这里就日本等国住宅节能八个方面作简要介绍:一、废水资源再循环利用日本在水源缺少时,常常利用建筑物内流出的废水,通过下水道流到沉淀池中,经过沉淀处理后,又回送住宅作为清洗厕所等用水。象新宿国际大厦,日产量4000米~3处理水,供给以新宿三井为主的九座大厦,还设计配水纲,日产8000米~3。每1米~3水需要250日元。二、电脑管理大厦的能源需要量。有一个代表团去日本考察,日本大厦地下室有值班警察通过电脑,从电视和各种仪器观察整幢大厦能源供求的情况,火灾前产生热和烟等安全装置,电梯运行是否正常,路灯亮和熄。电脑控制 Here is a brief description of the eight aspects of energy saving in Japan and other countries: First, recycling of waste water resources When Japan lacks water, it often uses waste water flowing out of the building and flows through the sewers to sedimentation tanks. After sedimentation, it is treated again. Return the house as a toilet and other water. Like the Shinjuku International Building, the daily output is 4,000 meters~3 of treated water. It supplies nine buildings that mainly consist of Shinjuku Mitsui. It also has a design water distribution system, with a daily output of 8,000 meters~3. 250 yen is needed for every 1 meter to 3 water. Second, the computer management building energy requirements. A delegation visited Japan to investigate the presence of police on duty in the basement of the Japanese building through computers, to observe the supply and demand of energy in the entire building from TVs and various instruments, to generate heat and smoke and other safety devices before the fire, whether the elevators were operating normally, and the lights were on.
