DesignBuilder does not use certain inputs, depending on the way you have configured HVAC calculations in the Model Options tab (the little wrench icon on the tool menu).
If the HVAC tab input is highlighted in green, the input is not used.
I'm not sure, from your description, where you are changing COP - so that's the best I can do at the moment.
