Happy birthday to Willis Carrier!  He invented modern air conditioning and changed the world.  In his quest for a device to control humidity in the Sackett-Wilhelms Lithographing & Publishing Company in Brooklyn, New York, he invented a device that changed migration patterns in the United...

A certified Passive House in Seattle, Washington
Posted by Allison Bailes on January 2, 2018
Well, another year has come and gone. Out with the old, in with the new, and all that. A time for introspection and resolutions. Taking stock of where we are and plotting a course for where we want to be. All because of a somewhat arbitrary turning of the calendar from one year to the next. A...

Stop Plate Tectonics, one of my favorite T-shirts
Posted by Allison Bailes on June 2, 2017
So the United States has announced it's withdrawing from the Paris Accord, the international agreement with nonbinding measures to mitigate the effects of climate change. Now everyone's up in arms, speaking in exasperated tones about the travesty of this decision. "But...but...the science," they...

Lots of snow out West but warmer than usual temperatures in winter 2016-17
Posted by Allison Bailes on May 8, 2017
We've had some beautiful, cool weather here in Atlanta the past couple of days. It's about 50° F outdoors as I write this. The high yesterday was only about 70° F. We're getting a few more heating degree days (HDD) in the middle of May. (Heating degree days are really just another way at looking at...

Everyone knows about the impact of burning fossil fuels on global warming. Maybe not everyone believes it, but scientists first started focusing attention on increasing carbon dioxide levels way back in 1827. The impact of insulation on global warming, however, is relatively new. About a decade ago...

Insulation and Global Warming
Posted by Allison Bailes on November 21, 2016
At the North American Passive House Conference in Philadelphia in September, I gave a presentation on the global warming impact of insulation, an issue I've been discussing off and on since Alex Wilson wrote his paper on the topic back in 2010. In my presentation, I covered two different aspects of...

Stephen Hawking
Posted by Allison Bailes on November 18, 2016
There's big news this week. No, I'm not talking about the delayed opening of ski resorts out West because of the lack of snow. And, believe it or not, it has nothing at all to do with Donald Trump. I'm talking about Stephen Hawking's prediction that we humans have only a thousand years left here on...

Posted by Allison Bailes on November 9, 2016
Supply and demand are two different things. When you think of an energy code, say the International Energy Conservation Code (IECC), you probably think of demand, not supply. Conserving energy, after all, means reducing demand. It's related to supply only indirectly. As a result, you might expect...

Like many energy geeks, I track my electricity usage and costs. I've been doing it for decades. (Unlike Danny Orlando, however, I haven't stayed in the same house and watched as the home energy improvements kept lowering that usage.) One thing I've noticed in the past few months is that the...

Posted by Allison Bailes on September 29, 2016
Solar energy has sex appeal. If you want to show the world you're doing something to reduce pollution, you put photovoltaic (PV) panels on your roof to generate clean electricity. Even better, you drive a plug-in hybrid or an all-electric car and charge your car's batteries with your solar panels....
