BPI HEP Energy Auditor Review for Field and Written Exams 2-Day course is designed to refresh students on the topics covered by the BPI HEP Energy Auditor Field and Written Exams. This is a two-day lecture-lab review course. A short review of the field guide and standards will be presented in a classroom setting and then followed up with student participation in the lab. This is a review of the diagnostics and hands-on portions of the field exam. Students needing more than an overview and refresher of the diagnostics will want to contact CHP Energy Solutions for other training options including our 203 Energy Auditor two-week preparatory course.
