Samenvatting

Dynamic lighting is designed to have positive effects on wellbeing and performance. In a field experiment we tested whether these effects are detectable and stable over time when employed in actual work settings. This 2-year study consists of two tranches, one following a monthly alternating experimental design, the other a yearly alternating one. This paper reports on the first tranche. In a fully counterbalanced design, office workers experienced dynamic or static lighting according to an a-b-a scheme over 3 consecutive periods (N=142, 90, and 83). Questionnaire data suggest no significant differences for need for recovery, vitality, alertness, headache and eyestrain, mental health, sleep quality, or subjective performance, although employees were more satisfied with dynamic lighting. Yet it is too early to discard the hypotheses and claims made about dynamic lighting altogether. Its effects may still emerge in environments with limited daylight, over a longer time period, or when more pronounced or differently shaped lighting patterns are applied.
