Guidelines for Implementation of Energy efficient
solar/ green building Programme
Background
Energy efficient solar buildings are constructed based on the techniques of solar
passive design with a view to provide comfortable living and working conditions, both
in winter and in summer. These buildings can be integrated with renewable energy and
energy conservation devices and systems and can save over 30 to 40 % of conventional
energy that is used for lighting, cooling or heating. Such buildings have been tried out
in a few States as a result of the initiatives taken by the Ministry. Finding the concept
of solar buildings useful, the state governments of Himachal Pradesh, Punjab, Haryana
and Nagaland have already made it mandatory to construct all new buildings in
government & public sectors on this concept. Necessary G.O.s have been issued and
the development authorities have been asked to approve building plans for construction
only if the designs incorporating solar passive features are certified by approved
architects or the experts. Over 40 experts/architects are presently involved in the
country in practicing energy efficient solar buildings. Bureau of Energy Efficiency
(BEE) have recently introduced Energy Conservation Building Code (ECBC) which
includes energy efficient design features. National Building Codes have also been
developed by the Bureau of Indian Standards (BIS) which incorporates some of the
concepts of energy efficient solar buildings. Sufficient literature/ publications are also
available for design of such buildings.
Efforts are now being made to construct Green Buildings all over the country
which not only take care of energy conservation but also look into water and waste
management, environmental impact, minimum destruction of natural resources and
various other aspects in an integrated way. Building Rating Systems have been quite
effective in raising awareness and popularizing energy efficient and green building
design. Most of the internationally devised rating systems have been tailored to suit the
building sector of the country where they were developed. In India, a US based LEED
(Leadership in Energy and Environmental Design) Rating System is under promotion
by CII-Godrej Green Business Center (GBC) which is more on energy efficiency
measures in AC Buildings. A couple of other Rating systems suitable for Indian
conditions e.g. TERI-GRIHA and Eco-Housing System have also been developed by
TERI and Pune Municipal Corporation respectively and are under promotion in the
country.
Keeping in view our climatic conditions, and in particular the construction of
non-AC buildings, a National Rating System – GRIHA (Details available at MNRE
website: www.mnre.gov.in) has been developed which is suitable for all types of
buildings in different climatic zones of the country. The Rating System was initially
conceived and developed by The Energy & Resources Institute, TERI. It has been
modified as a National Rating System after incorporating various suggestions by a
group of architects and experts. It takes into account the provisions of the National
Building Code 2005, the Energy Conservation Building Code 2007 and other IS codes,
local bye-laws, etc. Through various qualitative and quantitative assessment criteria,
GRIHA would be able to ‘rate’ a building on the degree of its ‘greenness’. It will
operate on a 100 point marking system with 70 to 80 points to be obtained for 3 star
rated buildings and 81-90 points for 4 star rated buildings. The rating would be applied
to different types of new and existing buildings, whether commercial, institutional or
residential.
