50 Years of Lighting Control


3/30

Why Is Lighting Control Important?


4/30

Confidential

Did you know that buildings consume more than 39% the total US Primary

Energy in the United States?

Energy ConsumptionThe Landscape

28% of energy in Commercial buildings is consumed by lighting.

DOE Ruling Oct. 19, 2011: All states mustadopt an energy code as stringent as 90.1-

2010 by Oct. 18, 2013.

Energy codesASHRAE 90.1

New Construction and Additions

All commercial type buildings includingresidential structures of 4 or more stories

Interior and exterior lighting

Lighting Alterations of more than 10% of

the lighting load


7/30

Lighting controls in Energy codes/standards

Key mandatory lighting control requirements (summary of the big 3

standards/codes): 90.1 2010, IECC 2012, T24 2008 Automatic shut-off (occ sensors, timeclocks)

Space Control (dimmers, switches connected to timeclocks, occ sensors)

Stairwell lighting control (occ sensors, dimming ballasts)

Parking garage lighting control (occ sensors, daylight sensors, timeclocks,dimming ballasts)

Daylight zone control (daylight sensors)

Light reduction controls (dimmers, pre-set scene controls, bi-level switching)

Exterior lighting control (daylight sensors, timeclocks)

Functional testing of controls

Receptacle control

Watts per ft2incentives for additional controls

1. Incandescent > fluorescent lighting

2. T12 fluorescent > T8 fluorescent

3. T8 fluorescent > T5 fluorescent or LED

4. 32 W lamps > 28 W lamps

5. Delamping (ie. Make 3 lamp fixtures 2 lamps fixtures by simplyremoving 1 lamp)

10 Energy Saving Lighting Control Strategies

When used together these strategieshave created saving opportunitiesgreater than 70% lighting energy

savings and regularly achieve savings

greater than 60%.1

Benefits of Using Simple Wireless Controls

Easy to install and program Wireless communication, reducing wiring labor andmaterials

Default functionality fits many applications (no

programming) Simple button-press programming, no factory

commissioning required

Cost Effective Saves Installation Time... Saves Money! Saves Materials Saves Money!

Saves Energy Saves Money!


23/30

Application: Private Office

Design Goals: Personal control

Automatic shutoff of lights when the room is empty Daylight harvesting Task lighting control Appliance Control


24/30

Application: Private Office

Maestro Wireless switch easily replaces existing wall switch PowPak plug-in appliance module and MRF tabletop dimmer control plug loads One RPS occupancy sensor communicates with all load controllers


25/30

Application: Stairwell

Design Goal Example: Minimum light level at all times (15%)

Unoccupied light level 75% At least three fixtures go to occupied level when person enters

stairwell Not capable of turning off from any control beside breaker
