We’ve just released a new version Marc Rosenbaum’s renowned Deep Energy Retrofits Course. Instead of a scheduled session which happens once a year, this course is now offered as a self-study on demand course which students can begin anytime.

We’ve replaced hand-graded assignments with quizzes and self-study work, which in turn made it possible for us to lower the sales price over by over 60%. This drastically improves both cost and availability for this course for our students.

Once you enroll in the course you have up to one full year to complete the material and earn your certificate of completion and continuing education credits.

This is one of our top rated courses with a 9.5/10 average rating from students so we are excited to be able to continue offering it in this new format. You can also get a taste of Marc’s great teaching style with his free short course Deep Energy Retrofit Case Study.
