摘　　要：为研究不同绿色建筑技术在居住建筑运行阶段的减碳潜力,利用CEEB软件,针对不同气候区域的典型居住建筑建立标准模型,通过碳排放模拟得到不同技术对建筑碳排放强度的影响程度。结果表明,不同技术对降低居住建筑碳排放强度的贡献水平受气候区域和建筑类型的影响较小。提升空调能效的减碳潜力最大,采用额定制冷量≤4500 W的1级能效空调的减排率可达到10.51%~12.36%;其次是自然采光被动式技术、太阳能热水技术及光伏发电技术,减排率分别可达到7.77%~12.36%、5.39%~10.03%、5.28%~5.90%;围护结构节能技术对碳减排的贡献较小;与常规节能建筑相比,三星级绿色居住建筑的碳减排优势非常明显,仅在建筑运行阶段就可实现平均碳减排最低达17%,最高达48%。In order to study the carbon reduction potential of different green building technologies in the operation stage of residential buildings,CEEB software was used to establish standard models for typical residential buildings in different climate regions,and the influence degree of different technologies on the carbon emission intensity of buildings was obtained through carbon emission simulation.The results show that the contribution level of different technologies to reducing the carbon emission intensity of residential buildings is less affected by climate regions and building types.Among them,the carbon reduction potential of improving the energy efficiency of air conditioners is the greatest,and the emission reduction rate of level 1 energy efficiency air conditioning with rated cooling capacity≤4500 W can reach 10.51%~12.36%;Followed by natural lighting passive technology,solar hot water technology and photovoltaic power generation technology,the emission reduction rates can reach 7.77%~12.36%,5.39%~10.03%and 5.28%~5.90%respectively;The energy-saving technology of enclosure structure has a relatively small contribution to carbon reduction;Compared with conventional energy-saving buildings,the carbon emission reduction advantages of three-star green residential buildings are very obvious.Only in the building operation stage,the average carbon emission reduction of three-star green residential buildings can reach 17%at the lowest and 48%at the highest.
