Demand Controlled Ventilation and Energy Savings

  1. 1. DDemandCControlledVVentilation for Energy Savings
  2. 2. Conventional VentilationVentilation is typically based on:• Maximum occupancy (worst-case scenario)• Constant intake of fresh air (even if unoccupied) Image: sixninepixels / FreeDigitalPhotos.net
  3. 3. The Result• Significant waste of energy and money• Excess running of fans• Excess heating of cold intake air• Excess cooling of warm intake air
  4. 4. Demand-Controlled Ventilation (DCV)Outside Air Adjust fresh-air 90% Occupied intake based on Floor 4 occupancy 10% Occupied Floor 3 Ventilation demand 50% Occupied Floor 2 is determined by CO2 level (ppm) 80% Occupied Floor 1
  5. 5. DCV Benefits• Maintain acceptable indoor air quality (IAQ)• Reduce energy consumption• Monitor space occupancy• Meet ASHRAE standards• Support LEED certification
  6. 6. Powercast Wireless CO2 Sensors • Fast installation / Easy relocation • Reduced occupant disruption • Long battery life (3-15 years) • 0 - 5000ppm measurement • Connect to any BAS network
  7. 7. Powercast Sensor System Building Wireless CO2 Network Sensors Local Monitoring Wireless Gateway CloudMonitoring
  8. 8. PaybackPayback = System CostPeriod Monthly Energy Savings• Measured in months, not years• Timeframe supported by US DoE studies
  9. 9. Where to Use?• Office buildings• Theaters, Auditoriums• Shopping malls, retail complex• Hospitals, Hotels, Schools, Dormitories• Government buildings• Bars, nightclubs, entertainment venues• Many other places of human occupancy
