[Bldg-sim] LEED Energy Model - 90.1-2004 Appendix G and Local Code

[Robby Oylear]

I've successfully claimed lighting energy savings for tenant improvement
areas of Core & Shell projects subject to the Seattle Energy Code which
would require the tenant improvements to be subject to a LPD that was more
stringent than ASHRAE 90.1.  Your approach sounds reasonable.
