Basic Building Science for Homes: Testing is the Cornerstone (from Home Diagnosis)

Corbett Lunsford

In our practice of diagnostics, inspections, computer modeling, load calculations, and verifying that healthy home targets have been achieved, we use a very simple approach, and here it is. From season 2 of Home Diagnosis: https://HomeDiagnosis.tv

How Hard is our ERV Working? Testing the Chemical Exhaust, Dust Samples, Rugs, and Formaldehyde

Corbett Lunsford

Corbett is testing his family's new high performance home for chemicals- in the dust of the floor, in potential allergens in the (very nice) used rugs they're getting, and even in the exhaust of their energy recovery ventilator (ERV). Thanks to Prism Analytical (http://pati-air.com) for being ready to give us the full rundown of what the results mean next month- don't forget that ANYONE can do these tests in any scenario- it's not rocket science.

How to Hotrod a Radon Mitigation System

Corbett Lunsford

We've been looking forward to showing off this system for a long time- the pipes for it were installed during foundation work at the start of construction, and now 2 years later it's finished, with the Fantech Rn4 EC fan (infinitely variable), multiple drainage systems, and a roof cap. Get the details on all the tweaks we had to use to make sure this system runs perfectly, which it's doing right now.

Indoor Chemistry Experiment #288: Home Pest Control

Corbett Lunsford

I used to wonder what exactly the chemicals in bug spray were doing to my pets and my kids. Now I don't have to care anymore. Freed up some brain space for more important things. Here's how you can do it too. Learn more at: https://HealthyIndoors.com

Healthy Homes for Multiple Chemical Sensitivity (MCS)

Corbett Lunsford

Tonight I interviewed Corinne Segura (https://www.mychemicalfreehouse.net/), one of my Mastermind students who helps people with Multiple Chemical Sensitivity (aka MCS, or Environmental Sensitivity), which she also suffers from herself. We discuss how home building and home improvements need to adapt to people with this condition, applied specifically to the TinyLab and our new 3,000 sq ft house that's almost finished.

Indoor Chemistry Test: Formaldehyde and VOCs during Construction

Corbett Lunsford

Modern homes are built more airtight than ever, and the engineered wood products that make such efficient use of our planet's materials also lean much more heavily on advances in adhesives, curing agents, moisture repellants, etc. Other building materials nowadays incorporate anti-microbial chemicals, anti-fungal and anti-termite compounds, and who knows what else (manufacturers DO NOT have to tell us what's in there, yet). The beyond-passive-house-airtight house we're building in Atlanta is an extreme example of all of this, and we'll happily be the guinea pigs to uncover the evolution of indoor chemistry from rough construction through ventilation activation, and move-in. Hayward Score has introduced us to a serious chemistry lab, Prism Analytical Technologies (http://pati-air.com) where we'll be sending the samples we take in this video. See what we're testing for, why, and how it's done.

Corbett gets serious details about indoor chemistry from Dr. Alice Delia, Laboratory Director at Prism Analytical Technologies (http://pati-air.com) about the test results from 6 samples of formaldehyde and Volatile Organic Compounds taken at the new build and the TinyLab.

“Airtight" Buildings Debunked by HOMEChem

Corbett Lunsford

I've been telling people that the 475 High Performance Building Supply membranes I build with are airtight but vapor open for years. Turns out, sometimes I'm an idiot. Here's the real deal. Featuring Delphine Farmer and Marina Vance of the HOMEChem Experiment.
