The power of passive cooling solutions in Bangladesh and Indonesia

The document details the application of reflective cool roofs in Bangladesh and Indonesia, demonstrating significant reductions in indoor and surface temperatures for low-income housing and industrial facilities.

• In the Kerail slum in Bangladesh, the application of reflective paint as a cool roof solution led to a surface temperature decrease of 12.3°C during peak times and an average indoor air temperature reduction of 3.5°C.
• In Jakarta, Indonesia, cool roofs applied to low-cost housing reduced indoor air temperatures relative to the outdoors by 2°C for clay tile roofs and 2.9°C for asbestos roofs when outdoor temperatures reached 34°C or higher.
• A 5,200m² cool roof installed in an Indonesian industrial building reduced indoor air temperatures from 40.8°C to 30.4°C during noon-time outdoor temperatures of approximately 34°C, benefiting 500 shift workers.
• Beneficiary surveys in Indonesia showed a total shift in thermal perception: while 94 percent previously described temperatures as hot or very hot, 100 percent reported feeling neutral, cool, or cold after the cool roof application.
