East India's first net-zero building coming up at Bhubaneswar.

Producing as much energy as it consumes by using geothermal cooling systems and solar energy, eastern India's first net-zero energy building will come up at Bhubaneswar next year.

Spread over three acres, the project will house the new office of the Grid Corporation of Odisha Ltd. (GRIDCO), under the Odisha government's energy department.

'The building invites direct natural sunlight and screen radiation. It would have photovoltaic glass panels and geothermal cooling systems at strategic places along with its indigenous solar generating systems so that is sustained itself with own energy,' Kolkata-based architect Abin Chaudhuri, who has designed the structure, told PTI here.

The average running cost of energy for a standard building of this capacity amounts to Rs. 10 per square feet, however, for this green project it will not be more than Rs. 2 per square feet.

'Very roughly I am assuming that the Energy Performance Index (EPI) of the building will be roughly 90 KWh/sqm/year. The same can be generated with 180KWp of solar panels,' the architect said.

The construction is expected to start this year and will be ready by the end of next year.
