LEED v5 BD+C Rating System_November 2025_clean - Page 095
Extracted Content
Equipment efficiency : Determine weighted average COP using either of the following:
-
Equipment efficiencies at rated conditions : For equipment with multiple rated conditions, use the rating closest to 17°F (−9°C) outside air dry-bulb temperatures (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 : The term Low temperatures refers to OA db below 20°F (−6.5°C).
REQUIREMENTS: CORE AND SHELL
| Achievement Pathways | Points |
|---|---|
Core and Shell | 1–4 |
Option 1. Electrification | 2–4 |
Path 1. No On-Site Combustion | 3–4 |
OR | |
Path 2. No On-Site Combustion Except at Low Temperatures | 1–3 |
Case 1. Space Heating | 1–2 |
AND/OR | |
Case 2. Service Water Heating | 1 |
OR | |
Path 3. No On-Site Combustion—Limited Scope | 1–2 |
AND/OR | |
Option 2. Electrification Readiness | 1 |
Option 1. Electrification (2–4 points)
For Paths 1 and 2:
- Include all heating and service hot water systems necessary to meet total building
heating and SWH load in the calculations of weighted average COP.
- Future heating or SWH systems must be included in the calculations with a COP of
1.0.
- Future equipment may be excluded from the calculations and deemed as compliant
when the applicable building code, or construction drawings for projects with tenancy, confirms a weighted average COP of at least 1.8 for future installed equipment.
