The Future of Efficient Lighting: Luminaire Level Lighting Controls
Combining LEDs with integrated controls and sensors within each fixture, Luminaire Level Lighting Controls (LLLC) offer commercial buildings an integrated solution that will improve building performance and occupant satisfaction, deliver maximum energy savings, and enable long-term flexibility with tenants and space usage.
- Energy Cost and Savings: LLLCs use 25 to 75 percent less energy than non-controlled fixtures. And with less wiring and simple, out-of-the box set-up LLLCs enable even greater time and labor cost savings.
- Long-Term Flexibility: Adaptable for changes in space usage, fixtures with LLLCs reduce the cost of change-over to new tenants. Simply re-group to the new lighting layout and adjust settings for new tenants.
- More than Energy Savings: Many LLLC systems enable value benefits beyond just energy savings, including asset tracking, space utilization, enhanced security and more.
Customizable marketing materials are available for education on the benefits of Luminaire Level Lighting Controls. These materials include an LLLC FAQ, infographic, building type-specific one-pagers for hospitals, schools and offices, and more.
In early 2015, after a number of concerns about the lighting in its Bothell location were raised, PSE evaluated their existing lighting system – ultimately recognizing the opportunity to improve occupant comfort by piloting Luminaire Level Lighting Controls.
Ecotope, an energy efficiency engineering and research firm in downtown Seattle, outgrew their office space and decided to lease the third floor of a 3.5-story mixed-use building. The building’s existing heating and cooling equipment featured an all-electric, variable air volume (VAV) rooftop unit (RTU) with electric resistance terminal heat in the individual zones including open office areas, conference rooms, a shared breakroom and a server room.
Although a two-story, 1930s airport terminal building in Seattle underwent a major renovation in 2002, the HVAC was largely untouched. The duo of large, multizone rooftop units (RTUs) were left in place, with a third unit of the same type added during the renovations. This inefficient HVAC system wasted energy and money, led to inconsistent temperatures, and caused severe occupant discomfort.
The owners of a popular pizza restaurant in Corvallis, Ore., experienced high energy bills and poor ventilation and airflow — a particularly vexing issue for businesses with commercial kitchens. Many culprits were to blame for these issues, including leaky and poorly insulated walls, large make-up and exhaust air openings from the venting system that serves the pizza oven, and a number of additional air supply and exhaust pathways that weren’t in service but nonetheless resulted in significant air leakage.
The aging HVAC system at the Oregon Department of Fish & Wildlife’s district office complex in Corvallis resulted in high energy costs and limited comfort control for tenants. The HVAC system struggled to provide consistent temperatures across 13,200 square feet of conditioned floor area, made up of four separate buildings sharing concrete walls and the various zones within the buildings. The building managers knew any retrofit project would be difficult due to the complex’s unconventional arrangement.
How do I know if a system is considered Luminaire Level Lighting Controls?
All LLLC systems have the following core capabilities:
- Occupancy sensing
- Daylight harvesting
- Continuous dimming
- High-end trim/task tuning
- Controls persistence
Design Lights Consortium (DLC) maintains a Qualified Product List (QPL) for Networked Lighting Controls that includes a filterable subset for Interior Lighting and LLLC systems. New qualified products are frequently added to this list; check the QPL regularly for the most up-to-date information on products that are considered LLLC systems.
