Lighting

 

Advanced lighting controls, field data, and demonstrations

Lighting upgrades have long been a target of utility programs. Programs historically focused on prescriptive rebates for luminaires and occupancy sensors. Because of code changes and rapid development of lighting control technology, program managers are focusing more on lighting controls for next generation programs.

Advanced lighting controls include a combination of control strategies such as daylighting, occupancy, task tuning, and scheduling. Lighting controls can also incorporate demand response facilitated by dimming and connect to other building systems such as HVAC or plug loads.

We conducted ground-breaking field research to quantify the extent of over-lighting after LED retrofits, estimate additional lighting savings from task tuning, daylighting, occupancy censors, and integrating other buildings systems. Our findings are informed by rigorous measurement and verification methodology and extensive stakeholder engagement with energy efficiency program managers, manufacturers, sales reps, distributors, lighting designers, and installation contractors. The goal is to inform future efficiency programs in order to achieve higher energy savings and improved occupant comfort.

Office lighting
Lighting in commercial buildings has been the target of energy efficiency programs for years, with the primary strategy one-for-one fixture replacement. However, recent changes to federal standards for fluorescent lamps and more stringent building and product codes, have eroded these program savings. Market changes are forcing energy efficiency programs to look beyond efficacy-based, one-for-one replacement incentives. Research in other Midwestern states shows that LED-lit spaces in commercial buildings are often over-lit, which leads to excess energy usage and dissatisfied occupants. More
Keller Center
Discover daylighting benefits in a beautiful historical building What if you could experience the outdoors—minus extreme weather—indoors? Slipstream’s experience with daylight design and advance building techniques brings the wellness benefits of natural light into the Keller Center in Chicago. People working inside this Edward Durrell Stone postmodern masterpiece now have access to the Harris Family Forum at the nucleus of the building. This four-story atrium is the building’s most prominent feature and connects to the outdoors via skylights. More

On behalf of Focus on Energy’s Environmental and Economic Research and Development Program (EERD), Slipstream collected information from Wisconsin businesses on their light levels and associated lighting system characteristics. This information will help Focus on Energy address savings opportunities from optimizing light levels by identifying appropriate program offerings and resources. More
daylight controls
Proper commissioning can lead to energy savings—often 60% or more Daylighting control, or daylight harvesting, has become a common energy savings strategy in many sustainable building projects, but several barriers still prevent successful implementation of this strategy in mainstream construction. Considerable effort is expended in the architectural and lighting design of daylighting controls, with actual execution being an afterthought. More

Task tuning can lead to energy savings without loss of occupant comfort. Task tuning is one form of lighting control that can be used in commercial buildings to save energy. It involves dimming lights in a space so that the average illuminance at the working plane is appropriate for the type of use in that space. More
