Area of buildings projected to be renovated/remodeled that qualify for building reuse as a result of investments made by the organization during the reporting period.
Organizations should footnote details on why the renovated/remodeled building areas qualify for reuse.
Buildings are often renovated/remodeled for reuse in order to conserve resources, extend the life of existing building stock, retain cultural resources, reduce waste, and reduce environmental impacts of new buildings.
In order to qualify for reuse, the time elapsed since the completion of original construction must meet or exceed 40 years.
