Abstract

This study introduces a new dynamic lighting system exceptional from typical indoor lighting solutions. The main highlights of the tested system are the variable colour temperature and the vertical lighting. Typical modern office lighting is gas tube fluorescent lighting with a fixed colour temperature. The authors used a previously developed dynamic lighting model and tested an experimental lighting panel at workplaces deficient of daylight. The selected building was an atrium type with workrooms facing the inner courtyard being the focal point of this study. The authors presumed workers in such office places to show most improvement under the intervention period. Twelve people participated in the experiment. The subjects’ workplaces were improved with experimental dynamic lighting set-ups and their experience recorded using a questionnaire and a computerized reaction speed test. By the end of the experiment half of the subjects reported having benefited at least to some degree from the dynamic lighting panel. Those people reported having an improved general well-being as well feeling more productive. Analysis of reaction-speed tests also showed some improvement. Keywords: dynamic lighting, natural daylight, colour temperature, atrium.
