SESBE’s technical and research activities were focussed on different levels. The main basic activity was material development, where different materials for the façade panels were developed. Another activity included material functionalization, which gives the materials additional self-cleaning/easy-to-clean, heat reflecting or moisture buffering properties. Materials were then combined to façade panels, which were tested and modeled. Performance tests were done as demonstration objects exposed at two different European locations (Spain, Poland).
