Abstract
A testhouse was set up on the Institute's test area to investigate the behaviour of passive solar components designed for application within the residential hous project of Kaiser Bautechnik in Düsseldorf/Hellerhof, FRG. Results are presented from measurements between January and April 1989 for - a double glazing with integrated roller blind and low emissivity coated inner glass pane - a transparent wall insulation system with integrated roller blind. Results are given in combination with the measured climate conditions. The U-value of the glazing was found to be 1.1 W/qmK with the blind closed and 1.8 W/qmK with opened blind. The effective monthly U-values of the transparently insulated wall vary between -0.9 and -2.9 W/qmK. Thereby the wall's heat losses were decreased about 80 % in comparison to an opaque insulated wall having a similar U-value. Heat gains to the room of 65 kWh/qm were achieved. The system's design was found to fulfill the required properties. A fewimprovements wer e suggested.
