[Equest-users] 90.1 and Appendix A Materials

[Adam.Boyd at CH2M.com]

A while back I developed an INP file that contained all the baseline constructions for every climate zone. If you've got the ASHRAE Fundamentals handbook for looking up material properties, this was a pretty routine process. First create the new materials/layers/constructions in detailed edit mode, Appendix A has some detailed descriptions on what those should be (see A3.3.1 for steel framed wall). Next open the inp file and delete everything except the materials, layers and constructions. You can then import that inp file into any project using the eQuest import function. I've attached the file I created for this and just ask that you let me know if you find any mistakes!

I've been considering creating a similar file with the ASHRAE recommended schedules from the 90.1 User's Manual, but not sure if this would be as useful.

Paul,

I've been browsing through the ASHRAE DOE-2 files since receiving your email. I believe I have been following the same rabbit trail that Nick has so it would be great to have canned constructions. Can you explain the best method for importing the ASHRAE constructions into a model? I assume the edit must be made in the INP file. I typically try to avoid editing the INP file since my knowledge of the "code" behind eQuest is limited.

Thanks

Nick,
The DO2.1e input files available as part of the 90.1 User's Manual rely on the DOE2 library of construction materials.

Has anyone invested the time to create or otherwise stumbled across an *.inp file that contains the materials defined in Appendix A9 for easy import/use?

I had a model reviewer (not USGBC) who was unsatisfied with the material thermal properties in the default DOE2 library.  I ultimately went through the enormously entertaining exercise of defining materials with matching prescriptive R-values, while still using library data to retain appropriate thermal massing properties to avoid construction errors from weightless constructions.

This was an isolated case, but I could see such a file being a very handy resource for most modelers, particularly if it contained the contents of Tables A9.2A and 9.2B to pull the effective insulation/framing properties into our custom construction layers.

If this is flying over anyone's head who's interested, attached is a partial example of what I'm talking about - if you click File à Import File... and navigate to this file, you'll have a couple defined materials ready to access for your project within seconds - conceivably everything within 90.1 if someone had the time to invest...

On a related note... and I should have asked before, but does Section A9.2 possibly exempt the rest of Section A9 for eQuest users who rely on unmodified default library entries to define their custom envelope constructions?
