  1. 2010 MOTION SENSOR FORUM SYSTEM INTEGRATIONGerry Cornwell, LC

  2. Overview • Technical Issues • TAF LightSavers Pilot • Matrix Gerry Cornwell Lighting

  3. Technical Issues • Technical Issues • Lamp issues • Ballast issues • Wiring issues Gerry Cornwell Lighting

  4. Technical Issues • Lamp Issues • Incandescent • Short life (2,000 hrs) • Low efficacy (15 LPW) • Instant ‘on’ • Not affected by frequent switching • Lowest first cost upgrade to CFL • Savings 60-75% Gerry Cornwell Lighting

  5. Technical Issues • Lamp Issues • CFL (Compact Fluorescent) • Longer life (6,000-10,000 hrs) • Higher efficacy (60 LPW) • OK for frequent switching • Somewhat affected by cold temperatures • Requires appropriate fixture Gerry Cornwell Lighting

  6. Technical Issues • Lamp Issues • Linear Fluorescent • Long life (+20,000 hrs) • Higher efficacy (+90 LPW) • Can be affected by frequent switching • Depends on lamp wattage • Very affected by cold temperatures • Light loss • Starting, particularly 25W lamps Gerry Cornwell Lighting

  7. Technical Issues • Lamp Issues • Induction • Very long life (+70,000 hrs) • Higher efficacy (+80 LPW) • Not affected by frequent switching • Not affected by cold temperatures • Assuming appropriate luminaire Gerry Cornwell Lighting

  8. Technical Issues • Lamp Issues • HID: High Pressure Sodium • Long life (+24,000 hrs) • Higher efficacy (+90 LPW) • Cannot be frequent switched • Not affected by cold temperatures Gerry Cornwell Lighting

  9. Technical Issues • Lamp Issues • HID: Metal Halide • Long life (+16,000 hrs) • Higher efficacy (+80 LPW) • Cannot be frequent switched • Not affected by cold temperatures Gerry Cornwell Lighting

  10. Technical Issues • Lamp Issues • LED • Long life (+70,000 hrs) • Higher efficacy (+80 LPW) • Can be frequent switched • Not affected by cold temperatures • High initial cost Gerry Cornwell Lighting

  11. TAF LightSavers Pilot • Parking Garages • Two underground garages in residential buildings • Using HPS luminaires on 24/7 • New T8 fluorescent luminaires with integral occupancy sensors, 2 light levels • New LED luminaires with integral occupancy sensors, 2 light levels Gerry Cornwell Lighting

  12. TAF LightSavers Pilot • Results • Light levels lower but within IES standards • Appearance brighter due to improved light colour (white light) • No negative reaction to sensor operation by residents • Energy savings for lights only +57% • Energy savings for OS +13% • Total energy savings +70% Gerry Cornwell Lighting

  13. Matrix Gerry Cornwell Lighting

  14. Conclusion • System Integration • This is not an easy retrofit project • Essential that lighting, security and life safety systems are integrated • Example: in the event of a fire alarm, all sensors are by-passed or activated ‘on’ • Garage projects typically incorporate renewal issues Gerry Cornwell Lighting

  15. Questions? • Thank you… Gerry Cornwell Lighting
