This course was an efficient and practical way to learn the ins and outs of how to conduct a deep energy retrofit on a building. The world be a much better place if every contractor and builder learned and applied the material in this course!

This course will help in everyday analysis of building envelopes when it comes to new construction and in retro work. I believe it clears up or verifies preconception of how a structure leaks and retains heat. Specific attention is always on health and safety and moisture cause and effect.

I really enjoyed this course! It is a great introduction to building science and residential construction techniques, with the focus being on energy reduction and savings. Marc speaks clearly and doesn't not delve too deeply into technical details or calculations, which allows for a well-established understanding of the topics at a high level.

Marc's approach to deep energy retrofits is technically astute, pragmatic, and replete with a broad range of real world case studies. I completed this course understanding far more about DERs than I'd ever imagined.

This is the second course that I've taken with Marc (I'd taken his Zero Net Energy Homes course previously), and the superlative quality of Marc's instruction and assembled materials were entirely consistent with his ZNE course. I highly recommend Marc's courses.

This is the second course of his that I have taken, that should tell you something. Marc is on the cutting edge of Net Zero and DER design. He covers all aspects that are needed for a complete design of the technical engineering aspects.
