Wienerberger’s Porotherm Clay Bricks promote green building…


Why is Porotherm Green?Wienerberger India has always believed in the concepts of sustainability through all its endeavors, right from procuring raw materials, to the production methodology and the products that we offer, are all bound by principles of sustainability. Some of the initiatives in this respect includes:

1) Disilting of Clay Tanks2) Use of locally available products3) Use of waste products from other industries4) Efficient use of Biomass & other environmentally friendly fuels in manufacturing

Apart from these, we continuously recycle heat & energy in the production process and systematically adopt various conservation projects in our plant on a regular basis.Wienerberger products (Porotherm HP, THERMOBRICK) has been rated by the Indian Green Building Council (IGBC) & GRIHA (Green Rating For Integrated Habitat Assessment) developed by TERI (The Energy and Resource Institute) two of the premium organizations dealing with green building in India.

The IGBC-LEED rating system has been developed based on guidelines of USGBC and promoted by CII – Confederation Of Indian Industries. We are happy to inform that POROTHERM HP Clay bricks are rated by IGBC under following criteria’s:

• Energy Efficiency : Lower ‘U’ values assure better thermal insulation thus providing comfortable indoor climate – reduce energy demand for air conditioning

• ‘U’ Value : 1.0 W/m²K• Material with Recycled Content :

• Raw Material used are industrial waste or recycled materials – thus save on natural resources Eg. coal ash, rice husk, granite slurry etc.

• Regional Material : Factory to site distance < 400km• In addition we use De-silted Clay from dead water tanks

GRIHA Green Rating For Integrated Habitat Assessement is a rating system developed considering Indian Climate Zones and inhabitants requirements indigenously. It is developed to rate commercial, Institutional and Residential buildings in India, emphasizing national environmental concerns, regional climatic conditions and locally available solutions.

Indian School of Business (Institution), HyderabadLeed Rating : Gold

The Housing Tower One [HT 1] is a 20 storied LEED Gold [NC] certified Residential building in the ISB campus at Gachibowli, Hyderabad.

The plan comprises of two apartments on each floor, connected by the main and service cores and separated by an inner courtyard. This planning strategy enables the two cores to contribute significantly to the structural stability of the tower and makes it possible to have large cantilevered balconies, structured with vierendeel girders with end verticals.

Each apartment has large balcony / terrace spaces that create a varying rhythm on the facade allowing one to go beyond the “extruded elevation” so typical of high rise apartments. The aesthetic of the building is derived from functional and creative moves that are intrinsic to the planning rather than an external application of elements.

The concrete mix design ensures early strength to structural elements to minimize

shuttering stripping time and Porotherm hollow clay bricks reduce the dead load for economical use of Fe 500 grade steel reinforcement.

The building responds to the local climate by orientation and thermal mass and at the same time, it relates to the main campus by way of its strong massing and color scheme. The building achieves its green status through the deployment of pre-dominantly passive means – UPVC windows with performance glass, rain water harvesting, water-saving fixtures, solar energy, effective cross ventilation and adequate natural lighting.

Housing Tower One is a sustainable tall green building with quality residential and social spaces that encourages responsible living and social interaction amongst its community


Project Name: Puma StoreType: Retail OutletArchitect: Studio DeCode Location: BangaloreWall Area: 4250 Sft

PUMA has launched their first sustainable store in Bangalore, India making it an exceptional retail experience. It is the first one globally that will revolutionize the concept of retail spaces. The 800 sq meters space has been designed in a way where every element has been locally developed and sourced. It incorporates a number of revolutionary and innovative design strategies to ensure significant energy savings and environmentally friendly practices. The lower levels serve as a retail area and a ‘PUMA Social Club’ cafe and bar is located on the upper floor and terrace.

The sustainable features of the store include:

• Recycled steel from old DVD players, bicycles and tiffin boxes to construct the building.

• Porotherm blocks used to construct the shell of the building have been made using silt from the lakes in Kunigal.

