Waste recycled through architecture

What do you think of such recycling approaches?

http://www.bing.com/videos/watch/video/house-built-using-6-million-bottles/ufb2lfqq

Points to think about:
. is waste material to be the resource for new construction?
. is this your preference for future form,texture and material of our cities and your house?
. is emphasis on such re-use and recycling methods detracting us from the "reduce and regenerate" principles of sustainability?

Unforgetting Adobe. BRICK 2010 Award

BRICK AWARD 2010
PRESS RELEASE 8 April 2010
Hannover D | Berlin D | Knoxville Tennessee USA

Hansjörg Göritz is the prime laureate of the prestigious international Brick Award 2010.

....In this way the undisputed role of bricks is acknowledged and celebrated as an timelessly esthetic, sustainable and ecological building material. In Liechtenstein this year's prime award for the Principality's new State Capitol Forum and Parliament, Professor Göritz' architecture provides state legislature an architectural materialization of its own for the first time in its bicentennial history since its sovereignty in 1806. Following the success of the HansjörgGöritzArchitekturstudio in an invited international European competition of the year 2000, seven years of planning and implementation were completed with its grand opening ceremony in early 2008. Today the built exterior and interior spaces manifest not only his interpretation of democratic separation of powers within the Alamannic cultural region of the Alps' Rhine River valley. They also stand for a conscious understanding of an architecture of urban contiguity, whereby the original masterplan of renowned Luigi Snozzi has been newly reinterpreted. At the same time the pure and meticulous materialization of the new context rejects generic easy conventions, and strive for an architecture of space and timelessness. It is this very elementary and sustainably durable quality that makes use of non-renewable resources according to rigorous Swiss Minergy-Standards. The materiality and consistency is truly enchanting, achieved through the use of exclusively bright yellow ochre brick, baked from Jurassic clay. 680,000 specially customised bricks totally cover all pavings, floors, walls, ceilings, and even roofs. The warm light that reflects off the surfaces of the bricks creates a special atmosphere both inside and outside the buildings, thus creating a unique modern place deeply rooted in its European tradition to be remembered.

Straw: Ideal Building Material?

The Economist writes that straw buildings may be making a comeback, even if use of the material breaks local building codes. Straw may be an ideal building material for some types of buildings– it can be embedded with other materials to create adobe or stucco. It’s a great insulator. It’s often a waste material so can be recycled for low-cost. Additionally, straw buildings are highly earthquake-resistent because the material is inherently flexible and absorbs seismic energy better than steel, brick or glass.

In some areas, the benefits of using straw may not be realized because local building officials prevent its use. The Economist points to Californian officials who recently tried to dump heavy fines on Warren Brush, owner of a non-profit farm, for building straw-bale buildings on his property. “The problem is that California’s building codes make no provision for the use of straw. And Mr Brush has many defenders—among them several university scientists and David Eisenberg, the chairman of the United States’ Green Building Council’s code committee.”

Perhaps with all the support from the USGBC, more local officials will see the utility of making low-cost earthquake-resistant material widespread. The Economist writes that straw has beaten other materials in earthquake tests. “A year ago, a test conducted at the University of Nevada’s large-scale structures laboratory showed that straw-bale constructions could withstand twice the amount of ground motion recorded in the Northridge earthquake that hit Los Angeles in 1994.”

It’s the combination of materials that make straw buildings highly resilient. Straw building begin with a foundation of gravel contained in plastic bags covered with soil mortar. ”The walls are made of tightly packed straw bales held together with bamboo pins and lined with fishing nets. These are then coated with a clay-based plaster. Aesthetically, the final product is similar to stucco or adobe.”

Complicated work can also be done with the material. One structural engineer was able to create a two-story, three bedroom house with the straw mix. Additionally, in areas where there aren’t rules against using straw, there’s been a growth in projects, including a new post office in suburban Albuquerque and a Quaker school in Maryland.
