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?
