Abstract:
The operation principle of heat gain transfered into cold load was represented, and the thermal performances of three most widely used glass curtain wall were introduced. Cold loads of an exhibition center glass curtain wall were calculated under eleven combinations using transfer function method. Taking 3 mm standard clear float glass as reference, energy consumptions of different combinations of glass curtains were calculated. Cold loads under different geographical locations, shading coefficients and heat transfer coefficients, orientations and latitudes were compared. Results show that in different regions, the main methods of reducing energy consumptions are selecting proper glass, selecting suitable wall-window ratio in different orientations, and setting shading device.
