The daylight responsive dimming system, which uses daylight and automatically adjusts the light output of electric lighting according to the amount of daylight coming into the indoor luminous flux, a controller (including a control program) for initial calibration and dimming control of the system, and dimming electronic ballast for dimming electric lighting. This research has intended to improve accuracy of system performance by indicating the correlation between control voltage of a dimming electronic ballast and the resulting light output. The commercially available dimming electronic ballasts were tested. Then, through regression processes, the best-fitted equations were derived and compared to experiment results. The ratios of power consumption from different dimming level of electric lighting were measured. Based on such information, energy saving can be estimated when daylight responsive dimming system is applied.

Quality of life is big issue recently Well-being, an idea of looking for healthy and wealthy body or mind in the basis of pro-health, pro-environment spirit, is going to be international trend instead of pursuing fortune and social position From this point of view, this paper investigated a meaning of light in the healthy environment and studied mental and physical effects of light sources, which ultimately affects luminous environment inn the residential areas This paper finally suggested well-coordinated lighting condition, derived from results of relationship between health and lighting, and demonstrated luminous environmental rendering simulation

The dome pendant prismatic luminaire is recently used in commercial and industrial high-bay applications where quality light levels and energy savings are imperative. In addition, it is satisfied with various luminous intensity distrbutions as well as aesthetic designs. Despite these advantages, up to now, most of luminaire designers have only concentrated their attention on the design matters without optical consideration. Even if they know accurate optic a calculation process, it's difficult to produce prismatic luminaire with luminous intensity distribution required in a space, because the design process is made by much trial and error. The process is also required much time to design. μ-GA is one of the improved form of GA, which has been used to find an opimum solution, to reduce iteration and computing resources by using small populations. Therefore, the purpose of this study is to introduce candlepower distribution model of dome pendant prism luminaire and to develope a design algorithm that is able to find an optimum design solution of the luminaire using μ-GA.
광센서 조광제어시스템에서의 광센서 최적 방향성과 위치에 관한 평가 연구
최안섭,정근영 대한건축학회 2003 대한건축학회논문집 Vol.19 No.10
The purpose of this simulation study was to improve the performance of daylight responsive dimming systems. This simulation study was to analyze the followings. ⅰ) correlation between workplane illuminance and photosensor signal ⅱ) comparison between closed loop proportional and open loop proportional control algorithms in the daylight responssive dimming system. This study used DayDim as a simulation software and four different spatial characteristics of photosensors. Each photosensor has different spatial distributions in the existing photosensor, 0 degree, 30 degree, and 60 degree from nadir. Parameters such as sky condition, seasonal changes, azimuth, photosensor location, and different spatial distribution were considered. The results showed proper photosensor position and spatial distrubution determined by the various parameters.

As interests on illumination recently arise all over the world in the point of urban environmental view, people widely use illumination for urban environment as environmental art and making economical profits. In domestic, illumination widely takes part in improving the quality of night urban environment and attracting tourists. However, not like above intentions, since urban plan does not include urban illumination plan as a part and promotes it separately, we had to take the burden of economical loss and environmental quality deterioration. Consequently, this study analyzes space syntax and space using pattern objectively, and applied the Space Syntax Theory, which is used worldly for checking problems in planning, designing of existing cities, and buildings, in order to study the relationship with space characteristic factor and special factors in illumination plan, and then design illumination intensity estimation model through space syntax characteristic factors. Based on above results, this study suggests the methodology of illumination intensity plan using Space Syntax Theory for changes in space syntax or illumination plan for new cities in the future.
RADIANCE 프로그램과 인터넷 환경을 이용한 조명시뮬레이션 시스템 개발
송규동,김지현,최안섭 대한건축학회 2003 대한건축학회논문집 Vol.19 No.4
The prediction of illuminances from daylight and artificial lighting has been an important issue in the field of architecture. Architects traditionally have used scale models or various computer programs as tools for predicting the available illuminance in a building and for visualizing the overall lighting quality of the environment. The program requires accurate modeling of the geometric and photometric properties of a designed environment. RADIANCE is a program developed to aid lighting designers and architects by predicting the lighting levels and appearance of a space prior to construction of a building. The modeling of geometric property is usually conducted by commercially available CAD softwares. The modeling of photometric properties includes material color, texture and/or transmittance, daylight availability, and luminous intensity distribution of artificial light sources. The simulation itself uses backward ray-tracing technique to compute radiance values, which are typically arranged to form a photographic quality image. The purpose of this study is to develop a Radiance rendering system that operates automatically on the WWW environment.

최세리(Se-Ri Choi),최안섭(An-Seop Choi) 한국조명·전기설비학회 2021 한국조명·전기설비학회 학술대회논문집 Vol.2021 No.11
An intelligent system that is being developed from a building-centered to a human-centered is emerged. In order to provide a customized lighting environment for occupants, the exact amount of illuminance in the room must be measured. In this study, a prototype of an IoT sensor for indoor illuminance measurement was developed. The two illuminance meters and the measured values were compared and verified, and the conclusion was drawn that they showed similar values. In addition, the accumulated data was visualized so that it could be checked intuitively.
Case Studies of Assessment of the Indoor Environment Quality for Building Remodeling in Korea
An-Seop Choi,Eun-Taek Lee 한국생활환경학회 2013 한국생활환경학회지 Vol.20 No.6
Consideration of the indoor environment quality conditions and the related physical degradation of the building environment systems is essential in the assessment of a remodeling plan for a building. Based on the results of indoor environment quality assessments, the predicted potential of remodeling actions and the effectiveness of the remodeling interventions can be evaluated. This paper describes the process of assessing the indoor environment quality in commercial buildings. Specifically, the indoor environment quality of the two office buildings and one hospitality facility (hotel) are evaluated as one of the phases in the remodeling process. Thermal comfort and air quality conditions as well as luminous environment conditions are measured, and proposed lighting design options through computer simulation are compared.
