Building Reuse: Maintain 75% of Existing Walls, Floors and Roof

LEED 2.2 Requirements:

Maintain at least 75% (based on surface area) of existing building structure (including structural floor and roof decking) and envelope (exterior skin and framing, excluding window assemblies and non-structural roofing material). Hazardous materials that are remediated as a part of the project scope shall be excluded from the calculation of the percentage maintained. If the project includes an addition to an existing building, this credit is not applicable if the square footage of the addition is more than 2 times the square footage of the existing building.

Submittals (DESIGN):

- Provide the existing building area (sq. ft.).
- Confirm whether the project is strictly a renovation of an existing building or a renovation with an addition. For projects with additions, confirm the square footage of the new addition(s).
- Provide a tabulation of the existing and reused areas (sq. ft.) of each structural/envelope element. AND (For Projects With Special Circumstances)
- Provide an optional narrative to describe any additional comments or notes regarding special circumstances or considerations regarding the project's credit approach.
