetration which can be related to poor execution as well as poor maintenance. There are thousands of places where sealants and gaskets try and stop water penetration and the likelihood that all are performing perfectly is low as seen in Figure 4.

Air leakage: The flow of conditioned air out of the building or the outside air through the envelope can lead to excessive heat loss and high energy bills. There is also potential for condensation if humidified interior air goes out or you are pulling humid outdoor air inside, additionally, air leakage can cause pressure differences and wind drives the rain to be sucked inside.

Vapour diffusion: Although a little harder to understand, this property is as important as the others, because it also presents the possibility of condensation as in Figure 5.

Imagine two rooms side by side that have different humidity levels, unless there is a vapour barrier between them, the two humidity levels will seek to equalise, and the interior wall cavity will suffer.

Insulation: The insulation layer acts as the thermal barrier. Its aim is to prevent excessive exchange of heat from one environment to another. If insulation is damaged or missing, it can lead to occupant discomfort, draftiness and temperature difference.

Differential movement and structure failure: This term refers to outside factors like wind loading and also entail the thermal expansion and contraction of certain building materials, such as masonry or concrete.

The enclosure is all tied back to the base structure, and it has to accommodate for some

34

WFM | SEP - OCT 2018

Figure 5: DGU failure leading to condensation

Figure 6: Glazing bead failure leading to air and water leakage

movement between itself and the base structure, differential movement beyond limit can lead to breaches in one of the barriers and cause performance problems or structural failure as seen in Figures 7 and 8.

Fire safety: Safety of design from risk of failure of building during fire is often the most neglected aspect of a faรงade design. There are numerable incidents of fire which have destroyed building within minutes of the fire because of wrong choice of material and wrong implementation of design.

Fire safety is a vast topic and cannot be covered in a short article but a small case study below will explain the nature of fire spread in a building when the design has gone wrong.

Case Study

Grenfell Tower, London

J

une 15, 2017 -- With 72 confirmed dead but dozens of people still missing in London’s 120-apartment Grenfell

Tower.

Around 500 people were in the building when the blazes started on the fourth floor – as many as 200 people are missing.

Design specifications seen by the Press Association suggest the renovation work carried out at Grenfell Tower included plans for aluminum cladding with a 50mm “ventilated cavity” to vent moisture next to 150mm of Celotex FR5000 insulation, which has a Class 0 rating — the highest rating for preventing the spread of flames.

Fire investigators are focusing on the cladding. Experts believe this may have failed with the void between the aluminum panels and building ACP acting as a chimney and fuel to spread the fire.

36

WFM | SEP - OCT 2018

The aluminum composite panel cladding (ACP) is basically made of three layers, out of which two layers in front and back is aluminum sheet and the middle layer is polyethylene. Polyethylene is a high flammable petroleum product Under severe fire conditions, timber chars, concrete spalls, steel melts, glass breaks.

But Polyethylene, is a plastic, a petrochemical product. It behaves differently than most building materials.

It is fuel !! ….and it burns !!!

Tall building façades clad with ACP panels which have polyethylene core can potentially transfer a fire, very quickly from one floor to the next, with terrible consequences.

Equipped with this basic understanding of envelope science, you’ll be able to take your knowledge into the field and prevent possible failures.

Understanding Testing of Façade Materials for Fire Safety

W

ith the increased number of instances of fire on cladding around the world, just about everyone in the construction industry wants to talk about “Fire Testing”. Testing and test reports have been used for decades across industries to showcase capability of organisations to produce superior products and materials. This article aims to add clarity of vocabulary and implications of the tools used to demonstrate the properties of materials used to create fire safe façade systems.

A test report is snapshot of the

behaviour of specific properties of a given “sample” of material that may have been produced only for the purpose of testing.

There are several properties that explain the reaction to fire and when “samples” are tested for these specific properties we get specific “test reports”. Typical properties that are important to façade engineers designing fire safe facades are: the temperature at which a material can catch fire (known as Ignitability); the amount of heat (energy) released when material burns or combusts (known as calorific value or heat of combustion); rate at which the flame travels across the surface

of the material once it catches fire (known as flame spread) and physical reactions to fire (like smoke and droplets released).

See Figure 1 to see a table used in Europe to quantify the reaction to fire behaviour of (façade) materials.

A valid and usable test report must capture the following: 1. Accreditation or authorisation of the lab for conducting the test. Bodies like National Accreditation Board for Testing and Calibration Laboratories (NABL) or United Kingdom Accreditation Service (UKAS) follow a uniform method (as

Figure 1: The table used in Europe to quantify the reaction to fire behaviour of (façade) materials

38

WFM | SEP - OCT 2018

Fire Safety per ISO 17025) to evaluate the capabilities of the lab to test and report given properties.

Without this traceability, a test report is equal to unsigned handwritten note on paper saying, “I promise to pay the bearer a sum of two thousand rupees”.

2. State, condition and origin (or traceability) of the sample used to conduct the test. This is the only part of a test report that “may be” used to provide a link with any other material that is claimed to perform as per the tested sample. If this information is not available, it is possible that the sample given for testing has been engineered (or produced in another location) to lead to specific/ better results when tested.

3. Date of the test report and the version of the test standard against which the test has been performed. Materials tested long ago or as per older version of the test methods can be misleading. It is equal to complying to and older law which has not been amended.

Readers of test reports should not confuse the usage of the term “validity of test report” to link with the manufacturing date of the material supplied. The validity in months or years mentioned in test reports is only done keeping in mind a revision cycle of the test method. Hence, a report issued in March 2016 which could be valid for three years does not mean that all the material manufactured till March 2019 will be the same as tested. This only means that the test standard used to conduct the test, say ISO 1716:2018 (Reaction to fire tests for products -- determination of the gross heat of combustion (calorific value)) might get revised by 2021.

So how does the contractor or buyer of any raw material get the assurance that the material that will be supplied will behave as the sample produced for the test report. This test report may have been submitted as part of the qualification submittal or be part of claim on a product brochure.

There are only two valid means used to get this confidence.

This first relies heavily on mutual trust between seller and buyer.

Here the seller (sometimes) gives

a copy of a test report (which may or may not have the above three points) and submits a proof that the manufacturing facility follows some Quality Management System (like and ISO 9001). If buying products and materials that do not deal with the life safety of people and the potential loss is an amount is bearable by the buyer; this method can be used.

The pitfalls in this process are many and the buyer needs to have a keen eye and depth of knowledge.

The second method is fairly airtight though not fool proof.

Ignorance to link the pieces of information incorrectly can bring the buyer at par with the earlier method described. This method known as certification and listing relies on a third party organisation (certification bodies or CBs) whose job is to methodically offer tools to quantify this trust. These CBs need to have an accreditation as per ISO 17065 to be in a position to offer these services of certification and listing. To establish the much needed trust, they follow a fourstep process shown in Figure 2.

Step 1. A qualified staff member witnesses the production process of the product/material that will be tested. The process and raw materials are mapped and the sample is marked for traceability.

Step 2. The marked samples are tested to produce a test report complying with the three points pointed out earlier.

Figure 2: The certification process

40

WFM | SEP - OCT 2018

Step 3. Post successful tests, the CB starts to regularly audit the quality control processes at the given manufacturing location. This is done to ensure that the products shipped with the traceability of certification (certification mark/unique ID/number) are manufactured in the same way as the witnessed samples were made.

Fire Safety Step 4. After the success, the CB lists the name and identification of the product/ material packing along with manufacturing location and details of the fire tests the material is complying with on their public domain website.

This acts as a buyer’s guide and an important tool for buyers to verify the claims in product brochures or price proposals.

Certification and listing of the reaction to fire properties of façade materials provide the vital foundation for designing the much needed fire safety in the building envelope. This helps façade engineers choose the correct raw materials for their designs.

Armed with this knowledge and assurance or repeatability of reaction to fire properties; façade engineers use their skills to carefully mastermind a system that is able to provide the weather-tightness and insulation as needed. But they also envision what is the total volume of the material with the lowest ignition temperature.

And hence understand if this material does catch fire what could be the total (combustion) energy released and how that would

affect the adjacent materials.

This helps them assess the risk of a chain reaction cladding fire.

This can only be an approximation and hence a large scale mock-up fire test is performed to validate the design theory. Tests like the NFPA 285 or the BS 8414 are used to see a practical behaviour of such designs in case of a fire scenario. See Figure 3.

With the assurance of repeatability of the supply of tested and listed façade materials and validation of the fire safe façade design, the façade subcontractor is challenged to install the repetitive system all over the building and ensuring no errors are introduced that may be amplified due to the repetitive installation across the building.

It is a common practice to have qualified independent third party inspectors oversee the installation process by comparing with the drawings of mock-up, which has been tested as per the large scale fire tests.

In several evolved jurisdictions across the United States, Europe and now in the UAE, these are mandatory legal requirements.

Such unfortunate incidents and the fatalities forever prove to be scarring on the minds of those who have been through the gruesome ordeal and have lost their loved ones, or a part of themselves, irreversibly.

