More than the electricity needed to run these machines, the “rinse hold” hot water setting that many households use is the biggest energy drain associated with dishwashers – as much as 80 percent of the energy your dishwasher uses goes to heat water.
I decided to build double 2-by-4 walls to achieve 14-inch thick super-insulated walls. This is just one way of achieving the high R-values for net zero energy homes.
When you get home, go to your hot water heater, remove the cover and turn it down to 120 degrees (sometimes labeled “hot” as opposed to “very hot”).
Replacing a task that uses electricity with one that does not is a no-brainer when trying to save on your energy bill — and air drying is one of the easiest ways to go.
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.
Heating water is the highest drain that laundry machines and dishwashers have on your bill. Onaverage, water heating accounts for 18 percent of your energy bill.
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
A 3-part series on sustainable comfort systems for heating and cooling homes using passive solar design, solar electric power, system controllers and newly popular heat pump technology.
The basement of Dan Chiras' net zero energy home is outfitted with PVC pipes, insulation and concrete.
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.
Solar expert Joe Utasi hopes to have his home solar panel installation complete and running, and will have lots of pictures to show and discuss by the time the Seven Springs Fair arrives.

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.
