TM-30, In 2018 and Beyond: Guidance for Improving Color Quality

About this Course

The IES offers a series of webinars that provide supplemental education to coincide with a recently revised or new IES Standard (Recommended Practice - RP, Technical Memorandum - TM, etc.). You can review this standard in the IES Webstore

Description: This presentation will cover updates to TM-30, and how ongoing research is providing knowledge that allows for improved color quality. It will discuss where TM-30 stands within the North American and international lighting communities and demonstrate new features that may be added over time (feedback welcome!). In general, the emphasis will be on translating science into practice, with a focus on specification and highlights of new products being designed using TM-30.

Learning Objectives:

By the end of this course learners will be able to...

1. Describe the history and evolution of color rendition measures. 
2. Understand the information within TM-30, including the calculation framework. 
3. Review key elements of TM-30 including Average Color Fidelity and Fidelity Index (Rf), Gamut Area and Gamut Index (Rg).  
4. Read Vector Graphics to determine color characteristics of a light source.

Michael Royer, PhD

Dr. Michael Royer is a senior engineer at the Pacific Northwest National Laboratory (PNNL), where he works on the Advanced Lighting Science and Technology Research program, sponsored by the U.S. Department of Energy. His primary research area is human factors in lighting. He conducts experiments to help refine metrics and specification guidance, with the ultimate goals of advancing lighting quality to improve building occupants’ satisfaction and increasing the use of energy efficient lighting technologies. Michael is co-chair of the Illuminating Engineering Society (IES) Vision Science committee and a member of the Color Committee. He also serves on the International Commission on Illumination (CIE)-U.S. National Executive Committee and other CIE technical committees. He is an associate editor for the journal Lighting Research & Technology. Prior to joining PNNL, Michael earned a Ph.D. in Architectural Engineering from Penn State University, receiving the 2013 Taylor Technical Talent Award from the IES for his published work, which focused on tuning optical radiation for visual and nonvisual effects.
