摘　　要：建筑业是能源消耗与碳排放重点领域,绿色建筑技术可以有效降低该领域的碳排放。本文以位于寒冷地区的某高校学生公寓为研究对象,首先根据相关国家标准核算了该建筑全生命周期的碳排放量。然后利用情景分析法,对学生公寓建筑减碳潜力进行了深入分析,计算该建筑物化阶段及运营阶段的碳排放敏感性系数,最后提出了合理的学生公寓建筑减碳技术策略。结果显示,在建筑50 a的全生命周期内,总碳排放为3638.57 kgCO_(2)·m^(-2)。其中,建筑运营阶段的碳排放量占全生命周期碳排放为81.49%,物化阶段为16.84%,拆除阶段为1.67%。具体情景模拟及计算结果为:情景1依据绿色建筑三星标准增加了绿化面积,减碳率为9.47%;情景2通过降低围护结构的传热系数,减碳率为12.90%;情景3针对生活热水系统,使热泵COP提高10%,减碳率为21.57%;情景4对照明节能系统进行了优化,减碳率为18.14%;情景5为情景1、2、3、4共同作用下的绿色技术情景,碳减排效果显著,减碳率为28.23%。本文研究结论可为公寓建筑减碳措施的研究提供一定的参考依据。The construction industry is a key sector for energy consumption and carbon emissions,and green building technology can effectively reduce carbon emissions in this sector.This paper takes a university students’apartment located in a cold region as the research object.Firstly,the carbon emissions over the full life cycle of the building are calculated according to relevant national standards.Then,by means of the scenario analysis,an in-depth analysis of the carbon reduction potential of the students’apartment buildings is conducted,and the carbon emission sensitivity coefficients for both the embodied and operational stages of the building are calculated.Finally,reasonable technical strategies for carbon reduction in students’apartment buildings are proposed.The results show that over the 50-year full life cycle of the building,the total carbon emissions amount to 3638.57 kgCO_(2)·m^(-2).Among them,carbon emissions during the operational stage account for 81.49%of the total life cycle emissions,the embodied stage accounts for 16.84%,and the demolition stage accounts for 1.67%.The specific scenario simulations and calculation results are as follows:Scenario 1 increases the green area based on the three-star green building standard,achieving a carbon reduction rate of 9.47%;Scenario 2 reduces the heat transfer coefficient of the envelope structure,achieving a carbon reduction rate of 12.90%;Scenario 3 targets the domestic hot water system by increasing the heat pump’s coefficient of performance(COP)by 10%,achieving a carbon reduction rate of 21.57%;Scenario 4 optimizes the lighting energy-saving system,achieving a carbon reduction rate of 18.14%;and Scenario 5 combines Scenarios 1,2,3,and 4 into a green technology scenario,resulting in significant carbon reduction effects with a carbon reduction rate of 28.23%.The findings of this paper can provide a certain reference for research on carbon reduction measures for apartment buildings.
