摘　　要：目的研究办公建筑在保温层厚度不同时的能耗情况,提出最佳保温层厚度及最小费用的确定方法.方法以沈阳地区某高校办公楼为研究对象,利用De ST能耗模拟软件对建筑不同保温层厚度时的能耗进行模拟计算,并运用全生命周期耗费分析方法建立保温层的数学模型,计算得出最佳保温层厚度和最小费用,最后利用编程软件形成实用型的节能改造工具.结果该建筑在利用水源热泵采暖时最佳保温层厚度为45 mm,保温层最小费用为143.84元/m2.结论沈阳地区办公楼建筑总负荷随着保温层厚度的增加而减小,最佳保温层厚度及保温层最小总费用均和保温层生命周期年限、采暖度日数、基层墙体热阻、燃料种类等密切关系.This paper studied office building energy consumption with different insulation thicknes- ses and determined the optimum insulation thickness and the minimum cost. Taking an office building in Shenyang as a research target, based on the life-cycle cost analysis, a mathematical model for insulation layer was built. Using the DeST energy consumption simulation software, of- fice building energy consumption indexes with different insulation thickness were simulated. The favorable thickness and the minimum cost were determined. Results show that by heating with wa- ter-source heat pump, the optimum insulation thickness of the office building is 45mm and the the minimum cost of insulation layer is 143.84 yuan per square. Conclusion is that energy consump- tion of office buildings in Shenyang decreases with the increase of insulation thickness. The opti- mum thickness and minimum cost are closely related to lifecycle years, heating degree days, ther- mal resistances of the base course wall and fuel types.
