Requirements
Maintain the existing building structure (including structural floor and roof decking) and envelope (the exterior skin and framing, excluding window assemblies and nonstructural roofing material). Hazardous materials that are remediated as a part of the project must be excluded from the calculation of the percentage maintained. The minimum percentage building reuse for each point threshold is as follows:
Building Reuse |
Points |
|---|---|
25% |
1 |
33% |
2 |
42% |
3 |
50% |
4 |
75% |
5 |
What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
