Lighting Technology and Passive Solar Systems

Optimal lighting conditions using daylight and artificial light

Planning and designing visual environments to meet requirements is highly important because humans absorb around 80 to 90 percent of information via the eye. In addition, light - especially daylight - has a direct biological and positive impact on people (e.g. in controlling the circadian rhythm). At the same time, demands concerning lighting solutions are rising in terms of energy efficiency and achieving ambitious climate policy targets. For example, lighting accounts for about 15 percent of global electricity consumption and causes approximately 5 percent of greenhouse gas emissions. Good reasons for our experts to carry out groundbreaking projects in order to improve the general lighting situation inside buildings with daylight and artificial lighting, as well as to optimize façades and street lighting.

The main focus of the working group Lighting Technology and Passive Solar Systems is on developing evaluation methods, software and technologies, on validation studies, consulting and knowledge transfer, and also in the area of measuring and testing equipment.
