CI-v5 MRc1: Interior Materials Reuse 1-4 points

Intent

To discourage unnecessary demolition and encourage the on-site reuse of existing interior elements and furniture, and to incorporate reused materials into new project design wherever possible. Such practices reduce embodied carbon, keep materials in circularity, reduce demand for virgin material sourcing, preserve cultural resources and histories, and foster markets for reused materials. 

Requirements

Demonstrate reduced environmental impacts during initial project decision-making by reusing existing building resources and by incorporating off-site reused materials into the project design. For projects with deconstruction or demolition in scope, conduct a salvage assessment prior to deconstruction or demolition activities and identify materials that can be retained on-site or diverted off-site to reuse markets.

NOTE: Materials sent for off-site reuse contribute to waste diversion in MRc5: Construction and Demolition Waste Diversion. Materials retained on-site or acquired from off-site sources and incorporated into the project contribute to this credit.

Achieve points through building and/or material reuse. Pursue Option 1 and/or Option 2 for a maximum of 4 points.

Option 1. Reuse Existing Interior and Minimize Renovation (1–4 points)
Maintain the existing interior nonstructural elements and furniture. Only materials that remain in place (on-site reuse) are included in this credit option. On-site reuse can include materials that come from the same project owner’s stockpile or warehouse but excludes any off-site reused materials incorporated into the project that originate from external sources. Hazardous materials remediated as a part of the project must be excluded from the calculation.

PATH 1. FURNITURE AND INTERIOR NONSTRUCTURAL ELEMENTS REUSE (1–4 POINTS)
Compile the total cost for the project’s on-site reused and new nonstructural elements and furniture, pricing reused elements as if they were new. Include all the following elements in the project, as applicable to the scope of work: flooring, walls, ceilings, insulation, and furniture.  Determine the cost of the elements of the project that are reused on-site and calculate the percentage of the total value of the project, including both new and reused. Points are awarded according to Table 1.

OR

PATH 2. FURNITURE REUSE (1–2 POINTS)
Compile the total cost for the project’s furniture that is reused on-site. Include the total project cost for reused and new furniture, pricing the reused furniture as if it were new. Determine the percentage of reused furniture based on cost and earn points according to Table 2.

AND/OR

Option 2. Material Reuse (1–3 points)
Survey and identify material procurement opportunities from off-site reuse and/or salvage sources. Incorporate reused materials into the project design. Specific targeted reuse materials are valued higher because they have high impacts (embodied carbon or pollution) and are hard to recycle, and because significant amounts of these materials end up in landfill.

Earn points according to Tables 3 and 4. Calculate the percentage reused per material type according to Equation 1.

Equation 1. Reuse % per material type

Reuse % per material type = Amount of material type reused / Total amount of material type in commercial interiors scope
