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.

Revise the below SS credit intents as follows:
SSp Construction Activity Pollution Prevention
"To reduce pollution from construction activities by controlling soil erosion, waterway sedimentation, and airborne dust that disproportionately impact frontline communities."
SSc Site Assessment
"To assess site conditions, environmental justice concerns, and cultural and social factors, before design to evaluate sustainable options and inform related decisions about site design."
SSc Rainwater Management
"To reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site, based on historical conditions and undeveloped ecosystems in the region to avoid contributing to flooding downstream in frontline communities."
SSc Heat Island Reduction
"To minimize inequitable effects on microclimates and human, especially frontline communities, and wildlife habitats by reducing heat islands."
SSc Places of Respite
"To provide patients, all staff, and visitors with the health benefits of the natural environment by creating outdoor places of respite on the healthcare campus."
SSc Direct Exterior Access
"To provide patients, all staff, and visitors with the health benefits of the natural environment by creating outdoor places of respite on the healthcare campus."

Description of change:
For BD+C, revise language under Table 1 to read as follows. For O+M insert the language below under Table 1.
"Roof area that consists of functional, usable spaces (such as helipads, recreation courts, and similar amenity areas) may meet the requirements of nonroof measures. Applicable roof area excludes roof area covered by mechanical equipment, solar energy panels, skylights, and any other appurtenances."

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.
