• Luminaire Level Lighting Controls (LLLC) Market Characterization and Baseline Report
  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. Recommendations: 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.

• Dimming Systems Characteristics
  Northwest Energy Efficiency Alliance commissioned a study to delineate the characteristics of 18 dimming systems as part of its Luminaire Level Lighting Control initiative. In theory, adjusting the light level by dimming 15 percent at the control station will have that intended effect (light level or power consumption reduction) at the light source or driver. In practice, this rarely happens. The study found that each ballast’s response to a linear control signal input varied and was not linear. The variances ranged from minor (plus/minus 2 percent) to significant (plus/minus 18 percent). This has implications for utilities in forecasting the anticipated energy savings of a lighting control system.

• Luminaire Level Lighting Controls Market Baseline Report
  Northwest Energy Efficiency Alliance (NEEA) is currently developing an initiative to accelerate the adoption of luminaire-level lighting controls (LLLC), an integrated lighting control approach that combines multiple control schemes to potentially provide 50 to 60 percent energy savings with low installed cost, ease of retrofit in existing buildings, and performance compatible with high efficiency technology such as LEDs. This report forecasts that annual LLLC sales will increase rapidly in the first 10 to 15 years, and then reach an inflection point as the market saturates with networked controls technologies. The report also forecasts that the sales will grow at an average compound annual growth rate (CAGR) of 37% for the first 10-year period and at a CAGR of 15% for the next 10-year period, with 20-year average of 25%. The largest markets for LLLCs reside in the office buildings and warehouses.
