About ITC Green Centre Location: Sector 33, Gurgaon , India. Climate : Composite a LEED PLATINUM certified building with 5 6/69 points Area : 15,799 sq m (out of which 9294 m² - conditioned area, 6505 m² - non-conditioned area) One of the strongest aspects of ITC Green Centre is its design. All systems are integrated in a way so that they can function as naturally as possible. the first 'Platinum' rated building in India and has endeavored to adopt green practices that go beyond recycled waste and day-lit offices. Within a built-in area.
About ITC Green Centre Green features incorporated in the new building are- 0 water discharge 53% energy savings 40% reduction in potable water use use of treated grey water for flushing and landscaping fly-ash bricks & concrete alternative transportation facilities storm water management system solar thermal technology reflective high- albedo roof paint separate smoking rooms with exhaust system has a 30% smaller carbon footprint with the use of sensible technologies
Delhi-Jaipur Expressway Located in the commercial sector Airport & Railway station are about 35 kms (1 hour) far from the site.
Sustainable Architecture 1. Site Selection & Planning
1. Site Selection & Planning It also ensures that one part of the façade is always in the shade, preventing too much heat from entering the structure. The cooling effect is supported moreover by the discreet bodies of water placed in front of the building. L’ shape design with main entrance towards north. Longer axes along NE and NW directions. By ‘L’ shape configuration, the width of the floor Plate is reduced for the same amount of floor plate area thereby allowing natural light to penetrate deep into the interior spaces. Constructed on a 2 acre plot land, & has G+3 floors & G-2 basement floors
The central atrium allows a column of glare-free natural light to form in the heart of the building, thereby reducing the use of artificial light. The atrium also connects the various parts of the building to each other, both horizontally and vertically, it encourages interaction between the various parts, and more, it promotes a sense of community. Entrance facade Atrium (interior) 1. Site Selection & Planning
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%. 3. Energy Efficiency The high albedo roof coating reduces the amount of heat absorbed by reflecting over 90% of visible and infra red radiations away from the building.
3. Energy Efficiency Annual Consumption (lighting) – 121301 KWh Lighting Performance Index – 13 KWh/ Sqmt /annum Annual Consumption (A/C) – 596829 KWh HVAC Performance Index – 64 KWh/ Sqmt /annum With a consumption of 1.14lakhs kW/hour against an estimated 2.33 lakhs kW/hour ITC saved 51% of their total budget: 81% on lighting, 40% on Heating, Ventilation and Air Conditioning (HVAC) and 40% on hot water annually. This building has saved Rs.1 crore in power cost annually.
Over 40% of the materials used in the construction of ITC Green Centre was available within 80 km of the building site, which is not only cost effective but also offers the chance of easy renewal. More than 10% of materials used to make work-stations, cabinets, conference tables, wall panels and door frames was refurbished from other building sites. Over 10% of our construction material, such as glass, ceramic tiles, steel and aluminium , used in the building are recycled. There are storage bins on every floor of ITC Green Centre for recyclable materials like paper, cardboard, glass, plastic and metals, affirming commitment to ‘reduce, reuse and recycle’ and making it a point of everyday practice. 4. Building Material & Resources
Indoor Environment Double glazing window. The glazing for the building has been designed to maximize the effect of natural light, largely eliminating the need for artificial light during day time. The high performance window glass, while allowing light inside, does not allow heat and also keeps office cool from inside during the day decreasing the load on HVAC systems.
Indoor Environment Luminaries used – mostly CFLs and T5 lamps in mirror optic fixtures, 36W fluorescent lamps and magnetic ballasts are used in storages, electrical and mechanical rooms. The LPD (7.2W/m2) is less than the max allowed LPD (10.8W/m2) which is very good. CFLs provide the same amt of light as an ordinary bulb using 75% less energy. Good natural light available in office spaces. This building uses CO2 Monitoring system to improve the quality of the air to provide the fresh air.
