algorithmic modeling for Rhino
Hi,
I got a question relate to ASHRAE 90.1-2010 Wall Construction from the EP Construction Library. I found out that the U-value from the EP Library does not match with ASHRAE 90.1-2010 exactly (for example, for Climate zone 1 Extmass Wall, EP Library offers U=0.649, whereas ASHRAE requires max 0.580 using IP Units).
The other question is that is the library updated to ASHRAE 20.1-2013?
Thanks!
Best,
Rufei

Hi Rufei,
Thanks for reporting this. The libraries are from OpenStudio standards.

You can check the details in GoogleSheets. Let us know if we're making any mistakes.
Do you mean ASHRAE 90.1-2013? Here are the standards that are available. We can update the libraries for the next release.

Hi Chris,
Thanks for your detailed explanation, that makes a lot of sense. Now I understand why the EP Construction has a higher U-value than the code. But I got one question for ASHRAE 90.1-2010 Extwall Mass Climate zone 7-8, the U-value is 0.054, but the code is 0.071, should I change R-16.84 to R-11.2 in order to make a U-value of 0.075?
Best,
Rufei
Hi Mostapha,
