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.

LEED Interpretation
Inquiry:

Can v4 projects use typical solar reflectance (SR) values, or data from a previous project, for documentation of hardscape materials?

Ruling:

The following typical SR values can be used for standard nonroof materials, in lieu of project-specific testing data:

Typical Solar Reflectance Values for Standard Nonroof Materials
Gray cement concrete- Initial Solar Reflectance: 0.26, Three-Year Aged Solar Reflectance*: 0.18
White cement concrete- Initial Solar Reflectance: 0.70, Three-Year Aged Solar Reflectance*: 0.35
Asphalt concrete- Initial Solar Reflectance: 0.05, Three-Year Aged Solar Reflectance*: 0.10

*Three-year aged SR values are based on no cleaning.

Alternatively, documentation showing that the current concrete mix and sealant are equivalent to a tested mix and sealant from a previous project is acceptable, provided that all ingredients are the same and have not changed.

Campus Applicable
Yes
Internationally Applicable:
