Energy-Saving Light Control Strategies

Intelligent lighting control offers a significant energy-saving opportunity. Despite the fact that most lighting is energy-efficient fluorescent, the number-one source of energy consumption in any building is still lighting. Energy-saving light control strategies implemented using the Energi Savr Node™ with Softswitch® module can save up to 40% of the lighting energy used in your building.

Occupancy/vacancy sensing

Description: Turn lights off when space is unoccupied; turn lights on when someone enters.

Best applied in: Enclosed areas such as meeting rooms, offices, classrooms, and corridors.

Typical lighting energy savings: 15%¹

(Diagram description: A bar chart showing electricity usage and savings over a day. Usage is high when lights are on, and savings are achieved by turning lights off when unoccupied.)

Daylight harvesting

Description: Switch zones of light off during the day to take advantage of available daylight.

Best applied in: Areas with large windows or skylights, such as perimeter offices, classrooms, malls, and atriums.

Typical lighting energy savings: 15%²

(Diagram description: A bar chart showing electricity usage and savings over a day. Usage is reduced by dimming or turning off lights when sufficient daylight is present.)

Timeclock scheduling

Description: Automatically adjusts lights at certain times of the day or in relation to sunrise and sunset.

Best applied in: Areas such as stairwells, meeting rooms, offices, and classrooms.

Typical lighting energy savings: Variable

(Diagram description: A bar chart showing electricity usage and savings over a day. Lights are scheduled to be on or off at specific times, or based on sunrise/sunset.)

Combine lighting control strategies to maximize efficiency

When timeclock scheduling is used in combination with Lutron® sensors, the system can deliver lighting energy savings exceeding 40%.

Potential lighting energy savings when combining all light control strategies: 40%+

Codes and Standards

Define Your Space

The appropriate lighting control solution is defined by the needs of the space. The following steps help to answer key questions and drive you to the ideal lighting control solution.

Steps to Plan and Design an Energy-Saving Light Control System

1. Step 1: Energi Savr Node™ Selection

   A Determine the number of zones (independently controlled groups of fixtures) in the space.

   B Determine the number of Energi Savr Node with Softswitch® modules (each module can control up to 4 zones).

   See pg. 12 for all Energi Savr Node with Softswitch module options.

   See pg. 13 for QS sensor module (required for wireless integration).

2. Step 2: Energy-Saving Light Control Strategies

   A Determine if the space requires automatic shut-off control or occupancy/vacancy sensing (wired or wireless).

   B Determine if the space requires daylight harvesting (wired or wireless).

   C Determine which timeclock, if any, will be connected to Energi Savr Node with Softswitch module:

   • QS Timeclock
   • GRAFIK Eye® QS Wireless
   • Other manufacturer's timeclocks
   • Building management systems

   See pgs. 14-19 for all energy saving light control options.

3. Step 3: Control Selection

   Determine the type of wall control required and/or if there are additional points of control needed in the space.

   See pgs. 20-22 for all control options.

4. Step 4: Programming

   Determine what programming option suits your needs:

   A Out-of-the-box: For simple applications, preconfigured modes reduce installation time and eliminate system programming.

   B Manual programming: Assign components and configure a system with button-pre programming (For smaller systems using only one Energi Savr Node with Softswitch module).

   C Apple iPhone®/iPod touch® App: Easy and intuitive system programming application designed for the iPhone® or iPod touch® mobile digital devices (For larger systems using multiple Energi Savr Node with Softswitch modules).
