[Bldg-sim] Which LEED with which ASHRAE ?

[Leadbetter, Keith]

We are currently working on two dorm projects that fall into this gray
area of LEED. 

ASHRAE 90.2 is the appropriate standard for these types of buildings.
However, no reference to 90.2 is made in the LEED NC v2.2 manual. We
were told by a LEED NC course instructor that the buildings cannot be
certified under LEED NC v2.2. His reasoning is that since ASHRAE 90.1 is
not applicable, the buildings cannot meet EA prerequisite 2. 

Also, the LEED NC v2.2 manual states: 

"All commercial buildings, as defined by standard building codes, are
eligible for certification as a LEED for New Construction building.
Commercial occupancies include (but are not limited to) offices, retail
and service establishments, institutional buildings (libraries, schools,
museums, churches, etc.), hotels and residential buildings of four or
more habitable stories." 

Most standard building codes define 3 story dorms as residential
buildings.

The owners of our buildings have decided to register the projects in
order to get an official credit interpretation ruling from the USGBC. We
hope to have an official answer within the next few weeks.

Standard 90.1 defines "low-rise residential" as " .... multi-family
structures of three stories or fewer above grade...", so 90.1 will not
apply.  Standard 90.2 will be your choice.

Hi Colleagues, 

I have here a group of 7 buildings in the same project. They are all
identical, except for orientation. 

The buildings are multifamily residential units, with 3 floors and a
basement each. They are existing buildings being renovated, and I am
wondering which version of LEED should apply (LEED for New Construction
and 
Major Renovations, LEED for Homes, ...)? 

Also, should I use ASHRAE 90.1 or ASHRAE 90.2 for the Baseline? 

Thanks.
