严寒地区农村住宅建筑节能评价标准研究OA

In view of the issues of high energy consumption and inadequate adaptation of energy-saving technologies in rural residential buildings in severe cold regions in China,this paper aims to establish an energy efficiency evaluation standard tailored to rural geographical characteristics and socioeconomic conditions.Field investigations and case analyses reveal a significant correlation between heating energy consumption(more than 60%)and thermal defects in building envelopes(e.g.,uninsulated walls,singlepane windows).Consequently,a hierarchical evaluation system integrating"heating energy consumption+structural performance"is proposed.Three energy-saving tiers are defined:TierⅠ[heating energy consumption≤160 kW·h/(m2·a)],TierⅡ[heating energy consumption≤110 kW·h/(m2·a)],and Tier Ⅲ[heating energy consumption≤65 kW·h/(m2·a)],supported by a"data-structure-classification"evaluation path.The paper further proposes an adaptive standard for the construction dimension,adopts correction rules such as orientation deviation compensation,local thermal insulation enhancement,window-to-wall ratio limit correction,and dynamic correction of energy consumption limits,and then verifies the rationality of the standard through the case of an energy-saving house in No.13 Village of Shangyi County.This work fills a research gap in rural energy-efficiency evaluation systems for severe cold regions,providing both theoretical foundations and practical tools for energy-saving renovation of rural dwellings under the goals of"carbon peaking and carbon neutrality".
