Occupant satisfaction in office rooms equipped with Anidolic Daylighting Systems

This article presents the results of a satisfaction assessment recently carried out amongst occupants of office rooms equipped with Anidolic Daylighting Systems. Questionnaires and complementary personal interviews were used to reveal which typical office lighting related problems are the most annoying to the occupants of the examined offices. The results show that occupant satisfaction within the examined offices is in general very good but that temporary daylight-overprovision and glare can sometimes cause considerable discomfort. The article concludes that window blind configuration, blind control as well as inappropriate handling by the occupants are the main reasons for the encountered problems and discusses different possibilities to deal with them.
