Arquivos climáticos na simulação computacional:uma abordagem termo-energética paramétrica de acordo com a NBR 15.575:2024 para edificações residenciais em Curitiba - PR

Abstract

Given the environmental demands for reducing energy consumption in buildings, computational simulation is increasingly relevant as a predictive tool for energy consumption. In this regard, the choice of the climatic file stands as a fundamental variable for the simulation process, as it characterizes the building in relation to the environment in which it will be constructed. This dissertation presents the impact of the choice of climatic files on the differences in results between them, evaluating the indicators of the brazilian standard ABNT NBR 15.575 for thermal and energy performance. The adopted method involves a comparative approach, divided into five main stages: review, selection, identification, comparison, and analysis, with a special focus on the impact of the choice of climatic files on each indicator and on the analysis of the results obtained through computational simulation. The analysis of climatic files highlighted differences in the minimum temperature amplitude of 6.7ëC and maximum temperature amplitude of 4ëC, as well as a variation of up to 129% in direct normal radiation. The results of the thermo-energy simulation show significant variations observed between the different climatic files used, with average variations in the PHFT and RedCgTT indicators of up to 13.37% and 2%, respectively.
