This incentive is available for the upgrade of single-zone constant volume rooftop units by integrating a control system that combines an advanced digital economizer controller, a supply fan VFD and a demand-controlled ventilation system.

Required Documentation:
- Proof of Existing System: Documentation or verification showing the current setup as a single-zone constant volume system without VFD, DCV or economizer controls. As well as, the capacity of the rooftop heating system, usually in BTU/hr.
- Implementation Details: Detailed specifications and installation records for the new control system, including economizer controls, DCV mechanism and supply fan VFD.
- Applicability: Eligible for upgrades of existing single-zone constant volume systems that currently lack VFDs, demand control ventilation and economizer controls and new construction projects.
- Baseline Efficiency: The baseline system assumes a non-functioning economizer, outdoor air set at the code value for maximum occupancy and a constant speed supply fan.
- Qualifying Efficiency Requirement:
- The new advanced system must include the installation of functional economizer controls.
- Also, a DCV control mechanism, typically employing CO2 sensors, must be installed to adjust the volume of ventilated air based on real-time occupancy levels.
- Furthermore, a VFD must be added to the supply fan, allowing for speed adjustments during periods of reduced demand.
- Exclusions:
- Cannot be combined with separate measures for DCV, conversion from CAV to VAV on AHU, VFD on HVAC fans or standalone air-side economizer projects.
