Description

Developed in partnership with the Energy and Environmental Building Alliance (EEBA) and TEAM ZERO

Master a comprehensive understanding of all of the key components of a zero net energy building—envelope, systems, and renewable energy sources—and how they fit together to confidently create your own designs. During the course, you’ll learn key pitfalls to avoid and get numerical guidelines on sizing peak heat loss, glazing amounts, and solar electric systems.

Marc Rosenbaum, your instructor, is one of the most popular and best-reviewed speakers at NESEA's BuildingEnergy conference every year. He’s an engaging speaker, extremely honest, meticulously detailed, and curious by nature.

"After teaching over 300 participants, I’m convinced self-paced, asynchronous online learning is the way to master and apply new skills and knowledge." —Marc Rosenbaum

You'll need to have Microsoft Excel and some basic excel skills in order to take full advantage of the course and the included Excel calculators and tools. The course includes several tools and calculators developed by Marc over his years designing Zero Net Energy Buildings and are invaluable for professionals in the industry designing and developing ZNEB.

Important: Minimum Of 10 Students Required To Run This Session
We require a minimum of 10 students in order for Marc to host an instructor-led portion of the course. In the event that the instructor-led portion is rescheduled students can either join the next session or continue to access the materials as a self-serve course.

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 [...] Marc Rosenbaum is a natural educator. I highly recommend this course to anyone who values energy efficiency in buildings.

- Jamie Fereday, Sol Coast Consulting and Design

Thanks for putting together a great course, Marc. I've been studying building science regularly for several years now, and I really appreciate how comprehensive your course is and how well it integrates the material.

- Bruce Dichter, Living Homes, Inc.

For those of you looking for a solid foundation in how buildings work and how to design them well, I cannot recommend Marc's offerings enough.

- Jacob Deva Racusin, New Frameworks Natural Building

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

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 [and] materials Marc offers in this course are indispensable to anyone in the trade. I highly recommend it!
