최근 전력수요의 급증으로 에너지 소비를 절감하기 위한 연구가 급부상하고 있다. 하지만 대부분의 사물인터넷 서비스들은 사람의 편의성을 위한 방향으로 발전해왔기 때문에 에너지의 효율화에 대한 고려가 부족하다. 따라서 본 논문에서는 실내 환경 상태 센싱을 통한 에너지 관리 최적화 알고리즘을 제안한다. 에너지 관리 최적화 알고리즘은 실내에 설치된 센서를 통해 환경 정보를 모니터링하고 불필요하게 낭비되는 대기전력을 차단한다. 온도, 조도, 습도 등 센싱된 정보는 주어진 임계값 내에서 사용자 환경에 적응적으로 최적화하여 에너지 소모를 감소시킨다. 성능분석결과 기존의 소비전력환경 대비 LED조명의 경우 하루에 약 180W의 대기전력을 절약하였고, 에어컨의 정우 한달에 약 38,550kW의 대기전력을 절약하여 환경에 따른 에너지 절약효과를 보였다.

The purpose of this study was to figure out the effects of parents' energy conservation awareness and behaviors on young children's environment-friendly attitudes and environmental preservation knowledge. To achieve this, a survey was carried out to 160 kindergarten children and their parents in the farming and fishing communities located in N city, Chungnam through June 10 to June 30, 2013. The results of the analysis were as follows. First, the effect of parents' energy conservation awareness on young children's environment-friendly attitudes showed that parents' environmental preservation awareness and energy conservation awareness had an effect on young children's environment-friendly attitudes. Second, the effect of parents' energy conservation behaviors on young children's environment-friendly attitudes showed that parents' general behaviors and selective behaviors had an effect on young children's environment-friendly attitudes. Third, the effect of parents' energy conservation awareness on young children's environmental preservation knowledge showed that parents' environmental preservation knowledge and energy conservation awareness had an effect on young children's environmental preservation knowledge. Fourth, the effect of parents' energy conservation behaviors on young children's environmental preservation knowledge showed that parents' general behaviors and selective behaviors had an effect on young children's environmental preservation knowledge. As for findings stated above, parents' energy conservation awareness and behaviors had a positive effect on children's environment-friendly attitudes and environmental preservation knowledge. This implies that parents' right energy conservation awareness and behaviors are important to enhance children's positive environment-friendly attitudes and environmental preservation knowledge.

그간 스마트그리드 추진을 위한 법 제도적 기반 마련, 세계적인 대규모 실증사업 추진에도 불구하고 실질적인 성과 확보에는 미흡했다. 그 원인으로는 요금 현실화, 전력판매시장 경쟁 도입 등 핵심이슈 추진 부진을 들 수 있다. 그러나 제주실증사업 등 그동안 추진실적에 대한 평가 분석을 바탕으로 스마트그리드 확산을 위한 사업 추진이 필요한 상황이다.

We suggest improvement direction of energy-saving design based on analysis of current situation in school facilities. School facilities have large area among public buildings. While the number of students is decreasing, the number of school and energy consumption is increasing year after year. School facilities have excellent heat insulation property, but it requires further examination about excessive heat insulation plan. School facilities are using gas heat pump actively for cooling and heating, but has difference in use ratio of ground source heat pump by region. Thus School facilities requires active using of ground source heat pump and BIPV(Building Integrated Photovoltaic System).

Solutions to improve collaborative energy-saving programs were developed as follow; First, the scoring for the selection of the programs between KEMCO and the NGOs' Energy Network needs to be adjusted. Second, solutions were proposed to diversify the network selected to participate in programs and to tighten the network among the participating citizens. Third, improving the compatibility with the targets that are set for the program and raising the program budget was proposed. Fourth, ideas to introduce the final evaluation guidelines for the programs by the network, to improve the convenience of the program procedures. Fifth, developing a manual to inspect energy-saving measures in households, counseling for at-home energy-saving behaviors, sharing search programs such as financial support and home repair, introducing a program energy-saving APPs.

에너지효율향상 및 에너지절약에 대한 다양한 이슈들이 만들어지고 있는 가운데 자연스럽게 ESCO사업에도 많은 관심이 쏠리고 있다. 하지만 관심이 높아지고 있는 만큼 ESCO투자사업 효과성과 ESCO에 대한 불신의 문제가 많은 우려를 낳고 있는 것도 현실이다. 이에 ESCO협회에서는 '시장친화적 ESCO발전방안 연구용역' 발주를 통해 민간차원에서 ESCO사업의 효과를 분석하고, ESCO업계의 측면에서 ESCO의 발전방안을 도출할 수 있는 방안을 마련하도록 했다. 본 문에서는 '시장친화적 ESCO발전방안 연구'의 요약문을 통해 ESCO사업의 성과와 앞으로의 ESCO발전 방향에 대해 살펴보고자 한다.

The purpose of this study is to predict the performance of an indirect evaporative cooling system, and to evaluate its energy saving effect when applied to the exhaust heat recovery system of an air-handling unit. We derive the performance correlation of the indirect evaporative cooling system using a plastic heat exchanger based on experimental data obtained in various conditions. We predict the variations in the performance of the system for various return and outdoor air conditioning systems using the obtained correlation. We also analyze the energy saving of the system realized by the exhaust heat recovery using the typical meteorological data for several cities in Korea. The average utilization rate of the sensible cooling system for the exhaust heat recovery is 44.3% during summer, while that of the evaporative cooling system is 96.7%. The energy saving of the evaporative cooling system is much higher compared to the sensible cooling system, and was about 3.89 times the value obtained in Seoul.
