136 million tons/year

Construction 9% Demolition 53% Renovation 38%

C ONSTRUCTION T RENDS

• 27% of existing buildings will be replaced between 2000 and 2030 •

50% of buildings in 2030 will have been built since 2000

• Adaptability - Most buildings are demolished because of changing needs, not because they wear out

L IFECYCLE B UILDING C HALLENGE

Shape the future of green building and facilitate local building materials reuse.

Submit your innovative project, design, or idea for reducing construction and demolition materials and greenhouse gas emissions by designing buildings for adaptability and disassembly.

Lifecycle building is the design of building materials, components, information systems, and management practices to create buildings that facilitate and

anticipate future changes

to and eventual adaptation or dismantling for recovery of all systems, components, and materials.

• Lifecycle building links to

conservation energy

and reduces

greenhouse gas

emissions

Transporting

building materials consumes energy and produces carbon-dioxide (CO2)

extraction + manufacturing + processing + packaging + transportation + recycling + disposal

= embodied energy

Lifecycle Building Challenge 2007 winner:

Michael Berk professor at Mississippi State University GreenMobile

TM Lifecycle building reduces embodied energy over a material’s life by: • reducing transportation by creating local stocks of materials • minimizing extracting and manufacturing energy by reusing materials • avoiding disposal energy and cost
