ANALYSIS OF THERMAL ENVIRONMENT NEAR WINDOWS BY CFD ANALYSIS CONSIDERING THE INFLUENCE OF WINDOW TREATMENT ON INDOOR SOLAR RADIATION DISTRIBUTION

There has been an increase in the number of passive houses with large windows to acquire solar heat. This study aims to evaluate window treatments such as roller screens based on thermal environment, and to make it possible to select them appropriately. The characteristics of the treatments are analyzed through experiments, and the necessity of thermal environment evaluation in consideration of solar radiation is demonstrated. Combining solar radiation analysis and CFD analysis, we developed the thermal environment simulation method considering BSDFs and solar radiation. Through case studies using this method, basic findings for the selection of treatments were summarized.
