최근 다양한 용도로 활용되고 있는 지하철 역사는 새로운 거주공간으로 주목되고 있다. 그러나 지하철 역사는 지하공간으로 인한 폐쇄성 및 사용자의 심리적 거부감을 완화시키기 위해 자연광의 유입이 필요하다. 본 연구는 자연광이 도입된 지하철 역사와 인공조명으로 계획된 역사를 대상으로 조명환경 실태 및 실내 시환경을 평가하였다. 이를 위해, 먼저 선정된 지하철 durg사의 현장측정을 자연광의 영향이 적은 담천공에서 실시하였다. 또한, 사용자를 대상으로 주간에 설문조사를 실시하여 실내 시환경에 대한 조명인식을 평가하였다. 연구결과, 지하철 역사의 시환경에 대한 자연광의 영향 및 출입구 부분에 완화조명이 필요한 것으로 분석되었다. 본 연구결과는 앞으로 보다 효과적인 지하철 역사 조명계획을 위한 기초 활용될 수 있으리라 기대된다.

The present study performed subjective evaluation experiments using slides and scale down models in order to propose guidelines for lighting environment desirable for each behavior in the house. The evaluation measure was composed of 20 mood items and 15 behavior items. As for experiment methods, the slide experiment used SD method, and the scale down model experiment used Scheffe's paired comparison. The results of this study are as follows. 1) Desirable lighting environment for working and talking is active atmosphere. 2) Lighting environment desirable far relaxation is to heighten lighting contrast using candescent lamps and local lights. In other words, active atmosphere, which is desirable for working and talking, is not desirable for relaxation. 3) Lighting for working requires bright illuminance and high color temperature(6000k). 4) Lighting for relaxation requires somewhat low brightness regardless of color temperature. If the light is bright it is better to use lamps of low color temperature. 5) for conversation, bright illuminance is more desirable than dark one, and the most adequate color temperature is 4000K.

In this study, a mock powder room was installed with variable LED lighting environments in order to conduct the experiments. The experimental conditions include luminaire type, illuminance ratio, vertical illuminance and color temperatures. The evaluation methods used were the Semantic Differential Method and a subjective evaluation on activities through observation. The SD evaluation result factor analysis categorizes ideas into three factors: brightness, emotion, and glare. The vertical bracket or the combined luminaire (luminous panel+ Vertical bracket) has better brightness than luminous panel. A vertical illuminance of 500lx is not significantly difference as compared to 600lx, allowing 500lx to be considered standard. The emotional atmosphere is evaluated as being better at lower color temperature. The luminous panel is the best for reducing glare while the vertical bracket is the worst. The best conditions differ according to the illuminance ratio of the luminous panel and vertical bracket. In the subjective evaluation (satisfaction with lighting environment, suitability to activity) the combined luminaire and 4000K received the best evaluation.
