NC-2009 EAp2:Minimum Energy Performance

Updating the LEEDOnline form after being accepted

Dear All, If the USGBC awards 4 points under EA Credit 1, but then the design team decides to add significant lighting to the project which will increase the Proposed consumption (and consequently award 3 points), does the team need to "Appeal" the credit for this change? I.e., pay some $800 for an already approved credit in order to decrease the number of points?! Can't we just communicate with the GBCI through their website and ask to update this issue? What would you guys do? Thanks!

No need for an appeal. Did you do a split D/C submission or a combined submission? If split and EAc1 was awarded in the design phase you can resubmit in the construction phase noting that something changed during construction. If combined contact GBCI through their web site and request the update.

Thanks Marcus! It's actually a split. But if it were the other way around and we wanted to claim additional savings after they have awarded the credit (the Electrical engineer decided to lower the lighting to get more points), we will need to appeal, correct? Thanks.

I think that if you wanted to add a point after the review was complete and the certification had been accepted you would have to pay for an appeal.

Oh so we would need to appeal only if the LEED Certification has been awarded? But I'm thinking in terms of GBCI's perspective, if they spend time reviewing a big thermal model and award the points, then the design team, assumingly, shifts from DX-Split units to more efficient VRV units, the whole model will change (at least everything related to Heating & Cooling). I don't think the GBCI would be happy to review again this big complicated model, for free!

Assuming you submitted EAp2 in the design phase and it was approved in the design final review, any changes that happened in construction that affect the results are supposed to be resubmitted in the construction review phase. This hold true for all of the design phase credits. Yes the reviewer will not be happy about it but they are obligated to review it again in the construction review phase as part of the review process. This review should not be nearly as extensive as the first one since it will be limited to fewer issues. This resubmission only gets one additional review, not two, so make sure to get it right! For this reason we almost always defer the energy model to the construction review phase so we do not have to do the final model twice.

Great, thanks Marcus! I'm assuming this applies to any design credit submitted & awarded during Design Review.

Yep that is my assumption too.
