FAQs about MRc3 :

What if we don’t make any facility alterations or additions during our performance period? Is there anything we can do to earn this credit?

What kind of construction or renovation activities count as a facility alteration or addition? We had the building interior painted, does that count?

Which of the purchasing credits covers mechanical, electrical and plumbing purchases? Do I include them in MRc3?

Can I use the LEED-NC default of 25% recycled content for steel in our facility alterations and additions purchases?

EBOM-2009 MRc3:Sustainable Purchasing—Facility Alterations and Additions

Roofing Materials

I have a project that, in addition to other upgrades, is replacing the roof. Do all of the roofing materials need to be included in calculations for MRc3? I saw that this came up in another post several years ago, but wondered if anyone had any further input or review experience with this. Thanks!

Yes they do, but, be a little careful. This work along with 'other upgrades' might be seen as a LEED BD&C job, not a EB O&M due to the roof replacement.

Thank you for the response. I should clarify the roof upgrade. They are replacing the existing roof system from the concrete deck up. Does this still qualify as an alteration since it is not affecting usable building space? Also, do the same guidelines used in the NC-2009 Low-emitting materials credits (i.e., only adhesives/sealants/paints/coatings used inside the weatherproofing system) apply for EBOM-2009 MRc3? Thanks.

Jason. Ok, now we have more information, let's take another look. First, scroll up and read the first 4 bullets under 'consider these question when considering this credit'. Can you answer yes (or almost yes) to them. Now we come to the gray area. The work you are on is not a 'room', but IMHO you should be tracking ALL the materials being used and provide data and forms to cover the work. (It's over 5% of the total floor area I assume...this isn't a multi-floor building where the roof area is less than 5% of the total?). Now the difficult one...are you using more than one trade...again I assume you are? So the basics of the credit requirement are being completed and ALL the material should be accounted for.

Hi Jason, a complete roof replacement counts as a facility alteration/addition for EBOM.

Hi Barry,  Does this include all of the materials such as screws and nails? Or just the roofing component?

Hi Kelsey, sorry for the late reply. I'd include those in the total cost of purchases.
