Option 2. Materials Reuse (1–2 points)

Survey and identify opportunities for materials reuse and/or procurement of reused materials from off-site.
Reuse materials by keeping them in place or acquiring them from applicable salvage sources or reuse markets and incorporating the materials into the new project design. Specific targeted materials are valued higher because they have high impacts (embodied carbon or pollution) are hard to recycle and significant amounts of these materials end up in landfill.
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.

o Salvaged materials sent for off-site reuse contribute to MRc5: Construction and

Demolition Waste Diversion. Materials retained on-site contribute to this credit option.

Calculate the percent reused per material type according to Equation 1.

Points are achieved according to Table 3.

Equation 1. Reuse % per material type

𝑅𝑒𝑢𝑠𝑒 % 𝑝𝑒𝑟 𝑚𝑎𝑡𝑒𝑟𝑖𝑎𝑙 𝑡𝑦𝑝𝑒 = 𝐴𝑚𝑜𝑢𝑛𝑡 𝑜𝑓 𝑚𝑎𝑡𝑒𝑟𝑖𝑎𝑙 𝑡𝑦𝑝𝑒 𝑟𝑒𝑢𝑠𝑒𝑑 / 𝑇𝑜𝑡𝑎𝑙 𝑎𝑚𝑜𝑢𝑛𝑡 𝑜𝑓 𝑚𝑎𝑡𝑒𝑟𝑖𝑎𝑙 𝑡𝑦𝑝𝑒 𝑖𝑛 𝑁𝑒𝑤 𝐶𝑜𝑛𝑠𝑡𝑟𝑢𝑐𝑡𝑖𝑜𝑛 𝑠𝑐𝑜𝑝𝑒

Table 3. Points for incorporating reused materials

Reuse materials threshold	Points
Reuse at least 15% of 1 targeted material type OR Reuse at least 15% of 2 other material types OR Reuse an equivalent weighted average of targeted and other material types	1 point
