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

这项研究的目的是通过灵活改建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，制定延长现有公共建筑寿命和建立区域公共设施网络的方法。研究结果如下：首先，本研究选取东京都的玉玉市为研究对象，收集了研究的基本资料。对学校和市政办公楼等所有市政建筑进行了调查，并将其建筑年份、规模、结构和改建、维修历史等数据存储在数据库中。将目标区域各行政区的人口变化数据存储在数据库中，并对各行政区的未来人口进行预测，提出了一种利用现有公共建筑进行社区设施改造规划的方法。该方法由三个步骤组成。首先，根据名称、设备和用途将社区设施的各种游人空间划分为几种类型，并调查了这些类型的游人的现状。其次，估算了居民对社区设施空间类型的需求。第三，考虑现有公共建筑物的容量，将满足估计需求所需的空间分配给现有的公共建筑物，并制定了一种量化市政建筑物改建潜力的方法。该方法包括两个步骤。首先，根据尺度标准对市政建筑房间进行了分类，并分析了每种类型房间的施工方法。其次，由规模标准和建设方法决定了转化的潜力。

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.
