CHILLERS
General Requirements: Chillers purchased or installed for backup or redundant systems are not eligible. Chiller components, such as motors and variable frequency drives (VFD), are incented as part of the chiller package and are not independently eligible for prescriptive incentives during a chiller replacement. AIR-COOLED CHILLERS Requirements: • Complete Table D of the “2024 HVAC and Plumbing Incentive Supplemental Data Sheet” for this measure. • For “Annual Hours of Chiller Operation,” enter total hours per year when chiller is enabled by control system to provide cooling for all or a portion of the building. • For the “Max Full Load” and “Max Part Load (IPLV)” columns, use the values listed in the Measure Description below. • For the “Delta Efficiency” column, use: (“Max Full Load”– “AHRI Rated Full Load Efficiency”) + (“Max Part Load (IPLV)” – “AHRI Rated Part Load Efficiency”). • The “Additional Incentive” is the “Delta Efficiency” x $125.00/ton for existing buildings. The incentive increases as the full and part load kW/ton exceed the minimum requirements. • The “Base Incentive” is $8.00/ton for existing buildings. • The “Incentive Rate” is: “Base Incentive” + “Additional Incentive.” • The “Total Incentive” is: “AHRI Rated Capacity” x "Incentive Rate." • Chillers must be air cooled and driven by an electric motor. Absorption chillers, engine-driven, and steam turbine-driven chillers are not eligible for this incentive but may be eligible for a custom incentive. • Manufacturer specification sheets for items installed must be submitted with the completed Incentive Application. Chiller specification sheets must include performance data, including full load efficiency in kW/ton, IPLV value in kW/ton, and capacity in tons at AHRI standard rating conditions per AHRI Standard 550/590 test procedures. • “Path A” refers to chillers that are optimized for full load applications, while “Path B” refers to chillers that are optimized for part load applications. • Incentives are calculated based on performance data (including capacity) at AHRI standard rating conditions. • The full product identification/model number must be shown on the AHRI specification sheets and invoices. • Equipment must meet both full load efficiency and part load efficiency. • Equipment must be purchased and operating prior to submitting an Incentive Application form (unless submitting for pre-approval). • Electric chiller incentives are only available for HVAC space cooling applications. • Provide all kW/ton values to three decimal places and round appropriately (e.g., enter 1.1421 kW/ton as 1.142 kW/ton). • Look for the Cooling Eligibility Screening Tool at focusonenergy.com/catalogs for assistance with determining equipment eligibility and incentive rate.
