Safeco Field , Seattle, WA, is the first Major League Baseball stadium to make the transition to an LED sports lighting system. This historic project took two years of planning and multiple pilot experiments that involved the coaching staff, the broadcasting crew, lighting designers, the marketing team, utility engineers and the landscape crew. This session will provide an overview of how Solid-State lighting technology was implemented to improve the lighting environment for athlete performance, the fan experience and broadcasting quality.
- Participants will leave with an understanding of the current state of research and design applications for circadian lighting
- Participants will be exposed to a debate that examines both common ground and major differences between the scientific approach/study and grounded design application of circadian lighting.
- Participants will understand the current luminaire and controls manufacturing environment and how manufacturers are challenged to develop products for an industry where the technology is moving faster than the science.
- Participants will learn what disclosures are recommended to increase trust amongst specifiers, designers, and building owners.
Lighting is fast becoming the hub of a shift toward smarter, more connected buildings. Light fixtures with sensors have become a wireless network of nodes that are the superhighway of smart buildings, collecting and delivering big data from buildings everywhere. This makes it more critical than ever to embrace the changes in lighting that are required to meet the demand for smart, connected buildings.
The Webcast will cover what has become a widely-accepted concept that lighting applied appropriately can bring joy and convenience to people, and also enhance wellbeing and productivity and even accelerate healing. The presentation will summarize the research on the enhancements to human life attributable to tunable lighting. The Webcast will address the technology involved in tunable lighting including LED components, driver electronics, and control schemes for both light output and color temperature (sometimes called Kelvin changing). The talk will cover existing tunable light sources including retrofit lamps that carry small price premiums relative to non-tunable sources. Moreover, the discussion will project ways that what the presenters call human centric lighting can make the complete transition from the R&D stage to commercialization.
Steven Lockley of Harvard University noted that light has a powerful effect on our bodies, mainly by impacting our circadian rhythm. He explained that this process is mediated in large part by special nonvisual cells in the eye that are particularly sensitive to light in the blue range, at a peak of 480 nm, and that SSL’s spectral tunability gives it a considerable advantage in this regard over other lighting technologies. Lockley noted that office and shiftwork studies conducted during the day and at night show improvements in alertness and performance with higher-CCT (correlated color temperature) light, and pilot studies of students show the benefit of higher-CCT lighting on concentration and performance. He described studies underway to test the effects of a prototype LED polychromatic lighting system on pre-sleep sleepiness, post-wake alertness, and circadian phase resetting for the Space Station.
John Hwang of Planled said we have an historic opportunity to transform lighting into something much greater than it’s been. He explained that with SSL, lighting can have a positive impact on health in addition to saving energy and money. Hwang described a current project working with the Seattle Mariners to create a tunable lighting system for the team’s Major League baseball stadium, the idea being to create an optimized playing environment. He said the high salaries paid to professional athletes more than justify the cost of such a system. Hwang also discussed a comprehensive guidebook on SSL sports lighting applications, which he’s creating in tandem with the Green Sports Alliance and the HumanCentric Lighting Society, and in addition he talked about the use of lighting to create favorable outcomes in healthcare settings.
Motivation for environmental change should be human-centric.
During one of the educational sessions, “Steps to a Healthy Lifestyle: Circadian Lighting Discussion,” speakers Dr. Shadab A. Rahman, Ginger S. Rucker and John Hwang discussed how interior lighting choices can affect circadian rhythms during sleep.
They said simple changes, such as different lighting, can improve health and wellness for all occupants, from hospital patients to athletes in a sports stadium. It’s important to examine how new technologies will be applied and how they can affect users who regularly interact with them.
The sports greening movement provides a unique opportunity for international harmonization in effective environmental action. By collectively leveraging the cultural and social influence of sports, our movement unifies, convenes, and inspires communities around the planet to PLAY GREENER. As the influence of our work grows, so too does the opportunity and our ability to scale our impacts and make lasting, positive change.
