鲁中地区农村住宅碳排放分析

Analysis of rural residential carbon emissions in central Shandong

农村建筑碳排放总量控制是提升农村居住环境质量的关键措施。文章以鲁中地区典型农宅为研究对象,围绕其功能、空间、材料、结构、建造方式,分析住宅设计与建造中存在的问题,计算其全生命周期各阶段的CO_(2)排放量,探索不同建筑材料、能源结构及生活习惯的农宅碳排放特征,阐明其碳排放规律。结果表明:鲁中地区典型农宅使用阶段的CO_(2)排放量占全生命周期的70%~80%;物化阶段的CO_(2)排放量占全生命周期的20%~30%;减少农村住宅碳排放的关键是选择低碳建筑构件和材料,合理布置农宅平面布局,调整现有能源结构,使用太阳能等清洁能源;设置庭院绿化,增加农宅建筑碳汇。

Total carbon emission control of rural buildings is a key measure to improve the quality of rural residential environment.The article takes typical rural residences in central Shandong as the research object,analyses problems existing in the design and construction of rural residence in the region around the function,space,material,structure,construction method of rural residences,calculates every phase of the life cycle of the CO_(2) emissions,explores the carbon emissions characteristics of rural residences with different building materials,energy structure and living habits,and clarifies the carbon emission law of rural residences in central Shandong.The results show that the CO_(2) emissions in the use phase account for 70%-80%of that in the life cycle;the CO_(2) emissions in the materialization phase account for 20%-30%.The key to reducing the carbon emissions of rural residences is to choose low-carbon building components and materials and rationally arrange the plane layout,to adjust the existing energy structure,to use solar energy and other clean energy,to set up garden greening,and to increase the carbon sink of rural residences.