We can reduce the occurrence and increase the safety for an occupant by having strict guidelines like our National Building Code and Local Fire Laws that should be followed and audited yearly. We must also learn and adapt best practices from well-developed markets like Europe, the United Kingdom and the United States of America, and look for emerging trends which can help improve the life safety.

Fire Safety

1. REGULATIONS AND DESIGN GUIDE The Construction Products Regulation (CPR) lays down harmonised rules for the marketing of construction products in the EU. The regulation provides a common technical language to assess the performance of products. It ensures the availability of reliable information in order that the performance of products from different manufacturers in the different countries can be compared.

The CPR represents a continued focus on the safety and other performance aspects of completed construction works and lays down aspects to consider for construction products. The seven ‘basic work requirements’ namely: mechanical resistance and stability; safety in case of fire; hygiene in health and environment; safety and accessibility in use; protection against noise; energy economy including heat retention and a new requirement - sustainable use of natural resources.

Building regulations are minimum standards for design, construction and alterations to virtually every building. They are developed by the government and approved by the Parliament.

Approved documents provide guidance on ways to meet the building regulations and contain practical examples plus solutions on how to achieve compliance and should be read in conjunction with the regulations to provide clarity.

Design guides offer additional assistance in achieving regulatory requirements. Often produced by professional trade groups or associations within specialist field.

Generally 30-60 percent efficiency factors are achieved depending upon the opening angle.

5. GENERAL PRINCIPLES OF AIR FLOW The direction of airflow or smoke flow is an important factor when selecting a suitable vent type.

Basic principles of airflow relative to external and internal temperatures and pressures will determine the optimum solution.

As well as design guidance and best practice, regulations also dictate the hinge arrangements.

6. APPLICATIONS OF SMOKE VENTILATION 6a. Non-residential application Smoke ventilation by window automation in non-residential applications such as commercial, mixed-use, health and retail, utilise both vertical and inclined automated solutions.

Such buildings in the UK are governed

by BS9999 and product standard EN12101-2.

Unlike the free areas required for residential smoke ventilation, the size and design of the building will govern the vent type, orientation, free area requirements and method of area measurement.

We also need to take into perspective - positive and negative loads such as snow, wind pressure when selecting right automation products. The hardware selection should be in accordance to and comply with the specifications laid out by the façade consultant.

6b. Residential application Smoke ventilation by window automation in high occupancy dwellings, which are both private

46

WFM | SEP - OCT 2018

and public, e.g. hotels, apartments, student accommodation, etc.

Such buildings are governed by regulation Approved Doc B design guide BS9991 and product standard EN12101-2.

Automated smoke vents generally fall into two product groups namely staircase AOVs and end of corridor AOVs. (AOV â&#x20AC;&#x201C; Automatic Opening Vents) Free areas can vary depending on region and type of building and a smoke ventilation specialist should be able to help you with this.

6c. Minimum requirement when selecting natural smoke ventilation system Actuators (Chain or Linear) must be 24v DC and tested to EN 12101 part 2.

A compatible control system with battery backup tested to EN 12101 part 10 for backup power when mains power failure is lost.

A Manual Override (MCP) switch, easily identifiable location and tested to EN 12101 part 9.

7. WHY NATURAL SMOKE VENTILATION The issue with smoke In a fire emergency, the smoke usually is the killer and not the fire itself.

Smoke traps heat, reduces vision

and causes asphyxiation. This results in mass panic, often stampedes and possible fatalities in public places like malls, airports, theaters, schools, commercial parks, etc.

These days many if not all buildings are enveloped in glass and aluminium for its many benefits like light transmittance, lowering power consumption by day, providing great views of the surroundings and maintaining the internal ambient conditions.

When the glass facade is already doing so much, then why not make it more useful for its occupants by automating it for the release of smoke and toxic gases in the early stages of a fire. This is beneficial in many ways, the immediate reduction of toxic gasses and smoke levels, increased time to exit the building and improved visibility therefore reduces panic and overall reduces the risk factor for the occupants, fire fighters and the building itself.

building code to have a chapter in sustainability. The automatic venting system on glazing can not only be used for smoke ventilation but also for free cooling, night purge and natural ventilation. There by ‘creating a healthier and safer environment’.

Conclusion: Smoke control systems form a part of fire safety from building owners and adaptive natural ventilation and smoke control are often integrated into today’s modern buildings. Preventative maintenance of these systems is crucial to ensure that smoke ventilation takes place when required and to ensure people in the building have a safe passage of exit. Badly maintained systems are the responsibility of the building owners and prosecutions are on the increase. Newer systems are now becoming more intelligent and offer intelligent feedback of opening and closing operations so that equipment failures often caused by obstructions, can be identified and repaired at scheduled planned preventative maintenance visits, to ensure even higher levels of safety provision.

FAÇADE FIRE SAFETY

Need for Performance Testing & Certification

F

açade is one of the most vulnerable elements of a building, especially in case of a fire incident. With more attention to aesthetics, cost factor, energy efficiency, eye-catching materials, green concept, etc., considerations of fire safety measures have been slipped under the radar. The scenario has become more complex with the unstoppable mushrooming of high-rise buildings which pose a greater fire hazard. In India, there are numerous fire safety related codes and standards, however, they are scarcely followed. Worse is the case when it comes to facades, it is mostly influenced by the pure considerations of alluring appearance and pricing, and is yet to hit the nail on the head in terms of fire safety norms and testing methods. The majority of the population is still ignorant of the performance of the material and design of the façade play a decisive role in controlling or propagating the spread of fire. There is an acute lack of awareness about the characteristics of the façade materials, such as combustibility, smoke release, toxicity, ignitability, etc. that contribute to massive fire proliferation. Therefore, an active involvement of fire experts from design through to construction is very significant to help in deciding the right material for façade and correct use of these materials. Besides, all stakeholders should be thoughtful of the fact that combat against potential fire hazards can only be effective when façade systems/ testings are given due importance.

This article will focus on the holistic analysis of the performance of façade materials, aspects of façade design for fire safety, fire testing of façade materials, the importance of compartmentalisation and more.

here are two main methods to prepare buildings for fire. One is to detect and act (passive fire protection) which uses detectors, annunciators, sprinklers etc., and the second method is to contain and restrict fire in a given location. Here reaction to fire properties and resistance to fire properties are used to contain or create a compartment. This helps in minimizing damage and evacuation to save lives.

IMPORTANT ASPECTS OF FAÇADE DESIGN FOR FIRE SAFETY Correct material selection and system design are the two key elements that form the basis of fire safety of a façade system. Abhishek Chhabra, Market Development Manager, Thomas Bell-Wright International Consultants, says, “Façade engineers designing fire safe cladding system need to know the fire properties of the material being used and their key reaction to fire like ignitability, combustibility, flame spread, and reactions of droplets and smoke. This basic knowledge is used to design a system, keeping in mind the net fire properties when given materials are adjacent to each other.

fire resistant materials, Harish Gupta, Façade Consultant, Habitat n Skins, says that façade is the exterior wall of a structure or simply put a layer over a structural skeleton framework of a building. Its primary aim is to protect the interiors from wind, heat, cold, water and intrusion. Having defined this, fire resistance is very much a part of the principal functions of the building skin. “So a facade must not propagate fire, it must also not let the fire or heat travel from one area to another and it should not disintegrate in the presence of fire for a reasonable amount of time”. He highlights, “It is seen from many building fires that the spread of fire is spontaneous if facades have combustible materials and so every material that goes into a façade must comply with the minimum fire resistance required for an exterior envelope”.

Echoing the same view, Rahul Tyagi, Managing Director, RT & Associates (P) Ltd, adds that the major parameters for facade design against fire safety are that the material should be fire retardant. “In case of fire, it should be a deterrent for fire propagation and even if it gets burnt then it should not release toxic gases.

It should be able to resist fire for at least 1 to 2 hours so that firefighting measures and human evacuation is possible”.

Sreenivas Narayanan, Façade Specification and Compliance Officer, Siderise Insulation Limited -The Middle East and India says, “The compartmentation based on fire and life strategy of the building will need to be followed for façade design. Separation of floors and two different occupants are primary and compartmentation within external façade assemblies like (cladding, stone, grc, hpl) with fire breaks to limit the chimney is also important.”

Facades are not merely for an aesthetic consumption, they are also a sheath of protection from external stigma. The advent of modern contemporary materials has put forth a barrage of innovative technologies

that propound a utilitarian approach without compromising the aesthetics of the fascia. Badrinath Kaleru, Founder, Studio Ardete, puts in, “While designing a facade, it becomes imperative that we meticulously consider the inherent properties of these materials for a safe and efficient facade, considering the properties like thermal movements, the extent of smoke emission, etc”.

IMPACTS OF FACADE DESIGN ON FIRE SAFETY OF BUILDINGS Physical behaviours of types of facade differ since their components, materials, and construction methods are different. Facade design can act as a passive measure to enhance the fire safety standard of any built form, for example – a facade can schematically incorporate rescue lobbies aiding firefighting, says Kaleru. “The challenge is to determine a facade design that trades off both the goals of efficiency and safety whilst allowing room for creative aesthetic decisions”, he adds.

