The means of attaching thermal insulation layer to the external windows of a building is one of the impor-tant ways to reduce the heating load of the building during the heating season,which has a strong potential for energy saving.Taking a typical single-story industrial plant in a cold region as the research object,the heating load,heat gain and loss of external windows,and natural room temperature change after attaching the external window insula-tion layer are simulated by applying Design Builder energy simulation software,revealing the influence of the insula-tion layer material and the time of attaching the insulation layer on the energy consumption of the building.The ener-gy saving effectiveness of attaching PVC cold-proof film to the external windows at full time is optimal,through which the heating load is reduced by 7.2%,the heat loss through the external windows is reduced by 31.6%,and it has obvious cost-effective.The indoor thermal environment is the most stable at night when attaching EPS thermal in-sulation panels,and its optimal thickness is 40mm,but the economic cost is relatively high.The results of the study may provide data support and theoretical basis for the external window insulation of industrial plants in cold regions.
