摘　　要：我国农村既有居住建筑存量大且能耗普遍较高,具有较大的节能潜力。根据调研情况选取豫东地区农村单层居住建筑功能性房间建立模型,使用Dest模拟软件对建筑节能改造前后的冷热负荷进行模拟计算,根据节能改造前后模型全年累计冷热负荷指标计算节能改造后节能率,考虑资金时间价值选用动态投资回收期作为节能改造项目经济效益评价指标,对节能改造方案的经济性进行分析比较。在此基础上,结合分析及模拟结果提出针对豫东农村地区建筑节能改造建议,为豫东地区农村住宅的规模化节能改造提供理论依据,助力“双碳”目标的实现。The existing residential buildings in rural areas of China have a large stock and generally high energy consumption,offering substantial potential for energy savings.In this study,a functional room of a rural single-storey residential building in eastern Henan Province was selected to establish a model according to the investigation situation.The Dest simulation software was used to simulate the cooling and heating load of the building before and after the energy-saving renovation,and the energy-saving rate after the energy-saving renovation was calculated according to the annual cumulative cooling and heating load index of the model before and after the energy-saving renovation.Considering the time value of funds,the dynamic investment payback period is selected as the evaluation index of the economic benefit of energy-saving renovation projects,and the economy of energy-saving renovation schemes is analyzed and compared.On this basis,combined with the analysis and simulation results,the paper puts forward suggestions for building energy saving transformation in rural areas of eastern Henan Province,provides theoretical basis for large-scale energy saving transformation of rural residential buildings in eastern Henan Province,and contributes to realize the goal of“double carbon”.
