This study aims to suggest the direction of urban planning for coping with climate change focusing on urban metabolism. The study consists of two main parts: literature review and case study. The cases are selected for mixed-use housing estate in Europe, which established the plans for energy saving and efficient use of resources and waste. The case study was carried out in accordance with the framework, which had four aspects that are 'to minimize energy input,' 'to use renewable energy sources,' 'to recycle waste,' and 'to reuse natural resources.' As a result, in all the cases, analysis showed that the circular metabolism system was built for energy, waste and water resources and that the plan satisfying all the aspects of the framework was established. Moreover, main planning elements are different reflecting resource conditions for each case. In conclusion, in order to achieve urban metabolism, it will be necessary to analyze various conditions including the surrounding environment of the region and to introduce planning elements that can maximize the regional potential.

기존의 교류배전 시스템의 신재생 에너지원과의 연동 비용이성을 해결하고 전체 시스템의 효율을 높이기 위해 연구되고 있는 직류배전 시스템으로 전환하기 위해서는 옥내배선용 도선의 재검토가 필수적이다. 따라서 본 논문에서는 직류배전 전압 및 부하전류, 도선의 종류와 길이, 각종 규제사항 등을 고려하여 가정용 직류배전 시스템 적용에 적합한 도선 선정을 위한 가이드라인을 제시하고 이를 보급형 $100m^2$형 주택을 기준으로 한 시뮬레이션을 통해 타당성을 보인다.

Europe and North America are paying attention to residential ESS(Energy Storage System) that can manage energy efficiently. The ESS is a system that stores and manages the electric power by charging and discharging the battery. The ESS is generally used in conjunction with photovoltaic systems. The ESS supplies the load of the power generation time and stores the remaining PV power to supply the load at the non-power generation time. However, due to the high price of residential ESS, low electric rates and increasing block rates, there is no market of residential ESS in Korea. This paper reviews the price condition and the capacity for applying PV and residential ESS to household of apartments using HOMER in Korea.
