A semi-empirical ventilation model was proposed for cross-ventilation. This model isbased on local dynamic similarity theory andwas coupled with COMIS and TRNSYS, whichare widely used for energy conservationsimulation. A simulation study was performedon a typical detached house in Japan to evaluatethe energy conservation effect of crossventilationduring the day. The conventionalOrifice model overestimated the ventilation flow rates compared to those by COMIS-LDSM, especially when the approaching flow was not normal to the upwind openings. It tended to overestimate energy reduction loads when cross-ventilation was utilized.
