Task 50 Highlights 2014Advanced Lighting Solutions for Retrofitting Buildings
February 2015 - PDF 0.21MB
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 Major lighting energy savings can be realized by retrofitting existing out-of-date lighting installations, as new solutions allow a significant increase in efficiency along with highly interesting payback times.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.
