Andhra Pradesh becomes a national leader in building efficiency by adopting Energy Conservation Building Code


After more than a year of technical review and extensive stakeholder consultation with developers, builders and efficiency experts, Andhra Pradesh, India’s fourth-largest state, has announced the adoption of the Energy Conservation Building Code (ECBC) for large commercial and public buildings and major retrofits After the code becomes effective in August 2014, the innovative framework includes phased-in implementation that will require compliance after training workshops and awareness building among municipal officers and real estate developers.


The ECBC is expected to dramatically reduce energy consumption by as much as 40-60 per cent, increase electricity reliability, and enable consumers to save money.  In fact, adopting the code in Andhra Pradesh could save the amount of energy by 2030 that’s needed to power 8.9 million Indian households annually over that time frame, according to a new analysis by the Natural Resources Defense Council (NRDC) and Administrative Staff College of India (ASCI).


“Improving building efficiency presents a huge opportunity for developers, investors, building tenants and the country as a whole,” said Anjali Jaiswal, Director, India Initiative, Natural Resources Defense Council. “Implementing building energy efficiency standards will drive much needed sustainable growth, cut costs and save energy for Andhra Pradesh and India.”


Andhra Pradesh’s innovative adaptation of the ECBC makes it the most comprehensive and rigorous code adopted by an Indian state to date.


“Energy conservation is fundamental to supporting the economic development of our state,” said PK Mohanty, Chief Secretary of Andhra Pradesh. “The Energy Conservation Building Code is a critical step to save energy.”


Energy savings and air pollution subtraction:  According to a new analysis minimal code compliance by commercial buildings in Andhra Pradesh – 40 per cent complying with the ECBC, 5 per cent exceeding the code – translates to 86 terawatt hours of cumulative energy saved by 2030, enough to power as many as 8.9 million Indian households per year over the next 17 years based on the current level of annual energy consumption. Even more impressive, if states across India adopted the Energy Conservation Building Code and developers participated in strong programs for rating commercial buildings, an estimated 3,453 terawatt hours of cumulative electricity could be saved by 2030. This is equivalent to powering 358 million Indian homes annually between 2014 and 2030 based on current annual consumption levels for electrified homes. Additionally, 1,184 million tons of carbon dioxide emissions could be avoided by 2030 – equivalent to the annual emissions from more than 17 typical coal-fired power plants over that same time period.
Several of the green buildings in Hyderabad, such as the Confederation of Indian Industries-India Green Building Centre and the Infosys campus, demonstrate the payback potential of energy efficiency. NRDC and ASCI’s case study of the Godrej Bhavan energy efficiency retrofit in Mumbai, supported in part by Shakti Sustainable Energy Foundation, shows the huge financial savings potential in energy efficiency upgrades and a remarkably low payback period of less than five years.


The code allows for flexibility in implementation by offering a prescriptive method, which provides a list of requirements for code compliance, and a Whole Building Performance Method, which uses architectural design software to optimise the buildings energy performance while minimising costs. Having the option of either method gives developers, architects and designers the ability to respond to changing technologies and prices over time.u


  • ECBC to reduce energy consumption by 40-60%
  • AP will save energy by 2030 needed to power 8.9 million households
  • 1,184 million tons of carbon dioxide emissions could be avoided by 2030
  • With developer participation 3,453 terawatt hours of cumulative electricity to be saved by 2030.
