In the Wilhelm-Klauditz-Institute (WKI) a large station for a double climatic simulation has been conceived and installed. With this equipement the physical and mechanical behaviour of large construction elements can be tested under time-laps simulated weathering conditions. It consists of two climate chambers separately adjustable and controlable. Each one has an open longitudinal side where the construction elements to be tested can be installed as a parting wall. The indoor climate chamber has a temperature range of plus 5 degree C to plus 35 degree C with 20% to 95% rel. air humidity. The outdoor climatic chamber with a temperature range of plus 60 degree C to minus 40 degree C and with a rel. air humidity of 20% to 95% has been completed by a solar radiation simulator and a sprinkler. There are constant as well as permanently changing marginal climatic conditions, as for example annual weathering courses, adjustable so that any climate can be simulated. The construction elements c an be delivered and installed with original dimensions with windows, jalousies, doors etc. with a length up to 8,6 m, a height up to 2,5 m, a depth up to 0,83 m and a weigth up to 13t. Here original construction elements can be used and ceiling and roof weigths can be simulated.
