[Bldg-sim] 90.1-2004/2007 Baseline Question

[Zoeteman, Mark R.]

Nick,
Appendix G indicates Baseline Building "Floors" are to be Steel-joist. Refer to Climate Building Envelope Requirement tables in Section 5 and use U-factor for Steel-joist Floor for your climate zone.

Subject: [Bldg-sim] 90.1-2004/2007 Baseline Question

I've stumped myself!

When building a baseline model using 90.1-2004 or 2007, what envelope construction properties should we use for floors exposed to the exterior?

I'm currently planning on the "if all else fails match the proposed" route, but does there exist any guidance from ASHRAE or other sources regarding what the baseline case would be for such envelope elements?
