Peak Heating Breakdown Seems Wrong

I am running simulations in Honeybee with ideal loads. When I then look at the breakdown of the peak heating load as reported by the inTable.csv file, it always seems unrealistically high, with the largest contributor being ‘Opaque Surface Conduction and Other Heat Removal’. Strangely, this value seems to be more reasonable when I use an HVAC system although I am not sure why it is different at all.

Any idea what is the source of this strange energy plus reporting?
