Requirements
Use on-site renewable energy systems to offset building energy costs. Calculate project performance by expressing the energy produced by the renewable systems as a percentage of the building’s annual energy cost and use the table below to determine the number of points achieved. Use the building annual energy cost calculated in EA Credit 1: Optimize Energy Performance or the U.S. Department of Energy’s Commercial Buildings Energy Consumption Survey database to determine the estimated electricity use.The minimum renewable energy percentage for each point threshold is as follows:

We have a PV array installed on our campus, under the same ownership, but not on the building or within the LEED project boundary. Can we count that toward EAc2?The answer to this question is available to LEEDuser premium members. Start a free trial » (If you're already a premium member, log in here.) |
Because of how our onsite PV system was financed through the utility, the project is selling the RECs associated with its solar energy production, even though we own the PV array and its power.

Can I pursue this credit if I am using one of the prescriptive compliance paths for EAp2/EAc1?The answer to this question is available to LEEDuser premium members. Start a free trial » (If you're already a premium member, log in here.) |
Can I really double-count onsite renewable energy in both EAc2 and EAc1?The answer to this question is available to LEEDuser premium members. Start a free trial » (If you're already a premium member, log in here.) |
Our PV system is being installed after the building is occupied. Is that okay?The answer to this question is available to LEEDuser premium members. Start a free trial » (If you're already a premium member, log in here.) |
Our project will have a PV system onsite, but it will be installed, operated, and owned by a separate entity that is paying for the system through a premium price per kWh paid by the utility, per state regulations.

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.
