Impact of climate change on passive design strategies

Abstract

The aim of this study is to determine the changing contribution of passive design strategies to maintain thermal comfort conditions under climate change in Turkey. A bioclimatic chart developed by Givoni was used for the analysis of architectural design philosophy associated with passive design strategies with the onset of climate change. Typical meteorological year 2 and predicted future weather data were used for plotting hourly climate parameters on the psychometric chart. The largest three cities in Turkey have been preferred as case studies using all year analyses. The results show that the level of thermal comfort increases in Istanbul and Ankara and it decreases only in Izmir due to the influence of climate change. Passive solar heating and high thermal mass/solar heating are effective solutions for the improvement of thermal comfort in winter for all cities. Although the contribution of these changes are for 2020, 2050 and 2080, they have a relatively positive impact at all times. Meanwhile, ventilation/thermal mass/evaporative cooling is an effective passive cooling technique for climate change in all cities. It is very clear that the demand for active cooling in buildings will increase in the future.
