Energy Conservation Building Code (ECBC-Commercial) 2007

The Energy Conservation Building Code (ECBC) was developed by the Govt. of India for new commercial buildings and released on 27th May 2007. ECBC sets minimum energy standards for commercial buildings having a connected load of 100kW or contract demand of 120 KVA and above. While the Central Government has powers under the EC Act 2001, the state governments have the flexibility to modify the code to suit local or regional needs and notify them. Presently, the code is in voluntary phase of implementation. About 22 states are at various stages of mandating ECBC, wherein most of building construction activities are happening across the country.
