DIY Passive House? Nothing "Passive" about That

Building to the Passive House standard is hard enough for the pros. We get a peek into what happens when you try to go it alone. Zip-taped and on piers. We were lucky enough to visit while seams and interior I beams were still vi... Process makes (almost) perfect Ironwood's own design/build process is a large part of this project. Eli points out that while the company is a high-end residential design/build company, at the shop they're also computer-assisted manufacturers. This has been quite a wet year (it's raining as I write this, actually) in Southern Vermont, but that hasn't stopped Ironwood from moving steadily forward with this project. By utilizing CAD/CAM processes in a year with 50+ inches of rain, they were able to wait out storms with pre-cutting, pre-painting, and pre-construction. Ultimately, this allowed the house to be dried-in in just three onsite days--two of crane work and one day sheathing the roof. Back on their own blog , Andrea and Ted tell tales of having to adjust their expectations and let go of some things they once held dear like a 30,000 Btu wok ring. Since the house is sealed so tightly, there are many challenges around combustion and air-exchange for appliances like gas ranges and dryers. But finding alternate creative solutions is part of the fun on a project like this! Working with what's available An example we witnessed on our trip involved availability of materials. Some that they wanted to use weren't available in New England or were only sold by the pallet, as was the case with the 24-inch I-beams for the roof joists. To avoid excess materials and spending, Eli redesigned the roof, which spans 26+ feet, to use exactly one pallet of beams. The solution? The West wall goes all the way up past the joists to eliminate a need for that pallet-busting 24th beam. For more in-depth insight into the products used on this project, look for an upcoming blog post from Jennifer Atlee. Passive House: an active collaboration Ted and Andrea originally set out to build this project on their own. They soon realized that it was going to be quite complicated and called in some great collaborators. Eli says of this relationship that: [w]e can connect dots, but there's no one of us that can really know what we need to know to pull off a building like this. I know [Ted and Andrea] spent a lot of money at the start in those soft costs. And I'd like to think that someday, that through either [BuildingGreen's] work or larger communities of people--it doesn't have to be just one person taking that on. But I feel really glad that these guys took it on. If you'd like to come along for the ride, listen to an audio recording of our tour .
