Building density in a master plan directly affects the outdoor physical environmental quality residential area. Inappropriate design of layout may cause impact on external comfort, such as lack air movement. To tackle this problem, dimensional variable, named ventilation space was defined to feature building plan. It consists gable and fore-and-aft space. The Reynolds averaged equations renormalization group (RNG) κ-ε turbulence model used simulate wind condition some typical layouts under weather Hangzhou, China. simulated conditions were assessed using criteria, speed ratio at key locations pedestrian level. effects movement discussed an optimal derived for each modeled layouts. set results expected be rule thumb by architects planners planning stage.
