DESIGN
BUILDING DESIGN
Two office wings are held together by an octagonal central atrium to give it a large L- shaped form surrounded by an exterior landscaped court with entrance
facing the north.
This L- shape configuration reduces the effective floor width and allows more natural light to penetrate deeper into the building.
BUILDING
DESIGN
The L-shaped blocking also ensures that some part of the façade is always shaded so the load on air-conditioners is reduced.
The central atrium column of glare-free natural light to form in the heart of the building and encourages a sense of community and employee interaction.
BUILDING MATERIALS
It achieved a platinum LEED rating at a time when the LEED certification wasn’t even customized to the Indian conditions and priorities. A lot of effort, of course, went into realizing this dream and USGBC cooperated fully to help ITC in their endeavor.
BUILDING
MATERIALS
GLASS
The designers did not want to use reflective glass, whose mirror-like surface repels the heat by reflecting it back to the surroundings in a distinctively unfriendly ecological manner.
It was the endeavor of the designers to use an energy-efficient glass for the building since the fundamental requirement of a good work environment is to offer natural light and clear visibility, and only glass can achieve that.
GLASS
250mm thickness of the building’s walls, the double glazed windows and high performance glass reduce the amount of solar heat entering the building by more than 65%.
The special double–glazing glass used in the ITC Green Center allows maximum natural light in while blocking most of its heat content, thus burden on air-conditioners is reduced. This is the best solution for composite climatic conditions.
FLY ASH
The building has used many recycled and recyclable materials like fly ash based concrete and bricks, etc. In fact, Over 10% of the construction material, such as glass, ceramic tiles, steel and aluminium, used in the building are recycled, refurbished or salvaged from other sites.
LOCAL
MATERIALS
It was a conscious effort to procure as much building material as possible from the nearby sources to reduce the impact of material transportation on the environment. More than 40% of the material was procured from within 500 miles of the site.
LOW
EMITTING MATERIALS
Adhesives and sealants having low VOC (volatile organic compounds) levels are used for carpets, composite woods and paints in the interior.
LOW
EMITTING
MATERIALS
WATER EFFICIENCY
Interlocking tiles placed across the landscape of the building to harvest rain water through the grass that grows between the tiles while ensuring 0%
surface run-off.
Water is treated and recycled to be used for irrigation purposes to ensure zero discharge into municipal drainage.
WATER
EFFICIENCY
Harvest 100% of the rain that falls on the building, and recycle 100% of all the water used in the building including waste water.
Annually, storm water pits recharged ground water by around 5500 kilolitres and sewage treatment plant recycled 6900 kilolitres of water in total.
40% less water consumption through low discharge fixtures.
Water treatment procedures to ensure 40% of required potable water.
ENERGY EFFICIENCY
ENERGY
EFFICIENCY
- The high albedo roof coating with 0.94
emissivity reduces the amount of heat
absorbed by reflecting over 90% of
visible and infrared radiations away
from the building.
- Sensors pick up the presence of additional numbers of people and fresh cool air is pumped in and out of rooms accordingly.
- Rooftop solar panels provide energy for hot water within the building and for all the neon signs and some of the night lighting. Only T-5 lamps, which are energy efficient, are used.
- The ITC Green Center achieves a 53% saving on energy consumption, a real feat at the time it was built.
- The building uses efficient light fixtures with electronic ballast. Solar photovoltaic cells on the roof are used for water heating and emergency lighting.
