• 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
N- S orientation allows for optimum solar
access and shading.

ORIENTATION OF THE BUILDING-
•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

Optimize building design to reduce conventional energy demand.-
• 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
• variable chilled water pumping system through vfd.vfd on cooling towers
fans and ahu.
• pre cooling of fresh air from toilet exhaust air through sensible & latent heat energy recovery wheel
• entire hot water generation through solar panels.
• maximum daylighting
• regenerative lifts.
• use of lux level sensor to optimize operation of artificial lighting.
• solar powered external lighting.
Optimize energy performance of building within specified comfort limits-
• Reducing energy consumption (compared to GRIHA benchmarks) while maintaining occupant
comfort:
• For achieving visual comfort:
• Direct line of sight to the outdoor environment to vision glazing for building
occupants for more than 90% of the occupied spaces.
• Avoiding Deep floor plates to create maximum daylighted spaces.
• Landscaping planned with native species and water body features in central
court and all around the building.
• For achieving thermal comfort:
• All circulation spaces or passages were naturally ventilated / shaded / not air
conditioned.
• Energy Efficient Chilled beam based Cooling system proposed together with
condenser water cooling through ground pipes.
• Openable windows were proposed in conditioned areas to be able to utilize
favourable outdoor conditions.
• Insulated Walls through using an integrated AAC + Rockwool combination
together with high efficiency DGU’s and UPVC.

• 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).
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.