The key idea is to think of efficient infrastructure, not as a technology that is distinct from architecture, but rather as a new set of materials with which architecture can be made. Chhabra too opines that correct design and its

SAFETY MEASURES As per the new regulations and awareness on safety in case of fire inside the building, says Varghese PV, CEO, Glazing and Metal Works, SOBHA Ltd., the following aspects are very important: • A sufficient number of openable panels to be provided (about 10 percent of total vision glasses) to avoid hazard due to smoke in case of fire. This is to help to ventilate the area.

• Fire stops between the floors on the periphery in order to check the fire in the floor itself.

• Enough ventilated staircase or pressurised staircase is a must to provide safe movement in case of fire.

• Discourage the use of toxic materials inside, like normal aluminium composite panel • Provide the sufficient refuge areas as per requirement to facilitate the rescue.

proper installation are as important as specifying the right materials.

The fire safety of the building is dependent on the choice of each and every material that is selected and constructed to be part of the building structure. Any material that is in the direct line of fire and unprotected can propagate fire to other parts of the structure. Facade design needs to be done in a manner that it does not allow the fire to spread from one compartment to another. Gupta, stresses, “Facade as a complete system must not fail when a fire occurs. Even if the material selected is all fire proof or fire retardant, it’s the construction method or the assembly that needs greater attention. Easier said than done, as facade envelopes a building like a skin, in most cases with walls and beams touching it from the inside and the gaps between the skin and the structure are often given less attention, which is where the failure occurs even if the facade itself may be fire proof. A chain is weak only as its weak link and the gaps are the weak points in the facade design”.

PARAMETERS DEFINING PERFORMANCE OF FAÇADE MATERIALS There is an endless launch of new materials and façade systems in the market, however, it underlines the reliability, quality and safety of these products. It calls for proper testing and regulation methods to enable the evaluation of a façade’s fire-spread capacity. Giving the bleak picture in the hands of the manufactures, Chhabra explains that the most unique aspect of (fire) testing of (façade) materials is that the manufacturers can fool anyone easily by providing test reports for their material. This can be done by making a “Golden Sample” pass all the tests with flying colours. And then in the factory, raw materials, recipes and processes could change due to errors or price constraints. Certification and listing introduce surveillance and traceability of supply chains and processes to add many layers of checks.

Cover Story FIRE TESTING AND CERTIFICATION OF BUILDING FAÇADE MATERIALS Fire testing of the building facade material critically determines the viability of the facade in accordance with the context, safety standards, efficiency and the overall environmental impact including smoke emissions and weather resistance. A large scale testing of varied components may decrease the extent of these catastrophes, puts in Kaleru.

A variety of innovative and unique technologies and materials call the necessity of different test methods to gauge the performance of various façade systems/elements.

Chhabra, elaborates, “Properties of ignitability, combustibility, flame spread and other reactions of droplets and smoke are measured using different test methods. One of the comprehensive methods is the Euro-classes classification that uses EN 13501-1. This captures and tabulates the properties of combustibility, smoke and droplet release. Many other test methods like ASTM D1929 for capturing ignition temperature of plastic, ASTM E84 for capturing flame

spread and smoke developed are useful for analysing certain types of materials”.

The certification is generally provided a third party accreditation providers. Eg. Intertek, Certifire, UL etc. These bodies, inspect the materials under production, witness the test and compliance to the standard set and issue certification for the suitability of the application. The certifying bodies also carry out a periodic audit of the certified products, says Narayanan.

The performance expected out of most building materials from fire point is its resistance to fire and not combustibility alone.

According to Gupta, “The resistance time that a material offers counts towards the disintegration of the material, the rate of spread of fire and the valuable escape time it gives the occupant before it is out of control. The facade material should surely not propagate fire.

Further, it should be able to offer a minimum of 30 minutes to two hour fire resistance, depending on the distance from the source of fire calculated or resistance required.

Since it is the outer skin, fire can

easily spread to multiple floors very quickly as there is no scarcity of oxygen in the outside environment.

When we choose the facade material, we must keep in mind that they are non-combustible and should not propagate fire like aluminium composite panels, PU foam metal panels, insulation that is petrochemical based, etc.” He further adds, facade material can be classified based on certain lab tests as ‘B’ class or ‘A’ class and their sub classes. ‘A’ class being the highest for a non-combustible material and assembly with such material is not easy to achieve in a facade.

It comes at a huge cost which the promoters can hardly afford on a large scale. However, where fireproof enclosure is absolutely essential, the specification needs to adhere to ‘A’ class. All material used in the construction has to be fire proof and the structure must retain its integrity for a min of 30 min as per NFPA 285 code for fire resistance of facades. Having said that aluminium has a very poor fire resistance as it melts at 660 0C and anything held by aluminum frames, whether fire proof or not, will disintegrate within a short

There are many ways to check the fire and smoke from spreading to floors or within the same floor

time. “So while specifying fire rated material, one needs to keep the entire assembly in mind and every material that goes into the making of a fire rated facade must have fire resistance as desired,” points out Gupta.

“Physical and mechanical properties like thermal conductivity, thermal movements, etc. give an astute sense of the performance of facade materials during the fire.

Rigorous fire safety tests need to be employed to determine those properties accurately. The surface spread of fire with regards to the combustion of the facade material, the fire spread within the facade material, melting of the internal insulation, etc. are some of the parameters that guide both the

design and the performance of a façade,” explains Kaleru.

Giving an interesting view of the performance parameters, Narayanan points out, “Different products will have different parameters for performance requirements.

External façade materials like cladding will need to have the classification through an EN 13501 test, e.g. non-combustible, limited combustibility, combustible, etc. Combustible materials should not be used on facades. Both Narayanan and Chhabra agree that the net sum property relation to fire needs to be validated using one or more large scale fire propagation tests of the mock-up of a cladding system like the NFPA 285 or the BS 8414 or others.

PREVENTING FIRE SPREAD IN A BUILDING The fire properties of a material are an important aspect which can prevent the spread of fire. Materials with low thermal transference and higher fire ratings shall be used to enhance fire safety. “Additionally, a facade can act as a buffer to stop the fire from entering inside the structure while facilitating firefighting,” says Kaleru.

Chhabra explains, “One, correct material needs to be selected, and certification and listing are used to ensure that the correct material is reaching the site. Two, one or more large scale mock-up tests need to be conducted to validate the design of the system which will be implemented at the site”. Lastly, he emphasizes on thorough installation inspection to keep a check on the quality and replicability of the installation.

Use of combustible materials is the primary cause of fire spread.

Floor to floor compartmentation at the perimeter edge of slab and curtain wall (which is also mandated on the India NBC 2016) is important to stop the spread of fire internally. The chimney within the cavity walls should have a fire break or a barrier to reduce the fire spread, says Narayanan.

USE OF FIRE RATED GLASS AND ITS AFFORDABILITY Fire rated glass system is needed only if compartmentalization is needed as a part of the fire strategy of a building, says Chhabra. Fire propagation on the surface of the building depends on fire resistance property of the material used.

According to Gupta, fire rated glass is expensive. “But we don’t have to design the entire facade with it. Depending upon where it is used we can choose between a different rated glass,” says Gupta.

Fire rated glass come from 30 to 120 minutes and more. One may think that 120 minutes is the best,

28

Cover Story

Certification and listing introduce surveillance and traceability of supply chains and processes (Image courtesy, Thomas Bell-Wright International Consultants)

but it is very expensive and one can avoid it with intelligent use.

120 minute glass should be used for escape routes or assembly area segregation, which is rarely a part of the facade. For façade, a 30 minute fire rated glass with a fire rated assembly may prove just the solution. But it’s up to the designer and the client to take a call on the extent of use of such glass on the facade. Also, it makes more sense to see what other elements are used in the facade with glass. If you have consciously avoided any combustible material in the facade than even a 30 minute fire rated glass may give a very good fire resistance to the exterior envelope and also keep the costs from getting ridiculous. It’s worthwhile and high time that developers spend that money on tests like NFPA 285 to understand what they are constructing before its too late.

There is no substitute for a fire rated glass as yet. When you need to see through function and you need it fire rated than glass is the only material that fits the description.

However, Varghese holds a different perception about fire rated glass. Using fire rated glass for the outer facade is not practical

64

as it will cost a huge amount. The difference is like 8 to 10 times, so is the delivery time. “Fire rated glass for exteriors is not important as the inside fire make causalities more by smoke than the fire. We need to have a smart facade which can ventilate in case of fire and smoke inside,” he adds. However, he emphasizes that in case of lift lobbies where peoples movement are restricted during fire and smoke, fire rated glass should be used for partitions which will serve the purpose. This will be affordable too, since the area of each lift lobby partition is very less compared to the facade area. According to Narayanan, if the curtain wall

Cover Story framing is not fire rated, the glass, even if it is fire rated, will not have any effect. I do not think it will be economical to have a fire rated system as a curtain wall for highrise, as per Narayanan.

