Allison Bailes—Common Problems with Cold Weather Ventilation

When I woke up Saturday morning, the temperature outdoors was -40 degrees. The wind chill was -100 degrees! It was just unbelievably, impossibly, inhumanly cold outside. Fortunately, that was on a mountaintop in New Hampshire and not where I was. I happened to have woken up on a mountaintop in North Carolina, where the temperature was a much warmer -3°…

Using God Talk—or Not—to Help the Planet?

I am always impressed with the work of Susan Shelton and the Shelton Group. So an email message with the subject line from her office, “Age, religion & environmental messaging: what works?” immediately caught my attention.

In an Eco Pulse special report, “United We Understand,” the Shelton Group digs into their research on how best to reach an audience about environmental concerns. An associate of Shelton, Lea Ann Head,…

Degree Days Shuffle

3 Myths About Indoor Air Quality (IAQ)

Misconceptions About Air Quality and Home Performance

Recently I wrote a blog about the October 2017 firestorms in Northern California. I live and work in the city of Sonoma and was directly affected by the fires. My family and I evacuated our home and waited out the fires on safer grounds until the danger passed. We are OK, life has resumed, but the impact on the region will last for several years.

In my last post, I wrote about how air quality was impacted in the area, and how people responded by using N95 face masks…

Tell me again: Exactly where do I place that vapor barrier again?

There may be much confusion as to where vapor barriers are placed in building systems. Some people think that it really doesn’t matter just where these are installed whereby others believe that it really does matter.  A critical factor determining the vapor barrier placement is where the building is located; in Northern Climates where heating is the main concern and in Southern Climates where air conditioning is the concern. We…

Cool—and Warm—Clothing

“Why do you need to cool and heat the whole building? Why don’t you cool and heat individual people?” asked Yi Cui, professor of materials science and engineering at Stanford University.

Putting on or taking off articles of clothing works to keep a body cool or warm within a certain temperature range; outside that range we rely on heating systems and A/C to keep us comfortable. But what if one garment did both the heating and the cooling?

Cui’s colleague and postdoctoral fellow…

IAQ and Mold

What Is Mold?

According to the IICRC S520 “Molds are microorganisms that utilize organic substrates as nutrient sources in the presence of moisture.” Well, to put it more simply: molds are little organisms that like to grow on wet, organic materials (A.K.A. wood floors, dirt, and drywall).

Mold doesn't grow on inorganic materials; However, it can grow on the dirt present on the…
