摘要
建筑外窗作为建筑围护构件中最不节能的部件,包括传热系数(U值)、可见光透射率(T_(vis))、太阳热增益系数(S_(HGC))等在内的光热性能指标直接影响了建筑的能耗。为了更加全面地了解建筑外窗节能设计的关键技术,通过数据库资料详细梳理了前人的相关研究成果。研究发现:窗墙比、建筑遮阳、窗框、窗玻璃、气密性等是影响建筑外窗节能的关键要素;集成技术在外窗节能设计方面具有明显的优越性,能够极大提高外窗的节能效率;人的行为方式对外窗节能效率也会产生较大的影响。
The exterior windows of buildings,as the least energy-efficient component in building envelope components,have a direct impact on the energy consumption of buildings,including thermal performance indicators such as heat transfer coefficient(U),visible light transmittance(T_(vis)),and solar thermal gain coefficient(S_(HGC)).In order to gain a more comprehensive understanding of the key technologies in energy-saving design of building exterior windows,a detailed review of previous research results was conducted through database data.Research has found that window to wall ratio,building shading,window frames,window glass,and air tightness are key factors that affect the energy efficiency of building exterior windows;Integrated technology has obvious advantages in energy-saving design of exterior windows,which can greatly improve the energy-saving efficiency of exterior windows;The way people behave can also have a significant impact on the energy-saving efficiency of external windows.
