基于实际项目的绿色建筑全寿命周期碳排放水平分析
Analysis of carbon emission levels throughout life cycle of green buildings based on actual projects
摘要:
建筑碳排放计算已成为硬性要求,绿色建筑作为建筑行业重要部分及关键碳减排路径之一,对其碳排放情况进行分析具有重要意义。本文以获得绿色建筑标识的59个公共建筑和26个居住建筑实际项目为研究对象,采用全寿命周期碳排放分析方法,归纳、统计不同阶段、不同星级、不同功能绿色建筑的碳排放水平,并根据绿色建筑全寿命周期碳排放特征,提出了绿色建筑设计、建造与运维管理减碳措施建议,以期推动规模化推广绿色建筑、实现全过程协同降碳。
Abstract:
The assessment of carbon emissions in the construction sector has evolved into a compulsory endeavor.Within this domain,green buildings play a pivotal role as a principal avenue for carbon mitigation,making the analysis of their carbon footprint critically important.This study focuses on 59 public buildings and 26 residential buildings that have obtained green building certifications.Employing a comprehensive life cycle carbon emission evaluation approach,it delineates and quantifies the carbon emission profiles of green buildings across various stages,star ratings,and functionalities.Based on the carbon emission characteristics of the life cycle of green buildings,the paper advocates for targeted carbon reduction strategies in the design,construction,and operational management phases of green building projects.Such measures are aimed at facilitating the widespread adoption of green buildings and fostering a collaborative approach towards comprehensive carbon minimization.
