BPI / RESNET Dual Certification is made possible by Saturn Resource Management.  Saturn delivers online courses for energy professionals. Students may need to prepare for certification exams, expand their careers, fulfill job training requirements, or accumulate continuing education credits. Courses are enrollable up to one calendar week after the course's start date. Residential Energy and the Energy Auditor Field Guide are the supporting textbooks for most of our courses. Our Building Analyst and HERS Rater course is directed toward auditors who plan to take the BPI/Building Analyst Professional exam and/or the RESNET HERS Rater exam.
