[Equest-users] Indoor arena suggestions/tips

[Matt Hein]

Has anyone been able to capture savings from a natural ventilation 
design for LEED 2009 NC?  (I interpret that G3.1.1.b prevents this.)

Glancing over Appendix G I see something that doesn't seem very 
encouraging of 'green' design: (not to say that it discourages)

  * G3.1.1.b says, "All conditioned spaces in the proposed design shall
    be simulated as being both heated and cooled even if no heating or
    cooling system is to be installed ..."

It seems like there should be some way to encourage natural ventilation 
design by accounting for the energy savings.
I suspect I'll approach this by setting a high Tstat value (100 F) and 
using the exact same cooling configuration for proposed and baseline so 
the savings are null. Well, maybe I can get some fan power savings.
