Abstract


On account of the global warming, there is an increased concern about the overheating risk in free running buildings. This study investigates the influence of local energy efficiency standard TS 825 on summer thermal comfort together with the impact of climate change. It concentrates on a typical apartment building in the context of Istanbul, Turkey by using energy simulation tools EnergyPlus and DesignBuilder. The paper starts with a brief introduction of the concepts of common adaptive thermal comfort models. This is followed by a description of the method. Then the required hourly weather data sets for future use are prepared and two thermal model variations are analyzed with a standard weather data set, as well as the IPCC climate change scenario A2 for the 2020s, 2050s, and 2080s.  Lastly, the simulation results which are evaluated based on adaptive thermal comfort approach according to European Standard EN 15251 are shown in detail. The results present an important effect of the climate change on summer thermal comfort and they show small differences in the amount of comfortable times in summer between apartment buildings applied measures in TS 825 and not applied them. In addition, energy efficiency standards in buildings are the key to vary level of thermal comfort conditions in free running buildings.
