[Equest-users] F-Factor of ASHRAE 90.1

[James Newman]

Omar,

Look in Appendix A in ASHRAE 90.1 to figure out what construction you need to meet the appropriate F-Value.

Subject: [Equest-users] F-Factor of ASHRAE 90.1

Dear all,

I read numerous forum discussions and articles about the F-factor. My question is much simpler!

For LEED purposes, ASHRAE 90.1 requires the F-factor for the unheated slab-on grade floor in climate zone 3 to be F-1.264

I do not have insulation in my project.

I go to my floor construction makeup in eQUEST, and I have to enter the U-value.

The question is: How can I transform the F-1.264 to a U-value that I can enter into eQUEST?

Many thanks,
Omar
