Study on the spectral albedo in the geometrically complex urban spaces
نویسندگان
چکیده
In recent years, high-albedo materials and products have been utilized for urban building roofs and roads to lower their surface temperatures. These high-albedo materials and products include those with spectral selectivity. Accordingly, a numerical simulation was conducted to investigate the spectral dependency and characteristics of the urban albedo. The distribution of the spectral albedo relative to the albedo over the entire spectrum agreed well between the experimental (Itoh & Ashie 2008) and numerical investigations. The effects of the spectral selectivity of urban materials on the urban albedo are discussed using the results from the numerical simulation.
