[Equest-users] R values

[via Equest-users]

In detailed mode (or after hitting “complete” in the wizards), find your construction in the component tree under the “building shell” teab, and double click the construction for an overall U-value (inverse of R) and check out the layers tab for a comprehensive summary of the individual components’ thermal properties:

 

 

 

Regarding R-value units:  When in doubt, expect eQuest is using IP units, not SI.  In the USA we normally use R-values in the units ft2·°F·hr/Btu.  The conversion factor between IP and SI units for R-values is something between 5 and 6.  

 

Without knowing what material you’re referencing, I can almost guarantee something R-38 is in IP, since if it were in SI that would be something like R-200 to 240  in IP units (unlike any material I’m used to seeing in typical building constructions).

Hi all,

 

I need to know the R values of the constructions (doors, roof and Wall constructions) used in equest. How can I learn it?

 

Also, does a insulation material R-38 mean a insulation material with R=38 m2K/W?

 

Thank you

 

Kind Regards

 

Gul Nihal Gugul
