Research Abstract |
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.
