Energy Efficient Homes
What it's really like to buy, sell and market a green home.
Our efforts to improve energy efficiency in the United States might be faltering.
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.
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.
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.
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.
GO Home, built by architecture and construction firm G•O Logic LLC, received the U.S. Green Building Council (USGBC) 2011 LEED for Homes Project of the Year Award.
Custom Curve is the first glass window system with a structurally engineered framework that follows the curved wall of the yurt.
NXP's wifi light bulb would allow homeowners to turn LED and compact fluorescent lights on and off from anywhere, using any Internet-enabled device. Some say it's the first step toward building "smart" computer-controlled homes. Do we need this?
