Suzlon One Earth, Pune This significantly unique office is designed by Christopher Charles, Pune based architect and has received LEED Platinum rating in 2010. He and his partner came up with the concept “Office in the garden”. Spread over 10 acres, this magnificent structure is one of the largest green building projects of the country and is also one of the India’s first buildings to be LEED (Leadership in Energy and Environmental Design) certified. Suzlon One Earth, Pune Suzlon one earth is 100% powered by onsite and offsite renewable sources. The campus has 18 hybrid wind turbines that fulfil 7% of the total energy consumption, the rest of energy demand is met from offsite wind turbines. The structure is designed in a way to ensure maximum daylight exposure thereby reducing artificial lighting consumption. The infrastructure within the campus is designed to enable water percolation and thereby control storm water runoff thus, contributing towards an increased water table level.

-Daylight Panel: PLT T (Pristine White) in (6mm - 12mm - 6mm)
• Energy Efficiency- 56% savings from the base case was achieved.
• Daylighting - 70% of the overall floor plate was daylight with daylight panel.
-100% of the work area is perfectly daylighted.
• Additional points achieved through glass - Regional material: Glass manufactured in
sriperumbudur plant and processed near by the project site.
- Recycled material: Glass is 100% recyclable. Cullet glass (broken glass) is used for glass
manufacturing. The percentage of broken glass is 18% of which 6% is sourced from post-consumer
waste.

11. • Other Design Features
- Radiant Cooling exploited for one the blocks.
- Radiant cooling found more efficient than normal cooling.
- Water use reduction by 48%.
- Low flow faucets & water closets.
- Over 80% of the construction waste diverted to landfills.
- Low VOC adhesives, paints and coatings.
- Treated waste water used for irrigation & air conditioning makeup.

12. • Role of Glass
- The combined use of PLT TG and SKN 444 II - high performance double glazed Saint-Gobain Glass
has been coupled up with the ideal orientation of the building, limiting the facades opening to the East
and West (where the direct morning and evening sun strike).
- The long faces of the building have been oriented towards north and south with shading devices
provided adeptly, especially towards the south.
- The narrow floor plate of 16m made it possible for 84% of the regularly occupied spaces to have
adequate day-light.
• Energy Consumption
- The building is 40% more efficient than the globally accepted ASHRAE standard. While the ASHRAE
standards for heat gain is 0.9W/sqft, SDB1 managed a .4W/sqft.
- The building has an efficient envelope - with a double walled insulation and an insulated roof with
reflective tiles. The heat gain of the envelope has been calculated to a 1W/sqft.

13. • Role of Glass
- The combined use of PLT TG and SKN 444 II - high performance double glazed Saint-Gobain Glass
has been coupled up with the ideal orientation of the building, limiting the facades opening to the East
and West (where the direct morning and evening sun strike).
- The long faces of the building have been oriented towards north and south with shading devices

• Material
-18% of the total value of materials in the building has been made out of recycled materials. By
regionally manufacturing 38% of the total project material by cost, the minimisation on transportation
has led to reduced pollution

and forests for construction of
new office building at new delhi.
• The basic design concept of the
project is to make the net zero
energy green building.
• PLOT AREA:9565sq m
• MAXIMUM GROUND
COVERAGE:30%
• F.A.R:200

• (18726 m2 – superstructure &
12675 m2- Basement)
• Year of completion : 2013
India’s first net zero building
This means that this is a building with zero net energy consumption where the total
amount of energy used in the premises on an annual basis is more or less equal to
the amount of renewable energy created on the site.

28. ACHIEVEMENTS

• zero electricity billing
• 55% savings in water
• largest roof top solar power
system in any multistoreyed
building (930kwp)
• first in government sector
targeted for both ratings of green
building (5star griha leed india
platinum)
• 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
LAYOUT PLAN

29. ARCHITECTURAL DESIGN STRATEGIES
• Building form wrapped around a pedestrian-friendly shaded green open courtyard
• A continuous green axis from front of site across the atrium.
• Eco park within the courtyard shall contain a self sustaining low.
• Large openings in building form on South and North sides.
• Conservation of natural soil and trees.
• Orientation of building has been planned reduce ingress of solar radiation.
• Large openings North and South faces.
• Green areas have been developed on smaller terraces.
• Shaded landscape areas to reduce ambient temperature.

•Use of native species of shrubs and trees having low water demand in landscaping
•Low lawn area so as to reduce water demand.
•Reuse of treated water for irrigation
Reduce water use in the building-
55% reduction in overall use of water. This was achieved by using:
•Low discharge fixtures
•Dual Flushing cistern
•Waste water treatment
•Reuse of treated water for irrigation and cooling towers for HVAC
•Rain water harvesting
Efficient water use during construction-
•Use of curing compound

Adoption of energy efficient ‘chilled beam’ system of air conditioning has resulted in reduction
of energy conservation by 40%.
This is an innovative air conditioning system, where air conditioning is done by air flow through
diffusers and chilled water is circulated right up to the diffuser points.

Chilled Water Supply Pipe (½” dia.)
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.

37. GEOTHERMAL HEAT EXCHANGE
• There are 180 vertical bores at the
Depth of 80 meter all along the
Building Premises. Minimum 3
meter distance is maintained
between any two bores.
• Each bore is lowered with HDPE
pipe U-loop (32mm outer Dia.) and
grouted with Bentonite Slurry.
• Each U-Loop is connected to MS
Header Pipe(100mm Dia.)which
finally joins the Condenser Water
Line in Plant Room.
• Condenser hot water is sent at
100°F (37.8° C) & back at 900 F
(32.2° C).
• One U-Loop has 0.9 TR Heat
Rejection capacity, so all together
160 TR of Heat rejection is obtained
without using a cooling tower.
• Enormous water saving since no
make up water is required.
• • Make up water pumping &
treatment cost get eliminated.
• • Saves cooling tower fan energy.

39. MATERIALS
•Stone available in nearby area for flooring
•Terrazzo flooring with locally available stone
materials.
•Jute bamboo composite for door frames &
shutters.
•UPVC windows with hermetically sealed double using
