CIELOS AND HUMANERGY BALANCE 21 With the Humanergy Balance concept, Zumtobel directs the viewer’s attention to the indis-pensable ecological balance between energy efficiency and lighting quality. People need light to find their way around, to work and to feel at ease. Yet there is a huge difference between different types of light. Daylight is not like artificial light, and a monotonous point of light will create an effect entirely dif- ferent from that produced by a dynamic lighting composition such as the CIELOS modular luminous ceiling. Zumtobel’s wide range of professional lumi- naires and lighting control sys-tems provides the playground to create adequately balanced solutions for a particular appli- cation. CIELOS takes away the airs and graces from the system of the luminous ceiling, making diffuse wide-area lighting an interesting solution for small applications, too. It is ideal for adding an extra emotional and biological component to essen- tially proper lighting solutions, thus making its own contribution towards striking a balance between the economic and ergonomic aspects of lighting.
