What is Wireless Lighting Control

A tremendous amount of our global energy use comes from lighting—in fact, lighting accounts for up to 40% of the electricity used in commercial buildings today. It should come as no surprise that much of this energy is used inefficiently. For example, lights in offices often remain on when the office is empty, or at full power even though sunlight is available. Throughout a typical day, most lights provide more illumination than their users desire, need, or can even perceive.

Lighting control solutions aim to solve this problem by vastly reducing energy consumption while providing users with greater control. This is achieved through a set of strategies that use sensor technology to deliver the optimal level of light to all users at all times.

Wireless lighting control goes a step further, by making these strategies more easily achievable and powerful, at a lower cost. With wireless lighting control, an intelligent lighting system provides greater control to users, automates lighting decisions, and minimizes wasted energy. Ultimately, this helps building projects meet government regulations and LEED certification, as well as save money and improve sustainability.

Advanced lighting control 

Lighting control systems use automated intelligence to deliver the required illumination level, where you want it, when you want it. Luminaires can automatically turn on, off or dim at set times or under set conditions. Users have control over their own illumination levels to provide an optimal working environment while preventing energy waste from over-illumination. 

Lighting control systems include some or all of the following:

  • on/off and dimming controls
  • occupancy sensors to detect whether rooms are occupied
  • photosensors to detect the current illumination levels provided by natural and/or artificial light 
  • scheduling that turns on, off, and dims luminaires at preset times
  • a centralized control system interface (such as a wall panel or computer software) to manage all of the above 
  • a method of communication between the lighting equipment and control system
  • a method of measuring, displaying, and responding to lighting energy usage

Lighting control systems vary widely according to the technologies used to complete these tasks, as well as their degree of difficulty and cost. Historically though, the more system-wide controls and advanced strategies that are used, the greater the complexity, which often makes these solutions difficult or even impossible to implement across large-scale environments.

Removing the wires

Wireless is especially relevant for retrofit situations, where access to wires within walls and plenums, and introduction of new wires, can be difficult, expensive, and in some cases impossible. In retrofits, wireless enables the addition of powerful control strategies without the cost and disruption of rewiring. Removing communications wires also provides more flexibility in terms of where controls and sensors can be placed, and can make it more affordable to include additional controls and sensors in the network (enabling more granular information about illumination levels and therefore more accurate control).

Wireless solutions are also ideal for large companies or government departments that have installations covering multiple floors or buildings. Through wireless networking, the lights, switches, sensors, and other elements of the system all communicate with each other throughout a room, building, or across an enterprise, and can be controlled and managed centrally for a system-wide view of operations, current power usage, savings, and more.

Lighting Control Solutions for Commercial Offices, High Bay and More

The commercial and government office segment represents possibly the largest opportunity for advanced lighting control retrofits, with over 10 billion square feet of lit floor space in the U.S. and the greatest lighting energy usage of any building type.


Lighting Control Solutions and Strategies

Lighting isn't the only energy load that can be controlled by an intelligent wireless network - plug loads, blinds, HVAC devices and more are quickly taking advantage of the power of wireless networking within commercial buildings. Wireless lighting control can reduce energy consumption and costs without inconveniencing tenants or affecting their working environment, simply by using your lights more efficiently.


Scheduling Commercial Lighting - Daintree Networks

Our intuitive Web-based software walks the user through creating and modifying scheduled events, which can be applied to either a single day or to multiple days, and also to a single zone or to multiple zones. Scheduling not only saves energy and money, it also helps buildings to comply with the "automatic shut-off of building lighting" requirements of energy codes such as ASHRAE 90.1 and California Title 24.


Using Occupancy Controls for Commercial Lighting

Many of today's commercial lighting and building automation systems have already begun to use occupancy sensors to turn lights on and off based on whether or not an area is occupied. The idea behind occupancy control is simple and elegant: use a sensor to determine when people are in the vicinity, and reduce or eliminate unnecessary lighting if areas are empty.


Daylight Harvesting Reduces Lighting Costs

Automated daylighting systems detect daylight levels by using photosensors, and automatically dim or brighten electric lights as required to reach a consistent lighting level throughout the day. A number of automated daylight harvesting solutions are available, consisting of dimmable luminaires or ballasts, photosensors, and lighting control software.


Energy and Demand Management - Daintree Networks

By logging all lighting activity and energy use, Daintree is capturing valuable data that can be used to make better decisions, measure and verify savings, and drive new demand-based programs. By putting energy monitoring tools and usage data in the hands of facility managers, they can communicate with utilities and take advantage of greater cost savings offered by these programs.
