Change of the energy used in a house can be separated from LNG, and electric power. The electric power consumption of a house is more increasing than LNG. The interest for electric houses is rising due to energy saving and low carbon emission. Accordingly, the amount of energies and cost are analyzed consumed in a house using cumulative energy consumption. The result of analysis, amount of electric power, is more increase. In comparison, the use volume of city gas is more decrease. In this paper, the use volume of energy resource is analyzed using historical energy consumption data in the past 25 years. In addition, expected electrical power and heating energy is analysed adopting an Electric Residence.

정부과천청사는 에너지 사용량이 많고 절약효과가 클 것으로 기대되어 지난 97년 정부의 국가에너지절약추진 대책의 일환인 ESCO사업 시범 대상기관으로 지정되었다. 사업추진기관인 행정자치부 과천청사관리소는 기존의 사업과는 다른 ESCO사업의 성격으로 인해 시행 이전 많은 논란과 애로사항을 겪기도 했으나, 공공기관 최초로 조명기기 교체를 통한 ESCO사업을 실시해 정부시책에 적극적으로 동참하고 에너지절약에도 앞장서고 있다는 평가를 받고 있다.

Various efforts have been made worldwide to respond to environmental problems such as climate change. Research on artificial intelligence (AI)-based energy management has been widely conducted as the most effective way to alleviate the climate change problem. In particular, buildings that account for more than 20% of the total energy delivered worldwide have been focused as a target for energy management using the building energy management system (BEMS). In this paper, we propose a multi-armed bandit (MAB)-based energy management algorithm that can efficiently decide the energy consumption level of the lighting system in each room of the building, while minimizing the discomfort levels of occupants of each room.

세계적으로 에너지 과다 사용으로 인한 비상사태가 발생하면서 에너지 절감, 그린 에너지에 대한 관심이 증가하고 있다. 특히 블루투스 기반의 네트워크 구성을 통해 중앙 조명 제어가 이루어지고 있다. 그러나 블루투스는 저전력 기술 중 높은 전력을 소모하기 때문에 조명기기가 증가할수록 전력사용량이 증가하기 때문에 저전력을 유지하기 어렵다는 문제점이 있다. 따라서 본 논문에서는 Zigbee 기술을 기반으로 조명기기를 제어할 수 있는 시스템을 설계하였다.

LED illumination has been developed from simple illumination to human oriented multi-functional system depending on the IT convergence trends. Thus, the convergence of IT technology such as various types of sensor and communication functions with application software can make saving of energy, and there are also several needs about the tailor-made illuminations requirements for the diverse users who want to take their own colors, strengths of the light. For the adaption of these kinds of intelligent system illumination, user oriented sensor and control should be possible. The LED lighting control system transmits and receives data via the Bluetooth mesh network and provides functions such as LED lighting control, LED lighting condition monitoring, energy usage monitoring, and energy peak point management. Therefore, in this paper, we suggest wireless communication platform and control system for the LED illumination control. We can expect life extension of LED illumination, and energy saving through this suggested system.

This paper proposes a novel design of auto light control system with high efficiency using RS-485 to save lighting energy in new and existing buildings. The proposed system consists of ALSU(Auto Light Sensor Unit) which is connected with RS-485 to control lighting appliances, ALS(Auto Light Unit), and Hi-FACS which is a monitoring system using communication interface. lighting appliances are automatically controlled by ALSU which detects moving objects. The total system is designed to be controlled by either manual or auto mode by using the ALS. In addition, the monitoring system receives the information on the state of the lighting appliances from ALSU and ALS to control the proposed system We compared the proposed system with the conventional one in functionality and energy saving point of view. Through some experimental results, the proposed system shows better performance in various circumstances.

There has been a significant increase in the amount of research on reducing the lighting power consumption of buildings and also an increasing demand for technological development. Light shelf has been recognized as one of the most efficient solutions to this issue and related researches have been conducted, which have mostly focused on factors related to simple light shelves and are not suitable as an appropriate basis for the design of light shelves. Thus this study aims to establish the proper design basis for light shelves by evaluating the performance of shelves per reflection rate in indoor areas. Power consumption rate and indoor illumination intensity distribution of a testbed built based on actual living conditions were calculated for the performance evaluation, of which the results are as following: 1) Reduction of reflection rate of ceiling and walls caused average illumination intensity in summer, winter and median seasons, and evenness per reflection rate of indoor areas was found to be different in summer, winter and median seasons, making it a necessary consideration for designing light shelves. 2) Calculation of power consumption from lighting control showed that a high reflection rate of indoor areas may be suitable for power consumption reduction, and that reflection rates higher than 80% for ceilings and higher than 75% for walls in terms of the efficiency of researches on the indoor reflection rate and its application would be appropriate. This study is meaningful as the research focuses on light shelves based on considering indoor environmental factors. More studies will be required that consider a variety of factors.
