Abstract

Sunlight is strong and skylight is voluminous in the tropics. External multiple horizontal slats are simple but effective to shade the direct sunlight from north-and south-facing windows of a building in a tropical region. The device still allows the skylight to pass through and offers comfortable viewing from the interior to the exterior scene. This paper presents technical results of an experimental and simulation study on the use of such device with windows. The paper demonstrates an optimization of energy benefit from using such device on appropriate size of and suitable type of the glazed window.
