Les Nelson was involved with NABCEP from nearly the start of the organization and served as Treasurer for the majority of his time on the NABCEP Board of Directors, which spanned almost 20 years. Les came to NABCEP with extensive experience in the solar heating industry and had been involved in solar thermal manufacturing, regulatory and policy development, and solar energy advocacy at the state and federal levels since 1972. His passion for solar heating and level-headed approach to doing business showed through in many ways over the years.
Les was instrumental in incorporating additional hydronics code language and the new sections of geothermal into the Uniform Solar Energy Code, making it the Uniform Solar, Hydronics and Geothermal Code it is today. He was working on projects related to the increased electrification of hydronic systems. As the executive director of the Radiant Professionals Alliance and staff liaison to the Hydronics Industry Alliance – Commercial (HIA-C), Les was able to gain increased cooperation within the industry. He was skilled at keeping the teams focused in order to maintain and grow these industry segments. He authored several technical journal articles and was interviewed numerous times by industry press for his expertise. He also worked closely with BNP Media’s Plumbing Group to produce the biannual Radiant Comfort Report.
Along with serving as a Board member at NABCEP, Les was previously a director of the Solar Energy Industries Association (SEIA) and chair of its Solar Heating & Cooling Division, a director of the California Solar Energy Industries Association (CAL SEIA), and a Vice President of Advanced Energy Programs and RPA Executive Director, IAPMO. He also served as operating agent for the International Energy Agency Solar Heating and Cooling Program’s Task 43: Solar Rating and Certification Harmonization.
Les will be dearly missed by all who knew him!
