광천장 사무 환경에서의 행위별 적정 조도·색온도 도출

The system lighting integrated with IoT(Internet of Things) technology was preferentially applied in office environment, and people are expecting the system lighting to be in harmony with the large area lighting(luminous ceiling) of high uniformity factor as future lighting. The research on this issue should be developed into the user-fiducial compatibility research, and as the premise thereof, required is the examination from various angles like an occupant’s behavior, emotional satisfaction and age-specific characteristics, etc. This study, targeting the large area lighting office environment, deducted optimum lighting environment by age and behavior. The study results are as follows: 1) In case of the glare and preference, the age-specific difference was found to be insignificant, but to be in a different distribution in case of visibility. The study result indicated that the group in their 40s～60s demanded higher illuminance than the group in their 20s～30s; therefore, it’s necessary to do differential design according to occupants’ age-specific distribution. 2) The optimum scope by behavior was classified by color temperature, but the lighting design standard based on the visual-sensory scale for all behaviors(computer work, reading, writing in general) was found to be 4000K, 700lx. The standard for this was found to be higher than KS illuminance range(public facility reading standard and office general standard), and re-examination of KS illuminance range is required.
