The Center of Glass (COG) U-factor for a glazing system is height dependant in ISO15099. The default height for calculating glazing systems in the Glazing System Library is 1 meter, you can change this default under File, Preferences, Glazing System Height. If you place a glazing system in a window (with frame elements) in the Window Library, it automatically recalculated the Center of Glass U-factor for the real height of the window. So the first solution (changing the default) is only needed if you only calculate Center of Glass numbers in the Glazing System Library.
