[Equest-users] Input F-Factor for Slab-on-grade floor in eQUEST?

[刘宇]

Hi all,

 

ASHRAE 90.1 defines baseline slab-on-grade floor conduction by F-factor, but
it seems eQUEST uses U-factor to calculate ground (and perimeter maybe) heat
transfer (link to a construction like other surface type). There is a
“Slab-on-Grade F-Factor” box in <Underground Surface Properties> dialog,
but the value is not editable. Does anyone know how to input a known
f-factor for slab-on-grade floor in eQUEST? Many thanks.

 

Regards

 

Yu Liu
