摘　　要：超低能耗建筑是建筑节能向更低能耗发展的新模式,该模式是通过优化现有的建筑节能评价控制指标,使建筑最大程度地降低建筑用能的能源消耗和损耗,最大限度地降低建筑碳排放的预设目标.通过对国内外现有超低能耗建筑及高效用能建筑技术开展调研和集成应用总结,结合河南省城乡建设领域高质量发展和“双碳”目标的迫切需求.以超低能耗建筑相关评价指标为依据,对围护结构在不同设计工况下室内环境参数和能效指标的目标进行控制计算,对设定的目标能效指标加以分析与评价.从材料选择、结构设计以及构造作法等方面对围护结构进行低能耗化设计及碳排放进行体系评价,提出低碳导向下的超低能耗及高效用能技术方案,通过控制建筑围护结构性能指标提高建筑的热工性能,构建节能-舒适-低碳的超低能耗化的围护结构体系,实现降低能源、减少建筑碳排放的目标.Ultra-low energy consumption building is a new model of building energy conservation,by optimizing the existing control index of building energy saving evaluation,aiming at minimizing the energy consumption and building carbon emissions.Based on the evaluation standard of energy-saving buildings,the indoor environmental parameters and energy efficiency indexes are calculated under different structural design conditions,and the calculated evaluation indexes are compared and analyzed with the set target energy efficiency indexes.The design scheme of building structure is further optimized from the aspects of building materials,structural construction technology and construction technical measures,so as to achieve the preset evaluation index target of building energy efficiency,and realize the quality optimization of building interior space and ultra-low energy consumption design.
