Advantages of the collector and possible applications

The described semi-transparent collector is a multifunctional architectural design element. This offers a new market potential for solar thermal energy use. At a certain distance the structure of the small openings appears as a homogeneous semi-transparent area with the silhouette of the channels. This offers interesting possibilities in design: straight vertical or horizontal channel arrangements […]

Calculation assumptions

The reflectivity of walls, ground and ceiling are respectively 0.75, 0.45 and 0.75. The Lighting French Association recommands an illuminance level of 300 lux in a typical office [4] . In this study, the value of acceptable illuminance level has been set to 300 lux. To quantify the mean daylight autonomy in the room, the […]

Global Warming Impact

The results presented in the figure 3 support the idea that if we consider that all building design variables (orientation, materials, SOF, TOF, technology, etc) are maintained constant and only the location of buildings in the city are modify; the emissions related to the energy consumption vary significantly too. It is especially during winter’s month. […]
