Back to school with Human Centric Lighting!

The brand new Kongsgardmoen School by Kongsberg in Norway opens this August. Here some 230 primary school pupils will have excellent conditions for work and play. Among many modern features they will benefit from particularly good lighting conditions, since the school building is equipped with Human Centric Lighting.

The school has installed luminaires with adjustable colour temperature, so-called "tuneable white” luminaires with LED light sources that can be tuned from cool white to warm white light. All classrooms are equipped with this solution, making this the most comprehensive Human Centric Lighting LED installation date.

Light affects our circadian rhythms
When the children arrive in the morning, they are greeted by a cool white and intensive energy light for the first class. The cool white light regulates the production of stress and sleep hormones in the children’s (and the teacher’s) bodies. The light therefore shifts their daily rhythms forward, making them more active during the day and tired when the night falls. This also has a positive impact on the children’s sleep patterns.

Later in the day, the teacher may activate a focus light when it’s time for concentration tasks such as math tests or writing exercises. A shower of cool white and intensive light increases short term concentration and alertness. When the pupils gather in the front of the class room to listen to the teacher telling a story, a warm white light creates a nice and relaxing atmosphere. These adjustments are made by the teacher himself. The solution also has a standard setting, which is a neutral white, good working light.

Modern luminaires
The luminaires used are modular LED luminaires with diodes that shift the colour according to pre-defined or manual settings. The colour rendering of the light is very high (Ra >90), much higher than the minimum requirements for school lighting. That makes colouring, reading and writing easier and more pleasant. Colour tuning is made easy for the teacher through a wall mounted user panel.
