摘要
介绍了外墙外保温技术的发展概况,外墙外保温系统典型的施工步骤及保温性能。分析了在两部制热价下外墙外保温技术对可变热费的影响,研究了采用某外墙外保温系统进行既有建筑节能改造,当热价为40元/GJ时,不同分摊率下的外墙外保温系统的投资回收期。
The development general situation of external thermal insulation technology for external wall, its typical construction procedure and the thermal insulation performance are introduced. The influence of external thermal insulation technology for external wall on variable charge for heating under two heat prices is analyzed, the study is made on the investment recovery period of external thermal insulation system for external wall at different shared ratios when the energy saving renovation of existing buildings is conducted for a certain external thermal insulation system with heating price of 40 yuan/GJ.
