Best Place to Put a Bath Exhaust Fan

From 'Home Diagnosis' Season 2 Episode 9- most bathrooms are not designed for performance, let's admit it. If your mirror gets fogged up, if it takes 30 minutes to exhaust all the steam, if your ceiling drips or your walls have streaks on them, you can do better. Most of this, insanely, has to do with WHERE the bath exhaust fan is located. Here's your quick crash course to help you school all the builders, remodelers, and mechanical engineers in the world.

Headaches of HOMEChem: Chemistry and Microbiology of Homes

In partnership with Santa Fe Dehumidifiers, we're spreading the word on the intense dynamics going on in homes around the world. I keep it short and sweet in this 45-minute class on indoor chemistry, and you'll learn lots about chemicals, reactions, particles, and microbes, and the relationship to them of humidity and ventilation.

Ultimate HVAC Install and Testing: High Performance Heat Pump and Ductless Mini-Split

Boy, were we lucky to have these two people help us get our heating and cooling engines running: Kaleb Saleeby from Kalos Services (https://www.kalosflorida.com/) and the HVAC School Podcast, and Brent Ridley from H&M Services in Atlanta (https://handmservicesinc.com/) and the Tool Pros Podcast. These Applied Scientists in HVAC take our Mitsubishi Electric heat pumps (one ductless mini-split, one ducted air handler) from unboxing to perfect performance, using the latest tools and techniques. And thanks to everyone else who helped us with guidance along the way!

How to Test Indoor Air Quality

Corbett compares the Speck, Foobot, and CPS SmartAir IAQ indoor air quality monitors, and discusses why some measurements are more important than others.

Building to Control Humidity

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.

Retrofitting for Performance: Crawlspace Encapsulation

Using 475 High Performance Building Supply materials, Corbett and his dad are encapsulating the vented crawlspace of a one-story ranch home in Atlanta. See what a difference the improvements make to the test data from the Ultra-Aire Sentry system and the blower door.

The 4 P's to Solve Any Indoor Air Quality Problem

xEffortless Rocking means not trying to re-invent the wheel. Plenty of great home performance minds came before you, so take their ideas and make them your own. This one comes from Joe Lstiburek and John Straube at https://buildingscience.com/.

Home Improvement to Tune Performance: Test-In

Corbett runs a full enclosure diagnostic on a one-story ranch for his family before planning and performing the improvements on vented crawlspace and attic.

5 Kinds of Ventilation for HOMEChem Control

Ventilation is simple in concept- it moves bad air out and good air in. But the applications can be intensely confusing- Grace and Corbett help peel the onion of controlling home performance dynamics (and the HOMEChem issues we're learning more and more about) using fans and controls available around the world.

Featured systems are AirCycler, Fantech, Broan-Nutone, RenewAire and Ultra-Aire.
