Residential : Eco-Niwas Samhita (ENS)

Introduction to Eco-Niwas Samhita (EMS)


The Residential Energy Conservation Building Code, or Eco Niwas Samhita (ENS), has been developed by BEE to set standards to limit heat gain and loss and ensure adequate natural ventilation and daylighting potential. Eco Niwas Samhita, Part – I Building Envelope (Energy Conservation Building Code for Residential Sector) is developed and launched on 14th December 2018 on the occasion of National Energy Conservation Day by Hon’ble speaker of Lok Sabha and Hon’ble Minister of Power, New & Renewable Energy. It been developed to set 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.


Eco-Niwas Samhita (ENS) launched in two parts where ENS 2018 (Part 1) sets minimum standards for building envelope designs for energy-efficient residential buildings.

Eco-Niwas Samhita 2021 (ENS) Part 2 of the code launched by the Bureau as ENS 2021 focuses on the building’s code compliance and electromechanical systems. 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.

Eco-Niwas Samhita (ENS) applies to

  • “Residential buildings” with plot area ≥ 500m2 and
  •  “Residential part of Mixed-land use building projects with plot area ≥ 500m2.

Energy Efficiency Label for Residential Buildings


“Energy Efficiency Label for Residential Buildings” launched by Hon’ble Minister of State (IC) for Power and Renewable during the conference of Ministers for Power, New & Renewable Energy of States & Union Territories held at Gurugram, Haryana on 26th February 2019.

The key objective of the programme is to make a transparent instrument over the energy performance of a home which will gradually lead to an effective model taken into consideration while deciding over the home prices in future. The objective of the labeling program is to make an energy performance of a home an instrument of comparison while deciding over the home prices in the future. It also aims to provide a benchmark to compare one house over the other on the energy efficiency standards to create a consumer-driven market transformation solution for energy efficiency in the housing sector.

This program is another step towards realizing the vision of an energy surplus India with 24*7 power to all. Proposed Labelling program will cover all types of residential buildings in India. All the envisaged objectives can be achieved through the proposed labeling mechanism by making it as a mandatory information required in any real estate transaction/leasing.
