Nominal Resistance (Flat R-Value) in lieu of k-value (Thermal Conductivity)

Hello,

 

I am new to engergy modeling in Revit and when I was trying to set up materials, but the Thermal Properties, while they go very in-depth with setting like Electical Resistivity, they also feel limited in their flexibility. I want to create a material for my stud cavities (e.g. a fiberglass batt) however it seems like I have to use Thermal Conductivity to calculate the R-Value by thickness. This is great for my Rigid isulations like Rockwool which is 4.2 per inch, but fiberglass batt is R-19 period (in my zone) doesn't matter if its in a 5.5" stud or a 3.5" stud the R-value is always R-19.

 

Is there a way to change the thermal properties so that it calculates the Nominal Resistance instead of Thermal Conductivity or am I going to have to duplicate materials for each stud cavity thickness? Ideally I would have one material for metal stud and one for wood stud (simply to account for the thermal bridging), but I feel like duplicating those 3-4 times each for each stud thickness seems like overkill.

 

Also, if anyone has any good resources to help me learn evelope energy modeling in Revit, that would be much appreciated!

My bad, I reposted on the Insight Forum. I figured it was Revit Materials so it went here

No worries.

 

Look into Conceptual Types.
