1 Lighting Controls Made Easy Spring Seminar Mike Matour, National Energy Solutions Manager The Standard for Lighting Management Quality since Lutron Electronics NALMCO 2018 SPRING SEMINAR Mike Matour, National Energy Manager Lighting Controls made Easy Agenda Why Controls? Energy Conservation Measures Dimming Protocols - Retrofit Good, Better, and Best Solutions Advanced Controls 1

2 Why Lighting Controls? Quantifiable Tuning / Dimming Occupant Sensing Day-lighting Personal Control HVAC Savings Window Shading Demand Response Plug Load Control Other Benefits Productivity Maintenance Sustainability/LEED Property Value Flexibility Codes 8 Simple Light Control Strategies / ECMs High end trim/tuning: Set target light level based on occupant requirements in the space. Reduce HVAC load (3 for 1 rule) Occupancy/Vacancy Sensing: Automatically turn lights off or dim down when space is vacant. Integrate HVAC locally/digitally. Daylight Harvesting: Automatically adjust light levels based on the amount of daylight in the space. Scheduling: Lights automatically turn off or are dimmed at certain times of the day or based on sunrise or sunset. 8 Simple Light Control Strategies / ECMs (cont) Personal Light Control: Allow users in the space to select the correct light levels for the desired task. Controllable Window Shades: Allows users to control daylight for reduced solar heat gain and glare. Demand Response: Reducing lighting load at times of peak electricity pricing. Plug-load Control: Automatically turning task lighting and other plug loads off when they are not needed. 2

8 How do I control my LEDs? Typical Questions/Issues? -What dimmer do I need to control my LEDs? -Do I save energy by dimming LEDs? -Why do my LED have limited dimming? -Why doesn t my 34 year old lighting panel dim my state-of-the-art LED lighting? Single Zone Lighting Controls Multi-Zone Lighting Controls 8

9 Advanced Lighting & HVAC Control Systems Total Light Management What type of LED product am I using? LED Bulbs/T8 LED LED Fixtures Designed to replace standard incandescent or screw in CFL bulbs Standard Edison (E26) base sockets Integral drivers determine dimming performance (if dimmable) Variable in purpose (cove lights, down lights, 2x2, etc.) OEMs offer multiple driver options to support different control technologies and applications (dim vs. non dim, 0 10V vs. DALI) 9

10 What control type do I need? Line Voltage Dimming Forward Phase Analog 2 Wire Most common dimming method (150 million dimmers in use) Designed for resistive (incandescent, halogen) or magnetic lowvoltage (MLV) loads Installed base not intended for LEDs, performance issues and compatibility problems likely Hot (120/220/277V) Neutral Dimmed Hot What control type do I need? Line Voltage Dimming Reverse Phase Analog 2 Wire Typically used for ELV loads, sometimes perform better with LEDs Less likelihood of acoustic noise due to no repetitive peak current Smaller installed base, usually require a neutral wire Hot (120/220/277V) Dimmed Hot Neutral What control type do I need? Line Voltage Dimming 3 Wire Analog Fluorescent standard, control signal carried separate from power Precise, less prone to noise, but requires a third line voltage wire Universal voltage, high power factor, multiple control types available Hot ( V) AC Power Neutral Switched Hot (power) Dimmed Hot (signal) 10
