Residential energy efficiency putting theories into practice part 2
As a follow up to his presentation at the 2019 Maine IAQ & Energy Conference, Bill Spohn gives an update on the journey of designing, building, and a modular-built high-performance home. You will learn the paths he went down (and back!) before arriving at the design (and features) he and his wife will enjoy as homeowners. A mix of technical and consumer topics are covered: - How can you apply as many "cutting-edge" techniques and systems without overwhelming your builder - What kind of compromises must be made to integrate with available techniques and experience - Did the design meet the goals? Bill is President and co-owner of TruTechTools.com, an award-winning reseller of tools and test instruments. He holds a BS & MS in Mechanical Engineering and is a Registered Professional Engineer (PE) in Pennsylvania. Over the last 30 years, Bill has built his career on creating, designing, and marketing a wide array of test and measurement products that work for technicians in the field. Bill is all about Science – Comfort, health, and energy efficiency. He has worked on BPI, RESNET, GAMA, AHRI, OMA, RSES, NATE, and ACCA Technical Committees, and holds four US patents in instrumentation design. He regularly consults, teaches, and writes on product applications in HVACR, building science, healthy homes, Indoor Air Quality, and weatherization. Bill is smart, a great listener, and speaks with passion and in a language we can all understand. He shares his knowledge in the two podcasts: Building HVAC Science and RESTalk. He and his wife built a modular, high-performance home near Pittsburgh, PA. Keep tabs on the details at www.SpohnHome.com

- Each panel is a monolithic pour using a consistent batch of 5000psi fiber reinforced concrete. A 5000psi concrete is used for strength and for watertight characteristics. The concrete mix exceeds watertight standards determined by the American Concrete Institute. Incorporated into the concrete are multiple layers of 1/2″ and 5/8″ steel reinforcing rods. Foundation panels weigh between 440 and 512 pounds per linear foot. Our insulated product consists of 8-1/2″ of EPS foam with an R-value exceeding R-30.
