The purpose of this study is to analyze the window area ratio distribution of building facade in Tokyo metropolitan area. The survey was carried out in Marunouchi, Kanda, Kasai and Todoriki district. The results of this study were as follows; to propose of window area ratio production method, analyzed and surveyed window area ratio of each district building-used and to compared every wall window area ratio of building. Every wall window area ratio of office district is $20\sim40%$, ones of non-office district is 15% or 35%. Residential area results are every wall window area ratio of apartment is 35%, ones of a house is 15%. To increase of office building to appear that Kanda, Kasai added window area ratio. But, Marunouchi, Todoriki wad not this tendency. Above mentioned results are made out database.

최근 우리나라 도시개발의 양적 확장은 도시의 환경이 제공해주는 공공성에 있어서 우리의 정체성을 잃어버리게 되는 결과를 가져다주었고, 획일화된 공공디자인의 환경적 메시지를 해결해야하는 새로운 과제를 가져다주었다. 도시의 공공환경은 지역의 첫인상을 좌우하는 중심축을 이루며, 그 지역의 전반적인 가치와도 연계되기 때문에 지역의 도시경관 디자인이 잘 형성되어 있느냐, 아니냐에 따라 지역의 가치는 매우 큰 차이를 보이게 된다. 따라서 도시의 스토리텔링을 기초로 도시브랜드화에 따른 지역문화 스토리텔링을 반영한 아이덴티티가 어떻게 활용되고 어떠한 부분에 적용되고 있는 것인가에 대한 객관적인 내용을 검증하기 위하여, 도시 공간 표현의 시각적 물리적 특성을 외부 공간의 특성과 연결시키는 방법의 개념을 잘 적용한 토쿄 마루노우치 거리와 파리 샹젤리제 거리의 도시경관 현황을 분석함으로써 우리의 창의적 도시경관에 대한 디자인 정체성이 무엇인지 재고하고자 하였다.

In Japan, the vacancy rates of office buildings have been at high in big cities since 1992. This problem is especially acute in Tokyo, where it is estimated that over 2.27 million square meters of office floor area will be oversupplied in 2003: big urban redevelopment projects will be completed in 2003. Under these circumstances, International Cooperative Research and Development on Sustainable Urban Management by Conversion of Buildings, called “SUMCOB”, has been carried out. This research aims to regenerate urban areas by converting redundant offices into flats, although instances of conversion are still very few in Japan. This paper introduces part of current results by SUMCOB, and discusses legal problems with conversion and basic capacity of vacant offices in Tokyo. It has been confirmed that there are no constraints concerned with Real Estate Registration Law (although it requires the change of the registration after conversion). and City Planning Law. However, some criteria are incompatible with Building Standard Law and Fire Service Law if the use of the building is changed from offices to flats. Typical incompatibility between offices and flats is lightening. If the buildings do not satisfy criteria for flats, the cost of renovation works for conversion will increase. To examine the basic capacity of vacant office buildings for conversion, field surveys in Tokyo have carried out at three areas: Kodenmacho (Chuo-ku), Toranomon (Minato-ku), and Iwamonocho (Chiyoda-ku). They are typical office areas that are included in center core of Tokyo. In Chuo-ku, the oldest commercial area in Tokyo, textile merchants have been located their headquarters. In Minato-ku, many rental office buildings have been located and several large scale redevelopments are advancing. Chiyoda-ku includes Marunouchi area, which is the prime office area in Japan. Thirty percent of the buildings in survey areas suffer from over twenty percent vacant floor rate, and fifty five percent were constructed before 1990. Especially most of buildings over forty percent vacant floor rate were constructed in 1980s. Vacant office problems haven't been seen in old buildings in Tokyo yet. The number of dwelling units made from office space will influence the conversion scheme. Seventy percent of the office buildings in survey areas have floor area of less than two hundred square meters. If they have been subdivided into two bedrooms type or three bedrooms type, the number of dwelling units in a floor would be less than three. The difficulty of conversion planning derives from frontage size, depth size, and their proportion. The five categories are proposed to grasp actual requirements for converting offices into flats.
