UV-C is an established technology for disinfection. It has been applied extensively since 1910 when it was found to be an effective tool in preventing the spread of disease.
Today, UV-C disinfection technologies are assisting the battle against the current pandemic, Covid-19. More generally, the technology has been proven to bacteria and viruses against which it has been tested, including those causing tuberculosis, influenza, the common cold and SARS.
The European lighting industry is a leader in producing high quality safe UV-C disinfection technologies and products (lamps, lighting fixtures, cabinets and connected systems). They are used to disinfect water, air, and surfaces in industrial, commercial, medical, public and residential environments. UV-C de-activates viruses and microorganisms such as bacteria, moulds, spore, fungi and yeasts by destroying their DNA/RNA.
Many perceive lighting mainly as a driver for energy efficiency and this indeed remains one of the core values for the lighting industry. The now mostly-accomplished transition to LED technology has led to up to 90% savings for European a comprehensive light management year as of 2030 (Lot 37 Ecodesign Lighting Systems <http://ecodesignlightingsystems.
However, the benefits from lighting for the health, well-being, productivity and safety of people are rarely seen as added value. At best, they come for free as part of the energy savings. These benefits received more attention in 2017, when three biologists were awarded the Nobel Prize for helping to explain how the human circadian rhythm works, including how light affects our daily biological cycle.
With the EU Renovation Wave initiative, the discussion must move beyond energy savings to also address healthier buildings, peoples’ quality of life and a lower level of inconvenience. We spend 90% of our time indoors and the quality of our indoor environment has a direct and indirect impact on our health, well-being, and productivity.
