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.
I am especially concerned with the electricity hogs that keep us burning coal.
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.
Comly Wilson, Associate with CleanEdison, a solar installation training provider, offers her tips to remedy 6 common mistakes solar PV installers make when setting up new photovoltaic systems.
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.
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.
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.
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.
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.
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.
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.
ICF walls must be carefully braced to prevent blowout.
