碳达峰背景下三江源地区居住建筑节能降碳路径研究

Energy saving and carbon reduction paths of residential buildings in Sanjiangyuan area under carbon peak background

降低建筑领域碳排放对三江源地区居住建筑节能降碳和生态环保具有重要意义。本文分析了建筑运行阶段碳排放的影响因素,运用情景分析法对三江源地区居住建筑运行碳排放进行了中长期预测,提出了该地区居住建筑的碳达峰目标和实现路径。研究结果表明:基础情景下,2030年居住建筑碳排放达到221万t,仍呈增长趋势;达峰情景下,居住建筑碳排放在2030年达到峰值174万t,之后缓慢下降;合理控制建筑规模、实施清洁取暖、新建建筑执行更高节能标准、既有建筑节能改造、电气化与可再生能源应用是三江源地区居住建筑节能降碳的核心措施。

Reducing carbon emissions in the building sector is of great significance for energy saving and carbon reduction of residential buildings and ecological environmental protection in Sanjiangyuan area.This paper analyses the influencing factors of carbon emissions in the building operation stage,uses the scenario analysis method to forecast the carbon emissions of residential building operation in Sanjiangyuan area in the medium and long term,and puts forward the target and path of achieving carbon peak of residential buildings in this area.The study results show that the carbon emissions of residential buildings will reach 2.21 million tons in 2030 under the basic scenario,still showing an increasing trend.Under the peak scenario,the carbon emissions of residential buildings will peak at 1.74 million tons in 2030 and then decline slowly.Reasonable control of building scale,implementation of clean heating,implementation of higher energy efficiency standards for new buildings,energy-saving renovation of existing buildings and promotion of electrification and renewable energy are the core measures for energy saving and carbon reduction of residential buildings in Sanjiangyuan area.
