[Equest-users] ERV Impact

Hello all. After finalizing my building and obtaining what appeared to be reasonable output, I removed the ERV devices (modeled at 85% efficient cross-flow air to air heat exchangers) from the model to ascertain the energy savings attributable to those devices.
And my total energy consumption went DOWN over 6%! Inexplicably, 'space cooling' and 'pumps & aux.' energy consumption has decreased by a far larger amount than 'space heating' increased. I would have expected both of those values to increase along with the 'space heating' energy consumption (which did increase).
Anyone have any idea why that might be?
