Adaptive, Urban Façades Sustainable

A

ccording to the United Nations, more than one half of world population now lives in urban areas.

Urbanisation is increasing in all countries of the world. It is known that there is a clear link between urbanisation and environment. This is evident from the fact that cities have high demand for resources and have higher pollution levels compared to rural areas. So, it is important to ensure the new infrastructure, especially buildings are environmentally sustainable.

Buildings account for one-third of global energy use, and significantly high carbon emissions. Considering the fact that a large fraction of buildings is going to be built in the coming years globally, it becomes

10

imperative to follow sustainable building design strategies to minimise the environmental footprint. Buildings need to be designed in the right way from the concept stage to achieve high efficiency and minimal cost.

Air conditioning accounts for nearly half of the energy consumption in a typical office building. The building façade can contribute to anywhere between 20-50 per cent to the air conditioning energy consumption in a building. This means the building façade accounts for 10-25 per cent of the total building energy consumption and is one of the single biggest contributors. So, a careful design of building façade is necessary to ensure an efficient building.

Façade is the outer skin of the building that acts as a barrier between

WFM l March - April 2018

the interior and exterior. The primary purpose of the façade is to protect the occupants from outdoor weather conditions, and provide a comfortable living or working space. There are a few points the design team needs to discuss with all stakeholders and be clear about before finalising the façade of a building. All stakeholders of the building need to understand that design of the façade cannot be an independent activity. It has to be a holistic design approach where the impact of different design elements of the building (including façade) is studied in relation to each other and on the comfort of occupants and total building energy consumption. Most importantly, the façade needs to adapt to the local climatic conditions to effectively serve its purpose.

Green Talk 1. Form Vs Function It is often a designer’s dream to have a building that has a unique language/character. It is incorrect to conceive the form of the building/ building façade without studying the functional aspects.

While requirements like heating or cooling depend on the climate of the location, requirements like natural light, views, etc. are dependent on the functionality of the spaces inside the building. The designer may come up with a fully glazed façade, which may be good for cold climates that need to welcome the sun inside the building for most of the year, but may be disastrous for tropical climates that require cooling for most of the year. The functionality of the building with respect to occupants should be more important than the design from outside. There may not be much sense in having a fully glazed building that may look appealing and “futuristic” from outside, but people inside experience problems of glare and thermal discomfort. So, while designing a building façade, though it is important to have an aesthetic appeal on the exterior, what matters most is the comfort of the people living or working inside. So, the priority in design should always be function over form. Creative

designers can find several ways to balance function and form by having appropriate orientation, window-wall ratio, shading, insulation and right material selection.

2. Ease of Installation Vs Essentials In the building industry globally, any decision on approval of projects takes a long time, at the leisure of the management, but once the approval is given, there is an unfathomable hurry to get the project completed.

This actually results in compromising on essential aspects like safety, energy efficiency, poor detailing of several building elements, cutting corners to make installation easier and quicker, etc. Installation of façade is a one-time process for a building, and if done in the right way ensures safety and sustainability of the façade for the life of the building.

Safety should be of prime importance while designing a façade in terms of structural safety as well as fire safety.

Structural safety can be ensured through right design calculations and specifying the right material for the job. Fire safety requires right detailing to ensure there is no possibility of a fire hazard, appropriate use of fire retardant material and isolation of any combustible material, more so in case of high-rise buildings.

An example to learn from is the unfortunate fire in a London building

a few months ago. It was shocking to know that a fire that presumably started in a fourth floor kitchen could burn almost the entire façade on all sides of the 24-storey building. The façade material was suspected as one of the main causes for fire to spread and some investigations pointed to cavities in the façade system leading to the fire spreading quickly. So, right detailing and selection of material is essential for ensuring fire safety.

Another essential aspect – sustainability needs to be considered to ensure the building façade is efficient and contributes to low operating costs for the lifetime of the building. Insulating the walls and roof, high performance glass and shading for windows should be integrated with the regular façade construction so as to maintain ease of construction, and at the same time reduce the requirement for lighting and air conditioning during operation of the building. In high-rise buildings where introduction of exterior shading elements might be a challenge, one option is to consider a double façade that can act as a ventilated façade as well as achieve the effect of shading.

All it needs is a small effort from the project team to ensure safety and sustainability of the building façade.

So, the priority in design should always be essential over ease of installation.

3. Cost Vs Benefit Cost always plays a critical role in decision making for any building project. Introduction of any element like insulation, shading, etc. on the façade is treated as an additional cost that requires justification.

But if the cost details are studied holistically for the entire project rather than façade alone, then in most of the cases, one would end up with no additional cost for the overall project.

The benefit of adding insulation and shading on the façade is actually seen in the air conditioning capacity reduction, which also leads to reduced electricity demand and lower capacity electrical systems. In some cases, an efficient façade reduces the cost of air conditioning and electrical systems to an extent that there is an effective reduction in the overall project cost.

Case Study - Infosys Buildings The office buildings of Infosys over the last nine years have followed a holistic design approach and have set benchmarks for energy efficiency.

Prior to 2008, the energy performance index (EPI) of Infosys buildings used to be about 200 kWh/sq m per annum. Through a focused approach to energy efficiency, the new designs from 2008 onwards included a very efficient façade, innovative lighting and air conditioning design and automation, as a result of which the EPI has been reduced to 75 kWh/sq m per annum.

The new buildings

of Infosys are 60 per cent more efficient compared to older designs with no extra capital cost.

Efficient façade was the single biggest contributor to achieving high performance buildings. Infosys moved away from glass buildings to rightly designed buildings with optimum window-wall ratio that ensures minimum heat gain but adequate natural light. The data given in table-1 shows the reduction in critical operational parameters as well as those affecting capital cost.

53 per cent lesser air-conditioning capacity meant a huge reduction in capital cost of air conditioning as well as electrical equipment.

Infosys buildings demonstrate clearly the advantages of adaptive sustainable facades on overall building performance and capital costs. It is wise for the project teams to weigh the benefits and make a smart choice of façade adapting to each situation, so that future urbanisation is less harmful to the environment.

Façade Lighting

Lighting the Façade: New Age Real Estate

Façade lighting - Police Commissionerate, Jaipur

Façades Vis-à-Vis Architecture The fascia of building - be it modern or historic - is one of the most essential aspects of architectural design, governing factors from the ingrained identity of a building to the designer’s first impression on both the inhabitants and visitors. In the modern architectural world, façades have become an important showcase of technology, branding, identity for owners, designers and building

14

developers alike. New materials, advanced detailing and versatile possibilities are adding fuel to the fire in the dynamic world of BIM driven buildings. Also, the competition to design a better and unique façade is also building up not only in India, but globally as well. Taller, grander and complicated the façade is, the more popular the building becomes.

However, it is important to note that

WFM l March - April 2018

the night visibility of the building façade is also becoming important nowadays. Such efforts enhance the image of the city which has a rippling effect on the overall lifestyle and visibility of the city. Façade lighting thus has an important role in building a world-class city. The benefit of façade lighting can be seen in all types of buildings – whether old or new.

Façade Lighting Light and Architecture Light and architecture are inseparable virtues of built and unbuilt spaces.

Light is of decisive importance in experiencing architecture, as one cannot experience form without lighting. Many great architects have underlined this intertwined relationship through theories and real projects including Le Corbusier, Louis Kahn, B V Doshi, Raj Rewal, Charles Correa and many more. Much has been published in this regard and cannot be emphasised more.

Façade Lighting – Introduction & Need With unprecedented urbanisation and most of the global GDP growth taking place in the world’s top cities, more and more municipalities are investing in lighting to make their cities more livable by creating vibrant urban activity at night. New lighting on building structures can ● create unforgettable visual experiences ● increase pride of residents ● attract tourists and ● drive commerce

Alliance Building in Callao Square Edificio, Spain

Around the world, many large structures are being impressively lit in creative and artistic ways to stand out, building unique and strong identities for them. Making these structures dynamic help them become part of our lives and can define a location, a city or a brand. It can also influence how we respond to a place and our emotional connection to it. And now with the flexibility of remote programming, this lighting can change almost instantaneously, keeping a brand fresh or a destination

compelling. This can help attract tourism and drive commerce.

The safer and welcoming a city feels, the more citizens and visitors will enjoy it. Lighting creates exciting spaces, making people spend more time there, eating, drinking and taking in the sights. Using beautiful, energy-efficient lighting to create vibrant social spaces can also have a dramatic effect on a city’s reputation. It enhances tourism and nightlife, generating valuable income for hotels, restaurants, bars and shops. Hence the city becomes a more attractive destination for people and businesses. An investment in lighting that practically pays for itself.

Over the last twenty years, architectural lighting has become more than simply a means of ensuring security and visibility. It is regarded as an essential component of city planning and development and an excellent way to reveal the heritage and identity of a city, whatever the size. Architectural lighting can give a city a nighttime beauty that matches its daytime image. By altering the urban landscape, the relationship between the citizens and their city can be redefined and their living environment can be enhanced.

