  • 한국은 OECD 국가 가운데 교토협약에 따른 온실가스 감축의무를 갖지 않는 몇 안 되는 국가이다. 한국은 자발적으로 2015년부터 강력한 온실가스 감축을 단행하기로 하였다. 정부의 현정책들은 온실가스 감축에 따른 경제성장의 저하를 감안하지 않고 있어, 이 정책의 지속성이 제약된다. 이 점에서 산업의 부문별 특성을 감안한 감축전략이 더욱 친환경적 전략이 될 수 있다. 이 연구는 혼합단위를 사용한 에너지 산업연관분석에서부터 온실가스 배출에 유의미한 산업을 선정해 분해분석을 함으로써 유용성을 검증하였다. 유의미한 산업은 '유기화학기초제품군'과 '시멘트 및 콘크리트 산업'을 대상으로 삼았다. 변이는 에너지 소비, 생산, 공정개선 그리고 신시설의 도입 효과로 구분해 실증되었다. 이 연구에서 디비지아 분해분석 결과치들이 부분적으론 불안정적 시계열 패턴을 보였으나, 전체분석 과정으로 보면 일련의 분석과정은 대상산업의 에너지 사용과 온실가스 배출의 행태를 이해하기에 충분한 정보를 제공하였다.

  • 본 논문은 기술-제도 복합시스템을 활용하여 우리나라의 전력 산업이 현재의 탄소의존 경로에 이르게 된 다양한 원인들을 역사적으로 분석하고, 우리나라 전력산업이 탄소고착에서 벗어나 지속가능한 체제로 전환할 수 있는 가능성에 대해 평가하였다. 분석의 결과 우리나라 전력산업의 탄소고착을 강화시키는 요인들은 시장, 기업, 소비자, 정부측면에 고르게 분포되어 있는 것으로 드러났다. 경제성에 근거한 대규모 발전설비를 선호하는 정부정책과 저렴한 전기요금제도, 요금 인상을 엄격히 억제하는 물가관리 시스템, 여름철과 겨울철 전력수요 급증, 탄력적인 요금제도의 부재, 유연탄과 천연가스 설비의 확대 등이 그것이다. 반면 원자력발전과 스마트 그리드를 제외하면, 탄소고착을 완화시키는 요인들은 주로 환경관련 법률이나 신재생관련 법률이다. 전력산업의 탄소배출이 전원구성에 의해 가장 큰 영향을 받고, 우리 경제가 제조업 기반의 수출 위주이며, 산업과 상업부문의 전력소비가 총 85% 이상이라는 점 등을 고려할 때, 우리나라 전력산업이 이른 시일 내에 탄소고착에서 벗어날 수 있을 가능성은 그리 높아 보이지 않는다. 따라서 우리나라 전력산업이 탄소고착을 탈피하기 위해서는 시장, 기업, 소비자, 정부 차원에서 복합적인 개선 노력이 필요하다. 우선, 시장측면에서는 주요국처럼 독점을 완화하여 적극적인 신재생에너지 확대와 소비자 선택권을 보장하는 조치가 필요하다. 기업측면에서는 적극적인 수요관리와 신재생을 포함하는 분산전원의 확대가 시급한 과제이다. 소비자측면에서는 탄소고착 완화를 위한 다양한 요금제 도입과 소비자의 의식전환 노력 등이 필요하다. 마지막으로, 정부에서는 수급계획 수립 시 중요하게 고려되지 못했던 다양한 외부 비용들, 예를 들어 환경비용, 사회적 갈등비용 등을 포함하는 제도 개선이 시급히 필요하다.

  • T Recently, the government has been promoting the expansion and supply of renewable energy as an alternative for achieving carbon neutrality and the nationally determined contributions by 2030. In 2020, the Ministries of Industry and Environment and the Korea Forest Service collaborated to build a nationwide onshore wind energy siting atlas considering wind resources and forestry and environmental regulations focused on central regulations. In this study, the ordinances of the local governments were analyzed to examine the effects of regional location regulations on the expansion of onshore wind power energy generation facilities, in addition to those of central regulations. A development permit standard survey of 226 urban plan ordinances of the local governments nationwide showed that presently in 2022, 52 municipalities are applying regulations on wind energy generation facilities by ordinances. This is twice more than that in 2018, when renewable energy power generation facility development was difficult. Additionally, the location regulations applied by these ordinances were organized by items and regions, and regulatory characteristics, such as the number and scope, were analyzed by regions. To analyze the spatial distribution characteristics, JeollaNamdo was selected as the case area. A spatial DB was established for regulated areas based on the regional and central regulations, and the spatial distribution characteristics and the regulatory scope were compared and analyzed.

