- SWH equipment in nonresidential spaces complying with the point-of-use water heater criteria in ASHRAE 90.1-2022, Section 11.5.2.3.3, W05, without exceptions
OR
Option 2. No On-Site Combustion Except at Low Temperatures—Base Building and Tenant Systems (1–5 points)
Pursue any combination of the following paths for a maximum of 4 points:
PATH 1. SPACE HEATING (2 POINTS)
Design space heating to be capable of operating without on-site combustion except at low temperatures. Projects in climate zones 3 and above must have a weighted average space heating equipment efficiency of at least 1.8 COP for initial build-out construction or at least 1.2 COP for alterations.
The following equipment may be excluded from the COP determination:
- Supplemental heating equipment designed only for operation at low temperatures
AND/OR
PATH 2. SWH (1 POINT)
Design SWH systems to be capable of operating without on-site combustion except at low temperatures. Projects with total SWH capacity exceeding 34,000 Btu/hr (10 kW) must have a weighted average service hot water equipment efficiency of at least 1.8 COP for initial build-out construction or at least 1.2 COP for alterations.
The following equipment may be excluded from the COP determination:
-
SWH equipment in nonresidential spaces complying with the point-of-use water heater criteria in ASHRAE 90.1-2022, Section 11.5.2.3.3, W05, without exceptions
-
Supplemental heating equipment designed only for operation at low temperatures
AND/OR
PATH 3. COOKING AND OTHER PROCESS LOADS (1–2 POINTS)
Design cooking, laundry, process equipment, and on-site power generation except emergency support systems to be capable of operating without on-site combustion.
Not in scope (1 point)
- Cooking, laundry, or process heating systems are not in project scope of work.
