Heating and Cooling Energy Use Discrepancy

[cdavid]

I am experiencing a discrepancy with the heating and cooling energy use in the output reports from my WUFI Passive model. The Passive House Verification Report produces different results than the sum of the monthly heating and cooling energy use in the Passive House Site Energy Monthly Report. Excerpts from both output reports are attached. Results from the two output reports are summarized in the table below. In addition, I calculated the heating/cooling energy using the “Specific Heat/Cooling Demand Monthly” from the Verification Report using a COP of 4.76 for both heating and cooling.

Is there a different calculation methodology used for the two reports, or is there an error in one of the output reports?

Also, Renewable Electricity Production is not being captured in the Site Energy Monthly Report.
