Resumo: A building constructed according to the climatic characteristics in where it is inserted is important condition to reach thermal comfort and energy saving. However, into the brasilian s housing production predomine standardized architecture models all over the country, wich does not distinct the different local climates, producting, many times, environments without thermal comfort. Factors as the building arrangement, the glazed oppening s dimensions, its exposition to the sun and the thermal properties of the construction materials that compound the buildings envelope are points that define a better thermalenergetic performance. Therefore, this work evaluated the influence of the envelope shading and absorptance to the thermal performance and the energetic consumption of multiple housing buildings situated in Meceió AL having as studing object a model that represents a tipical vertial building tipology developed by PAR Programa de Arrendamento Residencial (Housing Leasehold Program). The methodology is based on parametric analisis in order to compare the reference model to some proposed parameters (solar protection devices, the surroundings and the external walls absorptance), using computer simulation by the EnergyPlus 4.0 software (Energyplus, 2009). To reach the proposed aims there werw vary a parameter by turn, maintaining the other several characteristics of the reference model. The results indicated that the use of solar protection devices and the profit of the building arragement morphology contributed to a better thermal and energetic performance of the building. The predominance of light colors on the external walls was a positive aspect to get fortunate thermal results, thus, is recomended that this characteristic be kept on the city housing programs of Maceio, because it contributed to the energy consumption reduction.
