Once again, energy expert and engineer Marc Rosenbaum is preparing to teach a 10-week online course on how to design and build zero-net-energy homes. The course will begin on March 9, 2015.According to the online course description, “You’ll learn key pitfalls to avoid and get numerical guidelines on sizing peak heat loss, glazing amounts, and solar electric systems. You will walk away with a comprehensive understanding of all of the key components of a zero net energy home — envelope, systems, and renewable energy sources — and how they fit together that will empower you to confidently create your own designs. Successful students will complete a full design for a zero net energy home, including an energy model, and earn NESEA’s Zero Net Energy Homes Professional Certificate.”Sponsored by the Northeast Sustainable Energy Association (NESEA), the course costs $895.Marc Rosenbaum is a well-known energy consultant and the director of engineering at South Mountain Company on the island of Martha’s Vineyard in Massachusetts. He is the author of many Green Building Advisor articles, including Minisplit Heat Pumps and Zero-Net-Energy Homes and Practical Design Advice for Zero-Net-Energy Homes.More information on the online course is available here: Zero Net Energy Homes.
