Energy Conservation Building Code for Residential Buildings

Last updated: 1 July 2020

The Eco Niwas Samhita, Part – I Building Envelope (Energy Conservation Building Code for Residential Sector) is developed and launched on 14th December, 2018. It sets minimum building envelope performance standards to limit heat gains (for cooling dominated climates) and to limit heat loss (for heating dominated climate) as well as for ensuring adequate natural ventilation and day lighting. The code is applicable to all residential use building projects built on plot area = 500 m2. The code has been developed with special consideration for its adoption by the Urban Local Bodies (ULBs) into building byelaws.  Last year, the government launched Eco-Niwas Samhita 2018 (link is external), which is the ECBC for residential buildings, to push for energy efficiency in the residential sector. The code aims for promoting design and construction of homes including apartments and townships to give the benefits of energy efficiency to the occupants.

In the subsequent years, new components will be added to the Eco-Niwas Samhita in the Part-II, which will address other aspects such as, Energy Efficiency in Electro-Mechanical Equipment for Building Operation, Renewable Energy Generation, Embodied Energy of Walling Materials and Structural Systems.

States need to adopt for code to come into force
