Enter the second year of the Lifecycle Building Challenge competition, to shape the future of green building and facilitate local building materials reuse. Submit your innovative project, design, or idea for reducing to conserve construction and demolition materials and reduce greenhouse gas emissions by designing buildings for adaptability and disassembly.
Lifecycle building is designing buildings to facilitate disassembly and material reuse to minimize waste, energy consumption, and associated greenhouse gas emissions. Also known as design for disassembly and design for deconstruction, lifecycle building describes the idea of creating buildings that are stocks of resources for future buildings.

create designs that facilitate local building materials reuse

consider the full lifecycle of building materials — design through deconstruction and reuse

focus on quality and creativity of designs and concepts

develop strategies that maximize materials recovery
 reduce the overall embodied energy and greenhouse gas emissions of building materials through reuse
 decrease environmental and economic costs

address real world issues
Key Challenge Guides and additional resource materials are available at www.lifecyclebuilding.org/resources.htm
