The document discusses two case studies of buildings designed for climate responsiveness: 1. The Bidani House in Faridabad, India, which uses a courtyard design, buffer spaces, and local stone construction to provide thermal comfort year-round in the region's variable climate. 2. The PEDA Building in Chandigarh, India, which uses overlapping floors, cutouts for ventilation, integrated solar panels, and a central wind tower to passively condition the large interior space and provide daylighting. Both projects demonstrate passive design strategies for responding to local climates through building form, materials, and natural ventilation techniques.

2. The Bidani house is a project that demonstrates a situation where a climate responsive
form and design was achieved in an existing urban situation with a fixed site size and
orientation. Faridabad, located in the ‘composite climate’ zone, has large climatic
swings over the year, i.e. very hot and dry period of almost two and a half months and
a colder period of a shorter duration. The hot dry period is followed by a hot humid,
monsoon period of about two months with intervening periods of milder climate.

3. The site
Located in Faridabad, near New Delhi, this house has been designed and built in the
‘composite climatic context’. The site of about 1000 m2 had a plan area in the ratio of 1:3
with the shorter side facing the road and oriented north
Maximum exposure to south-east for living spaces and buffer spaces on south –west to
eliminate heat gains during summer

4. Planning in response to climate
The demand on building design was to respond to the extremes:
eliminate(minimize) heat gain in hot dry period, maximize ventilation in hot
humid period from zones/areas designed as heat sinks and maximize heat gain
in the cold period. This has been achieved in this house entirely through the
form and fabric of the building. A courtyard facing and opening onto north-cast
has been designed as a heat sink. The entire house form has been developed
around the courtyard with all the main living spaces wrapping around it and
having maximum south-east orientation that is the ideal exposure for this
context A large volume living space designed as a double height space is
wrapped around the courtyard. Butler spaces Like the toilets and stores are
located on the overheated south-western exposure to eliminate heat gain in
summers.

5. Diurnal swings in temperature are attenuated by judicious design and
placement of thermal mass, utilizing local stone as the major material of
construction,
The resultant building provides a comfortable environment with the
temperatures humidity, and airflow levels remaining in the comfort zone
during all seasons of the year.
Double-height living
space for ventilation and
day lighting.

6. • House form developed around
courtyard (acts as heat Sink)
• Large volumes of spaces coupled
with courtyard for ventilation
• Buffer spaces located on the
overheated south- western
exposure
• Form of the building allows
solar penetration according o
seasonal changes
• Pergola and louvers cut off
unwanted radiation
• Local stone used as major
construction material, which
provides thermal mass for
attenuation of diurnal swings in

8. PEDA – Solar Passive Complex,
Chandigarh is a unique and
successful model of Energy Efficient
Solar Building, designed on solar
passive architecture with the partial
financial support of Ministry of New
& Renewable Energy, GOI and Dept.
of Science, Technology, Environment
and Non-conventional Energy, Govt.
of Punjab
Design features
• Floors Interconnected volumetrically to
enable passive space conditioning of the
entire volume of the building
• Large cut-outs for light and ventilation
wells
• Building-integrated solar photovoltaic
and solar water heating
• Winter heating by direct solar gain
through roof glazing and Summer
cooling through wind tower
• Thermal mass of floor slabs moderates
diurnal swings

9. Water bodies with waterfalls
and fountains have been placed
in the central atrium of the
complex for cooling of the
whole complex in the hot and
dry period.

10. The PEDA building is a series of overlapping floors
at different levels in space floating in a large volume
of air, with interpenetrating large vertical cut-outs.
These vertical cut-outs are integrated with light
wells and solar-activated naturally ventilating,
domical structures. This system of floating slabs and
the interpenetrating vertical cutouts is then
enclosed within the envelope of the building. The
envelope attenuates the outside ambient conditions
and the large volume of air is naturally conditioned
by controlling solar access in response to the
climatic swings, i.e. eliminating it during hot-dry
period and maximizing its penetration in cold
period. The large volume of air is cooled during the
hot period by a wind tower, integrated into the
building design, and in the cold period this volume
of air is heated by solar penetration through the roof
glazing, generating a convective loop

11. While thermal performance of the
building is a major parameter of design,
adequate distribution of daylight within
the entire working zone of the building
is a major criterion for design. This has
been achieved through the domical
structures designed above the light
wells, which are evenly distributed
throughout the building.
Solar Power Plant: 25Kwp
building integrated solar
photovoltaic power plant has
been set up to meet the basic
requirement of electricity in the
complex

12. Unique Shell Roofing on Central
Atrium : The Central atrium of the
complex having main entrance,
reception, water bodies, cafeteria and
sitting place for visitors constructed with
hyperbolic shell roof to admit daylight
without glare and heat coupled with
defused lighting through glass to glass
solar panels. The roof is supported with
very light weight space frame structure.

13. Landscape Horticulture: The
space around the building,
inside and outside of boundary
wall and a big lawn in the south
has been designed with trees,
shrubs and grass. The big trees
along the boundary wall acts as
a curtain to minimize air
pollution, sound pollution and
filter/cool the entry of air
Auditorium: A unique
auditorium scientifically
designed to control heat
penetration, light & sound
distribution is placed in the
north under the shade of main
building.
