Early on in my carrier when working for a regional production builder, the president and owner suggested that indoor air quality was that path forward to communicate the benefits of applied building science, resilient, and energy efficient construction. I think he was right, but it still has taken living through covid to get the consumer to understand its importance to health in our homes.  Version 2 of the Indoor airPLUS program, which has just been released, will help us better understand the complexities of indoor air quality while pointing to relatively simple things we can do to ensure we build for better air quality.  It’s more than ventilation and filtration, it’s the fundamentals of applied building science and systems thinking, packaged in such a way that builders can truly market the benefits.

Nick Hurst is a renaissance man who, as you will hear, has been able to incorporate his love of music with his work in applied building science. He comes from the construction industry but has changed his focus from being a contractor and educator to being the EPA’s program manager for the Indoor airPLUS program. After learning more about Nick’s path to the EPA we hunker down and work our way through this newly released program.  I must note up front that although we accurately reflect the direction of version 2 of the IAP the discussion reflects the opinions of Nick and myself and not necessarily those of the EPA.

Stephen Davis is the product manager and director of building science for Quadrant Performance Materials. Quadrant is a spray foam insulation manufacturer that produces the EnvironSeal line of spray foam. Stephen has been working in the industry for the past 25 years and has always offered himself as a resource for all questions regarding spray foam, from building science to manufacturing and installation. I decided to take him up on his offer and it was wonderful to catch up, learn more about him, and to ask more questions about spray foam insulations in general.

I was able to speak with Dave Roberts just before he retired from the National Renewable Energy Lab after a full carrier leading a group of talented engineers and scientists who have been leveraging computer modeling and simulation to address pressing residential building efficiency, electrification, and carbon related issues in our country.

I first met Dave when he worked in software development with REMRate which at the time was the most widely used energy modeling software developed to create the RESNET HERS Energy Rating Index. He has been heavily involved with RESENT over the years as a member of the ANSI standards development committee and chair of the software calculations subcommittee.  We have become friends, and I wanted to be sure to speak with him on the buildCAST before his retirement to be able to better understand his carrier and catalog is contribution to our industry. 

Unfortunately, my side of the conversation did not record well and sounds a bit rough, but luckily for you Dave did most of the talking and he is well worth listening to. What he has to say puts a lot of our applied building science and other work with residential buildings into better context and he leaves a research question on the table for us to aspire to answer, hopefully in the near future.

Thanks, Dave, for all you have done, and I truly hope you have a wonderful and fruitful next stage of life.  All the best.

We get an overview of that history through his carrier and then learn about the important work Eric is aiming to accomplish with his newly minted consulting firm.  Home

 I have known Eric throughout my carrier as it also shadowed the growth and direction of Building America, EnergyStar, Indoor airPLUS, and the DOE Zero Energy Ready Home programs so it was a real pleasure to learn more of the inside story and history of these programs that have been so impactful in the building industry.

Peter Yost is the principle of Building Wright, an applied building science consulting firm based in New Hampshire. Peter is the person you turn to if you want to truly understand how buildings work and is one of those people you keep track of all your carrier. To be honest I was a bit nervous about this conversation, but quickly learned that Peter is not only an expert in the field of applied building science, but humble and human as well. Although coming from a building background, Peter appears to have stumbled into a concentration in applied building science in much the same way that I have, which may be part of the reason I respect him so much and view him as a mentor from afar. Pasion for the field, continued curiosity, and the ability to say “I don’t know but I can and will find out” are two of the traits I most admire in Peter’s professionalism and hope that I can emulate in my professional interactions. Thanks for a wonderful conversation, Peter, one that I know you, the listener of the buildCAST, will enjoy listening as well.

Eric Kaiser is the Industry Engagement Manager for TruTech Tools, which means that he is the conduit between the HVAC and home performance testing and commissioning industry keeping the pulse of their needs. As a former HVAC contractor Eric has learned the importance of commissioning and testing and its role in informing technicians about the performance of the products they are installing. Once again it goes back to is it there and does it work as it was installed. Eric has also become an educator and is committed to helping his clients understand building science, HVAC sizing, and performance-based data analysis. It was fun to learn the circuitous route Eric took to get to where he is today and to see the great work, he is doing to ensure that beyond the state-of-the-art tools TruTech is bringing to the industry, his clients know how, when, and where to use them to bring data to performance.

Ben Bogie is a Principal at Building Performance Cooperative, an employe owned building company specializing in building high performance homes based out of Ridgefield Connecticut.  As you will hear, he is a third-generation high performance builder who has incorporated what his father and grandfather were doing into our modern construction practices. Ben remains curious about green high-performance buildings, while delving deep into the building science that surrounds it. In addition, he is passionate, yet not a high-performance zealot, who believes there is only one way to build. Rational thought, healthy skepticism, and sound confidence in his professionalism allows Ben to be one of the leaders that is bringing applied building science to mainstream construction.

Joe Medosch is the Director of training and all things knowledge-based for Measure Quick, an HVAC commissioning tool that helps guide HVAC technicians to ensure the system they install, and work, on perform. In conjunction with a properly sized and designed system, Measure Quick uses measurements of air flow, refrigerant charge, temperatures, and static pressure to leverage data and therefore performance of installed systems. Growing from visionaries in the field like John Proctor’s CheckMe system, Jim Bergman, who created Measure Quick,

The disappointing fact is that the majority of installed residential HVAC systems do not get commissioned, which brings me back to Joe Medosch, who is a fanatic
