This is the second year of the Lifecycle Building Challenge, which awards prizes for innovative projects, designs, or ideas that reduce or conserve construction and demolition materials and reduce greenhouse gas emissions. Local building materials use and designing for adaptability and disassembly are rewarded. It has categories for professionals, students, and a "people's choice" category, and is awarded to both buildings and building materials. Haworth won the "People's Choice" category in 2007 for its successful "unbuilding" of its corporate headquarters, during which a whopping 75% of the materials were donated, re-installed, or recycled. Shown here is the Bioshelter Leaf Project:
"This structure is a prototype for a studio, office, cabin, greenhouse, workshop, garden shed and Bioshelter. It may be disassembled and re-built at another location or dismantled for recovery of components. There exists a full size prototype with an opaque, insulated roof."
