Hundreds of homes in informal settlements in Ahmedabad, India, have been coated with reflective white paint to reduce indoor heat as the hottest season approaches.

The project is part of an international scientific trial aimed at studying how heat affects health and economic outcomes in developing countries, and whether “cool roofs” can help mitigate this impact.

The reflective roofs are intended to keep homes cooler, especially in areas where temperatures exceed 46°C (115°F), and protect residents from the detrimental health effects of extreme heat.

The white coating reflects sunlight back into the atmosphere, preventing excessive heat absorption by the building. This is particularly beneficial for homes without insulation.

Dr. Aditi Bunker, an epidemiologist from the University of Heidelberg, is leading the project, which is funded by the UK-based Wellcome Trust.

Before the project, some residents, like Arti Chunara, used plastic sheets and grass to cover their roofs to combat heat, but these methods were less effective.
