运用全寿命周期经济评价理论,建立围护结构全寿命周期经济评价模型,并通过实际工程分析和计算建筑围护结构采用节能材料后的全寿命周期成本,从而得出结论:建筑围护结构运用节能材料不仅降低建筑能耗,同时也降低了建筑全寿命周期成本。 Based on the theory of full life cycle economic evaluation, the economic life cycle assessment model of building envelope is established, and the life cycle cost of building envelope is calculated and analyzed through practical engineering. The conclusion is drawn from the conclusion that the application of building envelope Energy-efficient materials not only reduce building energy consumption, but also reduce the cost of building life cycle.
