Impact of CH2018 Climate Change Scenarios for Switzerland on today’s Swiss building stock

摘要: The energy demand of buildings heavily depends on outdoor temperature. Current climate change projections suggest an increase in annual mean temperatures of up to 5.4 C for Switzerland until the end of the century. In this study, an existing bottom-up building stock model is coupled with the latest spatio-temporal climate change projections. This allows for simulating the heat demand for each Swiss building for three different climate change scenarios and three periods. It is found that while space heat demand can decrease up to 33% by the end of the century, the need for air conditioning can arise. Furthermore, the impact of climate change differs between regions in Switzerland.
