Hi Jeremiah, you might want to take a look at the Building Component Library (bcl.nrel.gov). The construction assemblies that NREL uses to approximate the ASHRAE standards are available there in OSM and IDF formats:
The latest OpenStudio application allows searching for and downloading construction components from the BCL from within the application. The OpenStudio installer also includes Ruby bindings which can programmatically access the BCL. Finally, Alan Jackson has posted some Python scripts which can be used to convert the IDF files to INP format:
Hope that helps,
Dan

Subject: [Bldg-sim] ASHRAE code multiplier?
Dear list,
I am working on creating envelope libraries for ASHRAE 90.1 2010, 2007 & 2001 code vintages.
I have a copy of ASHRAE 2010 standard and users guide, and am wondering if there might be a general multiplier that could be used to back the insulation levels as well as U values down to the 2007 and 2001 levels. When I purchased the ASHRAE 2010 standard and users guide the ASHRAE rep I spoke with mentioned that I might be able to use a multiplyer for this. From what I recall insulation levels where raised by 16% for ASHRAE 2010 from ASHRAE 2007, but do not know if this 16% is actually the number or not and do not have any assumed numbers for other vintages or values. My use of this is for PCM modeling, sort of conceptual massing preliminary modeling & climate studies so strict code compliance is not necessarily required but would be preferred. I would prefer not to buy all of the individual standards if possible so wonder if such a multiplier might be reasonable. I would like to also do space type lighting codes & DHW (for internal gains) as well.. If anyone has insight it would be appreciated, and I also could share my finished work (in excel, energy plus and design builder formats) with anyone who wanted it..
Best regards-
Jeremiah D. Crossett
