If you want to build a passive solar house, you’ll need to spend time upfront carefully considering your house plans. Here’s how one couple worked with a contractor and a designer to draw up and then finalize their small home plans with energy efficiency and lifestyle in mind.
Could you heat your house with a hair dryer? Super-efficient Passive Houses use very little energy.
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.
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.
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.
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.
Scaffolding is required to access the walls to pour the concrete. Scaffolding also helps support the walls.
Additional reinforcement is required around the garage door opening.

Being a homesteader and living off the land often means being subjected to natural conditions beyond our control, sometimes predictable changes of seasons and temperatures, other times curve balls such as unseen pest pressure, hard frosts in late May or heavy snow in early November. A lifestyle where these natural circumstances is the main determining factor for what gets done when is getting increasingly rarer – humans have gained what some consider an advantage by manipulating the world into a state where we, in many ways, can remain unaffected from the forces of nature.
