This memo documents the analysis of the Northwest Energy Efficiency Council Building Operator Certification (BOC) program dataset as of 2015. The goal of this effort, conducted each year as part of the BOC evaluation, is to describe the 2015 new BOC certificants and update the count of active BOC certificants in the Northwest region (Idaho, Montana, Oregon, and Washington). Active certificants are those individuals who have received or renewed the BOC credential since 2010 and are the individuals for whom the Northwest Energy Efficiency Alliance counts energy savings for 2015. The results of the analysis find 228 new 2015 certifications and 115 certificants whose savings retired in 2015. In all, BOC has certified 2,796 individuals, of whom 1,568 are currently active.
