Mid-century house in Atlanta
Posted by Allison Bailes on July 12, 2019
Let me tell you the story about a poor, young country boy who broke the law and launched me into my new project.  Back in February, I was driving home from work one evening when a driver T-boned me.  The crash totaled my car.  Fortunately, no one was hurt, but I was pissed because my car was paid...

Low indoor relative humidity in winter is common
Posted by Allison Bailes on February 15, 2019
I'm going to go out on a limb and make what you may think is an outrageous statement:  Water is the most interesting substance in the world.  Some of you may immediately respond, "Oh, yeah!  What about beer?"  (Or wine or Sidecars, Negronis, or Sazeracs or whatever your drink of choice is.) ...

What the heck is going on with this hotel room window?
Posted by Allison Bailes on January 22, 2019
The ASHRAE conference and AHR Expo were in Atlanta last week.  Because I live here, I didn't have to stay in a hotel but a lot of people I know came to town and did stay in hotels.  One of them, John Rockwell of ERV & HRV manufacturer Zehnder, sent me the photo above of the window in his room...

Filter bypass because of incorrectly installed filter
Posted by Allison Bailes on October 24, 2018
Indoor air quality (IAQ) researchers have established that little bitty invisible pieces of stuff that float around in the air are bad for human health.  Of course, being scientists, they don't call it little bitty invisible pieces of stuff.  They call it particulate matter (PM) or particulates. ...

Paracelsus, the father of toxicology
Posted by Allison Bailes on October 22, 2018
That face above is of a physician, alchemist, and astrologer named Philippus Aureolus Theophrastus Bombastus von Hohenheim.  He is deemed the father of toxicology and is better known by the name Paracelsus.  I begin this article with him because Dr. Brett Singer, at Building Science Summer Camp...

Crazy ventilation duct system mess
Posted by Allison Bailes on September 25, 2018
I've posted a lot of crazy duct system photos here in this blog.  Remember "Release the Kraken!"?  How about "Two Jellyfish Mating"?  And about three years ago I found one that instantly became my new favorite duct disaster.  But those were all in fairly standard homes.  They didn't have any...

Kitchen range hood
Posted by Allison Bailes on September 4, 2018
Energy efficiency is a gateway drug to building science.  When you really start learning about it, you come to the inescapable conclusion that there's so much more to making homes better than just saving energy.  A house is a system, you know.  There's moisture and comfort and indoor air quality...

The Corsi Code, a breakdown of how you spend your life
Posted by Allison Bailes on August 31, 2018
Back in 2004, as I was immersing myself in the world of building science and green building, I took the US Green Building Council's exam to become a LEED Accredited Professional.  I bought their book.  I took a study course at Southface to prepare for the test.  And that's when I learned a...

Bathroom exhaust fan brings humid air into the house
Posted by Allison Bailes on July 20, 2018
Nope.  Today is not the first of April.  Nor is this one of those special April Fools' Day articles I write at random times.  This one's real.  A white noise generator has now been used in at least one home to reduce indoor humidity.  And no, this isn't an amazing scientific breakthrough either....

ASHRAE 62.2 standard for residential ventilation
Posted by Allison Bailes on June 29, 2018
It's been a while since I've written about what I had been calling "The Great Ventilation Debate" back when Joe Lstiburek was battling the ASHRAE 62.2 residential ventilation committee.  The 62.2 committee meets in person twice a year at the two ASHRAE conferences and they just met last Friday and...
