Lighting Metropolis, Green Economy: The lighting of the future is tested in Greater Copenhagen
In recent years, interest in how light affects living beings has increased significantly. Nobel laureates have shown that natural sunlight helps us optimize our physiology for the different phases of the day, and this has led to various tests of sunlight-like lighting indoors. A related topic is how people are affected by being exposed to light at night. In the Lighting Metropolis project, municipalities and regions in Greater Copenhagen have tested how LED lighting can be used to save energy and create healthier lighting environments.

Lighting Metropolis is an EU project, led by Innovation Skåne and Street 21. In the project, the goal is to create better and correct lighting, both in the form of adapted lighting for people in different situations and in the form of energy savings. A number of sub-projects have been carried out and have also involved researchers. The project has also worked by gathering available knowledge, by inspiring and networking and collaboration. The project was completed in 2022. The results of the lighting projects made will also be reported, but already now it is clear that there are great opportunities to improve human health through proper lighting.
The main objective of the project has been to reduce energy consumption (the target was 5,700,000 kWh/year) and this has been achieved. The transition to LED lighting in the project has resulted in a total energy saving of 7,251,446 kWh, which corresponds to the electricity consumption of 1800 households. This is an average energy saving of 61% for all sub-projects where in some cases they have managed to save more than 90%.
In addition, the participants have investigated various aspects of light quality from LED lighting, and this work is described in detail in the final publication. It is emphasized that high quality of light is important because we stay indoors in artificial light for much of our waking time, and thus do not stay in natural daylight.

An important part of the project regarding indoor lighting has been to investigate the benefits of circadian lighting in various care units and care homes in Skåne. The idea is to amplify the true daylight that enters through windows and control both color temperatures and intensity of indoor lighting so that it is consistent with the sunlight and can amplify the benefits of sunlight. The project has invested in circadian lighting in two care units at Helsingborgs lasarett, a psychiatric ward at SUS in Malmö and a nursing home in Klippan. On the Danish side, more work has been done in school environments, for example in Ballerup and Roskilde. In health departments, the expected result has been that the light will create a better feeling among patients and fewer sick leave and lower staff turnover.
