Lighting Technology and Passive Solar Systems

Optimum lighting solutions using daylight and artificial light

The human being perceives approximately 80-90 percent of information visually. Great significance is therefore assigned to the appropriate configuration and design of the visual environ¬ment in accordance with user requirements. At the same time, lighting engineering solutions are subject to energy efficiency requirements. With approximately 10 percent of the total electricity consumption in Europe being used for lighting purposes, efficient lighting solutions can make a substantial contribution to conservative resource utilization and achieving the ambitious goals of climate policy.

Good reasons for our experts to launch pioneering projects for façade optimization, street lighting and general lighting of buildings. Façade technology has a key role in relation to the energy-efficient supply of biologically effective daylight and solar energy.

Carefully planned complex fenestration systems allow for the use of interior spaces (like offices) without them needing to be supplied with heating energy or artificial light for about 80 percent of the time. Thus, the energy need for heating and lighting as well as the use of artificial light sources is significantly reduced. Moreover, daylight (human centric lighting) has a direct and favourable effect on human beings, for instance on controlling the circadian rhythm.

 

Pioneering solutions in lighting technology

Our experts develop concepts and solutions, which enable us to use daylight more efficiently and ensure users‘ well-being while further reducing energy consumption. In this context, daylight systems are a key factor, simply because sunlight is the most energy-efficient source of light.
