“Presently, residential buildings account for 24% of the total energy consumption in India, which will rapidly increase without any intervention. Therefore, the need of the hour is to leverage the ENS, part I and II, and ensure it is implemented effectively.”
ENS was launched in two parts. Part I sets minimum building envelope performance standards to limit heat transfer, enhance natural ventilation, and capture daylight potential. Part II focuses on energy-efficient electromechanical equipment for building operation such as air conditioners, fans and lighting fixtures; and renewable energy.
“If ENS (Part 1) is implemented effectively, it offers an energy-saving potential of 125 billion units of electricity per year by 2030 (the baseline year 2018),” Mr Nagar said.
“This is equivalent to about 100 million tons of CO2 emission.”
With relevant policies already in place at a Central government level, the goal of the project was to support Indian State governments to adopt appropriate sustainable buildings policies and energy codes. GBPN collaborated with Alliance for an Energy-Efficient Economy (AEEE), which works to increase ENS adoption in India through its policy adoption fund.
Starting in 2020, the project was conducted in three phases:
- Inception: The inception phase assessed the policy landscape at the National, State and city/local level to kick-start the work towards implementation of ENS, working in collaboration with the ongoing programs administrative process at the Central and State level. The Ahmedabad Municipal Corporation (AMC) in the State of Gujarat was also selected to participate in a pilot project.
- Framework proposal: Active stakeholder engagement was conducted to develop a proposed framework for a platform to support code implementation.
- Developing the platform: An online platform was created to facilitate and empower the adoption, compliance, and enforcement of ENS in housing projects in Gujarat and the pilot demonstration through Ahmedabad city.
The Beta version of the platform will be launched in August 2022.
