The improvement of perspectives on dark and limited underground space could be an important factor in successful underground space development. Current trend in the apartment underground parking lot requires not only quantitatively energy efficient design and operation, but also qualitative improvement of the space. For this, we need to consider two factors: Firstly, to understand the characteristics of the fluorescent lamp. Secondly, to improve the uniformity ratio of illuminance. In winter season, a way to keep the uniformity and a method not to lower the indoor illuminance level by cold ambient air. Therefore, a change in interval and arrangement of the lighting fixtures is required. Also, in their operation, current time-fixed control method needs to be changed into the control that method considers the use pattern.
