ARCHITECTURAL PLANNING AND LANDSCAPING
• 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.

ARCHITECTURAL PLANNING AND LANDSCAPING
•The Building Envelope has been designed
i) to receive 75% of natural daylight to reduce energy
consumption.
ii) Access Friendly to differently-abled persons.
•Out of total 79 trees
existing on the site ,
only 19 were cut, and
11 transplanted
ARCHITECTURAL PLANNING AND LANDSCAPING
•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

CHILLED BEAM WORK AT SITE
In the IPB project Chilled Beams are being installed in
second floor to sixth floor.
 Chilled Beam Water in Temperature is 16° C and
water out temperature is 20° C.
 Room temperature maintained is 26 ±1 ° C.
 Chilled Beams with Drain pan are used to drain out
water droplets due to condensation during monsoon.
 160 TR of air conditioning load of the Building is met
through Chilled Beam system.

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.

Creation of this additional space(6000 minus 2200 m2)
in a multistoreyed building with restricted plot & roof areas
where no structure including surface parking is provided around
the building, was a big Constraint
