Abstract

Corridor, considered as a major form of semi-open spaces, is a partly open comfortable space for people to take shelter from the wind, rain and sunlight in a highly urbanized environment. As a unique Taiwan street culture, there are no studies conducted to explore the influences of corridor buildings on the microclimates. The purpose of this paper is to conduct the computational fluid dynamics (CFD) analysis for resolving the wind environments around the subject building complex with semi-open spaces in a highly urbanized area. In this study, a threedimensional (3D) numerical model is built to replicate the high-density urban building complexes with corridor spaces. By varying the effect of corridor configurations, the wind field were examined to assess the microclimate environments around the subject building with corridor. The obtained results can provide a useful reference for development of the urban design guidelines for the urban renewal.