Façade Lighting Design Considerations Lighting effects range from enhancing and highlighting façade elements, to totally transforming the face of a building. Multiple factors affect lighting design and this article attempts to bring the same perspective to designers who wish to attempt the same.

Façade lighting design involves two key approaches, not necessarily in that order a. What to Light? b. How to Light? a. What to Light?

It is not necessary to light the whole façade, but to light the most significant areas of the façade, i.e., where the most impact can be created. This is determined by finding out the major viewpoints of the façade from the context – both macro and micro. It is recommended to review the areas of the façade that have the least view blockage due to trees, neighbouring buildings, etc. and maximum impact to viewers. These viewers can be vehicles waiting at an adjacent traffic light, or people waiting at the entrance

and exit of a building, immediate public plazas, or if for high-rises, the people in a larger context. Having water bodies in the periphery can enhance the lighting effect by reflecting it.

The peripheral illumination around a building can cause the lighting effect to diminish. Hence it is advised to choose the darker parts of the façade, for e.g. the upper parts and move away from prevalent and ambient street lighting.

Also lighting fixtures and effects should also be positioned in such a way that they do not cause glare to viewers.

The design style of the façade can determine what elements (like columns, windows, spires, sunshades, etc.) to illuminate. For example, a building having a specific pattern of solidity and void, through a colonnade in the façade, the columns can be highlighted to highlight this pattern at night. b. How to Light?

Any design activity involves a triggering ‘intent’ of design, or the story behind the design intervention.

It is important to adjudge the intent

of façade lighting. This concept then governs every design decision and answers questions like what mood to create, what style of lighting to choose, etc.

Identify, it should be based on the larger context for which the structure is famous for, and what kind of spaces and people it caters to. Also determine how your building can add to this image of the city, as a landmark and a point of attraction.

The typology of the building is a major factor for intent of the design.

A retail space can be activated by an extravagant and celebrative style of lighting, an office tower can become an icon and a landmark in the city through dynamic and far-reaching lighting style, while a hospitality building can be made more welcoming through lighting.

The original building design and concept can be upheld through lighting design as it enhances elements in a façade. It is recommended to carefully identify if the façade has a unique style, rhythms, patterns, symmetry, scale, balance, contrast and mood of the space which can be highlighted through lighting.

Design Observations The following are the general considerations and precautions one must keep in mind while designing the lighting for a building façade. On the basis of the specific conditions of each lighting project, some of these considerations can gain more importance while others can be neglected.

WFM l March - April 2018

● Height of the building/elements – This represents the actual height of the lit surface. ● Position of light source – To be practically located, owing to vandalism and maintenance possibility. Also proximity to people as well camouflaging techniques are important pointers here.

Façade Lighting ● Width of the building/elements – This has impact on number of light sources and beam angles to be chosen. ● Façade material-texture, reflectance, colour – This is a strong clue to choose the overall lighting strategy apart from the scale of the structure. ● Peripheral light in immediate context – It is important to take

note of existing ambient lighting in the surroundings. ● Weight of the light fixture ● Avoid light pollution - Façade should not be excessively lit. Carefully choose what elements to be lit. Need to design façade lighting for the most viewed/most prominent sections of façade with least peripheral light.

AR. ASHISH BaHaL

Façade lighting of County Hall, London

About the Author:

Lighting Techniques Prevalent lighting techniques of today include ● Direct View – The fixtures are placed on the façade to be seen. E.g. Media façade – recommended for glazed façades. ● Grazing – The fixtures are placed very close to the façade with high illumination at the base and receding with the height – highly recommended for textured façades.

● Washing – The fixtures are placed little away from the façade uniformly washing the façade – recommended for specular finished and flat façades. ● Accentuating – The fixtures are placed very close to create dramatic effects, especially for columns, openings, etc. ● Flooding – The fixtures are placed far from the façade with uniform illumination of the façade. Hence termed floodlighting.

Conclusion Façade lighting is not rocket science, but needs a focused and sensitive approach towards the intent. A little bit of practice and experimentation can bear great results and generate high return on investments in this rare category of lighting especially in Indian context.

Importance of Performance

Testing for Well-Designed Building Façade

A

s more and more Indians travel around the world they are exposed to the cutting edge technology used in modern buildings which exist in different countries and they notice the use of latest to make them unique and iconic.

Some of these appear to defy the laws of gravity and science. Architects who have been involved in creating and execution of these unique projects have not just focused on the design aspects of the building but have gone through extraordinary lengths to ensure that the performance of the products used in these projects are tested thoroughly for safety and performance during its lifetime.

India is now fast catching up with the other developed nations in all the other aspects of development and is leapfrogging into the future with rapid growth of its cities and towns. The pressure to build taller and more efficient structures and make the maximum use of available space

20

WFM l March - April 2018

exists in almost all Indian tier 1 cities. Therefore with the construction of such tall structures comes the need to ensure that every component that goes into the structure is tested thoroughly to ensure that it performs to the desired specification. The inherent difficulty in replacing damaged or underperforming product once it is installed in high rise buildings is quite obvious as it involves a lot of expenditure.

Sometimes, it is virtually impossible to carry out any repairs due to non-availability of access and the residents of the building will have to live with the problem for the rest of the lifetime of that building.

When it comes to facades of buildings, the consultant or architect responsible for the project needs to ensure that the façade is just not aesthetically pleasing but also structurally safe and energy efficient. The design should incorporate adequate features to ensure easy accessibility to the façade for regular maintenance and repairs in future.

Façade Safety Provisions also have to be made to comply with the regulations laid down by the fire department for emergency evacuation in the event of a fire.

When all these factors are considered before the final façade design is approved, it is important that all the calculations for structural

Mock up sample curtain wall on which the tests are done

stability, energy efficiency and water penetration have been done based on certain realistic assumptions.

Since the possibility to rectify or replace the façade once it is installed is near impossible, every care should be taken to test the mock up sample for extreme conditions and make the

necessary corrections even before they are installed to ensure that its performance matches the design criteria.

The role of independent performance and fire testing labs has gained importance in the last few years to do just that i.e. simulating weather conditions as per the design criteria and putting the mock up sample through a series of tried and tested procedures to validate the theoretical assumptions used during design. Once a mock up sample is tested to the specified conditions and certified, the design, quality of fabrication and installation methods can be safely assumed to deliver the value it is expected to provide.

After the testing at the laboratory, the approval is given to façade contractor to begin installation of the façade at site. To ensure that the quality of fabrication and installation continues to be in line with the approved process onsite water testing as per AAMA501.2 is recommended.

A third party independent lab would conduct onsite water testing at random locations on the façade, as decided by the consultant and the entire process of testing is recorded on video for future reference. Any failure in the water penetration test at site would result in the work executed until then being reviewed and retested to ensure that there are no surprises after the project is handed over to the owner after completion.

Many testing specifications have been designed to test the facades over the last few decades.

ASTM, AAMA and ASNZ are few of the standards consultants use to ensure that the facades perform to the required specifications. All the above mentioned standards are well recognised across the world and ensure that the final quality of the façade is matching its potential.

Given below is a typical specification for a façade which covers all kinds of performances expected of a well designed façade.

To be applied 3 times both ways in cycles d. No distortion or visible damage shall occur 8. Repeat static water penetration test to ASTM E331 (As outline above) 9. Structural safety test: Uniform structural load test at proof load per ASTM E330: a. Positive pressure: 75 percent of design load b. Positive pressure: 150 percent of design load c. Negative pressure: 75 percent of design load d. Negative pressure: 150 percent of design load e. All pressure to be held for 10 seconds 10. A BMU tie back shall be tested in all directions (for value of loads to be applied, refer to the relevant section of this specification). A static pressure of 0.5 Kpa shall be applied for the duration of the testing.

24

The tie back shall not fail, exhibit permanent distortion or interfere with the performance of the curtain wall and related seals.

11. Degradation testing: If deemed necessary by project architect or facade consultant, on completion of the structural testing, a further series of water penetration test shall be undertaken with portions of various gaskets and sealant beads removed on each test assembly. The purpose of such testing is it to simulate the effects of degradation and failure of such seals and is carried out for information only.

Once the process of testing is completed all the parties involved in the design and execution of a façade would get the satisfaction of having completed a project which is safe and energy efficient.

A façade forms a very vital role in giving a building character and any failure in the performance of this vital element will result in enormous pain and loss to the owners and residents of the project.

So in conclusion all parties involved need to recognise the importance of performance testing and realise that the cost incurred in testing is paid back many times over by the value the developer will derive from a safe and energy efficient façade.

21st Century Software Solutions for Door, Window & Façade Industry

S

oftware has changed the way we do business in the 21st century. These amazing programming tools can manage range of business processes right from inquiry stage to site installations.

