India’s most energy efficient building

India’s most energy efficient building

The 43,000 square foot Energy Management Centre building in Kerala is not like any other government buildings but is a structure worth emulating. The EMC building inside Sree Krishna Nagar was one of the six in the world and the only project listed from India in UN’s Global Status Report 2017: Towards a zero-emission, efficient, and resilient buildings and construction sector released in May 2017.

The EMC energy positive campus in Kerala was developed to allow natural cross-ventilation from building forms and openings. The campus has a 30 kilowatt grid-connected solar capacity that exports around 50 kWh per day on average, with a doubling of the capacity under implementation. The EMC campus also uses daylighting controls, chlorofluorocarbon and hydrochlorofluorocarbon free heating, ventilation and cooling systems, along with a halogen-free fire-fighting system. Solar reflectance index coating combined with high-albedo paintings and turbo-vents for passive cooling have been used on the buildings, and tropical rainforest trees help create cool and shaded surroundings. For the construction process, certified green construction materials, recycled wood boards, low-emitting paints and adhesives, and green-plus certified carpets have been used. Building envelope intensities are less than 10 kWh/m2/year.
