The project achieves 27 incremental energy credits above the minimum required for prescriptive method compliance, which exceeds the 25 required for two LEED points.
ECinc = Minimum (ECeligible, ECtotal − ECreq)
ECinc = Minimum (52, 52 − 25) = 27 Example 2. Substantial alteration retail project in climate zone 4A Renewable energy used to earn energy credits for prerequisite compliance.
The project referenced in Example 1 adds a roof-mounted PV array with a rated capacity of at least 0.75 W/sq. feet (8.1 W/sq. m.) of the project’s gross floor area, achieving 15 energy credits for measure R01: On-site Renewable Energy, and maximizing the combined allowable ASHRAE 90.1-2022, Section 11 contribution for renewable and load management credits. The project achieves 67 total energy credits per ASHRAE 90.1-2022, Section 11.
ECtotal = EC_H02 + EC_L04 + EC_L06 + EC_R01
ECtotal = 28 + 4 + 20 + 15 = 67 Of these energy credits, 52 are from measures eligible for LEED points (H02, L04, and L06). Therefore, the project achieves 42 incremental energy credits above the minimum required for prescriptive method compliance, which exceeds the 38 required for three LEED points.
ECinc = Minimum ( ECeligible, ECtotal - ECreq )
ECeligible = Minimum ( 52, 67 - 25 ) = 42
