I recently submitted a model to the local utility company for an incentive.? Part of the buildings' first floor is slab on grade.
One of the comments I received back is that this erroneously shows up as an exterior surface and I should delete all the slab on grade floors in the component tree.? Doesn't seem right to me.

I did a few and it does reduce the overall energy consumption.? In the 3D model, no floors show, just open to the interior of the zone.
So is eQuest assuming that without this floor, there is no heat loss out the bottom of the zone?? Is this reasonable?

Thank you,?Paul Diglio
