Brian Shanks is the Manager of National Accounts and Governmental Affairs for Beazer Homes.  Beazer is a production home building company based in Atlanta, Georgia. The company is the 11th largest homebuilder in the United States and now operates in 13 states.

Brian’s construction career has been aligned with energy-efficient and performance building in the world of large production builders, and now he is part of the team at Beezer Homes that is continuing the home builder’s evolution from building 100% EnergyStar home to committing to build and certify DOE Zero Energy Ready Homes. 

When they had a presence in Colorado, my former companies did all the energy code and EnergyStar compliance work for Beezer Homes, so it was particularly interesting for me to learn more about Beazer’s continued efforts to build high performance homes in the production building arena. 

Thank you, Brian, for sharing your building journey with us and for explaining some of the unique issues that production builders face.

Lisa Morey is a professional engineer and architectural designer who starting building with adobe bricks while living and working in New Zealand in the early 2000’s. While there she worked with a design/build firm that constructed nearly 50 earth block homes that was the catalyst for her company Colorado Earth.  Lisa is now a champion for earth block construction, not only how to make the earthen block and build the house, but also to understand how the science of thermal mass works. Lisa continually demonstrates the efficiency, resiliency, and carbon neutrality that can be gainusing earthen blocks and was recently recognized as a woman making contributions to reduce carbon emissions within the building sector.

How did Sam Myers become the building scientist at Retrotec? Find out in this episode of the BUILDTank / buildCAST. Like most of us, the industry found Sam and a passion for building science blossomed. Unlike most of us Sam has created and grown his position in the industry on the back of his passion for finding unique ways of educating everyone that he comes in contact with. During the COVID most of the industry’s conferences and tradeshows moved to online platforms. To keep providing the industry with quality educational material, Sam built a virtual training lab athis home where he has taught and trained contractors and consultants all over the world. I enjoyed my conversation with Sam geeking out on building science and diagnostic testing and I think you will as well.

Thanks for listening to the buildCAST. In this episode we hear from Steve Baden, the founding Executive director of the Residential Energy Services Network or RESNET. RESNET is the governing body of the HERS home energy rating industry which was established in 1995 by the National Association of State Energy Officials, Energy Rated Homes of America, and the National Mortgage Industry Association to develop a national market for home energy rating systems and energy-efficient mortgages.  I was in the first energy Rater training and became the 32nd certified rater in Colorado in 1995.  Soon after I met Steve at the first RESNET conference held at the Florida Solar Energy Center when I was on the board of directors of Energy Rated Homes of Colorado.

Even before Jimmy Carter’s infamous, wear a sweater speech from the oval office Steve’s path to energy efficiency came though politics. He found himself in Alaska at the state energy office leading an initiative called “Warming Homes for Alaskans” which received the 1993 national award for the most outstanding state housing program, and which set the stage for a national home energy rating program that RESNET grew out of.

Steve has worked in the residential energy efficiency field for 30 years, including eighteen years with home energy ratings and energy mortgages on both the state and national levels, and ten years administering the Alaska State Energy Office. Steve is the founding executive director of RESNET and has just announced that he will be retiring on December 31st, 2025.  I have known Steve from the beginning of the founding of RESNET and my time as a board member of Energy Rated Homes of Colorado and was so happy to have the opportunity to recap his career on the buildCAST before his last day. 

Thanks for all you have done for the Industry Steve.

Thank you to Nicole Tysvaer Founder and CEO of Symbi Homes for being on the BUILDCast. Symbi Homes is a sustainable construction firm reinventing home building with an emphasis on wellness, energy-efficiency and technology. Symbi short for Symbiosis immediately got my thinking about building science, systems thinking, and the synergistic interactions that take place in construction of high performance homes. Symbi Homes has decided to follow the DOE Zero Energy Ready Home program specifications to guide their path to high performance building. Uniquely they have also chosen to apply these high-performance specifications to a Queen Ann Victorian complex form as well as in their current remodel and addition current project. To me this beautifully demonstrates that homes of all shapes and sizes can pursue high performance building when project goals are clearly defined from the start.

We dove quickly into the Water Efficiency Rating Sore or WERS system with Mike Collignon Executive Director & Co Founder of the Green Builder Coalition.  So quickly in fact that we did not have time to talk much about the other cool things the coalition is doing, so definitely check out their website in the show notes to find out how they are a uniting voice for sustainable home building especially for the custom builder community

In short, WERS is a performance-based water efficiency program for both new and existing residential properties. This approach to water efficiency preserves design freedom and product choice flexibility. Third-party analysis and data collection is utilized to generate both a score and predict water usage for single-family and multifamily properties. Especially here in the west and specifically in the southwest, more and more water utilities and jurisdictions are looking for ways to better manage water in the build environment so that builders can continue to meet our housing demand.

Starting in tech, moving into solar, Stephen Kane found his home at SPAN where he is helping builders integrate smart electric load management to lower the cost of electrifying homes while giving homeowner’s a better user experience.  Our conversation touched on both new construction and existing homes as the move toward electrification is touching both worlds.  I have to say that I found our existing home conversation particularly interesting since I am on a glid path to electrification of my own home. That being said, I see this technology helping manage not only operational cost, but also the cost of construction. We are now not beholden to installing huge capacity panels when our real life loads never, or rarely, match the code calculated electrical loads.

Rob Howard began his construction career with Habitat for Humanity where he built ENERGY STAR homes through Advanced Energy’s System Vision program. When he became director of construction at Habitat he built the first Net-Zero Energy Home in North Carolina in partnership with the Appalachian Energy Center in 2005. He now only builds DOE Zero Energy Ready Homes and was a 2024 Housing Innovations award recipient.

Uniquely and parallel to Rob’s building career is his career as an academic.  Rob holds a bachelor’s degree and a renewable energy technologies diploma from North Carolina State University and a master’s degree in sustainable technology and building science from Appalachian State University where he now serves as a full-time faculty member.

Rob’s practical and academic background made our conversation particularly fun as he was able to interweave his passion for building science into mainstream applications which, to me, helps better explain why everyone in the construction industry should embrace applied building science in the proustite of our modern everyday home.
