Creation of Homeostatic Network System of Regional Public Facilities by Utilizing the Stock of Public Buildings and Houses

本研究的目的是通过灵活转换和多用途利用现有和新的公共建筑，并利用现有的区域公共住房存量，开发延长现有公共建筑使用寿命和构建区域公共设施网络的方法。研究结果如下：首先，选取东京都多摩市为研究目标区域，收集研究的基本资料。对学校、市政机关等所有市政建筑进行调查，并将其建造年份、规模、结构、改建、维修历史等数据存入数据库。将目标区域内各行政区域的人口变化数据存入数据库，并对未来各行政区域的人口进行预测。利用该数据库，开发了一种利用现有公共建筑重新安排社区设施规划的方法。该方法包括三个步骤。首先，根据社区设施的名称、设备和用途，将各类游客空间划分为几种类型，并对这些类型空间的游客现状进行调查。其次，估算居民对社区设施空间类型的需求。第三，考虑到现有公共建筑的容量，将满足估计需求所需的空间分配给现有公共建筑。还开发了一种量化市政建筑改造潜力的方法。该方法包括两个步骤。首先，根据尺度标准对市政建筑的房间进行了分类，分析了各类房间的施工方法。其次，根据规模标准和建设方法确定了转化潜力。

The purpose of this study is to develop methods to lengthen the lifetime of existing public buildings and to build a network of regional public facilities, by utilizing the existing and new public buildings through flexible conversion and multipurpose use and by utilizing the existing regional public housing stock. The result of the study is as follows.First, the study selected Tama City in Tokyo Prefecture as the target area and basic information for the study was collected. All municipal buildings such as schools and municipal offices were surveyed, and their data in terms of year of building, scale, structure and history of conversion, repair were stored in a database. The data of population change of all administrative districts of the target area was also stored in a database and the future population of each administrative district was forecasted.Using the database, a method for the rearrangement planning of community facilities by utilizing exiting public buildings was developed. The method consists of three steps. First, various spaces for visitors to the community facilities are classified into several types according to their names, equipment and usage, and the current situation of visitors to those types of spaces is surveyed. Second, the demand of the residents on the types of spaces in the community facilities is estimated. Third, the spaces necessary to meet the estimated demand are allocated to the exiting public buildings in consideration of their capacity.A method to quantify the potential of conversion for municipal buildings was also developed. The method consists of two steps. First, the rooms of the municipal buildings were classified in terms of the scale criteria, and construction methods of each type of rooms were analyzed. Second, the potentiality for conversion was determined by the scale criteria and construction method.
