Effects of radiative exchange in an urban canyon on building surfaces’ loads and temperatures
Heat exchange between buildings and the surrounding environment is due to convective and radiative heat flows. In this study a detailed building energy simulation tool (BES) is used to analyze the effect of multiple shortwave and longwave inter-reflections exchanges between neighboring buildings with the main purpose to evaluate their influence on the heat fluxes on the external walls of street canyon buildings. These radiative exchanges modify the canyon microclimate thus influencing space cooling and heating demand of buildings.
