  • NATURE INSIDE: Productivity, BIOPHILIA, & Lighting Bill Browning
    • Bill will discuss physiological and economic implications of improved indoor lighting. He will also introduce a recent study exploring the effect of biophilic design interventions on student stress and academic success, and will explain how the study's structure can inform future lighting research. Lastly, Bill will show a few case studies illustrating how designers are using scientific insights to improve the indoor experience.
  • Measuring Impact Ron Gibbons
    • This talk will highlight methods and approaches to measuring the impact of lighting in the exterior environment. How light impacts drivers and pedestrians, and some of the new approaches to consider in lighting design with the advent of solid state lighting, will be discussed.
  • Specifying light source color rendition Tony Esposito
    • This session will describe the current state of lighting metrics for the specification of light source color rendition with particular focus on the description, computation, application, and translation of IES TM-30 metrics and TM-30 ANNEX E color rendition specification categories. The session will close with a look into the future of color science research, with specific emphasis on metrics and aspects of color rendition not covered within the IES TM-30 framework.
  • Evidence-Based Interactions between Indoor Environmental Factors and Their Effects Clarence Waters and Michael Kuhlenengel
    • We will speak about a recently completed project entitled “Evidence-Based Interactions between Indoor Environmental Factors and Their Effects on K-12 Student Achievement”. The study, funded by the Environmental Protection Agency (EPA), measured lighting (both daylight and electric), acoustical, thermal, and indoor air quality characteristics of 220 classrooms in five school districts and compared them to student performance on standardized tests.

Bill Browning

Bill Browning is one of the green building and real estate industry’s foremost thinkers and strategists, and an advocate for sustainable design solutions at all levels of business, government, and civil society. His expertise has been sought out by organizations as diverse as Fortune 500 companies, leading universities, non-profit organizations, the US military, and foreign governments. He is passionate about the interactions between the built and natural environment, and how that supports health and wellbeing. In 2006, Mr. Browning founded a new firm, Terrapin Bright Green, to craft high-performance environmental strategies for corporations, governments, and large-scale real estate developments.

Ron Gibbons

Director of the Center for Infrastructure Based Safety Systems

Virginia Tech Transportation Institute

Ron Gibbons is the Director of the Center for Infrastructure Based Safety Systems (CIBSS) at the Virginia Tech Transportation Institute (VTTI). He is the Institute’s lead lighting research scientist. He is currently the PI on projects investigating the impact of outdoor lighting on human health, the Spectral Effects of new light sources on roadways, the visibility of police vehicles and is the subject matter lead for the FHWA office Safety IDIQ contract. Dr. Gibbons is also an Associate Professor in the School of Architecture and Design at Virginia Tech. Gibbons is the author of over 80 published papers on roadway lighting, photometry, and target visibility. He is a past Director of Division 4 of the International Commission on Illumination (CIE) and a past president of the Illuminating Engineering Society of North America.

Tony Esposito, PhD

Tony Esposito holds a doctorate in Architectural Engineering from Penn State University with a minor in statistics. His specialties include color science, color discrimination, human factors research methods, circadian metrics, and spectral modeling and optimization. His primary research goal is to develop an accurate and intuitive color discrimination metric for applied lighting.

Tony is a former graduate education fellow to the National Science Foundation, has won the Robert J. Besal Scholarship four times, is a recipient of the 2019 Richard Kelly Grant, and is a recipient of the 2019 Walsh Weston Award from The Society of Light and Lighting for the best fundamental lighting research paper published in Lighting Research and Technology. He currently serves as a voting member of the IES Color Committee, formerly lead the task group that developed IES TM-30 ANNEX E and F (recommended specification criteria using IES TM-30), and is the Founder and Head Research Scientist of Lighting Research Solutions LLC.

Dr. Clarence Waters

Dr. Clarence Waters is the Aaron Douglas Professor of Architectural Engineering (AE) in the Durham School of Architectural Engineering and Construction at the University of Nebraska-Lincoln. Dr. Waters has a Ph.D. in AE from Pennsylvania State University (1993). His B. S. (1978) and M.S. degrees (1988) are in AE from Kansas State University. Dr. Waters has been on the faculty of the University of Nebraska-Lincoln since 2000. Dr. Waters served on the faculty of Kansas State University in AE from 1986 to 2000. He was the head of the Department of Architectural Engineering and Construction Science at KSU for four years. He served as a Research Associate at the National Renewable Energy Laboratory (NREL) Golden, Colorado, (2011 - 2012). Prior to his academic career, Dr. Waters served for over seven years as an electrical project engineer for Professional Engineering Consultants in Wichita, Kansas.

Michael Kuhlenengel

Michael Kuhlenengel is a fourth year PhD student at the University of Nebraska - Lincoln in Architectural Engineering. He has spent the last five years working on a EPA funded research grant titled School Environmental Effects on Student Achievement. The EPA project studies the lighting, mechanical, and acoustics of classrooms on student achievement. His primary focus for the EPA project has been on lighting and statistical analysis. Michael has presented parts of this research at the 2016 IES conference, 2017 AEI conference, and the 2019 CISBAT conference. He is currently working to finish his PhD and journal articles for the EPA project.
