Being from California, I can tell you that we utilize ASHRAE 90.1 for
compliance since it is less stringent than the local state code.  For EAp2
and EAc1 you do have the option of utilizing either or.  LEED does state
that IF you do utilize anything other than ASHRAE it has to be more
stringent.

Hi All,

 

For LEED 2009, in relation to EA P2 (Minimum Energy Performance) and EA C1
(Optimise Energy Performance) can anyone confirm whether the local code must
be applied to the baseline building, if local code is more stringent than
ASHRAE 90.1-2007?

 

For other credits, LEED is clear that compliance must be shown by applying
the more stringent code but for EA P2 and EA C1, it ambiguously states that
"If the project is using a computer simulation, adhere to Appendix G of
ASHRAE 90.1-2007 or equivalent local code". 

 

Any advice appreciated if you have worked on any projects where local code
is more stringent than ASHRAE 90.1.

 

Thanks in advance,

 

Nancy Zikri