• The Store’s roof garden keeps the building insulated from the direct heat of the sun and the plants lower the temperature.

• More than 90% of the interior spaces in the store have direct access to natural daylight.

• The artificial lighting used in the store is energy efficient with fewer watts being consumed for the same lumen output.

• The highly insulated building shell allows for cooling without an air conditioning unit.

• Cooled air is taken from the earth 12ft below AFF through an air tunnel as it is equal to the average ambient temperature.

• The sustainable PUMA Store is 100% solar-powered as solar photovoltaic cells provide 10,384 kwh units of energy per year.

• Under Floor Air Distribution helps to save energy. This system works on the principle that air in any particular space needs to be

cooled only for the first eight feet from the floor because currents cause hot air to rise automatically while cool air remains at the

bottom.

• The furniture and fixtures in the store are made of recycled wood, while low VOC paint has been used to paint the walls of the

store.

• Occupancy sensors provide automatic on/ off control so that lights are used only when the room is occupied. .

Project Name: Geojit BNP Paribas Type: Commercial BuildingLeed Consultant: M. SELVARASULocation: KochiPorotherm Bricks Used: Over 140,000

The landmark building is constructed keeping in

mind the environmental health, sustainability and

the comfort of the occupants. It focuses on

efficient energy management and low water

consumption and will generate less waste

materials, thus creating a space for a healthy work

environment. The building that boasts of

1,04,580sqft area is expected to consume 25%

less energy than other conventional buildings.

It has incorporated spectrally selected high performance windows, Porotherm clay bricks, efficient air conditioning

equipment and low energy consuming lighting fixtures.

The windows, which are few in numbers, are carefully positioned so that they provide ample daytime light in the perimeter areas and at

the same time reduce the total heat gain in the building. The external walls of the building are built with 20cm thick Porotherm

clay bricks, which have a better u-value than conventional clay /solid / fly-ash / cement mortar bricks.

The glass windows are double glazed units (DGU) having 6mm air gap between the two layers of glass with SHGC 0.22, while the

exposed roof, especially the top floor roof, is insulated with 20mm thick thermocol under-deck insulation. The use of efficient water

cooled chillers in the building help reduces the energy load on air-conditioning. The ventilation system is designed to provide 30% more

fresh air than ASHARE 62.1:2004 standards, thus improving the indoor environment quality and occupant well being. All air handling

units are equipped with Variable Speed Drives (VSD) and MERV (Minimum Efficiency Reporting Value). To save on energy

consumption, the building is fitted with occupancy sensors in non-regularly occupied areas and has an average LPD (Lighting Power

Density) of 0.65 watts / sqft. In the building interior, all light fixtures are LED based.

The building does not use any lighting for façade and use only full cut off lamps for exterior illumination. In addition, all computers are

energy efficient and TFT monitors are used. Also installed are treated fresh air units (TFA) with heat recovery wheel which will enable

the building to maintain the desired fresh air quantity as well as reduce its energy consumption. The TFA system is based on demand

control ventilation that regulates the amount of fresh air admitted to each occupied place, depending on CO2 level sensed through

sensors placed in all occupied areas.

This leads to greater energy conservation and efficient management of the TFA. To ensure the good environmental quality

and safeguard the building occupants’ health, only low emitting materials are used, like low VOC paints, adhesives &

sealants and all engineered wood free from urea formaldehyde resins. Water sustainability too is an area that was

focused on.

The new building has rainwater harvesting facility, low flow dual-flush toilets and other water efficient fixtures. Most of the

construction debris was reused or recycled to leave minimal imprint on the environment.

Geojit BNP Paribas met all the seven points of prerequisites to apply for LEED rating under various categories

like sustainable sites, water efficiency, energy, materials & resources and indoor environment quality. Geojit BNP

Paribas team is looking forward to setting a new landmark in Kochi, continuing its tradition of caring for the

welfare of its customers, employees and the environment.

Thank you!
