Abstract：The thermal insulation technology for exterior walls is one important way to improve building thermal performance in severely cold regions by significantly reducing building energy consumption and reduce operating costs. As the insulating layer thickness increases, the energy efficiency rate improves, but the problem of reconstruction cost also must be considered. Determination of the optimal insulating layer thickness should simultaneously consider energy savings and the economy of exterior wall reconstruction. This paper takes a multi-story office building in Yichun city as an example of a severely cold region building and analyzes the annual energy consumption of three different materials' external thermal insulation systems, applying the whole life cycle method to simultaneously determine the most economic thickness of the insulating layer of the different thermal insulation systems. The findings provide methods and data references for designers.
