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

Tour of the Building Performance Workshop in Atlanta

Corbett Lunsford

Welcome to the inaugural tour of the real life Building Performance Workshop on our high performance homestead in Atlanta, Georgia! From the translucent walls and roof to the airtight, insulated and dessicant dehumidified Dry Vault inside it, everything here is about making the invisible dynamics of building performance visible. Stay tuned for the blower door test, infrared thermal scan, air quality testing, and much more when the Workshop is built!

Keynote on Home Performance and Building Diagnostics

Corbett Lunsford

Corbett Lunsford delivered several keynote addresses in 2016 on building and touring the #TinyLab, home performance testing mastery, and how the construction and home improvement industry is evolving to incorporate proof of performance. You can watch this recording, delivered at the 2016 InfraMation conference in Las Vegas.

This is NOT a Roof Leak: What Condensation Can Do

Corbett Lunsford

Visit an attic (vicariously) with building performance expert Corbett Lunsford to find a tiny problem that may force us to replace the floor and ceiling of this building- and it might happen to you someday too! Stop guessing- Proof Is Possible. Get up in that attic and have a look!

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!

Dear Corbett: How Long Should My A/C Ideally Run?

Corbett Lunsford

Hi Corbett,
How long should the air conditioner run in a given day?  The upstairs zone was running for 16 hours yesterday, and 10.5 and 11.25 each of the days before.  Is that reasonable amount of time for the A/C to run given the recent summer temperatures?  We are still trying to get the developer in to fix the ductwork, and figured this might be an symptom of the problem.
Thanks,
Graham

Hey Graham!
Great question- your air conditioner is actually designed to run continuously when it's hotter than 89 degrees F outside.
The A/C's job is to both COOL and DRY the air, and if it's too big, it doesn't run long enough to wring the humidity out of the air. This leaves you with a muggy house, where you keep lowering the temperature to try to get comfortable.
So don't be concerned when your air conditioner runs for long periods on hot summer days- that means everything's working the way it's supposed to!
Looking Forward,
Corbett

Motivational Metrics: How Zonal Pressure Testing Works

Corbett Lunsford

In this home performance testing video, Corbett demonstrates advanced air leakage testing using zonal pressure diagnostics and a pressure pan. Learn how to get more out of your blower door with no extra investment in test equipment, how to interpret the data, and what to do about it during home improvement or new construction optimization. In the second video, Corbett clarifies his use of percentage-based interpretations of zonal pressure diagnostics, after several respected home performance pros had technical challenges for the method used.
