MEASUREMENT OF HEAT TRANSFER BY COMPONENT OF WINDOWS WITH SOLAR CONTROL DEVICES UNDER ACTUAL ENVIRONMENT: Study on inner roller blinds

In recent years, passive designs, that acquire solar radiation from large windows during winter time, are becoming widespread. However, due to privacy issues, there are some houses in which curtains and other shading devices remain closed throughout the year. In this research, we focused on the roller blinds that can control the solar radiation and view, in response to the weather conditions and the surrounding environment, and measure the solar heat gain and the heat transfer by component of the windows with roller blinds under the actual environment.