Talking about the pricing of the fire rated glass, Tyagi says that affordability depends on the importance of building versus fire safety. However, fire rated glass is becoming more and more affordable now due to increase in production and usage, he adds.

According to Kaleru, fire rated glass can protect an area for several hours as compared to the non-rated counterparts, reducing the spread of fire. It prevents an imminent threat to life and other assets. The affordability depends on the type of fire rated glass product and the degree of fire resistance. A wide variety of specially tempered glazing and wired products are available, but they all have a certain limitation. So it becomes really important to understand and conform to building codes that elucidate the use of fire rated products.

ROLE OF FIRE STOP IN FIRE SAFETY A fire stop is a sublime fire protection measure which seals openings and joints in a fire rated wall, minimising fire escalation.

They hinder the transference of smoke and fire through cracks and crevices in walls and floor assembly.

These are available in varied forms and materials like cementitious mortar, silicone, rubber, etc.

Fire stops materials and systems are used to ensure the fire is contained within the compartment created as part of the fire resistance strategy. Any areas like through penetrations and parts of cladding system create gaps and openings in the compartments designed to contain the fire. “Fire stopping systems are tested and listed for specific material combinations

66

and designs. They are needed to be selected and used with extreme caution. A fire stopping system tested in a given combination being installed wrongly or in a different combination can be ineffective,” says Chhabra.

According to Varghese, fire stops play a very important role in fire safety to check the fire and smoke

in confined area/floor of the fire.

Usually, they are in 3 major areas: • Between the floor edge and façade, which will help the fire and smoke to confine to the floor of the fire avoiding spreading vertically upwards to the next floors; • Between facade and cabin partitions, which is vertically

With both vertical and horizontal fire compartmentation requirements of this fast-track project, the specification of SIDERISE CW-FS 120 firestops has provided the façade contractor Alumayer India Pvt Ltd and Alufit (India) Private Ltd with a solution that could maintain a fire and smoke seal in one product preventing the passage of flames and noxious gases passing from one floor to the next and also for vertical compartmentation.

For the two residential towers, the façade contractors installed circa 5000 LM of SIDERISE CW-FS 120 firestops including horizontal (floor slab) and vertical compartmentation.

Smoke Stop & Fire Stop There is a common misconception between the smoke stop and fire stop. Both are different. The fire stops are an expensive product and are essentially put in electrical shafts to seal at floor levels or are between compartments above the false ceiling level where services cross. But when it comes to facades, it’s actually used only on very few projects and a lesser alternative called a smoke stop is used. The smoke stop is much cheaper and only stops the smoke. A fire stop for facade makes sense only if the facade is also fire rated to some extent. So when we do provide a fire rated façade, then we have to use a fire stop to make the whole assembly fire retardant. Fire stop or smoke stop is the filler material or construction between the façade and the structure. Vertical or horizontal, all facades will have gaps at interface junctions and this is where the smoke and fire stop needs to be used. It acts as the barrier for fire or smoke to travel from one compartment to the other adjacent or vertical compartment.

SIGNIFICANCE OF COMPARTMENTALIZATION IN STRUCTURE Compartmentalisation in the structure is incredibly crucial for the containment of a fire hazard and allowing for a safe egress to the nearest exit point or a rescue lobby. It is the measure that will stop the fire from travelling from one zone to the other thereby preventing the spread of fire.

Kaleru, says that the basic idea is the subdivision of a large internal space into multiple microcosms by fire rated partitions to impede the spread of fire, flue gases, heat, etc., limiting the damage caused to a building and its contents.

“Compartmentalization depends on various factors, including the fire load of a building, availability of the sprinkler systems, the height of the building, etc.”

As per Gupta, “Compartmentalisation is absolutely essential. Fires must be contained in the original compartment it started as far as possible, preferably for minimum 30 min if not 2 hours in an ideal condition which allows enough time for occupants to escape and the fire authorities to extinguish the fire. If not contained, fire can destroy the entire building within minutes as has been seen in many

Compartmentalization helps in restricting the spread of fire in the building, it localizes the fire and helps in early detection and firefighting. It also ensures that people are evacuated safely from other areas, says Tyagi.

AWARENESS ABOUT FIRE SAFETY NORMS AND STANDARDS Globally, the awareness of fire and life safety has multiplied in recent time. The stakeholders have been very cautious in choosing the right products with tested systems and accreditation.

The installation of the tested systems has to be installed rightly on projects which are also monitored closely by the stakeholders, says Narayanan.

In India, awareness of the dangers of fire is there, but the approach to prevent it is absent. There are strict fire prevention and firefighting norms like sprinklers, fire doors, wet risers, fire alarm system, smoke detectors, fire escapes, etc. Fire rating for facades has remained fairly absent from building regulations even though there are codes and tests as per BS 8414 part

A and B and NFPA 285 and that is the reason no one following it.

Gupta gives an interesting insight that when it comes to façade, the fire regulations are virtually silent about being strict and gives a free hand to developers and architects to design as per their wish with no authority pinning them down on the fire safety aspect. But it’s high time all stakeholders give it a serious thought as no amount of passive firefighting can ensure a 100 percent fire proof building if its facade is still vulnerable.

Highlighting on the positive development, Tyagi chips in that prominent builders/developers/ architects are very much conscious about fire safety. No building is approved/constructed without adherence to fire safety norms and fire department NOC. The stake holders do realise the importance of human life and the importance of fire safety and invest in it.

But, according to Varghese, many new norms specified in the latest edition of NBC are very difficult to follow word by word.

The builders and architects are very conscious in their approach.

They are finding ways and means

Compartmentalization helps in restricting the spread of fire in the building

to adhere since all are agreeing that the enforcement will be stringent in future. “We are finding these norms strictly applied in commercial buildings and bigger residential projects. Even norms on refugee area requirements are getting high importance unlike earlier”, he adds.

Taking into account the high profile fire incidents around the world, architects, contractors, developers, façade engineers, fire-testing laboratories, etc., are becoming more aware of the need of unified building fire safety codes and standards and hazards of combustible substandard materials. However, the industry has to be more vigorous by organizing more awareness seminars/conferences to address the issues at the highest level and educate the stakeholders of the dos/don’ts to curb the potential fire risks.

Generally, façade design considers the passive design for fire safety and is limited to fire stop and

What are the impacts of facade design on the fire safety of buildings?

The impacts of façade design are very significant and can be hazardous and unsafe by using combustible materials.

The materials used could be due to ignorance or value engineering (VE) options as the façade cost is considered at the fag end of the project. Facade design ideally needs to consider the design parameters for a proper fire stop and smoke seal between the floor and provision for the smoke extraction and evacuation strategy in the event of fire.

What are the parameters that define the performance of façade materials during a fire?

The façade materials and the system components need to be reviewed while deriving the performance of the façade materials. The design should consider the location of the building where the particular material is used along with the system proposed to anchor the material. The system plays an important role in the design of a façade element during a fire.

The fire load is a starting point of estimating the potential size and severity of the fire and the calorific value is considered while considering materials.

and its use as a faรงade element.

As mentioned before the testing should also include the anchoring system which plays a major role in the case of fire. For example - there are cases where the insulation material has been the source of the fire and caused massive damages to the building faรงade even though the exterior faรงade material is non-combustible.

Testing of building material would provide a better insight into the use of the material for a particular project.

How important is the use of fire rated glass? Is it affordable or is there a substitute that most companies go with?

In the projects in the past, fire rated glass was either a wired glass and used in a very small quantity. With the advent of high-rise buildings and complicated structures, the architects have started exploring the refuge area to be with fire rated glass instead of a brick wall and a fire door. The use of fire rated glass should be only for the purpose it solves and bare minimum considering the actual purpose of the glass. Considering the glass to be very expensive, it cannot be used extensively in a building.

8. Check insulation compression in gap

How important is compartmentalization in the structure for fire safety?

Considering the evacuation time for any fire incident which is minimum 16 to 20 minutes, it is evident that the damage escalates the whole building and very difficult to control.

Thus, compartmentalization is very important as the fire is limited and is restricted to the source of fire and the other floors of the building are safe provided the design principles are followed. The damage and the temperatures can go as high as 1600 degrees in just around 10 minutes and the damages could be humungous.

What role does fire stop play in fire safety?

In case of fire, especially in a curtain wall faรงade where the gaps between the floor slab and the aluminium curtain wall are the weakest link for the smoke and fire to travel from floor to floor. It becomes mandatory to seal the gap by providing a material or system to ensure the assembly could sustain for two-hour and take care of the movement of the aluminium grid work which would deflect during the fire. Thus, it is advisable to use a tested fire stop system for the project.

How conscious are the builders/ developers/architects about the guidelines, standards and norms for fire safety?

Most of the builders are conscious of the guidelines and standards, but when it comes to implementation.

There are short cuts taken as the cost does not permit them to follow the guidelines. The issue is very convoluted and it basically boils down to common sense and clearly understanding the fire safety and human nature. Personally, I feel it varies from region to region and needs to be addressed independently.

