Certified Energy Managers (CEM)
ABOUT THE SEMINAR
This special in-depth five-day seminar is ideal for professionals who seek a more detailed program of instruction covering the technical, economic and regulatory aspects of effective energy management. The program provides detailed coverage of all of the six training areas specified for energy managers in the Energy Policy Act, and offers a comprehensive learning and problem-solving forum for those who want a broader understanding of the latest energy cost reduction techniques and strategies.
The CEM certification process requires the submitting of a separate application and $200 application fee, which qualifies you to sit for the exam. The CEM examination is administered on day 5 of each seminar -- only to those candidates who have met the above requirements. To obtain/print your CEM application form or see further information on the CEM program, visit www.aeecenter.org/certification/cem.
