GREEN RATING MUST FOR GOVERNMENT BUILDINGS

 In a landmark decision, the Union government has made it mandatory for all new buildings of the public sector undertakings and the government to seek new green rating norms in an effort to ensure energy efficiency and tackle climate change threats.  Under the GRIHA scheme, buildings would be rated by technical expertise from TERI, which is headed by R.K. Pachauri. The aim of a green building design was to minimise the demand for non-renewable sources and maximise its utilisation.  GRIHA The national rating system for green buildings in India, GRIHA has been developed and operationalized by
TERI  The Energy and Resources Institute, commonly known as TERI (formerly Tata Energy Research Institute), established in 1974, is a research institute based in New Delhi focusing its research activities in the fields of energy, environment and sustainable development.  TERI is an independent, not-for-profit, research institute focused on energy, environment and sustainable development, devoted to efficient and sustainable use of natural resources. 
The origins of TERI lie in Mithapur, a remote town in Gujarat, where a TATA engineer, Darbari Seth, was concerned about the enormous quantities of energy his factory spent on desalination. He proposed the idea of a research institute to tackle the depletion of natural resources and energy scarcity. J. R. D. Tata, chairman of the TATA Group, liked the idea and accepted the proposal. TERI was setup with a modest corpus of 35 million rupees. On the invitation of the then Prime Minister Indira Gandhi, TERI registered in Delhi in 1974 as the Tata Energy Research Institute. As the scope of its activities widened over a period of time, it was renamed The Energy and Resources Institute in 2003. TERI. GRIHA is an acronym for Green Rating for Integrated Habitat Assessment. It was conceived by TERI and developed jointly with the Ministry of New and Renewable Energy to the Indian Government. It is a green building design evaluation system and is suitable for all kinds of buildings in different climatic zones of the country.

 The Institute's Director General Rajendra K. Pachauri is also the chairman of the 2007 Nobel Prize awarded Intergovernmental Panel on Climate Change. TERI's Executive Director is Dr Leena Srivastava.
