Webinar Schedule
PNNL: Real-world Application of Germicidal UV
Germicidal ultraviolet (GUV) luminaires can inactivate airborne pathogens in buildings, helping protect the health of occupants in schools, offices, health care facilities, and other shared environments. This webinar will highlight recent PNNL research demonstrating that GUV is among the most energy‑efficient and cost-effective air-cleaning approaches available. We will also share findings from evaluations of real‑world GUV installations, drawing on in-situ measurements to assess system effectiveness, safety, and occupant feedback.

PNNL: Distributed Spectral Sensors in Action: Accelerating Commissioning and Verification
PNNL researchers deployed more than 30 distributed spectral sensors at a federal building in downtown Chicago. The sensors record the SPD every 3 minutes, resulting in over 100,000 data points daily. Research objectives include characterizing the amount of light in the vertical plane throughout the day, how different circadian metrics vary throughout the day, the pros and cons of distributed sensors, and understanding if the sensors can speed commissioning of lighting systems designed to meet circadian recommendations.

PNNL: A Brief Introduction to NEMA/ANSI C137 – Automated Fault Detection for Indoor Networked Lighting Control Systems
This session will introduce attendees to a new industry consensus approach to describing common lighting system faults that is being developed by the NEMA-managed ANSI C137 – Lighting Systems committee. This common approach supports interoperability among emerging automated fault detection tools for lighting systems. A brief background on automated methods for fault detection, diagnostics, and maintenance actions will be presented, along with the current scope and status of NEMA/ANSI C137.13.

PNNL: An Analysis of the Advanced Functionality and Value Provided by Lighting System Integrations
This session will provide an analysis of 12 lighting system integration use cases, with a focus on how the integration improves the functionality and value of the lighting and/or other systems, and the interoperability challenges that must be addressed to facilitate integration. A deeper dive into the top 2-3 opportunities revealed by the analysis will be presented, along with a review of industry stakeholder feedback.

PNNL: The Growing Body of Research on Near Infrared and How it Could Change Lighting Practice
The “circadian era” of lighting has challenged lighting specifiers to expand beyond vision and aesthetics to account for how light can affect physiological wellbeing. Now the industry is beginning to learn that wellbeing isn’t just influenced by blue light, but also far red and near infrared (NIR) radiation. New products, bold claims, and nascent science offer an intriguing story of how an NIR-rich spectrum like sunlight could improve cognition, boost mood, reduce pain, repair tissue, and more. This presentation will introduce the science of photobiomodulation, outlining what is currently known and what could change in the future. It will also cover how lighting practice might change, and what to watch for as the science emerges.
