But there’s another home improvement that you may not realize can add serious value to your property: installing a solar energy system.
ne of the principles of Permaculture is “Stacking Functions” or making every structure/addition to your plan serve at least two, if not more, functions in the landscape. When we added solar panels to the homestead, we wanted to honor this principle—and constructing a small greenhouse allowed us to install the panels, as the light was not great on the roof of the house. The number of functions we have stacked on this small structure became very clear to me as I prepared for an upcoming solar homes tour.

Many people don’t know that most HVAC systems don’t produce more or less heating or cooling based on the room temperature – they simply blow air for longer.
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. Since it is still a bit chilly outside, you may want to consider setting up a routine of turning down the set temperature on your thermostat when you head out in the morning and when you go to bed.
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.
Tonight when you get home from work or school, call your utility company and ask what incentives they have for you to get an energy audit for your home. Many utilities have been offering free energy audits for years, but very few people have actually taken advantage.
Dan Chiras’ superefficient net zero energy home, floor joists, efficient floor design, band beam and rim joist

If someone told you that you were losing money just by sitting in your home, you would probably want to do whatever you could to change that. Well the reality is that your home is using up energy regularly, and there is a huge chunk of that energy that you do not even need. Luckily, we live in a time when technology is constantly coming up with ways to fix problems such as these. Here are some of the ways that technology can help to save the environment, as well as your wallet.
How packing snow against your house can add R-value to your insulation - and subtract energy costs.
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.
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
Additional reinforcement is required around the garage door opening.
Scaffolding is required to access the walls to pour the concrete. Scaffolding also helps support the walls.
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.
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.
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.
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.
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.
