The transmission properties are characterized with BTDF (Bidirectional Transmission Distribution Function) data from a state of the art, bi-directional goniophotometer. Such improvements in the simulation software can drive the dissemination amongst users (lighting industry, energy consultants, architects).
The bi-directional goniophotometer used at the CC EASE can be seen in operation in the image below. In addition to the tasks within the SCCER, the competence center(s) investigate(s) solar energy and components that divert daylight. Further information about the projects at the CC EASE can be found on our website.