Fenestration companies in India can now benefit from these variety of software available to enhance its business.

Fenestration industry software’s can be categorised in two types. To begin with, let’s talk about software which specifically focuses on designing and fabrication of doors, windows and façades; here the profile and the hardware database plays a key role.

Then we have ‘Enterprise Resource Planning software’ (also known as ERP systems) which can manage an array of your entire business. ERP

systems bring all business processes and data on one platform. This not only increases efficiency but provides real time visibility for your fenestration business.

Design and Fabrication Software Design and fabrication software are equipped with databases of numerous well-known architectural profile system suppliers in aluminium and uPVC. These easy-to-understand programmes make it possible for users to design door, window and façade in software with choice of profiles, hardware and accessories. The software leads you through the entire design process of fabrication step by step, so you do not miss out on any component. Fenestration companies should consider software’s core features and functionality against their

business requirements. 21st century design and fabrication software comes with essential features such as ‘material optimisation’ to minimise wastage, project cost analysis, project labour report, bill of quantity, supplier purchase orders, quotation, work order, delivery note and invoice.

Some intricate features of design and fabrication software include calculation of U values for energy saving and auto generation of structural analysis report. On the production front, software automatically calculates all the necessary data and transmits machine readable files to your milling and notch machining centres.

Most interesting feature in the software is the CAD interface. Most prominent fenestration software comes with an internal CAD interface

Tech Talk which is simple and user-friendly. An easy to understand arrangement of all relevant functions provide you with a ready to use CAD output. For your architects delight, these CAD outputs of door, window and façade show you all the profile elements with hardware as an overall cross-section.

Design and fabrication software can prove best fit for SME businesses who want to focus on areas such as design and fabrication. Since these software emphasis on engineering aspects of fenestration business, they commonly do not come with modules like customer resource management, stock management, job tracking and procurement.

Doors, Windows & Façade ERP Enterprise Resource Planning systems, commonly known as ERP systems, are a perfect fit for owners who want complete control over their

fenestration business. A bird’s eye view of the entire company which allows managers to precisely monitor and plan business activities much efficiently by using big data to generate various Business Intelligence (BI) reports, and precisely forecasting business events which help managers make faster and timely decisions.

In India, fenestrations businesses have invested heavily on enterprise software solutions to monitor and grow their business. The year 2017 saw some prominent fenestration companies investing millions on development and implementation of these ERP systems. A single enterprise software which typically integrates all areas of your business including sales and marketing, customer resource management, project planning, manufacturing, quality assurance, dispatch and site management.

Fenestration ERP systems will typically use a combination of different modules to manage activities and tasks. Most common modules include:1. Customer resource management 2. Document management system 3. Project costing and management 4. Stock and procurement 5. Production planning and tracking 6. Sub-contract management 7. Delivery and transport 8. Site installation 9. After sales In last couple of years, we have seen CEOs taking keen interest in Barcode and RFID Technology. Barcode based tracking is now commonly used in India to maintain stock and inventory.

More recently we have seen RFID technology entering the industry mainly to track crucial production stages. Production tracking is core function of the ERP system; a module which allows stakeholders to precisely monitor production of doors, windows and façade. Systems that allow production manager to track a “single product” by creating time stamps of its every production event. A bird’s eye view of software dashboard, can allow managers, and owners to monitor every stage of production live.

Automation is the key to ERP system’s success. A software which can increase visibility, grant total business control, increase timely coordination, send advance warnings and alerts, eliminate business redundancies, increase profits, and gain a significant competitive edge on the market place.

and implementation can be a complicated and challenging, as every company is different, and so are their business processes. Over the years, we have seen significant rise in software acquisition. To invest in a right software is an important decision, but most companies commonly ignore the implication of implementation and training of software. While products based software require less time on implementation, ERP systems need at least a month for completion of this stage. Both implementation and training are crucial stages which cannot be ignored; a buyer needs to consider cost of implementation and training which will easily add about 2030 per cent of software purchase cost.

In recent years, most software companies offer additional implementation and training packages whether you are buying bespoke solution or a ready-to-use product

Although these packages would add a cost to your software budget, it is of vital importance to implement the software in a defined manner into your business. Software training is another crucial stage where minimal emphasis is given. Training is strongly recommended for staff and stakeholders. A software is worthless if its users do not use it correctly, or to its maximum capability.

Latest Technology Trends More recently we have seen a steady rise of bespoke or tailormade fenestration software. Whilst software development, we have seen rise in demand of modules like “LIVE alerts” for customers and business owners through SMS and

email. Another interesting module we have seen is a dedicated “company messenger” integrated in the ERP for inter-departmental communication; here chats can be linked to LIVE JOBS for internal record. Demand for customised dashboard for each ERP users with their daily tasks, reminders and favourites charts and graphs, are common requests. Recently we have seen more developments on site management areas where business wants software users to measure, snag, track, and report through an “ERP MOBILE APP” from remote site locations.

“Human ability to harness data in software systems is now empowering fenestration companies in India to take actionable decisions and offers spurs to boost sales and fulfil customer demands.”

Facade Perimeter Firestop System

Need of the Hour

restricting its faster spread without relying solely on fire department.

Except very few, many of our states do not even recognise firestop systems under their ‘No Objection Certificate’ check parameters. Recent fires in Dubai and the Grenfell Tower fire accident in London raised back the question of façade fire protection again. Luckily for us, the National Building Code of India had also been revised after almost 11 years and this time it also brings forward some good points regarding facade fire safety by restricting its growth at the perimeter void itself.

Fire at First Interstate Bank which started on 12th floor and spread to the 16th floor via unprotected void at the edge of the slab.

ndia is a developing country and also the second most populous country in the world. Our cities are growing taller and taller and the industry is demanding energy efficient and clean looking systems.

Traditional construction in India has always been a brick and mortar type of construction. But since last decade, we are seeing a huge increase in highrise structures with facade systems.

Every technology and material has its benefits and associated risks. Facade related fire safety risks are one such risk, which are still at premature discussion level and needs a lot more attention.

In a practical scenario, we often discuss as to how to respond when a fire occurs. What we often ignore is that how to get such fires contained under one compartment itself and

WFM l March - April 2018

Little History In 1988, First Interstate Bank Building in Los Angeles caught fire on the 12th floor extending to the 16th floor in a 62-storey building.

"The lack of firestopping between the floor slabs and the skin permitted the fire to spread from floor to floor through this space. Fire was observed spreading through this area even before the glass and mullions failed,” said the Chapman, Elmer F. “HighRise: An Analysis,” Fire Engineering”, August 1988 report.

It was identified as per the investigation that the fire was originated on the 12th floor and spread to upper floors via lift shaft and the unprotected opening at the edge of the floor slab and facade system.

India has also suffered its share of losses from such high-rise fires.

Mantralaya fire and Lotus Business Tower fire in Mumbai are a few examples of such losses, we had seen.

Fire Safety

Fire at Lotus Business Tower, Andheri, Mumbai

There are many examples but through such losses, it was observed how critical it is to address the fire risks associated with facades. There are multiple ways by which fire can grow from the façade and slab assembly point.

Each of these paths shall be addressed by evaluating it separately.

In India, unfortunately we do not have a specific test standard to evaluate such systems, but internationally there are some standard available from NFPA codes which establishes different requirements for each potential path and address the means to protect the paths or to prevent the spread of fire based on each separate one. During the recent revision of National Building Code of India 2016, perimeter fire stopping was also recommended under clause 3.4.10.2.

hidden from view after construction, and once installed, due to their location, such construction gaps are never inspected or reevaluated unless some major retrofitting comes by. But when such openings are left unprotected, they provide the perfect space for the fire and smoke to spread upwards. Such a spread of fire when reaches to more than one floor also

Why is this so important? To understand this, we have to go back to the basics.

As we all know that curtain wall structure is a multi-storey structure where exterior walls are not part of the load bearing structure. As the common construction methodology, the floor slabs are supported by interior beams and columns. And, we mostly encounter a perimeter void typically of the range from two to eight inches between each floor slab and the exterior curtain wall.

Perimeter voids are generally

Multiple paths that a fire can take at the edge of the slab opening

weakens the sprinkler system by overtaxing its design criterion and makes it almost impossible to control with available systems. Hence, these openings must be sealed to prevent spread of flames, smoke and toxic gases in case of fire breakout.

As with all passive fire protection systems, the intent of sealing the edge of the slab opening with fire and smoke resistant system is to confine fire to its room of origin and prevent its propagation through the floor, ceiling, or walls. With ineffective curtain wall and perimeter void fire protection, fire can spread through the space between floors and walls, through the window head transom and the cavity of the curtain wall, or through broken glass or melted aluminium spandrel panels.

The mechanism of fire spread in a curtain wall is primarily through chimney effect, leapfrog effect and poke through effect.

