Introduction of Green Rating for Integrated Habitat Assessment - GRIHA
GRIHA is an acronym for Green Rating for Integrated Habitat Assessment. GRIHA is a Sanskrit word meaning - "Abode". GRIHA attempts to minimize a buildings resource consumption, waste generation, and overall ecological impact to within certain nationally acceptable limits / benchmarks. It is a ratification tool which helps the construction industry to reduce the harmful effects of construction on the environment thereby promoting sustainable development.
GRIHA 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. GRIHA was adopted as the National Rating System for Green Buildings in India by MNRE in 2007.
The GRIHA (Green Rating for Integrated Habitat Assessment) rating is based on the points obtained against various criteria (mandatory as well optional) laid down under respective latest GRIHA Manuals.
First Green building In India
Our first major milestone came in 2003 when the CII-Godrej GBC building in Hyderabad became Indias first platinum-rated green building. It was the greenest building at that point in time and this distinction really marked the start of the green building movement in India.
