AbstractThis experiment was conducted in a mock-up office space in a laboratory. 118 participants worked for a single day under one of four lighting designs. They had no control over the lighting until the last half of the afternoon, when all participants were offered some form of individual dimming lighting control. During this working day they completed a variety of simulated office tasks (not analysed in this report, but to be reported later), as well as completing a number of questionnaires. The experiment was designed to address several research questions with direct relevance to office lighting practice. We looked at preferences for particular lighting designs, particularly designs that provide higher levels of vertical illuminance. We were also interested in whether local/task lighting sources reduced the demand for ambient lighting. We also examined whether providing individual dimming control over luminaires was beneficial.
