The design is based on the principle of the "Trombe wall", which itself draws on the principle of solar heat storage behind a transparent outer shell. In this project, the passive use of solar energy is to be transferred and evaluated in a hybrid curtain wall system with transparent and opaque components.
The idea is to primarily work with "low-tech" components, which means common, proven and well-established technologies and materials are used whenever possible, to be then combined in a sophisticated way. The idea for this project originates from an exchange at the COST Action TU-1403 Adaptive Facades conference. The basic idea of the SEBF using low-tech approaches is also rooted in the field of adaptive facades. After all, the management of thermal storage also requires daily or seasonal adaptivity.
