Same as credit MR 2.2, except for percentage diverted (75% in Materials and Resources 2.2)
Divert 50%
Intention:
- Divert construction and demolition debris from landfills and incinerators
- Redirect recyclables back to manufacturing process
- Redirect reusable materials to appropriate sites
Implementation:
- Develop a construction waste management plan to at a minimum, identify materials to be diverted:
- salvage, refurbish, recycle, reuse
- Include:
- doors and windows
- salvaged flooring, paneling, cabinetry, beams
- recycled cardboard, metal, brick, acoustical tile, concrete, plastics, clean wood, glass, gypsum board, carpet and insulation.
- MEP (mechanical, electrical, plumbing) updated
- Exclude:
- soil, rocks, vegetation
- hazardous material
- Designate site in construction area for separation process
- Track recycling through construction process (general contractor to keep records i.e. receipts, of recyclable and waste diversion pickups)
- Diversion can include donation to charitable organizations as well.
- Calculation:
- Based on WEIGHT (lbs.) or VOLUME (cubic ft.)
Codes/Standards Applied:
- none
Extra Credit:
- divert 95% (instead of 50% or 75% as in MR2.2)
Submittal Phase:
- Construction (tip: all Materials and Resources credits are submitted in the construction phase except MRP1)

My LEED NC reference guide does not tell MEP should be excluded in this credit. Can you tell me where you found this information? Thanks.
Chi,
This is located within the text of the reference guide for MR1.1, MR2.1, and MR3.1. Are you sure you are using the correct reference guide? Which edition are you using? If you are using the first edition, it has since been updated. Thanks, and good luck.
Hi Pat,
I think Chi is right, the MRc2 does not mention MEP as excluded, infact the graph in the front of the MR section shows that MEP can be included as part of the construction debris. Thanks!
Sam
This is so confusing to me. The graph of my first edition reference guide (p.235) tells me MEP is included. But Pat is telling me the new version says MEP is excluded. I would like to see that page personally. Pat, do you mind to send me a copy (pdf or jpg file) of that page says it is excluded if this is not too trouble to you? I am going to take NC AP exam next Tuesday. It is an important information for me to know.
If you are too busy to do so, that’s ok.
Thanks.
Chi,
In looking at the matrix in the later versions of the reference guide, you are correct. There is an error on this page the MEP SHOULD BE INCLUDED. I apologize for the confusion, Chi. I think I got it confused with most of the other MR credits which exclude MEP – and it definitely makes sense to include MEP for this credit. My sincerest apologies, and thanks for catching that for everybody.
We will have two LEED projects under construction simultaneously, CS (core and shell) and CI (part of building occupied by the first tennant). We intend to submit MR Credit for Construction Waste Management on both projects. Do we need to have separate dumpsters for each submittal?
does an asphalt parking lot count as in this?
asphalt is included. check the sample table 1 under MR2 in v2.2, p. 258 and also the narrative under ‘considerations’. asphalt can be crushed and recycled and is well established.
Hi Pat,
I found the following quiz in the site of University of Florida. The given answer is,”The project is not eligible for LEED certification.” I think MRc1.1, c1.2, and c7 would be applicable. Am I wrong?
“A green-built fire station is being constructed out of a 1920s-era police station. The new building reuses 98% of the exterior structure of the old building and 40% of interior elements. It also intends to collect, store, and recycle glass, plastics, and metals. In addition, all wood purchased for the project will be FSC-certified, and the project team has made a large-scale effort to incorporate non-structural interior elements of the project, such as doors, that were unfit for use under the same circumstances, into decorative aspects such as trim. For which LEED points would the project be eligible?
I came across this same question also in my studies. The only reason I presumed that the project did not qualify is because they did not mention recycling of paper and cardboard, a prerequisite for LEED Certification.
Now I see how it is!! Thank you JD!
I need some clafification on a FSC Chain of Custody question.
In the implementation of MRc7 paet e.
As a contractor or sub contractor I can purchase directly from a FSC certified seller
but not from a reseller who purchased from a FSC who is not COC certified?
I’ve just received a bunch of roofing materials and products from trades. Does anyone know if any of these roofing products are eligible for any credits?
Hideo,
I took the same quiz and also failed. The reason the project does NOT qualify, is because the MRp1: Storage and Collection or Recyclables, is not met. It requires at a min. to recycle glass, plastic, cardboard, metal and paper, and in the question, they only recycled glass, metal, and plastic, BUT NO paper and card board. That’s why the project does NOT qualify at all, even those some of the credits look really good.
Those people are tricky. 🙂
From what you guys have read, does construction debris include food waste during construction. In order to get a “percentage diverted” you need a denominator or total amount of material hauled offsite. Would lunch garbage from construction workers be considered construction waste, or is it count only actual building materials…? any thoughts and backup would be appreciated!
I tend to think that the denominator is strictly composed of construction and demolition debris. Which, to me does not include lunch garbage. It does not even include soil, rocks, or vegetation. Why would food be more representative of construction debris than soil and rocks? They do not specify, but food is definitely not added to the denominator.
Can anyone help me with this? Thanks in advance
Which of the following is the largest component to construction debris going to landfill?
A. Asphalt
B. Wood
C. Metal
D. Drywall
Mark,
This very interesting article will give u the answer!
http://www.epa.gov/climatechange/wycd/waste/downloads/Analyzing_C_D_Debris.pdf
Good luck!
Thanks Omar, it is an interesting article indeed.
So I guess the answer is B. Wood.
YOU GOT IT MARK! When are u taking the test? I am scheduled for next week.Scary!
Mine is last week of march..still have 2 weeks left.it is scary.
Is it correct that doors and windows are included in MR c2 ? In the LEED Reference guide, salvaged doors and frames and windows are in MRc3.
Its true you can use them for either one, however you must pick one or the other. Any materials used to earn credit 3 cannot be used to earn MR credits 1,2,4,6, and 7.
Many questions from this section on my test. Look at the sample letter templates in this category for “required” documentation by the contractor. At least 2 questions buried “hazardous materials” responses in the answer options.
Pat-
Under implementation you say the calculation is based on weight (lbs) and volume (cubic feet). These are both correct, except the units of measurement in the reference guide are tons and cubic yards.
We are the designers for a major building remodel. If there are items removed that are taken by a private party for re-use, does that count as being diverted from the landfill?
Hi Karin, it is my belief that this is true, because you are indeed diverting from these materials going to the landfill. Usually, it’s going to be from a third party company anyways.
