摘要
低辐射地区冬季湿冷,夏季闷热,日较差小,太阳辐射匮乏.本文构建了综合考虑能耗、碳排放和成本的"多目标优化多因素决策"模型,并提出了围护结构热工设计参数的优化方案.夏季,优先采用的措施是减小窗墙比以降低得热;冬季,着重提升外窗保温性能以减少失热.与现行国家标准相比,本研究提供的方案能够将空调能耗降低10.88％,总能耗减少3.17％,成本降低11.03％,碳排放减少8.46％.研究结果为该地区的节能降碳工作提供了理论支撑.
Abstract
In low solar radiation areas,winters are cold and humid,while summers are hot and stuffy,with limited temperature fluctuations and a lack of solar radiation.This study employs a comprehensive"multi-objective optimization and multi-factor decision-making"model,considering energy,carbon emissions and costs.In summer,we prioritize reducing the window-to-wall ratio for heat control,while in winter,we emphasize improving external window insulation to reduce heat loss.Compared to current national standards,our proposal reduces air-conditioning energy consumption by 10.88％,total energy consumption by 3.17％,costs by 11.03％,and carbon emissions by 8.46％.Findings can provide theoretical support for energy saving and carbon reduction in these areas.
