Parametric study on vertical void configurations for improving ventilation performance in the mid-rise apartment building

Double-loaded affordable apartments, which are commonly seen in tropical developing countries, suffer from poor cross-ventilation, particularly on the leeward side of buildings. This study aims to parametrically evaluate closed-vertical void configurations improve ventilation performance double-loaded apartment building using validated CFD models. The include aspect ratio void, pilotis size and fin with various wind directions. results showed that most influential parameter for enabling natural by augmenting pressure coefficient differences windward sides was size, followed direction ratio. Wind influenced more than side, whereas over side. It concluded mass flow rates both could be maximised optimally combining void's under specific prevailing These findings would help create sustainable design guidelines improving incorporating a mid-rise buildings tropics.
