[Equest-users] Question on LS-C report

[Robby Oylear]

It's likely that each buildings will have a different peak load which
occurs at a unique time during the year.  If the loads do not occur at the
same hour, the occupancy load will likely be different, and outside air
conditions may vary such that your infiltration load will also be different.

I'd say it is unlikely that you should ever see the occupancy and
infiltration related loads in the LS-C be identical between a baseline and
a proposed model.
