Glumac Wins IES Lighting Control Innovation Award of Merit

The Lighting Control Innovation Award was created in 2011 as part of the Illuminating Engineering Society’s Illumination Awards program, which recognizes professionalism, ingenuity and originality in lighting design. LCA is proud to sponsor the Lighting Control Innovation Award, which recognizes projects that exemplify the effective use of lighting controls in nonresidential applications. In this award’s first three years, 34 projects were recognized with an Award of Merit and four with an Award of Excellence.

This month, we will explore the role that lighting controls play at the Portland, OR-based office of Glumac Lighting Studio. Lighting and controls design by Glumac. Photography by Bruce Damonte. Lighting controls by Lutron Electronics and Crestron.

Every luminaire has local dimming control and complete adjustability from a networked control system. This tunablity has reduced the 0.63w/sq.ft. connected load to a constantly monitored average of 0.23w/sqft during peak hours.

Each configurable conference space uses separately controlled recessed fluorescents, LEDs and suspended direct and indirect components to ensure functional flexibility.

Each conference space can be controlled with a single dimmer at room entry, a 5-button scene controller near the presenter’s screen, or individual fixture and shade control via an iPad.

In the café space, the direct/indirect fluorescent fixtures mounted above the architectural metal ceiling help highlight the ceiling while obscuring the fixtures.

In private offices, direct/indirect fluorescent luminaires are used within the rhythm of the exposed concrete structure. When ample daylighting is present, fixtures are automatically dimmed down as low as 1%.

Vacancy sensors throughout every space are turned on manually when needed.

20w LED pendants are integrated within chilled sails over collaborative tables in each working neighborhood.

General office space is lit with adjustable task lights at each workstation. A 40w fluorescent lamp delivers 80% of the light up and 20% onto the task surface. Luminaires are shielded to produce no glare when seated or standing. Project maintenance is simple and inexpensive with only three lamp types and easily accessible fixtures.

With motorized shades raised, daylighting allows task lights to dim automatically. Wireless dimming controls allow each user to set a level or turn fixtures off.

Controls decrease watts/ft2 usage by 77% below ASHRAE maximum, 74% below Oregon energy code limits, 63% below full connected load without controls and 1% below basis of design.

Budget:

Upfront costs for the lighting system were higher than a more traditional office system but were offset by the annual energy cost savings and utility rebates for such an efficient system.
