Technology has been viewed at various stages of civilization as leading to future progress. The building, its services systems and management of the work process all contribute to the well-being of people within an organization. Productivity relies on there being a general sense of high morale and satisfaction with the workplace. Now buildings are considered as providing a milieu for human creativity. Flexibility, adaptability, service integration and high standards of finishes offer an intelligence threshold. Building Automation System(BAS) - controlled lighting systems may offer incremental energy saving. Conventional Lighting control systems often control equipment in a single room or over the limited area, because they are centralized control systems, which means that all the controlled circuits must be wired to a single control panel. The computers used by these systems are typically dedicated microprocess that perform only lighting control functions. By comparison, modern Building automation systems are distributed control system, which means that their computing hardware and software are distributed as a network that microprocessor-based control modules and standard PC. PLC(Programmable Logic controller) is extensible virtually without limits, so that all the lighting in a facility can be controlled by single, unified system - the same system that also can control and monitor the building's HVAC, security, and manufacturing processed, elevators, and more. A Building automation system can control light using schedules, manual controls, occupancy sensors, and photosensors, either singly or in combination. Building Lighting control and monitoring system will be for a energy saving and efficient building management system.

LED 조명은 IT융합 시대로의 진화에 따라 단순조명에서 인간중심화 및 다기능화 시스템 조명으로 발전하였다. 이로 인하여, 다양한 센서기능, 통신기능 등의 IT기술과 응용소프트웨어와의 융합을 통하여 사용 환경 변화에 따른 조명 제어로 에너지가 절감되고 빛의 세기와 색 조절 등 다양한 사용자 중심의 맞춤형 조명이 요구 되고 있다. 이러한 지능화된 시스템 조명을 위해서는 사용자 중심의 센서 적용 및 제어가 가능해야한다. 따라서 본 논문에서는 LED 조명관제를 위한 유무선 통신 플랫폼 및 관제시스템을 제안하고자 한다. LED 조명 관제 시스템은 Bluetooth 매쉬 네트워크를 통해 데이터를 송수신하며, LED 조명 제어, LED 조명 상태 모니터링, 에너지 사용량 모니터링, 에너지 피크점 관리 등의 기능을 제공한다. 제안한 유무선 통신 플렛폼과 관제시스템을 통해 LED 조명의 수명 연장 및 에너지 절약 등이 가능할 것으로 기대된다.

Since the first lighting light source was invented, lighting has turned into superior-quality lighting considering the amenity of occupants, and the characteristics of a light source has developed rapidly. So this research confirmed the lighting performance of a dimmer control system and an ON-OFF control system via the existing light source, and analyzed the basic lighting environment of Permanent Supplementary Artificial Lighting of Interiors(PSALI) through the physical comparison and evaluation of a LED lamp substituted for a fluorescent lamp used in a dimmer control system, showing that the lighting physical quantity characteristics of an ON-OFF control system and a dimmer control system are similar to each other and that they are effective in terms of energy saving. Besides, it was shown that introducing a LED light source to a dimmer control system improves lighting environments and largely reduces energy consumption.

This study examined the P Church in the Large chapel and S Church in the midium chapel were Analyzed to the installed stage broadcast lighting system. As a result of the installation of lighting equipment of LED class in P Church in the Large chapel, it provided clearer image and did not have shadow. While tungsten halogen illumination was very hot and heated to be preaching, LED was not heated so the pastor was very comfortable for preaching. S Church in the Midium chapel due to low ceiling height using LED lighting musical, theater and possibly were directed. If a similar structure of Dae-Hak Street theater to replace the existing fixtures by LED lighting, rendering effective and energy saving effect is thought to have much effect.

In the normal office building, the energy consumption to maintain the reasonable intensity of illumination for the work by using the artificial illumination occupies 30% or greater of the whole building electric energy consumption. If the dependability of the artificial illumination is dropt by positively using the natural lighting from the outside, the large amount of electrical energy can be saved, in addition the more nice visual environment for work can be created. Daylight is lighting source that most closely match visual response of the human, because sunlight and skylight achieve the harmony. For this reason, the daylight of small amount than amount of the artificial lighting source also can give the same effect in work activities of human. In addition, if there is daylight at the window of the building, the energy can be saved by controlling the artificial lighting. In this paper, in the building using the photovoltaic power generation analyze the correlation between the amount of energy generated by photovoltaic and indoor illumination and this was proved through the simulation with Relux 2010. In addition, the amount of daylight inflow in the room and distribution was drawn by the equation and the ratio for the sectional dimming control of each lighting equipment was predicted and the energy saving amount according to this was calculated. As a result, the indoor illumination was satisfied with recommended illumination value of the office and consumption power could be reduced approximately with 20~70%.

본 논문은 사용자의 장애 환경에 맞추어 장애 환경설정을 이용함으로서 조명 이용의 편의성을 향상시키고 에너지 절약을 위한 지능형 조명시스템에 관한 연구이다. 장애 환경은 조명의 점등이 원활하지 않은 상태를 의미하는 것으로서 이를 해결하기 위한 방법으로 원격제어 방식이 요구된다. 원격제어 방식은 스마트폰, 움직임 센서, 타이머를 이용하여 조명을 점등 한다. 스마트폰과 움직임 센서는 이벤트를 감지하였을 때 원격에서 조명 시스템으로 이벤트 발생을 전송하고 이벤트를 수신한 조명 시스템은 램프를 전등한다. 조명 사용자의 설정 환경에 맞추어 조명을 제어함으로서 사용시간을 조절하고 점등 조작을 감소하여 에너지 절약을 실현한다. 제안 기법을 적용하여 조명시스템을 설계 및 구현하여 실험 결과 편의성이 향상 되었고 최적화된 점등으로 약 13.5w/h 정도 에너지가 절감된다.

According to the recent report, the lighting energy consumption of commercial buildings reaches to $30%\sim40%$ of the total energy consumption. It is more than that of cooling & heating energy consumption and it is the major target of energy-saving policy. It is obvious that they are interested in natural lighting device such as Light-shelf for the purpose of raising the lighting energy-saving efficiency. In most of highly developed countries, a thorough study on Light-shelf makes it possible to propose a practical plan while at home there leaves much to be desired to study a guiding principle of optimum plan in spite of its efficiency based on experiments using scale4 model and analysis of simulation. Aiming at making an optimum plan of Light-shelf suitable for the domestic situation, this study is worked by experiments using light-shelf and analysis of variables using illumination program. The experiments is to analyse the efficiency of Light-shelf on condition of the sky and the analysis is to make the simulation using illumination program. This study is composed of 1) the analysis of light with some variables such as presence of light-shelf and degree of angle using 1/2 scaled model 2) making the simulation using Lightscape, illumination program, In brief, concerning presence of light-shelf, it causes little difference in its efficiency in the overcast sky, whereas it decreases an illuminance of window side and provides inner side with the light, which decreases the ratio of the maximum to the minimum inner illuminance and makes the inner of illuminance to range evenly in the clear sky. On degree of angle, as the daylight increases in proportion of degree of angle, the ratio of the maximum to the minimum inner illuminance decreases, which makes it possible to increase the proportion of inner daylight.
