The 20 teams selected for the 2009 Solar Decathlon have been announced by the US Department of Energy. Each team will receive a $100,000 grant from the DOE to be used for creating a completely solar-powered home for the competition.

The full list can be found in an article at Custom Home Online. The 2009 competition has some international flavor, including last year’s winner, the Technische Universität Darmstadt, as well as the Universidad Polytécnica de Madrid and two groupings of Canadian universities.

Like other wonders of the modern world, these amazing green wonders are places you must see before you die. These structures are unique in the world for their brilliantly creative methods of melding aesthetic beauty, functional design and environmental sustainability.

Built in Darmstadt, Germany, this structure is called Waldspirale or “Forest Spiral.” It was designed by Friedensreich Hundertwasser, a celebrated Austrian architect and painter. Planted along the 12 floors of the rising roof are beech, maple, and lime trees. The structure even incorporates a running stream. The building comprises 105 apartments. In the tower on the Southeast corner, a restaurant and cocktail bar rises over the entire structure. Source: Wissenschaftsstadt Darmstadt.

Nestled in Pembrokeshire, in Southwest Wales, this structure is truly an eco-dream home. It was built about three years ago by a single family and their friends over the course of four months. The family estimates that it took about 1,000 to 1,500 hours of work and cost only about £ 3,000. It was constructed mostly out of logs, straw and mud, which acts as an effective insulator. According to the house’s inhabitants, the home “feels gentle. Feels to me more like being part of the (natural) world, less like a commodity in a box.” Source: Simondale.

The Association of Collegiate Schools of Architecture (ACSA) and the Portland Cement Association (PCA) have announced their “Concrete Thinking for a Sustainable World” student design competition.

This is the third year for the competition. The concrete industry is looking for opportunities to boost the perception of concrete as a green material, since the mining, processing and transportation of concrete is responsible for 8% of all carbon dioxide produced by human activity.

This is the first of our Guest Posts through the Green Options network. Jason Phillip is a freelance writer and editor based in Chicago. He writes about the “green scene” in the Windy City for Sustainablog.

The urban fabric of Chicago is getting greener every year. Since 1989, more than 500,000 trees have been planted, more than 80 miles of landscaped medians constructed, and 2 million square feet of green roofs built or negotiated—more than all other American cities combined. But the more significant greening is happening in the built environment, where sustainable architecture is becoming a growing part of the skyline here in the birthplace of the skyscraper.

The push toward green building has been gaining momentum in the Windy City during the past few years. Chicago served as proud host to the 2007 GreenBuild Expo in November. The city already has the most LEED-certified buildings in the world. In the private sector, a number of large commercial projects underway will showcase some innovative design. One of the most dramatic of these is Santiago Calatrava’s Chicago Spire, a 2,000 foot twisting tower that will become the nation’s tallest building after completion in 2010. The commercial and residential tower will seek LEED Gold status based on many features including special glass to protect migrating birds.

Part of the reason green building is gaining momentum is a big push from City Hall. The administration of Mayor Richard Daley has mandated the use of green roofs and other sustainable design in all city-financed projects. While commercial developers gradually find their way to building more sustainable design as the real estate market develops demand, the city has been able to spread green building throughout the city by requiring all new public buildings to achieve LEED Silver status. In addition to the creation of green schools, green police stations, and green libraries, two buildings that opened their doors this year to some of Chicago’s poorest residents show that green design isn’t just for the well-heeled.

The California Energy Commission asked the Davis Energy Group in Sacramento to evaluate new home construction in California a few years ago. The following excerpt from Home Energy Magazine tells you what they found.”The increasing architectural complexity of new homes requires greater vigilance on the part of framers, insulators, and drywall contractors to create a single thermal/pressure boundary between conditioned and unconditioned spaces. The more complex the design of the home, the [...]

Wildfires aren’t usually on my radar, because I don’t live in a region that is much susceptible to them. But, in the past couple of weeks, everyone has become more aware of them. They have been widely across the news because of the number of serious wildfires in southern California recently. At the same time, recent news coverage has also looked at drought conditions which are being felt in Georgia

Efficient materials can sometimes seem to be the ideal path for green building. If we can find a way to more efficiently produce the materials we need to build our buildings, it would seem that we would be well on our way to reducing our impact on the planet.

For example, rather than using lumber sawn from old growth forests, engineered lumber and I-joists make more efficient use of lumber resources

"Was it a conscious decision or a momentary lapse of reason? How did progress take priority over humankind? Could harnessing the world’s energy that allowed our ascent now be the ledge pan of our down fall?" These are the questions addressed in the PBS ongoing series e2. The most recent episodes, narrated by Morgan Freeman, focus on energy. They look at transportation infrastructure, the auto industry, fuels and renewable fuels, alternative

For all our technological advances, our buildings remain incredibly dumb constructions. Automobiles have multiple onboard computers that help maximize their performance and improve efficiency and coordinate the various systems. But the average house has very little, if any, control to aid in its operation despite the wide range of conditions (from below freezing winter nights to scorching summer days) they are forced to deal with. Even large, complex buildings operate with

Sustainability is making its way into mainstream periodicals. It seems like almost every magazine in the past year has featured a "green" issue, some credible, some not. My friend just gave me the green issue of a magazine targeted at the marketing industry. So it’s no surprise that Edutopia, an education magazine for teachers and administrators published by the George Lucas Educational Foundation, used sustainability as a theme for their
