Refuge　floors　should　be　provided　in　all　buildings　exceeding　25　storeys　for　fire　safety　following　the　Hong　Kong　Building　Code　on　means　of　escape,　and　at　least　two　opposite　external　walls　should　be　open　to　provide　adequate　cross　ventilation.　Wind-induced　flow　around　two　adjacent　rectangle-plan　high-rise　buildings　with　or　without　opening　refuge　floors　were　investigated　by　computational　fluid　dynamics　(CFD)　in　this　paper.　The　flow　pattern　and　pressure　distributions　around　these　two　buildings　were　addressed.　The　results　are　believed　to　be　helpful　for　the　proper　design　of　the　smoke　control　system　and　ventilation　system　in　buildings.
