No. Hazardous waste does not count and it is excluded from the numerator and denominator portions of the credit calculations. You may want to include a brief narrative on the hazardous waste you found and how your project abated the material.
Yes, materials that would otherwise be waste, but that are diverted from the landfill to be salvaged or reused can contribute to MRc2.
LEED Interpretation #10265 made on 01/01/2013 provides the best official guidance for this situation. The approach that is approved in that situation involves multiple buildings, all being certified to LEED-NC. The ruling allows the project to track together all demolition and construction waste diverted, and to then apply a weighted average based on gross square footage to each LEED project.
Waste generated off-site, even for modular construction and pre-fabrication of major assemblies is not accounted for in the MRc2 calculations. MRc2 looks only at the management of waste generated onsite.
Yes. However, if occupants have access, there should be no parking subsidies provided that would encourage tenants to use the parking (as required by credit language).
Since parking availability for CI projects may not correlate with building size or square footage as in the case in NC, this change helps level requirements across CI projects.
No. According to the LEED glossary, these materials are considered remanufactured, and therefore do not qualify as reuse. Under the Related Credits section in the LEED Reference Guide, it states that “Remanufactured materials are not considered a reuse of the material and do not contribute toward this credit. However, these materials can contribute toward MR Credit 2: Construction Waste Management, or MR Credit 4: Recycled Content."
Probably not. LEED Interpretation #2501 made on 03/20/2009 emphasizes previous use of building materials as a key consideration for this credit, with reference to structural steel.
No, as the material is being "re-manufactured' into something else, it is different than reuse, where products and materials are used intact, but in different applications or locations. The primary environmental attributes for this case are construction waste management (MRc2), and potentially recycled content (MRc4), and regionality (MRc5). The intent of this credit is to extend the life of existing building materials.
No. Consistent with other MR credits, MEP equipment should not be counted here.
