The purpose of this study was to test the effectiveness of the light-shelf system combined with IT to save lighting energy in resident space. According to the multiple variables that affected intensity of illumination, various experiments were designed and conducted. The main findings of this study were following: (1)the optimal level of light-shelf system was formulated which met the appropriate range of intensity of illumination in living-room; (2)although the mixed light-shelf system indicated a high performance, it could often provide discomforts to residents according to the degree of exposure; (3)artificial lights using light-shelf system combined with IT showed a higher effectiveness than those using fixed light-shelf system displayed. This study provided initial information of light-shelf system formative processes that could contribute to the lighting energy diminution. Future studies should focus more on multiple approaches regarding different types of resident space planning.

The purpose of this study is to identify current condition of night lighting plan for the outdoor space in an apartment complex and to examine how residents perceive that environment. For this purpose, considerations and standards for safe and agreeable night lighting environment were examined through literature study. And a field study to determine the current state of the night lighting environment was conducted, and finally a survey was executed to find out residents' satisfaction, requirements and consciousness on that lighting environment of apartment complex. Findings of this study can be summarized as follows. Firstly, most standards for night lighting environment focus on the urban environment as a whole, so they have very few clear standards exclusive for the outdoor space of the apartment complex. Secondly, most of outdoor spaces surveyed in this study have met the basic illumination standard, but some spaces had parts where lights were off or out of order forming dark zones, and in some parts lights were screened by trees causing shades, poor safety and a narrowed sight. Thirdly, residents had interest in the night lighting environment of the outdoor space, but they were not fully satisfied with that environment. Fourthly, residents were negative about such factors of the environment as safety, convenience, recognition and aesthetics. These factors should be reflected in planning and improving the night lighting. It is expected that this study provides basic information necessary to plan safer and more agreeable night lighting, and to satisfy the residents' need for liveable apartment complex.

Besides its basic function of illuminating a space, lighting can greatly affect the efficiency of a space when an advanced technology and planning, together with the effects of various presentations, are applied to lighting. A lighting plan suitable for maximizing the efficiency of a space will only be made feasible by considering the location of a space and the characteristics of the lamps to be used. In particular, the lighting plan for a space with a special function requires prior investigation and analysis of that space. In this study, the feasibility of a lighting environment for the tunnel of a radioactive waste disposal facility is investigated via a prior lighting design and simulation, which take into account the spatial characteristics of the tunnel. For this study, the use of fluorescent induction lamp is suggested, and the standards of lighting plan and structure are followed depending on the location of each segment of the tunnel. Then, a simulation analysis is conducted to investigate the feasibility of the plan.

Modern consumers tend to show value-oriented, image-centered, individualized, and emotionalized consumption behavior, not the consumers who are simply provided with products. Department store industry actively corresponds to the changing consumption behaviors of consumers and pays attention to Visual Merchandising(VMD) as a strategy to visually differentiate stores and sales environments. This study shows 6 parts of effective VMD; presentation of product, product display, color composition, planning of lighting, POP and sign display.

Factors which affect largely the economics of lighting system, are initial installation costs, maintenance costs, energy costs as so on. In these costs, maintenance cost, lamp replacement labor cost, luminaire cleaning cost et al. so the economics of lighting system are evaluated different by maintenance planning. It is important to evaluate which lighting system would be economically advantageous in a initial design. In this study, the importance of maintenance factor is verified by the evaluations of the economics of lighting systems while maintenance factor is varied composition factors in ZCM which is used to calculate the average illuminance.

The research aims at providing data needed for planning the lighting of a study room by comparing the lighting environments of study rooms for urban and rural juveniles. The subject of the research was 300 students in middle schools in Daegu and Checngdo-gun, Gyeongsangbuk-do (Daegu 150 houses and Cheongdo 150 houses), and their study rooms were examined. The following is the result of the research. First, rural students stayed more time in their study room than urban students. The task that rural students (studying) and urban students (studying and using computer) all did in their study room was mainly visual work Second, although the sizes of rural study rooms were bigger than those of urban study rooms, urban study rooms had more light sources than rural study rooms. In the rate that of having a task lighting, the city(87.1[%]) was higher than the country (45.7[%]). However, the rate of using a task lighting was lot high in both the city and the country. Third, the result that compared the average values of illuminations on desk planes was that the average value of the city was 3.4 times higher than that of the country. Also, the average value of the country did not meet the standard illumination of Korean industrial standards (KS). In particular, it did not reach the lowest standard. The result is related with that only 52[%] of students who had a task lighting used it. Finally, the satisfaction of lighting environment in the city was generally higher than the country. Especially, although the country had a low illumination, the user showed a high satisfaction. It indicates that people living in the country need to understand about the needs of illumination.

There are high recognitions on the importance of comforts in Elderly living environment, but the circumstance is that studies on seniors facility space itself are approached only in planning level, and studies on lighting environment which is significantly associated with the comfort in the indoor environment of seniors where they actually spend the majority of their time are not that active. This study was intended to deduce cozy bedroom environment to which existing elderly care facility can be improved by using light shelf the lighting system with the advantage of being able to serve both as building sun visor and lighting window simultaneously in order to analyze the interior environment of bedroom space of elderly care facility the indoor space where the aged spend the majority of their life and examine the directions for the improvement of existing building lighting system through remodeling and renovation. In this study, lighting performance analysis was done in a way that the windows of the bedroom unit in existing facility were set in southbound direction based on two standard types and were put under initial simulation with the use of Autodesk Revit 2011, and after the simulation results were converted to Green Building Studio gbXML file to be used in ECOTECT, Daylight Autonomy a dynamic simulation and static natural lighting simulation the existing method of calculating daylight factors were deduced through Ecotect Analysis 2011. In conclusion, exiting standard model was found in such a condition that the daylight factors for both type A and type B were above 5% the proper standard value, and required improvement. In case light shelf the natural lighting system was attached, the daylight factor was improved to proper standard value for type A, and also was improved above existing facility for type B.
