    Transparente Wärmedämmung eines Wohnhauses in Shanghai, VR China

    Südlich des Yang Tse Flusses ist es in der VR China nicht üblich den Wohnraum zu beheizen. Die Raumtemperaturen fallen deshalb im Januar im Monatsmittel auf Werte um 9 Grad C. Mit Hilfe passiver Solarenergienutzung durch transparente Wärmedämmung der massiven Außenwände kann der Wohnkomfort chinesischer Wohngebäude ohne Einsatz fossiler Brennstoffe erheblich verbessert werden. Zur Erprobung der Wirksamkeit von transparenter Wärmedämmung (TWD) wurden in Shanghai 1991 ein in chinesischer Bauweise ausgeführtes Wohngebäude mit 40 qm TWD-Fassade erstellt. Ein zweites, bis auf die Wärmedämmung identisches Gebäude, wurde unmittelbar neben dem passiv-solar Haus gebaut und dient während der Meßphase als Vergleichsobjekt. Die beiden Gebäude besitzen ansonsten, wie in Shanghai üblich, kein konventionelles Zusatzheizsystem. Im Rahmen dieses wissenschaftlichen Beitrags wird über die Konzeption und Konstruktion der Gebäude berichtet. Auf Grundlage der in China erfaßten Daten wird die Funktionsweise der TWD-Fassade und ihre Auswirkungen auf das ansonsten unbeheizte Gebäude dargestellt

    In 1988 a semi detached 2 1/2 storey house with 65 qm transparently insulated walls was erected in Freiburg. Building has been occupied since December 1988. This privately financed project demonstrates that a solar house with a large area of TIM facade and additionally a sunspace could provide sufficient heating comfort and could achieve an apealing appearence. The design of the solar components, which is based on reserach development at the Institut für Solare Energiesysteme (ISE), is reported. First experience shows the feasibility of transparently insulated buildings

    The application of transparent insulation materials (TIM) for space heating in existing buildings is demonstrated in the project "Sonnenäckerweg / Freiburg, FRG". A two-storey residential building, which was originally built at the end of the fifties, was renovated with TIM. This building consists of 8 apartments and has a floor area of 400 mhgih2. The retrofit involved the installation of TI elements on the south-east and the south-west facades. The elements include roller blinds for heat control. Since Dec.'89 the building has been occupied and extensive measurements have been made in both houses. The results from 1990 will be reported. In comparison to conventional insulation, TIM buildings were able to save 50% of the annual energy needs for space heating

    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
