Abstract

Natural ventilation performance can be assessed with computer simulation. Generally, there are two types of computer simulation methods: BES (Building Energy Simulation) and CFD simulation. In order to supplement each simulation's weaknesses, the integration of energy simulation and the CFD program was recommended. Through the integration of BES and CFD simulation, this study analyzes the thermal environment of apartment housing to which natural ventilation is applied. The efficiency of the coupling method is analyzed by comparing the results of coupling with those of BES. Also examined is the utility of the airflow rate, set as the transfer element greatly influencing the results of coupling interpretation under certain conditions.Due to certain natural ventilation conditions that make it impossible for BES to perform an accurate calculation of airflow rates, the results were compared with the airflow rate taken into account as an important factor. Under the condition with higher airflow rates, since heat transfer due to airflow is dominant, the convective heat transfer coefficient does not have a significant influence.