FIRE SAFE FACADES The Basic Guidelines

T

he importance of facades with respect to fire safety cannot be emphasised enough, especially in the context of the spate of fire disasters globally. Let’s consider the current scenario of urban architecture in India - crowded spaces, little or no awareness about fire safety within occupants and add to this, the chaotic traffic that does little to ensure that external rescue operations are effected within quick time.

Now consider the majority of new constructions where the traditional brick walls with small windowto-wall ratios have been replaced by expansive glass, aluminium and stone facades. Fire safe facades, then become a pivotal aspect of design and final construction. Some of the important aspects are: • Adequate checks to ensure that only noncombustible materials and fire-retardant materials are used • Horizontal and vertical firestops should be in place to check the propagation of fire within floors and vertically between floors • In case of openable windows, the monolithic toughened glass should be installed. Laminated panes should be avoided as these would be difficult to break if need be during fire • All openable windows should be clearly marked with a red triangle, visible from outside • All refuge areas (open or compartmentalised) should be provided with adequate ventilation though the facade, either through an open space or through openable panels.

Although these are just some basic guidelines, eventually the building location, type, size and its potential occupant density will demand additional fire-safety measures, ignoring which can pose a serious threat to the safety of its people. It is also important to note that facades are just one element to be considered for fire-safety, and a holistic conformance to all fire-safety requirements, both active and passive, will determine how safe a building actually is in the event of fire.

The new National Building Code (NBC) 2016 in Part 4: Fire and Life Safety also comprehensively outlines the important criteria and construction guidelines for fire safe buildings.

PREVENTING FIRE SPREAD As the fire incidents at Grenfell Tower, London and The Address TARIQ KACHWALA in Dubai have Director, FG Glass Industries demonstrated, use of co m b u s t i b l e facade elements and lack of fire spread measures resulted in massive loss of life and property. This fire spread through the various floors in double-quick time, primarily through the facade. We need to learn from these disasters. Other incidents such as the recent fire in Beaumonde, Mumbai prove that the use of non-combustible facade products can greatly inhibit the spread of fire and give both people and fire authorities sufficient time for evacuation and fire dousing.

Highlighted below are some key parameters that define the performance of facade materials in the event of fire: Materials used for cladding: Glass, aluminium composite panels, metal panels, fibre, and glass fibre reinforced polymers, stones and wood are some commonly used cladding materials. The combustibility and charring index of the cladding materials should be assessed during design and selection.

Building geometry and panel sizes: The facade geometry plays an important role in limiting or enhancing fire propagation. Horizontal projections act as flame deflectors and one larger panel sizes required larger deflectors. Typical U-shaped facade geometries could also fuel rapid fire spread.

The space between buildings: Fire can spread through building exteriors either through conduction (direct flame contact) or through radiation (if the radiation heat flux exceeds the combustion point of the cladding material of the adjacent facade). This is an extremely important point, especially in densely built Indian metro cities and requires additional

Cover Story protection such as the use of fire-rated glass walls instead of conventional glass walls.

Voids or cavities between the facade and the curtain wall: Voids spaces or cavities between the facade and the floors need to be completely sealed through the use of perimeter fire barrier systems. These systems typically consist of firestop sprays, smoke seals and rock wool insulation to ensure that the cavity is completely sealed and to stop the vertical spread of fire between floors, for the duration as required by the fire department or building codes.

IMPORTANCE OF USING FIRE RATED GLASS Fire rated glasses are increasingly becoming the material of choice in creating fire-safe compartments, floors, facades and server-enclosures owing to their durability, ease of maintenance, aesthetics and transparency. Today, lobby glazings and office compartment partitions are almost entirely constructed of glazed partitions and glazed doors instead of the traditional steel and brick-andmortar constructions. Not only do they enhance the livability index for occupants by providing a sense of openness, but they also play an important role during fire rescue if they remain transparent during fire (transparency in fire conditions should be an indispensable part of fire rated glass selection).

Having said that, glazed doors and partitions typically cost higher than a traditional brick wall or a hollow metal door and in my experience, there have been several instances where fully glazed systems have been overlooked owing to their cost.

Using alternate materials is an architectural and cost decision, however, at all times it should be ensured that the fire rating should in no way be compromised through the use of substandard or non-tested systems.

COMPARTMENTALIZATION IN STRUCTURE FOR FIRE SAFETY Compartmentation within floor plates is an extremely critical part of passive fire safety in any construction and in no way should be bypassed or avoided. NBC 2016 has laid out comprehensive guidelines on the construction of compartments (Section D-21) and these compartments should have a fire rating of two hours. Irrespective of the cladding material used, these compartments should provide comprehensive safety and serve as a completely protected refuge area. In cases where the compartment walls have to be penetrated

for electrical ducting or plumbing, adequate precautions such as collars and wraps should be used to ensure complete compliance with norms.

AWARENESS AND IMPLEMENTATION OF PASSIVE FIRE SAFETY We are witnessing a very positive and upward trend with respect to both awareness and implementation of passive fire safety in building construction. This trend has resulted due to three factors: first, stricter requirements of the local fire department and nonissuance of No Objection Certificates in case the rules are flouted; second, popularisation of NBC 2016 through workshops and its comprehensive focus on fire safety and third, increasingly demanding corporations and occupants, which results in a positively competitive environment between developers to sell fully compliant structures to their tenants and buyers. Having said that, there is also a great scope for improvement in compliance, as these trends are typically observed in tier 1 cities and in areas where real estate prices are high. It is the responsibility of all stakeholders in the construction space, developers, architects, consultants, engineers, material suppliers and even occupants ensure that adherence to these safety norms is respected and implemented. We should learn from the unfortunate and fatal fire disasters in buildings and should be collectively responsible for the protection of life and property when building new spaces for education, healthcare, living and working.

ell us briefly about your company, your journey and the milestones achieved over the years?

Uniglaze has started production in October 2017, our aim is to make Uniglaze India’s most trusted, innovative and technologically-advanced building facade company. We are already executing projects in in Bengaluru, Chennai, New Delhi and Kolkata.

Prior to starting of Uniglaze, I was in my family business of real estate development and concrete products manufacturing. We were looking at backward integration to manufacture facades and windows for our own projects. But, post studying various factories in Europe and the Middle East, and doing a detailed market survey in south India, we realised that there are a very few players in the market who provide quality façades and windows. Based on this, we set up the first automated plant for façade manufacturing here in Bengaluru.

In less than a year, our company has more than 115 members on our team, The largest project we have done so far is a 32,000 sq m job, the North Gate IT SEZ project for the North Gate Developers, which was completed in a span of four months. We have worked

with Olympia Developers, DLF, Brigade & Sattava Group too. The North Gate and Olympia Tekno are our completed projects.

If you look at in terms of unitized curtainwall, we can produce up to 130 to 150 sq m unitised panels per day.

Tell us about your company’s facilities, structures and production capacity?

Our factory is located in a twoacre land in an industrial area at Malur, which is about 40 km from Bengaluru. We have 45,000 sq ft of covered space, accommodating an automatic line and the entire supporting machine. We have materials handling equipment, a dedicated conveyor system for glazing, and temperature control room for silicon applications. As a company, we are in the final stages of SAP Implementation that would help us bring in better control to our processes.

It is one of the most modern manufacturing facilities.

The installed capacity is between 150,000 to 1600,000 sq m of curtainwall production.

What are the product categories offered by Uniglaze?

We are into curtainwalls, both unitized and semi unitized, aluminium composite panels, and windows and door industries.

We are also doing claddings like MS Structures, mesh work, canopies, solid aluminium sheet etc., based on the requirement of the project. We provide complete solutions for façades.

Our major work is in the curtainwall category. In window category, we are only doing Olympia Good Wood Residences in Chennai and Myra home in Bengaluru. We are doing only two projects in the category - door and window. But predominantly 80 to 90 percent of our business is façade related.

Where are you sourcing the machinery from?

All our Aluminium processing machines are from Italy and USA.

Industry Speaks Our metal working machines are from India. The tools and equipment are from multinational makes.

Shop floor of Uniglaze factory, having 45,000 sq ft of covered space, is located at Malur, which is about 40 km from Bengaluru

Automatic machining & cutting centre-machine shop. Main feature of this machine: Multi Spindle machining unit; automatic loading & unloading magazine; bar feeder and profile pickup system; one unitized panel complete machining can be completed within 5min.

Could you please tell us about the company’s structure?

We have a board of directors comprising of Subhas Chand Kankaria, Ajit Chordia and myself.

I look after the daily operations as Managing Director of the company.

We have a GM - Operations, and under him each department has managers. The company has 115 people on the payroll.

All the department heads have been delegated decision making powers for the smooth functioning of the organization. We encourage them to be proactive in decision making and review the same in weekly structured meetings.

As a façade company, could you please tell us about your specialties, your approach to the business and the products?

Firstly, we work closely with the clients. We help the clients make an informed decision by educating them on the quality and standards of windows and façades, and giving a checklist to check our products, which is as per European standards.

