ECBC – Status of adoption by States
Section 15 – Powers of State Government
Amend ECBC to suit regional and local climatic conditions andmay, by rules made by it specify and notify ECBC with respect touse of energy in the buildings.
Section 18 – Power of Central Government or State Government
Central Government or State Government may issue directives forefficient use of energy and its conservation
Ministry of Power, India 10
States have used the powers under EC Act to notify/ issue directives for ECBC
Notification can also be done through amendments in local (municipal) building bye-laws
Energy Conservation Building Code
ECBC
minimum energy efficiency standards
Applicable to large commercial buildings
(connected load of 100 kW/contract demand of 120 kVA and above)
ECBC prescribes standards for:
Building Envelope (Walls, Roofs, Windows)
Lighting (Indoor and Outdoor)
Heating Ventilation and Air Conditioning (HVAC) System
Solar Hot Water Heating
Electrical Systems
Ministry of Power, India 11
While ECBC developed at Central level by BEE, its enforcement lies withthe StatesMinistry of Urban Development developed generic building bye-laws andadvisory circulated to include in bye-laws
