In this blog, my architect James Plagmann and I begin to tell the story of the construction of Dan's new net zero energy homes. Dan begins by laying the ground, defining a few terms and describing his experience in this field.
I decided to build double 2-by-4 walls to achieve 14-inch thick super-insulated walls. This is just one way of achieving the high R-values for net zero energy homes.
Dan Chiras’ superefficient net zero energy home, floor joists, efficient floor design, band beam and rim joist
This blog contains a detailed list of most of my initial design priorities for my net zero energy home so others may benefit from my thinking and experience on creating a passive solar, net zero energy, green home.
In this blog, I highlight the earliest decisions I had to make to create a net zero energy home: how I was going to build the foundation and walls. Thermal bridging, air tightness, insulation, cost, and greeness are all key deciders.
This blog describes some of the details involved in building with insulating concrete forms, notably window and door buck details that you need to take into account
Once the ICFs are in place and the walls are very well reinforced, it is time to pour concrete. This blog illustrates the process in words and photos.
To ensure an airtight design, be sure to level and finish the top of the concrete wall and use sill seal below your bottom plates.
The devil is in the details in a net zero energy home. Every single step in the design and construction of a home requires efforts to ensure airtightness. The top of the foundation is one detail that deserves special attention.
The basement of Dan Chiras' net zero energy home is outfitted with PVC pipes, insulation and concrete.

For less than the cost of an SUV, a Michigan couple rehabbed their historic home to include solar panels and a geothermal system. The 110-year-old house now produces more energy than it needs.
From the outset, Earthineer was built to support and promote sustainability and homesteading as a lifestyle choice. Every feature we have planned has that goal in mind. What we have now is the foundation that we'll build off of.
In this blog, I describe two of the first and most important design considerations -- the length and depth of the home and the layout of rooms for optimum passive solar gain.
To me, the most important features of a sustainable building are not its technological wonders but its simple design features: common-sense strategies that should be incorporated whether the building becomes LEED certified, Energy Star certified, or is just trying to be environmentally friendly.

To build a net zero energy home, you'll need to design for passive gain. That requires a shallower footprint to ensure that the low-angled winter sun can enter and heat each room.
Insulation under the slab -- and lots of it -- is vital for the performance of a net zero energy home. So is the footprint. You can make the most of passive solar by creating a longer, narrower house in which each room is heated by the sun.
Be sure to install under-the-footing conduit to run electrical and water pipes, including sewer. I like to run pipes and wire under the foot to prevent penetrating the band joist or the foundation to create a more airtight, water tight home.
Don't forget to budget in the cost of deeper excavation and add $1000 to $2000 as a budget contingecy in case you run into bedrock.
Insulating concrete forms are an excellent choice for foundations for passive solar, net zero energy homes. They create a highly insulated, air-tight foundation, so essential for extremely high energy performance.
ICFs are not the most environmentally friendly green building product, but result in super energy efficient home, and offer many other benefits, that offset their origin from petrochemicals.
ICF walls must be carefully braced to prevent blowout.
Creating a net zero energy home requires that we eliminate all thermal bridging loss -- heat movement into and out of a building. All this starts in the basement.

So, what makes a flock of poultry sustainable? What is standard-bred poultry? If you purchase chicks from a hatchery, are they true to the breed? Why does every hatchery sell Rhode Island Reds and they all look different? Why do the Cornish Cross meat chickens have so many problems? Raising standard poultry is the only true way to improve the sustainability of quality local food while preserving the strength of Heritage poultry.
