I've been reading around and from little bits and pieces of info it appears that the most objective parameter to compare the heating requirements of many (if not most) buildings of similar size and function would be energy per house size per heating degree day.
In the few places I've come across this, the units for energy were always kWh. While the size of the building can be given as just the floor area, it must be noted how this is measured - sum of internal floor area is easiest, since this is usually known. External "footprint" of each level of the building is slightly better, but still does not distinguish between single- and multi- level buildings (the latter will be losing less heat, all else being equal). The best way to "size" a building is to measure the area of all of its external surfaces - walls, floor and roof.
I know that this has already been mentioned here, but I just wanted to bump again;)
