SANGATH IS THE OFFICE BUILDING OF THE WORLD FAMOUS ARCHITECT AND THE 2018 PRITZKER PRIZE WINNER, AR.B. V. DOSHI. SANGATH IS THE COLLABORATION OF THE IDEAS AND PHILOSOPHY OF ARCHITECTURE OF THE ARCHITECT BALAKRISHNA V. DOSHI.

1. AN EMBLEMOF DOSHI
PHILOSOPHY
SAGAR PANCHAL

2.  LOCATION:THALTEJ ROAD, AHEMDABAD
 ARCHITECT:BV.DOSHI
 SITE AREA:2346 SQ M
 TOTAL BUILT UP AREA:584SQ M
 PERIOD OF CONSTRUCTION:1979-1981
SANGATH means “moving together with participation”. SANGATH is an
Architects office which is supported by passive solar ventilation
technique.
The design concerns of climate (temprature , humidity, air flow etc.). And
the use of special material made the building cost effective and fiesable
for passive design.

5. HOT AND DRY
 In ahemdabad,the summer temperature reaches 45 degree celcius and
the heat is very intense.It is the heat rather than the breeze that
becomes critical
 Natural comfort can be achieved by protecting spaces from the heat and
glare of sun

6.  Design concerns of climate (temperature,humidiy,strength)
 Extensive use of vault
 Main studio partly below the ground(sunken)
 The building is raised on a plinth and burried in the ground
 Very less use of mechanical instrument
 Special materials are used resulting in a low cost building costing it
 Lot of vegetation and water bodies
 Continuity of spaces
 Use of lot of difuse sunlight
 Complete passive design

7.  This structure is closely integrated
With outdoor spaces
 The west and the south facade is
Shaded by dense trees
 Wind flows from west and south
West side so as to create a central open
Space through which the wind can
Flow unobstructed
 The site is quadrangle looking
South over a road
 Extensive use of vaults.
 Grassy steps used as informal amphitheater.
 Use lot of diffused light.
 Lot of vegetation and water bodies.

8.  SANGATH was constructed with
Hollow clay tiles embeded in the wall
 The outer skin is covered with
Tiles fragmented pieces of waste
Material from the manufacturer
 The hollow interior spaces
Are isolated by clay within the structure
 The suns heat is reduced and reflected
by the white mosaics that cover the
each vault
 The facades are covered with tiles or
cement and plaster
 The vaults are primary architectural
features made of sandwich layer of
ferro cement and ceramic fuses.

9. STACKVENTILATION
 Ventilating window at upper volume
releases the accumulated hot air through
pressure difference
 Doshi use this traditional technique not
only to reduce the heat inside the
building but also as an important
element of the methodology in the use
of waste material.

10.  The building measures have ensured excellent climate contol in terms of
keeping the inside cool and increasing the time-lag for heat transfer.
 There is a difference of about 8 degree celcious between the interior and
exterior roof skin tempratures.The time lag of transfer is nearly 6 hours.
 The natural elements are harmoniously blended with built environment,
and waste material refuse have ensured cost economy as well as
environmental consiousness.
