Using Occupancy Controls for Commercial Lighting

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.

Occupancy control systems provide convenience, security, and cost and energy savings. 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 California Energy Commission estimates that using occupancy sensors to turn lights off when areas are unoccupied can reduce energy waste and costs by  up to 45%.

Not only does occupancy control reduce energy consumption and save 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.

Daintree Networks enables a complete and powerful occupancy control solution, through the use of wireless occupancy sensors. In addition to simply turning lights on when someone enters a room and off when they leave, the combination of occupancy and task tuning controls enable specific illumination levels to be set based on individual needs. For example, turning lamps on at 85% (instead of 100%) is a difference very few people will notice, and can reduce energy costs while improving the life of the lamps. 

Daintree-based systems can also combine occupancy control with other cost-saving strategies, such as scheduling and daylight harvesting, to further add to savings. And Daintree supports manual over-ride, which allows occupants to brighten (or dim) pre-set levels when they are performing tasks that require more (or less) illumination.

One of the benefits of  wireless controls is the ease of adding or moving sensors to fine-tune the system or collect more granular details about occupancy levels. Daintree-based systems also automatically identify new sensors, and intuitive tools make it easy to configure, manage and monitor your lighting system.

What is Wireless Lighting Control

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. 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.

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.

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.
