Hi,
I wanted to work based on ASHRAE 90.1: 2010 for my simulations and am wondering how the numbers in the construction set library have been considered. Based on appendix G of ASHRAE 2010, a non-residential steel framed building’s exterior wall needs an R-value of R-13 + R-3.8 c.i. while the construction set library shows the R-value of 12.33.
I am a little confused if I am on the right track. I appreciate your help.
Thanks,
