Energy Retrofits Without Energy Audits

    While some building folks have opined that energy audits are less than essential, I am admittedly biased. It is what I do. 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 Belated Energy Auditor New Year’s Resolution

by Erik North on May 20, 2013

An Energy Auditor's New Year's Resolution

      The beauty of this title given my article backlog is that I can publish it any time, even next year. It’s multi-purpose. The folks at Maine Green Building Supply have been discussing the ‘Pretty Good House’ for several months now and I’ve had the chance to sit in on a few of […]

Post image for The Worst House Ever Audited (Was Built in 2008) Part 3

    To recap: Last post I started reviewing possibly the worst house I ever audited. The house had built in 2008, which hit one of my pet peeves: That new automatically means good. But to reiterate a buddy’s favorite saying, “a house built to code is the worst house you’re legally allowed to build.” […]

    Last post I started reviewing possibly the worst house I ever audited. There have been others with a similar magnitude of issues. But this house had built in 2008, which some folks thinks signifies no worries. But to reiterate a buddy’s favorite saying, “a house built to code is the worst house you’re […]

    OK, maybe THAT house wasn’t built in 2008. One thing apt to set my teeth on edge as an auditor is when folks casually assume that a new home won’t have energy problems or be inefficient. I was just discussing some marketing with a friend, who casually dropped that weatherization and efficiency work […]

My First Energy Audit…Part Uno

by Erik North on January 2, 2013

Post image for My First Energy Audit…Part Uno

  I thought I’d start the new year by looking back: My first (paid) auditing gig. My first energy audit was a few months after I’d completed Maine State Housing’s Auditor certification program. It was a two week program, one week of class work and one week of field training. Just enough learning to make […]

Post image for CFM50 And ACH50 – How They Work (And How They Don’t)

    CFM50 and ACH50 are two blower door measures that I bandy around all the time but have never defined. If I were trying to play it mysterious I would say, hey, we have to keep some of this mysterious. A more ‘actual’ reason would be that, despite my sincere belief otherwise, talking about […]

Blower Door 2 – Blower Door Harder

Post image for Blower Door 2 – Blower Door Harder

    And that post title does sound vaguely raunchy but oh, well. Continuing from from a few weeks back where I realized I ought to do a post talking a bit more about how these tools are actually used. Blower doors are spoken of in reverential tones in energy circles. Or at least they […]

Post image for Energy Audits in New England – Buildings Both Old and Cold

  I recently (a few months back) proposed to Allison Bailes of Energy Vanguard that we write a North vs. South energy audit article. It may yet come about (and hasn’t so far because I’m miserable at follow through) but it’s a worthwhile topic. Audits and the energy priorities they consider are very different based […]

Performing A Google Audit

  In some energy circles, there’s derision toward what some term the ‘science project’ energy audit. The idea follows that energy auditor engage in gobs of scienctific kabuki to justify the expense of their services. Auditors trot out blower doors, infrared cameras, conduct flue gas tests, combustion zone testing and zone diagnostics in service of […]
