The evaluation teams assess the level of satisfaction with the training program from the perspective of students and key stakeholders like employers and utilities.
BOC Energy Savings Summary and FAQ (PDF 350k) The Building Operator Certification (BOC®) program has consistently produced positive documented energy savings and has proved to be cost effective. Since 2000, a number of BOC program sponsors have engaged independent third-party evaluators to assess and document the BOC’s energy savings impacts. This factsheet (FAQ) summarizes the electricity and fossil fuel savings from the studies published in this body of work. With increased reliance on energy efficiency as a resource and more utilities claiming energy savings for their BOC programs, the energy savings continue to be rigorously scrutinized.

BOC-Expansion Initiative Market Progress Evaluation Report #2 (PDF 822k) February 2015 – This is the second Market Progress Evaluation Report (MPER) of the Building Operator Certification Expansion (BOC-E) Initiative. The report concludes that BOC-E is progressing toward its goals, especially those supporting expanded outreach to large employers and utility sponsors, market penetration, and energy savings from certified operators. Market penetration in the 4-state Northwest region is 18% which suggests opportunity for further expansion. Non-credentialed building operators are interested in BOC but employer support is critical. BOC certificants, compared to a control group of non-certificants, are saving energy for their companies to the tune of 2% of electricity use and 3.5% of natural gas use. Finally, five regional utilities recommend or require BOC certification as a criterion for participation in energy efficiency programs.
Focus on Energy MEEA Training Program Evaluation (PDF 703k) January 2015 – This report summarizes the findings from a process and impact evaluation study conducted with Wisconsin building operators participating in BOC training in the period 2011-14. The evaluation showed high participant satisfaction with the courses and presents details on factors that led participants to take the trainings. Additionally, the evaluation assessed savings for the retrofit activities using the Wisconsin Technical Reference Manual (TRM) and other common industry sources for energy consumption data by building type and end use. The BOC savings reflect the energy savings from projects training participants completed after their training course, excluding projects rebated by Wisconsin Focus on Energy programs. The report identifies savings metrics per participant of 84,900 kWh/year for electricity and 36 therms/year for natural gas.
BOC-Expansion Initiative Market Progress Evaluation Report #1 (PDF 2.6MB) April 2014 – This is the first Market Progress Evaluation Report (MPER) of the Building Operator Certification Expansion (BOC-E) Initiative. The report concludes that BOC-E is progressing toward its goals, especially those supporting expanded outreach. To reach Federal employees, NEEC/BOC has taken actions to become a U.S. General Services Administration (GSA) training provider and continues to seek American National Standards Institute (ANSI) accreditation. The number of active BOC certificants is growing, but the operator market is larger, and thus BOC penetration is lower than previously assumed. Between 2011 and 2012, the Northwest experienced a net gain of 98 active BOC certificants (those who received or renewed certification within the previous five years). However, previous research underestimated total market size because it overestimated the mean facility square footage per operator. We estimate the total NW market to be about 10,000 building operators. With about 2,000 currently employed BOC operators, market penetration is about 20%.
The survey found that certain categories of operations staff are relatively more common among certain employer types: custodial staff in K-12 schools, management staff in colleges, professional staff in health care and property management firms, and general technical/mechanical staff in government and municipally owned facilities. This finding suggests multiple market sub-sectors, which may have implications for marketing, outreach, recruitment, and/or course planning. BOC-attributed savings comprise approximately 2% of electricity use, 1.8% of fossil fuel use, or 1.9% of BTU consumption from both electricity and fossil fuels. Certification-related savings may persist beyond five years. We found no evidence that savings percentages decreased after certification had lapsed five or more years, suggesting possible persistence of savings beyond the currently assumed five-year measure life. However, low statistical power prevents drawing firm conclusions.
Impact Evaluation of the California Statewide Building Operator Certification Program (PDF 2.6MB) Feb. 2014 – This report presents findings from an impact evaluation of the 2010-2012 statewide Building Operator Certification (BOC) program, which is a series of classes on various energy-saving equipment, measures and operations for building operators and/or facilities personnel. The program is funded by California Investor-Owned Utilities (IOUs) and administered by the Northwest Energy Efficiency Council (NEEC). The study was prepared by Opinion Dynamics Corporation under contract with Itron Inc. and California Public Utilities Commission. This study sought to better understand the energy saving potential and whether there are methods that would allow for a higher level of rigor when estimating energy savings from training programs. The study was conducted by means of a multi-step process built on existing program databases, course information, participant surveys and on-site visits. The study explored gross savings, attribution issues and double-counting with resource programs. Results indicate that performing on-site verifications in addition to surveys, allow for more accurate and comprehensive collection of data. The study also highlights the growing trend of low response rates to these types of studies and how that can impact the certainty of energy savings.
Impact and Process Evaluation of NorthWestern Energy 2007–2011 DSM Programs (BOC Chapter) (PDF 1.2MB) This report presents the methodology, findings and recommendations based on an impact and process evaluation of the NorthWestern Energy (NWE) Demand Side Management (DSM)portfolio, including Building Operator Certification, BOC. The conclusions that were reached from the process evaluation of this program were that energy savings for each year were reflected at a rate of UES values of 0.24 kWh/ft2 and 0.0013 dkt/ft2. Eighty percent of respondents reported that no area of the course needed to be improved. Nearly all (29 of 30) surveyed trainees reported that they would recommend the BOC trainingto their colleagues. Almost all surveyed trainees (28 of 30) indicated that they had applied the concepts or methods from the training at their facilities or shared the concepts with their coworkers (29 of 30) and most trainees reported that their facilities had started or completed at least one project aimed at increasing energy efficiency since they received the training. Recommendations for the BOC program from this evaluation were to consider ways to increase the use of internet tools to facilitate participation and to develop written program and process plans to improve consistency of objectives/ goals and strategies / tactics for the BOC.

Program Year 3 DCEO Building Operator Certification (BOC) Program Evaluation, May 2012 (PDF 1.3 MB) In this report to the Illinois Department of Commerce and Economic Opportunity (DCEO), an outside consulting firm, Navigant Consulting, examined the key findings that validate the benefits of completing the Building Operator Certification training course by analyzing and modeling student feedback. They found that net savings were 181 MWh and 37 kW per BOC participant. In depth detail about savings per participant, per square foot, and by various energy measures can be found in the report in Table E-2. Participant satisfaction with the course is very high- no respondent provided either the lowest rating of “fair” in the final course evaluations or the lowest ratings of “somewhat satisfied” or “not at all satisfied” in the participant telephone survey. Consistent with a high satisfaction rating, 81% of all participants surveyed responded that they had already recommended the BOC training program to colleagues. Feedback regarding the course approach was positive overall, while the study did outline several areas of opportunity to meet enrollees scheduling and logistics needs. Students enrolled in the program also had high remarks for the program instructors and marketing.
Northwest Energy Efficiency Alliance (NEEA) Long-Term Monitoring and Tracking Report on 2011 Activities, July 2012 (PDF 2.5 MB) In this report, Navigant Consulting examined the post-funding market effects of five initiatives: Verdiem, Residential Windows, Drive Power, Building Operator Certification and Commissioning. Per the logic of most market transformation efforts, the bulk of any energy savings tends to occur in these post-funding periods. Navigant estimates these projects have yielded an incremental 6.6 aMW in 2011 with the most significant savings associated with Commissioning (2.4 aMW), followed by Building Operator Certification (2.0 aMW). Drive Power reports 1.4 aMW in incremental savings, while Residential Windows resulted in 0.8 aMW. Verdiem showed 0.02 aMW in incremental energy savings.
