[Equest-users] Floor Slab F-factor

[Routh Consulting Engineers]

Could someone please help me with how to input or figure out what the
F-factor is for slab-on-grade floors? I've just input floor areas through
the wizard and selected the type of foundation insulation I have from the
drop-down lists. I have received a comment back from the LEED reviewers to
explain what I have and how my baseline case uses the unheated floor slab
F-factor of 0.73. Several of my thermal zones are interior spaces which have
a concrete floor with Earth contact but no exposed perimeter, but I do have
Earth contact floors in all of my zones so there is supposedly heat loss
from all of them. Any help with this would be appreciated.

 

Thanks,

 

Rick Routh
