[Bldg-sim] LEED 3.0 question

[Nick Caton]

Hi Mark,

 

"How does one model process loads...?":  Generally - equally in the
baseline and proposed models, unless you are providing documentation to
demonstrate more efficient process equipment loads/scheduling than a
baseline (which you should also define/document).  I've copied a
previous query below yours which should help - there's more discussion
in the archives if you'd like to pursue.

 

If you mean "how" as in "how using eQuest," then you'll need to give us
more info regarding which program you're using and what loads you're
trying to model.  On a related note, I'd advise avoiding posting the
same question to multiple listservs as not all respondents will keep
abreast of the current discussion.

 

"...is it not required?":  This is an interesting question... & one I
don't have an immediate answer to.  If the issue is that you cannot
document the process loads for lack of information, that's why the 25%
minimum figure exists, but that doesn't sound like your current
situation.  I think it's implicit that you should be modeling all energy
consuming process loads, and documenting any efficiencies against
industry standards per the above/below, but to outright exclude a
manufacturing process might require leaning on an existing CIR... you
may get others to chime in with their experiences if you can describe
the nature of the loads/building more specifically (auto factory
machinery?  Lab equipment?  Airport conveyor systems?).

 

Best of luck!

The question has come up, when pursuing Leed 3.0, how does one model
process loads (Manufacturing not Plug), or is it not required to be part
of the model

We have documented this on two projects - in both cases we had to
document what the industry standard for the process would be and then
how ours was more efficient.  One was related to conveyor energy usage
and the process integrator documented the expected savings based on
numerous other installations they had done over the past few years.  The
second one was the process energy associated with refrigeration -
through team member networking we surveyed approximately 200 owners of
buildings of a similar scope and use to document the baseline
refrigeration system that a building of that type would use.  Then we
documented how our system was different and more efficient.

 

In both cases this was approached with the alternative calculation
methodology of ASHRAE 90.1 and that section of the LEED template.  Hope
that helps!

Subject: [Bldg-sim] LEED Process Energy Reduction

 

Hello All,

 

I am currently working on several process intensive buildings. The
mechanical systems and corresponding control strategies that are being
designed are ideal for achieving 30%-40% savings in a standard office
building but I'm afraid that the common denominator, the high process
loads, will significantly reduce my projects savings. Has anyone
successfully submitted for a reduction in process load. If so, what/how
did you document the reduction?

 

Thanks for your time.
