Circadian lighting is good lighting for people’s health, but when we talk about good lighting we need to include the impact of current lighting systems on the planet. So, what does “good lighting” mean?
There are some quality requirements for visual and non-visual effects of light, for example, color rendering, horizontal and vertical illuminance, illuminance uniformity, timing, intensity, color spectrum, etc. Due to people spending 90% of their time indoors, it is very important that artificial light fulfills all these requirements: we need the right light for the right activity at the right time.
To make this possible, we can use technological and digital developments for smart lighting systems, which allow us to enjoy the visual, biological, and emotional benefits of good quality light, as well as minimize the impact on the environment by combining daylight and electric light.
Optimizing lighting system designs with controls will save 20-29 TWh/year in 2030 and 48-56 TWh/year in 2050 [1], note that this value is the current electricity consumption in Portugal [2]. This will have a major impact on the energy consumption and efficiency of buildings, reducing energy costs and protecting our environment. It is becoming more and more necessary to include this kind of system that can help achieve sustainable buildings for people and the planet.
Kumux lighting solution for the planet
At Kumux, we have developed our circadian lighting system thinking about people and the planet. Thus, we also provide a free tool to help buildings visualize their energy saving and lighting performance according to the solution, daytime, and geolocation.
You can compare artificial light, Kumux light, and natural light in terms of color temperature and light intensity during the daytime. And you can make decisions about the energy efficiency in your building.
