3. HOT AND DRY CLIMATE
The region of hot and dry climate in India
4. FEATURES OF CLIMATE
Summer Midday high-40 to 45° C
Summer night low - 20 to 30⁰ C
Winter Midday high - 5 to 25° C
Winter night low - 0 to 10° C
Diurnal variation - 15 to 20 deg C - 15 to 20 deg
Humidity-Very low - 25 to 40%
Precipitation - Low-Less than 500 mm per year
Sky condition - Cloudless sky with high solar radiation causing glare
5. FLORA AND FAUNA
In hot and dry climate mostly throny
bushes are found. In rajasthan region
their is cactus, babhhol and khajur,etc.
Gujrat and Madhyapradesh has a
eucalyptus,teak and khair. In central
Maharashtra their is Babhool,Peepal
6. FLORA AND FAUNA
Camel is commenly used animal found
in Rajasthan Desert along this chinkara,
Python molurus also fauna of Rajasthan.
Asiatic Lion is rare animal of Gujrat. In
central maharshtra their is Gawa,
Neelgai and some rare magratory birds.
7. DESIGNING FOR HOT &
The orientation of the building should help
in minimizing sun exposure during summer
and provide warmth during winter, for
which the longer walls of the buildings
should face the North and South and avoid
8. DESIGNING FOR HOT &
SMALL WINDOW OPENINGS
As much as it is vital to provide ventilation it is
also necessary to keep the size of the windows
small and minimal in number as to reduce
heat when designing in a hot and dry climate.
One of the examples of this feature would be
the traditional Bungha house.
9. DESIGNING FOR HOT &
THICK AND HIGH EXTERIOR WALLS :
Another great feature to be used in these regions is
the usage of thick and high walls with insulation. Two
sides of concrete walls with the insulation material in
the middle is a smart solution to both temperature-
related issues as it helps in keeping the interiors cool
during summer and warm during winter.
10. DESIGNING FOR HOT &
Roofs suffer the most direct contact with the sun
receiving solar radiation throughout the year. Hence
Roofs become an essential element to consider while
designing for a hot and dry climate. A double roof or
single white roof is preferred as they reflect heat to
the maximum extent along with a damp roof.
Features like a terrace garden or a roof pool may
also come in handy while battling this predicament.
11. DESIGNING FOR HOT &
PLANTS AND VEGETATION
Plants act as a cooling element in the regions of the
hot and dry climate, and that is why vegetation plays
a key role. They help in the purification of air along
with increasing the humidity. They are placed in and
around the building, preferably in the facade, terrace,
or courtyard, providing natural shade and
maintaining a lower temperature during the summer.
12. DESIGNING FOR HOT &
Colors that absorb less heat should be used to
paint the external surface. Darker shades
should be avoided for surfaces exposed to
direct solar radiation. White walls are preferred
in the exteriors as they reflect heat, given their
high reflection ratio. Cool colors are chosen in
interiors for their adaptability to temperatures.
13. DESIGNING FOR HOT &
SHADING DEVICES/ ELEMENTS
While designing in a hot and dry climate, it is
important to place shading devices to prevent
the excessive heat directly penetrating the
facade. Devices like visors can be provided on
the roof, offering protection to the facade from
extreme radiations and thus maintaining a
comfortable temperature in the interiors.
14. DESIGNING FOR HOT &
BALCONIES/ COURTYARDS / VERANDAHS
These spaces help in cross ventilation and,
when covered with pergola and plants, can act
as cooling systems helping in reducing the
temperature of the interiors when connected.
