21. 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 tress transplanted
▸ Excavated soil reutilized at other construction sites
and the zoo
ARCHITECTURAL CONCEPT
▸ Effective ventillation by Orientating The Building E-
W
▸ Optimum integration with nature Separating Out
Different Blocks with connecting corridors
A huge Central courtyard
Plan pedestrian axis to East, North and West entrance
without crisscrossing vehicles

22. TOWARDS ENERGY POSITIVE APPROACH - RENEWABLE
 Façade has been designed to receive 70% of natural day light
 Inner courtyard serves as a light well.
 Provision of solar photovoltaics
 Photovoltaic stepping towards the south side
 Shades the roof
Renewable Energy
Solar PV System of 800 kW capacity
Total Area: 6000 m²
Total Area of panels: 4650 m
No of panels: 2,844
Annual Energy Generation: 14.3 lakh unit
Shadding from summer sun while allowing in winter sun
ROOF OVERHANGING ACTS AS SHADING DEVICE
Façade of the building
Façade of Building
Roof overhang act as shading
device
Shading from summer
sun
While allowing winter sun

23. ENERGY POSITIVE APPROACH
Central courtyard helps in air movement as natural
ventilation
happens due to stack effect.
Brown and beige coloured stone
jaalis add to cross ventilation.
The terrace garden utilizes preserved top soil
extracted during the initial excavation

24. ENERGY POSITIVE
APPROACH
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
Polymer plastics grids turn the visual
asphalt fire tender road into a soft
paved space
Preservation of existing foliage
increasing the front set back.

25. SITE AND WASTE WATER
MANAGEMENT
To reduce landscape water
requirements
► Drip irrigation
► Use of native species of shrubs and trees
having
low water demand in landscapping
➤ Low lawn areas so as to reduce water
demand
►Reuse of treated water for irrigation
Reduce water use in building
►Dual flushing cistern
► Low discharge fixtures
► Waste water treatment
► Reuse of treated water for irrigation and
cooling towers of HVAC
► Rain water harvesting -efficient water use
during construction
► Appropriate shading from summer sun,while
allowing in winter sun
Drip irrigation

26. MATERIALS AND
CONSTRUCTION
TECHNIQUES
► Ready Mix Concrete with PPC having
more than 30% fly ash content - Fly ash
brick.
► Stone available in nearby area for
Terrazzo flooring
► AAC (Aerated Autoclaved Cement)
blocks.
► Renewable bamboo jute composite
material for door frames & shutters.
► UPVC windows with hermetically sealed
double using low heat transmittance index
glass.
► Use of high reflectance terrace tiles for
low heat ingress. Avoided aluminum as it
has high embedded energy Sandstone
jaalis, stone and ferro-cement jaalis Grass
paver blocks for ground water recharge
► Light shelves for bringing in diffused light

27. ENERGY CONSUMPTION ON SITE

28. Annual Energy Production & Consumption (kWh)
► Extra efficient Solar photo voltaic (SPV) proposed (Terrace and projections) =800 kW
► Energy produced in building/year = 14,91,000 Kwh
► Energy consumption for building/year = 14,21,000 KWH

29. Geo thermal heat
exchange system
►180 vertical bores to the depth of 80 meter all
along the building premises.
Minimum 3 meter distance is maintained
between any two bores.
► Each bore has HDPE pipe U-loop (32mm
outer diameter) and grouted with Bentonite
Slurry.
► Each U-Loop is connected to the condenser
water pipe system in the central air conditioning
plant room.
► One U-Loop has 0.9 TR heat rejection
capacity.
► Combined together, 160 TR of heat rejection
is obtained without using a cooling tower.
► Water pumping and treatment costs gets
eliminated.
► Saves cooling tower fan energy.

30. HVAC system Chilled
beam system
Chilled Beam
►160 TR of air conditioning load of the building is met
through Chilled beam system.
► Chilled beam are used from second to sixth floor.
This reduces energy use by 40 % compared to a
conventional system.
► HVAC load of the buildings is 40 m²/TR, about 50%
more efficient than ECBC requirements (20 m²/TR)
► Chilled beams save AHU/FCU fan power
consumption by approximate 50 kW.
► Fresh supply air is pre cooled from toilet exhaust air
through sensible & latent heat energy recovery wheel.

31. NET ZERO DESIGN
► IPB reduces energy requirements by 70%
overall by conventional
▸ N-S orientation - Limiting WWR (Window to wall
ratios)
► Insulation on wall and roof
▸ Extensive greenery to reduce heat load
▸ Maximizing day lighting to reduce lighting loads
▸ Extremly low lighting power density -5 w/sqm
► Planning to minimize AC loads (keeping open
atrium for cross ventilation, non conditioned
lobbies)
► Efficient HVAC with screw chillers, VFD'S,
Chilled beams
► Ground based heat exchanger for condenser
water
► Energy efficient appliances (5 star BEE -
Bureau of energy efficiency)
