[Equest-users] F-Factor of ASHRAE 90.1

[Omar Katanani]

James,

 

I did not understand the appendix exactly! Isn't there 1 value for
converting between F-value and U-value that anyone can help me with?

 

Thanks!

Omar

Omar,

 

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

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
