The Effect of Fixed External Shading Devices on Daylighting and Thermal Comfort in Residential Building
Building shading devices can improve the thermal comfort in indoor environment, and also reduce cooling and heating energy consumption in dry and hot climate. This study proposes the different kind of window’s fixed shading devices for energy consumption under near-extreme summer and winter conditio...
