The integrated day and electric lighting research group work on advanced systems for optimal use of daylight in buildings, with the aim to improve user comfort and health, and reduce energy consumption.

The group has set up a sophisticated daylighting laboratory with, among other, a scanning sky simulator and an automated heliodon, which allow reproducing with very high precision all daylight conditions that exist around the world. Several anidolic (non-imaging) daylight transmission systems have been developed and tested by the group. Furthermore, a bidirectional reflection and transmission photogoniometer has been developed to test the characteristics of advanced glazing.

More recently, research related to visual and non-visual aspects of light on human physiology and behavior has been carried out under the supervision of research associate Dr Mirjam Münch, who set up a photobiological laboratory with different light sources for this purpose. Her work was funded by Velux Foundation.

Current research focuses on high-resolution mapping of the sky and ground dome.

Work in this field is fully incorporated in smart building control research and the development of advanced glazing (microstructured, thermochromic).
