[Equest-users] LEED Baseline for onsite cogeneration

[Nicholas.Caton at schneider-electric.com]

Hi Steve,

 

I think the answer will depend on a few things.

 

Probably good advice to plan for eventually submitting a
project/site-specific query with GBCI (though you may not need to).
First peruse the published guidance for LEED district energy systems
"Treatment of District or Campus Thermal Energy in LEED."  I and others
have referenced this as the "DES guidance" as well (may be helpful as a
search term).  

 

You'll want to review the whole thing, but there's an appendix towards
the back specifically addressing EAp2/EAc1 credits post-processing for
district/campus systems including cogeneration/CHP equipment.  I've done
this a few times over now (for projects on a district
heating/power-generation loop).  Sadly I've yet to encounter a project
that "cleanly" fits this guidance to a tee (just my luck probably...),
but if you take some time to digest what's there you might be able to
ask more direct and productive questions for clarification specific to
your project, if needed.  If this equipment is not on a district/campus
loop, you may be able to isolate/extract some simpler direction using
this as a framework.  

 

It *might* be as simple as doing nothing special for the baseline and
just lopping off an electricity credit at the end for your proposed case
based upon simulated output (if you are modeling the equipment
explicitly within the simulation).  Hopefully that's the case and
someone else can confirm ;).  Even in that simplest case you should
probably plan on developing a write-up for supplemental documentation to
summarize the pertinent equipment documentation & simulation inputs +
outputs.

Subject: [Equest-users] LEED Baseline for onsite cogeneration

 

Has anyone done a LEED project with an onsite microturbine used for
electricity generation and heat recovery for the hot water loop. 

 

Appendix G seems to state clearly that I can take credit for the waste
heat recovery. My question is if I need to have the microturbine in the
baseline,  but not use the heat recovery feature. Or if the Baseline
should just be standard electrical use on the main meter.
