Abstract

 
Campus outdoor urban spaces consider effective spaces for students to take a walk or
engage in recreation and social activities or studying. A comfortable thermal
environment is extremely important for students to enjoy the outdoor urban spaces.
Wherefore thermal comfort in urban spaces is a crucial issue, but the warmer urban
climate may have some negative impacts on outdoor thermal comfort of student in
campus. Therefore, the aim of this study was to investigate the effect of aspect ratio of
urban space, which is one of most effective strategy to improvement outdoor thermal
comfort. ENVI-met numerical simulation applied to examine a series of aspect ratio
scenarios. ENVI-met run for main entrance space in BUE campus, Cairo, Egypt. The
effects of aspect ratio on outdoor thermal comfort dealt with in detail. The results
show that aspect ratio (H/W=3) could be considered starting point to respect outdoor
thermal comfort.
