In early 2014, the Northwest Energy Efficiency Alliance (NEEA) began developing its Luminaire Level Lighting Control (LLLC) Initiative for office buildings and warehouses. LLLC systems have a sensor in each light fixture that senses occupancy, determines optimal light output, and in some system models, reports out energy use and other data. In addition to reducing energy use, LLLCs offer non-energy benefits such as improved worker productivity and health. In 2015, NEEA contracted with Research Into Action and its subcontractor, Energy 350, to uncover market barriers to LLLC adoption, and recommendations to overcome them.
1) Train installers
2) Include LLLCs in commercial energy codes
3) Engage with lighting designers on specifying LLLCs
4) Leverage other NEEA initiatives’ distribution channels
5) Explore the concept of “lighting as service” as a way to deliver LLLCs to the market
The study also found that current commercial market penetration of LLLC systems is 0.5 percent in offices (large, medium and small) and 0.8 percent in warehouses. The study projected that between 2016 and 2035, market penetration will increase to 50 percent in new construction and major renovations, and to 18 percent in retrofit regional stock.
