Application of CFD to Building Thermal Control Analysis

Abstract

Building-integrated photovoltaic system is to import a photovoltaic panel system into the shell structure of a building by using building design techniques, so that the system constituents not only generate power, but are also a part of the building’s shell. If the photovoltaic panel is integrated with a sun shield, a power benefit could be obtained and both solar irradiation and the cooling load could be reduced. This study aimed to use CFD technology for analysis of building surface thermal control and flow field simulation, and further discuss the effects of the relative position of the sun and atmospheric wind flow field on the distribution of building surface temperatures and flow fields at different hours and in different seasons. Understanding the sun's position and other climatic conditions accurately is helpful for locating solar panels and solar collectors on buildings.
