Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 18091-2000 "optical properties of glass curtain wall," compared with the GB/T 18091-2000, the main changes are as follows.
--- Standard name changed to "glass curtain wall light and heat performance";
--- Increasing the glass curtain wall solar thermal parameters of the technical requirements;
--- Transmission index increased color grading;
--- Adds rules limiting glass wall reflected light.
The standard proposed by the Ministry of Housing and Urban-Rural Development of the People's Republic of China.
This standard by the national building curtain wall windows and doors Standardization Technical Committee (SAC/TC448) centralized.
