One of the biggest problems with solar cells currently on the market is that they are extremely easy to break. Companies intent on manufacturing any sort of solar powered products have to find solutions, and few have yet been perfect. Hoping to change this trend, Dupont recently announced the launch of two new lines of encapsulants specifically designed to contend with the trials inherent in manufacturing photovoltaic products.
Technological innovations can solve some of the world’s biggest problems right? That’s what a firm of Chilean architects would like us to believe. They’ve come up with a creative idea for how land-locked Bolivia could regain access to the ocean. It was not too long ago, in 1883 to be exact, that Bolivia lost the little coastline it had in a war with Chile. Since it’s only be gone for a short time, now’s the perfect time to get it back!
Whenever I see my friend James D’Addio, the architectural photographer, I ask him about which new green buildings he’s been shooting. Not surprisingly, in a city with dedicated green building blogs and the NYC Department of Design & Construction’s award-winning programs, NYC may be the greenest city in the United States. Here two projects in NYC that exemplify where green building is going.
Norman Foster’s Hearst Tower, which sits atop a 1928 landmark building in Manhattan is engineered to use 25% less energy than required by code and boasts the world’s largest “air conditioner.” The two-story, stepped waterfall is also a huge radiant cooling system that along with other measures saves 1.7 million gallons of water every year. Other interesting facts about the building include:
And without the chickens, Derek Hoeferlin and his architectural students from Washington University would not have had reason to take interest in this little community garden which has begun to harbor interest for it’s uniquely designed “urban chicken coop”, the story of its recovery post-Katrina and the sustainability recipe it holds for other communities across America.
Though green roofs are reemerging in the most advanced building designs around the world, for centuries, people constructed buildings out of materials immediately available to them in their surrounding environment. It is only a relatively recent luxury, for example, that people have easy access to roofing materials like asphalt shingles made hundreds, perhaps, thousands of miles away.
On the island of Læsø, Denmark there still stand a handful of buildings that are excellent examples of what communities would do with what was immediately available to them — if only they had any of it left.
In the Middle Ages the island of Læsø became famous for its salt industry. Hundreds of salt kilns were built, throughout the island, requiring constant fuel for the important final stage of commercial salt concentration. But on the island of Læsø—a community with a finite availability of natural resources—constantly feeding the hundreds of salt kilns eventually led to the island’s deforestation.
Under recommendations from the UK Green Building Council, otters could return to urban rivers, bats could roost under bridges, swifts could flock to office blocks and peregrine falcons soar above cathedrals.

They are all at the vanguard of a move to encourage biodiversity in buildings that could take on an unprecedented scale if guidelines published today are adopted.
There may be few occupations that have more opportunity to incorporate sustainable choices into their products, services, and day-to-day operations than architecture. The market for green building has cooled down along with everything else, but it seems inevitable that it will replace its traditional counterpart faster than most other sustainable industries. Organic foods, for example, grew 20% year after year for almost a decade before slowing to a 6% growth in overall sales last year, but no one believes that organic will completely replace traditional agriculture anytime soon. Green building, however, may be lined up to become mainstream.
It just makes sense. Rising energy prices coupled with decreasing costs of many green building products and widespread acceptance of the many benefits of green building have produced a perfect storm that could realistically propel green building forward to mainstream acceptance. The other major influence is the economic downturn, which is bringing liquid clarity to the costs of maintaining a traditional home, and the corresponding benefits to planning for energy efficiency.

In an interview with TreeHugger, OpenSource designer Vinay Gupta had this to say:
“The idea that the U.S. might have to handle a city worth of refugees very suddenly shouldn’t be a strange thing to anybody who’s aware of the fact that there is some risk of terrorism on a mass scale. An organization like FEMA really has the responsibility to be able to evacuate a city worth of Americans in 24 hours if they have to be able to do so. That capability had not been developed so it couldn’t be deployed.”
Implementing Gupta’s emergency response plan and simple disaster shelters could develop that capability, working with FEMA, the Red Cross, and other local aid organizations.
Looking at the events surrounding the Katrina disaster, I’d say we really need to have a plan that works next time. The Hexayurt sounds like a phenomenal answer for sheltering displaced people, quickly. It’s a public domain project, OpenSource and ready to be taken to the next level.
Imagine houses with six feet-thick seaweed roofs, deep-nestled and hand-carved cave homes, and pigeon-harboring huts made of mud. Sounds a little unreal, huh? Well, this and more is all vividly documented in Built By Hand: Vernacular Buildings Around the World, a most inspiring bit of natural building eye candy I recently had the fortune of stumbling upon. Built by Hand is a hardcover collection of photographs of traditional buildings of all styles across the globe.
If you weren’t already appalled by the house design atrocity known as the McMansion, Built By Hand will make you pine ever harder for more intimate, natural, sensible, and green home designs that can be found all over the world, still being built by indigenous peoples and sometimes mimicked by enterprising, modern day natural home builders.
I happened to live in France back in 2002, and during my year there I noticed a pretty significant gap between sustainability as practiced in Europe in the US. In Europe, I was working with large public companies who were already integrating the implications of global warming and sustainbility into their businesses. In the US (and sadly still today), many companies were still arguing whether global warming even existed!
This difference was also evident in houshold products - from luxury hotels in Italy fully outfitted with CFLs to low-flow water fixtures and dual-flush toilets in many homes to small upright washers in even the most basic apartments, the kinds of products associated with our burgeoning US green movement today were already the norm in many parts of Europe back then.
On a recent trip overseas I happened to pick up a French architecture magazine for the flight home. I was pleasantly surprised to see that we had really caught up in the past six years - outside of being written in French, you would have been hard-pressed to distinguish this magazine from any of the leading US architecture magazines.
One article caught my eye, though, for it did point out a slight difference that needs to move across the pond. It was on a beautiful and practical prefab home, called the EvolutiV house by Olgga Architectes of Paris. The house itself is striking, made from two rectangular prefrabicated sections that can be rearranged to develop different floorplans and having exterior walls made from sections of wooden logs. The homes also come with the latest and greatest in eco-design: natural ventilation, rainwater collection, solar panels (both PV and thermal), green roof, radiant heating with an option for geothermal heating/cooling, and the typical eco-friendly materials throughout.
The most interesting piece of the story, though, is that the literature for the house and the articles written about it all refer to the home’s target energy usage: less than 48 kWh / m2 / year, which translates to about 4.4 kWh / ft2 / year. This is 70% less energy usage than the typical US home in similar climates.
It’s not the level of performance that makes this interesting, for many prefab options in the US can do as well. It’s that the media in France AND the architecture firm who designed the house feel compelled to advertise efficiency in terms of a single number that is easy to understand and can be used to compare this home to others one might choose. I’ve rarely if ever seen that in discussion of US prefab options (or other green homes) - outside of a LEED rating, we’re often left to guess exactly how eco-friendly that home is. We’d love to see this become more widespread in the US - information is power, and simple, objective numbers like this can help us separate the truly eco-friendly from innovative designs that are green in name (or advertising) only.
