Their efforts take on a special poignancy with the start of yet another hurricane season (it officially began on June 1, though the tropical system Arthur formed a day early around the Yucatan Peninsula). With lingering La Niña conditions and water temperatures in parts of the Gulf of Mexico already a degree or two above average, there’s reason to be concerned.

The city of Greensburg KS was nearly obliterated by an F5 tornado in May 2007. But turning the devestation into an opportunity, the city is looking to make its mark by rebuilding as a green community. The city has mandated that all city buildings larger than 4,000 sq. ft. must be built to LEED-Platinum level and must have an energy performance level at least 42% better than current building code requirements.

“The city of Greensburg has taken the extraordinary step of committing to rebuild their community to a new vision, not settling for simply recreating what had gone before,” said Rick Fedrizzi, President, CEO & Founding Chair, U.S. Green Building Council. “By committing to a recovery plan based on green building, the community’s leadership has set a path that will result in a healthier, more livable city for its citizens, turning a crisis into an opportunity that is an example for us all.”

After a disaster, it is difficult to take the time and effort to try to build something better than what had been present before. This mandate only applies to city buildings. But hopefully, the wider city itself will embrace this direction, and not only will city buildings, but the stores, offices, homes, and other buildings will likewise be built better, and greener, than what they are replacing.

This portable, self-powered water and sanitation station has many sustainable features, including a composting toilet, rainwater collection and filtration system, and solar panels that, along with a battery, provide all the power the Clean Hub needs and then some. The idea came from folks at Shelter Architecture, but thanks to architecture and design students at the University of Minnesota, it will soon be put to use in New Orleans, where it will be the centerpiece of a community that will foster sustainable growth.

John Dwyer from Shelter Architecture, who also led the students in designing a prototype of the Clean Hub, describes the project:

Shelter developed the idea through a 2 year research and development process. We then brought it in to a studio to allow students to design and build a real world application of it.

The hub is totally off-grid, generating its own water through rain water collection, it's own electricity through photovoltaics, and its own sanitation through composting toilets and gray water irrigation.

The first prototype heads to a learning garden in the hardest hit area of New Orleans on June 21st, the summer solstice.

The architecture students at the University of Minnesota took the concept and ran with it, creating a low-cost solution based on a used storage container that can be easily transported to disaster-stricken areas to provide necessary infrastructure. It was built using recycled and donated parts, lots of elbow grease, and a green vision. The Clean Hub is a simple solution to a complex and common problem that is certainly more practical and sustainable than what FEMA currently uses!

The Clean Hub will be sent to the Lower Ninth Ward in New Orleans, and will serve as a building block to a sustainable rebuilding effort supported by many local organizations. A community garden, farmer's market, and public gathering space will eventually surround it, leading to urban renewal with sustainability in mind.

Hopefully with the success of the Clean Hub in New Orleans, the idea can be continued to help provide water, sanitation, and renewable energy wherever it is needed around the globe. The design was created with urban slums and refugee camps in mind, both possible future homes of the Clean Hub.

This design encompasses cradle-to-cradle thinking, sustainable development, poverty relief, and community building as well as green design. It's not every day that architecture is used to save the planet and help the poor, but the Clean Hub was an opportunity for architecture professionals and students to do just that.
