This was one of the best learning endeavors with which I have been involved. The very complete building science content helped me better understand the concepts I thought I understood or was lacking altogether and reinforced those concepts I did understand. The discussion board format works better than a classroom setting, giving all the time to think and give relevant feedback, ask questions, and see all responses. We all get to look over the shoulders of classmates to see their work. I have been extremely impressed at the efforts of my classmates and strived to do my best in turn. Marc Rosenbaum is a natural educator. His feedback is always constructive, encouraging, thoughtful, and he adds whimsy and humor in the appropriate quantities. I highly recommend this course to anyone who values energy efficiency in buildings.

Designing the capstone project, getting it to the point where there are effective performance numbers and dimensioned drawings that allow for material take-offs for pricing, has been a fantastic learning experience.

- Daniel Haedrich, Back Tilt Studio

This is an outstanding class, bringing an enormous amount of material into an organized series of learning modules.

- Tim Van Meter, Van Meter Williams Pollack, LLP

I appreciate Marc's high level of involvement and attention to detail when reviewing and responding to homework assignments and questions. The lectures are informative and entertaining. I learned a lot from this course both technically through the material and professionally through observing Marc's teaching style.

- Margo Valdes, Conservation Services Group

This is a great course if you are a professional in the field or just a homeowner interested in decreasing your energy usage.

- Ann McKinley

Your worksheet creations are really a tremendous tool for a builder like myself. I have gained insights that I never knew existed and have never seen coming from design professionals.

- Bill Tornrose, Tornrose Williams Builders

Marc is a wonderful teacher and communicator. If the construction industry is going to change to high performance construction, we need to make sure certain key concepts become the new norm. Marc is clearly a forerunner in creating this new path. If he had an sequel to this course, I would take it.

- Valerie White, White Architects

Marc's course greatly expanded my understanding of energy use in buildings and the potential of super insulated, low energy homes. The tools, materials, and guidance Marc offers in this course are indispensable to anyone in the trade. I highly recommend it!
