In commercial buildings such as offices and factories and in outdoor lighting, an integrated and intelligently controlled lighting solution can make a major contribution to climate protection. Artificial lighting consumes 19% of the electricity generated worldwide, a good two thirds of which currently being accounted for by commercial buildings and outdoor lighting. According to CELMA, the European umbrella organisation for manufacturers of luminaires and luminaire accessories, in Europe alone 75% of office lighting is based on inefficient systems.

The Zumtobel Group's brands offer solutions to ensure optimum use of lighting in indoor and outdoor applications. Thorn, Zumtobel and Tridonic use their expertise in the practical application of light and the latest lighting technology to strike a balance between energy efficiency and lighting quality and they work to increase customer awareness of this issue. One important lever for enhancing energy efficiency is the increasing use of modern electronics in artificial lighting. Intelligent control systems, electronic or electronically dimmable ballasts and new, innovative light sources such as LEDs are the most important approaches to boosting energy efficiency.
