Although I agree often in practice passive house occupants can and do use
wasteful appliances and end up with standard loads the answer you are
looking for us in the PHPP excel sheets. You use the internal loads sheet
to put in your fridge, lights etc. specific to the project.

I've seen papers written where developers refunded a deposit if the clients
bought energy efficient appliances. Have to admit seeing data on large
plasma tvs causing huge energy consumption as well.

If you don't have access to phpp please reply to me offline there is a
released copy that might have the data you want online I don't have the
link in front of me. Right now.
