摘要

Long-term projections and weatherHeat flux recordsCanopy indicate a change in world climate. This change will be especially observed as an increase in extreme weather frequency. Besides, the resolutions of the extreme events in the urban environment can be more severe due to the thermal properties of construction materials and the wind blockage effect of the buildings. In the scope of this study, the thermal performance of a generic urban areaUrban area is simulated under the weather conditions gathered from Istanbul weather records to quantify the adverse effects of extreme weather events. For this purpose, seven configurations with different physical properties (H/W, albedo level, roof type) are created using the features of the structures in the chosen area.

The seven cases are compared according to the temperature at the building surfaces and heat fluxesHeat flux within the generic urban areaUrban area, and the most suitable combination has been determined accordingly.
