In the beginning of the questionnaire, LESO-SEB occupants were asked to state their agreement with the statement “In general, the lighting in my office is comfortable”. Average agreement with this statement was found to be 87%, a comparably high percentage: Average agreement with the same statement in the US had previously been found to be only 70% [9]. 78% of the 23 study participants think that the lighting within their ADS-equipped office is better than the lighting in other offices where they have previously worked. 22% judge the lighting comparable to their former offices. None of them feel that the lighting at the LESO-SEB is worse compared to the lighting in previous offices.
