I am doing energy model for LEED for Interiors 2009.
We work on a project that occupies 2 floors of a 7-story building. The
building has already got LEED for Core and Shell . Energy model of the
building was done using ASHRAE 90.1 2004 Appendix G. I am
using Appendix G of ASHRAE 90.1 2007 for LEED for interiors.
If my project has common HVAC system with other floors, how does the
model look for the baseline case? Do I have to model 2 stories of the
building ( my project) as a stand-alone building by AHSRAE 90.1 2007 and
other floors have to be modeled by AHSRAE 90.1 2004 ?
If I don't have enough information from Core and Shell design, can I use
only two alternatives ( actual and baseline design) for submission or I
have to submit 3 alternatives in any case?
Thank you,
