FAQs about MRc1.1 :

How do exterior elements, such as a covered dock, get counted? Would that be considered a slab or exterior hardscape and not part of the building?

What building elements get included in this calculation and what can be excluded?

Should I base my calculations on plan or elevation?

How do you calculate the existing building structure reuse?

credit calculations for historic building

we are the GC on a 200+ yr old building being renovated as part of a LEED project (there's also a smaller SF new addition.)

the very significant building is over 200 years old and is in the historic french quarter and was home to two very well known families. The credit calculations for MRc1.1 do not take this into account. I feel that there are several significant features of the house that are being restored and reused that don't really seem to get their credit due under this credit. ie. an aeolian organ & wall screen being restored & put back into the house, reuse of marble fireplace mantles & surrounds, historic balcony railings & building facades that make the french quarter look so special & exterior wood stairs, etc. I realize some will say to include such items in C&D waste recycling but I feel due to the project's historic significance what we are saving should be weighted more than what we took out which was non historical & non significant. 

Any ideas? any experience from reviewers comments?

Thanks,

Debra, I'm afraid I don't have any suggestions here, other than to say you're not alone in feeling that this work is undervalued, and this contributed to the LEED v4 MRc1 credit that recognizes historical properties. Are you familiar with that credit? You should also check if this LEED 2009 credit is eligible for LEED v4 credit substitution. (Google USGBC guidance on that topic.) The other saving grace is to count these under Material Reuse, with an appropriately high monetary value assigned to them.

Thank you Tristan! We are applying for an ID credit for Historic Preservation & will follow credit language that I found under -ND for such. I'll see how that language compares to the HP credit under v4. I didn't think that reuse of materials for onsite can contribute to MRc3 (3.1, 3.2) Resource Reuse credit. I thought MRC3 was only for salvaged material being brought to site, acquired from offsite, for use on-site. Am I wrong on this? THANKS! Debra

Hi Tristan, I saw on your website the following under MRc2: https://leeduser.buildinggreen.com/forum/mr3-materials-reuse-and-mr4-recycled-content-double-dipping  "MRc3: Material Reuse can involve material that is salvaged onsite and used again onsite for another purpose or in another location. The onsite salvaged material can count towards both MRc3: Material Reuse and MRc2: Construction Waste Management. For example, if a project demolishes a building and saves all the wood doors from going to the landfill, then turns the salvaged doors into countertops for the new construction, the salvaged doors count both credits. " Do you know of anywhere in the v2009 NC reference guide or in a CIR where that is stated as our initial review states we can't count onsite salvaged material in both MRc2 and MRc3. we have numeours onsite salvage items. some are being used in the same application as original and some items are reused in a different application. so I was hoping to at least be able to count the materials reused in a different type application but I can't find any exact LEED language to quote in our certif. review reply. Thank you!! Thanks!

I'm also wondering if we have 80% bldg reuse and thus exceed the 2 point threshold by 5%, if we can count that 5% (not to be awarded for in MRc1) in credit MRc2? OR  If just because the the project "qualifies" for MRc1.1, that we can't apply the 5% material (exceeding 2 point threshold & not to be awarded in MRc1) towards credit MRc2. Thanks!
