Willowside Rd., Day 14

John and Jane Doe's report is basically written. I have a template that I use that has been slowly built and improved over the past projects. It's a fine start but still requires a fair amount of custom writing, since each house has enough unique issues that need to be addressed.  There's report software out there such as Recurve's, EAI, or BizEE, but none have that personal touch that comes from a written report.  So here's some items from the report:Target Infiltration: 0.25 ACHn (1962 cfm50,…See More

"Tim, I didn't do a zone pressure test on the attic or the crawlspace with respect to the interior because both are well vented to the outside.  My personal approach is to always air seal the crawlspace from the bottom as thoroughly as…"

"How do you determine where you will be able to achive the infiltration reduction. Do you use Zone Pressure Diagnostics (add a hole method) on the attic to get an idea of the leakage from the attic or any other zone?"

Willowside Rd., Day 10, part 2

OK, I'm back from getting the dimensions of Doe's house, enter all the information into EnergyPro, and do an initial calculation. It looks like the house as it is has a HERS of 147, which means that the model predicts that it will use about one and a half times as much energy as a 'reference home', which is this exact same home if it was built to today's energy code requirements and has by definition a HERS of 100. 147 is not too bad but way above what we want. Let's see if we can get it below… Continue

Willowside Rd., Day 10

Well, it's taking a bit longer to get to John Doe's report than I'd expected and I've one molar less than a few days ago and a big hole in my jaw.  But, here we are.



I use EnergyPro because I learned it some years ago and I'm familiar with it. Plus, it's the one that's accepted by EUC (Energy Upgrade California), which I plan on applying for this project. Looking over the audit form, everything looks good. We should be able to easily improve Doe's house enough to get a couple of… Continue

Note: the following is not a comprehensive listing of all the details involved in a full audit.  It's meant to be a general description of the process so please don't think that you can read this and do one yourself.  Your and the homeowners' safety requires a full Building Performance training, at a minimum.

 



John and Jane are delightful. Pretty… Continue
