Control of energy transmission through walls and windows
Abstract
New flexible shading and isolation devices were developed to vary the transparency for solar radiation and heatflow through building facades in such a way, that optimal thermal comfort is obtained throughout the year at a maximum solar utilisation. By the use of these control devices passive solar energy gaining structures, such as windows and new transparent wall insulation facades, allow to cover a high portion of the heating demand by solar energy. At the same time surplus solar energy is reflected to prevent overheating during summer period. (ISE)
