A note about this course:

Marc Rosenbaum developed this course back in 2015 and hundreds of people have taken it. Around 2017 the demand for the course fell too low to justify Marc running additional instructor-led sessions.

So please be aware that while much of the course material is still relevant, it is no longer being updated. As a result we have lowered the price by more than half and made the course available as a 'self serve' course that is not supported by an instructor.

Satisfaction guarantee - If you aren't happy with this course for any reason, just let us know within 7 days of enrolling and we will provide a full refund.

Course Description:

Learn how to incorporate transformative energy upgrades in existing residential and commercial buildings up to 45,000 square feet.

Forget the theory. This course will fundamentally change the way you approach retrofit projects, while build your network of like minded professionals. Your practice will never be the same.
