Building HVAC Science covers a broad array of topics in building science and HVAC diagnostics, as well as human comfort, health, and safety. Hosted by HVAC measurement and building performance expert Bill Spohn, this show will take a deep dive into all things that relate to buildings and people in the built environment.
EP48 Buildings & Health. An interview with Dr. Stephanie Taylor
“He who has health, has hope; and he who has hope, has everything.”
Bill was honored to welcome Dr. Stephanie Taylor to the podcast where she shares the fascinating story of her career path from medicine to architecture to crusading for better building health by bridging these professional silos.
He had a great time interviewing Stephanie, plumbing the depths of her knowledge and experience. We discuss many aspects of IAQ and focus in on the impact of humidity on human health.
A key takeaway is our discussion of the invisible impact of a building on one’s health.

EP47 Insights from ENCON: A Unique, Generational Mechanical Contractor
“The family is one of nature’s masterpieces.”
Bill is joined Marty and David Indursky, a father and son team that have built Encon, an award winning, NJ-based HVAC/building solutions company.
Hear how David has reinvigorated the company by implementing modern technology techniques after he took it over from his father who founded ENCON in 1968.
They share best practices and what sets ENCON apart.
We also hear about and what David envisions for the future of the industry.
You can follow Encon via their website, Instagram, LinkedIn, Facebook or YouTube.

EP46 A new refrigerant born from science and sweat with Peter Capuciati Founder of Bluon
“I grew up thinking that a research scientist was a natural thing to be.”
There’s physical science. And there’s a kind of science as to how the mind works and how people achieve their dreams.
Blend one-part plasma fusion physics with one-part commercial real estate and stir this in an open and creative mind and you have Peter Capuciati, the Chairman and Founder of Bluon and the guest of today’s podcast.
Starting in 2011, Peter has led the team at Bluon to develop a true solution for R-22 replacement. It’s called TdX-20 (R-458a), something unlike anything the HVACR world has ever seen.
It truly is an energy saving product, as they are demonstrating amp draw decreases of 10-20% and increases in capacity of 3-6%.
We love digging into the science of HVAC in this podcast, and Peter is the perfect tour guide for the challenging journey of creating a refrigerant chemistry that has been proven to perform in about 80% of R-22 systems. This is backed up by real-world testing on equipment, not just simulations
After an easy, free registration and testing process, techs can gain full access to the operating manuals of over 22,000 types of R-22 units as well as individual retrofit instructions and compatibility ratings for each unit.
Beyond all this, Bluon provides the training, know-how and demonstrates (sometimes in person) the skills necessary to successful do a successful conversion.
If this sounds like a commercial for Bluon, it sort of is, as we sell Bluon at TruTech Tools.
However, this is exactly the kind of product we love selling; smart, well supported and one that relieves a major pain point for our customers. Plus, it’s fun working with the energetic Ninja team at Bluon, or as Peter calls them the Analog Renaissance Cowboys.

EP45 Making Homes Perform better – HVAC tips with John Semmelhack
“The only think I have learnt over the years is that if you enjoy your work and put in best efforts it will show. If you follow this process, things work out. But if you go chasing a formula, success will elude you.”
While building his own house, John Semmelhack’s innate curiosity grew as he researched the best was to design and build a home.
This lead him to start his own business, Think Little.
The name of his business is deceptive as John is truly a big thinker, who acts in quiet ways to create comfortable, energy efficient and durable homes that have excellent indoor air quality.
Lend us your ears to learn how following simple, yet important processes lead to amazing results.
We discuss HVAC Air filtration and why and how to get super-inexpensive, extremely effective filtration
He employs test and measurement at every appropriate juncture as well as post work, continuous monitoring for IAQ, energy and comfort. These factors are easier to measure than ever before!
John also reviews aspects of running this type of business including the variety of services he has developed over the years.
John Semmelhack is the owner of Think Little (www.think-little.com) and co-owner of Comparetto Comfort Solutions, a pair of home performance consulting and contracting firms based in Charlottesville and Richmond, Virginia. Think Little specializes in building enclosure and mechanical system design and commissioning for single-family and multi-family Passive House and zero-net-energy homes in the mid-Atlantic. Comparetto Comfort Solutions focuses on high performance HVAC installations for new homes in the Charlottesville and Richmond markets, as well as home performance contracting to help meet clients’ comfort, indoor air quality, durability and energy efficiency goals.
EP44 What's new in Home Performance 2.0 with Nate Adams
“True genius lies not in doing the extraordinary things, but in doing ordinary things extraordinarily well.”
General Louis H. Wilson, Jr.
Building science principles are few and fairly straightforward; ordinary, perhaps.
HAM: A lot of it amounts to control the flow of Heat, Air and Moisture.
But, like so many things in this world, the devil is in the details.
Listen in as I chat with my good friend Nate Adams (a true genius) to get an update on his extraordinarily execution of ordinary measures in his new concept of Home Performance 2.0.
This is a follow up to Episode 36, where I interview two of the HP 2.0 practitioners, Neil Comparetto and Michael Housh.
Measurements (so near and dear to my heart) are at the core of what he and his HP 2.0 army are all about.
For a more complete overview, tune in to a recording of his recent webinar on HP 2.0: www.bit.ly/NATE-HP20
Nate’s book, The Home Comfort Book, is perfect for consumers or practitioners alike and can be found at TruTech Tools or on Amazon.

EP43 Radon 101 with Dick Kornbluth
May the forces of evil become confused on the way to your house.
Yep, Radon is force of evil.
But sneaky. It’s deadly over decades.
My good friend Dick Kornbluth joins me to unravel the intricacies of all aspects of Radon – a colorless, odorless, poisonous radioactive gas.
Dick explains how and where radon is formed, how it gets into the air we breathe and the health impact it has on us.
He reveals where the famous 4 picocuries per liter exposure amount comes from, underscoring that there is NO SAFE LEVEL.
The US EPA has a treasure trove of information on Radon at www.epa.gov/radon
Dick shares with us his extensive and practical experience in how radon gas moves through a structure, how it is measured and how Radon mitigation systems work along with a note about radon resistant construction.
Dick is very engaged in the home performance world, and believes an improved understanding of Radon is key part of the home performance goals of healthy, more durable and energy efficient homes and buildings.
You can reach Dick at Dick@DickKornbluth.com
TruTechTools carries a broad array of radon detectors.

Accessible yet highly interesting
As a professional in this field, I find this podcast to somehow very elegantly skirt the line between providing both accessibility and depth. It tends to be pretty single-family oriented, so sometimes I wish it ventured into multi family building more often, but I won’t dock any points for this given that this isn’t necessarily the podcast’s aim. Great resource to keep you relevant!
Y’all eDeal wt you ready to come go to w you know what y’all want
Grateful for guys like Bill and resources like this!
If you want the “mysteries” unfolded, check this podcast out. I’ll keep tuning in to get the best practices from this legend!
