IES Webinar Series
Each month, the IES presents a live webinar on topics we believe will be beneficial to our membership and the public at large. We are excited to offer you this education oriented program where you can expand your knowledge about lighting and earn IES continuing education credits (CEUs). We hope that you will join us. Consult the listing below for upcoming webinars. For the benefit of our members, we also list our webinar schedule in IES NEWS that is distributed every other week to IES members. We look forward to your participation. If you have general questions about the webinars, please forward them to Tom Butters, Director of Education

To obtain IES CEUs you must be individually logged in for the duration of the webinar.
No credits are given to those who log in exclusively by phone.

Webinars are free for IES Members; Non-Members: $20

Solving LED Dimming Issues in Retrofit Projects

October 18th 12:00 PM ET
LEDs are the go to light source for the replacement of existing lamps and luminaires providing a significant reduction in energy and an extended lifespan. LEDs can fit any form factor, and are extremely malleable compared to what we’ve been using in the past. However, dimming LEDs require careful coordination of lamps, drivers and controls to ensure proper performance. The session walks through dimming expectations for LEDs vs. incandescent such as dimming floor, color temperature, and linearity; the most common problems with LED dimming such as power line noise and how to address them. Participants to this webinar are eligible for one (1) IES Continuing Education Unit (CEU).

Nathan ThurmanNathan Thurman is Senior Technical Trainer for the Building Control Systems (BCS) division at Legrand. Nathan has been working in the automation industry for more than 15 years. He is an experienced field engineer with a demonstrated history of design, programming, and commissioning of large scale commercial and residential electrical automation systems. At Legrand, he is responsible for developing training content as well as conducting and delivering training sessions throughout various customer channels for Legrand brands. Prior to his role as Senior Technical Trainer, he was a field engineer supporting Legrand brands and product lines Vantage Controls, QMotion, and Wattstopper.

Before coming to Legrand, he founded Honest Integration, consulting in home automation programming and design. He also worked at Paradigm Systems as a Sales and Technical Advisor.

He has a Bachelor of Science in Biology and Chemistry at Texas Lutheran University.

A New Measure of Color Discrimination

November 15th 12:00 PM ET
Color rendition is commonly considered within three conceptual frameworks; color fidelity (the rendition of objects such that they appear as they would under a familiar reference illuminant), color preference (the rendition of objects such that they appear pleasant, vivid, or flattering), and color discrimination (the ability to distinguish colors of slightly different hue when viewed simultaneously). Color discrimination has been studied less frequently than color fidelity or color preference, though it is no less important. This presentation will summarize the previous literature on color discrimination and discuss recent work in this area. A recently published study by the current speaker will be discussed, which dispels the conventional wisdom that gamut area is a predictive color discrimination metric. This presentation will detail a new measure of color discrimination, which shows strong predictive ability of experimental results. Participants to this webinar are eligible for one (1) IES Continuing Education Unit (CEU).

Tony EspositoTony Esposito graduated from Penn State University in 2016 with a PhD in Architectural Engineering and a minor in statistics. His dissertation explored human responses to various light spectra with strategically varied average fidelity, average gamut, and gamut shape. His research offers an improved method for predicting color discrimination, validation of several trends in color research, and a simplified method for the quantification and specification of gamut shape.
Tony has won the Robert J. Besal Scholarship four times, received EP funding to attend the IES and IALD annual conferences, and previously served as a graduate fellow on an education grant from the National Science Foundation. He has delivered several guest lectures on lighting fundamentals and design, and has lectured nationally and internationally on color science.

Tony currently serves as a voting member on the IES Color Committee, IES Educational Material Review Committee, and the IES Annual Conference Steering Committee. He currently works as an independent Lighting Quality Researcher.

ASHRAE 90.1 Lighting Model

December 13th 12:00 PM ET
The Illuminating Engineering Society is a co-sponsor of Standard 90.1 along with ASHRAE. ASHRAE published an addendum and responded to comments on the addendum related to Standard 90.1. The addendum will establish the lighting power density values for Standard 90.1-2019. The focus of the webinar will be how the lighting model works and the inputs and outputs of the model. Presenters on the webinar include IES members: Kelly Seeger (Lighting Subcommittee Chair), Marty Salzberg, and Michael Myer. Participants to this webinar are eligible for one (1) IES Continuing Education Unit (CEU). Participants to this webinar are eligible for one (1) IES Continuing Education Unit (CEU).

Marty SalzbergMarty Salzberg was an architectural lighting consultant for more than thirty years, designing mostly institutional projects such as performing arts centers, libraries, schools and hospitals, as well as large site projects. Her work was honored with multiple industry awards for design and energy efficiency. As a member of the IES, Marty has taught sections of the FoL class in NYC, has been a member of the Library Lighting Committee since 2003 and is currently the Chair. She is a Professional Member of the IALD, serving as the IALD representative to the ASHRAE/IES 90.1 code committee. Marty teaches NYC energy code at the Building Energy Exchange (BEEx) and teaches lighting design at NY School of Interior Design.

Michael MyerMichael Myer has worked for Pacific Northwest National Laboratory for more than 10 years. Michael primarily supports the Department of Energy in his work. Both regulatory and voluntary market transformation work is included in Michael’s portfolio. Within the regulatory field, Michael has supported Department of Energy’s Appliance Standards program as well as now the Building Energy Codes Program. On the market transformation side, Michael is technical lead for Department of Energy’s Better Building Alliances. Michael has experience with field demonstrations involving lighting and advanced controls. Michael has an M.S. in Lighting from Rensselaer Polytechnic Institute. Before joining the lab, Michael was an architectural lighting designer in New York.

Kelly SeegerKelly Seeger is Technical Policy Manager for Signify where she leads building codes and standards activities for North America, advising company business groups, market teams, and researchers on implications for products and systems from pre-development through installation. She serves as Lighting Subcommittee Chair of ASHRAE SSPC 90.1 and is also active in the development of CA T24 and IECC and is involved with key organizations relevant to building efficiency, green building standards & codes, energy rating and benchmarking, and smart buildings. Kelly has worked in lighting and energy efficiency in the U.S. for nearly twenty years; her experience includes lighting design and application, strategic planning, voice of customer and market analysis, presentation and training, and energy efficiency & transformative market consulting. She holds M.S. Lighting and B.S. Building Sciences degrees from Rensselaer Polytechnic Institute in New York.
