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.
Seattle’s Pacific Tower was an iconic building with a big facility maintenance challenge: its older systems were inefficient and falling short in meeting occupants’ expectations. After the Washington Department of Commerce signed a 30-year lease to take over Pacific Tower, the team wanted to implement bold system upgrades and energy conservation measures to bring the building into the modern era and provide a better lighting experience for occupants.
Seattle’s South Lander Business Park boasts a variety of tenants from small retail spaces to large warehouses – all with differing lighting needs that may change over time. Starting in 2016, the owners knew they needed to upgrade their outdated fluorescent lighting to something more adaptable, flexible and cost-effective. The answer? LED fixtures with luminaire level lighting controls (LLLCs).
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.
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.
