• Provide shade from structures covered by solar panels that produce energy used to offset some nonrenewable resource use.
• Provide shade from architectural devices or structures that have a solar reflectance index (SRI)² of at least 29.
• Use hardscape materials with an SRI of at least 29.
• Use an open-grid pavement system (at least 50% pervious).

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.
