Impacts of a warmer world on space cooling demand in Brazilian households

Air Conditioning (AC) appliances are a highly effective adaptation strategy to rising temperatures, thus making future climate conditions an important driver of space cooling energy demand. The main goal this study is assess the impacts change on Cooling Degree Days computed with wet-bulb temperature (CDDwb) and household demand in Brazil. We compare needs under three specific warming levels (SWLs) scenarios (1.5 °C, 2 °C 4 °C) baseline historically observed meteorological parameters by combining CDDwb projections end-use model evaluate requirements air conditioning. effects were isolated, no expansion AC ownership considered. Carbon dioxide (CO2) emissions associated also calculated. Results show increase both average electricity consumption for global all Brazilian regions. Northern region shows highest (187% SWL °C), while Southeast presents response (326% compared baseline. At national level, SWLs grow 70%, 99% 190%, respectively.
