The surface properties of building façades have implications for thermal performance of buildings and might also influence
outdoor thermal comfort conditions for pedestrians. A façade surface property, which is frequently used by building engineers
and specially architects, is the visual reflectance. In this paper, we present the result of a field study, which explores the
relationship between the visual reflectance of building façades and the corresponding surface temperatures. A number of
buildings with diverse façade colours were selected. Surface temperatures, incident solar irradiance, façades´ visual reflectance,
as well as ambient air temperature and relative humidity were measured. The results of the field study display non-random
relationships between the building façades´ visual reflectance and their surface temperatures.
