Climate change is recognized as a critical global challenge for the 21st century. This work aims to analyze, through computer simulation, the effects of global warming on the thermal and energy performance of social housing implanted in the Brazilian Savannah. The methodology consists of preparing future climate files; preparation of intervention proposals in the object of study defining six typologies (Tbase, T1 to T5); classification of energy efficiency, analysis of thermal comfort, and estimation of the thermal load for cooling. Under the effects of global warming, T5 showed the best thermal behavior - 1,148 hours in the Base Scenario and 6,841 hours in 2080. Base and T5 have energy efficiency ratings of “C” and “A” in the Base Scenario, respectively, and both are “E” in 2080. It is concluded that considering the useful life of buildings, it is necessary to rethink current construction specifications to absorb the impacts of climate change. Guidance is provided on how to build today to ensure habitability in future climate scenarios.