Chimney Effect: Chimney effect is attributed to the spread of fire upward through the available openings between the floor slab edge and the curtain wall.

Leapfrog Effect: Leapfrog effect is seen in mid- to high-rise building fires where flames blasting out through perimeter windows leaps through the windows above and continue to spread vertically by following similar effect every floor.

Poke Through Effect: Poke through effect is where flame and hot gasses penetrate through openings in firerated walls and floor/ceilings ignite combustibles on the other side.

Perimeter fire barrier systems are used to resist the interior propagation of fire through the gap between floor and exterior wall for a period equal to the floor’s fire-resistance rating. Additionally, all the building components are subject to various movements such as thermal, wind or seismic. Hence, a building’s perimeter fire barrier system should accommodate various movements,

such as those induced by thermal differentials, seismicity and wind loads.

Curtain wall design became common in the west in around 40 years ago, but in India it has started to gain huge momentum hardly a decade ago. Inherently, this comes along with multiple risks as well, such as fire and smoke. In India, as such, for now there is no test standard to test and evaluate such system as one to really identify the fire and smoke performance of such systems.

However, there is a standard called ASTM 2307 "Fire resistance of perimeter fire barriers using intermediate-scale multi-storey test apparatus" which came in existence

34

WFM  l  March - April 2018

Fire Safety in 2004 and got widely accepted to test the perimeter firestop systems for facade.

The ISMA test simulates fire exposure in a high-rise structure where, as the fire intensifies and positive pressure builds, a fireinduced window breaks occurs, allowing oxygen to feed the flames.

The method is meant to simulate a fire in a post-flashover condition in a compartment venting to the exterior.

The provisions of ASTM E2307 are intended to restrict the interior vertical passage of flame and hot gases from one floor to another at the location where the floor intersects the exterior wall assembly. Its use is mandated by US building codes, thereby requiring the protection of openings between a floor and an exterior wall assembly to provide the same fire performance as that required for the floor.

Test Sequence: 1. Cycling Test: The test method requires joint systems with movement capabilities to be cycled through the intended range of movement prior to the fire test. The movement cycling is intended to demonstrate the compatibility between the individual components of the joint system and the supporting construction. Joint systems are required to be cycled through the intended movement range 500 or 100 complete movement cycles at a minimum rate of 1, 10 or 30 cycles per minute prior to the fire test.

2. Fire Test: Throughout the fire test, observations are made about the fire and hot gases on the unexposed side of the perimeter fire barrier or any adjacent supporting construction.

The above certificate is from a third-party testing laboratory – UL which highlights the curtain wall system which got successfully tested as per the ASTM E2307 test and given a rating of 2 hours.

Fire Safety After successful completion of the above mentioned tests, following ratings are provided to the entire perimeter fire barrier system per ASTM E2307 Test: • “F”-rating, in hours (resistance to fire spread) • “T”-rating, in hours (temperature on non-fire side) UL provides two additional ratings using same test apparatus • “integrity rating” & “insulation rating” Test result: It is very important to review the test certificate details and verify each detail mentioned in a test certificate and the limitations of the system passed.

Conclusion: In Indian scenario

where

we

have traffic issues coupled with longer fire response time, it becomes even more important for all stakeholders starting from building owners, architects, façade consultants, contractors and inspectors to take a justified approach by using only tested systems for protecting the perimeter fire openings.

Avoiding or compromising the edge of the slab opening with no or untested system means compromising with the safety of people. Perimeter fire barriers are one of the required systems from the National Building Code of India and it is an effective fire and smoke resistance compartmentation methodology.

These technologies are developed and being further innovated to save lives and protect property damage.

As per your view, how important is the role of right cladding in achieving system performance, optimum acoustic and thermal insulation as well as in achieving the desired aesthetics?

As the product serves at the outdoor and replaces many traditional ways of protecting exteriors, it must outperform the biggest challenge of exterior surfaces, which is achieving maximum thermal insulation with the right balance of aesthetics.

Merino Armour Wall Cladding is a star performer when it comes to this parameter as it has to its credit a special energy saving system, through which air can ventilate between the subsets during installation, which aids absorption of excessive heat, moisture, resulting in an average 20 percent reduction in energy consumption by retaining indoor room temperature. Also, the insulation remains corrosion free.

As far as aesthetics are concerned, there is an eclectic range of diverse designs and colours to choose from:

be it woodgrain, patterns or solids ranges and all are weather, pollution, corrosion resistant and termite free.

How well aware do you think the decision makers are in general about the availability of the cladding products, its functionality, and categories? And how do they gauge the effectivity of the same?

As far as B2B decision makers are concerned, they are well aware of the cladding products available in the industry, and we are constantly deriving new ways to showcase the USP's of our products. Our successful EWC project sites across India speak aloud for itself in the industry to relevant decision makers like the architect and interior designer fraternity.

The end user, who is the extended client of our B2B influencers, is fairly aware of the EWC functionality. Due to newly emerging trends of exteriors, this product category needs to be explained to the end customer vis-àvis other traditional products.

Moreover, there is a constant challenge in positioning EWC as a better replacement to the traditional

WFM l March - April 2018

ways of doing exteriors which could be stone, paint or tiles. The cladding offers many advantages as it is durable, tough and aesthetic in terms of protection against all weathers, UV rays, climatic shock, corrosions, termites, moisture, impact, abrasions, graffiti; it is also easy and quick to install and has energy-saving techniques. Gradually, EWC is carving a niche for itself amongst the B2C decision makers too.

What is the emphasis laid on R&D, especially for the Indian market?

Merino lays special emphasis on R&D because the introduction of new products is the key benchmark for the group. We are continuously working with international partners to bring in the most modern technologies and products in the market. All our manufacturing facilities have dedicated labs focused on development through sustained improvement and new innovation.

What do you foresee are the main challenges faced by the wooden laminate industry?

The industry needs to get more

Industry Speaks organised as the end consumer is still not aware of the benefits of the laminate which is way beyond aesthetics. The industry collaboratively has to work towards educating the end customer on empathising how the product is more economical and environmentalfriendly.

The group has focused on ensuring on-time and full deliveries to the customer as per their order requirement for which special initiatives to improve the supply chain has been made. We are also working with our channel partners in opening

an organised gallery and exclusive display centres in 2018. Another strategy taken by the company is to expand the channel and to work with the carpenters.

What keeps the company ahead of its competitors in terms of services offered?

Our organised and well-planned methodology of working, stringent quality certifications, more than five decades of association with the channel network and design fraternity, our outstanding product quality and services and not to forget our extensive design range, all these features keep us ahead and leading players in the industry.

We offer an extensive array of surface solutions under one roof and

Cladding serves many purposes, including creating a controlled internal environment, protecting the building from external conditions, preventing the transmission of sound, for providing thermal insulation and improving appearance of buildings, among other things, says Amit Shah, Managing Director, Classic Marble Company.

Cladding maintains privacy and security of exteriors, provides access to ventilation and hygienic environment and prevent the spread of fire. Basically, its properties like termite resistance, waterproofing nature, environmental friendliness, and their wide range of colours & designs make cladding a trend, notes Rachhpal Kanwar, General Manager – Exterior Cladding and Cubicles, Stylam Industries.

The main functions of any cladding are to provide enclosed area which will provide protection from all-weather condition like rains, wind, cyclone; also the safety of inhabitants is major concern while designing a cladding system. According to Upendra Walinjkar, Director, Aluvision Façade Solutions Pvt Ltd., all these can only be achieved with very good structural and system design.

Alhad Patil, Technical Director, Diamond Metal Screens, observes that exterior cladding, especially perforated metal façades, plays an important role

on the structural aspects of the building.

Being generally light weight in nature – due to perforations, they add minimal weight/sq m to the building, while adding a host of advantages such as ventilation, sun screening and more importantly dissipating heat absorbed structurally through the aluminium second skin.

According to Akash Saini, Director, Notion Flooring, cladding not only provides protection but also enhances the architectural concept and appearance of the building. Its impermeable and porous material helps to absorb water during rainfall and completely keep out the rain infiltration and keep buildings secure and safe.

Purpose of cladding: • Create a controlled centralised environment • Protect the architecture from alien conditions • Prevent the transmission of sound • Provide thermal insulation • Create an external façade • Prevent the spread of fire • Generate an 'airtight' architecture envelope for building • Provide openings for access, lights and ventilation (Source: Century Ply)

of

Cladding, even though essentially the nonstructural secondary surface attached to the primary structural surface of the building, has a fitting effect structurally on the building, points out Prof. Charanjit S Shah, Founding Principal, Creative Group. Though it is merged with the primary face of the structure, it does not contribute to the stability on the whole.

Regardless, it does play a structural role transferring wind loads, impact loads and its own weight back to the structure which implies that ample amount of strength is required both within the cladding system and its joineries for the primary face to ensure that it does not crumble under wind load pressures. Walinjkar too agrees with this statement.

