This study examines the effect of a daylight dimming control system to improve visual environment in a classroom. Computer simulations were conducted for a variety of daylight conditions. Results indicate that correlation between desktop illuminance by daylight and photosensors signals by daylight were stronger in rear area of space compared to that in areas close to window. This implies that the photosensors installed in rear area might contribute to dimming control performance only in a case that daylight was considered. Overall, the photosensor in rear area failed to keep target illuminance due to strong impact of electric light output. An electric circuit connected to all lighting fixtures in space should be divided to keep target illuminance for rear area, when a daylight dimming control system is applied. The probability for an optimum control performance decreased as the distance from window to desktops increased beyond 5 m. For the area where electric light was stronger than daylight, photosensors should not be exposed to electric light directly so that photosensor signals remain within desirable ranges for optimum control. In addition, more shielding condition should be applied to photosensors installed in the rear area of space.

This study examines the influence of correlated color temperature (CCT) of lamps on visual responses in a small office space. Field measurements and survey were performed in a full-scale mock-up model. Fluorescent lamps with 3500 K and 5000 K color temperature were applied to a recessed direct lighting system. Desktop illuminance levels were 500 lx and 850 lx which satisfy required illuminance for office activities. Eleven subjects participated in the survey. Result indicated that the sensation for brightness was more important than color temperature to feel the distribution of light in space. Under equal illuminance level higher color temperature caused brighter sensation. When 500 lx was used for target illuminance 5000 K color temperature was more effective for office activities, although the sensation for visual comfort was impaired slightly. When 3000 K color temperature was used higher illuminance than 500 lx would be useful to improve visual comfort. Temporary mood was not significantly influenced by color temperature from light in office space. Multiple linear regression implied that visual comfort was significantly influenced by color, brightness and visual stimulation under direct lighting conditions.
