Case Study: Lutron Helps Glumac Engineer
for Sustainability

Glumac prides itself on being “Engineers for a Sustainable Future.” Their new Portland office on the 16th floor of the Standard Insurance Center is a testament to this commitment, reflecting both a sustainable building retrofit and an open-office layout for a more collaborative, teamwork oriented experience. Glumac relied on Lutron retrofit solutions to ensure a cost effective, efficient light control system that would contribute to LEED certification. Glumac’s new offices expect to achieve LEED Platinum certification for commercial interiors as a result of their efforts.


The new office space is bathed in sunlight – a great asset to employee morale, but also a challenge in terms of workplace lighting, especially within the context of an open-office design. The light control system in the space had to manage both daylight and electric light to achieve three goals:

  • Create an aesthetically pleasing design space
  • Deliver adequate and proper lighting for the employees
  • Set the standard for energy efficiency in building renovations

Glumac lighting designer, Carlos Inclan, says that when he specifies dimming, he likes to rely on Lutron controls. “They are of highest quality, easy to work with, and the wireless option helps me keep installation costs within budget. Anyone can just reduce light levels to save energy, but that’s not always best for the employees.

My goal is to deliver comfort first, and make sure that the system saves energy, too. Lutron helps me do both,” explains Inclan.


Throughout the space Lutron solar-adaptive shades automatically adjust according to the position of the sun, eliminating glare on work surfaces and reducing heat gain while preserving views. Wireless daylight sensors and digitally addressable ballastsautomatically adjust electric lighting to ensure that each area has the right amount of light for maximum comfort and productivity. 

Wireless vacancy sensors are installed throughout both open and private offices to ensure that lights are off when a space is unoccupied, but can be turned on when employees need more light. Davis explains this basic design premise, “In spaces with abundant daylight, people, not sensors, should turn on the lights. The best sensor ever developed is the human eye.” If the space layout changes, sensors can easily be moved without new wiring and without incurring expensive installation and programming costs.

Quantum® Total Light Management™ system controls all the lights, shades, daylight, and vacancy sensors throughout the space, and is tied into the building management system to deliver accurate, real-time lighting energy data.


Glumac reports initial average lighting energy use of 0.32 Watts per square foot — well below the designed connected load of 0.68 Watts per square foot. During the first 2 months of occupancy, this has been reduced to 0.24 Watts per square foot, attributable largely to the ease with which changes and modifications can be made to the control system.

The system aims to reduce lighting power density by 47% compared to state of Oregon allowances.
