The first building in India to use 100% on-site energy generation has reportedly been unveiled by the Government.

Reports claim the Indira Paryavaran Bhawan in New Delhi will house the Ministry of Environment and Forest and accommodate 600 officials.

It is claimed to be India’s first “zero-net energy” building, which will use renewable energy generated within the premises.

The building is designed in such a way that 75% of natural daylight is used to reduce energy consumption. It includes a rooftop solar system, with the electricity being fed to the local grid and also has an energy efficient air conditioning system.

An official statement reportedly said: “Total energy savings of about 40% has been achieved by adoption of energy efficient ‘Chilled Beam’ system of Air Conditioning. This is an innovative air conditioning system, where air conditioning is done by convection currents rather than air flow through diffusers and chilled water is circulated right up to the diffuser points unlike the conventional systems.”
