Cool Roofs Are Cooling Homes in India

Climate change is driving up temperatures in cities around the world.  When things heat up, many of us simply reach for the thermostat and the air conditioner does its job.  In many parts of the world however, air conditioning isn’t an option and the rising temperatures mean homes become uninhabitable.   But there is a simple and affordable solution – a cool roof can bring down the temperature indoors by a few degrees, which is enough to allow people to sleep in their beds at night.

That’s where programs like the Cool Roof Project – through the Asian Cities Climate Change Resilience Network, and the Rockefeller Foundation – can help.  This program is installing cool roofs in Indore city, India, and residents are already getting relief from the urban heat.  From the Rockefeller Foundation

At Mamta Chouhan’s house, located in one of the 50 locations where cool roof technology has been implemented, a perceptible difference in indoor temperature is seen during high heat days.  The 200 families who have participated in this project have felt similar impacts as well.

Vijay Bhargava, a resident of Indore, reports that TARU came to him and others with an idea to reduce the temperature in their homes. “I didn’t believe it at first,” he admits, “but then they shared the details, including the potential benefits, and I changed my mind.  Afterwards, we felt a five or six degree change.  Incredible!”

He adds that he and his family couldn’t even sit upstairs in the summer before.  “Now, we can sit anywhere in the house, not feeling a difference whether we’re upstairs or downstairs.  It’s meant that we’ve been able to reduce our air conditioning usage substantially.”

They’re collecting data to document the many benefits of this program, and hope to convince local government, real estate developers and other interested parties to include cool roofs in future projects.   Stay tuned!
