Most of us would love to live in energy-efficient homes that are good for the environment and have low, low energy bills. But what are the best real options available? How do you create an extremely energy-efficient home that’s still affordable for most people?
Any net zero-energy home needs two things. The first is the sun, providing passive solar energy. The second necessity is retaining maximum heat.
As we continue to watch a zero energy home get built in my hometown of Boulder, Colorado, I’m digging the opportunity to learn more about building materials that I’ve seen in finished form but never in process. I like the
Existing homes that are certified as “green” sold for 30 percent more than homes without such a designation, according to an analysis of the Portland, Oregon, metropolitan region released today by Earth Advantage Institute, a nonprofit green building resource. Newly constructed homes with a sustainability certification sold for 8 percent more than non-certified homes.
This result continues a four-year trend in which new homes with third-party certification for sustainable construction and energy performance have consistently sold for more than newly constructed homes that had not been certified. The term "certified home" includes homes that received an Earth Advantage New Homes, ENERGY STAR, or a LEED for Homes designation, or a combined Earth Advantage/ENERGY STAR certification.

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.
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.
ICF walls must be carefully braced to prevent blowout.
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.
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.
An energy audit can help the homeowner determine the best strategies for improving the home's energy efficiency.
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.

There are two situations which do not require you to be heating your home: when it is warm and when you are not at home.

Some large electronics can use as much energy as a light bulb while in "stanby" mode, meaning you should unplug them when you leave the house or know you won’t use them for awhile. Having a large electronic setup plugged into a power strip makes it much easier to completely power it down, especially if it has a lot of plugs like a home theater system or computer.
