that the use, specification, and disposal of building materials
will minimize the effect a building has on the environment.
MRp1 - Designated accessible end-user recycling area for paper,
corrugated cardboard, glass, plastics, and metals.
MRc1 - Maintain 75% (MRc1.1), or 95% (MRc1.2) of existing building
structure and envelope. Maintain 50% of interior non-structural
elements for MRc1.3.
MRc2 - Recycle and/or salvage 50% (MRc2.1), or 75% (MRc2.2) of
non-hazardous construction and demolition waste and debris.
MRc3 - Use salvaged, refurbished, or reused materials for at least
5% (MRc3.1), or 10% (MRc3.2) of total materials, by cost.
MRc4 - Use 10% (MRc4.1) or 20% (MRc4.2) of total materials, by
value, with recycled content (recycled content = post-consumer + ½
MRc5 - Use 10% (MRc5.1) or 20% (MRc5.2) of total materials by
value that have been extracted, harvested or recovered, as well as
manufactured, within 500 miles of the project site.
MRc6 - Use rapidly renewable building materials for 2.5% of the
total materials by value.
MRc7 - Use Forest Stewardship Council (FSC) certified wood
materials and products for 50% of all wood-based materials and
products used in the project.
- Tie contractor retainage to complete submission of LEED
product/material submittals and document everything.
- Education of subcontractors on recycling practices and
established penalties (such as fees) for not following these
practices help achieve the highest percentage of construction waste
diverted from the landfill.
- Incentives, given by the general contractor or owner, to
subcontractors for meeting targeted MR goals can both motivate and
benefit all involved.
- Renovation and/or expansion projects are most applicable to
- Help contractors develop a waste management plan early to
ensure best practices from the initial phases of the project.
- Identify local waste recycling /salvaging resources before
- Target high-dollar items early in the project to include
recycled content or local manufacturer/harvesting in the
- Ensure application of renewable materials is appropriate.
- Confirm lead time for any and all FSC materials.
