Tiny House Building Science Basics

Corbett Lunsford

1. Tell us about the TinyLab:

Our #TinyLab is a 210 sq. ft. house on wheels we designed and built ourselves to be the best performing home most people have ever seen. It’s supremely airtight, quiet, and comfortable, while also being equipped with the best heating, cooling, and ventilation systems in the world. We’re showing Americans how home performance works with our non-profit Proof Is Possible Tour. There’s this mythology around houses that ‘they all have problems, that’s just how they are’; it’s just not true.

2. How did the TinyLab start?

Well, the dynamics of home performance are based in physics, which is tough to explain- our colleagues have been trying for decades. But these dynamics can have real consequences for your family- they can cause sickness or even death. We thought, ‘how can we show consumers home performance?’ The #TinyLab is what all homes could evolve to be, whether they’re big or small. It’s a critical time for this, since building codes in all 50 states are requiring performance testing.

3. What are the major findings between the relationship of health and homes?

Two major health problems anyone can find out themselves for starters: dampness and carbon monoxide (CO). The symptoms of CO poisoning are ‘flu-like’, but ask yourself how many times you’ve been to the doctor with ‘flu-like’ symptoms and ever been tested for CO poisoning (never, say most people). And though we know dampness causes mold, mildew, dust mites, etc, do we think about what causes dampness? It’s usually air leakage- air leakage is the single biggest problem in most homes.

4. How do you protect yourself from carbon monoxide poisoning?

The only way to be sure is to test. Whole-home performance testing can prove if your gas stove, water heater, furnace, or fireplace are exhausting properly and creating very little CO. We have a Defender ‘low-level’ monitor in the TinyLab. Your normal CO detector won’t always protect you. If it’s what’s called ‘UL-listed’ then it specifically will NOT protect children, pregnant women, ill or elderly people from low-level carbon monoxide poisoning. And it says so right in the manual. Crazy.

5. What are 5 tips you have for any homeowner/ renter reading this?

One: Your home is a system of interacting parts, so anyone who says one product can fix it is lying or naïve. Two: Proof is Possible- act on diagnostic proof before you undertake surgery on your home and before you pay your contractors for measured improvements. Three: airtightness is good- don’t let anyone tell you we should build crappy houses that can ‘breathe’ through the cracks. Four: ventilation is critical- take stale air out, bring fresh air in. Five: Our YouTube channel is called ‘Home Performance’- you can learn tips 6 through 1000 there.

6. What specific diagnostics are recommended for homes?

Great question! Blower door testing is most important- our TinyLab’s test proves that as first-time homebuilders, we achieved the most airtight standard in the world (that’s what makes it so quiet in here). Infrared thermal photos prove our insulation works. Pressure testing proves our home is not sucking air back in through exhaust fans or chimneys. Airflow testing proves our HVAC system’s working as designed. Air quality tests prove our family isn’t being poisoned. Proof is possible. Ask for it.

Building Our Forever Home DIY: Lessons Learned

Corbett Lunsford

What have we learned designing and building our own forever home? Well, kind of a lot. But we tried to keep it short, so here’s a 40-minute long tour through our brains while we’re still under construction.

We’d LOVE your support to keep bringing all this free education to the world. You can support us for as little as $5/month at: http://Patreon.com/HomeDiagnosisTV

High Performance HVAC Systems Preview

Corbett Lunsford

Now that the Mitsubishi heat pumps, Ultra-Aire dehumidifiers, and Fantech ventilation systems are onsite, Corbett gives a sneak peek at how they all fit together with the upcoming Fanimation fans and Kichler low-heat lighting to tune the indoor environment.

How to Install WRB Sheathing (ForceField)

Corbett Lunsford

Grace and Corbett show the latest development on their home build- the wall sheathing, which is also the air tightness layer and weather barrier. It's called ForceField, and here you'll see a demo of why it's such an important component in the system, and how to install it for a higher performance home.

Building to Control Humidity

Corbett Lunsford

It's easy to overthink building science decisions- here, Corbett quickly summarizes the basics of controlling moisture in the Lunsford family home build, and for any home. Interactions between materials and systems like GP ForceField, Rockwool Insulation, and Ultra-Aire ventilating dehumidifiers are simple to understand if you use the 4-3-2-1 approach.

Framing the Floor at our High Performance House

Corbett Lunsford

Hear Grace and I discuss some of the interesting challenges so far as we begin the framing of the floors and walls of our family’s high performance house in Atlanta.

5-Layer Slab for High Performance House

Corbett Lunsford

Home Diagnosis TV series co-host Corbett Lunsford shows the installation of the 5 layers of performance control under his family's new house. Thanks to Royal Building Products, Rockwool Insulation, Stego Industries, and the subcontractors who worked so hard to get this right! More at: https://HomeDiagnosis.tv/atlanta-homestead

2 Years Later: is #TinyLab Still the Highest Performance Tiny House on Wheels?

Corbett Lunsford

Grace and Corbett built the world's highest performance tiny house on wheels in 2016. It was perfect. Then they toured it 13,000 miles across America and let 7,000 people come inside to feel, hear, and smell what perfectly tuned home performance is like.

What's the house performing like now, after all that torture? And under 2 inches of snow in Atlanta, Georgia? See for yourself in this 20-minute tour, complete with testing, demonstrations, and metrics that show Proof Is Possible, even for people who have never built a house before. The #TinyLab is still the undisputed most scientifically superior home performance demonstration in the world, and we sincerely hope others start challenging our work!

Today Corbett talks with Bill Lazar of St. Johns Housing Partnership about how his organization built hundreds of affordable homes in St. Augustine, Florida, that are scientifically superior to the million dollar mansions going up across town. Recorded from the #TinyLab on the Proof Is Possible Tour.
