JGJ/T 151-2008 Calculation specification for thermal performance of windows,doors and glass curtain-walls

Scope

This specification applies to the calculation of the heat transfer coefficient, shading coefficient, visible light transmittance, and condensation performance evaluation of doors, windows, and glass curtain walls used in building enclosures. The calculations specified in this specification are conducted under the assumption that the air infiltration rate of building doors and windows and glass curtain walls is zero, and the steady-state heat transfer calculation method is used. The indoor and outdoor thermal boundary conditions of the building doors and windows and glass curtain walls used in actual projects shall comply with the requirements of the corresponding building thermal design standards and building energy-saving design standards. In addition to the parameters provided in this specification, the thermal calculation parameters of the materials used in building doors and windows and glass curtain walls shall also comply with the provisions of the current relevant national standards.
