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.

When HGTV Starts Copying 'Home Diagnosis'...

Children Building Homes for No Pay on National Television: Science of Homes for Cable Networks

We shot a pilot episode for the Shark Week version of our show on PBS, and we think this could win awards. Not for science though. For slapstick. Are there awards for that?

Our children ‘design’ and ‘build’ a ‘high performance home’ that we then ‘test’ with ‘scientific diagnostics’ so that we can ‘educate the public’. Including ‘HVAC diagnostics’, ‘comfort analysis’, ‘pressure balancing’, infrared thermal photography, and a ‘blower door test’ that does not bode well.

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

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/

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

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.

How to Hotrod a Radon Mitigation System

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.
