Numerical estimation of street canyon albedo consisting of vertical coated glazed facades

The method presented in this paper is a practical procedure for the derivation of a street canyon’s albedo, by taking into account the angle-dependent optical properties of a typical coated (SnO2) glazing. The development of the method is based on the flux transfer theory and can be easily implemented in a computer code permitting exploitation of a series of possibilities, such as street canyon geometry and window to wall ratios (WWRs).
