[Bldg-sim] HVAC system for semi-heated space under LEED

[Jeremy Poling]

Just had this comment from a reviewer - the ASHRAE 90.1 handbook
explains this (it was page G-21 in the ASHRAE 90.1-2004 Handbook, but I
don't have the 2007 handbook to tell you that page number).  For a
semi-heated space, the baseline building models only the heating portion
of the system.  For an unconditioned space, the baseline has no system
modeled (any energy use is a penalty in the proposed model).
Conditioned spaces must be modeled based on the systems designed and the
baseline system per Table G3.1.1B; however, where a heating or cooling
system is not designed the proposed model must use the same system as
the baseline respectively (heating or cooling).

 

The semi-heated space heating system would need to comply with the
baseline system provisions for heating systems in Appendix G for the
baseline model and the proposed system would be modeled as it is
designed.

Assumption validation if you please ;^)

 

Under LEED, the HVAC system type for semiheated space 

should be the same in both the baseline and the proposed 

buildings, correct?

 

Thank you in advance!
