Bureau of Energy Efficiency (BEE) is an Autonomous Body under the Ministry of Energy, Government of India. Its role is to assist the Nation in Developing Policies and Strategies with a thrust on self-regulation and market principles, with the primary objective of Reducing Energy Intensity of the Indian Economy.
BEE Star Rating for Buildings is a unique tool, which is developed to assess the status of Energy Efficiency in Commercial Buildings. This tool is a Ready Reckoner to determine the Energy Efficiency. This rating system is applicable to buildings with the connected load of 100 kW or greater or contract demand of 120 kVA or greater.
Under this system of evaluation, 1-5 stars are awarded based on the buildings energy usage. The Highest Rating i.e. Five Star Rating is recognised as Highest State of Efficiency. The rating is based upon different criteria such as built-up area, conditioned and non-conditioned areas, type of building, hours of operation of building in a day, climatic zone and other miscellaneous information related to facility.
