温和地区某近零能耗办公建筑工程实践
Practice of a nearly zero energy office building in temperate zone
摘要：
位于温和地区的云南省具有建筑能耗低、可再生能源丰富的天然优势,是发展近零能耗建筑的理想区域,但当前缺乏工程实践与技术体系支撑。以曲靖某钢结构装配式近零能耗办公建筑为研究对象,通过高性能围护结构、无热桥设计、可再生能源综合利用等技术,探索适用于温和地区的被动式节能与主动式产能协同路径。项目实测数据显示,建筑本体节能率达到51.44%,可再生能源贡献率达100%,预测年减少碳排放量约2.2 t。该研究验证了钢结构装配式技术与近零能耗建筑目标的兼容性,并形成了适用于温和地区的技术路线,可为云南省建筑领域碳达峰提供实践参考。
Abstract：
Yunnan province, located in temperate zone, has the natural advantages of low building energy consumption and abundant renewable energy, making it an ideal area for the development of nearly zero energy buildings, but it currently lacks engineering practice and technical system support. Taking a steel structure prefabricated type nearly zero energy office building in Qujing as the research object, through technologies such as high-performance envelope structure, non-thermal bridge design, and comprehensive utilization of renewable energy, the synergistic path of passive energy saving and active production capacity suitable for temperate zone is explored. According to the measured data of the project, the energy-saving rate of the building itself reaches 51.44%, the contribution rate of renewable energy reaches 100%, and the annual carbon emission reduction is expected to be about 2.2 t. This study verifies the compatibility of steel structure prefabricated type technology with the goal of nearly zero energy buildings, and forms a technical route suitable for temperate zone, providing a practical reference for carbon peaking in the construction sector in Yunnan province.
