With the population in India rising drastically from time to time, and the
urbanization also rising up, there is a radical growth in power consumption. It
has become very necessary to conserve power and energy, due to which
eco-friendly or 'green' buildings are coming up in various parts of the
country. At present, India has around 267 certified green buildings, and the
government is supporting the plan of more eco-friendly buildings to be built up
in the country.

How Green Is Your Property |
A green building is one that conserves natural resources by using less
water and reducing the use of plastic and waste material. It reduces water
consumption by 30-70% and energy consumption by 30-50%. Green projects include
water treatment and waste treatment plants, rain water harvesting system, solar
air-conditioning, solar heating, good ventilation and strategically planted
trees. Hence, they optimize energy efficiency, generate less waste and provide
healthy spaces.
These days, there are many builders who tag their buildings as 'green' only
because they provide landscape gardens or lawns. But, this is not right. In
order to tag your property as eco-friendly or green, you need to have specific
certifications by certain committees assigned for the duty like Indian Green
Building Council (IGBC), Bureau of Energy Efficiency (BEE) and Green Rating for
Integrated Habitat Assessment (GRIHA), who give certifications or ratings based
on parameters like design, construction materials, ventilation, lighting, water
management, waste management and energy efficiency. Let us see how.
Indian Green Building Council (IGBC)
The IGBC has rating programmes for both residential as well as commercial
buildings. For residential properties, it gives ratings based on the following
categories.
·
Site Preservation &
Restoration
·
Site Planning & Design
·
Water Efficiency
·
Energy Efficiency
·
Materials & Resources
·
Innovation & Design
Process
For commercial or factory properties, the following categories are considered.
·
Soil erosion control
measures in future
·
Changes in design to
accommodate requirements like lifts, rest rooms, etc.
·
Change to low flow water
fixtures
·
Rainwater harvesting
·
Limit turf areas
·
Policy for use of green
materials in future
·
Minimum fresh air
ventilation
·
Comfort conditions
·
Eco-friendly housekeeping
materials
Here is a summary of how IGBC rates residential and commercial properties.

Bureau of Energy Efficiency (BEE)
The BEE is an agency that was created in March 2002 under the provisions of
India's 2001 Energy Conservation Act. It has been created to develop programs
which will increase the conservation and efficient use of energy in India. As
far as properties are concerned, it is applicable for those buildings that have
a connected load of 100 KW or more. The ratings are done on a 1 to 5 star
scale, with 5 star labelled buildings being the most efficient. This rating is
applicable only for a period of 5 years from the date of issue. The ratings are
done based on the use of the building, hours of operation, climatic zone and
the space.
Green Rating for Integrated Habitat Assessment (GRIHA)
GRIHA is conceived by the Center for Research on Sustainable Building
Science (CRSBS), TERI (The Energy and Resources Institute, New Delhi) and
developed jointly with the Ministry of New and Renewable Energy (MNRE). It is
currently operating under ADARSH (Association for Development and Research on
Sustainable Habitats) and is supported by the National Advisory Council (NAC)
and Technical Advisory Committee (TAC). The GRIHA certification is eligible for
buidlings that are spread over 2500 square meters or more. GRIHA rates the
buildings from 1 to 5 stars, based on 34 parameters, which are divided into
four groups, that are -
·
Site selection and site
planning
·
Building planning and
construction
·
Building operation and
maintenance
·
Innovation
Let us see how buildings are rated by GRIHA.

Now that you know quite a bit about certifications of green buildings, when
you think of purchasing one, do ask for the right certification from the
builder or owner of the property and then decide on how eco-friendly the
property is. One of the best green projects in Bangalore is the AdiseshGreen City, which is spread over 60 acres of land and is built in a
non-pollution zone of Narasapura, with a wide range of amenities including
water treatment plants, sewage treatment plants and rain water harvesting. You
can also check for other properties by Adisesh Projects around this beautiful
area like villas in Hoskote, Malur and Devanahalli.
