It helps to mitigate the urban heat island effect and reduce cooling energy demand and costs.

White roofs albedo.

White rooftops, in contrast, scatter a percentage of visible light back into the atmosphere without converting it into heat energy. This albedo could not be practically achieved due to aging effects, obstructions and openings on the roof surface (e.g.,. By increasing the albedo of roof surface, more sunlight is reflected, leading to less heating of the building and the surrounding air.

In general, though, cool roofs result in net energy savings, especially in areas where electricity prices are high. White roofs change surface albedo and affect energy demand. For a cool roof, one that deflects uv radiation and discourages heat retention, go in the opposite direction the spectrum—white.

Such albedos are comparable to the highest available from white roof surfaces. The implications of this finding for green and white roof research are. White is the best color for energy efficiency because of the albedo effect.

Use reflective roofing material or to paint existing roofs white.whiteroofshavegenerallybeenthoughttoreduce summer air conditioning energy demand and change the albedo of the surface. Plain language summary solar reflective roofs (also called white or cool roofs) are a common heat mitigation strategy. Albedo is the ratio of the amount of solar radiation reflected from a surface.

The technical name for a roof that reflects heat is that it has a high albedo. Increase urban green areas with a daily. By increasing the albedo of roof surface, more sunlight is reflected, leading to less heating of the building and the surrounding air.

Benefits are both direct and indirect. Computer models indicate that if every roof in every city were painted white the demand for air conditioning would be reduced, and temperatures in the cities would be reduced by an. There has been quite a lot of buzz in the last day or so about energy secretary steven chu claiming that making the roofs of buildings white (and brightening paved surfaces such as roads and parking lots) would “offset” a large part of the warming effect of humanity’s carbon dioxide emissions.
