(Day)light in office buildings has already been proven to be a beneficial contributor to
health. However, people’s perception of the physical light environment deviates
significantly from objective measurements. Large differences between user’s perception
and objective light parameters, such as illuminance level or daylight contribution, could
lead to people interfering with the automated lighting system which then may not be able
to deliver the intended employee’s health benefits. This study found deviations between
objective and subjective measures. In addition, correlations between daylight/electric light
ratios (DL/EL) and self-reported satisfaction with lighting or self-reported general health
were found to be not always statistically significant throughout the duration of the
experiment. Further research should focus on the differences between subjective and
objective light parameters and potential mediators between office lighting and occupational
