Abstract

Refuge floor is considered as a temporary safe place for evacuees in super high-rise buildings and is a prescriptive requirement in Hong Kong’s Building Codes. The degree of safety of refuge floors under fire situations may be impaired if the floor is affected by smoke from other floors. In the circumstance, Hong Kong’s code prescribes that cross-ventilation should be provided in refuge floor so as to prevent smoke logging. This article reports studies on wind and smoke interaction at a refuge floor by using reduced-scale experiments in wind tunnel and computational fluid dynamics models. Results have indicated that cross-ventilation induced by permanent opening to the external may not guarantee that smoke logging will not happen in refuge floor.
