What is a green building? What is the meaning of green building rating and designing system?

Answer by A Quora admin:

A green building refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building’s life-cycle from siting to design, construction, operation, maintenance, renovation, and deconstruction.
It is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building. Buildings across the world have a tremendous environmental impact during their life. Globally, buildings are responsible for at least 40% of energy use. Construction of new buildings generate large amount of solid waste and in turn, disturb natural habitat & vegetation.
Green buildings offer immense potential to reduce consumption & regenerate resources from waste and renewable sources
A green building rating system is an evaluation tool that measures environmental performance of a building through its life cycle. It usually comprises of a set of criteria covering various parameters related to design, construction and operation of a green building. Rating programmes would help to address all aspects related to environment and are an effective tool to measure the performance of the building / project.

Two rating systems are followed in India:
·  LEED India (Leadership in Energy & Environmental Design) by Indian Green Building Council (IGBC)
GRIHA – (Green Rating for Integrated Habitat Assessment) by TERI  – National Rating System

LEED
The Leadership in Energy and Environmental Design (LEED-INDIA) Green Building Rating System is a nationally and internationally accepted benchmark for the design, construction and operation of high performance green buildings.
LEED-INDIA promotes a whole-building approach to sustainability by recognizing performance in the following five key areas:

·        Sustainable site development
·        Water savings
·        Energy efficiency
·        Materials selection and
·        Indoor environmental quality

GRIHA

GRIHA, an acronym for Green Rating for Integrated Habitat Assessment, is the National Rating System of India. It has been conceived by TERI and developed jointly with the Ministry of New and Renewable Energy, Government of India. It is a green building ‘design evaluation system’, and is suitable for all kinds of buildings in different climatic zones of the country.
The rating applies to new building stock – Commercial, Institutional and Residential types of varied functions. It is endorsed by the Ministry of New and Renewable Energy, Government of India as of November 7, 2007.
