Commercial : Energy Conservation Building Code (ECBC)

Introduction to Energy Conservation Building Code (ECBC)


The Energy Conservation Building Code (ECBC), was developed by the Bureau of Energy Efficiency (BEE) and is mandated by the Energy Conservation Act 2001, passed by the Indian parliament in September 2001. It was launched on June 28, 2007, was revised in 2017.


ECBC 2017 (Energy Conservation Building Code) was launched by Hon’ble Minister (IC) for Coal, Mines, NRE and Power on 19th June 2017 at Delhi and is applicable for upcoming large commercial buildings with connected load of 100 kW and above or 120 kVA and above. ECBC sets minimum energy standards for commercial buildings such that it does not constrain the building function, comfort, health, or the productivity of the occupants and has appropriate regard for economic considerations (life cycle cost i.e., construction and energy cost are minimized). 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.


ECBC takes into consideration the climatic region of the country, where the building is located. Norms have been developed to cater to 5 different climatic zones in India such as composite, hot and dry, warm and humid, temperate, and cold.


ECBC focuses on building envelope, mechanical systems and equipment including heating, ventilating, and air conditioning (HVAC) system, interior and exterior lighting systems, electrical system and renewable energy.

Further, ECBC 2017 encourages additional improvements in building energy performance. As per ECBC 2017, a new building can achieve higher grades like ECBC or Super ECBC status if these buildings can demonstrate energy savings as per the code.



Objective of Energy Conservation Building Code




Notification of Jharkhand Energy Conservation Building Code (JECBC) 2022


Jharkhand Renewable Energy Development Agency (JREDA) is the State Designated Agency (SDA) to implement the EC Act in the state of Jharkhand. Jharkhand falls into two climatic zones, which are Composite and Warm and Humid. Considering the climatic condition, the ECBC has been amended for the state of Jharkhand. Since the ECBC Code and Rules have been notified in Jharkhand on 7th July 2022, it is mandatory for upcoming commercial buildings that have a connected load of 100 kW or more or a contract demand of 120 kVA or more.


For awareness purposes and to create a pool of energy experts/professionals, JREDA conducts regular training programs in various districts of the state, both through offline and online mode.

Energy Performance Index


The Energy Performance Index (EPI) is a benchmark to measure the energy performance of a building. It is total energy consumed in a building over a year divided by total built up area in kWh/sqm/year.



Star Rating Program for buildings


Star Rating Program for buildings which is based on the energy usage in the building over its area expressed in kWh/sqm/year. This program rates buildings on 1-5 scale, with 5 star labelled buildings being most efficient. Star Labels for day use office buildings, BPOs, Hospitals and shopping malls have been developed.
