基于LCA的装配式建筑全生命周期碳排放研究——以重庆市某轻钢装配式集成别墅为例

Research on Carbon Emissions of Assembly Building Life Cycle based on LCA:Take a Light Steel Assembly Integrated Villa in Chongqing as an Example

基于装配式建筑建造、使用、废弃3个阶段资源能源消耗的基础数据,构建装配式建筑生命周期评价模型,并利用该模型系统核算重庆市某轻钢装配式集成别墅全生命周期的总碳排放量,识别各个阶段碳排放的影响因素并对碳排放贡献率和灵敏度进行评价,从而提出改进建议,研究结果可为建筑领域的节能减排提供基础数据,并促进装配式建筑的可持续发展。

This paper builds a life cycle evaluation model based on the data of the three stages of energy consumption in the construction,use and disposal of assembly building. Then,uses the model to calculate the total carbon emissions of a light steel assembly integrated villa in Chongqing city,identifies the influencing factors of carbon emissions at all stages,and evaluates the contribution rate and sensitivity of carbon emissions,and thus puts forward the improvement suggestions. The results can provide basic data for energy saving and emission reduction in the construction field,and promote the sustainable development of assembly buildings.
