Electricity consumption and low thermal comfort in social interest housing (SIH) in southern Brazil are directly related with the low investment to define the materials that make up the envelopes. Through computer simulation, it is possible to evaluate different configurations of a SIH using algorithmic solutions, such as the evolutionary multi-objective, which test different combinations to improve the performance of two or more objective conditions. Aiming at reducing the electricity use intensity and thermal discomfort, this work proposes the presentation of two multiobjective evolutionary algorithms to change the values to be assigned for thermal transmittance of the external walls, the floor and the roof, as well as the solar orientation and the solar absorptions of the outer walls and the roof, with different pre-established values limits. From the analysis of the results obtained in the 10-generation simulation using the EnergyPlus software for the city of Pelotas-RS for each of the algorithms, it was observed that in the best case a thermal comfort level for the occupied hours above 79% was identified. As well as an energy use intensity (EUI) of less than 32 kWh/(m².year). In addition to these results, the discussion presents alternatives for defining the thermoenergetic simulation strategies of large input sets.
