Use policy support to encourage appropriate building design
As the first measure to reduce the amount of energy needed for space cooling, proper building design can improve natural ventilation and thermal insulation, reduce air leakage, and improve internal and external shading by incorporating advanced envelope components such as reflective roofs, as well as passive-building design elements, integrated storage and renewables. Building energy codes have proven to be a highly effective instrument to improve building energy performance. Urban design, in particular the integration of green and blue areas, also contributes to reducing cooling demand.
Regulation and financing to provide access to collective cooling spaces for people without household AC is also critical to protect the most vulnerable, especially in the developing world.
