Supply Ventilation for Homes: Mythbusting Side Effects

Corbett Lunsford

'Home Diagnosis' co-creator and building science trainer Corbett Lunsford has told many students that supply-only ventilation is dangerous for homes in cold climates- but is that scientifically proven? Watch performance testing that will demonstrate exactly what happens (or doesn't happen) when pressurizing a house with supply ventilation from outdoors.

Super Airtight House: Blower Door Test

Corbett Lunsford

Corbett and Grace and their family have built a house that has better control over air leakage than 99.999% of any house ever built, anywhere in the universe. Here's how they found out.

Proving the Airtightness and Insulation of the #TinyLab

Corbett Lunsford

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.

Tiny House Blower Door Test: #TinyLab Test Series #1

Corbett Lunsford

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.
