[Equest-users] Actual Building Energy Cost

[B. Fountain]

Much of the discussion on this so far has been about modelling existing
buildings.

If your situation is that you are modelling a new building and using
"default" (MNECB or A90.1) schedules, plug load values etc. Then the
actual building operation could be 50% higher than the model is
predicting.  The difference will be in the occupancy, the schedules and
especially building operation and occupant behaviour.  All of these are
hard to quantify at the design stage.
