Rapid increase in residential building stock, coupled with increase in electricity use for space conditioning, is resulting in rapid increase in electricity use in residential buildings. Projection done by NITI Aayog indicates that the electricity consumption for the residential sector is expected to increase 6-13 times by 2047. Data collected from a sample of urban middle-income apartments shows that electricity for providing thermal comfort contribute to 30- 60% of the annual electricity consumption. Another important aspect is thermal comfort, which is of utmost importance in all kinds of housing, but more so in case of affordable housing, so as to ensure health and well-being of the occupants. BEE envisaged a phased approach for the development of the residential building energy conservation code. Making houses energy efficient is certainly a way of avoiding a long term futile electricity consumption liability in residential buildings.

Eco-Niwas Samhita 2018 (Part-I)

Thus, the 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. 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, 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.

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.
