diffuse sunlight simulator

Daylighting lab

A direct sunlight simulator (Heliodon) as well as a scanning sky (diffuse light) simulator as well as a photogoniometer for the study of directional light transmission and reflection properties of fenestration systems allow testing of scale models and samples.


A photobiological laboratory was set up for studies and research on the effects of light on physiology and behavior in humans.
