Lifetime Achievement Awarded to Ralph Prahl at the 2015 IEPEC Conference

Every two years IEPEC gives a lifetime achievement award to one (or two) deserving individuals. Nominations are provided from the evaluation community. The winner is selected by the IEPEC Board and Planning Committee.

This year, IEPEC is honoring Ralph Prahl of Ralph Prahl and Associates with the 2015 Lifetime Achievement Award. In receiving this award, Ralph is now

recognized as a member of an elite and prestigious group of professional evaluators. As quoted in the submission form:

“More than any other individual in the field, Ralph is responsible for and identified with the concepts of market transformation and market effects.” They point the multiple publications he has co-authored, starting in 1992 with “Are Markets Being Transformed by DSM Programs” and continuing to 2014 with Guidance on Designing and Implementing Energy Efficiency Market Transformation Initiatives.”

His development of the concepts, his clear explication of them, and his central role in operationalizing them in research and program design by themselves merit receipt of this award as is noted in the comments below.

“Few, if any, in the industry can match his understanding of both the big issues, as well as the detailed intricacies of impact, process, and market evaluations across the commercial/industrial and residential sectors and across the full range of technologies and markets. Those who have worked with him are amazed at the number of documents he is able to review carefully and critically, and the number of conference calls he is able to engage in thoughtfully. It is no exaggeration to say that, through his role as reviewer, Ralph Prahl has elevated the quality and incisiveness of evaluations throughout the industry.”
