Albedo effect of external surfaces on the energy loads and thermal comfort in buildings

The study was applied for a housing building situated in a Mediterranean climate zone of Algeria, in particular the city of Skikda. The study was carried out considering the variation of the building envelope parameters seeing, orientation, outside reflectivity, thermal mass and insulation of the external walls of the edifice. The results obtained from modeling simulation, using TRNSYS software, shown that the thermal insulation combined with orientation and high solar reflectance, has influenced in a positive way the indoor air, thermal comfort levels and energy efficiency towards a better environment for the inhabitants.
