ANALYSIS OF PERFORMANCE OF NIGHT VENTILATION FOR RESIDENTIAL BUILDINGS IN HOT-HUMID CLIMATES

16760

Night ventilation is one of the passive cooling techniques commonly used and various theoretical and experimental studies on this subject are available in the literature. However, the effects of climate change are not taken into account. The efficiency of night ventilation can change based on the increasing outside airtemperature, which can be caused by global warming because global warming can lead to increase cooling demand in buildings. In this study, impact and performance of night ventilation on cooling load is examined based on location of insulation layer and air exchange rate in an apartment block located in Izmir under climate change by using simulation tool.As a result, it is seen that cooling load in hot-humid climate can be reduced by 13% with night ventilation in spite of climate change but its contribution has decreased over time. Meanwhile, air exchange rate has a significant impact on performance of night ventilation and location of insulation layer on outside walls has been found to have non critical effect.
