Testing the World's Worst Duct System

Corbett Lunsford

I'd love to show you this, but my client has asked that I take this video down while they try to reconcile with the installer. Fingers crossed everybody, and sorry to be a tease.

Performance Testing with Obsessed Garage, Ep1-5

Corbett Lunsford

Corbett traveled from Atlanta to Orlando to help Matt Moreman of Obsessed Garage get all the spec's on his 4000 sq. ft. house. See the blower door setup, 3D modeling, kitchen exhaust hood pressure testing, and inspection of the home's exterior and attic in preparation for the Vitals Checkup package:

Next, we run the blower door depressurization and pressurization tests, and the beginnings of infrared thermography and zonal pressure testing across the house:

We continue going beyond the traditional 'energy audit' performance testing to create a prioritized map of home improvements to control comfort, moisture, air quality, energy efficiency and durability:

Time for home improvement conclusions and recommendations for Matt's family, including air sealing, duct sealing, and equalization of heat flow in rooms of the house:

As Matt plans for his future headquarters for Obsessed Garage, Corbett starts the energy consulting process for controlling all the invisible dynamics of the building: heat bleed, airflow and pressure, moisture, and air quality:

Testing Atlanta's #DryVault with Blower Door & Infrared Camera

Now that Corbett's finished building the #DryVault, a super-sophisticated, dessicant-dehumidified tool shed, it's time to whip out the Retrotec 5000 and FLIR T660 to see exactly how well he did. For more about any of the building or testing products used, visit:

Corbett Lunsford

Now that Corbett and Grace's 26-state Proof Is Possible Tour is over and 7,000 Americans have been brought into the illuminati of home performance, they get to have a real life for awhile. Here's a weird moment from their weird life in Atlanta.

How Much More Will a High Performance Home Cost?

Corbett Lunsford

The answer to this bass-ackwards question is: NEGATIVE DOLLARS AND ZERO CENTS. It costs LESS to build a high performance home, whether that means ENERGY STAR Home, a Passive House, a Zero-Energy Ready home, or any of a number of other green home certifications.  Here's why:

In his first Fall Fast Track week of 2015, home performance guru Corbett Lunsford answers the question "how much more will it cost to build my next home high performance?" The answer to the question is as straightforward as the question is ridiculous!

What If Cars Were Built & Bought Like Houses?

Corbett Lunsford


If cars were built like houses, each one would be built outdoors, exposed, in the middle of a muddy field.

If cars were built like houses, each car would be slightly different than all others, and would be built under different laws, depending on where in the country the muddy field was located.

Each part of the car would be put together and installed by a different company, with different workers guided by different supervisors, on different semi-dependable schedules, if cars were built like houses.

Sometimes in the rush to finish the car, the battery or steering wheel wouldn't arrive in time, so we'd just "put it on the punchlist" and get to it later.

If cars were bought like houses, no part of the car would be tested by anyone except the buyer, who'd just make sure the paint looks nice and the seats feel good.

If cars were bought like houses, car shoppers would never drive the car before they bought it, and no one would ask about the mileage per gallon, since no manufacturer ever bothered to measure it.

Also, I forgot to mention that these cars would cost hundreds of thousands of dollars- the biggest thing you'll ever buy.

If you hate this story, then next time you shop for a home, look for home performance testing and quality control checklists. Proof Is Possible.  Ask for it.

Corbett Lunsford

Today Corbett takes you on a tour of performance based building from a sampling of builders around the world, and realizes that the millionaires are going to be very angry when they realize what they're paying for isn't nearly as good as the affordable housing to be had on the other side of the tracks.
