项目摘要

Having explored potential resource values of abandoned gap-spaces between buildings, this research was aimed at developing technologies to enhance efficient use of spaces, improve earthquake-proof and energy-saving performances and facilitate renewal of building services of existing building stocks.With regard to improving earthquake-proof performance of small building built in 1960's, the major problem apart from their poor structural strength is the fact that structural connection of adjacent buildings of more or less the same size would not result in effective absorption of seismic energy. Our solution is to add a small mass over the rigid isolator frame built on top of the buildings, and with this retrofitting technology it was proved that torsion, deflection and response of the existing structures can be greatly reducedThe basic idea to minimize energy consumption for heating and cooling is to reduce thermal load by enveloping a group of adjacent small buildings, i.e. closing gap-spaces between building and adding second skins to existing facades and roofs. The result of thermal response analyses have shown that more than 50% of energy for heating during Winter can be saved by simply closing gap-spaces between buildings and that further energy saving can be achieved by combining it with double skin facades and additional roof skins.In order to facilitate renewal work of building services, a multi-storey service rack unit has been developed and tested. The steel unit, assembled in the gap-space between buildings and suspended from the roof top without damaging existing structure and finishing, holds racks each of which can carry maximum 500kg of piping, ducting, cooling units, boilers, etc. The three storey high test assembly was completed within one day.

通过挖掘废弃建筑间隙的潜在资源价值，旨在开发技术以提高空间的高效利用，提高抗震节能性能，促进现有建筑结构的更新。对于60年代S建造的小建筑，提高抗震性能，除了结构强度较差外，主要问题是大小大致相同的相邻建筑的结构连接不能有效吸收地震能量。我们的解决方案是在建筑顶部的刚性隔震框架上增加一个小质量，通过这种改造技术，可以大大降低现有结构的扭转、挠度和响应。最小化供暖和制冷能耗的基本思想是通过包围一组相邻的小建筑来降低热负荷，即关闭建筑之间的间隙，在现有的立面和屋顶上增加第二层蒙皮。热响应分析的结果表明，冬季采暖的能耗可以通过简单地关闭建筑之间的间隙来节省50%以上，而将其与双层幕墙和增加屋顶蒙皮相结合可以进一步节能。为了方便建筑服务的更新工作，已经开发并测试了一种多层服务机架单元。钢结构单元安装在建筑物之间的缝隙中，悬挂在屋顶上，不破坏现有结构和装饰，容纳机架，每个机架最多可承载500公斤管道、管道、冷却装置、锅炉等。三层高的测试组件在一天内完成。
