Lighting accounts for approx. 19% (~3000 TWh) of the global electricity consumption. Without essential changes in
policies, markets and practical implementations it is expected to continuously grow despite significant and rapid technical improvements, like solid-state lighting, new façade and light management techniques. With a small volume of new buildings, major lighting energy savings can only be realized by retrofitting the existing building stock. Compared to existing installations, the majority of new solutions allow a significant increase in efficiency – easily by a factor of three or more – going along with highly interesting payback times. However, lighting refurbishments are still lagging behind
compared to what is economically and technically possible and feasible.

Lighting accounts for approximately 19% (~3000 TWh) of global electric energy consumption. Without essential changes in policies, markets and practical implementations, it is expected to continuously grow despite significant and rapid
technical improvements like solid-state lighting, new façades and light management techniques. Major lighting energy savings can be realized by retrofitting existing out-of-date lighting installations, as new solutions allow a significant increase in efficiency along with highly interesting payback times. However, lighting refurbishments are still lagging behind compared to what is economically and technically possible and feasible.

Lighting accounts for approximately 19% (~3000 TWh) of the global electric energy consumption. Without essential changes in policies, markets and practical implementations, it is expected to continuously grow despite significant and rapid technical improvements like solid-state lighting, new façade and light management techniques. Major lighting energy savings can be realized by retrofitting existing out of date lighting installations, as new solutions allow a significant increase in efficiency combined with highly interesting payback times. However, lighting refurbishments are still lagging behind compared to what is economically and technically possible and feasible.
