Extracted Content

  • Equipment efficiencies at rated conditions. For equipment with multiple rated conditions, use the rating closest to 17°F (-9°C) OA db, 32°F (0°C) entering liquid temperature, or 44°F (6°C) heating source leaving liquid temperature.

    • Annual average COP calculated with an energy simulation.

District energy Projects with district energy must comply with the requirements of this credit at the district facility or see additional guidance for interpretation of credit requirements.

Fuel cells Fuel cells using fossil fuel are ineligible for credit.

Low temperatures “Low temperatures” refers to outside air dry-bulb temperatures (OA db) below 20°F (-6.5°C).

REQUIREMENTS EXPLAINED

This credit rewards decarbonization achieved through electrification of building systems traditionally fueled with on-site combustion, including space heating, SWH, cooking, and other process equipment.

Projects may choose between Options 1–4. For all options, electrified space heating and SWH equipment must meet efficiency criteria to limit undue burden on the electric power grid. Refer to the Weighted Average COP section for further guidance.

The requirements for Options 1, 2, and 4 encompass base building systems serving the project and systems within the project scope. These options are most appropriate for projects with the majority of HVAC and SWH capacity in the project scope of work or projects that intentionally locate in electrified or partially electrified buildings.

  • Maximum points are available under Option 1 to projects that fully electrify all base building and project systems.

  • Option 2 selectively rewards electrification per system category for heating, SWH, and cooking and other process loads; and affords flexibility for a hybrid design capable of limiting on-site combustion to low-temperature operation.

  • For projects located in buildings certified under LEED v5 (either LEED BD+C or LEED AP O+M), Option 4 provides a streamlined documentation method for demonstrating project performance. Requirements for Option 4 are similar to those in Options 1 and 2; however, for existing buildings using Option 4, the efficiency requirements only apply to elements within the project scope.
