SAN FRANCISCO – During a ceremony at the West Coast Green Conference in San Francisco, U.S. Environmental Protection Agency Office of Solid Waste and Emergency Response Assistant Administrator Susan Bodine announced winners of the inaugural Lifecycle Building Challenge competition.

U.S. EPA Assistant Administrator Bodine, along with the American Institute of Architects President RK Stewart, and Building Materials Reuse Association President Brad Guy, recognized award winners for their cutting-edge green building ideas that aim to reduce environmental and energy impacts of buildings.

Ideas from the design contest will jumpstart the building industry to help reuse more of the 100 million tons of building-related construction and demolition debris sent each year to landfills in the United States.

“Reusing valuable building materials conserves resources and reduces greenhouse gas emissions,” said Bodine. “Designing buildings for adaptability, disassembly and local reuse is an important environmental protection strategy.”

The “Lifecycle Building Challenge” – partners the U.S. EPA, the Building Materials Reuse Association, the American Institute of Architects and West Coast Green – invited professionals and students nationwide to submit designs and ideas that support cost-effective disassembly and anticipate future use of building materials. Green Building Blocks, the competition sponsor, provided cash awards to student winners, and Green Building in Alameda County, Calif. provided the awards.

Lifecycle building maximizes material recovery to reverse the trend of disposing of large quantities of construction and demolition debris in landfills. Reusing building components also reduces energy and greenhouse gas emissions associated with producing and transporting materials.

In the United States, buildings consume 60 percent of total materials flow (excluding food and fuel) and account for 33 percent of the solid waste stream. Building renovation and demolition accounts for 91 percent of the construction and demolition debris generated each year, while new construction accounts for only 9 percent. Between 2000 to 2030, 27 percent of existing buildings will be replaced and 50 percent of the total building stock will be constructed.

These issues can be addressed by planning for a building or building component's eventual deconstruction or adaptation. By creating building components that can be easily recovered and reused, materials are kept at their highest value, resulting in reduced consumption of energy and resources.

The challenge grew out of a project that the EPA helped fund at the Chartwell School in Seaside, Calif. that demonstrates lifecycle building concepts. The school tested new systems including nail free paneling, centralized utility raceways, structural insulated panel roofing, and cold joint sidewalks that can be easily moved for reuse. Results from Chartwell's case study are available on the challenge's Web site.

The challenge, open to built and un-built work, was launched in January and open for four months. The categories include:

· Building—an entire building from foundation to roof
· Component—a single building assembly, system, or connector
· Service—a tool, method, or other idea

The winners, selected by a panel of expert judges, are listed below and include contact information:

Pavilion in the Park (Professional – Built)
David Miller, architectural designer, The Miller|Hull Partnership, Seattle, Wash.
Building that separates into four modules and can be moved by truck
The 11,100 square foot Pavilion in the park’s entire structure is designed for future transportation, reassembly and reuse in a new location. The building’s parts separate at three integrated joints to break into four separate modules that can be moved on trucks by surface street. The building sits lightly on the land atop short concrete piers allowing the grade and vegetation to run uninterrupted beneath. Gangway ramps with integrated hinged joints allow the ramps to adapt to the topography of future locations. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=35

The groHome (student)
Adam Fenner, Jason Bond, Thomas Gerhardt, Josh Canez, Nick Schaider, students, Texas A&M University, 2007 Solar Decathlon Team, College Station, Texas
Open source housing modules to meet changing family and community needs
The open source concept used in the software community is adapted in this entry to develop open source building systems allowing anyone to design and incorporate elements into the building system if grid protocols and standard joint connections are used. Using a library of pre-manufactured components brought to a site and assembled efficiently, the structure is designed with a specialized bolted connector joint that allows for components to be unplugged easily and without damage. Radio Frequency Identification Tags (RFID) can be embedded to take inventory and check the history of components. The project includes a community building game, Utopia 2.0, to allow neighbors to swap building modules as family and community needs change. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=84

Sustainability by Design: Deconstruction and Adaptive Reuse (People's Choice Award)
Mitch Boucher, Haworth, Inc., Holland, Mich.
Comprehensive 99 percent reuse and recycling construction project
When Haworth, a global designer and manufacturer of adaptable workspace environments, planned major renovations on its headquarters, the company set a goal to recycle or salvage up to 75 percent of the materials. The project diverted more than 99 percent of construction materials through reuse and recycling: 321 tons of steel were recycled; 75 workstations were donated; and door locksets were removed intact and reused in other facilities. More than 58,000 tons of carpet tiles were removed for re-installation, donated to local schools, or recycled.

Green-Zip-TapeTM Demountable Tape (Professional - Built)
Frank Little, founder, Tax Advantage Design, Magnolia, Texas
Drywall tape attachment system to support easy deconstruction and reuse
Patented demountable tape provides an alternative method for hanging sheetrock for later de-construction and reuse. Drywall has traditionally been a barrier to gaining easy access to structural components of the building for repair or reuse. This tape and associated screw connectors allow drywall to be easily removed and replaces the traditional nailing mechanism, which can damage the drywall and inhibit reuse. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=90

