Altbausanierung mit transparenter Wäremdämmung

Transparent insulation materials (TIM) are a passive technology. With TIM-technology solar-energy can by used for space heating in new and existing buildings. The demonstration project "Sonnenäckerweg/Freiburg" involved retrofitting a double-storey residential house (8 apartments, 400 square meter floor area) built in 1950 with TIM. The south-east and south-west facades were covered with TI-Elements (120 square meter aperture area) and opaque insulation was installed on the other exterior surfaces. The windows and TI-Elements were equipped with rollerblinds for sun and heat protection. We began monitoring the building once it was occupied in Dec. '89. First results show the efficiency of the transparently insulated building with an air-heat recovery system
