Executive Committee
Russell Pope

Panasonic Life Solutions

Russell Pope is the Industry Development Manager for Panasonic Life Solutions, North America. Russell has over 14 years of experience in the residential ventilation industry and genuinely enjoys his job with Panasonic and the opportunities it provides. Russell serves on the Board of Directors for the Home Ventilating Institute, is an active participant in ASHRAE 62.2, ENERGY STAR, Department of Energy Programs, and Codes and Standards development.

Russell was born and raised in Florida and Jacksonville is home base when not traveling for business. As a graduate of Georgia Southern University with a degree in Industrial Management, he likes to believe that he is pretty well rounded with experience in manufacturing, sales, product development, and training, but he does not claim to be an expert in any of these categories (his 2 teenage sons strongly agree that “he is no expert….!”). I guess you could say that he is clever enough to realize that he is neither smart enough nor does he have the time to be an island. Together, Everyone Achieves More.

Where Residential Ventilation used to be relatively simple when homes were leaky, it has become a rather complicated, yet extremely important consideration in high performance homes. Russell consistently challenges the status quo as we must to ensure evolution in our industry. If we don’t consider all aspects of a home as a system, we violate our obligation to our fellow humans and produce unhealthy homes. Let’s all work together toward benefits for society and our customers by creating Healthy Homes and Life Solutions.

Steve Byers
Berthoud, CO

I was raised in a military family, so: Colorado, Georgia, Virginia, Germany to name a few spots. After graduating from the Air Force Academy, I flew C-130’s for five years. Not knowing exactly what I wanted to do, I got out of the Air Force, married Wynne Maggi and moved to Atlanta where she was completing her PhD in Anthropology. This meant that I went to Pakistan with Wynne and performed important tasks like chopping wood and what not. After that, I got my start in energy at Southface Energy Institute, starting as an intern and working my way up to running field operations.

Returning to Colorado, I got started in earnest in the rating and building science world, leading me to my present position at EnergyLogic. Wynne and I have two lovely daughters and live in Berthoud, Wynne’s hometown and a great place to live. Having never truly had a hometown, I am dedicated to building a sustainable community in my adoptive hometown.

I have my Bachelor’s degree in Asian history from the Air Force Academy and an MPA from Georgia State University. Hiking, gardening, movies, reading and great beer are a few of my favorite things. I love to travel, see new things, meet new people and challenge myself whenever I can. I run, sometimes a long way and sometimes short but fast.

The greatest everyday thing about EnergyLogic is our tremendous team of dedicated, frightfully curious people. I am perpetually honored by their efforts. On a larger scale, I am eternally thankful that I spend my days serving a larger mission. We’re doing everything we can to work toward creating a more sustainable and just world. Even the odd bad day is made worthwhile by our deeper mission.