According to Rohan Keswani, Director, Aluplex India Pvt Ltd, curtainwalls and cladding materials are designed and engineered to withstand wind loads based on the topography and geometry of the building, the deadloads of the curtainwall, the live loads imposed, seismic loads and thermal loads, whilst also accounting for loads imposed on the cladding due to building movements such as column shortening and creep movement. The cladding is designed to limit the deflections of the cladding framework and infill panels within serviceability limits, as desired. More importantly, design and engineering checks are carried out to ensure that the

stresses within the façade elements are limited to the yield stress to ensure that there is no permanent deformation of the materials. Further, the framing members of the cladding are designed, engineered and checked to ensure that there is no buckling caused by the compression loads imposed in the axial direction (Euler Buckling), as well as, the compression loads imposed due to bending (by lateral torsional bending).

In explicit, wind causes positive and negative pressure on the surface of buildings and cladding should have ample strength and stiffness to resist this load, each in terms of the types of cladding chosen and its connections back to the structure, explains Rajendra Shah, General Manager - New Age Products, Century Ply. Cladding can help to reduce mechanical and electrical energy needs, and so enhance electricity efficiency and lower the running costs, he adds.

designer, types & properties of the product, the loading factors at desired location and elevation angles, adds Shabbir Kanchwala, Senior Vice President, K Raheja Corp.

In today’s context, choosing the right cladding system is essential to bringing in the environmental impact of the building down in a future context as façade construction accounts for almost 35 per cent of the building costs, adds Ar. Gurpreet Shah, Principal Architect, Creative Group. A few other factors that might be essential to the selection of materials for the cladding system should be – usage type of the building, internal and external conditions, durability, local context, planning requirements, accessibility and buildability, appearance, availability, budget, maintenance requirements as well as the structural requirements.

According to Devesh Kumar, Sr. Manager – GICS & Technical Support, Aludecor Lamination Pvt. Ltd., in addition to the above points, the key factors for selecting the material for cladding are its ability to withstand wind load and fire ratings of the product.

Factors like building height, seismic conditions and required product size too decide the type of cladding, adds Julie Etavard, Business Development Manager (in charge of India market), Terreal.

Consideration of wind factor is important for selecting the thickness of the cladding, says Patil. Open areas decides the ventilation factor. The structural framing design of the panel is imperative for withstanding static and other dynamic structural loads. The material grade and coating decides its life span, preventing corrosion. According to Patil, the best choices are aluminium (marine grade – 5xxx series) considering saline environment, and Stainless steel 304 grade, though they are expensive but long lasting.

According to Keswani, the key factors to be considered while designing and selecting materials for cladding are structural performance, corrosion resistance, water tightness, air permeability, thermal resistance (by conduction/convection/ radiation), aesthetic intent and artistic finish, and reduction in carbon footprint.

Cover Story The Best Suited Products Considering Indian Climatic Conditions The Indian weather ranges from tropical in the south to temperate in the centre to Alpine climates in the North. So depending on the region, the choice in cladding materials could vary. Indian climatic conditions

require any façade materials to be of external grade that could withstand harsh conditions like hot and humid weather, and also highly durable on wet and dry climates, observes Rajan Govind. Market is flooded with traditional materials (brick, stones, wood) to the most innovative ones like Corian, Hi-Macs (an acrylic solid surface), Cor-Ten steel, etc., most common products used being wood,

metal, brick, vinyl, and laminates.

According to Keswani, the most suited cladding materials are those with low emissivity which reduces heat losses by radiation. He adds that in temperate climates, the primary heat transfer method is conduction and thus, the most suited cladding materials are those with low thermal conductivity, thus we use materials such as thermally broken aluminium profiles as well as double glazed units.

Considering Indian climatic conditions, explains Walinjkar, one need to choose cladding having following properties: • Resistance to corrosion: Materials shall be having high corrosion resistance like aluminium, steel and they should be properly treated with hot dip galvanizing and epoxy or PU paint.

• Cleaning and maintenance: We must know the cleaning cycle of the external building envelope while selecting cladding. (If cleaning cycles are not regular then we need to select material which will attract less dust and with minimum horizontal surfaces as architectural features, flush seal systems must be avoided, non-bleeding sealants need to be used for weather proofing of system, etc.)

Walinjkar suggests glass, aluminium solid sheet, aluminium composite panels (FR grade A2), natural stones, terracotta, pressure laminates (HPL), copper cladding, zinc cladding, fibre cement board cladding, Corian cladding, GFRC etc. as best suited cladding materials.

There are varieties of cladding materials/systems used these days.

It’s quite difficult to distinguish them from one another and numerous methods for installation too, says Rajendra Shah. The most suitable products are those which do not contain any hazardous substances like ash or asbestos. According to him, the best suited are fibre cement board (FCB) & fibre cement panels.

However, the all-weather cladding material popularly opted in the country are engineered marble and porcelain tiles, points out Amit Shah.

Saini chooses wooden cladding and waterproof aluminium cladding as the best suited products. Unlike the traditional cladding, they both can be easily fixed in the least amount of time, is exceptionally durable, lightweight and maintenance free, weather, moisture, and UV resistant as well as eco-friendly cladding.

These materials do not rot, warp, peel or fade and is even impervious to insects, adds Saini. It is also one of the pleasant materials that

neither gets too hot or nor too cold, maintaining the stability regardless of the external conditions. Further, stone and ceramic materials are also used in the cladding that provides earthy effect and also eco-friendly, helping the overall performance of the building.

Architects from Creative Group suggest terracotta panels as the most suitable cladding material since they are durable, resistant, requires minimal maintenance, thermally insulated and aesthetically providing another dimension to the building.

“Our highly intensive tropical climate calls for more measures towards ‘green cladding’ that will be able to add more years to the life of the building,” adds Charanjit Shah.

Julie Etavard too emphasises that terracotta cladding is compatible and excellent for Indian climate conditions.

Terracotta panels have low-thermal diffusivity; it contributes to a stable and comfortable indoor temperature during the day and night. Its ventilated system allows air to circulate throughout the panels (joints are not sealed) and cool down the whole facade. Also, they are fired over 1000 degrees celsius resulting to have fixed colours which will not fade over time and which are UV resistant. Pollution and acid rain are not damaging the products and they are maintenance free. Clay is a natural and inert material; meaning through its natural property, it keeps the heat received during the day and release it when it’s cooler during the night, helping to control the temperature inside, she adds.

To ensure the cladding accustoms itself to the geographical climate, products like Mangalore roofing tiles

or exterior stone finish that can be sourced from the local region and is abundantly available, are the best bet, suggests Kanchwala.

HPL (High Pressure Laminate) is the best for exterior cladding, says Kanwar, as it can be exposed to combined action of sunlight and atmospheric agents including rain, hail or wind deposits. These are not affected by thermal shocks and have the ability to withstand extreme climate changes. Further, it reduces the amount of water that is absorbed and provides protection against chemical or air pollution.

Role of Cladding in Controlling the Internal Environment The primary functions of cladding is to split the indoor environment of a building from the outside in such a way that the outdoor environment will not affect the indoors. It is also best for regulating the light penetration and controlling the radiation and conduction of heat from the sun, and prevents interiors from getting faded and dull. Additionally, sunshades and louvred panels allow for reflected light

Cover Story to enter the building that enhances the comfort, rather than direct sunlight.

Gurpreet Shah emphasises that the cladding is like a thermal layer to minimise heat gain/winter frost gain. If installed correctly with proper vapour cavities and ideally using climate favouring cladding materials with adequate insulation, the thermal mass can be rightly reduced, which in turn would make the internal environment of a structure very pleasant with little or no requirement for mechanical measures to regulate the temperatures inside.

Adding to this, Kanchwala points out that designs like filler slabs, double roof, cavity walls, composite walls, and shadings also help insulate buildings.

Contrary to the above comment of Gurpreet Shah, Rajan Govind observes that for Indian climatic conditions, insulations do not necessarily add significant benefits (except in very hot regions). Insulated cladding will benefit in reducing heat loads only for very hot climates, notes Govind. Furthermore, such cladding is majorly used on walls in front of shear wall or beam/column

locations. He also points out that any cladding system should be equipped with ventilated rain screen principle, so that the cladding system will have an extended life and lesser risk of corrosion and damage.

A façade which is ventilated and insulated can save up to 70 percent energy costs for heating or cooling the building. Cladding of a building ensures that the internal temperatures are maintained at ideal levels, reducing both the cost burden of HVAC and impact on the ecology, states Amit Shah. Another point mentioned by him is the protection from water permeation. Many parts of the country experience heavy rains and cladding serves as a coat which reduces the infiltration of water into the primary structure.

Acoustic Performance The acoustic performance of the cladding depends upon the substrate behind the cladding which may vary

as per the thickness of the wall and constructions, says Amit Shah. Devesh Kumar adds that insulated façade provides better sound absorption.

