Extracted Content

• Dedicated physical space for future electric space heating, service water heating, or process heating equipment. Provide designated spaces of sufficient size for outdoor heat pump equipment.

  • Chase ways with space for refrigerant lines, condensate drainage, or other required piping.

  • When electrical distribution systems are installed within the project scope, provide a junction box in the same physical space as the space allocated for the future electric equipment, and dedicated electrical panel space for an appropriately phased branch circuit sized to accommodate the future electric equipment or appliances to meet the specified load.

  • For portions of the building where ventilation air is not installed within the project scope of work, provide space and accommodations capable of supporting energy recovery ventilation for at least 50% of ventilation air.

For all options

Equipment Efficiency

Determine weighted average COP using either of the following:

• Equipment efficiencies at rated conditions :

o 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.

o 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 refer to outside air dry-bulb temperatures (OA db) below 20°F (–6.5°C).
