peer reviewed ; In coming years, global warming will have a large impact on many aspects of the environment and human activities in buildings. The objective of the ongoing study, of which some results are presented in this paper, is to upscale the impact of climate change on the Belgian residential building stock and to evaluate its influence on the future heating and cooling demands. In order to quantify the impact of climate change, this study used MAR regional atmospheric model using MPI and BCC as forcing GCMs for Liege city during the period of 2012-2100. Energy simulations are obtained using MATLAB for four different types of residential buildings (Freestanding, semi-detached, terraced and apartment) in four different representative years (2012, 2021, 2050 and 2100). The present paper focuses on results associated with predicted future heating demands. ; [OCCuPANt] Impacts of climate change on buildings in Belgium during summer
