The document provides information about the ITC Green Centre in Gurgaon, India, which was the first building in India to receive LEED Platinum certification. Some key points: - The building uses various sustainable design features and technologies to reduce its environmental impact, saving over 50% on projected energy costs. - Examples include use of local and recycled materials, rainwater harvesting, green roofing, solar power, and efficient water and energy systems. - Its "L" shape and central atrium promote natural light and ventilation to reduce energy needs.

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)
• 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.

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.

• 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.

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.

13. • 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.

an “engineered rain garden”
that filters stormwater

microbes within the special
soil media to remove
pollutants.
collects stormwater runoff that
will be used to irrigate plants &
the “first flush” of runoff
from a parking lot typically
contains the most polluted
stormwater runoff; it will help
remove oil and grease.

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.

• 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.

• 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.

•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.
