INTEGRATED EVALUATION OF SOLAR-SHADING DEVICES FOR THE INDOOR CLIMATE CONTROLLABILITY BY CROSS VENTILATION AND SOLAR SHADING

Abstract

While solar-shading devices for buildings' openings contribute to reducing solar heat gain, they can increase airflow resistance of openings. Natural ventilation through windows contributes to the improvement of indoor thermal environment by dissipating indoor heat and increasing indoor air speed. In this study, by measuring independently the solar heat gain coefficient and the discharge coefficient, different types of solar shading devices including the eave are evaluated in an integrated way. When the solar-shading devices are moved and attached on the insect screen due to the outflow, such as in the case of curtains, the discharge coefficient of the openings with the devices decreases considerably.
