SYSTEMATIZATION OF BUILDING PLANNING, DESIGN, AND RENOVATION FOR EXTENDING FUNCTIONAL DURABLE YEARS

1. 对欧洲、美国和日本的历史环境保护制度进行了比较分析，以澄清日本制度所特有的问题。收集了176个改造、翻新、改造或改造的建筑案例，分析了导致复兴再利用而不是拆除的因素。将影响因素分为六个方面；1)物理因素，2)社会因素，3)经济因素，4)建筑作为文化遗产的价值，5)经济实用价值，6)作为社会或设计资源的实用价值。共发现20种再生再利用技术，可分为三类；1)现有建筑构件或元素的再利用（4种类型），2)室内改造（6种类型），3)新增空间体量（10种类型）。通过对公共设施工作人员的访谈，揭示了日常维护中存在的问题。针对存在的问题，提出了相应的对策。我们有选择地调查了183幢战后建筑（1945年以后建成），这些建筑都有相当详细的维修记录，以系统地整理建筑物维修方面的问题。在有维护意识和老化意识的建筑设计中，重要的是要考虑1)耐久性，2)易于维护，3)经济效益，以及4)灵活性。通过对“奇形怪状”建筑维修人员的问卷调查和对维修公司员工的访谈，揭示了“奇形怪状”建筑维修存在的问题。然后考虑了维护意识设计和面向形式设计的兼容性。以大阪市管理的555个公共设施的维修数据为基础，建立了维修水平预测模型，以便进行合理的管理规划。

1. Institutions for preserving historic environment of European countries, USA and Japan were comparatively analyzed to clarify the problems peculiar to Japanese institutions.2. As many as 176 cases of transformed, renovated, converted, or remodeled buildings were collected to analyze the factors which led to revitalized reuse instead of demolition. The factors are classified into six factors ; 1) physical foctor, 2) social factor, 3) economic factor, 4) value of the building as a cultural heritage, 5) economic utility value, and 6) utility values as social or design resource.3. Twenty types of revitalizing reuse technique were found, which can be categorized into three types ; 1) reuse of existing building parts or elements (four types), 2) interior transformation (six types), and 3) addition of new spatial volume (ten types).4. By interviewing staffs of public facilities, problems in daily maintenance were revealed. Then some measures against the problems were suggested.5. As many as 183 post-war buildings (completed after 1945) with fairly detailed maintenance records were selectively surveyed to systematically sort out the problems in building maintenance. In maintenance-conscious and aging- conscious building design, it is important to consider 1) durability, 2) easy maintenance, 3) economic advantage, and 4) flexibility.6. By making a questionnaire survey to the maintenance staffs of so-called "odd-shaped" buildings, and making interviews to the maintenance company staffs, the maintenance problems in "odd-shaped " buildings were revealed. Then the compatibility of maintenance-conscious design and form-oriented design was considered.7. Based on the maintenance data of 555 public facilities managed by Osaka City, maintenance level prediction model was developed for proper management planning.
