Tuning the Enclosure of our Atlanta Home Build

Corbett Lunsford

Corbett digs into the weather barriers, structures, airsealing and insulation layers of the high performance house in Atlanta, which will be featured in season 2 of the Home Diagnosis TV series.

*CORRECTION: Pango Wrap is 15-mil thick, not 20, but is still a 0.01-perm vapor barrier.

TOOL REVIEW: DG-1000 from Energy Conservatory and Minneapolis Blower Door

Corbett Lunsford

Corbett gives a crash course in the TEC’s DG-1000 used with Minneapolis Blower Door equipment (including the Duct Blaster, TruFlow Plate, and Exhaust Fan Flow Meter). TEC took away a few features like Equivalent Leakage Area estimation, but added the Tubing Assistant and firmware updating, which could endlessly add features based on user feedback.

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.

Corbett and Grace are too busy with the #TinyLab and Proof Is Possible US Tour, Home Diagnosis TV show, and baby Nanette to host 2016's Fall Fast Track 6-week mastermind training in home performance. Join us in the spring instead!

'Home Diagnosis' Finally Puts Home Performance Testing on Mainstream TV

Corbett Lunsford

Grace and I have been trying to make a TV show about home performance testing for years- we've tried three times so far!  This is how it works traditionally:

  1. You get a network executive to want to see you as a couple onscreen because they think you're quirky or weird or otherwise compelling in a I-can't-look-away kind of way
  2. You work with a production company and pay out of your own pocket to shoot a 'sizzle reel' that shows off the personality of the hosts
  3. You remind yourself and everyone else that your show is about SCIENCE, not about relationship drama and being quirky or weird
  4. They remind you that no one cares about the topic in reality TV
  5. You feel frustrated and you throw the whole idea in the garbage because you don't want to play their stupid game

So we've decided to make the show ourselves, without asking anyone's permission. We find that works best for us- whether self-publishing a book (Home Performance Diagnostics) or making a feature film (The Other One), it always seems to work perfectly when we don't have someone breathing down our neck to conform to 'the way things get done around here normally.' Here's the show that will actually make it onto mainstream television: HOME DIAGNOSIS.

In 2014, we pushed hard for a show called PRESCRIPTION HOME PERFORMANCE to get made, but it went exactly nowhere. We went to the national RealScreen Summit, a non-fiction television programming conference (yeah, I know!), met with all kinds of networks to pitch the idea, and finally had Science Channel interested until they finally said, "wait, we don't want to compete with HGTV." And that was that. But you can still see what the show was like here:

And way back in 2009, we worked with our friends and client Sandy Gordon to make OUR GREEN COMPANY, which resulted in all of us being told by the Discovery Green channel that 'green' was a fad. Look at these kids- so young, so fresh, and maybe clueless!

Stay tuned for developments on HOME DIAGNOSIS- at the very least, it'll show on PBS just like This Old House does, and at most, it'll be running 24 hours a day on every channel there is.  Probably it'll be somewhere in between!

If you'd like to participate in the making of this show, please reach out to us about it!

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

SEPT 2015 Building Forensics Mastermind Series

Building forensics work shown in detail! Watch as I give a tour of a few of the diagnostics projects we worked on in the past month, especially a battle between two flow hoods that are both past due for calibration, duct tightness testing failures and what to do, and when performance testing professionals should get paid for their work.

PODCAST #74 SAFE, HEALTHY, AND TESTED: BPI's Larry Zarker means home performance, not VD

Corbett Lunsford

Today Corbett talks at the Habitat X thinktank with BPI CEO Larry Zarker about his passions: helping contractors, building homes that stop sending you to the emergency room, and how to infiltrate the health insurance industry to help make all that happen. Sponsored by the 6-week Fall Fast Track distance mastermind course for home performance black belts.
