APT Reports Feature Development: SUMMER 2015

Corbett Lunsford

Home performance guru Corbett Lunsford shows off the upcoming release of APT Reports 2.0, which goes beyond the performance testing required by the basic BPI and HERS certifications.

Holes in the House: JULY 2015 Building Forensics Mastermind

Corbett Lunsford

In the past month, I've investigated and tested a lot of homes, and made a lot of home improvement recommendations in each of them- it's always hard to boil it down to 30 minutes of material, but here's this month's crazy fast crash course through a few of my favorite jobs that used scientific testing to help homeowners, architects, developers, and contractors get their homes under control!

Building performance testing guru Corbett Lunsford walks you through four building investigations he was hired for in June, and often the opportunities popped out before any diagnostics were performed at all! See the Infrared Fail house get fixed, kitchen exhaust hoods and fresh air intakes get tested for airflow, and two homeowners who thought they needed new windows but actually didn't.

Every month's series episode is on the First Wednesday at 1pm Central, and it's always totally free!  Sign up now and be reminded at: https://attendee.gotowebinar.com/rt/3137914191179677698

Why Fall Fast Track Stands Alone in Building Pro Training

Corbett Lunsford

Like anybody else in any other profession, construction pros are expected to learn new things and get better at our work. Dirty secret: some of us don't do that at all. Amazing opportunity: those of us who DO get better and better leave the others in our dust, and we get not only our own loyal clients, we get theirs too.

I love my work, and I get paid to learn every day- it's incredible that there's always more to learn, no matter how deep you dig. When I first trained to become a HERS Rater, my instructor told me on day 3: "You ask too many questions- you just need to shut up and do what I tell you for the rest of the week."

corbettlunsford.jpg

I knew then and there that I would never be that guy. We need to ask MORE questions, not less, and we all walk around pretending we have a handle on what's going on when we usually don't have a clue! That feeling in high school- the one when you know you didn't do your homework and you're about to be found out- many of us live with that feeling every day in our work. It doesn't have to be that way. Now there's FALL FAST TRACK.

Proof Is Possible, and performance testing is the way to get there in buildings. It's a funny thing to be where I am in the construction industry: still a relative newbie at only 7 years in, but also one of the only people with both 7 years experience AND daily performance testing experience, still. Most of my colleagues at this level have primarily taken on management work, and don't actually crawl around in homeowners' attics and crawlspaces. Many home performance experts out there do not lug blower doors around or drill test ports in ductwork- they manage employees who do, or write about it, or make policy decisions for energy efficiency programs. I still do all my own hands-on work every day, and it makes me a better building scientist and teacher.

30-year HVAC veteran Mike Bowman of Dunedin Refrigeration in FL talks about how important Corbett Lunsford's Fall Fast Track was for his company in using home performance techniques to maximize quality and profits! #fallfasttrack #homeperformance

Which brings me to the free market. My hourly fee is on par with attorneys in many places, and that's because I don't just bring brains to the table- I bring tons of scientific gear, too. Anyone with both can earn a good living in home performance contracting, but you have to get out from under the umbrella of energy rebate programs to do it.

I attended a think tank recently, all about 'how to bring home performance contracting into the mainstream private market'. On the last day, I came right out and asked how many of the 40 building science experts in the room already worked entirely in the private market; and I was the only one. It made me feel both proud and like I must be an idiot for not taking the public money. But mostly proud.

I've learned to help homeowners solve problems and get more control over their homes, and earn a good living while I'm at it. And so can you. FALL FAST TRACK happens just once a year, and is limited to 100 pros. My goal is to have at least one home performance ninja in every market in the U.S., and if it's not you, it'll be your competition. And then there's Australia, Europe, Asia, and Africa to work on. Am I tired yet? Hell no, I'm fired up about it!

All we need to do is get the client, the homeowner/homebuyer, to understand what they should expect from anyone in the construction industry, and they'll naturally seek out the masterminds. It's worked for me. It can work for you. Let's do this.

Welcome to Corbett's oldest basement, a 1798 Boston dual-level nature space complete with open soil, trees, cobblestones, and magical feelings. Home performance is always about solving problems and minimizing risk, and this old house has no problem dealing with the basement's risk without any help at all- so far.

HVAC FAIL! Filthy Furnace Filter

Corbett Lunsford

Building forensics guru Corbett Lunsford didn't need to test this furnace filter to know it's wrong. Homeowners play an integral part of their own family's air quality and health, and making sure the filtration system is taken care of is super duper important.

The Blower Door Bucket

Corbett Lunsford

Sounds like a caveman tool, but it's actually the height of technology. I think this might be my favorite futuristic development of the 21st century so far. Take that, Apple!

Basically, when you're testing the air tightness of new construction multifamily buildings, you'll be moving fast and light (ideally), and getting your testing tools very, very dirty. It's a construction site. So why not rig up a toolkit that fits the purpose? Like a bucket, for example?

A classic technology from 2000 B.C.E. teams up with a classic technology from 1980 to create the most powerful performance testing tool rig the world has ever seen. Ever.

More than an 'Energy Audit' for Manufactured/Mobile Homes

Corbett Lunsford

Oh Guru of Home Performance,
Would you shed some light on the intricacies of auditing manufactured homes?? I have an audit to do on a 17 year old mobile home- I will do a blower door test with infrared... other than the walkthrough assessment and evaluating the duct-work, checking the underneath for the insulation quality, and what else possibly could be tested?
Thank you! Sincerely,
Kevin J.

Hi Kevin-
Thanks for reaching out!  If you keep your head in the 4-3-2-1 space (see below) and listen to the client’s pain (comfort/EE/air quality), then use testing to pinpoint the opportunities for improvement, it’s the same as analyzing any other type of building.  Your approach sounds solid, and I’d use any other diagnostics to solve the client’s specific pain points.  Think about what Motivational Metrics you can use to help your client take action with solutions.
Use my book Home Performance Diagnostics to help you perform any tests that seem applicable to pinpointing the cause and proving the measured home improvement.
Best of luck, and TAKE PICTURES AND DOCUMENT YOUR PROCESS SO YOU CAN WRITE A COOL ARTICLE ABOUT IT!  Have a great weekend.
Looking Forward,
Corbett

New Home Havoc: June 2015 Building Forensics Mastermind

Corbett Lunsford

In his monthly tour of a building forensics investigation of a home's performance, Corbett Lunsford shows how the problems of a new home can be measured, prioritized, and improved. Measured home improvement is the name of the game, even with a 6-month old house.
