|Measurement||Determination of the energetic and visual performance of (transparent) large-scale façade and roof elements under real climate conditions|
|Measurement objects||Membrane elements, glass and metal façades, double skin façades, (switchable) façades, skylights, light-band, sun and glare protection systems and daylight redirection systems|
|Max. specimen size||3.2 m × 2.3 m|
|Slope||0° to 90°|
|Calorimetric measurement concept||For heating and cooling the internal surfaces of the test chamber are equipped with highly effective water bearing absorbers. From the amount of thermal energy required to keep a certain internal temperature the energetic performance of the specimen can be determined. The SHGC as an example.|
|3D robot||To investigate specific aspects of local temperatures, air speeds, heat transfer resistances, and lighting and glare evaluations, the facility is equipped with a three-dimensional robot which can be used to position measurement sensors at any point inside the test chamber.
By constantly moving this mobile sensor platform it is possible to determine multi-dimensional properties like the areal resolved solar or visual transmissions.
