powering of vehicles or equipment operated exclusively on the project site (e.g., forklifts or golf carts).

All process systems serving the project must be capable of operating without on-site combustion, except in low-temperature operating mode for outdoor dry-bulb temperatures at or below 20°F (-6.5 °C). This requirement extends to any process heating or on-site electricity generation supplied from the base building systems to the project.

Exception Clothes washers supplied with SWH from the base building systems are not required to show compliance for the hot water connection.

Not in scope One point is rewarded to projects that do not have cooking, laundry, and/or process heating systems in the project scope of work, provided that any existing cooking or other process equipment reused in the project, and any process heating or on-site electricity systems serving the project, meet the criteria above.

In scope A second point is available under this path for projects that electrify process systems within the scope of work, since this contributes more heavily to overall decarbonization achieved for the project. One of the following must be in scope:

  • Cooking . Cooktops, ovens, fryers, griddles, or any other commercial or residential cooking equipment traditionally fueled by natural gas or other fossil fuels

  • Laundry . Clothes dryers or clothes washers with hot water supply free of on-site combustion

  • Process heating equipment . Industrial boilers or furnaces

  • Drying equipment used for industrial processes

  • On-site power generation such as solar PV

Other cooking or process equipment that can only be powered by electricity such as microwaves cannot be used to achieve the 2nd point.

Option 3. No On-site Combustion, Limited Scope

This option is intended for projects with limited scope that do not install systems using on-site combustion. Combined weighted average equipment efficiency for space heating and SWH systems installed in the project scope of work must be at least 1.8 COP for initial buildout or at least 1.2 COP for projects in existing buildings. Refer to the guidance in the Weighted Average COP section.
