These house use - 25 square meter, 70 degree tilted southroofs with a TI-system on the basis of a polycarbonate honeycomb material in combination with - temporary heat- and sunprotection by rollerblinds in the TI-roofs and the special double glazings - gas-air heating units with integrated heat recovery - compact design with a high opaque insulation level to guarantee high utilization of the solar gains with a low, additional energy demand. Results, obtained from the detailed monitoring of a testfacade, were used to develop a highly efficient TI-system. The architecture and the project management aim to commercialize the new TI technology.de621697conference paper
