[Bldg-sim] passive design performance rating?

[Aleka Pappas]

Hello All,
I'm working on a (LEED) project that is heated and cooled entirely with
passive strategies, and we'd like to claim energy savings for EA credit 1.
I would like to model the proposed building with the passive strategies,
prove that there are not excessive hours of loads unmet, and compare it to a
Baseline model with an HVAC system.  90.1 does say explicitly that it
doesn't apply to buildings that don't use electricity or natural gas,
though.  Is there another code/ rating system that applies to passive
buildings?  Has anyone ever applied Appendix G to a passively designed
building to show savings for LEED?

Thanks for your input.
Aleka
