Influence of climate change on the energy performance assessment of NZEB houses

Abstract The Energy Performance of Buildings (EPB) regulations aim to reduce primary energy use and carbon dioxide emissions buildings, which are the result creating a comfortable healthy indoor environment. In this study, influence climate change on regulatory EPB calculation results is analysed for Flanders region in Belgium. analysis may be used by authorities better define nearly zero building (NZEB) requirements today. Meteonorm has been simulate future based IPCC scenarios urban heat island effect. These climates have implemented Revit-and Excel-based tool that calculates stochastic variation performance six different dwelling typologies, semi-steady state method applied regional rating method. Four packages measures achieve NZEB (thermal insulation, efficient ventilation, renewable technologies,…) considered. use, overheating indicator net heating cooling analysed. As expected, found lead an increase risk, decrease dwellings. Since most cases outweighs total decreases 2050 climate.