According to Rajendra Shah, the isolation of noise is excellently achieved with partitions which are airtight, large and resilient. The use of the resilient pad prevents transfer of sound originating inside the structure to outdoor, vertically through the cladding members, he adds.

Deviating from the above views on the acoustical properties, Gurpreet Shah points out that cladding necessarily does not provide adequate sound insulation with the exception of brick (a high mass, high thickness system).

The level of acoustic attenuation of the cladding material is decided based on the type of external and internal environment, with respect to the frequencies and amplitude of the ambient noise and sounds. Laminated double glazed units having a varying glass thickness, with acoustic PVB is the best choice for acoustics, states Keswani.

Cladding for Better Thermal Insulation and Effective Ventilation

Facades are designed with passive and active ventilation, such as double skinned facades that allow the warm air to rise, and exhausted from the void between the two skins, explains Keswani. Additionally, for high-rise buildings where windows cannot be opened due to high wind pressures, passive ventilators are the solution, which can be opened and closed.

Cover Story This allows for air circulation through the façade without the need to open the window.

Rear ventilated facade concept is quite popular and helps saving energy costs, while increasing the lifespan of building sustainability, spots Kanwar. He warns that poor design, detailing or installation may compromise cladding’s performance and can result in safety problems like cladding collapse or cladding panels pulling away from the structure.

One should pay particular attention towards control of air leakage, thermal movement, condensation, integrity and continuity of insulation, prevention of water penetration, maintenance, resilience, etc., while selecting or designing cladding to gain effective results in both thermal insulation and effective ventilation.

The cladding assembly can control the radiation and conduction of heat. Cladding is made from a low conductive material to stop localised condensation on interior surfaces.

It eliminates thermal bridges and controls/stabilises the desired degree of the conduction of heat into and out of the building.

Prof. Charanjit Shah too states that the integration of thermal insulation with the cladding system (the most common insulation materials being mineral wood and polystyrene), forms a closed insulation envelope which helps to eliminate thermal bridges.

the primary face and the cladding face is responsible for draining the heat and moisture from outside the building and prevent it from reaching the interiors which regulates thermal insulation to the greatest extent. Composite claddings having insulation with higher R-values (the measure of a material’s resistance to heat flow) can eliminate the need for bulk insulation between the frames in many climates. With effectively designed and efficiently mounted vapour cavities, condensation risk can be reduced or eliminated. Tensile fabric can alternatively be considered as a second cladding layer which provides a facade as well as shading to a structure.

With a selection of the better cladding system, says Walinjkar, we can achieve the desired value of thermal insulation. Wide range of products is available with low thermal conductivity (U-value). Widely used curtainwall systems can control the heat transfer from hot external ambient temperature 300C - 450C to an internal ambient temperature of 200C -240C by introducing the barrier of EPDM gaskets for better thermal insulation. Polyamide strips are used to cut the heat flow from either side and provides the best thermal values.

How to achieve desired U-value: ● With the use of Rock wool and mineral glass wool, we can achieve

very good thermal insulation on a spandrel area of facade by increasing overall system U-value. ● Curtainwall claddings support effective ventilation by use of openable vent. With advanced technology we can use active or passive ventilation in the facade, there are development in accessories for openable vent to maintain micro ventilation. Micro ventilation keeps the room well ventilated. ● The double skin facade provides great flexibility for the best combination of U-value and effective ventilation to remove hot air by natural or force ventilation.

The skins may be single or double kept 20cm - 100cm.

In the application, considering the cross-section of a Trombe wall, says Rajendra Shah, both the insulation values and transparency of the cladding material are of critical considerations, particularly in cooler climates where night time heat loss can offset the daytime heat gain.

Trombe walls rely on the combined action of thermal lag of the mass and insulation from the air gap. Unwanted convection is controlled with open able vents at the top and bottom of the wall. Additional insulation can also be gained in cooler climates through the use of double glazing (higher SHGC, lower R-value) or multi-celled polycarbonate (lower SHGC, higher R-value).

In India, one of the biggest energy consumption for buildings is its HVAC. Cladding structures ensure

Cover Story a significant reduction in the HVAC costs while reducing the carbon footprint. A marble clad façade can be made opaque with a set degree of opaqueness which is suited to a given environment. According to Amit Shah, this ensures that the building receives sufficient light while cutting off external noise and air pollution.

Fire Safety Strategies of Cladding Fire safety is the set of practices intended to reduce the destruction caused by fire. Local regulations for safety norms should be followed to achieve desired level of fire safety by use of appropriate materials.

Cladding materials play a key role in fire safety, hence it is important to choose the right materials. In lieu of the recent fires that have devastated many a buildings around the world (read. Grenfell Tower Fire) a shocking revelation has emerged, use of substandard cladding panels or an improper installation of the cladding system can undermine the safety of an entire building.

Fire safety of cladding need to be

addressed at the selection stage itself and any cladding material should comply with fire retardant characteristics and relevant international standards/local standards if exists.

Sometimes, what’s meant to protect the building from the external environmental discomfort might turn out to be the cause that facilitates fire, warns Ar. Gurpreet Shah. It, in turn dissolving other firefighting measures such as fire compartmentation and phased evacuation strategies. We can avoid the loathe of such hazards by ensuring that the cladding systems that have undergone proper fire safety tests and have the highest level of insulation magnitude. Another important point on the checklist is ensuring that the cladding systems are installed properly with proper joineries and fixing details.

Fire safety strategies of curtainwalling include the use of firestops and smoke seals to limit the spread of the fire and smoke from floor to floor, points out Keswani.

Fire strategies can play a major role in the case of any fire hazards.

• Surface propagation: The reaction to fire characteristics of the materials used within the external cladding system will affect the rate of fire spread up the building envelope by way of the surface of the external cladding system. By using fire retardant materials in cladding, we can avoid huge fire hazards.

• Cavities: Cavities may be incorporated within an external cladding system, or may be formed by the delamination or differential movement of the system in a fire. And this cavity may act as an insulation chamber between internal and external environment.

• Fire breakout: Following the initiation of a fire inside the building, if no intervention occurs, the fire may develop to flashover and break out from the room of origin through a window opening or doorway.

• Fire re-entry: Cladding system in window and door stops fire re-entry.

• Fire service intervention resistance. However, today, there are tested assemblies available from companies (such as Siderise and Hilti) that provide a warranty and certification for the same. Additionally, it is also important that the cladding material should not propagate and are non-combustible so as to limit the spread of fire along the external façade. There is a risk in fire conditions that composite panels are attacked at the joints or the panels suddenly delaminate and the metal facing fall away, thus exposing the combustible core which then intensifies and spreads the fire, observes Rajendra

Cover Story of limited combustibility. Cladding material which is rated for fire safety and fire performance, and those which normally incorporate an insulated core (such as sandwich panels), are apt for containing fire spread in a building, stresses Akash Saini.

Shah. The sudden increase in fire severity can accelerate the failure of the adjacent panels, so that if a fire does take hold, it can race up or through an entire facade of a building, causing a major hazard to occupants and a major property loss.

There is a lot of ambiguity in choosing the right materials due to consideration of inappropriate or inadequate information during procurement. Yes, overall in the industry, there is a significant shift from conventional materials to fire retardant (FR) materials, agrees Kanwar. HPL, even in standard grade, does not burn very well, or rather, do not ignite easily when exposed to flames and contribute relatively low in the event of a full scale fire. Flame

retardant HPL is manufactured with special halogen free additives that make it flame resistant, complying with Standard EDF-(EN 438-6 Fire Retardant). “More technically, fire resistance is the ability to retain the load bearing capacity (R), integrity (E) and insulation (I) properties for a defined period of time and it is useful to use REI properties while constructing buildings,” explains Kanwar.

The small-scale reaction test can also be done for cladding materials which provide better knowledge on reaction of materials. It’s also very important to check the products that are used in multi-storied buildings (18m or above) and they must be

The overall fire performance of the system is reliant on the interaction of all the elements used within the cladding system, i.e., rendered insulation, ventilated cavity cladding and built-up systems.

There were various tests conducted to check the performance of cladding materials. Talking about the building codes for fire and life safety, Devesh Kumar points out that in India we have National Building Code 2016 in Chapter 4 ‘Fire and Life Safety’, where it is mentioned to use façade with a fire rating of Class 1 in accordance to IS12777 and the material along with assembly to be tested for 2 hours.

Kanchwala too agrees that, as per Indian Standard code, the materials shall comply with the requirement of IS 1642 & IS 12777 having flame spread index matching to the requirements.

Devesh Kumar further adds that for fire performance test for resistance to fire, first we should have a 2 hour test from ASTM E119 and then the assembly should also pass either NFPA285 or BS8414. For resistance to fire EN13501-1 can test flame, smoke, molten droplets and heat released. The material to be used up to 15m building height should be Class B S1 D0 and above 15 m should be Class A2 S1 D0 in accordance to EN13501-1.

