With the green premise growing in popularity across the globe, more and more people are turning to cargo container structures for green alternatives. There are countless numbers of empty, unused shipping containers around the world just sitting on shipping docks taking up space. The reason for this is that it’s too expensive for a country to ship empty containers back to their origin. In most cases, it’s just cheaper to buy new containers from Asia. The result is an extremely high surplus of empty shipping containers that are just waiting to become a home, office, apartment, school, dormitory, studio, emergency shelter, and everything else. More information after the break.
   There are copious benefits to the so-called shipping container architecture model. A few of these advantages include: strength, durability, availability, and cost. The abundance and relative cheapness (some sell for as little as $900) of these containers during the last decade comes from the deficit in manufactured goods coming from North America. These manufactured goods come to North America, from Asia and Europe, in containers that often have to be shipped back empty at a considerable expense. Therefore, new applications are sought for the used containers that have reached their final destination.

On November 23, 1987, Phillip C. Clark file for a United States patent describe as a “Method for converting one or more steel shipping containers into a habitable building at a building site and the product thereof.” This patent was granted on August 8, 1989 as patent 4854094. The diagrams and information contained within the documentation of the patent appear to lay the groundwork for many current shipping container architectural ideas.
In 2006, Southern California architect Peter DeMaria, designed the first two-story shipping container home in the U.S. as an approved structural system under the strict guidelines of the nationally recognized Uniform Building Code. Even more impressive is Lot-Tek’s Puma City, which was built with abundant material at a low price, without substituting design quality. As such, there are many great examples of shipping container architecture in the world.

Shipping container architecture gets a lot of encouraging coverage in the design world as a trendy green alternative to traditional building materials, and seems like a smart choice for people looking for eco-consciousness. However, there are a lot of downsides to building with cargo containers. For instance, the coatings used to make the containers durable for ocean transport also happen to contain a number of harmful chemicals, such as chromate, phosphorous, and lead-based paints. Moreover, wood floors that line the majority of shipping container buildings are infused with hazardous chemical pesticides like arsenic and chromium to keep pests away.

Reusing containers seems to be a low energy alternative, however, few people factor in the amount of energy required to make the box habitable. The entire structure needs to be sandblasted bare, floors need to be replaced, and openings need to be cut with a torch or fireman’s saw. The average container eventually produces nearly a thousand pounds of hazardous waste before it can be used as a structure. All of this, coupled with the fossil fuels required to move the container into place with heavy machinery, contribute significantly to its ecological footprint.
Another downside is that dimensionally, an individual container creates awkward living/working spaces. Taking into account added insulation, you have a long narrow box with less than eight foot ceiling. To make an adequate sized space, multiple boxes need to be combined, which again, requires energy.

In many areas, it is cheaper and less energy to build a similarly scaled structure using wood framing. Shipping container homes makes sense where resources are scarce, containers are in abundance, and where people are in need of immediate shelter such as, developing nations and disaster relief. While there are certainly striking and innovative examples of architecture using cargo containers, it is typically not the best method of design and construction.

Green Cleaning at the University of Arizona

This is an excerpt from "Not just Clean, but Green" written by By Daniel Stolte, University Communications, July 20, 2011. To read more of the article, including specifics on what the University does to be green, visit: http://www.uanews.org/node/40727

The University of Arizona is one of only a handful of universities in the nation to receive Green Guard Certification from the Green Guard Environmental Institute for its sustainable cleaning practices.

Green custodial practices have earned the University of Arizona's Facilities Management Custodial Services team the Green Guard Certification, a recognition earned by only a handful of campuses nationwide.

"Together with our business partners, janitorial suppliers xpedx and Diversey, we have been working on being a green cleaning university for several years," said Christopher Kopach, director of Facilities Management. "When we looked at what other campuses were doing across the country, we realized we were already exceeding many of the requirements for certification, so we decided to go for it."

Kopach said that in 2008, when outgoing UA President Robert Shelton announced he wanted to make the UA a carbon-neutral campus, Facilities Management was already making the transition from "traditional" to "green" cleaning on campus.

The Green Guard Certification, given by the Green Guard Environmental Institute, is the formal recognition of the UA's commitment to maintain a clean, safe and attractive campus by conserving water, using only environmentally friendly sanitary and cleaning products and employing more efficient custodial practices.

Multifunctional Buildings by DRA&U

The design by DRA&U, which is meant to accommodate cultural activities, comes from the study of shells, their real geometry, neither ideal, nor platonic. The x-ray analysis of these slender bodies gave them the ability to perceive the deficiencies, deviations, and a set of slight imperfections due to environmental disturbances during development, which makes them so fascinating. Each shell contains history and a body that evolves with sublime patience, where the beauty, usefulness, functionality and aesthetics are linked to each other, because the amazing beauty lies not only in the outer (what you see usually), but also lurks in intimacy than hidden. More images and architects’ description after the break.

The building is generated by a continuous surface that conforms simultaneously limited space and connectively-distribution space. It is divided in such a way that allows to manage areas separately, among which are performance activities, shows, conventions, museums, sports, theatre and gaming zones. The outdoor area consists of paths, green areas, auditorium, playgrounds for children and an arena for outdoor events. The organic design of the flowerbeds, the walkways and squares must be read as a movement in space, never equal to itself.

The geothermal heart is another strong and important point of the project. The whole system is designed to disperse the minimum content of energy and self-regulating systems that take advantage of passive elements naturally bio-climate so as to minimize having the active contribution of primary energy production systems. In this perspective, optimization of overall efficiency of the system, is part of the further selection of innovative processes that use the low-enthalpy geothermal energy to produce thermal energy for air conditioning (which is not insignificant fraction of the total requirement) and that in turn are well matched with an energy of the generation of electricity from photovoltaics.

This choice has been stimulated by the geomorphological and hydrogeological configuration of the site, the site of productive aquifer where it was made on semi-confined appropriate analysis that would determine the potential environmental and human impact. In this case the low energy geothermal is used in accordance with the principle of aquifer thermal energy storage. All of these strategies helps to further streamline the process rather than using conventional geothermal systems.
