Well I got a new computer and so I am back. The old computer is getting the data transferred from it so I can have it on the new system. I do not have many tools at hand as a result. This system has to have the data transferred to it soon so I will not post here again for awhile. But here is a sign of progress.
Super Energy-Efficient Home in Vermont
Oct 10 2008 By Rob Wotzak
Modest House Built to Scandinavian Green Standards
This modest home may not seem out of the ordinary, but energy efficiency specialist Efficiency Vermont calls it extraordinary — “Best of the Best” and “the most energy efficient home in the state,” to be specific. With a HERS score of 95.3 out of 100, and four years of energy bills to document its performance, the building deserves the accolades. Builder Al Rossetto leaves nothing to chance: he has used the same construction details to lock in five-star Energy Star ratings for every home he has built since.
Is Vermont the new Scandinavia?
The shallow, frost-protected footing is possibly this home’s most unusual detail. Northern Vermont’s deep frost line and rocky soil make building conventional foundations a challenge. A shallow bed of gravel surrounded by a horizontal apron of rigid foam insulation — a system used in Scandinavia for decades — worked well here.
When paired with an insulated concrete form (ICF) foundation, this system ended up saving energy and materials. The walls and roof are all structural insulated panels (SIPs), which go up quickly and provide a tight shell. Energy efficient windows with triple glazing and multiple low-e layers (also standard equipment in Scandinavia) complete the package.
Go there and read. More later.