BS8414 is one particular test method which was specially developed to demonstrate under a simulated fire in a compartment breaking out of any opening in the external wall, the cladding system will not permit excessive fire spread up the building.

Cover Story Accordingly, each cladding material is rated for fire resistance, elaborates Keswani. However, there are certain suppliers, who provide samples for the test that differ from the material that is actually supplied to the project.

Hence, one should ensure that random samples are sent to the test

There are several tests being used globally for cladding materials depending upon the regions and building regulations: • ISO 9705 room test: Products are tested to simulate their end use application, so products which have different end use applications can achieve different classifications.

• The single burning item test (EN 13823) measures the spread of flame, heat release, smoke production and the extent of flaming, burning droplets.

• The small flame test EN ISO 11925-2 evaluates the ignitability of a product exposed to a small flame ignition source and measures flame distances, the burning time and any flaming droplets or particles generated.

• Large scale test • BS 8414 -1: 2002 is the test method for non-load bearing external cladding systems applied to the face of a building. The test determines the comparative burning characteristics of exterior wall assemblies by evaluating the characteristics: - Fire spread over the external surface - Fire spreads internally within the system being tested - Mechanical response, i.e. the degree of distortion.

Two available tests for HPL cladding materials: • BS 476: Part 7: 1997 - Class 1 results in this test means the HPL exterior cladding used is of good quality.

According to Class 1 test result, the spreading time and extent of fire over the tested panels are very slow. While Class 4 means quick flame spreading. So HPL with class 1 results are safe to use at our homes and buildings.

• REI Property – Fire resistance is the ability to retain the load bearing capacity (R), integrity (E) and insulation (I) properties for a defined period of time. In the construction of buildings, this is assessed for finished elements with structural functions (e.g. doors or walls) in which the HPL laminates are just one component. REI 30 or REI 60, here numbers show the time in minutes for which the HPL panels will retain their properties. So higher the numbers in REI properties, good and safer will be the HPL panels.

If the materials in an external cladding cannot meet limited combustibility requirements, then it is very important to demonstrate compliance with AD B by testing the cladding as a whole and satisfying the performance criteria in BR 135 (As per the guidelines mentioned in the requirements of Building Regulations in the UK, Part B Fire Safety). It is also very important to check the installation and testing of a complete cladding system, which allows materials themselves be combustible with meeting the requirement of BR 135 which helps in maintaining the appropriate safety standards (BR 135 Fire performance of external thermal insulation for walls of multi-storey buildings. 3rd edition BRE (2013).

Apt Cladding PREVENTS Spread of Fire The new concepts, materials and ways that have emerged in the millennial world tends to put aesthetics above safety quite a many times but fails to realise that aesthetic will follow the lead of safety in the long run. A properly tested, installed and maintained cladding can not only provide shelter from external factors, but can also be the reason that the fire never spread to

Cover Story the entire structure and was uprooted at its cause itself. Therefore, the cladding material should not facilitate catching fire at the surface and in worst case scenarios, when it does, it should phase away from the building to prevent fire from spreading to the vicinity thus, successfully preventing a disaster.

To decrease the risk of spread of fire through building facades, two options of passive fire protection could be considered, points out Kanwar – by using flame retardant treatments to improve the reaction to fire performance of the cladding material in the entire design and geometry of the façade; and by using How can apt cladding prevent spread of fire in building facades?

• Passive fire protection: It consists of slowing down the development of a fire and its rapid spread by using construction material with low flammability and combustibility.

• Fire and smoke stop: To stop the spreading of fire between floors, the gap between the building and the cladding system must be treated with 2hrs fire rating and sealant to stop the smoke.

• Vertical fire separation: Top stop the spread of fire between two rooms vertical fire separation is a must.

The separation shall be done using fire rated material with 2 hours fire rating.

• Cladding material: Selection of right material plays a major role in fire safety, there are many projects where lives are lost and lots of destruction happens due to use of wrong cladding materials. Cladding material must have Fr grade A2 class (No significant contribution to fire at any stage of the fire)

construction elements capable to avoid the contact between the fire plume and the combustible cladding.

The first axis of the so-called passive fire protection consists of slowing down the development of a fire and its rapid spread by using construction materials with low flammability and combustibility, explains Rajendra Shah. This measure is related to the reaction to fire of materials such as wall, floor, ceiling and facade claddings as well as materials that are in the vicinity of the exposed surface.

Passive fire protection relates to the building’s structure as well as to the building’s finishing and relies on the following principles: ● The use of cladding materials with good reaction-to-fire characteristics, in order to delay the development of an incipient fire. ● The realisation of compartmentation to confine the fire, for a defined period of time, to the compartment in which it started. A high fire resistant cladding material can achieve this to an extent. ● To preserve the load-bearing function of structural elements

(columns, beams, walls) during the fire, appropriate cladding material selection is important.

The key points regarding fire safety are to prevent spreading of smoke and fire in the building. Suitable fire stops and smoke seals play a crucial role in preventing the spreading of fire.

Additionally, fire retardant materials are used for external cladding. There is provision for necessary openings for safe evacuation & passage of smoke. The framing which holds the cladding makes it robust and prevents the structure from collapsing during a fire spread.

The Water Cube Stadium in Beijing, China

Consider the case of ETFE (ethylene tetrafouroethylene) panels at The Water Cube Stadium in Beijing, China. In the said case, the cladding material possesses this amazing property of “selfshrinking” or melting away from the structure, thus The Water Cube Stadium in Beijing, China letting the smoke out and in turn facilitating ventilation during a fire hazard. It is necessary in today’s scenario to consider materials with a low carbon footprint as well as recyclable materials.

Always remember the performance in testing relates directly to real fire performance, reminds Saini. So to know how to prevent the spread of fire in building facades, do the test under the simulated whole-room fire in a compartment being emitted from an opening in the external wall, the cladding system will not permit excessive fire spread up the outside of the building.

cladding?

Depending upon the architectural design of the building, the external cladding can play a significant role in the structural design of a building. The external factors such as high winds and rains play a crucial role in the selection of material for façades and its design. Also, high-rise buildings have a stringent regulatory requirement while designing the façades. Facades could be designed purely as aesthetic elements that are clad superficially on the buildings, or as a full blown structural component integrated with the building structure such as the

72

WFM l March - April 2018

750-seater auditorium that we designed for the Symbiosis University of Applied Sciences, in Indore.

What are the key factors to be considered while designing and selecting materials for cladding?

Cladding is often prefabricated in panels that are attached to the structural frame of the building. Cladding systems may include additional components such as windows, doors, gutters, roof lights, vents, etc. The nature of cladding selected for a particular building may depend on the internal and external conditions, durability, weather, site context, budget, maintenance, structural requirement, location sensitivity, fire safety, material availability, detailing ability to achieve water tightness,

cleaning ability, aesthetic quotient. High quality, well designed, properly installed cladding can help maximize thermal performance, minimise air leakage and optimise natural day lighting. This can help reduce the mechanical and electrical burden on a building.

What are the best suited products considering the Indian climatic conditions?

India has a varied climate depending on the geography, from warm and humid to cold and dry. Therefore, the best suited products could vary from place to place. Terracotta cladding is great for Indian weather conditions. The tiles modulate heat according to climate, their look imparts warmth, they are eco-friendly and a smart alternative to exposed brick masonry. Terracotta cladding is made of natural clay and comes with qualities like high durability, good UV resistance, acoustic resistance and heat insulation.

How can it provide better thermal insulation, at the same time support effective ventilation?

The cladding system should include thermal properties by controlling the radiation and conduction of heat. Thermal insulation is achieved with the use of appropriate material and detailing, and effective insulation is achieved through engineered integration of ventilation system into the cladding. Insulation on the inside of external walls is the best solution if insulation from outside is not an option.

Even older buildings with listed facades or those worth preserving often have low thermal insulation, which can be improved by more than 60 per cent by internal insulation.

Installation is also comparatively cost effective because no scaffolding is required for the building and it can be applied on a room by room basis. Maximum heat can escape through external walls if virtually unchecked. Many buildings are designed with double skin masonry for visual or structural reasons or as protection against extreme weather conditions. The cavity is given an insulating layer so that the cold air between the facing wall and the lining wall does not then cool the internal skin.

What is the role of cladding in controlling the internal environment and acoustics in a building?

The cladding system can control the internal environment of the building such as controlling light penetrating into the building, controlling the radiation and conduction of heat from the sun, etc. This is due to the solar gain through the glass panels. The internal temperature can be controlled by three ways. First is by using a deep recessed window in conjunction with external vertical fins. Secondly, by using non-transparent external louvers and thirdly is by using a special solar control glass.

ACP is a product that is widely used in India today, not just for commercial exteriors, but for interiors and residential projects too, and 80 per cent of the ACP market in India belongs to 3mm ACP. By bringing affordable 3mm fire rated ACP in the market, the company has played a crucial role in creating a fire-safe society.

