建筑外窗的热工性能及其节能标识方法的研究

Study on Thermal Performance and Energy-Saving Marking Method of Building Exterior Window

摘要: 建筑外窗节能标识是能效标识时代下的产物。本文主要从外窗的传热系数、遮阳系数、空气渗透率以及可见光透射比四大性能参数入手，阐述了外窗节能标识的主要内容，并对外窗节能标识的等级划分作出了初步构想，这于超低能耗建筑的研究有一定的参考价值。

Abstract: The energy saving labeling of building exterior window is the product of the era of energy efficiency labeling. In this paper, mainly from the external window of the heat transfer coefficient, shading coefficient, air permeability and visible light transmission ratio of the four performance parameters, the main contents of the development of energy saving logo are described. The preliminary scheme assumptions are made on the classification of the energy saving logo of the outer window. This will have a certain reference value for research of Ultra-low Energy Buildings.
