AbstractA pilot case study was conducted to obtain first-hand knowledge of the operating characteristics of a commercially available daylight-linked dimming system. The test area consisted of an open plan south-facing office area with an adjacent reference area. Excluding an initial set-up and adjustment period, monitoring was conducted for eight months. Significant savings were realized in the zone closest to the windows. Some additional energy was saved through the use of the more efficient dimming ballasts rather than regular ballasts. This advantage could be offset, however, by higher line currents and poor power factor. Although the particular aspects of the site limit general use of the results, the issues presented should be considered when evaluating the performance potential of any photoelectric dimming system.
