At the Passivhaus job site in Falmouth, Massachusetts, architect Steve Baczek specified triple-glazed Makrowin windows from Slovakia. The windows were installed as "in-betweenies," and the perimeter of each window was sealed with Siga Wigluv tape.
To make sure that the installations were watertight, each window was tested with a garden hose equipped with a spray nozzle after it was installed.
At the Passivhaus job site in Falmouth, Massachusetts, architect Steve Baczek specified double-stud walls. The frame of a Passivhaus may not be as exciting as the thick layers of insulation, the high-tech mechanical systems, or the triple-glazed windows, but it plays a very important supporting role in achieving success.
In three new videos produced by Oregon builder Hammer & Hand, lead carpenter Val Darrah explains how he keeps air sealing in mind as he frames the walls for his current project, the Pumpkin Ridge Passive House.
Val explains why he prefers to use a router rather than a saw when he cuts out window openings in the OSB sheathing. He also shares his method of building window bucks out of 3/4-inch plywood.
GBA has made arrangements to provide live video streaming of an educational seminar by two renowned building science experts, Joseph Lstiburek and John Straube. Dubbed the Building Science Experts' Session, the seminar is being held on Wednesday December 5 and Thursday December 6, 2012, in Westford, Massachusetts. Sessions begin each morning at 8:00 a.m. Eastern Standard Time.
The video stream will be available at no charge to all GBA Pro members. A link to the live video stream will be added to this page on the morning of December 5, 2012.
Stopping air leaks is the single most important part of making a house more energy efficient. Every building needs at least one, and sometimes two, air barriers. One of the most common ways to install an interior air barrier is to follow the Airtight Drywall Approach.

When we developed GBA a few years ago, we knew that we would need, want, and eventually have a deep video program, but because the pile of work to do in order to meet our deadline was pretty darned big, and because we were a bunch of print guys and gals building this thing, we decided to let the video program sit on the back burner. We produced some, but didn't spend the resources to go hog-wild.
This construction site video of the Karuna House in Yamhill County, Oregon, demonstrates installation of a geofoam foundation that will superinsulate the bottom of the building envelope and help the project achieve Passive House and Minergie-P-ECO certifications.
