[Equest-users] Heating energy backwards

I looked at your file. If you look at the cfm's for each zone, the proposed
zones have more cfm than baseline. If the cfm is more than required, it
leads to more reheat energy also - since you have min flows in the 30-40%
range. You might want to check that or see why the baseline cfm numbers are
lower than proposed (since lighting is reduced to almost half in proposed).
Hope this helps.
