WebAug 7, 2024 · Common units on the F-factor are Btu/ (h•ft•°F). To estimate the heat being transmitted from an entire concrete slab-on-grade floor, the F-factor for the slab is simply multiplied by the slab’s perimeter length and by the difference between inside and outside building air temperatures. WebOct 31, 2024 · The F-factor accounts for the edge treatment since this is where most of the heat loss occurs. Think of it like a whole assembly U-value of sorts. Some software like eQUEST uses this value. A U-value can be used in software where the F-factor is not used. Just apply the U-value to the correct areas of the slab. Webedge depend upon whether the slab on grade is 1) monolithic with a grade beam, or 2) supported on grade and independent of the foundation wall.
