11.  Land Area : 3116 sqm
 Built Area : 3096 sqm superstructure
: 1526 sqm basement
 Population : 300 persons
 Functions : Offices , Resource Centres ,
Conference Facilities

12.  The Development Alternatives World
Headquarters, located in New Delhi, is one of
the first buildings in India that aims at Zero
Emissions.
 The building is best described as a living
ecosystem: as fine balance of natural and
man-made processes employing environment-
friendly energy, material and water
management methods
 Nearly all interior and exterior walls are built
of cement-stabilized compressed-earth block
and cement-stabilized fly-ash lime gypsum
block, the manufacture of which recycles
plentiful local materials in processes that use
local labor and low energy.

13.  The building uses predominantly natural,
recycled, renewable, and reusable materials
embodying low process energy. Highly energy
intensive materials like aluminum are
shunned; others, such as glass and steel, are
used frugally.
 All rainwater that falls on the site is used to
recharge the groundwater. All wastewater is
recycled, treated on site and used for
irrigation and flushing toilets.

16.  The ground floor and the outdoor areas of
Development Alternatives world
headquarters are open to the public, inviting
public participation in the programs and
activities of the organization. The entire
building is barrier-free.
 Operating cost is kept low by natural lighting
of all workspaces and a flexible and efficient
hybrid cooling system.
 The project illustrates traditional,
environmentally efficient construction
materials and systems that can be
economically developed for low-energy mass
production and adopted by the mainstream
building industry, especially in developing
countries.

23. The Institute of Rural Research And Development (IRRAD) houses the
headquarters for the Non-profit Government Organization, S.M. Sehgal
Foundation (SMSF) which works on development projects in rural
Haryana.

24.  This is the first office building in which the earth
that came out from the basement excavation has
been used as compressed stabilized earth block
in the masonry of the building, and in making its
landscape garden slopes
 This is the first office building in gurgoan that is
designed to minimize the ecological foot print
and carbon dioxide emissions due to the type of
material used.
 For instance wood is used instead of aluminum
for doors and windows and the use of burnt brick
is minimized. No imported stones are used.
 This gives about 30 percent reduction in CO2
emissions compared to the kind of buildings that
are generally prevalent today.

25.  Category : Office Building
 Area : 5112 SQ.M
 Cost : 17 Cr.
 Owner : Institute of Rural Research And
Development
 Period of Project : 32 month(s)
 Structure Type : RCC (Reinforced Cement
Concrete)
 Materials Used : Natural Stone
 Climate : Moderate
 Topography : Plain Land
 Concept : Sustainable Building
 Form of project : Rectangular
 Spatial configuration : Linear

26.  The rainwater from the roof is collected to fulfill the
water requirement for an efficient water cooling
based air-conditioning system.
 Internal courtyards provide daylight and ventilation
thereby reducing the load on artificial lighting and
mechanical ventilation systems.
 . There is provision for using recycled water for
irrigation and flushing toilets where water efficient
appliances are used
 The aesthetic quality of the building is derived from
the principles of sustainable design – the use of
natural materials, minimal use of glass, interesting
shading device and integration of sheltered courtyard
spaces makes for its unique beauty and comfort as
well as the graceful feel.
 Special feature of the building is deriving beauty
from waste. The entrance lobby, boardroom and the
central atrium use waste plywood crating planks,
broken tiles and glass to demonstrate how waste can
be converted into a beautiful resource.

27. Shading
devices

28.  The building has North-South orientation,
minimal glass area, good window shading and
good insulated wall and Roof.
 The project is designed with Radiant Cooling
technology for air conditioning.
 Radiant cooling reduces air requirement
substantially and thus reducing operational
costs.
 The system also delivers fresh air in an
occupied zone as against supplying it from
top.
 The building is cooled in night time making
structure as a thermal storage.
 All these measures makes the building highly
energy efficient and monthly energy savings
are 35% to 40% lower

29.  Highly reflective roof - floor made of
exterior paving material – minimize heat
absorption
 Reflective glass is used in the inner atrium to
increase the light in working space
 Light fittings in general services – movement
activated sensors