Making buildings fire-safe has always been a concern. However, fire rating has largely been limited to 4mm ACPs for high-priced projects only. The fire rated 4mm ACP of Aludecor has been very popular with high-rises for a long time. Backed by this infrastructure, the R&D team of Aludecor worked out fire rating for 3mm ACP that can be offered to the market at an affordable price.

Providing 2-hour fire resistance, the product controls flame spread and heat release. It suppresses smoke so that visions of people are not blurred while escaping. It does not produce flaming droplets as well.

Addressing the dealers in Kolkata, Ashok Kumar Bhaiya, the CMD of Aludecor said that fire rated ACP is a kind of an insurance against fire for buildings. He added that this affordable 3mm FR ACP has been developed entirely in India, at their factory in Haridwar.

What inspired you to become an architect?

My father has always been an inspirational figure to me for his commitment to design. At a time when terms like “sustainability” and “environment friendly architecture” were yet to be coined, he emphasised the need for architecture that responded to the site and climate.

For example, the entire Jawaharlal Nehru University (JNU) campus was built on undulating, rugged terrain, and the design reflected this in its planning and choice of materials.

Face To Face studied in universities like Harvard and MIT. A visionary and a man ahead of his times, his contribution to architecture is truly motivating.

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

The essence of every design is its functionality supported by goals and possibilities. One of the most important factors to be considered while designing fenestration is the contextual climate considerations which is responsible for planning of optimal heat gain, sound privacy, zero water ingress, light, etc. In conjunction with this, the solutions for the fenestration design need to keep up with the architectural vocabulary and the theme of the project. This in turn is associated with the scale of openings. The window as a module can accentuate the building design horizontally and vertically. In addition to this, windows have to be designed for fire safety and seismic tolerances.

As designers we need façades which can change in response to light, temperature, humidity, noise and may be even pollution. Our projects use materials ranging from MS pergolas and structural glazing to RCC turrets, ACP and GRC. According to you, what is an intelligent façade?

A façade which integrates adaptable technology and is able to modify it for the ease of living in the building irrespective of the external environmental conditions or location could be termed as an intelligent façade. These façades show a dynamic behaviour and regulate energy flow according to the local climatic context, thus, maintaining the inside comfort requirement.

What about sustainability and environmental considerations when choosing the façade/ cladding material?

The aim of building façade/cladding material is to meet demands of ventilation, shading and energy conservation.

Face To Face one of its kind, and holds a fresh challenge for us. The prime property of any cladding material we choose, is its ability to support its own weight. Beyond complementing external appeal of the building, it should enhance overall thermal and acoustic properties of that building. Other considerations include climatic settings, comfort conditions to be achieved and maintenance over time. Modern trends bring to light a range of structural practices and lightweight building materials for the façade and cladding industry.

The “building skin” in this day and age, is beyond just glass and composite panels. The possibilities are manifold and the benefits may be modified as per client’s need.

allabh Bhawan is the State Secretariat of Madhya Pradesh, located atop the Arera Hill in Bhopal. Flanked by a large lake on one side of the hill and a green expanse on the other, the site for Vallabh Bhawan enjoys views of the natural, scenic beauty of its vicinity. These views are framed by an apparent visual axis created by the Vindhyanchal Bhawan and Satpura Bhawan on either side, with an exquisitely landscaped belt acting as the foreground.

The existing context reflects an amalgamation of modern architecture in the buildings and the traditional chaarbagh style landscaped gardens, commonly seen during the time of the Nawabs of Madhya Pradesh.

The design is inspired by the modern interpretation of the turrets, horizontal bands and stepped forms in the architecture around it. The concave, U-shaped form of the structure not only creates an inviting entrance, but also forms a seamless loop between the three primary buildings. Traditional architectural elements like chhatris, jaalis and colonnades have been given a contemporary flavour by using restraint and keeping the forms simple, so that the basic form may express itself. The eye catching sweeping forms

of the turrets are not easy to miss. In addition to this, modern elements such as fins, pergolas and solar panels keep the structure protected from the harsh sunlight.

To conclude, the design of Vallabh Bhawan aims to translate the rich cultural fabric of the state and bring it to the global stage using contemporary styles through architecture. This amalgamation of architectural vocabularies married together binds the glory of the past with the aspirations of a forward looking community to create a unique identity that embodies the spirit of the Madhya Pradesh.

A Unique Façade Assemblage Betasoft ITES Building, Mohali

I

TES, the IT building designed

by Ar. Sangeet Sharma of SD Sharma & Associates, is an interesting and a composed architectural project. As a plotted development, it was imperative to design a building which was most functional and eco-friendly. The longer sides were covered with the adjoining buildings so the essential lights was from front and back.

The plan is a block of two large halls/working spaces with the central vertical circulation. The central lobby

102

consists the entrance, staircase lifts and toilet blocks-there by giving two large halls an obstructive columnless space. The halls are oriented southwest in the front and northeast on the rear. The design challenges included a perfect environment conducive to IT and an area full of vigour.

The key principal design factor of this project is the consideration of the orientation. Being a plotted development the phases of the building faces South West (SW).

WFM l March - April 2018

The challenge was to consider this odd orientation and yet provide a solution. As glass was essential in the elevation, being an IT building that needed a global image. The glass louvre systems were used in the façade. Being in Chandigarh, these louvers were a constant feature to keep the hot sun of south and south west away. The louvers were designed, fabricated and installed in a unique assemblage. The protection from the harsh sun saves energy and the temperature is curtailed

Project Watch inside. This system is aesthetically very sound and provides cascading sociography on the façade.

The façade in totality is a

composition in itself by varying the patterns in every floor. It is comprised of uniquely designed glass louvers giving exemplary aesthetics and designed protection from the southern sun. The glass louvers are made using low e glass. The joints are minimal and the green glass is soothing for the eyes. The services are efficiently designed providing full safety to men and materials. The interiors are columnless uninterrupted free flowing spaces.

The building is eco-friendly based on its planning principles and orientation. This is a huge ecological consideration. The building is not a glass box and is efficiently designed

for ambient thermal and comfort conditions.

The biggest challenge was fabrication of the details of the façade. The louvers have not been implemented in this fashion in the buildings. This was overcome by intense and meticulous planning and detailing.

The client required a pent house on the top most floor and giving it an identity was an effort. This was overcome by intense thought and involvement.

ocated on a busy sectoral road of the city of Panchkula, Pool Yard House was designed for an elderly couple and their visiting family and friends. The design brief was to visualise a house exuding comfort designed for relaxation and leisure. The concept was to place emphasis on the courtyard and pool areas, with these acting as the focal point of the space.

The facade has been designed in two individual masses. A screen comprising vertical members that reduces visual contact with the busy street outside while allowing the occupants to have a view of the trees lining the road across.

Transparent walls link interiors to the outdoors

Another distinct mass is created by the staircase facade, clad in dark grey textured stone. Small rectangular void has been created in this facade to break the monotonous mass and add lightness to it. These small windows have been fitted with reflective glasses incorporated to add a sculptural dimension to it. A water body planned near the entrance sets a tranquil tone for the interiors.

Transparent walls have been used to interconnect the various spaces of the house, and to link them to the outdoors as well. The sitting room located at the front of the house is designed as an extension of the landscape with the cantilevered roof reinforcing the connection of the inside to the outside. The transparent walls are further used to accentuate the presence of the pool from different areas of the house.

The main staircase and the wellness areas have been connected to the rest of the spaces via the courtyard, establishing a strong correlation between the inside and the outside, a fact that achieves greater importance when the climatic zone characterised

Creating Harmony in Contrast Martin’s, Panchkula, Haryana

T

he project, located on an industrial site in Panchkula, India, presented a unique problem for the architects, necessitating them to come up with an unusual solution.

A furniture factory cum display centre and an adjacent building, both owned by the client needed to be visually connected so as to give them a common facia. The client wanted to present the viewer/guest with a unified front as far as the buildings were concerned. But as per the local by-laws, only metal fabrications could be used to achieve the same. Since, both the buildings had their own individual characteristics and different internal planning, no drastic measures could be employed. A method needed to be devised wherein the desired could be achieved without altering the existing design.

Finally, a concept was developed that would allow just that. An external screen of expanded metal mesh was unanimously decided as the best solution. Further, to make the design site sensitive, an additional layer of FRP panels was added, which

also helped in reducing south heat gain. The FRP panels were created in the industrial workshop of the furniture factory itself as the designers wanted the exterior to be synchronised with the core of the factory.

A mould was custom-made for the panels based on the inputs given by the client and design specified by the architect.

The dazzling yellow of the panels was deliberately decided upon to provide a contrast to the dull grey of the metal mesh. The unconventional design of the façade provides a relief from the monochromatic, regular surroundings.
