Abstract

Urbanization, like heatwaves, influences the internal temperatures of dwellings. Therefore, the objective of this paper is to analyze the impact of coupling microclimatic data in thermo-energy simulations and the thermal conditions of social housing during a heatwave. The chaining method was employed, collecting temperature and humidity data during a heatwave in São Carlos-SP. Based on this data, a simulation was set up in ENVI-met, and its results were coupled with EnergyPlus through the BCVTB software. The results indicated that the occupied hours presented health risks to the residents, in addition to an increase in energy consumption of 16.39 kWh. The feasibility of coupling microclimatic data for studying mitigation solutions for the impact of extreme climatic events and different urban morphologies was confirmed.
