First Look: ANSI/IES Recommended Practice for the Calculation of Lighting Power Density Values in Energy Codes
Kelly Seeger, Signify and Michael Myer, Pacific Northwest National Laboratory
Tuesday, March 15, 202
4:00PM - 5:00PM
Location: Murray Hill
This webinar details the inputs, calculations, and assumptions necessary to create robust lighting power allowances for modern energy codes. Adhering to the principles and guidance in this document ensures that the proposed lighting power density (LPD) values provide the appropriate IES recommended light levels for the space and activity and consider good design practice protecting the quality of the lighted environment. Use of this methodology is advised to safeguard the ability of the occupant to complete the necessary visual tasks in addition to targeting the lowest responsible amount of power for lighting given current design practice and readily available technology.
- Recognize how real-world lighting designs were utilized to validate model inputs for office, healthcare, industry, and retail applications.
- Explain how the lumen method was applied to develop lighting power density allowances.
- Understand the criteria used to establish lighting power density values and how this can improve your ability to evaluate energy code addenda.
- Identify how lighting for aging and low vision populations is addressed in the development of lighting power density values.

Senior Researcher, Pacific Northwest National Laboratory
Michael Myer has been with Pacific Northwest National Laboratory for 14 years. PNNL is one of the U.S. Department of Energy national laboratories. Prior to joining PNNL, Michael worked as an architectural lighting designer in New York. Michael became an architectural lighting designer after completing his M.S. in Lighting from Rensselaer Polytechnic Institute and his B.A. in Theatre from Arizona State University. Since joining PNNL he has worked on a wide-ranging number of lighting projects. Michael splits his time across a variety of programs including Building Energy Codes and Federal Appliance Standards; Commercial Building Integration, and Advanced Lighting / solid-state lighting. These programs provide Michael with a cross-cutting point of view where he can borrow and share across the programs. Michael has been involved in many field evaluations and demonstrations. Besides work, Michael is a parent and husband. When not working, he can often be found dealing with yard work or having fun with his family.
