The document discusses several green certified buildings in India. It provides details about the Development Alternatives headquarters in New Delhi, the first building in India aiming for zero emissions. It utilizes passive cooling and a hybrid HVAC system. The ITC Green Centre in Gurgaon is India's first LEED Platinum rated building, saving 53% energy and 40% water. It has a stormwater management system and uses fly ash bricks. The Indraprastha Bhawan government office building in Delhi generates all its energy needs from rooftop solar, making it India's first net zero building.

living ecosystem: a fine balance of
natural and man-made processes
employing environment friendly
energy, material and water
management methods.
o It is already becoming the
benchmark for green buildings in
India.

8. The primary strategy is to curtail heat gain through the
building fabric by ensuring favorable orientation with
respect to the sun’s trajectory and carefully designed shading
and insulation of walls, windows and roof. Secondly, the
building is "clothed" with plants on its eastern and western
faces and on the roof.

9. Displacement cooling – in which cool air is introduced at
the floor and return air is collected at the ceiling – reduces
energy consumption on two counts.
Hybrid HVAC - In the hot dry season the system would use
direct and indirect evaporative cooling, and in the humid
season refrigerant cooling.

10. Not a drop of waste water from DA will pollute the Yamuna
• The building actively integrates water saving measures on one hand
and on the other ensures that water is recycled and utilized in
irrigation of the landscape and all surplus treated waste and rain water
is sent into ground water recharge within the site to help maintain the
depleting water table in the urban areas.
• Waste water and sewage from kitchens and toilets will be recycled and
the surplus used for ground water recharge and the slurry/sludge used
for manure.

Efficient devices such as water conserving
faucets and showers.
• These water features
serve a purpose; they
are designed to cool,
to enhance the
environment visually
and aurally.

11. 11
The building also uses the earth excavated from the site, materials recycled from the earlier
HQs, as well as y-ash waste from local thermal plants for masonry infill walls.
• stone instead of vitrified tiles for floors.
• exposed brick finish without paints.
The earth removed from the site after the demolition of the original building was
recycled into compressed earth block using simple machinery. The fly-ash
blocks used in the building were made using fly-ash from a local power plant.

MEASURES FOR SITE
• Wider Front Setback (22m) to protect front tree line
• Preserve the integrity of the green street
• Preservation of the local ecology, Tree Cutting approvals for 46, but only 19 cut
• - 11 Trees Transplanted
• - Excavated Soil reutilized at other construction sites and the Zoo
• The IPB office building for the ministry of
environment and forests has been planned in 2
parallel blocks facing the north south direction,
with a large linear open court in the Centre.
• The Building blocks create a porous block form to
optimize air movement throughout the site and the
NS orientation allows for optimum solar access
and shading.

16. 16
• The Courtyard helps in air movement besides being a
shaded interaction space.
• Effective ventilation by orientating the building E-W and by
optimum integration with nature by separating out different
blocks with connecting corridors and a huge central court
yard.
• More than 50% area
outside the building is
soft with plantation
and grassing.
• circulation roads and
pathways soft with
grass paver blocks to
enable ground water
recharge

17. 17
• Chilled beams are used in the building. Room
temperature maintained is 26 degree Celsius. Chilled
beams with drain pans are used to drain out water
droplets due to the condensation during monsoon.
• 160 TR of air conditioning load of the building is met
through chilled beam system.

Mgmt. Strategies

19. 19
Optimize building design to reduce
conventional energydemand.-
• Energy efficient light fittings to reduce
energy demand
• Part condenser water heat rejection by
geothermal mechanism. This will also
help in water conservation in cooling
towers for hvac system
• Entire hot water generation through solar
panels.
• Maximum day lighting
• Regenerative lifts.
• Use of lux level sensor to optimize
operation of artificial lighting.
• Solar powered external lighting.
Highest efficiency (20%) solar PV panel grid interactive
system has been installed in the building. Annual energy
generation (14.3 lakh units) is taken care of by solar PV
panels
Provision of Solar Photovoltaics for Net Zero
requirement also Shades the Roof.

ITC GREEN CENTRE
•Location : Sector 33, Gurgaon, India.
•Climate : Composite
•A LEED PLATINUM Certificate building with
56/69 points
•Area : 15,799 Sq. m (out of which 9294 sq. m –
conditioned area, 6505 sq. m non-conditioned
area)
•The first ‘Platinum’ rated building in India and has endeavored to adopt green practices
that go beyond recycled waste.
•One of the strongest aspects of ITC green Centre is its design.
•All systems are integrated an a way so that they can function as naturally as possible.

31. 31

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

32. 32

33. 33
SITE SELECTION AND PLANNING:-
L’ shape design with main entrance
towards North.
Longer axes along NE and NW.
By ‘L’ shape configuration, the width
of the floor Plate is reduced for the
same amount of floor plate area there
by allowing natural light to penetrate
deep into the interior spaces.
It also ensures that one part of the facade 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.

34. 34
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 façade Atrium(interior)

ENERGY EFFECIENCY :-
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.

36. 36
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.

37. 37
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.
•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.
