ASHRAE 90.1, 2010 and LEED

I would just like to know if it will be acceptable to use ASHRAE 90.1, 2010
standard for LEED 2009 projects.

I ask this because, the system selection for storages,toilets,etc. are
treated differently in the 2010 standard than in the previous ones.

It would be great to know if LEED would accept the use of 2010 standard.

Thank you.

Dear Vinay,

LEED 2009 specifies which version of 90.1 to use. I think it's 2007.

My general understanding is that 90.1-2007 and 2010 are two VERY
different animals. I'd be very concerned with EAp2 / EAp1 becoming
very difficult to document as they're structured around 90.1-2007.

Here's a question to those more familiar with 2010 that may help Vinay:

Is a "90.1-2010-compliant" design guaranteed to be
"90.1-2007-compliant," in a prescriptive context?
