The most popular post on this site is,’Should I Insulate My Basement Ceiling‘. Yay, 1st spot on Google searches! The number of reader comments is also a pretty good measure and I get a number of emails. There are tons of questions and some dissenting opinions. My view is that the easiest, most consistent approach …

An Energy Auditing Blog article on reducing mold risk by reducing the homeowner’s ‘water sports’ (water related activities in the house) was published at GBA last week. Allison Bailes, the self-described energy guy with the funny name, rightly pointed out that temperature plays a key role as well. Temperature Makes Humidity Relative Relative humidity is …

R-Value is a Lie (And Other Provocative Titles)

Or at least as Allison Bailes posted earlier this year, it is not a constant. Green Building Advisor once published my post on thermal bridging. The audience there is an extraordinarily knowledgeable one which leads to some spirited discussions. Following the thermal bridging article, there was some jockeying over whether R-value is an objective …

Problems with Crawlspaces – Venting and other Underhouse Ills

Crawlspaces are like the Loch Ness monster; talked about, rarely seen and potentially a bit scary.

But it raises an interesting question: how could one do the work on a house and ensure air quality, warmth, comfort and moisture control without an audit? What minimum provisions would a …

Concentric Vents and Blizzard Nemo

Blizzard Nemo clobbered Maine and most of the eastern seaboard this past February. Snow blanketed the entire coast, piling especially high in the Appalachian foothills. We slogged through a three foot dump in Portland. 50 MPH gusts whipped snow every way, sculpting enormous snow drifts in almost alien landscapes. That’s what our family woke up …

Sealed Combustion Heating and the Appliance Hot Tub Party

密封combustion systems are apt to become more central to efficient building as the new energy codes introduce air tightness standards. This implicitly means that you’ll need to pay attention to your heating system safety. And conveniently those codes also lay out explicit guidelines for combustion systems. Building and energy codes often get adopted …
