ALL LED project

Nena, have you checked LEEDuser's guidance on that credit page? I think this question has been addressed there or in the forum.

I submitted an all LED CI project, and had it accepted without any comments. Using the sample template from EBOM, we only filled in the first section under "Establishment", the "Table MRc4-1. Lamp Purchasing Plan", and supplied the related cut sheets, for both the LEDs, AND for their fluorescent comparisons (which was extremely time consuming for a 300,000SF project, by the way). We checked the alternative compliance box at the end of the template and provided the following text: "This project is attempting this point as an ID strategy for our LEED-CI project. Since we are not an EBOM project, we do not have a performance period; we have left all fields related to performance period data blank. Also, our project does not include any outdoor areas, so we do not have any outdoor fixtures. Our project contains only LED fixtures. There are no compact fluorescent or incandescent lamps anywhere in the project. Therefore, all lamps reported contain 0 mercury. All product cutsheets have been provided for reference. Linear and compact fluorescent equivalents are provided for efficiency comparisons. There are instances where those comparisons do not apply (based on fixtures being completely custom, or products that do not have a comparable fluorescent version). Those types are indicated on the cover sheet of the fluorescent comparisons." Hope this helps. I'd think an NC project would be the same. We have used this example on several NC projects since it was reviewed, we just haven't had those NC projects go through review yet.

With zero Hg-containing lamps, this should be a slam dunk. I've written ID credit proposals in the past using the installed lamps (not the purchased lamps as used in O+M) and provided a calculation to show the pico-grams per lumen-hour (landing under the 80 or 100 threshold, depending on which version of the O+M credit I was referencing). I'd suggest including a simple narrative stating that you use zero Hg in lighting equipment, and concluding that this empirically proves compliance with your proposal (keep in mind an ID credit needs to include proposed requirements, which should mirror the O+M credit to the extent that it is applicable). That said, empirical proofs haven't always been received as coherently as I would have hoped by some review teams, although in this case it would be hard for your reviewer to miss that zero total Hg means zero pico-grams per lumen-hour. Good luck!

Emily Reese, thank you so much! Your post was most helpful. I am in the exact current situation with a LEED-CI project pursuing the ID LEED EBOM MRc4 credit. Thanks!
