  • Nowadays, global warming and high oil prices were a threat to the survival of the whole human race. One of a solution to respond to these problems is to reduce energy consumption of building. By adopting energy-saving design, the dissemination of low energy building is required. Therefore, to improve energy efficiency while reducing the usage of the design method is necessary to study actively. BIM-based systems applied to buildings, scheduled to be built by reducing the amount of energy reduction technologies can be analyzed. Depending on various design and equipment to set energy savings goals, you can select an alternative. If it is possible to predict the energy efficiency from the initial stage of design and support designing low energy building, we would be able to expect improvement in the economics of housing due to the reduction of energy consumption.

  • Solar energy depends on the altitude and azimuth of the sun, and the amount of energy collected on the slope depends on the latitude of the area being installed. However, since most solar heating systems are fixed to the ground, it is necessary to analyze the optimal installation angle from the early design stage. However, problems arise when energy consumption is not considered together because heating systems are not used in the summer In this study, the optimum installation angles of the solar collectors according to the latitude of the installation area are not simply determined by the amount of energy collected, but because the system is overheated due to climate change or energy usage patterns, And the amount of additional energy input.

  • 전 지구적 기후변화인 지구온난화의 주원인으로 지목되고 있는 온실가스는 공간적으로 주로 도시에서 발생하고 있기 때문에 도시차원에서의 대책이 무엇보다 필요하다. 본 연구는 도시형태와 탄소발생량과의 관계를 분석하여 기후변화에 대응한 탄소배출저감형 도시의 형태를 제시하는 것을 궁극적인 목표로 삼고 있다. 이를 위해, 첫째로 도시형태에 대한 이론고찰을 수행하여 도시공간의 물리적 규모, 이용현황, 활동강도와 관련된 도시형태요소를 선정하였다. 둘째, 서울시를 사례로 전력, 도시가스, 지역난방, 석유, 상수도 사용량 자료를 이용하여 이산화탄소 배출량 지도를 작성하였다. 셋째, 이산화탄소 배출량과 도시형태요소와의 관계를 분석하여 도시공간에서 에너지 사용량에 영향을 주는 도시형태를 밝혀내고, 도시계획 측면에서의 시사점을 도출하였다. 본 연구에서 도시형태 요소와 이산화탄소 배출량간의 관계를 분석한 결과는 실제 에너지 사용량에 기반하여 이산화탄소 배출량을 산정하여 활용하였다는 점에서 기존 연구가 지닌 한계를 극복하고, 사례분석을 통해 구체적이고도 결과를 도출하였다는데 그 의의가 있다.

  • 본 연구에서는 가구의 종류별 가전기기의 사용 패턴을 프로파일링 하여 제시한다. 현재 한국에서는 연간 사용된 가구당 전기기기별 총 사용량은 제시되고 있으나 가구 종류별 전력소비 프로파일 자료는 제시되고 있지 않다. 이런 자료를 수집하기 위해서는 각 가구별로 적어도 일년 이상 각 가구별, 전력기기별 전력사용을 모니터링해야 하는데 개인의 프라이버시 문제로 이런 연구는 진행하기가 쉽지 않다. 본 연구에서는 전력을 사용하는 가정의 종류를 구성원들을 크기 별로 구분하고 각 가정 구성원의 생활패턴을 가정하여 그에 따른 소비패턴 시나리오를 작성하였다. 이것을 바탕으로 통계청의 자료를 사용하여 각 가정별 에너지 소비 프로파일을 작성하였다.

  • Biogas production and utilization are an emerging alternative energy technology. Biogas is produced from the biological breakdown of organic matter through anaerobic digestion. Biogas can be utilized for various energy sectors such as space heating, electricity generation and vehicle fuel. Especially, to be utilized as vehicle fuel, raw biogas needs to be upgraded that is mainly the removal of carbon dioxide to increase the methane content up to more than 95 ~ 97 vol% in some cases, similar to the composition of fossil-based natural gas. Usage of Biogas as a fuel of vehicles have an effect of reducing $CO_2$ emission compared to fossil fuels. Biomethane which is produced by upgrading of biogas is regarded as a good alternative energy and usage of clean energy is encouraged to deal with air pollution and waste management as well as production of clean energy. Recently, biogas projects for vehicle fuel are newly being launched and Korea government have also announced a plan for investment to develop biogas as a transport fuel. In this study, it is aimed to examine the potential feasibility of biomethane as a transport fuel. As a results, the status of biomethane, quality standard, quality characteristics, and upgrading technology of biogas were investigated to evaluate of biogas as a vehicle fuel of transportation.

  • The regulations to reduce energy consumption and carbon dioxide emission in building sectors are being developed and promoted all over the world. However, in Korea, as balcony extension of the apartments has been legally allowed, it became prevalent and resulted in excessive energy consumption. This study derived the possibility of PCM application to the thermal storage wall system through theoretical consideration and investigated the problems occurring when the balcony space has been extended to the diverted space. In addition, this study aims at the possibility of verifying the installation and confirming the cooling energy reduction effect, by conducting measuring tests with the actual installation of PCM applied thermal storage wall system. As a result of theoretical consideration, it is determined that the disadvantages with the existing thermal storage wall system can be complemented by applying PCM, and this study suggests the PCM applied Thermal Storage Wall System. The study was conducted on 1/6 of a miniature inner room of a domestic apartment with 84 $m^2$ of exclusive area. From the results of actual measurements, it is confirmed that the balcony extension structure can gain 11.3% of more calories than the existing balcony structure, resulting in the increase in cooling energy usage. It is determined that the installation of the PCM applied Thermal Storage Wall System may gain 25.2% of less calories to reduce cooling energy usage.

  • Sustainable design is getting to be controversial issue in all industries over the world particularly, in architecture as the amount of energy usage in architecture occupies 40%. Therefore, it is essential to make the standard for the sustainable design. In order to construct the sustainable design, firstly it should be considered that sustainable design elements based on natural resources to increase building energy efficiency is established and classified. The method of sustainable design divides into passive design and active design. Passive design method should be examined with active one simultaneously for more efficient usage of energy. Next, the study is followed how the sustainable design elements is adopted in buildings through the comparison of cases study of domestic and oversea. The result of case study shows similar adoption of sustainable design elements between oversea and domestic. However, the difference is shown in the building orientation and shape and the window size and position in Solar energy as well as high performance structure in Heat energy. These elements are the most significant elements in order to reduce energy load. In oversea, sustainable design is generated by architects, a client, and consultants based on the close cooperation in the beginning of early design phase before deciding building shape and envelope while in the domestic field adoption for sustainable design is conducted after deciding building shape and material. In order to design sustainable architecture more study is necessary in early stage for Zero Carbon and reducing building energy load through relation with specialists, a client and architects.

  • In our country, which imports 97% of the energy consumed, an energy saving policy is required. The price inflation of utility bills is caused by a steep rise in the prices of imported oil. This study aims to solve the difficulties that cause poor environmental conditions for workers in the energy services sector, and especially, to systematize energy consumption reports to manage energy goals by suggesting an example of written energy-saving reports. To this end, this research focuses on energy consumption of target facilities including office spaces in a main building and multi-use facilities of an office building. A system where all employees can participate is structured through the analysis of energy usage in the target buildings.
