The most recent realization is the Environmental Chamber designed to test new concepts in the performance of the building envelope. The Environmental Chamber provides the setting for building envelope studies on topics such as the following:
The Environmental Chamber consists of two chambers representing indoor and outdoor conditions, denoted as hot and cold boxes. Between the boxes a hollow rectangular frame may be sandwiched, in which building envelope large scale components can be fixed or built up. Lab space is 273 sq. m.
The Environmental Chamber provides a facility for building science studies in many areas such as thermal cycling, heat storage, insulation, thermal warping, freeze-thaw, air infiltration, condensation, air quality, construction productivity and automation, and control strategies. The thermal performance tests evaluate the steady-state and dynamic characteristics of heat transfer through composite wall assemblies of 23'6" height x 13'6" width x 2'6" thick. The facility is designed to test composite specimens with floor structures and fenestration.
