Natural beauty is priceless. We can take in and appreciate a great view because we don’t have any hope of owning it, and we can’t manipulate it. With our egos out of the way, we can learn to simply observe.
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.

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.
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.

Most conventional paints and coatings emit Volatile Organic Compounds (VOCs), which can contribute to poor indoor air quality as well as to smog. This overview includes a link to a product listing of healthier low-VOC, zero-VOC, and natural paints.
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.
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.
