Option 1. Building Reuse

Building reuse extends the lifespan of structures by revitalizing existing buildings or adapting properties when their original function changes. Demolishing an old building and rebuilding with new materials increases a building’s carbon footprint due to the energy required for both processes. Reusing a building conserves resources by reducing the need for new construction materials and minimizes waste. This option can be more cost-effective, reducing the environmental impact associated with construction.

Option 1 addresses the onsite reuse of existing structure and enclosure materials, including materials left in-situ as well as those procured offsite and incorporated into the building’s structure/enclosure. To earn points, projects maintain portions of the existing building structure and enclosure and/or incorporate offsite reuse from the early design phase and work with architects and structural engineers to identify structural elements of the existing space that can be reused.

Table 5 outlines how different types of reuse are recognized within the LEED v5 Materials and Resources category, including their contributions to MRc5: Construction and Demolition Waste Diversion and MRc4: Building Product Selection and Procurement .
