The high consumption in the buildings sector, in Portugal, implies an obstacle to the accomplishment of the purposes intrinsic to sustainable construction. To change this situation we must encourage the construction of energy efficient buildings based on a set of solutions that strive to reduce the energy consumption of buildings throughout its life cycle, while ensuring comfort for its occupants. The main objective of this article is to analyze proposals that improve energy efficiency in residential buildings, based on the calculation of energy savings associated with the use of air conditioning (to assure a certain comfort temperature) and their payback period. To this end a case study was established. The energy performance assessment, before and after the implementation of the improvement strategies, was done trough a dynamic analysis with the EnergyPlus software. The use of the considered strategies improves the energy efficiency of buildings, such as the case study, with different payback periods.
