We helped prove that biodynamic light helps the elderly

The University Center for Energy Efficient Buildings of CTU participated in a unique scientific experiment. As part of it, biodynamic lighting was installed in the Home for Seniors in Beroun and its effectiveness on the physiological and psychological functions of clients and care staff was subsequently evaluated. The results showed that the tested special lights are a significant contribution to improving the quality of human life.

The CTU Healthy Lighting Platform UCEEB collaborated with Spectrasol and the National Institute of Mental Health (NUDZ) on a pilot application of biodynamic lighting and subsequent experimental research. "We changed the lighting in six rooms, including the hall and bathrooms, in the main dining room, in two nursing rooms, in the creative workshop and in the main corridor. In cooperation with experts from CTU, it was possible to design lighting for daytime lighting that is spectrally close to natural light from the sun, as well as evening lights that have a low content of the blue component of the spectrum as in the sun at sunset, and a third night lighting system, where in this time the biologically toxic blue component is completely eliminated, such as in the light from a fire. While the full-spectrum revitalizing daylight supports cognitive performance and good mood, the evening light, thanks to the innovatively solved distribution, is abundantly sufficient for the visual orientation of clients and staff," explained Hynek Medřický, an expert in lighting systems from Spectrasol.

"Objective measurement of light parameters in the space as well as subjective evaluation using questionnaires confirmed the improvement of the visual comfort of the residents of the nursing home. In particular, the night orientation lighting, which brings users more confidence when moving in the space at night, was evaluated positively," added Lenka Maierová from CTU UCEEB.
