| Research Abstract |
Wind-induced natural ventilation is beneficial to obtain thermal comfort in the hot summertime. However, rooms in the building are obligated to have the mechanical ventilation device due to the regulation in Japan, which is contrary to saving energy. This work aims to evaluate and predict natural ventilation performance of the residence with the device promoting wind-induced ventilation. The flow characteristics around the device were clarified based on wind tunnel test, and substantial ventilation performance within occupied zone was analyzed by CFD analyses.
