The method for controlling the airflow in and around building in order to improve indoor thermal comfort

Abstract

This paper investigates the method for controlling the airflow in and around a building in order to improve the indoor thermal comfort by utilizing cross-ventilation. In the first part of the paper, field measurement was carried out to evaluate the effects of cross-ventilation on indoor thermal comfort. It was confirmed that the comfortable indoor thermal environment could be attained in a considerable part over summer period by controlling the window opening in order to maintain PMV value within the range -0.5<PMV<+0.5. The latter part of this paper reports on the CFD predictions of flow in and around a building. Here, the effects of the planted trees arrangements around the building, the openings locations and the size of openings on the building were numerically investigated.
