So many energy saving strategies to realize the low energy house are proposed in these days. Even if the energy saving performances are similar between the strategies, the costs are in abroad ranges. Therefore, the application of the energy saving strategies should be based upon two considerations; one is energy saving performance and the other is the cost. In this study, the decision making method for application of the passive design technologies in the design stage of the low energy apartment house are suggested. By utilizing the result of this study, practitioners can make an effective design alternatives which solve the conflicted values; energy saving and cost.

Enhancement of exterior's insulation performance like wall or window etc. is general way for building's energy efficient and thermal performance. But exterior's opening plan is important for minimizing the energy consumption and heat loss. In this paper, energy saving rate will be analyzed and compared considering the window area's rate and window's SC(Shading Coefficient) in a apartment with Building Energy Efficiency Rating System's evaluation tool. In the process of evaluation, energy saving rate is measured at each stage of the window area's rate from 20% to 60% every 10% term and the shading coefficient value from 1.0 to 0.6. As a result of this research, energy saving evaluation could not be measured exactly with existing evaluation tool. Accord this research, Building Energy Rating System's evaluation range is needed to be broaden for exact evaluation of energy saving rate.

Solar hot water system produces hot water using solar energy. If it is not used effectively, overheating occurs during the summer. Therefore, a lot of research is being done to solve this. This study develops thermoelectric power module applicable to solar hot water system. A thermoelectric material can directly convert thermal energy into electrical energy without additional power generation devices. If there is a temperature difference between high and low temperature, it generate power by Seebeck effect. The thermoelectric module generates electricity using temperature differences through the heat exchange of hot and cold water. The water used for cooling is heated and stored as hot water as it passes through the module. It can prevent overheating of Solar hot water system while producing power. The thermoelectric module consists of one absorption and two radiation part. There path is designed in the form of a water jacket. As a result, a temperature of the absorption part was 134.2°C and the radiation part was 48.6°C. The temperature difference between the absorption and radiation was 85.6°C. Also, The Thermoelectric module produced about 122 W of irradiation at 708 W/m 2 . At this time, power generation efficiency was 2.62% and hot water conversion efficiency was 62.46%. 태양열 온수 시스템은 태양에너지를 이용하여 온수를 생산한다. 하지만 여름철 같은 경우 과열로 인하여 충분히 사용되지 못하고 있어 이를 해결하기 위하여 많은 연구가 진행되고 있다. 본 연구는 태양열 온수 시스템에 적용이 가능한 열전발전모듈을 개발하는데 있다. 열전발전은 특별한 설비 없이 태양열로부터 전력 생산이 가능하다. 태양에너지로부터 획득한 열을 흡열부로 보내고 냉수를 방열부로 보내어 그 온도차를 이용하여 전력이 생산된다. 열전발전모듈의 흡열부와 방열부는 워터자켓 구조로 설계, 제작하였다. 열전발전모듈의 성능시험을 위해 태양열 온수시스템에 적용하여 성능시험을 한 결과, 일사량 708 W/m2에서 흡열온도 134.2℃, 방열부 온도 48.6℃, 온도차 85.6℃ 일 때, 122W의 전력을 생산하였다. 또한 발전효율은 2.62%, 난방효율은 62.46%로 나타났다.

In this paper we made energy consumption units of glass curtain wall type apartment and general apartment in Busan metropolitan city and compared energy consumption characteristics by building envelope. The monthly electricity consumption units of general apartment were shown in the range of 1.16~1.51kWh/m<SUP>2</SUP>·mon which were indicated higher value in January, February, August and September with little variation. On the other hand, in case of glass curtain wall type apartment, monthly electricity consumption units were represented in the range of 1.91~7.07kWh/m<SUP>2</SUP>·mon with significant fluctuations monthly, which were outstandingly high in July, August and September. The monthly city gas consumption units of general apartment were found to be in the range of 1.79~18.07MJ/m<SUP>2</SUP>·mon, while glass curtain wall type apartment were with in 0.94~ 19.91MJ/m<SUP>2</SUP>·mon. City gas consumption units from December to March were shown highly in both type apartments. The monthly energy consumption units of general apartment were found to be within 14.23~30.69MJ/m<SUP>2</SUP>·mon, while glass curtain wall type apartment were within 24.49~68.9MJ/m<SUP>2</SUP>·mon. Energy consumption units of glass curtain wall type apartment were suggested 4.84 times higher than those of general apartment.

South Korea having military power within the 10th in world ranking is the biggest single institution among public institutions in Korea and comprises force of over seven hundred thousand soldiers. However, outworn equipments and efficiency problem have issued. So, this study is to search the distribution state of new-renewable energy and to analyze application plan on the basis of interview with a official in charge in military. Analysis process is the first, classify surveyed military facilities into troops and the geographical factor. Second, classify a scale and type of facilities that new-renewable energy is supplied. Third, find consideration facts on the basis of interview with a official in charge. On the results of the survey, new-renewable energy applied to the military facility is photovoltaic, solar heat, wind power and geo-thermal energy. Also, divide military into the army, navy, air force and marine, visit 14 units and analyze the official's opinion. This study will deduce LCCA(Life cycle cost analysis) considered expenses for the installation and maintenance, and will be basic research that suggest an appropriate new-renewable energy model in military.
