Light balancing ® : Why ? 1.… Well being of building occupants (comfortable buildings)

Daylight is important for comfort and wellbeing• Research learns that light impacts

our biorhythms (circadian rhythm) and thereby our mood, sleep and performance But Daylight alone is not

sufficient• Electrical lighting is often needed to

see well and perform tasks comfortable and safe.
