SDG&E will submit the Program Manual following the contracting of the Implementer who will administer the HOPPs RCx program. The Program Manual will also include specific information for MBCx projects. The goal of the RCx program is to implement ECMs that: Address problems with existing controls; Enhance control and operation of existing equipment; and Make repairs/upgrades to existing equipment such that it operates more efficiently. 1. Eligible Measures The most common system and equipment enhancements for RCx projects include: air handlers, chillers, cooling towers, economizers, boilers, lighting and controls. Eligible measures will be determined on a project-by-project basis. The following list includes some of the most common RCx measures that will be considered: Scheduling Equipment Loads: Occupied/Unoccupied Temperature Time of Day Setpoints Controls: Reset Schedules: Optimum Start-Stop HW Supply Temperature Reset or HW Lighting Controls Economizer/Outside Air Loads: Plant Scheduling CHW Supply Temperature Reset Inadequate Free Cooling CW Supply Reset for Chiller Efficiency Over-Ventilation Optimization (for Newer VFD Chillers) Demand Controlled Ventilation Supply Air Temperature Reset: Cooling Control Problems: and Heating Simultaneous Heating and Cooling Duct Static Pressure Sensor/Thermostat Calibration and/or Equipment Efficiency Improvements / Load Optimal Relocation Reduction: Hunting and Loop Tuning De-Lamping of Over-Lit Spaces Actuator Calibration Pump Discharge Throttled, Zone Rebalancing and Low Delta T–Trim Impeller Controls: Setpoint Changes: Variable Frequency Drives (VFDs) Fans and Duct Static Pressure Setpoint Pumps Piping Differential Pressure Setpoint Equipment Maintenance: Reduction of VAV Box Minimum Leaking Valves (hot water or chilled Setpoint water valves) Implementation/Adjustment of Actuator / Damper Operation Heating/Cooling, and
