Development on Conversion System for Spare Classroom in Public Elementary Schools

如今，在日本的城市地区，由于孩子减少，关闭的学校和闲置的教室的数量正在增加。随着出生率的进一步下降，这些剩余设施的数量预计将会增加，有效地利用这些设施是未来学校设施的一项基本任务。本研究旨在开发公立小学闲置教室转换系统，并验证其有效性。其次，钢结构填充体系的设计不需要对基础建筑进行整体改变，而是可以添加、转移和移除。第三，设计了附加覆层系统和扩建建筑系统，以提高其在建筑用途转换中的性能。此外，我们还制作了填充、覆层和延伸建筑体系相结合的体系。最后，对整个系统进行了转换设计，并对系统的成本、耐久性和总资源进行了价值估算。

In urban areas of Japan these days, the number of closed schools and idle classrooms is increasing due to fewer children. With an anticipated increase in the number of such surplus facilities due to the further declining birth rate, their effective utilization is an essential task for school facilities in the future.This study aimed to develop conversion system for spare classroom in public elementary school and verify its effectiveness.First, we made field surveys to capacity of space in spare classroom of elementary schools and converting area were found out. Second, infill system in steel structure were designed without changing base building wholly, but enable to add, transfer and remove. Third, additional cladding system and extension building system were designed to improve it performance in transferring building use. In addition, we made the infill, cladding and extension building system were combined. Finally, the conversion design of total system were built up, and estimate of value about the cost, durability and total resource were found out.
