序言:在全球能源供应越来越紧张的今天,建筑能耗却一直居高不下,其在总能耗所占的比例也越来越重。而“被动建筑”作为生态节能领域的一项新技术,其技术性能、经济性以及它在欧洲的大量实践证明,是我们建设节约型社会一个很好的选择。 Preamble: In today's increasingly tense global energy supply, building energy consumption has remained high, the proportion of its total energy consumption is also more and more important. As a new technology in the field of ecological energy saving, “passive construction” has proved its technical performance, economy and its extensive practice in Europe. It is a good choice for us to build a conservation-oriented society.
