Pacific Tower was an iconic building with a big facility maintenance challenge: its older systems were inefficient and falling short in meeting occupants’ expectations. The building management 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.
Luminaire Level Lighting Controls are lighting products with wirelessly networked integrated sensors, enabling luminaires within the system to communicate with each other. These systems provide multiple control capabilities in one package, from occupancy and vacancy sensing to daylight harvesting and data transmission.
The Solution: Luminaire Level Lighting Controls
The project engineer for Pacific Tower, Joe Moroni of McKinstry, researched the best lighting option to meet occupant needs. McKinstry and the project team decided the Enlighted System featuring Luminaire Level Lighting Controls (LLLCs) was the ideal choice, for these primary reasons:
- Long-Term Flexibility
According to Moroni, an LLLC system is an ideal solution for buildings like Pacific Tower with a variety of tenant types with different occupancy uses. From traditional office spaces to Seattle Central College’s dental and nursing school laboratories, each tenant is able to get the right lighting for their individual needs. “The system can be recommissioned without actually changing out any of the hardware or infrastructure,” commented Moroni.
- Granular Control
“The Enlighted System is adjustable down to the individual fixture and gives feedback to the operators in real time, based on the energy use and temperature of the space and occupancy of the space,” stated Moroni. “That sort of granular data is really helpful in achieving the types of aggressive energy savings that we’re going after.”
- Maximum Energy Savings
According to the Northwest Power and Conservation Council, office buildings that install LLLCs are seeing an average of 50 percent energy savings compared to non-controlled lighting fixtures. “This is a state-of-the-art lighting system,” says Stan Price, then-Executive Director for the Northwest Energy Efficiency Council, a building tenant since 2014. “We are probably getting the lowest-cost lighting services as we could expect from any office building. That, combined with a number of energy efficiency features, make Pacific Tower a great place for us to be a tenant.”
- Building System Integration
Lastly, the team had a special interest in integrating the building’s HVAC system with occupancy sensing. With the wide variety of tenant types in Pacific Tower, some spaces like classrooms and laboratories are only used sporadically throughout the day. Integrating the HVAC system with occupancy sensing through LLLCs allows for even more significant energy savings because the building isn’t actively heating and cooling those spaces when they aren’t in use.
Recommendations when considering an LLLC system:
- Work with your utility. Utilities can serve as a key partner to help vet the technology and provide incentives that help offset project costs.
- Take into account the cumulative cost effectiveness created by the technology and equipment you are considering. Installing Luminaire Level Lighting Controls is a high return on investment improvement that can significantly cut down the time it will take to achieve payback.
