Leed rated buildings who have used Porotherm HP:

1. Indian School of Business, Hyderabad

– Porotherm Horizontally Perforated Clay Bricks

gosmartbricksporotherm_ Porotherm Clay Brick

The Concept Note for ISB, Hyderabad:

The Housing Tower One [HT 1] is a 20 storeyed 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 colour 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.

The Concept Note for PUMA Store, Bangalore

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.

There are many incredibly innovative features that make this retail space environmentally friendly. It serves as a teaching model on how materials can be utilized locally or recycled to construct a building. In addition to building materials, energy conservation has also been minimized. Integrating photovoltaic panels on the roof harnesses enables the sun’s energy to be utilized for the lighting and cooling systems of the retail space.

The Concept Note for Geojit BNP Paribas, Green Building, Corporate office, Kochi

It has incorporated spectrally selected high performance windows, Porotherm clay brick, 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 brick, 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
