Manmohan Singh, Prime Minister of India dedicated to the Nation “Indira
Paryavaran Bhawan” in the presence of Dr M. Veerappa Moily , Minister for
Environment & Forests and Shri Jairam Ramesh
Minister for Rural Development here today .
The centrally air conditioned office building which has provision to accommodate
about 600 officials of the Ministry of Environment and Forests is located on
Jorbagh Road and in proximity to other Central Government
Paryavaran Bhawan is India’s first on site Net Zero Building built by
adoption of solar passive design and energy efficient building material. This
building is expected to be a trend setter in the country and shall inspire
people towards adoption of green technology.
building has been designed as the highest green rated building, i.e., GRIHA
5-Star and LEED India Platinum. The requirements of GRIHA 5-Star
and LEEDS Platinum ratings have been achieved by adopting various measures some
of which are as follows:
Ventilation has been achieved by orientating the building in an East-West
direction, separating different blocks with connecting corridors and having a
large central court yard.
design is such that 75% of natural daylight is utilised to reduce energy
entire building has an access friendly design for differently-abled persons.
With an Installed capacity of 930 KW peak power, the building has
the largest roof top Solar system among Multi storied buildings in India.
energy savings of about 40% has been achieved by
adoption of energy Efficient Chilled Beam system of Air Conditioning. This
is an innovative air conditioning system, where air conditioning is done by
convection currents rather than air flow through diffusers and chilled water is
circulated right up to the diffuser points unlike the conventional systems.
materials have been used like Fly ash bricks, regional building materials,
materials with high recycled content, high reflectance terrace tiles and rock
wool Insulation of outer walls.
renewable Bamboo Jute Composite material has been used for door frames &
windows, with hermetically sealed double glass. Calcium Silicate ceiling tiles
having high recycled content andgrass paver blocks in pavements and roads.
in water consumption has been achieved by use of Low discharge water fixtures,
recycling of waste water through Sewage Treatment Plant, use of plants with Low
water demand in landscaping, use of Geothermal cooling for HVAC system, rain
water harvesting and use of curing compounds during construction.
The cost of
the project is about Rs. 209 crore including the cost of land, solar photo
voltaic power generation and its evacuation system, three level mechanized
basement parking system, air-conditioning system supported by geo-thermal
cooling, IT services, audio and video system in auditoriums & committee
rooms, furniture, provision for horticulture and other services. The building
has an earthquake resistant structure with a total plinth area of 31,488sqm.
The building covers only 30% of the plot area. More than 50% area, outside the
building, is a soft area with plantation and grassing. Even circulation roads
and pathways are a soft area to enable ground water recharge.
parking system in the basement can accommodate 330 cars. Provisions have been
made for a cafeteria roof garden, as well as a gymnasium and yoga room for
recreation and wellness of the employees. The office has been furnished with
modular furniture & work stations. Thin client networking system has been
provided instead of conventional desktop computers to minimise energy
consumption. A Solar power generation system has been provided at terrace
level, by creating 6000sqm support area, for meeting with the complete power
demand of the building. Power generation has already started w.e.f. 19.11.2013 which is being fed to the NDMC grid.
Paryavaran Bhavan building has already received the following awards.
2013: The Project received an award
from Adarsh/GRIHA of MNRE for exemplary demonstration of Integration of Renewable Energy Technologies
2014: The Project was accorded 5-Star Green Building Certification by
GRIHA under MNRE
