Usage Guidance

This metric is intended to capture the area of reused buildings that will be renovated or remodeled as a result of investments made by the organization during the reporting period. In order to qualify for reuse, the time elapsed since the completion of original construction must meet or exceed 40 years.
-
Buildings are often renovated or remodeled for reuse to conserve resources, extend the life of existing building stock, retain cultural resources, reduce waste, and avoid the additional environmental impacts of new construction.
