This paper reveals both the operational situation and the cause of the error occurred in wind turbine generator system of Hangwon wind farm in Jeju island. The four wind turbines were selected for this work, and the monitored period was for six months. Wind resource in the wind farm was analyzed, and the estimated energy production was compared with the actual energy production. As a result, with a decrease of system error, the estimated energy production was in good agreement with the actual energy production. The errors occurring in components such as gearbox and hydraulic motor affected the Availability of the wind turbine. Also, poor external conditions such as a strong wind, lightning and gust caused a standstill of wind turbines.

The awareness of ecological friendliness has been emerging in the recent years, and the application to housing is quite notable. The purpose of this study is to evaluate environment-friendly planning factor in Environment-friendly Housing Certification. For this purpose, this study has analyzed 5 multi-family housing in Environment-friendly Housing Certification. The findings of this study are as follows: The application of environment-friendly planning factor in interior space are limited. Most of plans are located in south. The variability of floor plan is not applied but the built-in storage is well-applied. Environment-friendly finishing material and the garden-style balconies was applied in a passive way. This analysis showed current status of planning factor of unit apartment in Environment-friendly Housing Certification and proved basic information for future direction.

국토해양부(장관 정종환)는 최근 연세대 친환경건축연구센터와 서울시 강동구가 협의('09.8)를 통해 친환경 공동주택 가이드라인을 마련함에 따라 강동구부터 '저에너지 친환경 공동주택 가이드라인' 시행에 들어 간다고 밝혔다. 가이드라인의 주요내용은 공동주택 재건축시 냉 난방 에너지 총 소비량의 40% 이상을 절감하고, 관리동 등 공용시설의 제로에너지화, 지역특성에 맞게 생태면적률 40%이상 확보, 단지내 인공생물 서식공간 조성의 의무화 등이다. 강동구는 앞으로 지어지는 재건축정비사업의 공동주택 모두에 가이드라인 내용을 반영하여 친환경 공동 주택으로 건설을 추진할 계획이며, 특히 고덕지구($1,239,407m^2$, 18,540가구) 및 둔촌지구($626,235m^2$, 9,090가구)부터 적용하여 친환경공동주택단지를 조성할 전망이다.

본 연구는 '01년 이후 민간 제휴업체에 의해 추진되고 있는 주택공사 사이버아파트 운영체제의 문제점을 분석하고, 향후 기술발전 추세와 정부방향을 검토하여, 바람직한 운영체제를 제시하였다. 아파트 단지 홈페이지 위주의 사이버아파트는 향후 홈네트워크 기반의 디지털홈으로 발전될 것으로 예상되며, 정부도 지능형 홈네트워크를 차세대 10대 성장동력산업으로 선정하는 등 육성의지를 표방하고 있다. 현재 사이버아파트 운영은 입주자 특성에 부합하는 정보제공 불가능, 관리정보의 온라인 제공 곤란 등 운영상 문제점이 나타나고 있으며, 이는 아파트 단지 홈페이지가 활성화되지 못하는 원인으로 작용하고 있다. 이에 따라 사이버아파트 구축현황을 분석하고 효율적인 운영 체제를 제시하였다.

최근 에너지 효율의 중요성이 높아지고 에너지 공급 형태가 다변화하면서 다양한 에너지원을 효율적으로 관리할 수 있는 마이크로그리드 개념이 중요해지고 있다. 본 연구의 산업단지 마이크로그리드 열거래 플랫폼은 실증사이트의 전기 및 열에너지 모니터링 기능과 열에너지 거래 정산 기능을 가지며, 이를 위해 정확하고 안정적인 실증사이트 데이터가 필요하다. 하지만 실증사이트 데이터는 에너지 단위의 불일치, 센서 및 현장 운영상태에 따른 불안정성 등의 문제가 있어 수집 직후 열거래 플랫폼에서 활용할 수 없다. 따라서 수집된 데이터를 활용하기 위해 엔진 최대 출력량, 최대 전력 사용량 등의 변수별 특성을 고려하여 데이터 전처리 프로세스를 설계 및 적용하였다.

The background of this study is to examine the structure of housing price of which characteristics are not equal but hierarchical in the apartment complexes. So, the purpose of this study is to analyze the influences of apartment complex characteristics on the housing price within the same regional boundary by HLM. The data used as dependent variables were the market prices of 938 units from 29 apartment complexes by stratified sampling. The 2nd level independent variables is the Housing complex characteristics which are composed of the housing complex & locational variables and the 1st level independent variables are the unit characteristics. The results are as follows. First, the first model shows that the 2nd level variables explains 68% of the housing prices. Second, the influential variables of the 1st level unit variable are 'dwelling exclusive area', 'floor of dwelling' and 'direction of dwelling'. Third, the influential variables of the housing complex variables in the 2nd level are 'lot area', 'the building-to-land ratio', 'the number of unit', 'the number of parking lots per unit', 'Green space area' and 'open space area per unit'. The last, the influential variables of the housing locational variables in the 2nd level are 'distance to subway and park' and the number of school and park within a radius of 1km.

This study aims to research the characteristics of space composition and location for the rural community center. The phenomenon of urban areas from rural areas by the dismantlement of the community is being increasingly deepened. The current village welfare center in the rural villages of the dismantlement phenomenon of the community in rural areas can not be solved alone. The location of the Community Center in rural villages for the interaction of existing local inhabitants and should be located where possible near existing villages. This thesis studies and analyzes the characteristics of rural villages in the rural new town project districts. The basic function of the community center space analysis model is the Public service space, the Communication space, the Health space, the Amenity space, the Education space(including the childcare). This study analyze the local characterristics, the location type and the floor plan characteristics about the Community Center in rural villages by the rural new town example project.

This study emphasizes a new senior housing type which can provide individual housing units and common facilities for retirees, particularly who will be retired from universities. It is called a university-based retirement community. This study conducted a questionnaire survey to investigate future residents' needs for architectural environments that included housing types, common facility features, and proximity, and also development methods in response to the university involvement levels. The survey questionnaire was administered in one national university in Korea. A total of 214 responses were valid for statistical analyses. Major findings are as follows: Over 65% of the respondents were willing to live in the university-based retirement community. Regarding the location of the community, they responded the community would not need to be located on campus. Preferred common facilities in the UBRC were indoor fitness centers, the shuttle bus stops connecting to the adjacent areas, and bath and sauna facilities. The respondents emphasized university's contribution toward offering educational programs for UBRC residents. Lastly, their responses to the university role and involvement in the development and construction process were identified. This study results are expected to provide essential information for facilitating the Korean model of university-based retirement communities in the future.

The purpose of this study was to identify some residential characteristics of Post-retirement and characteristics of the Continuing Care Retirement Communities (CCRCs) favored by those baby-boomer generations soon retiring. A web-based online survey was conducted with middle-class baby-boomers living in the Seoul-Incheon-Gyengki capital area and the five metropolitan cities of Korea between 9th and 20th of February in 2017. A total 0f 507 responses were valid for statistical analysis. The findings obtained that they preferred living Urban outskirts after retirement; Desired area of post-retirement was differentiated depending on asset and educational attainment; 63.4% of respondents had no intentions to live with adult child; a combination of independent living and assisted living was the most preferred form of the CCRCs; Over 80% of respondents had intention to live in independent living, assisted living and nursing home; and Intention to live in assisted living and nursing home was differentiated depending on Intention to live with adult child. Among the four Community-linked types, the Hospital-based one was most popular. The University-based and Religion-based ones were then preferred by females than males. The results obtained here can be used for reflecting the residents needs when planning the CCRCs in Korea.
