New Delhi, July 12 (IANS): Delhi Chief Minister Sheila Dikshit Friday urged the Central Public Works Department (CPWD) to promote green buildings, saying such structures were the answer to the rising power consumption.

"Green buildings alone will be an answer to the kind of power consumption we are witnessing currently. I will be grateful to CPWD if they bring out manuals for green buildings in the city," Dikshit said, addressing a gathering at the 159th CPWD Day.

Union Housing and Urban Poverty Alleviation Minister Girija Vyas was also present at the function.

Describing the concept of green building as "least expensive", Dikshit suggested how power consumption can be "substantially" reduced by painting the roof white.

The chief minister also stressed the need for recycling waste.

"I am very happy that CPWD has started building bricks from waste. But I am afraid we must give it a big push as there is resistance to the building bricks made from malba (construction rubble) as these bricks are not considered good," Dikshit said.

She also expressed concern that Delhi produces 10,000 tonnes of waste each day.

Dikshit hailed the CPWD for completing all the infrastructure work on time for Commonwealth Games, which she described as a "game changer".
