Green Building

Green Building - also known as sustainable, ecological, environmentally friendly or high performance building - is the practice of:

  1. Increasing the efficiency with which buildings and their sites use and harvest energy, water, and materials; and
  2. Protecting and restoring human health and the environment, throughout the building life-cycle: siting, design, construction, operation, maintenance, renovation and deconstruction.

In other words, a green building is a structure that is environmentally responsible and resource-efficient throughout its life-cycle. These objectives expand and complement the classical building design concerns of economy, utility, durability, and comfort.

Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:

  • Efficiently using energy, water, and other resources
  • Protecting occupant health and improving employee productivity
  • Reducing waste, pollution and environment degradation

For example, green buildings may incorporate sustainable materials in their construction (e.g., reused, recycled-content, or made from renewable resources); create healthy indoor environments with minimal pollutants (e.g., reduced product emissions); and/or feature landscaping that reduces water usage (e.g., by using native plants that survive without extra watering). 

Buildings have an enormous impact on the environment, human health, and the economy. The successful adoption of green building strategies can maximize both the economic and environmental performance of buildings.

There are three primary rating systems in India: GRIHA, IGBC and BEE.

GRIHA stands for "Green Rating for Integrated Habitat Assessment" and has been developed keeping in mind the various conditions and requirements specific to the design and construction of green buildings in India.

IGBC stands for "Indian Green Building Council" and provides the LEED (Leadership in Energy and Environmental Design) ratings for green buildings devised in the United States in India.

The Bureau of Energy Efficiency (BEE) launched a Star Rating Programme in 2009, for office buildings in order to accelerate the Energy Efficiency activities in commercial buildings. The programme developed by the Bureau of Energy Efficiency, BEE is based on actual performance of the building, in terms of specific energy usage (in kWh/sq m/year).
