Indonesia • Betting on reflective roofs to avoid air conditioning

In March 2022, an Indonesian team won the first prize in the Million Cool Roofs Challenge – an initiative launched by the Clean Cooling Collaborative (formerly K-CEP), SEforAll, the Global Cool Cities Alliance, and the Nesta foundation – for its reflective white roofs. The Cool Roofs Indonesia project helped to install white roofs on 70 buildings in 15 Indonesian cities. The various programme initiatives concluded that the installation of reflective roofing structures made it possible to reduce the ground temperature by at least 2 to 3 °C and up to 10 °C in the case of some pilot projects in Indonesia. Access to cooling is a challenge across the domains of development, mitigation and adaptation, for both rural and urban populations.
