The housing sector in India is growing at a rapid pace and contributing immensely to the growth of the economy. This augurs well for the country and now there is an imminent need to introduce green concepts and techniques in this sector, which can aid growth in a sustainable manner. Green concepts and techniques in the residential sector can help address national issues like handling of consumer waste, water efficiency, reduction in fossil fuel, use in commuting, energy efficiency and conserving natural resources. Most importantly, these concepts can enhance occupant health, happiness and well-being.
The objective of Green Homes is to facilitate the creation of energy efficient, water efficient, healthy, comfortable and environmentally friendly houses.
The residential sector is a large consumer of electrical energy. Green Homes can reduce energy consumption through energy efficient lighting, air conditioning systems, motors, pumps, etc., the rating system encourages green homes, which select and use BEE labelled equipment and appliances. The energy savings that can be realized by adopting this rating programme can be to the tune of 20 – 30%.
Fossil fuel is a slowly depleting resource, world over. The use of fossil fuel for transportation has been a major source of pollution. The rating system encourages the use of alternate fuels for transportation and captive power generation.
The rating system encourages projects to use recycled and reused material and discourages the use of virgin wood thereby, addressing environmental impacts associated with extraction and processing of virgin materials. Reduced usage of virgin wood is also encouraged.
Health and well-being of occupants is the most important aspect of Green Homes. IGBC Green Homes Rating System ensures minimum performance of day lighting and ventilation aspects, which are critical in a home. The rating system recognizes measures to minimise the indoor air pollutants.
Potted plants will not be considered as landscape.
To minimise indoor water usage by installing efficient water fixtures.

* At a flowing water pressure of 3 bar
Landscape to be designed to ensure minimum consumption of water. Ensure that atleast 25% of the landscaped area is planted with drought tolerant species.
To avoid the use of such refrigerants and ozone layer depleting gases which will negatively impact the environment.
Optimise energy efficiency of the building to reduce environmental impacts from excessive energy use.
To encourage the use of energy efficient appliances to reduce energy consumption in the proposed building.
To encourage use of solar energy for water heating applications in the building.
To encourage use of energy efficient lighting systems to reduce energy consumption within the home.
To facilitate segregation of waste at source to prevent such waste being sent to landfills.
Allocate suitable site for sorting out dry and wet wastes. Examine the scope for recycling items of waste collected from building debris and residential wastes. Locate local dealers of waste material such as glass, plastic, paper, newspaper, cardboard, organic wastes and 'e' wastes & batteries.
Encourage the use of building materials available locally thereby minimising the associated environmental impacts. Ensure atleast 50% of the total building materials by cost used in the building should have been manufactured within a radius of 500 Km.
