目前,我国既有建筑存量400亿 m~2,每年将新建20亿 m~2的建筑.建筑物用电4600亿kwh。我国住宅建筑使用的能耗约占全国总能耗的27.5%。如果延续目前的耗能状况,预计到2020年底,其将约占全社会总耗能的46 7%。据国际著名咨询公司 MCkensey 统计,我国公共智能建筑的单位能耗为1 40～1 60元/年·平方米。笔者也曾经做过调查,结论如下:1.商住办公楼每万平方米的耗电费用大约在100～200万元左右。2会展建筑、机场候机楼每万平方米电费在300～400万元左右。多种信息显示,我国的能源形势严峻。在笔者参加的
At present, the existing stock of buildings in our country is 40 billion m 2, and 2 billion m 2 new buildings will be built each year, and the building will consume 4,600 billion kwh of electricity. The energy consumption of residential buildings in China accounts for about 27.5% of the total energy consumption in China. If the current energy consumption continues, it is estimated that by the end of 2020, it will account for 46.7% of the total energy consumption of the whole society. According to the statistics of the internationally renowned consulting firm MCkensey, the energy consumption of public intelligent buildings in our country is 140 ~ 160 yuan / a · m 2. The author has also done a survey, the conclusions are as follows: 1. Commercial and residential office building every million square meters of electricity costs about 100 to 2 million yuan. 2 Convention and Exhibition Architecture, airport terminal every million square meters of electricity in the 300 ~ 4 million yuan. A variety of information shows that China’s energy situation is grim. At the author’s participation
