REQUIREMENTS EXPLAINED

This credit encourages projects to reuse existing buildings and building materials. Option 1 rewards projects that reuse structural and enclosure elements of existing buildings. Option 2 is focused on the reuse of nonstructural products by keeping materials in place or acquiring materials from salvaged sources. This option encourages projects to focus on reusing targeted materials that have high environmental impacts. Points are earned based on the percentage of targeted and other materials that are reused in the project.

Reusing materials in new building designs benefit the environment by lowering the demand for virgin material sourcing, decreasing embodied carbon, and extending the lifecycle of products. Materials diverted through construction activities and sent offsite for reuse contribute to the MRc5: Construction and Demolition Waste Diversion .
