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.
This month, we will explore how daylight and electric lighting control combine to dramatically minimize energy consumption while providing maximum flexibility and good lighting quality.

The goal of the Bullitt Center is to drive change in the marketplace faster and further by showing what’s possible today. The era of harm reduction, half steps, and lesser evils is behind us. As a society, we need to be bold in ways that were once unimaginable.
How do you illuminate the “greenest building in the world”? Daylight…daylight…daylight! A massive overhang and operable exterior louvers control direct sun, reducing heat gain. The PV overhang
serves as the primary building energy source.
They also control glare and redirect the sun into usable daylight.
Every occupyable space receives daylight adequate to perform office tasks.
People need a view and every space is design to capitalize on a connection with the exterior.
During normal operating hours, 90% of the building electric lighting remains off or in a substantially dimmed state.
At night, vibrant white walls are simply, efficiently and effectively illuminated with linear LED to contrast with the warm wood ceilings. Task light with smartphone-controllable color tuning is provided at every desk.
With a tunable exterior sun shading system, transient and casual spaces are allowed to receive direct sun when available.
At night, these spaces transition seamlessly from daylight illumination to take on a soft feel with fully dimmable LED and fluorescent illumination. Bright floors and light walls help to minimize the amount of electric lighting needed. All lighting is dimmable and DALI controlled. Manual overrides give users full dimming control.
At night, the building sleeps. DALI Motion sensors turn entry lighting on as people approach and keep it off when the building is alone.
