Example 1 A new construction two-story retail project in climate zone 4A earns five LEED points: four points for complying with ASHRAE 90.1-2022 using the prescriptive method and one additional point for achieving at least 25 incremental energy credits above the minimum required from the list of eligible measures.
Per ASHRAE 90.1-2022, Table 11.5.3-6, the project must achieve at least 50 energy credits to comply with ASHRAE 90.1-2022 using the prescriptive method.
ECreq = 50
-
The project documents achievement of 97 total energy credits per ASHRAE 90.1-2022, Section 11.
-
H02: HVAC Heating Performance Improvement . 20% or greater weighted average improvement in ASHRAE 90.1-2022 heating efficiency achieves 28 energy credits.
-
L04: Increased Daylighting Control Area. 65% of total daylighting area with continuous daylight dimming achieves four energy credits.
-
L06: Reduce Interior Lighting Power . 10% or greater improvement in ASHRAE 90.1- 2022 regulated lighting power achieves 20 energy credits.
-
E01: Improved Envelope Performance. 4.5% improvement in envelope performance factor achieves 45 energy credits.
ECtotal = EC_H02 + EC_L04 + EC_L06 + EC_E01 ECtotal = 28 + 4 + 20 + 45 = 97
- 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 47 incremental energy credits above the minimum required for prescriptive method compliance.
ECinc = Minimum (ECeligible, ECtotal − ECreq) ECinc = Minimum (52, 97 − 50) = 47
