China Fenestration Energy Efficiency Performance Labeling is a kind of informational identification, objectively representing energy-saving performance indexes of standard sizing doors & windows such as heat transfer coefficient, shading coefficient, air permeability & Visible light transmittance.
To guarantee energy-saving performance of doors & windows on building and improve building energy utilization, China Fenestration Energy Efficiency Performance Labeling was enforced on 29 Dec. 2016 according to Regulation of China Fenestration Energy Efficiency Performance Labeling Pilot Project issued by former Ministry of Construction of the People’s Republic of China.
