摘要随着“双碳”战略深入推进,既有建筑节能改造成为城市碳减排关键领域。本文以南阳市为研究对象,构建“结构—环境—智能”三元协同减碳体系,提出围护结构改造、室内环境优化与智能调控的集成路径。研究表明:外墙保温层厚度优化使空调能耗降低18.7%,温湿度独立控制系统降低潜热处理能耗42%,物联网+BIM平台提升运维效率70%。通过全生命周期评估模型验证,改造项目碳排放强度下降32.8%,单位减碳成本318元/tCO_(2),投资回收期缩短至7.8年。研究构建的政策—市场—技术协同机制,为中部地区城市建筑低碳转型提供了可复制的解决方案。 With the deepening of the"dual carbon"strategy,energy-saving renovation of existing buildings has become a key area for urban carbon reduction.This article takes Nanyang City as the research object,constructs a"structure environment intelligence"ternary collaborative carbon reduction system,and proposes an integrated path of enclosure structure renovation,indoor environment optimization,and intelligent regulation.Research has shown that optimizing the thickness of the external wall insulation layer reduces air conditioning energy consumption by 18.7%,the independent temperature and humidity control system reduces latent heat treatment energy consumption by 42%,and the IoT+BIM platform improves operation and maintenance efficiency by 70%.Through the verification of the full lifecycle assessment model,the carbon emission intensity of the renovation project has decreased by 32.8%,the unit carbon reduction cost is 318 yuan/tCO_(2),and the investment payback period has been shortened to 7.8 years.The policy market technology synergy mechanism constructed through research provides replicable solutions for the low-carbon transformation of urban buildings in the central region.
