In order to ascertain the relationship between opening conditions and indoor airflow characteristics, case studies were conducted by performing CFD analysis using the domain decomposition technique. Reproducibility of the domain decomposition technique was verified through wind tunnel experiments, and the correspondence was confirmed to be satisfactory. The authors confirmed the validity of a method of evaluating cross-ventilation performance which uses wind velocity ratios and ignores regional and meteorological locality. The relationship between opening area and wind velocity ratio was also ascertained for each case.
