项目摘要

The end of the mass production and consumption era suggests the significance of conservation efforts of the global environment, including the saving of resources and energy as well as circulation and reuses of resources, of which measures are under discussion and on the course of realization in different fields. Architectural industry, which is no exception to those efforts, is also addressing means for environmental conservation. For this purpose, statistic data are required as the basic materials to estimate the discarding of existing buildings. At present, such data are insufficient, and they must be promptly enhanced. This study, therefore, discusses the situation of housing stock and its loss as well as the estimated destruction based on the quantity described in municipal "Fixed Assets and Houses Ledger, " considered to be the most reliable data on the stock and eliminated units of residential buildings. It gave the findings below. The study was conducted on the data in 1990.1. T … More he situation of stock and loss of exclusively residential, apartments and multiple-purpose wooden houses and farm houses has been clarified. The general loss rate of wooden houses is about 1.45%, resulting in annual elimination of about 460,000 units. The distribution of house stock by building years has revealed its peak at 14 to 20 use years, while the distribution of house elimination has its peak at 20 to 23 use years.2. For non-wooden residential houses, the situation of stock and loss of reinforced concrete, steel-frame, and light gauge steel-frame buildings was clarified. The general loss rate is broadly 0.60%, resulting in annual elimination of about 22,000 units. The stock distribution by building years contains chiefly buildings of 18 years or less in age, and the distribution of building elimination has its peak at 16 to 20 use years.3. The quantity of construction waste from abolished residential houses can be estimated based on the distribution of stock and the number of eliminated units by building years. In addition, the stock of residential buildings in the country consists of buildings of 20 years or less in age, which can contain harmful substances such as chemicals in new building materials, and agricultural chemicals used in preservative agents, whose exhaust can endanger the environment. These problems should be further studied in the quality phase. Less

大众生产和消费时代的结束表明，全球环境的保护工作的重要性，包括节省资源和能源以及资源的流通和资源，其中正在讨论这些措施以及在不同领域的实现过程中。建筑行业也不例外，这也是解决环境保护的手段。为此，需要统计数据作为估计丢弃现有建筑物的基本材料。目前，此类数据不足，必须迅速增强。因此，这项研究讨论了住房库存及其损失的状况以及基于市政“固定资产和房屋分类帐”中描述的数量的估计破坏，这是该股票上最可靠的数据，并消除了住宅建筑的单位。它给出了下面的发现。这项研究是在1990年1月对数据进行的。…更多的股票状况以及唯一的居民，公寓和多功能木屋和农舍的损失已被阐明。木制房屋的一般损失率约为1.45％，导致大约460,000个单位消除。建筑年的房屋库存分配揭示了其14至20年使用年的高峰，而房屋消除的分布在20至23岁时的峰值。2。对于非木制居民的房屋，阐明了库存和钢筋混凝土，钢制和轻型钢框架建筑物的损失。一般损失率通常为0.60％，导致大约22,000个单位的演变。建筑年的股票分配主要包含18岁以下的建筑物，建筑物的分布在16至20岁时达到了高峰。3。可以根据库存的分配和建筑年的淘汰单位数量来估算废除居民房屋的建筑废物数量。此外，该国居民建筑物的库存包括20岁以下的建筑物，其中可能包含有害物质，例如新建筑材料中的化学物质，以及在防腐剂中使用的农业化学物质，其排气器可能危及环境。这些问题应在质量阶段进一步研究。较少的
