Schools 2009 MRc1.2: Building Reuse—Maintain Existing Interior Nonstructural Elements

  • MRc1.2 NC schools diagram

  • Refinish and reuse existing elements

    You may find on a renovation of an existing building that some interior elements, such as walls, ceilings and doors, are in perfectly good condition and do not need to be replaced. This credit awards you one point for refinishing and reusing 50% of these elements. Projects are only eligible for this credit if the gross built area of the final building is less than two times the existing built area.

    Check the calculation details

    The calculation for this credit is a function of the total interior elements present upon construction completion, including both the existing and the new non-structural building components used in the project. Note that this approach contrasts with the calculation method in MRc1.1: Building Reuse—Structure and Shell, where...

Non-structural wall resurfacing

Our project has existing non-structural plaster walls that will be reused in place. The current design calls for touch up of existing plaster walls, but the owner is also contemplating full skip-trowel resurfacing or overlayment of new gyp board. I am trying to ascertain what the impacts of these 3 scenarios would be on credits MRc1.2 and MRc3.

Secondly, acoustical panels may be necessary in some rooms to meet the LEED for schools pre-req, so we have a similar question regarding impacts to MRc1.2 and MRc3.

Thanks in advance to anyone who can help.

James, if you can touch up the walls only, then they contribute to MRc1.2. If they are resurfaced, that's a bit of a gray area and would depend on your and your LEED reviewer's judgement of whether the situation falls more under reuse and restoration vs. replacement. Overlaying them with gypsum board would definitely disqualify that surface for MRc1.2, but not pulling it out could potentially benefit you under MRc2.

Covering the existing ceiling with acoustical panels would disqualify it for MRc1.2

There are no MRc3 implications here that I can see—none of these materials are eligible for that credit.

I hope this helps.
