NEW! Optional Tour of PNNL Lighting Science & Technology Lab

On Thursday, there will be an optional tour of research experiments at  Pacific Northwest National Laboratory’s Lighting Science & Technology Lab. Space is limited! Register early to secure your spot.

$25 Tour Transportation Cost

PNNL is a leading laboratory for lab- and field-based lighting research. Come join us after the end of the event to take a look at some of the following cutting-edge experiments: 
  • Spectrally Tunable Lighting Facility – Large room with 24-channel tunable luminaries offers world-class capability for understanding the effect of variation in light source spectrum on performance, wellbeing, mood, brightness perception, visual fatigue, and more. 
  • Glare Apparatus – Custom-built apparatus with 54 color tunable luminaires with automated individual control allows for matching and adjustment of discomfort levels due to glare. 
  • Uniformity Apparatus – Automated device for varying the luminance distribution of a luminaire aperture and capturing measurements with a luminance meter or high dynamic range imaging setup. 
  • Variable Height Ceiling with Modular Room – Two variable height ceiling grids enable installation and evaluation of various types of electric equipment powered by different electrical distribution architectures. A modular room setup under one of the variable height ceilings provides an enclosed space for lighting measurements. (These are subject to change) 
Foreign Nationals: Lawful Permanent Residents (LPR) of the United States must present a valid LPR card or evidence of lawful status if waiting for an LPR card to be issued. Non-U.S. citizens who are not LPRs must provide valid passports and visa documentation, including an I-94 Departure Record or an applicable passport admission stamp. 
If you are a foreign national interested in attending the tour, please register by attaching the required information, and someone on staff will be in contact with you to confirm registration.

Ecological Considerations

Creating sustainable luminous environments demands a thorough understanding of lighting’s impacts on ecological systems. Ecology invites us to examine the complex relationships between organisms, including humans, and their habitats, from individual life forms to the global biosphere: an intricate network of connections that underscores the critical need for an integrated approach to lighting design. In this panel, we bring together a diverse group of practitioners, researchers, and lighting manufacturers to foster a meaningful discussion on reducing the lighting industry’s ecological footprint while enhancing its contribution to environmental balance. We aim to extend the conversation beyond the traditional focus on energy efficiency, focusing on the latest research and practices that demonstrate lighting’s capacity to reduce carbon emissions, promote responsible outdoor lighting at night (ROLAN), and address broader ecological concerns. This session serves as a platform for deepening our collective knowledge of sustainable lighting practices and reinforcing our commitment to environmental stewardship.

Design for Resiliency

The improved efficiency and robustness of LED lighting enables greater resiliency in lighting systems, and this session will explore the latest thinking on design for resiliency. Reduced power consumption means there is reduced reliance on power sources and greater potential for local renewable energy or battery power. As a critical service, the resiliency of lighting systems should be considered as part of the lighting design, selection, and installation process. Considerations of resiliency include mechanical and electrical resiliency, usability, and reliability in the face of natural and man-made adverse events.

L-Prize Innovation

The DOE L-Prize competition is designed to spur ground-breaking innovation for next-generation lighting in commercial buildings. DOE deliberately set the bar high, with ambitious innovation goals for efficiency, sustainability, connectivity, and more. Six winning prototypes demonstrated extraordinary performance and capabilities, and this session will gather these leading-edge innovators to explore what they see as the biggest remaining challenges, and what this prize teaches us about future research needs.

Topic Tables

This is your opportunity to provide input to IES and DOE! Registered attendees will select a single research topic from the provided list for small-group discussion. Each group will examine why this topic is important and what the technical challenges are. Some “questions to consider” will be provided for each topic to help spur the discussion. The inputs from each group will be used to guide planning for future IES and DOE research activities as well as IES technical committees.

Light and Health: Translating Research into Recommendations

For more than two decades, the academic research community has been investigating the impact of light on human health and well-being. While this remains an active area of research, new recommendations for indoor light exposure have emerged, considering the sensitivity of the human circadian, neuroendocrine, and alerting responses to light. This session provides an overview of the latest research findings, how these findings have been integrated into current recommendations for indoor light exposure, and finally, how these recommendations translate to lighting design and practice.

Next-Generation Lighting Tools

As the lighting industry evolves, so do our tools. Artificial intelligence is impacting design and is poised to be integrated into industry practice and processes. This session will address new products and software that are adapting to meet new market expectations. The internet, electronics, and telecom industries are converging with lighting with the intent of adding it to their offerings. Trends including decarbonization, lighting for health, and a circular economy are triggering new standards and regulations that provide guidance and guiderails for lighting professionals. Join knowledgeable experts for a discussion of the next generation of tools available and needed for architectural lighting to meet current and future demands.

Novel Methods for Post-Occupancy Evaluations

Post-occupancy evaluations are somewhat common practice for measuring the success of a lighting project, testing a design hypothesis, or identifying lessons learned for future designers. Historically, these evaluations have linked relatively static estimates of lighting quantities to occupant feedback collected from surveys or interviews; however, new technology has enabled more sophisticated assessments of increasingly capable daylighting and electric lighting systems. This session will highlight novel methods for characterizing occupant light exposure and discuss how these methods can deepen our understanding of the relationship between lighting conditions in real-world applications and occupant outcomes.
