Abstract

Vernacular shading systems dealt with solar radiation as the dominant components driving the heat balance equation for the hot, arid climate. Its positive climatic effectiveness as a traditional solution are herewith questioned. In order to improve the microclimate conditions at pedestrian level three different shading scenarios addressing the form and the opening of shading devices were simulated using CFD Fluent, based on two dependant variables including air temperature distribution and wind velocity. The findings show that typology and the opening locations are the paramount factors in providing a temperature reduction in the urban scale.
