The remaining measures referenced in ASHRAE 90.1-2022, Section 11.5.2 are ineligible for incremental LEED points, since these measures are separately rewarded in other LEED credits:

  • P01: Energy Monitoring is rewarded under EAc4: Enhanced Commissioning, Option 2. Monitoring-Based Commissioning (MBCx)

  • R01: Renewable Energy rewarded in EAc3: Renewable Energy

  • Q01: Efficient Elevator Equipment and Q02: Efficient Kitchen Equipment rewarded in EAc2: Enhanced Energy Efficiency, Option 1, Path 3. Plug and Process Loads.

  • G01 to G06 Load Management and E01: Improved Envelope Performance measures rewarded in EAc5: Grid Interactive

EQUIVALENCE TO ASHRAE 90.1 FOR OPTION 1. PRESCRIPTIVE PATH, PATHS 1 AND 2.

Refer to the Project Priorities Library for regional paths addressing equivalence to ASHRAE 90.1 .

To be eligible to apply Paths 1 or 2 of EAc2: Enhanced Energy Efficiency, Option 1. Prescriptive Path, projects using an ASHRAE 90.1 equivalent standard must use a prescriptive method from that standard: compliance must be demonstrated per category of building systems (building envelope, HVAC, lighting, SWH, etc.), without trade-offs between system categories.

Path 1. ASHRAE 90.1-2022 Compliance for Project Scope

This path is awarded to projects documented using a prescriptive method of an ASHRAE 90.1- 2022 equivalent standard.

Path 2. Regulated Loads

CASE 1. ADDITIONAL EFFICIENCY — SYSTEMS OPTIMIZATION APPLIES TO MOST PROJECTS USING AN EQUIVALENT STANDARD Prescriptive values from the ASHRAE 90.1-2019 -equivalent standard for efficiencies such as lighting power density allowance or equipment efficiency may replace ASHRAE 90.1-2022, Section 11 referenced values. Any strategies applied must be incremental to
