Online Training

This intensive, 36-hour training is delivered over two weeks via twelve 3-hour daily webinars. The training is synchronous – all sessions are live with a trainer, so that student interaction is high. Students learn how to use energy modeling software and the training includes daily quizzes and homework assignments.
