Corbett Lunsford built the world’s highest performance tiny house on wheels, but it’s not because he’s a great builder. He’s an idiot- just ask him. The reason he could create a home that feels perfectly comfortable, smells great, and sounds quiet all the time is that he’s learned to think about the physics of home performance, and measure it. And he wants to pass along what he’s learned so you never feel like you wasted money guessing- Proof Is Possible through the ‘magic’ of performance testing like infrared, blower door, and HVAC diagnostics.

Whether you’re planning home improvements, trying to solve a mystery house problem, or buying or building a home, you will learn a ton in this crash course from one of the world’s experts on the topic. Bring any and all questions about your particular home, and get your hands on high-tech testing tools!

IN THIS 2-HOUR WORKSHOP, YOU'LL LEARN TO:

• Explore your home through the lens of the #TinyLab (which housed 3 people and 2 cats on a 13k mile tour)
• Understand the physics of home performance, and predict problems before they happen
• Control the way your home feels, smells, and sounds using the latest technology and materials
• Ensure your home isn’t poisoning or endangering your family
• Make better investments in home upgrades

PODCAST #77: Matt Risinger on Building High Performance Homes

How to Master the Multi-family Blower Door Test

Hello Corbett,
A need to run a Blower Door test at a 3 house complex here in Greece. The houses are in the row, this means that normally I should have three Blower door devices, in order to measure the house in the middle. But I have only one Blower Door!
Additionally, I will need to hand over a written document (report), in order to certify the construction to the Passive House Institute. Do you have any suggestions?
Best and thanks in advance,
Stefanos

Hey Stefanos-
Great question! You do not, in fact, need multiple blower doors, because you actually want to include the unit-to-unit air leakage.  The measurement of all uncontrolled air leakage to outdoors and to other townhouses is a valuable one, and it should be the goal especially when building to Passive House (or PassivHaus) standards.  Watch this video for a visual explanation:

How to Test a Kitchen Exhaust Hood

Let's do building diagnostics! Watch me demonstrate the commissioning of a kitchen exhaust fan in a big new apartment building. Just because the label says it sucks air doesn't make it so. Proof Is Possible- ask for it. Using a Testo 417 large vane anemometer.
