Wind pressure coefficient distribution of detached houses in a dense residential block

Abstract

In a dense residential block, the external airflow patterns around the site should be understood from the design stage to improve cross ventilation for enhancing occupant's comfort and saving energy. This study concluded the height and distance of the neighbor building have a significant contribution to the external airflow patterns. This conclusion was derived through surveying the blocks density of the main residential areas in Tokyo. Then, using a wind tunnel, we tested the influence of changing the height and distance of the neighbor building on the wind pressure coefficient under two scenarios; the typical residential models and the models with ventilation enhancing strategies.
