[Equest-users] Big question on ASHRAE compliance

I am working with our company's LEED specialist to do the energy modeling for a project for LEED-NC 2009 certification.

The energy modeling obviously fulfills the EAp2 minimum energy performance requirements.
Ever since we've started I've been using ASHRAE 90.1 (2013 version) because that's what he said we needed to match for baselines.

I think he may have been wrong.  When I asked him about it he said I was correct and that 2007 should be the standard.
I'm not confident he knows and I don't want to move forward unless I know with certainty.

After doing some research, and with the model nearly completed, I'm thinking ASHRAE 90.1 (2007) is what we needed to adhere to for compliance???!

Is there anyone who can verify which version of ASHRAE is the current standard for applying for LEED-NC 2009 cert?

LEED users website states that 2007 is the current compliance method for LEED-NC 2009.


If we don't have to model to the stricter energy modeling standards of 2013 ASHRAE, why would we?
No reason to show the additional compliance if it isn't required for LEED cert., am I right?

Thank you!
