Please see Audrey Allen's post on August 1, 2011 for a description and more information about some of the features pictured below.

Outside corners are open to allow for insulation

Exterior Insulation

Header Insulation and Sealant

Raised Heel Trusses provide room for more insulation where exterior walls and roof intersect. 

Roof Trusses stacked directly over each 2' o.c. wall stud to transfer roof loads directly down to the foundation.

For those who are not familiar with the details that make a home more efficient, take a peak at this home as it progresses. In this rough framing stage, you can see a few items such as the 2' on center wall framing. This saves lumber and allows for more insulation versus wood in the walls which equals less heat loss in the winter and less gain in the summer. The roof trusses are then stacked directly over each 2' wall stud to transfer the roof loads directly down to the foundation. Also notice that the trusses are taller where they sit on the outside walls than standard trusses.n This is called a raised heel or energy heel. This allows for thicker insulation where the roof is closest to the ceiling, typically a weak point for heat loss in standard construction. We have also kept outside wall corners more open for insulation (typically crammed with wood or simply uninsulated due to inaccessibility) and blocked perpendicular interior walls with a stud turned flat so that it can't conduct heat straight through to the outside of the house. We'll tell you more as it happens...

Thank you everyone for your hard work on this project. I had a great time helping frame the LEED home last week. We have an incredible group of people involved!
