Central Vacuum System with HEPA Filter: Performance Testing for a Healthy Home

Corbett Lunsford

For our forever home, we chose the NuTone PurePower 650 central vacuum, which I piped, wired, and installed myself (not very difficult, though parts are hard to get ahold of in a hurry, if you run out).

Check out this system, and other Broan-NuTone machines: https://broan-nutone.com/

Dehumidifiers How/What/Why: Installation and Testing of Ultra-Aire 120H and MD33

Corbett Lunsford

Modern homes need dehumidifiers, separate from the air conditioner. We chose the highest performance units available, Ultra-Aire's 120H and MD33- here we'll give you a full tour of the planning, sizing, installation, and testing of these machines in our performance-tuned, self-built home.

See these two dehumidifiers we selected for our home:

How to Design, Install, and Test a Perfect Kitchen Exhaust and Make Up Air System

Corbett Lunsford

Using Fantech's hood liner system (https://www.fantech.net/our-solutions/kitchen/exhaust-air-system/) and active make up air system (https://www.fantech.net/our-solutions/kitchen/makeup-air-systems/) with custom grilles from Stellar Air Vents (https://stellarairdecorativeventcovers.com/), we made our home a test lab for tuning indoor chemistry with state of the art ventilation. Thanks to LBNL’s Brett Singer for helping me get in high gear on this topic.

Ceiling Fans are HVAC Heroes in High Performance Homes

Corbett Lunsford

See how our forever home's 7 ceiling fans play a pivotal part in our performance-tuned house's HVAC system. The Wrap Custom is among the most efficient fans in the world in 2020 (420 CFM generated per Watt), and they are a silent and beautiful reminder of the invisible dynamics at play around us all day, every day.

Uncomfortable Homes Explained: How Air Sealing, Insulation, HVAC and Thermal Mass Actually Works

Corbett Lunsford

From the upcoming Season Two of 'Home Diagnosis': through a 5-day recording of temperature, humidity, and dewpoint with a datalogger, see the actual performance curves of five built environments on our property. Watch the evolution of primitive to advanced built environments, from an open-air workshop to a lived-in high performance home- the effect of air sealing and insulation alone is pretty incredible when you see it like this.

First Blower Door and Duct Testing Certification Trainings

Corbett Lunsford

D55CB387-29EE-485C-99F2-BF38BABB7AB2.jpg

Our first 8 newly certified DET Verifiers came through our brand new training center at our home in Atlanta! It was a thrill, honestly, since I haven’t given any in-person trainings in over a year (like most trainers). Everyone passed their certification exams, which doesn’t always happen- they have to earn 80% on both written and hands-on exams with the equipment, and do a bunch of geometry calculations that we all forgot since high school.

DETclass2-groupshot.jpg

They all totally rocked the use of the blower door and duct tightness tester, and are ready to rock the houses in Georgia, South Carolina, Tennessee, Kentucky, Indiana, and Alabama (no joke, that’s where all these folks work). Super happy also that we didn’t have a bunch of last minute registrations, which used to be the bane of my existence. Sold out weeks ahead of time- very grateful!
