Mumbai (PTI) : Environment-friendly and energy - efficient buildings are increasingly becoming popular and may grow over three times in the next five years, thereby offering new opportunities to the beleaguered construction industry, a government official said on Friday.

"Today, India has close to 30 million square ft of green buildings; an amazing achievement given the fact that we had only about 20,000 square ft in 2003 when the movement started here," Ajay Mathur, Director General for Bureau of Energy Efficiency (BEE) under the Ministry of Power, said in a release here.

"Market estimates take the figure to over 100 million square ft in the next five years, opening big opportunities for the industry," Mr. Mathur said.

A green building uses less energy, water and natural resources, creates less waste and is healthier for the people compared to a standard building, according to the Indian Green Building Council (IGBC).

The Bureau of Energy Efficiency is adopting various mechanisms for reducing power consumption substantially in a bid to combat climate change.

BEE, which introduced star rating for determining the energy efficiency of electronic home appliances, has started a similar rating system for commercial buildings.
