Abstract

This paper presents field measurements on daylighting and electric lighting with dimming controlled systems for a small office in Seoul, Korea. And the main purpose of this study is to provide the evaluation data of lighting energy performance when a dimming system is installed. For the performance evaluation, the mock-up room(3.6x7.2x2.6[m]) was used for the actual test. The results of this study were as follows; 1) The correlation between daylight illuminance at a workplane(Ed) and the photosensor signal(Sd) was an important factor affecting the performance of daylight responsive dimming system, 2) The mock-up office space gained a sufficient workplace illuminance of 579[lux] with the dimming control system 3) About 53[%J of monthly lighting energy could be saved using the dimming control system.

본 연구에서는 소규모 사무공간을 대상으로 주광과 인공조명의 성능 평가를 위한 디밍제어 시스템의 실험을 실시함으로써, 사무소 건물의 조명에너지 절약을 도모할 수 있는 성능 평가 자료를 제시하고자 한다. 본 연구에서는 성능 평가폭 위해 Mock-Up Room(3.6${\times}$7.2${\times}$2.6(m))을 사용하여 측정하였으며, 연구 결과는 다음과 같다; 1) 주광작업면조도와 센서조도간의 상관관계는 디밍 시스템의 성능에 영향을 미치는 중요한 요소이다. 2) 디밍 시스템을 적용한 본 실험에서는 주광과 인공조명을 포한함 총 작업면조도는 월평균 579[lux], 월간 에너지 절감율은 약 53[%]로 나타났다.
