Advanced Lighting for Retrofitting Buildings

Advanced Lighting Solutions for Retrofitting Buildings


Lighting accounts for approximately 19%, i.e. 2900 TWH, of the global electric energy consumption. Projections by the IEA show that if governments only rely on current policies, global electricity use for lighting will grow to around 4250 TWh by 2030, an increase of more than 40%. Due to the world’s growing population and the increasing demand for electrically driven services in emerging economies the increase will occur despite constant improvements in energy efficiency of lighting systems. One recent study indicated that investments in energy ‐ efficient lighting is one of the most cost‐effective ways to reduce CO2 emissions.

Research and developments in the field of energy efficient lighting techniques encompassing daylighting, electric lighting and lighting controls combined with activities employing and bringing these techniques to the market can contribute significantly to reduce worldwide electricity consumptions and C02 emissions. These activities will therefore be in line with several different governmental energy efficiency and sustainability targets.
