Energy-Efficient Lighting Controls Stop Energy Waste
It’s our vision at Watt Stopper/Legrand. We make buildings and homes more energy efficient through lighting controls. With Watt Stopper/Legrand, you’ll find everything you need to make your lighting controls project a success. Our comprehensive range of products is just the beginning.

Lighting Controls Overview



With mandatory energy code requirements on the state, regional, and local levels, virtually every facility faces lighting control requirements. And now with new federal tax incentives available under EPAct 2005, understanding, meeting, and exceeding code requirements represents a money-saving opportunity as well.

These are the primary motivators for using lighting controls, as lighting systems account for an ever greater percentage of total energy usage. Currently, almost half of an average building’s energy usage comes from lighting. Next to heating and air conditioning systems, lighting systems account for the greatest energy consumption and costs.

Discover the benefits of lighting controls
Each year, more organizations implement lighting controls because they recognize the wide range of benefits:

• Energy Savings - More than 30%, reducing building operating costs by 10% or more
• Convenience - Transparent operation requiring little or no adjustment and no disruption to homeowners and building occupants while operating; added convenience of automatic
  controls for homeowners, building occupants and facility management personnel
• Flexibility - Accommodates changes in space configuration, schedules, and activities
• Information - Identification of energy usage data, facilitating the ability to divide overhead costs if necessary and as appropriate, pinpoint energy usage for management
• Productivity - Increased employee productivity as a result of optimal lighting; and for homeowners, the elimination of repeatedly turning off lights that others have left on
• Safety & Security - Ensures operation of critical lighting for occupant safety, including continuous operation of emergency lighting and exit signage, and effective lighting of exterior parking facilities, walkways, or tunnels
• Sustainable Building Practice - Enhances energy-efficient building performance for sustainability programs (i.e., GBI - Green Building Index)

Lighting Controls Strategies

In most cases, the control strategy will include automatic operation of the lighting, taking into account the needs of the space’s occupants and what might be necessary to comply with mandatory energy codes. Further control strategy decisions will involve what devices will be employed to satisfy those needs.

Control technologies, on the other hand, usually refer to the type of device that will be used to carry out a specific strategy and what method the device will use to operate (passive infrared, ultrasonic or dual technology sensors, timers, daylighting controllers or lighting control panels).

Occupancy-based Control
Switching lighting off and on in response to the occupancy of a particular space is not dependent on time intervals or scheduled periods, but responds to the individual usage of a controlled space.

Different sensor technologies to fit different applications:-

Passive Infrared (PIR) - detects differences between human body in motion and background space
Ultrasonic - capable of detecting occupancy in low-activity area
Dual technology - combination of PIR and ultrasonic technologies

Vacancy-based Control
Switching lighting off in response to a space becoming vacant is not dependent on time intervals or scheduled periods, but responds to the individual usage of a controlled space. This kind of device is currently most often used to meet California’s Title 24 requiremnts for residential buildings.

Scheduled Control
Managing lighting according to time schedules based on when buildings are open/occupied and closed/unoccupied.

Load Shedding
Reducing a facility’s lighting load to achieve an overall reduction in demand, usually at peak usage times, such as midday

Daylighting Control
Adjusting the output of electric lighting in a daylit area adjacent to a window or skylight via a photosensor that detects light levels in the space (can be ON/OFF or dimming control)

Dimming Control
Adjusting lighting levels to achieve desired lighting effects or appropriate light levels for different occupant activities

To reduce the economic burden on homeoverners and commercial enterprises, and stem the increasing strain of spiraling energy usage on a national electric grid, lighting controls are becoming a standard design practice. In 2002, the federal government adopted mandatory lighting control provisions developed by ASHRAE as the standard with which state energy codes must comply.The fact is, lighting controls work effectively, making their usage common practice in today’s world.
