  1. Eugene Water & Electric Board Premium Ventilation

  2. Review Recommendations for Premium Western Economizer • Primary sensor control location • Two-stage thermostat & coordination • Differential dry-bulb outside air changeover • Adequate air flow and exhaust relief • Ventilation control • Quality Assurance Premium Ventilation

  3. Desired Sequence • Min OSA ventilation during heating • Use ventilation before cooling • Use full OSA vent with cooling coil • Lock out or Change over from ventilation to minimum when OSA too warm Premium Ventilation

  4. Premium Ventilation • Start with a Western Premium Economizer • Upgrade the Economizer module with • DCV capable economizer control module • CO2 Sensor; Min air set to 0% = leakage • Add variable speed fan motor • Full (or near full) speed in heating or cooling • Low (30%) speed in idle mode Premium Ventilation

  5. Triple the Savings • Premium Economizer Savings, plus • Fan savings when not heating or cooling • Savings during warm-up by reducing ventilation when not occupied • Ventilation heating and cooling savings when building not fully occupied • No need to set and measure outside air minimum Premium Ventilation

  6. Regional Savings Premium Ventilation

  7. New Units or Retrofit • Retrofit VSD Options • ICM CC750 • Fan Handler • Both use temperature control strategy Premium Ventilation

  8. Currently Custom Incentives • Move towards rebate approach • Two contractors have proposals for work • New Construction and Replacement market Premium Ventilation
