Daylighting and Shading of the Energy Efficiency Center

摘要

This work describes the daylighting and shading concept of the recently constructed “Energy Efficiency Center”. There, an efficient utilization of natural lighting in the offices, corridors, function room and technical center was realized by use of a translucent membrane roof with subjacent translucent aerogel modules. Selectively coated solar blinds guide the visual spectrum of the sunlight into the rooms while blocking the infrared parts. Roller blinds for glare protection with special low-e-coatings improve thermal comfort in the office rooms. A high-level building automation system controls the different systems. The goal was to minimize the energy consumption for artificial lighting and at the same time to minimize the solar energy input into the rooms in summer while providing the highest possible thermal and visual comfort to the users.
