Diagnostics are the heart of all home performance work- testing will set you free with proof and prediction!
Home performance articles and stories from the field with internationally respected building forensics guru Corbett Lunsford at the Building Performance Workshop. Hear new episodes of the Building Performance Podcast, see new videos from the Home Performance YouTube channel, and learn all about how diagnostic testing (more than an 'Energy Audit') can make home improvement and new home construction a proven process!

Grace and Corbett are building a performance-proven tiny house on wheels called the Tiny Lab! It's going to be built from November to February, and it starts a 16-city US Tour in March of 2016. The Crowd Sourcing Campaign is happening NOW on RocketHub- CLICK HERE TO PARTICIPATE IN THE TOUR! Here's the full series of four webinars from August 2015 detailing the engineering of a super cool tiny house on wheels!
In #1: SHAPE AND LAYOUT, Corbett and Grace show the 3D sketchup model of the Tiny Lab, and bring engineer John Bergman in for some heavy lifting to do with pinpointing the center of gravity on this 24 ft trailer tiny house.
In #2: AIRSEALING, INSULATION, & WEATHER BARRIERS, tour the process of energy modeling the tiny house to determine the optimal R-values and level of airtightness, and hear about vapor barriers, moisture control, and drainage.
In #3: HEATING, COOLING, AND VENTILATION, you get a taste for how wrong a lot of the discussion goes about homes in general, and tiny homes especially. The HVAC design, including Manual J heat load calculations and hourly solar gain curves are analyzed and used for things as straightforward as deciding which direction to park the tiny house.
In #4: BELLS & WHISTLES, see behind the design of the solar PV kit, formaldehyde-free plywood built-ins, composting toilet, off-grid plumbing challenges, and luxury items that just add that quality of life that tiny house occupants are seeking.
We really hope you'll tune in for the videos of construction- you can subscribe to our YouTube channel right now with one click!
Tiny home performance is made even more perfect in our third presentation in this tiny house engineering series! Watch as I walk you through the design and engineering of the heating, cooling, dehumidification, bath and kitchen exhaust, fresh air ventilation, and water heating systems in the Tiny Lab.
If you stay tuned to the end, you get to hear me realize I'm a total idiot! Fun stuff!
Today Corbett is psyched to again talk with Lew Harriman, the master of dehumidification and author of lots of books on moisture control, about guess what! Lew takes us on a tour of macro-drying philosophy, down to the nitty gritty of ERVs and hairdryers and wet spots on your carpet. Sponsored by Corbett's Fall Fast Track 6-week mastermind course in free market home performance.
PODCAST #49 THIS HOUSE SUCKS, BUT NOT VERY HARD: Brett Singer, scientist, shows us where depressurization testing has led us astray
Today we talk with Brett Singer, air quality scientist at Lawrence Berkeley National Laboratory, about the red herring of worst-case depressurization on combustion testing, and the actual hidden enemy in every home.
