Abstract

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