Process loads - plug loads

Yes it is possible to claim savings credit but not as an ID credit. To claim credit the Proposed is modeled as designed and it is up to the project team to identify and defend a reasonable Baseline. Some sources of acceptable Baselines include Energy Star, COMNET, LEED Retail, etc. depending on the plug loads for which you are claiming savings.

Marcus, I agree that you can certainly propose a plug load savings program and then provide narrative and extraordinary calculations to support energy savings that could be claimed under EAc1, but in this case the question was if an ID credit could be claimed. It was my understanding that overall, GBCI was not tending to grant that kind of credit as an ID, since you are getting points under another credit. I know that traction elevators were granted an ID for a few projects, but I have heard that is no longer given.

Please let me know if I am wrong on this.

Yep missed those two letters Scott, thanks for keeping me straight. I edited my comment above.

The only ID credit for energy savings would be for exemplary performance unless there was some other benefit associated with an energy saving strategy that was not covered by an existing LEED credit.

Operational credits can earn BD+C ID credits. If you were able to focus this on having an effect in operations then maybe. I would try to be as comprehensive as possible so maybe beyond just plug loads. It is a challenge to basically write a new LEED credit from scratch which is what you would need to do. Be sure to structure it just like any other LEED credit including documentation. The reason that most folks just use an existing LEED credit, exemplary performance or something tried many times like green building education is that it is very hard to write a new LEED credit and requires a lot of effort for something that may get rejected. So think about it very carefully. Good luck.

Marcus always gives good counsel, and we do not have experiance with a "new" ID credit, but have had quite a bit of success with applying some of the EBOM credits to NC as he mentions. A few years ago, I had heard of a program that would push our energy use settings to all corporate computers and laptops, resetting them to something determined by the IT department. That always intrigued me as there are so many monitors and other devices around our offices today. Plug load is an area that needs more attention and more tools to affect energy efficiency, so I also wish you luck.

Hi Marucs,

Can we clam saving on Building plug load using energy star equipment for office space and dining area?

Such as the allownce for plug load for office buildinf 1.6 watt/sft and we try to make it it 1 watt/sft, in that case can we clain saving at concept stage? it is not for LEED certification, 

i have confusion, as i know , we cant claim saving on this, we need to make same in both models i.e Basleine and Proposed

Hi Marucs,

Scondly can we use COMNET or BEM Cyclopedia vlaue of 90.1 2016 (LPD) as reference to save time(avoid searching the wholes Table of 90.1 2016 or 90.1 2010)?

I'm confused by your questions. If it is not for LEED certification I am not sure why you are posting it here? That said your plug load allowances seem very high compared to ASHRAE or COMNET values. You can claim savings for Energy Star equipment in LEED following an exceptional calculation. You can't claim savings simply based on a difference in plug load power density, you have to compare the equipment expected to be installed in the project. YOu can certainly use COMNET for plug loads but not for lighting power density.
