Example A dedicated outside air system with 3.0 COP heat pump supplies 15% of total combined heating and service water heating required for the project, achieving a weighted average COP of 1.3. No other systems are in scope.

PATH 2. NO ON-SITE COMBUSTION EXCEPT AT LOW TEMPERATURES

Case 1. Space Heating

Refer to New Construction Option 2, Path 1 above. For a Core and Shell project scope that addresses only a portion of space heating loads, the 1.3 COP weighted average COP threshold worth one point is more attainable than the 1.8 COP threshold worth two points.

Case 2. Service Water Heating

Refer to New Construction Option 2, Path 2 above.

PATH 3. NO ON-SITE COMBUSTION — LIMITED SCOPE

This path applies to projects that have inadequate scope to achieve points under Path 1 or Path 2.

Projects must fully electrify any space heating or service water heating systems in scope and achieve a combined weighted average equipment efficiency of at least 1.8 COP for these systems per the guidance in the Weighted Average COP section below.

Minimum scope must include at least one space heating, service water heating, or process heating system for one point; and at least 30% of the project’s combined heating and service water heating load for two points.

Option 2. Electrification Readiness

Electrification of building heating systems directly reduces carbon emissions in buildings. For Core and Shell projects, the exact project scope may vary, and project teams may only provide the infrastructure without selecting and installing all heating generation equipment. Under this circumstance, demonstrate that the provided building infrastructure supports future equipment that does not rely on combustion for space heating, service water heating, and process heating. Refer to the rating system language for specific electrification-readiness strategies that must be included in the project design if applicable to the project application.

Provide tenant guidelines that explain the electrification readiness strategies and address the design and installation of efficient electrified systems.
