Example 2. The project referenced in Example 1 adds a roof-mounted photovoltaic array with a rated capacity of at least 0.75 W/sq. ft. (8.1 W/sq. m.) of the project’s gross floor area, achieving 30 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. This results in achievement of six total LEED points for Path 1: four points for complying with ASHRAE 90.1-2022 using the prescriptive method, and two additional points for achieving at least 50 incremental energy credits above the minimum required from the list of eligible measures.

• ECreq = 50

• The project documents achievement of 127 total energy credits per ASHRAE 90.1-2022, Section 11.

ECtotal = EC_H02 + EC_L04 + EC_L06 + EC_E01 + EC_R01 ECtotal = 28 + 4 + 20 + 45 + 30 = 127

• 52 of these energy credits are from measures eligible for LEED points (H02, L04, and L06).

ECeligible = EC_H02 + EC_L04 + EC_L06 ECeligible = 28 + 4 + 20 = 52

• The project achieves 52 incremental energy credits above the minimum required for prescriptive method compliance.

ECinc = Minimum (ECeligible, ECtotal − ECreq) ECeligible = Minimum (52, 127 − 50) = 52
