Abstract


Glazing materials have a significant impact on the energy efficiency of the building interior. Poorly designed skylights, windows and glazed surfaces can create an uncomfortable environment. The effect of heat gain through an un-shaded glass can be 100 times higher compared to the same area of an insulated wall. Currently, various alternative glazings with different performances are being used daily. There are many choices and alternatives to consider, and careful selection is significant to meet the design requirements. The optical features of glazing materials influence daylighting quality, the thermal characteristics and the potential of energy savings. The increasing interest of skylights as an effective strategy among building professionals and building owners implies that they are keen to know about the performance and energy efficiency of various glazing materials used on skylights. The aim of this study is to review the glazing performance and glazing types that are applied in the skylight roofing system. The review targets at two important factors in glazing performance, namely, solar light and solar heat. The review emphasises this general relationship during the design stage to ensure greater visibility in the product selection, also to ensure various other advantages improved comfort in perimeter zones, reduced mechanical loads and improved energy performance.
