Advanced utilization methods of closed hotels for the long live architecture and the vitalization of rural areas

建筑的长寿是当今社会的任务，而建筑的再利用和改造是实现建筑长寿的有效手段。本研究针对社会寿命较短的饭店，因为其新开量仍然很大，其需求特性受商业环境或社会变化的影响很大。本研究以《日本旅馆年鉴》中的2100家旅馆中近10年内更换名称、更换经营者或关闭的旅馆为研究对象，旨在获得有效利用旧旅馆和使新旅馆长寿的智慧。本研究的方法和步骤如下。首先，通过向这些酒店的业主等邮寄调查表，明确了变更的情况或情况。其次，通过对21家酒店的听证调查，分析了酒店改造的具体内容和影响因素，并提炼出酒店改造中存在的问题和有效利用的智慧，最后，针对现有酒店，提出了酒店改造和再利用的有效利用途径。在新建酒店方面，提出了实现长寿命的原型的重要课题，作为具体方案，展示了城市地区的“向不同经营条件的酒店转变”和城市地区郊区和农村城镇的“向老年住宅或福利设施转变”。在这些计划中，讨论了法律或制度、业务收入和支出模拟等主题，虽然目前有效利用的案例不多，但在有效利用现有酒店和使新建酒店长寿的方法方面获得了许多智慧
