    #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.

    #6-2026 – Adam Berry on Colorado’s New State Wide Energy Code

    Adam Berry, Building Codes Advisor with the Colorado Energy Office spoke with me about Colorados path to its 3rd statewide code.  Following plumbing and electrical the state energy code is a significant step for a home rule state where building codes are normally adopted, amended, and enforced at a jurisdictional level.  In this case, through legislation Colorado has adopted a new Model Low Energy and Carbon Code (MLECC) which becomes the States mandatory minimum standard for new and renovated buildings after July 1, 2026. After that date, all cities and counties in Colorado must adopt the LECCwhenever they update any local building codes. Amendments to the adopted code are only allowed to make the code more efficient than the LECC. Currently the State has jurisdictions that have no codes, and are likely to stay that way, and jurisdictions that are currently adopting the 2021 or 2024 IECC before the July 2026 implementation date so they don’t have to adopt the LECC. There are also some jurisdictions moving straight to the LECC, so in reality it is currently all over the place with a plan to get unified over time.  The Low Energy and Carbon Code is Based on the 2024 IECC with amendments to prioritize energy efficiency, fuel neutrality, and pre-electrification or electric ready requirements, such as EV and PV readiness, to address affordability, lower utility bills, and reduce carbon emissions.

    #5- 2026 David Heslam Executive Director Earth Advantage

    David Heslam is the Executive Director of Earth Advantage. A nonprofit based in Portland Oregon that works to ensure the U.S. housing market recognizes the elements of a home that create climate risk and values the characteristics of a homes that provide climate solutions. David spent 15 years designing, building, and remodeling homes in Portland. His award-winning company, Coho Construction Services, became known as a local and national leader for adopting new technologies and striving for high levels of sustainability. As his company migrated to working on more existing homes, he helped found Earth Advantage and became their director, where he has become a national leader in the effort to develop and deploy energy labeling systems into the residential market. Home performance labeling system put data in the consumers hands helping them better understand what they are purchasing and the value of better performing homes.  As you will hear toward the end of your conversation, David and I went down a rabbit hole of if the IECC requires a builder to heat or cool a house because of its hyper focus on the building thermal envelope.  I was able to find on Section R325.8 Required heating of the IRC where there is a requirement to every dwelling unit is required to maintain a room temperature of not less than 68 degrees.  There is no requirement in the IRC for cooling of a home David Heslam on LinkedIn Earth Advantage The Green Building Registry Appraisals Will Look Very Different in the Near Future—AreYou Ready?

    #3-2026 Chris Laumer-Giddens LG2 Architects - Zero Air Leakage?

    Chris Laumer-Giddens works for his wife Jodi at LG2 Architects. They are both Architects, but Chris’s specific interest in applied building science and high performance has shifted their work from solely providing the architecture for a project to providing performance designs including water management, air tightness, HVAC, efficiency and more. This in turn has led Chris and LG2 to a more integrated construction oversight role in the projects that he works with.  LG2 is not a traditional design build firm, but rather an architectural firm that stays involved and gets their hands dirty in the day-to day construction details to ensure that their design is executed and that the house is performing.  Chris has a ton of knowledge and experience to share and is starting to do so through Instagram and YouTube So be sure to go to the show notes to learn more.

    #2-2026 Rachel Wagner is the Impact Driver at Just Housing

    In this conversation I introduce Rachel Wagner as the Impact Driver at Just Housing as that is the professional title she chose in her company, but we seem to have never specifically talked about what that meant to her in our conversation. Now reflecting I see that she is impacting the design and construction industry and driving it toward meaningful and sustaining change.   Rachel sought opportunities to learn from some of the best building science educators in the business, internalized the message and is now pushing it back out there through standardized and repeatable methodologies which better ensures cost effective performance. She is also focusing on empowering her community through education, and like many of her mentors, she is giving insights and information away so others can succeed in their construction projects.  Please check out all the available resources on the Just Housing website.  Thank you, Rachel, for your building science and sustainability passion and for this wonderful conversation.
