Abstract
This paper describes a numerical analysis for investigating effective window area ratio of windows with near infrared rays retroreflective film (RRF) to improve thermal environment in summer season using CFD analysis coupled with directional radiant computation In the present analysis, effects of installing the RRF windows on the thermal environment were compared with those of wall greening under the following three different area ratios of each window: 25%, 50%, 67%. From the results of the analysis, it was found that the effects of installing the RRF windows on both improving the thermal environment and mitigating the thermal stress for pedestrians were larger than those of the wall greening even when the window area ratio was set to 25%.
