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

How to PROVE You Got What You Paid For in Home Improvements and New Construction

Includes a free copy of ‘How to Keep an Eye on Your New Home Construction or Home Improvement’

Tues. Nov. 7, 6-8pm
Woodward Academy Chapel
1600 Rugby Avenue
College Park, GA

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

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!

PODCAST #81: Keep Asking Questions with Hap Haven

Corbett Lunsford

Today Corbett talks with Hap Haven of US Green Home about where home performance contractors come from and where we're going (and how not to crash and burn on the way there). Sponsored by the Building Performance Workshop's 6-Week Mastermind Distance Course and Home Performance for Tiny Spaces course.

Home Performance Mastermind Minute: Week 4

Corbett Lunsford

Getting the job done right is a critical part of the job, but what about educating your client on what was done and why it's important? What about reminding them 2 years later? Metrics are the crux of the whole home performance movement, from pre-improvement testing through continuous monitoring.

How to Renovate a Home in Dallas- the RIGHT Way

Corbett Lunsford

Dear Corbett-
I am not a contractor, but a residential homeowner that has become increasingly interested in owning (and taking a part in creating) a high performance building. After going through several series of podcasts, I ran across yours, and immediately loved it because you went into greater detail about the things that I want to learn about; so I want to thank you for the podcast.
Onto my situation.... I am looking to buy an older (1940's) home that has no hvac, next to no insulation, and needs a good deal of work; but I believe it has the best potential for making a high performance home.... a blank canvas.
What I am having trouble with is finding the local rock stars that can really help me make my house as efficient and comfortable as possible with my given budget. Do you know of any really good people in the Dallas area that could get me on the right track? Thanks again for putting out all the info!
~Derek R.


Thanks for reaching out, Derek! I'm always happy to help, and I think the home you're considering is a GREAT OPPORTUNITY. A blank canvas is much easier to paint on, and when a house is fully 'finished' and has been renovated, it just means you'll have to dig harder and deeper to find and fix the issues that are lurking under the surface.
I'll hook you up privately with a few of my own black belts who are part of Fall Fast Track, but I also want you to know that when we take this show on the road next year for the Proof Is Possible Tour, we'll be creating a directory of pros who pledge to deliver guaranteed results across the U.S.!  Stay tuned here for further developments on that front, and keep in touch about your high performance home renovation!
Looking Forward,
Corbett

How Should a Homeowner Shop for a High Performance Home?!?

Corbett Lunsford

Hello Corbett,
I have been listening to your podcast and heard your request for ideas. You often mention the challenges in educating consumers, and I think my questions might be interesting to the non-professionals in your audience.
I just moved to Denver, Colorado and am considering purchasing a home for the first time. As a potential first-time homebuyer interested in air quality, moisture management, energy efficiency, and building durability, I expect that it is unlikely that I will be able to find a high-performing home at an entry-level price. With the expectation that I may need to invest in some retrofitting, I have a couple of general building performance questions:

Ascertaining current performance

Assuming that a first-time buyer probably will not have access to the sophisticated diagnostics described on your podcast during their search, what are some key things to look for that would indicate a high or low performance?
Utility bills can shed some light on energy efficiency, but how can someone gauge issues like air quality or moisture control?

Performance improvement opportunities

What factors influence a residential building’s suitability for a high-performance retrofit?
Are there factors that would influence the ROI of a retrofit for a modest home? And how could a homebuyer identify those?

Assembling a team

Do you have suggestions about how to assemble your team (realtors, inspectors, and appraisers) to help identify an entry-level home based on current or future potential?
What skills or expertise would you consider important?
Your podcasts have covered issues about financing for retrofits – so there may be nothing new to address here.
 
Basically, it would be great to be able to use a home performance lens during a home search to identify a property in which it is not too difficult or expensive to improve from decent to good performance.
As a potential consumer, I have enjoyed and learned a lot from your podcast. Thank you for thoughts.

Best,
B

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