  • An energy problem has become one of the many Problems awaiting solution to human society. Energy needs to support not only industry, but also building in city. The types of residential building, office building and public building account for much proportion among the totally amount used energy. A public institution shows a fine example for an energy conservation in the present situation. But, the amount used energy of electricity, air-conditioning and heating is different from a building use and condition. Because the building data of the energy consumption by a load is insufficient, it is unable to select a proper energy source. According to this study, it analyzed an energy load by each building that had investigated the actual conditions of energy consumption about public buildings in Daegu City. In order to plan the efficient energy use both existing buildings and new buildings, this study will present the efficient energy use plan, which has operated to new buildings of a public institution, at present.

  • As the electric power industry has been revolutionarily transformed such that the distributed energy resources have been interconnected with power systems and a variety of energy service providers have been appeared, the need of Consumer Energy Portal as a core of two-way communication and service infrastructure between power suppliers and consumers has been gradually increased. Consumer Energy Portal can be thought of as a combination of hardware and software enabling two-way communication between energy service providers and equipment within the consumers' premises or a physical and logical link between consumers' in-building networks and wide-area access networks. In other words, Consumer Energy Portal can make the way the power industry has been traditionally operated the web-based way, enabling two-way interactions between energy service providers and consumers and mutual networking between end users' equipment. Thus, Consumer Energy Portal can be a kind of Service portal that provides new value-added services and efficient power operations that in the past. In this paper, for ESPs' integrated resources management, demand side management and value-added service provision, we have established the two-way access network that can gather real-time metering data using ZigBee technology and control physically networked equipment.

  • This paper recognized a need in the architecture, engineering, and construction industry for new programs and methods of producing reliable energy simulations using BIM (Building Information Modeling) technology. Current methods and programs for running energy simulations are not very timely, difficult to understand, and lack high interoperability between the BIM software and energy simulation software. It is necessary to improve on these drawbacks as design decision are often made without the aid of energy modeling leading to the design and construction of non-optimized buildings with respect to energy efficiency. The goal of this research project is to develop a new methodology to produce energy estimates from a BIM model in a more timely fashion and to improve interoperability between the simulation engine and BIM software. In the proposed methodology, the extracted information from a BIM model is compiled into an INP file and run in a popular energy simulation program, DOE-2, on an hourly basis for a desired time period. Case study showed that the application of this methodology could be used to expediently provide energy simulations while at the same time reproducing the BIM in a more readably three dimensional modeling program. With the aid of an easy to run and easily understood energy simulation methodology, designers will be able to make more energy conscious decisions during the design phase and as changes in design requirements arise.

  • This experiment was conducted to determine the effect of variety and planting year on the nutritive values of corn fed to growing pigs. Four corn varieties examined in this experiment were planted in the same village located in Longhua County, Heibei Province, China, in 2012, 2013, and 2014, respectively. During each year, corn was hand-harvested in early October and sun dried to about 14% moisture content. Three batches of twenty-four barrows ($33.27{\pm}4.30$, $31.88{\pm}2.93$, $34.21{\pm}3.81kg$ body wight [BW] in 2012, 2013, and 2014, respectively) were used and allotted to a complete block design with 4 diets and 6 replicate pigs per diet. Pigs were individually placed in metabolic crates. The four experimental diets were formulated by mixing each variety of corn and vitamins and minerals, respectively. A five-day collection period followed a seven-day diet acclimation period. The results indicated that variety of corn significantly influenced the available energy content (digestible energy [DE] on dry matter basis, p<0.05; metabolizable energy (ME) on dry matter basis, p<0.05, respectively), and the apparent total tract digestibility (ATTD) of organic matter (p<0.01), dry matter (p<0.05), gross energy (p<0.05), neutral detergent fiber (p<0.01), acid detergent fiber and ether extract (p<0.05). The planting year also significantly influenced the available energy contents (DE on dry matter basis, p<0.05; ME on dry matter basis, p<0.01, respectively) and the ATTD of neutral detergent fiber (p<0.01), acid detergent fiber (p<0.01), crude protein (p<0.01), and ether extract (p<0.01). No interaction was observed between the variety and planting year in DE and ME contents in corn. In conclusion, the variety and planting year significantly influenced the available energy and nutrient digestibility of corn fed to growing pigs.
