Abstract

The objective of this research is to evaluate the impacts of climate change on the thermal and energectic performance of social housing located in the city of Cuiabá-MT, considering proposals to adapt its envelope both in the Base Scenario (1961-1990) and in the prospecting scenarios of heating global - 2020 (2011-2040), 2050 (2041-2070) and 2080 (2071-2100). Prospecting was done through computer simulation, using the EnergyPlus software, following the methodological steps: preparation of future climate files; definition of the type of constructive housing of social interest called "HISp"; implementation of adjustments in the envelope to fit the best levels of Brazilian norms and regulations for thermal and energectic performance in the Base Scenario, obtaining the typology called "HISa"; computational simulation of the temperature and humidity of the outside air and inside the environments of prolonged residence; and comparative analysis of interventions. The quantified impacts point to an average annual temperature variation and relative humidity of the air of 21.5% (+ 5.75 ° C) and 22% (-15.4%), respectively, up to Scenario 2080, if compared to the Base Scenario. The envelopes of the HISa and HISp dwellings were classified as "A" and "D" in the Base Scenario and both as "E" in the 2080 Scenario. The relative energy consumption for artificial thermal conditioning provided for HISp and HISa may rise by 83.75% and 99.63%, respectively, in 2080 compared to the Base Scenario. If the prevailing climatic conditions prevail, they may impede maintaining the envelope's energy efficiency rating as "A," triggering high energy consumption for cooling.
