High albedo surfaces
Web19 de dez. de 2024 · The technical name for a roof that reflects heat is that it has a high albedo. High-albedo roofing has two scientifically proven benefits: it helps to mitigate the urban heat island effect and reduce cooling energy demand and costs. It can also increase thermal comfort in non-conditioned buildings. Benefits are both direct and indirect. Webspeed) (Oke, 1987). A higher albedo signifies that less short wave radiation will be absorbed by the surface, resulting in lower surface temperatures. In general, high …

WebSurface albedo shows a slight minimum at the equator because of dense evergreen forest and a secondary minimum at 40°S latitude because of the large extent of open ocean at this latitude. Increases at 25° to 30° north and south result from the presence of subtropical deserts with relatively high albedos (>40%).
