The　design　of　windows　significantly　affects　the　energy　consumption　in　buildings.　To　figure　out　the　impact　of　various　window　parameters　such　as　window　form,　frame　material,　glazing　layers,　and　Low-E　coating　on　the　energy　performance,　3407　products　were　collected　from　the　windows　acquired　China　fenestration　energy　efficiency　labels,　which　were　divided　into　18　window　types　according　to　different　window　parameters.　Four　models　from　Canada,　the　U.S.,　Europe,　and　Denmark　were　used　to　calculate　the　energy　rating　of　the　surveyed　windows.　Results　show　that　non-TBA　windows　with　low　U-value　can　reach　better　performances　in　the　heating　season,　while　windows　with　Low-E　coating　which　have　low　SHGC　can　reach　better　performances　in　the　cooling　season.　Accordingly,　different　factors　of　window　types　need　to　be　comprehensively　considered　to　improve　the　energy　performance　of　buildings　in　future　designs.　©　2023,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.