Secondly, we are the first company in India with state-of-the-art automated plant which makes us capable of maintaining the level of quality and yet have high production capacities. The machines have been imported from Italy. We have invested heavily in technology and on building the right team, which I feel is very critical.

Please brief about the various steps in executing a project?

Firstly, we submit the documents to the client and our bid for it. Once the project is awarded to us, we sit down with our client and prepare a detailed timeline as what they are looking at and what are the conditions. We do not give any false commitment in terms of timelines. It won’t be

WFM | SEP - OCT 2018

Industry Speaks practically possible to meet the timeline if it is fictional. The micro schedule is prepared. Even if there is a delay, per se, it is brought into the notice of the customers well in advance. Correctional steps are taken immediately.

What kind of role the architects, façade consultants and the fabricators play in your projects?

In the management side, I am directly in touch with architects, façade consultants, key developers, etc. My team consultants and the General Manager are also being directly in touch with them.

Façade consultants play a very important role in every project.

They help to bring in the right standards and quality in the project. Earlier, developers were not fully aware of the requirements like standard and quality of façade materials. A façade consultancy is like a structural consultant. The consultants are the people who ensure that the façade meets all the design requirements. Along with other industry members, they bring in quality and standards for the projects. Their involvement has helped to change the face of the façade industry in the last 5 to 10 years, and how India is progressing in the sector.

How well aware do you think are the decision makers in general about the availability of cladding materials, especially glazing products, functionalities, and categories? How do you help them to gauge?

Nowadays, developers are well aware of different types of cladding materials and qualities. We are able to propose to the architects so that they can incorporate it in the upcoming projects. We know that everyday a new product is being introduced in the market.

North Elevation

South Elevation

Our responsibility is to educate the architects, developers about the types of products, which are available. Architects are keen to look at different materials, but there are certain materials that are always preferred. Developers look out for alternate materials. It is very interesting as each building is different. Nobody wants to repeat it. So we have designed every building, looking at the design and the best suitable products. There are new challenges ahead with respect to installation techniques, lifespan, performance, etc.

Industry Speaks southern Asian countries? The media façade which is the craze now, what are you doing in this segment?

We have tied up with specialized companies in Hong Kong and Australia called Illumination Physics. They have done more than 40 custom designed façade lighting projects like HSBC building in Hong Kong also major buildings in Macau, the Middle East, and Australia. What we are doing is lighting integration in façade, where the lighting and fittings are integrated as part of the design. So if any customers who want high quality facade lighting where all the lights are IP 65 and IP 67, which lasts for over 15 years with LEDs having 50,000 hours warranty, we are ready to provide the same.

Today, all major light manufacturers provide standard light fittings. We are ready to custom design the light fitting which is required.

Olympia Teknos, Chennai - An office complex by Olympia Group

Could you please tell us about the projects you are working on?

Presently, we are executing a few projects including DLF Cyber Parks at Gurugram, Olympia National Tower, Goodwood residence, Brigade Panorama, Brigade Orion Mall, OMR. Brigade Arcade, Salarpuria Sattva Mall, and Express Avenue - Chennai. It’s a humble start for the company. We are looking forward to much greater heights.

You said that some of your projects were very special with innovative technologies and materials, and a lot of R&D going on. Please tell us about those projects?

North Gate and National tower are two such projects where we have given our inputs to improve the end products. Our R&D is an ongoing process because we custom design

82

WFM | SEP - OCT 2018

for each project we take up, in order to minimise the cost of the project.

We are also working in the area of integrating façade lighting.

Today in many parts of the world, like Hong Kong or New York, we see beautiful buildings with fabulous façade lighting. Those kind of facade lighting concept and dynamic lighting are still at a very basic stage in India.

Uniglaze has already tied up with a few specialist companies that offer these services. At this moment we may be able to focus only on a few niche products and projects, but in the coming year, I feel façade lighting would be a good part of our business.

Since you are talking about façade lighting, it is one aspect of façade which India has not progressed like the western or

We are seeing a lot of iconic projects designed by architects.

How easy or tough is it to work with architects and developers who are dreaming to create uniqueness in their projects?

Sometimes, the biggest complaints of the architects are that – “whatever we design, façade contractors tend to say that this design is impossible to achieve”. As a company, from day one of our establishment, we try to provide solutions and to achieve what architects are wanting in their design. As a company, we do not say no to any of the challenges.

We spend a lot of time looking for Green solutions and our design team is very strong. We already have 10 member design team and are adding to our strength every month. Our aim is to provide solutions to the architects and not to look at the easy way out.

Yes, it takes a lot of time, inputs, and challenges to meet them.

We have managed to achieve the requirements of all the architects.

Industry Speaks Can you tell us about some of the customised solutions that you have provided?

In one of the school projects in Chennai, the façade had certain concrete elements. While doing the façade engineering, we realised that the customer is going in a wrong direction with concrete products. Though it was not a part of our production or manufacturing scope, we helped to find solutions for the same and we made the entire detailing of how the concrete panels should be made, how it should get reinstalled, etc.

We did the calculation behind that.

Our team went to the concrete product manufacturing facilities in order to study the requirements and to meet the wind load and dead load criteria. Finally, we got the project done, which was taken over by the client. Though it was not within our scope of work, we got ourselves involved to give a solution to the architects and to the client, in order to achieve the goal of the project.

How important are the selection and the installation of the right cladding material when you look at the conservation of energy, power, and acoustics?

It is very difficult to ascertain the right cladding material because there is always scope for improvement and daily new products are introduced in the marker. Ultimately, considering a developer’s point of view, we have to balance the right material to affordability. To achieve the required range of thermal insulation, there are so many options available. But all of them might not be a viable option. That’s why we do engineering for these products so that we are keeping the cost lower and trying to improve on the acoustics, thermal properties, indoor air quality, etc.

For example, the thermal break system is very normal in western

countries and the Middle East.

But in India, hardly any project has used that, considering its cost.

Selection involves a balancing act, considering the cost and quality.

The thermal insulation requirement will vary based on the geographical areas? How do you take care of it?

Progression is happening in the façade industry. In earlier days, only single glazed glass was used for facades. Soon products like triple glazed glass (which is being proposed now), and better thermal insulation products will bring in a drastic change. So definitely it is going to be beneficial for the client by using better insulated products.

He will be able to save cost directly, not looking at it as a long-term investment. Developers are ready to go for the certification of façade too.

By installing a high performance glass, we are able to save electricity

bill. Now we are seeing a more direct reduction in our capital expenditure for air-conditioning and other things which are easily measurable from day one. People are getting more educated about it. Even the hotel industry is using triple glazed glass because the acoustic level comes down; then if the hotel is on the main road, less noise and the comforts are very important.

Keeping all these things in mind, the developers have agreed to go ahead with what we are proposing.

What is the emphasis on R & D? Is there any testing centres? And what kinds of testing are done on the products?

For performance tests, we already have two labs - one in Chennai and the other in Mumbai. These labs test the standards for all the major projects today across the country.

These performance tests are very critical.

Industry Speaks Secondly, R&D in terms of sourcing materials, looking at the ways for bringing down the cost, at the same time in more efficient systems. We are working on customised façade lighting and façade system. R&D is also towards integration and execution of projects. Another aspect is definitely towards better performance. For example, we should be sure about the parameters and performance level of curtainwalls under various limits. The reports are important to see whether the building is performing or not. Once the curtainwall is installed, and if the engineering and designing are not properly done, one cannot remove the curtainwall and reinstall it. It’s better to invest some time in testing rather than regretting later on.

How do you see the façade industry evolving in India?

The façade industry in the next five years will become more professional and quality conscious. People will understand that façade is an engineering product and a lot of consolidation will happen. People who are doing quality work would go a long way. Manufacturers who are not following the standards will have to change.

Could you please brief on the main challenges faced by the façade and glazing industry?

Inefficiency is the biggest challenge.

It happens at the construction site and in the manufacturing process.

The entire cycle is not very efficient and professional till now. This results in the delay of projects, affecting the fundflow of the project.

Could you please tell us about your company’s contribution to the façade industry?

We are still very new in the industry, trying to find our own foothold. People have noticed the technologies that we have brought in. Being the first in the industry, we

84

WFM | SEP - OCT 2018

are keenly observing and seeing how the market evolves around our type of manufacturing.

Is there a major change expected because of the recent regulations in RERA & GST? Definitely, if the real estate industry is affected, the façade industry will get affected. With the RERA implementation, developers have to provide a five year warranty.

AS a result, the quality standards will improve. The requirements of the clients are more in line with international standards. They are looking at indoor air quality, thermal insulation, acoustics, etc. As we keep moving up in the value chain, quality will play a very important part. Companies which follow high standards will do well and others will struggle. Under RERA, timely completion of the project is critical and developers would penalise façade and window manufacturers if they delay the projects. Thus, quality and time will be critical for the façade industry.

Could you please tell us about your company’s expansion plans and strategies for the future market?

Presently we are concentrating on the Indian market. In the long term, we would definitely like to explore the countries in the South Asian region.

