Topic: Emerging Technologies
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.

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 wellbeing. 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. Moderator: Morgan Pattison, SSLS, Inc.
- Steven Lockley, Harvard Medical School
- Renske Lok, Stanford University
- Lisa Ostrin, University of Houston

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. Moderator: Mark Lien, Illuminating Engineering Society
- Michael Davidson, Synapse Wireless
- Thomas Paterson, Lux Populi
- Eve Phillips, Capital One, formerly of Google AI
- Jon Sargent, Solemma
Lunch
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. Moderator: Andrea Wilkerson, Pacific Northwest National Laboratory
- Mike Martinez, Atelier Ten
- Shadab Rahman, Harvard Medical School/Brigham and Women’s Hospital
- Siobhan Rockcastle, University of Oregon
