    #15- 2026 -Carl Grimes Director of the Hayward Healthy Home Institute - Part 2

    Welcome back to Part Two of my conversation with Carl Grimes. Our conversation picks up where we left off explaining more of the five principles and then gets into how Environmental health is impacting the building of homes. Enjoy Hayward Score Healthy Home Director Carl Grimes, has a unique combination of experiences. He has personal experience of the disabling impact of an unhealthy home, and professional experience working in the Indoor Air Quality field. Both these experiences lead him to the Hayword Score where they are helping people live healthier lives by first believing in the negative health experiences they are having in their home, and second by offering a tool that can help homeowners understand these experiences. Carl understands that moisture and mold are not the only things that lead to poor indoor air quality and is trying to work out the synergistic interactions between occupants, house, and building science that can result in either a health supporting or health degrading environment.

    #13-2026 Ken Nelson and whole house controlled mechanical ventilation

    Ken Nelson is well known as an applied building science and indoor air quality (IAQ) expert at Panasonic North America. Our conversation wandered through the three ventilation strategies and further explained Panasonic’s Oasys System, which I really did not realize is an innovative approach for heating and cooling not just whole house ventilation. Ken is passionate about the subject and seamlessly explains the benefits for all stakeholders as well as some of the stumbling blocks we need to look out for during installation.

    #11-2026 Randy Plumlee and Jason Helm – What mechanical ventilation systems does the IECC require to be tested?

    Randy Plumlee specializes in energy code and building performance with SPEER or the South Central Partnership for Energy Efficiency as a Resource which is one of six regional Energy Efficiency Organizations. Jason Helm is the CEO for Texas Home Energy Professionals. In this conversation you will hear the three of us debate whether the International Energy Conservation Code requires both Whole House controlled mechanical ventilation and local, or spot, exhaust ventilation systems to be tested to achieve the flow rates required by the International Residential Code or IRC.  This is of special interest to me since I introduced the proposal in the 2021 IECC for this testing requirement and I definitely have a point of view. Randy and Jason do as well.  Let’s see what you think after listening to the conversation Randy Plumlee on LinkedIn SPEER Jason Helm on LinkedIn The Home Energy Rating Systems Council RESNET Home Certification Organizations (HCOs)Building Science Institute (BSI) John Krigger's Residential Energy

    #11-2026 Bill Rectanus – AUAR or Automated Architecture – Turning Every Job Site into a Factory

    Bill Rectanus spent the bulk of his career in the world of construction innovation. Seeking out materials and solutions to drive production building to zero energy while being cognizant of cost effectiveness and bottom-line economics. Working for midsize regional production builders in Colorado for the bulk of his career, Bill found his next chapter aligning with Automated Architectural. AUAR as the company is known, is a company from England that has the capability to turn a job site into a factory by deploying Micro-Factories to build wall, floor, and roof panels directly on the building sites where they will be installed.  This new phase of panelized construction has potential to address skilled labor shortages, as well as the economics of constructing homes that could be the next innovation that the construction industry is looking for.

    #10-2026 3rd Party Inspection with Rich Truitt Building official Harford County Maryland Part 2

    Welcome back to our buildCAST conversation with Rich Truitt, Harford County Maryland Deputy Code Official.  In this second half of our conversation we dive deep into the Approved Third-Party Inspection Agency section that has been expanded and better explained in the 2024 IECC. Through Rich’s experience we see again the good, the bad, the ugly, and the potential future of this relationship between jurisdictions and Approved Third-Party Inspection Agencies.

    #9-2026 Implementing the IECC with Rich Truitt Building official Harford County Maryland Part 1

    At the time of our conversation Rich Truitt worked for Harford County Maryland.  He is now with the Internation Code Council. Rich began his career in the code world as a plan reviewer with Harford County, became the Chief Building Inspector and then served as the Deputy code Official.  I met Rich through our mutual interest in the continual development of the International Energy Conservation Code, and our conversation is based on Approved Third Party Inspection Agencies and his experience working with third parties who are assisting with Energy code enforcement.  The good, the bad, and the ugly. Our conversation was long, so I broke it up into two parts.  Part one introduces Rich and defines the IECC as a stand-alone code vs. the energy code in chapter 11 of the IRC. We also speak to how code officials, architects, builders are currently understanding how to work within the energy code, and finally we speak to sections in chapter one that come before the Approved Third-Party Inspection Agency section which we speak to in Part two of our conversation.

    #8-2026 Don Worthington and the LOWTILITY Energy Efficient and Improvement Mortgages

    Unless you have your own company, most of us in the building industry have been laid off.  I was laid off in the early 1990’s and decided to start my own company rather than work for someone else.  Before getting laid off, however, I was exposed to blower door testing and energy modeling through a state of Colorado funded technical assistance program.  I then worked for that State program for a while before becoming a certified energy Rater and home inspector. My new business fully embraced the idea of being able to offer an Energy Improvement mortgage (EIM) to existing home buyers and an Energy efficient mortgage (EEM) for new construction home buyers. It became apparent very quickly that I would not be able to sustain and grow a business on the back of a mortgage product that realtors and mortgage lenders would not embrace so I pivoted with the industry writlarge to working primarily with builders. Energy related mortgages never fully died, and the golden grail has been, to figure out how to more directly adapted the mortgage Principal, Interest, Taxes, and Insurance equation (PITI) to include Energy (PITI+E) Fast forward 30 plus years and let me introduce you to Don Worthington, a mortgage lender with Primary Residential Mortgages who is specializing in bringing back the energy efficient mortgage (EEM) and the improvement mortgage (EIM) through the LOWTILITY mortgage product. LOWTILITY is a home loan designed around the true cost of home ownership that does not ignore operational cost, or the additional costs, that traditionally always occur, to make a newly acquired home livable and comfortable.
