How Green is your Property?

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.

Points achieved          GRIHA ratings

            50-60                         1 star 

            61-70                         2 stars

            71-80                         3 stars

            81-90                         4 stars

            91-100                      5 stars

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.
