1. SolarEnergy Centre,GualPahari,Gurgaon

2. The complex is located
in Gurgaon, about 35
km south of Delhi
that lies in a composite
climatic zone. The
buildings in this
complex have been
divided into three
groups.
1. The technical and
administration
block.
2. Workshop building
and electrical sub-
station, etc.
3. The guest house.

3. Roof And Wall Treatment
1. The building was conceived
as a low spread out
structure, arranged around
courtyards, maximising the
use of roof surface for
evaporative cooling system
with automatic controls.
2. For comfort cooling, the
strategy used was to
reduce ingress of heat by
using hollow, concrete
block walls, properly
shaded windows, and a
reflective finish on the
roof surface.

4. Windows for day lighting
1. Special open able louvered shutters were designed for the
eat and west facing windows.
2. Aluminium windows were used in preference to steel windows
as this gives tighter fitting with lesser infiltration.
3. To provide day lighting in all the work areas and to ensure
that no artificial lights are being used during day time, all
the deeper office rooms have been provided with windows on
two different sides.
4. The windows have been properly shaded to reduce glare
from the sky.
5. All rooms have been provided with windows so that they will
receive sunlight for atleast half the day in winter.
6. The monsoon season merits special consideration, as
evaporative cooling does not work during this period. In these
buildings, cross ventilation has been provided in all rooms.

6. Ventilation anddaylighting
1. Permanent ventilators have been
placed on the south side, the roof is
insulated two – level windows have
been provided for good ventilation.
2. To prevent heat gain through the
roof, it has been given a reflective
white finish.
3.The entire building is day lit and no
artificial lighting would be required
during normal working hours.

7. The guest house
1. The first building to be put
up in the Solar Energy Centre
campus, this has an earth
shelter cooling system. Solar
water heaters have been
integrated with architectural
design.
2. Winter heating is direct by
sun lighting of the guest
rooms. Each window is
provided with an arched
sunshade, which allows winter
sun to come through the top
part of the glazing.
3. Solar water heaters provided
in each toilet have been
integrated with the
architectural design.
4. A sunny terrace for solar
cooking has been provided
near kitchen.
