Off the Grid Homes combines beautiful images with technical information for sustainable homes.
The book by architect Lori Ryker is less of a manual for systems to be used in off the grid homes (though it does include good information about the systems and strategies that are used in sustainable off the grid living) and more of a showcase of state of the art homes at the intersection of appealing architecture and high sustainability.

For many, the phrase “off the grid home” brings associations of a rudimentary, hand-built, rustic cabin. It usually suggests a rough hewn character and images of anything other than refinement and elegance. But that image is far from the case in examples presented in this book.

Last week, in writing about this year’s AIA Committe on the Environment’s COTE Top Ten winners, representing the best “examples of sustainable architecture and green design solutions that protect and enhance the environment,” I asked “Are COTE Winners Too Much of the Same?” While I am certain I’m not alone in that viewpoint, I’ve come across some other perspectives on that question.

One of the jurors from the panel that selected this year’s COTE Top Ten wrote about her experience and some of the things that she saw in the jury. And the question of great architecture versus green architecture was also raised in the AIA weekly newsletter this past week as well. The COTE Top Ten showcases some very attractive buildings with some serious green building credentials (LEED Gold and Platinum buildings and a building that claims “carbon neutral opearations”, to name a few). But the larger question seems to be how much green building and good building design are, or can be, connected.

Earlier this year, headlines were made on the announcement of biotech start-up Coskata promising to revolutionize the production of ethanol with a process that could use a variety of feedstocks, ranging from wood chips and switchgrass, to old tires, and even directly from municipal waste. Most importantly, it did not rely on corn or other food stocks in order to produce fuel. At the time, Coskata was predicting an aggressive timeline, with a pilot demonstration plant to begin operation in 2009, and a first full-scale plant to be underway by 2011.

Last week Coskata announced the location for their pilot demonstration plant, a facility that will begin producing 40,000 gallons of ethanol per year, starting in 2009. While that is only a tiny drop in the proverbial bucket, it’s another step along the path to having a full-scale plant in operation and producing 50 to 100 million gallons of ethanol per year.

As has happened before, with gas prices continuing to climb, the demand for improved fuel economy will increase as well, and all manner of improvements and upgrades that promise to help get better mileage will be touted. Some offer real benefits; others are pure snake oil.

An improvement that offers both improved mileage and increased horsepower seems counterintuitive at first. After all, the tradeoff that hybrids and other economy vehicles offer seem to be one of reduced horsepower and acceleration in exchange for improved fuel economy. So how can you have both?

The winners of this year’s AIA Committee on the Environment (COTE) Top Ten Green Buildings were announced this week, and there certainly are some very attractive buildings among the lot. Some of these buildings are certified, or in the process of becoming certified, to high LEED standards, in addition to their COTE Top Ten recognition.

But while I’m excited by some of the design presented in this year’s lineup, there are some troubling aspects of the roster as a whole that struck me almost immediately.

As part of their Earth Day coverage, NPR’s All Things Considered  took a look at a LEED Platinum home renovation in Washington DC.  Peter Yost from the green building resource BuildingGreen helped to explain some of the possibly unfamiliar green building terms and explained how the elements of this renovation contributed to its being one of the greenest homes in the country.

While building tours on the radio can’t show pictures, the NPR website has several […]

Tuesday, April 22 is Earth Day, and we thought that a couple special posts would be appropriate on this date.  Building has an enormous impact on the Earth, and green building offers the opportunity to lessen or eliminate many of those effects. Today, in a series of articles titled Elements of Building, we take a look at how Water, Energy and Materials each factor in to building operation and building design.

In addition to discussing green building, let us also take this opportunity to remind you of all the other Green Options blogs in the network and invite you to take a minute to look at some of the other writers and their Earth Day thoughts:

At the heart of all building projects are the materials, the stuff, the bricks and sticks, the elements that are assembled to build a building. Different materials have different impacts on the Earth. Some require extensive resources for their manufacture. Steel and other metals need to be refined from ore and processed into their final forms, often several operations, all taking great amounts of energy. The choices that go into selecting building materials have long range ramifications in a number of ways.

The materials we use in our buildings have an enormous impact on the Earth. Choosing materials with a lower impact can be an important criterion, but the matter needs to be looked at with proper long-term perspective. Careful use of materials with a long useful life (rather than materials which merely stick around for a long time after they have reached the end of their useful life, like vinyl siding) can result in a building that serves generations. Densities of use found in modern cities are only realistically possible when using higher impact materials such as steel. However, the offsetting benefits coming from the use of those materials helps to make this a more reasonable choice.

Buildings, according to calculations done by Architecture 2030, are responsible for nearly half of the total energy consumption in the United States. And 76 percent of the electricity generated in this country goes to the Building Sector. So while there are a range of steps that need to be taken in moving toward a more sustainable lifestyle, Buildings, and the energy they consume, need to be at the forefront of any considerations when moving toward greater sustainability.

Saving energy in buildings is both one of the easiest things that can be done, as well as one of the hardest. The principles for creating a building that needs less energy and operates more efficiently are well known. Most building technology is fairly basic and easy for even non-experts to understand. This makes it simple. We don’t have to wait for expensive, high tech solutions (though they can contribute greatly and will provide new flexibility and compelling possibilities for building better buildings in the future). Heavily insulated buildings can be easily constructed with readily available and well known technology. Adding more insulation to walls is easy, though there is a cost. Consumers and building owners need to become more aware of the long term costs of operating a building, and give consideration to more than just the initial construction costs. And overcoming economic considerations and taking a long-term view is the hard part.

Ypsilanti, Michigan is in the outlying suburbs of Detroit and is, itself, a city with a long automotive heritage going back to the Tucker Torpedo and Kaiser Motors and extending to a present day Ford assembly plant and the last Hudson dealership in the country and an Automotive Heritage Museum. But now, a local couple have embarked on a different direction towards automobiles, encouraging drivers to embrace a new mindset with a website called DriveSlowly, which they are unveiling for Earth Day.
