Reduction in energy relates directly to EAc1 and can be accounted for in that credit. No ID credit would be available for reducing peak load.

Second on Robert's comment.? That is not enough to get an ID credit.?

On this same note, are there any worthwhile ID credits related to energy or energy innovations? I'm sure I can look into it, but half the time other ID credits see pretty far-fetched or too project-specific. I heard mumblings a while back about pre-wiring/designing/stubbing or space-allocation for future renewable energy (much like maximize open space - although in this case reserving infrastructures and space for equipment, not native plantings).

Much thanks

Hopefully you can use a time-of-day or demand rate schedule from the local
utility in place of the state average pricing, which will give credits to
your proposed design for demand management -- depending on the difference
between peak/off-peak from the utility, and the other large demand users in
the building of course.

As another poster or two mentioned, the ID credits won?t cover those items
included in existing credits ? except in the case of exemplary performance.
You don?t mention if this is the 11th EAC1 credit your are pursuing, you may
have a chance then?

Or else if you can get a letter from the utility talking about how your
demand management strategies have benefitted the local grid, even though no
cost savings is associated with the measures on-site due to the tariff in
place.

RE: innovation in design credit for reduction in peak energy load

Has anyone applied for and/ or gotten an innovation in design credit for
reduction in peak energy load for any version of LEED? We're working on a
project under LEED NC v2.2 and have significant reduction in lighting load
during peak hours by using solatubes.

Please provide any contact info and details if you can.

I appreciate the assistance. It seems like the energy model can be
manipulated to show the project savings during peak times and that would be
enough information needed for a submittal to the GBCI.

THANKS for being LEEDers!!

Keeping in mind that the whole point of ID credits is to be
"innovative", I would personally like to see more effort going into
reduction of plug loads. We generally just shrug our shoulders and
assume there is little we can do about that big chunk of energy that we
model identically between our base and proposed models, but that is
perhaps the biggest opportunity for further energy savings once
envelope, lighting, HVAC and DHW use are optimized. Energy display
kiosks and related educational efforts can be attempted for ID credit,
though I'm not sure how often points are granted. I'd love to hear about
some of the creative ways to tackle plug loads that people have come up
with. Don't assume clients won't hear you out and be receptive next time
you present an innovative idea at a LEED Charrette.
