C. O. Box 155, 2600 A D DELFT The Netherlands ABSTRACT The characterization of passive solar components is due to a number of effects a difficult task. For this reason the CEC-PASSYS project was started. Testcells have been built, testing and evaluation procedures are under development. For the Dutch situation the perspectives by translucent insulated walls have been investigated. The possible energy savings of current wall designs are estimated on 700 to 1200 MJ per m 2 facade. During the summertime the overheating may be a serious problem.
