The Interaction of Wind Velocity and Air Gap Width on the Thermal Comfort in Naturally Ventilated Buildings with Multiple Skin Facade

Abstract

This paper demonstrates through a sensitivity analysis, an optimal strategy for completing a CFD simulation of this special building envelope. This study also attempts to research a mechanically ventilated building with DSF configuration—a building in terms of indoor microclimatic thermal comfort. The aim of this study is to work out the effect of wind velocity and wind distribution on naturally ventilated buildings with DSF configuration, to work out if a DSF configuration will provide a far better microclimatic thermal comfort through natural ventilation. This study not only defines and analyzes the dimensional parameters of the air gap to maximize airflows, but also explores the importance of design decisions on system performance, such as the interaction between thermal mass and air gap distances and the building facade.
