In one Indian city, reflective paint and bus stop sprinklers offer relief from killer heat

[...]

City officials, with help from climate and health researchers, have implemented two simple yet effective solutions to help those affected most by heat: the poor and those who work outdoors. By painting tin-roofed households with reflective paint, they’ve reduced indoor temperatures, which otherwise might be up to 5 degrees Celsius (9 degrees Fahrenheit) hotter than outside. More recently, the city hung curtains woven of straw and water sprinklers at one bus stop so commuters can get relief from the sun and heat. Officials said they plan to expand the idea to other bus stops in the city.

Residents said both measures have been a relief even as they brace for at least three more months of sweltering summer.

Throughout the city’s low-income neighborhoods, hundreds of tin-roofed homes have been painted with reflective paint that helps keep the indoors cooler. Residents said their houses were so hot before the roofs were painted that they would spend most of their time outdoors under any shade they could find.

In Ahmedabad’s city center, a 25-meter stretch of a bus stop has been draped with mats made of straw which, when sprinkled with water, immediately cool the hot wind. Sprinklers installed on the bus stop roof lightly spray cool water on the commuters below, providing instant relief from the blazing heat just a step away.

“When nothing like this was here, it was really hot. What they’ve done is really good. Senior citizens like me can get some cooling from the heat,” said 77-year-old Ratilal Bhoire, who was waiting under the sprinklers with his daughter. Bhoire said when he was younger, Ahmedabad was hot, but it was still possible to walk many kilometers without feeling dizzy, even at the height of summer. “Nowadays you can’t do that,” he said.
