基于居民生活的老旧小区碳排放评估及低碳更新策略研究——以苏州姑苏区典型住区为例

Carbon Emission Assessment and Low-Carbon Renewal Strategy Research Based on Residents’Daily Life:a Case Study of Typical Residential Areas in Gusu District,Suzhou

住区作为城市的基本空间单元,进行低碳更新是实现“低碳城市”的重要抓手。老旧小区的能源消耗量大和资源利用率低,是住区低碳更新中亟待解决的难题。本文以苏州市姑苏区12个典型老旧小区为例,从居民生活方式切入,进行住区碳排放测算和碳排放效率测度,评估其碳排放和碳效率水平。在此基础上,结合小区既有改造类型,基于“改造类型—碳排放量—碳排放效率”三维度构建了决策框架,制定低碳更新路径,在建筑能源、交通出行、资源配置、废弃物处理和生态环境五个方面提出差异化的低碳更新策略,以期为其他地区小区低碳更新工作的开展提供指导。

The residential area,as the basic spatial unit of the city,plays a crucial role in achieving a‘low-carbon city’through low-carbon renewal.The high energy consumption and low resource utilization in old residential communities pose significant challenges that urgently need to be ad-dressed in the process of low-carbon renewal.This study takes 12 typical old residential neighborhoods in Gusu Dis-trict,Suzhou,as examples.It investigates residential car-bon emissions and carbon efficiency based on residents’lifestyles,assessing their levels of carbon emissions and carbon efficiency.On this basis,combined with the existing types of community renovation,a decision-making frame-work was constructed based on the three dimensions of‘renovation type—carbon emissions—carbon emission ef-ficiency’.A low-carbon renewal path was formulated,and differentiated low-carbon renewal strategies were proposed in five aspects:building energy,transportation,resource al-location,waste disposal,and ecological environment.The aim is to provide guidance for the implementation of low-carbon renewal work in other community areas.