Evening view of North Gate, Bengaluru

At the manufacturing level, we already have substantially installed capacities. We are not doing any more capital expenditure for the next year. But definitely, we keep studying and looking at how to bring down the production cost and bringing in more efficiency in production.

We are only an 11 month old company but have done substantial capex. Except for any small capex requirement, major investment will not happen in the next one year.

What are the strategies to keep your company ahead of others?

Our only strategy is to offer quality products which are superior to others. We have invested in the automatic line, right team, right manufacturing processes, and right installation teams on site.

Our efficiency should speak for us rather than anything else.

Where do you see your company in 2025 and the façade industry in India by 2025?

By 2025 we definitely wish to see ourselves in the list of top three façade manufacturers in the country. I foresee a great deal of consolidation happening in the façade industry, substantially towards more quality consciousness, better design, and engineering in the next five years.

Alstone Water Proof Ply

A

lstone has introduced Alstone Water Proof Ply, for the first time in Asia. The product is manufactured from ingredients like rice husk, PVC, calcium and additives. The uniqueness of water proof ply (WPP) is that it is similar to ply in its feel, smell, colour and touch with incomparable features like 100 percent water proof and termite proof, and has fire retardant properties.

No plywood in this world is water proof and termite proof because of the cellulose content in it. At the same time it is also true that we can treat or season plywood by various techniques and methods to make it durable and enhance

88

WFM | SEP - OCT 2018

its natural resistance against water and termites to some extent.

And this treated and seasoned plywood is being promoted in the market as water proof plywood in the industry. However hard we may try, we cannot give it a life time warranty for these properties.

With the passage of time, it will loose its resistance and be prone to moisture and termite effects.

This leads us to look for other substitutes that can give us the natural feel of wood but with a better and improved version in its durability and functioning. Alstone WPP comes with lifetime warranty of being 100 per cent water and is termite proof. The ordinary plywood has an inherent problem of delamination due to absorption of moisture, which is totally absent in our WPP. There is no chance of delamination as it is made with a single strong layer.

It does not require any special adhesive to paste veneers and laminates like ordinary plywood.

Any resin adhesive is sufficient to give it strength over pasted veneer and laminates which is incomparable to other plywood boards.

The other easy and affordable option is going for direct painting in whatever colour you want. It will give you a pleasant appearance always.

Another strong point is that it is 100 percent calibrated. The ply is

Launches uniform in thickness. Also being a 100% formaldehyde and toxic emission free product , it is the only ply which has been credited by the GRIHA council as a GREEN PRODUCT and hence the best choice in sustainable and green product category.

Unlike plywood, it is not restricted in its usage. It can be used with the same ease in exterior as well as interior applications like wardrobes, modular kitchen to fencing, wall panelling etc.

P

lease tell us about your practice and your ongoing projects?

After completing my B Arch in 1988 from Mumbai's Rachana Sansad Academy of Architecture, I worked under the aegis of Architect Hafeez Contractor for four years.

I started my own practice Sanjay Puri Architects (SPA) in 1992 and my first project was a township.

We have a broad range of design portfolio which includes projects in various typologies, such as hospitality, commercial, retail, educational and residential as well as large urban projects

Reservoir, Ras, Rajasthan - The design is responsive to the site contours, the climate of its location and to the need of its users, generating office spaces that require much lower energy consumption due to their orientation while imbibing the traditional architecture prevalent in the region since centuries and creating a large water catchment area in response to the water scarcity prevalent in the location.

and town planning. Currently, our firm has a strength of 72 people.

All in all, it has been an eventful journey and a learning experience all along.

Some of our ongoing projects are a township of 100 acres in Ras (Rajasthan), another township of 51 acres in Raipur, a textile market in Surat, commercial in Ahmedabad, commercial at Ghaziabad, a bungalow in Lucknow, a club in Ranchi, a University of 30 acres in Indore, a university of 33 acres

The Cresent, Surat, Gujarat – A series of curvilinear corten steel screens on the south east & west sides creates a focal north facing the open courtyard

in Jabalpur, and a school in Aurangabad.

What inspired you to become an architect?

I had a strong fascination for art and was good at it, and fervently wanted to be an artist. Once I had the opportunity to read the book ‘Fountain Head’ by Ayn Rand at the age of 16, which further fuelled my interest in the field of art and

architecture. I believe that book has impacted me at a deeper level that changed my whole attitude and planted a seed of desire to become an architect.

Could you please talk about a few of your projects featuring innovative façade and fenestration design?

I am excited about all my projects and take up all the projects with the same unwavering spirit,

Triose, Lonavala: The building is created sculpturally from within & externally and is a unique manifestation of abstracted volumes that are fluid in the interior and perceived as a dramatic juxtaposition of trapezoidal volumes on the site.

WFM | SEP - OCT 2018

but with a new and innovative approach. Every project is unique and special in its own way. One of the projects which is very close to my heart is the ‘Triose’ at Lonavala, a retail commercial building. As a standalone building, it was very creatively stimulating to work with spaces and forms. The building is created in fluid sculptural form from within and externally and is a unique manifestation of abstract volumes. Angled spaces projected towards different directions and an organically folded concrete skin evoke an exhilarating experience.

As one of my early projects, working on this venture was quite interesting.

Another very worth mentioning project is the Courtyards House. It is a 35,000 sq ft residence project located in Rajasthan. The house looks like an extension of nature, all in exposed concrete. It is designed in response to a climate with long summer months of 450C average temperature. Organically radiating concrete volumes of varying proportions from central, open to sky courtyards create a sculpted series of spaces in this house. This project was completed in 2011-12.

The Urban Fluid House, Mumbai - As a complete deviation from the rectilinear box type structures in the vicinity this residence is created with a flowing fusion of roofs, walls, floor level slabs & balconies running across both vertical & horizontal planes to encapsulate the spaces within its three levels.

Please tell us about your design approach?

If you are a keen observer with a sense of details, you will see each project portrays individualism and character. Every project is designed based on the contextual and climatic references, such as the geographical position of the site or the location of the project, neighbourhood, locally available materials, etc. These key factors are critically analysed when we design the project and our emphasis is on contextual design solutions.

The Origami House, Pune: The house is expressed as a single sculpted volume externally with subtracted volumes within forming the semi enclosed spaces that punctuate the building form. The Origami House is responsive to its context creating privacy from adjacent buildings in close proximity.

Officesâ&#x20AC;&#x2122;63, Gurugram - is a building that generates open spaces at both the community and at the individual level while being designed in the context to its surroundings, the city's climate and its heritage in a sculptural manifestation of form with individual identities to each space within.

106

WFM | SEP - OCT 2018

Face to Face When we look at your projects, the style is so obvious - many of them are designed with stacks of cubes and cuboids. Can we call it your signature style?

Thatâ&#x20AC;&#x2122;s right. In my design, you will find cubes and cuboids stacked at different angles. We do not want to design each floor stacked atop one another, which will look very ordinary and monotonous.

As for the façade of the building, we consider certain parameters - the direction of sunlight, heat ingress, building orientation, etc.

The angular stacking is done looking at design fragmentation to give best results to the user or considering the user comfort.

Architects like Le Corbusier have used concrete to create

masterpieces. We have seen that you too like to design with concrete and play with different forms.

Yes, I like to use only one material in one project. Again, the material which I use depends on the geographical location and the climatic condition. It also depends on the requirement or purpose of the building. The designs and materials used for a residential project in Mumbai would be very different from those used for projects in Delhi or Rajasthan.

So it varies as per the climatic suitability. In Delhi, one needs to consider the direction of hot air blowing in during summers and cold air in winters. Whereas in Mumbai, there is south-west wind, which compels to give attention to ventilation, daylighting, etc.

What are the key factors to consider while designing and installing facades & fenestration?

Every room in the building should get ample sunlight so that the

Infinity, Mumbai - The design creates a residential project based on the requirements fostered by the needs of today being responsive to the climate of the city and alluding to its architectural heritage.

108

WFM | SEP - OCT 2018

occupants need not depend on artificial lighting during the day.

These kinds of designs are nowhere in sight in cities like Mumbai or Delhi now. Every time you walk into a room, you have to switch on the light during the day. How stupid is that? When there is enough natural light and ventilation throughout the day, why should we waste other resources? We need to design more cost-efficient and eco-friendly buildings through the efficient fenestration.

Facades and cladding industry in India has gone through a sea change in the past decade.

Tell us about the latest façade and cladding materials and technologies available in the Indian market and those used in your projects?

We try to use the natural material or locally available materials as far as possible. The design and products should be contextual and regional.

The texture is also important. We have used stone or concrete in most of our projects and still try

Face to Face to explore it. Stone is fire resistant and easy to maintain. We do not use any materials which catch fire easily. We use a lot of stone like products, like the Neolith stone, in our projects. We also use Nexion tiles or granite, but not aluminium composite panels (ACP).

Many of your projects – for example, the residential projects Fiorenza for Lodha Group in Goregaon, and Waves at Bandra, both in Mumbai - look completely different. Could you please talk about your projects?

Waves is a sea facing project. It

has transparent balconies to enjoy the full sea view from every single room. The form of the building too is like waves which is very contextual. It is a glass and concrete building.

