Lighting controls systems already exist in the market that turn lights off when spaces are unoccupied or when sufficient daylight is available. However, installing currently available systems involves wiring and can be an expensive proposition in already existing buildings.

CLTC partnered with Adura Technologies to develop a wireless integrated photosensor and motion sensor system that uses wireless communications to circumvent this issue, thus increasing the pool of buildings that could effectively benefit from lighting controls.

OBJECTIVE:

To commercialize a wireless integrated photosensor and motion sensor system that is energy efficient and cost effective

APPLICATIONS:

Commercial buildings, warehouse facilities, parking garages, schools, and other spaces that could benefit from wireless lighting controls

DESCRIPTION / FEATURES:

• No costly rewiring because system can be located wherever it is convenient
• Intelligent step-dimming an option; multiple possible control scenarios
  
• Link daylighting and occupancy controls to provide greatest energy savings
  
• Can be used with any ballasted or incandescent lighting system
  
• Individually addressable Light Controllers update data and accept commands in real time
• Web-based application provides monitoring, scheduling, and reporting

RESULTS:

• The system allows for the installation of controls systems to pre-existing light fixtures as well as luminaires involved in new construction.
  
• The system is robust and offers a large amount of programmability.
  
• It is expected to reduce installation and commissioning time by as much as 50% over standard industry practice for competing technologies.
• A retrofit project using this kind of technology could reduce office lighting by as much as 25%.
  

STATUS:

• Adura Technologies manufactures the LightPoint System.
• Other manufacturers also offer lighting control products, including EnOcean, Lutron, and
  WattStopper.
