Abstract

In recent decades, climate change has received increasing interest from researchers given the growth and implications of this phenomenon. The originality of this study is in evaluating the Passivhaus EnerPHit standard for adapting buildings to climate change. Another innovative aspect of this paper is to investigate the impact of climate change on heating and cooling energy demand in tertiary buildings in Algeria. This study considered two Representative Concentration Pathway scenarios of the Intergovernmental Panel on Climate Change (RCP4.5 and RCP8.5). Future hourly weather data were generated by the Meteonorm software for 2050 and 2080. These data were then used as inputs to DesignBuilder software, to simulate the impact of climate change on the heating and cooling energy demand of the building. Further, climate change adaptation measures were assessed separately and then gradually combined. The results show that the annual heating energy demand of the investigated building will decrease by 20.83% in 2050 and by 42.93% in 2080, while climate change will increase cooling energy demand by 111.25% and 268.91% in 2050 and 2080 respectively, according to RCP8.5. Unlike heating, the greater the climate change, the more challenging it is to achieve the EnerPHit cooling energy demand limit. The study results show also that the implementation of the adaptation measures allows reaching the EnerPHit standard in all scenarios, with an average of 88% reduction in heating energy demand and 76% reduction in cooling energy demand, compared to the base case scenario with the current climate, 2050 and 2080.
