Impact of changing solar screen configurattions on energy and daylighting performance in residential desert buildings

In desert sunny clear-sky regions solar penetration can become excessive. This can cause non-uniform daylight distribution, glare and high solar heat gain, affecting both visual and thermal comfort. Shading devices, such as solar screens, were usually used to diffuse and prevent direct solar penetration into spaces. This paper investigates the impact of changing solar screen configurations on energy daylighting performance in a typical residential living room space under the desert sunny clear-sky.
