[Bldg-sim] SPAM-MED: LEED NC: Existing or New Building

[MatthewRLarson at Eaton.com]

We have always used a pro-rated point scale based on floor areas as Kyle
describes for USGBC and it has never been disputed.

 

Thanks,

The CaGBC allows using a pro-rated point scale based on the relative
floor areas of new and existing.  Not sure if this is the same for
USGBC.

You use the existing building criteria for % and points in LEED if your
existing portion is greater than  half of the whole project sq.ft.
(existing + addition).

Yes, I agree that i should use the existing envelope for the existing
conditions of the existing building and the ASHRAE Min for the new
building.  But it comes down to whether EA Credit 1 follows the new
building % or the existing building %.  it is a 2 point difference that
could effect strategies for saving energy later in the design.

The baselines for the existing portion are what is there now.

 

The baselines for the new portion (addition) are ASHRAE definitions.

 

This should help considerably in your overall energy efficiency gains.

 

It all comes down to % new vs. % existing, on how much you can gain.

I have a unique situation where the architect is taking an existing
building and majorly renovating it (definition of major per LEED is
HVAC, envelope and interior spaces) and then building an addition which
is roughly the same size of the existing building, give or take a 1000
sqft.

 

Has anyone run into this before or have any insight that might help me
explain which avenue to take to my boss?  I am currently thinking new
building, but if it was existing then that helps me even more.