Fiorenza for Lodha at Goregaon in Mumbai has a large green forested area towards the west. It is located near Aarey Milk Colony.

We have designed the façade considering the view from each balcony in the building. The building design is very simple.

Please brief on the technical benefits of a well-designed and well-managed façade and how it helps the building to be energy efficient at the same time provide a better interior environment?

While designing the façade, one has to consider the following factors -- the orientation of the building should be in such a way that there is no heat gain; provide all the services on the southern side of the building since there is no or minimum heat gain experienced in the south.

A façade can be managed well, in a much better way, if it is built with or clad with natural materials like stone. Paint or another type of cladding material, which is mostly man made, requires constant cleaning and the maintenance is much more expensive. Natural materials need not require cleaning at all.

Ishatvam 9, Ranchi - is designed in response to the social needs of the residents of the city of its location providing each apartment with 20% open area as extensions to the internal spaces, maximizing on natural light and air with cross ventilation to every room in the house, creating an urban high rise tower that will allow its users the openness of the low rise structures that they have been used to living in.

What are your views on future facades and fenestration technologies and materials?

We all know that many complex façade designs are possible with available materials and technologies. The resources and technical inventions are immense, hence the options for designing and availability of materials are limitless. You can build whatever you dream.

72 Screens, Jaipur - Designed as a corporate office headquarters, the ground level houses a reception and conference rooms above a car parking basement with office areas at the above 5 levels. The entire building has a screen envelope that serves to reduce heat gain in response tot eh climate of its location.

The Bridge & Community Centre, Rajasthan - Designed to engage with the surroundings, the bridge will be made of solid stone below, gradually achieving a lighter feel as it moves upwards. The upper part of the bridge is proposed in a series of cuboid stone screens derived from traditional architecture in Rajasthan.

These cuboid volumes create sheltered spaces to sit on the bridge and serves to become a community space for the residents along with the water front.

According to you, what is an intelligent faรงade?

If you design buildings judiciously in the planning phase, it will definitely turn out into an intelligent building. So, 90 percent of intelligent buildings are accomplished through better planning and design. An intelligent faรงade has to be very flexible and adaptable in a sense that it should be able to easily acclimatise to outdoor environment or weather fluctuation.

Please brief on your projects designed for various geographical conditions?

We did an office building in Jaipur and it is radically different. In the past 10 years, almost all the office buildings built in Jaipur have wrap around curtain wall facades. How can you build buildings with glass walls in a place where temperature touches 500C? And that too in desert weather conditions?

So we chose to have jaalis made of GRC in all sides of the building wrapping the building. The faรงade is designed with Rajasthani jaali, following the traditional architecture. It reduces the internal heat gain by 27 percent. Of course, it is not done in the traditional way, but using abstract methods derived from the original methods.

Face to Face a step well. The site is in the midst of desert land where water is a scarcity and temperatures are in excess of 400C through 8 months of the year. The site is steeply contoured and the land forms a natural water collection pit from the surrounding land. The design of the office is inspired by the form of the ancient stepped wells. Office spaces are created on the two north facing sides gradually stepping down at each level along the existing contours generating north facing landscaped terraces fronting each office. The design generates landscaped spaces, creating a large community space. Most of the building is built underground and the soil protects it from heat ingress.

We are doing a hotel project in Srinagar for the Hyatt group.

The design of the project is worked out considering the geographical condition and the weather, which is entirely different from Rajasthan. In order to have the beautiful view of the majestic mountains, we have provided balconies to all the rooms. The material used for the façade is locally available stone.

What is your advice to young, aspiring architects?

One has to select materials which are appropriate to the locality and suitable for the geographical condition. Usage of more and more glass and aluminium lead to excessive

use of resources than what is required and will continue to consume more energy, thus increasing operational cost.

Vernacular materials are better compared to the one with shiny glazing.

What could be the architecture of future facades?

The architecture of the future facades could be the one which belongs to our country -- using natural and locally available materials. Nowadays, we see a lot of emulation of design around the world, giving hardly any thought on its relevance in the specific location and climate.

It is very important to design according to the geographical and weather pattern in India.

virtually consolidated built-up area of 2,355 square metre spread across four storeys, serves as an office space and storage for a clothing brand. The multi-level office sits in a tight urban setting in South Bengaluru. Underlining refined details that are unobtrusive, the design of the office space is intentionally minimalist, calm and functional, without any extraneous dĂŠcor elements.

The design intent has been to achieve a sense of fluidity in the architectural form that is suited to the client brief. Translation of a sculptural notion into a workable design and construction was a serious challenge that has been bested by the use of digital media and physical models as reference prototypes for execution on site.

The individual cabins flaunt bespoke furniture customised to suit client specifications, while the common workstations are equipped with modular furniture by Featherlite, to maximise seating. The custommade furniture in the cabins is subtly sewn in wood, topped with Italian marble to add a sophisticated look and feel.

Unlike most contemporary projects that use neoteric techniques, this commercial workplace uses generic materials like concrete brick and glass, effectively used to create complex fluidic forms on the exterior and interior. Drawing from

the qualities of the exterior, the interiors aim to accentuate the fluidity of the space by mapping the surfaces in the ceiling and the walls. Malleable materials such as concrete and glass are used in the exterior while flexible ply and solid surfaces are used to create fluidity in the interiors. Flexible plywood is used for most of the surfaces in the interiors, adding lightness and an ephemeral finish. All surfaces are finished in a reflective high gloss paint, accentuating the fluidity which is further augmented by means of a seamless reflective skin using polished white Italian marble. Similar strategies are employed in detailing of the false ceiling and the lighting that goes into it. Sinuous lines of fluidity articulate the ceiling to go with the overall scheme of the interiors.

Subsequently, the interiors and the exteriors form one cohesive whole.

umbai, though home to thousands of residential towers, is always open for a fresh architectural idea. When ZZA team suggested to the builder an entirely new approach for the new high-rises, he was more than keen to hear them out. The architectâ&#x20AC;&#x2122;s idea was to use ample sunlight and earthy elements to develop a warm and nature-based personality for the new residential tower, but with all the trappings of modern day luxuries.

The architect assembled the necessary façade components to create a one-of-its-kind architectural icon in Santa Cruz, Mumbai. Various factors had to be deliberated upon to arrive at the final design, including the exterior look.

The builder was in complete alignment with the architectâ&#x20AC;&#x2122;s vision - a play of light and shade, embellished with natural elements like wood, marble and vertical gardens. The greater challenge was in integrating all these elements in a pleasant manner, within budget and tight deadlines. Importantly, they had to be of high standard, maintenance free, easy to install and comfortably mesh with the larger design objectives of the building.

Project Watch QUICK FACTS:

Project Name: Greenfields Location: Santacruz, Mumbai Client: Seasons Architects: ZZ Architects, Mumbai Faรงade Materials: HPL (FunderMax - MAX EXTERIOR 0922 Amazon), Stone Other Consultants: Nitin Shah architects, Sura & Associates Materials used for faรงade & fenestration: HPL, UPVC windows Commencement Date: April 2014 Completion Date: November 2017 The faรงade has large windows that facilitate cross ventilation

The aim was to create a striking faรงade with verticality as its strong concept stands out from its surroundings. The compound wall is also high with green walls and vertical fins to contribute to this concept.

The project consists of two buildings resting on a large podium that binds them together.

The podium has a green garden that provides lush greenery amidst the city life and reduces the greenhouse effect making it sustainable.

The faรงade has large windows that facilitate cross ventilation and minimum walls to maximise the views and provide a strong physical and visual connection between the interior and exterior.

Each apartment is equipped with a VRV facility for HVAC and a dedicated area for services so that the elevation of the building remains undisturbed.

The apartments are finished with marble flooring and a modular

The architect assembled the necessary faรงade components to create a one-of-its-kind architectural icon

kitchen for its residents.

HPL panels used in the exterior of the building provide extremely effective weather protection that is particularly suitable for longlasting faรงade claddings. They are double hardened, scratch resistant, solvent resistant, easy to clean, impact resistant, easy to install and sustainable.

For the faรงade, the architect chose HPL - MAX EXTERIOR 0922 Amazon from FunderMax. It fulfilled all the specifications required of the faรงade. Like the earthy wood finish, its robust feature allows to withstand Mumbaiโ s high temperature and heavy rain and made easy to install.

These features ensured that the faรงade part of the building could be completed on time and within budget.

Marble used on the exterior faรงade of the podium gives a luxurious effect and is an ideal material because of durability i.e., long life and resistance to weather

The entrance lobby is also clad with marble and backlit onyx to exude the luxury it stands for.

The entire façade of the building is soft lit, mainly highlighting the common areas like the podium and compound wall so as to maintain privacy for

the residents.

True to its name, the Greenfields residential complex reflects closeto-nature character with ample light, airy spaces, greenery and earthy colours. In the midst of Mumbaiâ&#x20AC;&#x2122;s high-rises, Greenfields proudly stands apart as a visual delight in the concrete jungle.
