Sustainable Architecture About ITC Green Centre Location: Sector 33, Gurgaon, India. Climate: Composite a LEED PLATINUM certified building with 56/69 points Area: 15,799 sq m (out of which 9294 m² - conditioned area, 6505 m² - non-conditioned area) 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. 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.

Sustainable Architecture 1. Site Selection & Planning Sustainable Architecture

Sustainable Architecture 1. Site Selection & Planning 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 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. Sustainable Architecture

Sustainable Architecture 1. Site Selection & Planning Atrium (interior) Entrance facade 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.

Sustainable Architecture 2. 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. Use of waterless urinals in the building. The urinals use biological blocks containing particular bacteria that reduce odour problems and blockages in the urinals that saves 3 lakhs litres of water per annum. Annually, storm water pits recharged ground water by around 5500 kilolitres, and sewage treatment plant recycled 6900 kilolitres of water in total. 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. Sustainable Architecture

Sustainable Architecture What is Storm-water Management ? Stormwater is water that originates during precipitation events and snow/ice melt. Stormwater can soak into the soil (infiltrate), be held on the surface and evaporate, or runoff and end up in nearby streams, rivers, or other water bodies (surface water). Storm-water management : control of flooding and erosion. control of hazardous materials to prevent release of pollutants. planning and construction of stormwater systems so contaminants are removed before they pollute surface waters or groundwater resources. protection of natural waterways. education of a community about how its actions affect water quality, and about what it can do to improve water quality.

Stormwater Pond and Irrigation Pump Storm-water Management ? Impervious surfaces in the form of roofs, sidewalks, and parking lots that can create large volumes of storm-water runoff during rain events. Pollutants from storm-water runoff include oil and grease, excess nutrients , harmful bacteria, trash, and sediment, which can have negative impacts on water quality for the aquatic ecosystems and other uses, including drinking water resources and recreational uses of downstream water bodies. Components Bio-retention Cells Stormwater Pond and Irrigation Pump Oil/Water Separator an “engineered rain garden” that filters stormwater runoff utilizing plants and microbes within the special soil media to remove pollutants. the “first flush” of runoff from a parking lot typically contains the most polluted stormwater runoff; it will help remove oil and grease. collects stormwater runoff that will be used to irrigate plants &

Sustainable Architecture Storm-water Management ? If every campus did the following: reduce nutrient loading. reusing stormwater. reducing potable water use in its heavy chemical and energy use. solve water pollution in major urban centers. recharge air column with moisture to help cooling to mitigate warming climate. not only recharge local aquifers, but stop filling up the oceans with runoff to slow sea level rise.

Sustainable Architecture 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. 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%. Sustainable Architecture

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. Sustainable Architecture Sustainable Architecture

Sustainable Architecture 4. Building Material & Resources 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. fly-ash bricks & concrete Sustainable Architecture

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.

Sustainable Architecture 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. Sustainable Architecture
