You can find a paper that outlines a procedure we use for office buildings at "eslsb5.tamu.edu". Go to reports, then go to ICEBO papers, and get the 2005 paper on commercial buildings.
EnergyPlus has a similar capability--an example file generator on the E+
web site. It allows you to create, run, and get results back for three
levels of 90.1--
1999, 2001, and 2004 along with the recent ASHRAE 30% guide for small
buildings (30% less than 1999). We're looking at adding 189 as well once
that gets to public review.

One of tasks I find myself doing repeatedly is creating budget cases, both
for compliance and performance modeling.
I've been wondering if automated software could take a design building and
automatically create the budget case.
I'm currently modeling in VisDOE and eQuest and may soon expand to TRNSYS.
Has anyone seen such add-ons for:
- ASHRAE 90.1-2001
- ASHRAE 90.1- 2004 ECB, and / or
- ASHRAE 90.1-2004 App. G?
eQUEST comes with a "compliance engine" which will automatically
create the reference case; but the reference building rule set for
ASHRAE 90.1 has not been created (or has not been publicly released)
that I am aware of. See volume 5 of the eQUEST documentation.
Too bad your buildings are not in California. Both EnergyPro (Gabel
Associates) and eQuest model a Title-24 Base case building with what you
give it as the actual building. It changes the schedules as well to
Title-24.
EnergyPro is currently approved, with eQuest due for approval by the
California Energy Commission in a month or so.
The only other potential I know is the effort by the Oregon Energy Trust
to get a version of eQuest to bless the Oregon version of
ASHRAE-90.1-2004. Since 90.1 is a Standard, many states reference this
Standard, then add their own "tidbits" to it as they see fit. So it
would be difficult to modify the standard for each case.
Having done work through the Utah Energy FinAnswer program, I know the
effort you speak of trying to create a base case building.
Email Jeff Hirsch at jeff.hirsch at doe2.com to see what might be "cooking"
with future eQuests.
Also consider joining BSUG (Building Simulation Users Group), a group of
modelers who met by web cast once a month to discuss such issues.
Contact kathryn.j.henderson at saic.com in Portland, Oregon, who
coordinates the seminar, once a month.

I have heard that FSEC's energygauge software does it - havn't tried it
myself.
