See how Corbett teaches home performance to the uninitiated after having given this presentation 214 times across the U.S. on the Proof Is Possible Tour. Special thanks to the tool companies and all other sponsors of the upcoming TV series 'Home Diagnosis' who have invested in making home performance a mainstream topic:
Home performance articles and stories from the field with internationally respected building forensics guru Corbett Lunsford at the Building Performance Workshop. Hear new episodes of the Building Performance Podcast, see new videos from the Home Performance YouTube channel, and learn all about how diagnostic testing (more than an 'Energy Audit') can make home improvement and new home construction a proven process!

Corbett performs a blower door test on LG Squared Architecture's #OffGridHomestead. Will Chris's toolshed beat the record set by the #DryVault? Will Passive House standards be outperformed? Will Corbett remember to plug in all his hoses?
Join building diagnostics guru Corbett Lunsford as he tests the airtightness and insulation of the #TinyLab, the highest performance tiny house on wheels in the world. Using a Retrotec 5000 blower door, DM-32 smart gauge, and ThermApp infrared camera, he proves that the #TinyLab is truly a work of science and art at the same time.
Watch building forensics expert Corbett Lunsford demonstrate Total External Static Pressure testing and pressure drop testing for a residential furnace and air conditioner. Learn to diagnose pressure problems in supply and return ductwork, filters, evaporator coils, and duct sections in just a few minutes with a minimum of testing tools!
Building forensics guru Corbett Lunsford gets his fix for prototypes of the testing tools we all know and love in the collection of American Treasure Neil Moyer: the first duct tightness tester (or Duct Blaster) built by Gary Nelson, a handmade flow pan (or Exhaust Fan Flow Hood), and a DIY House of Pressure!
Watch as Corbett and Grace test their airsealing work on the Tiny Lab with a Retrotec blower door! They fire up the new Model 5000 fan and find that the house has approximately 160 CFM@50 of air leakage, which is 4.7 ACH50 and 0.14 CFM per sq. ft. of enclosure surface area- and that's with stupid tarps over the window holes! We're going to test again when the windows are in.
Thanks to Julie Tolliver of Energy Fitness for Homes for the idea, to Retrotec for making awesome equipment, to 475 High Performance Building Supply for supplying America with awesome airsealing kits, and to Hewlett-Packard for creating awesome video editing stations that we work on every day.
Grace and I have been trying to make a TV show about home performance testing for years- we've tried three times so far! This is how it works traditionally:
- You get a network executive to want to see you as a couple onscreen because they think you're quirky or weird or otherwise compelling in a I-can't-look-away kind of way
- You work with a production company and pay out of your own pocket to shoot a 'sizzle reel' that shows off the personality of the hosts
- You remind yourself and everyone else that your show is about SCIENCE, not about relationship drama and being quirky or weird
- They remind you that no one cares about the topic in reality TV
- You feel frustrated and you throw the whole idea in the garbage because you don't want to play their stupid game
So we've decided to make the show ourselves, without asking anyone's permission. We find that works best for us- whether self-publishing a book (Home Performance Diagnostics) or making a feature film (The Other One), it always seems to work perfectly when we don't have someone breathing down our neck to conform to 'the way things get done around here normally.' Here's the show that will actually make it onto mainstream television: HOME DIAGNOSIS.
In 2014, we pushed hard for a show called PRESCRIPTION HOME PERFORMANCE to get made, but it went exactly nowhere. We went to the national RealScreen Summit, a non-fiction television programming conference (yeah, I know!), met with all kinds of networks to pitch the idea, and finally had Science Channel interested until they finally said, "wait, we don't want to compete with HGTV." And that was that. But you can still see what the show was like here:
And way back in 2009, we worked with our friends and client Sandy Gordon to make OUR GREEN COMPANY, which resulted in all of us being told by the Discovery Green channel that 'green' was a fad. Look at these kids- so young, so fresh, and maybe clueless!
Stay tuned for developments on HOME DIAGNOSIS- at the very least, it'll show on PBS just like This Old House does, and at most, it'll be running 24 hours a day on every channel there is. Probably it'll be somewhere in between!
If you'd like to participate in the making of this show, please reach out to us about it!
Learn to quickly and easily check the accuracy of a flow hood (in this case, a TSI AccuBalance) using a duct tightness testing fan (in this case, a Retrotec DucTester 200). If your diagnostic equipment isn't giving you accurate readings, no amount of experience will save you!
Today we talk with Colin Genge, founder and CEO of Retrotec, about the history of air leakage testing, how the tests really work (and what they doesn't actually test), and using home performance diagnostic techniques for playing competitive poker.
