Overheating in buildings is expected to increase as global warming continues. This could lead to heatrelated problems ranging from thermal-discomfort and productivity-reduction to illness as well as death. From the indoor-overheating point of view, the sensitivity of 9,216 Dutch dwelling-case to the climate change is quantified and ranked using detailed simulation and post-processing calculations. The results show that the sensitivity depends significantly on the dwelling’s design/operation characteristics. Minimally-ventilated dwellings are the most sensitive ones. According to the ventilation rate, shading type, insulation level, and other building characteristics, the sensitivity of dwellings could range from 0.15 to 1.2 indoor-overheating degree /ambient-warming degree.