Deconstructable and Reusable Composite Slab (Professional – Unbuilt)
Mark D. Webster, Dirk M. Kestner, James C. Parker, Matthew H. Johnson, structural engineers, Simpson Gumpertz & Heger, Inc., Waltham, Mass.
Reusable structural floor system
The composite component system uses specialized bolts, serrated clamps, and cast-in channels to create a more easily disassembled system, allowing reuse of the composite slab. A serious problem with conventional composite slabs is that it is a "throw-away" system; most of the parts are completely non-reusable at the end of the building's life. The team developed a composite slab system that maintains the efficiency benefits offered by composite action, while adding near 100 percent reusability. The structure allows the slab and beam to work together to resist bending due to floor loads. The size of the steel beam can be reduced by over 30 percent providing both economic and environmental benefits. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=46

Guidelines for Building with Reusable Materials (Student)
Aaron Tvrdy, University of Nebraska, Lincoln, Neb.
Creative designs from reused building materials collected regionally
This project foresees waste materials gathered in bulk, refurbished, and stored in regional design centers where designers can create components out of former waste. One example uses discarded railroad track and ties to create a superstructure for a wood pallet wall system. With a creative design approach, reclaimed material kits can be used to create attractive components that can either celebrate or conceal their original identity. http://lifecyclebuilding.org/gallery-detail.php?EntryID=56

Deconstruction Engineer (Student)
Keith Cullum and Paul Sargent, California Polytechnic State University, Yorba Linda, Calif.
Proposed new profession to support building deconstruction
The project proposes a new degree program and profession: the deconstruction engineer. These professionals would consult throughout a building’s lifecycle to ensure that adaptation and deconstruction occur in the most effective way. During the first stages of planning a structure, the engineer offers design suggestions to anticipate efficient deconstruction. At the end of a building’s life, the deconstruction engineer evaluates and assesses safe reverse construction procedures for salvaging materials. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=75

Modular 3
Dan Rockhill, Studio 804, University of Kansas, Lawrence, Kan.
Flexible single family home with movable walls
This two bedrooms and one bath residence uses all of the 1,200 square foot of living space that is composed of six modules. The proportions of Modular 3 have been tailored to dimensions of a standard city lot, and a raised pier foundation allows for low-impact implementation in nearly any single-family residential context. A movable storage wall permits splitting an area such as a single bedroom into a separate office and storage space at the homeowner's whim. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=74

Re-use of Cleveland Iconographic Structure
Dru McKeown, TOI Studio, Lakewood, Ohio
Transit stations and street furniture made from a building façade
Instead of creating new building systems, designs for bus and light rail transit stations and street furniture were created out of the façade of a building slated for demolition. The project recaptures the materials and embodied energy that were spent creating the initial structure. The entrant calculated that the average building’s embodied energy is equivalent 10 – 15 gallons of gasoline per square foot and that materials in an average American home have embodied energy equal to 29.25 autos weighing 1.5 tons. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=81

Transformative Multi-family Housing
Koji Saida, Mimi Sullivan, Hyun Joo Choi, Keiko Ito, architect, Saida + Sullivan Design Partners, San Francisco, Calif.
Shape shifting residential and office space
The transformative multi-family housing is a mixed use project with 12 residential units and one retail space on the ground level. By standardizing all the building components and using a simple connection system, the entire building's components can be easily deconstructed, reused and recycled. By exchanging some standardized wall panels, a 2-bedroom unit transforms into a 3-bedroom unit and by removing all non-bearing walls, the three residential units that are grouped as typical can be transformed into office use. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=17

Joist Lock
David Wilson and Michael Kozel, engineer, AVAVA Systems¸ LLC, Berkeley, Calif.
Rigid wood connecting system alternative to conventional framing
The joist-lock component is a strong, reusable alternative to conventional wood framing. This patent-pending device connects manufactured wood I-joists intersecting from two different planes and locks, creating rigid connection at the intersection. The rigid connection creates a force-resistant frame out of the wood shell of a building, eliminating the need for braces or shear walls to support the shell against wind and earthquake forces. The joist lock creates a rigid tube that can span from end to end, eliminating the need for continuous foundations used in traditional construction. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=61

Expansive Panel System
Sean Dorsy, Catholic University of America, Washington, D.C.
Reusable, waste reducing alternative to traditional wood framing
Inspired from the efficiency of pizza boxes, the Expansive Panel System [EPS] is an alternative to traditional wood framing. EPS uses Digital Fabrication and Computer Numerical Controlled machinery to fabricate with minimal material waste while allowing for a simple assembly using precise components. The EPS has a "zig-zagging" pattern that allows panels to expand from a single sheet of plywood without added fasteners, which conserves material, time, and money. A projection comparing the EPS to traditional light-frame construction found a cost savings of $597 and material weight reduction of 4,406 pounds. These components are also designed for disassembly and for reuse in future structures. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=88

Low-tech Pre-fabricated Structural Building System
Siobhan Rockcastle, Cayley Lambur, Dana Cupkova-Myers, and Kevin Pratt, Cornell University, Ithaca, N.Y.
Flexible, recyclable cardboard and foam dome structure
The flexible dome shaped system uses laser-cut recyclable cardboard, high-density polystyrene foam, and a waterproof fabric membrane, which can be separated, readapted, and recycled as needed. The basic bracing structure can be sequentially erected very quickly: pre-fabricated cardboard bracing is folded along seams; waterproof glue with a catalytic release is applied to lower ridges of the bracing; hexagonal/triangular lightweight foam panels are then adhered; and a compressible foam rod is inserted between panels to eliminate the need for sealant.

The Nail Extractor
Jeff Wagner, The Nail Extractor, Charleston, S.C.
Nail and staple removal tool eases building disassembly
These extracting pliers were invented to aid in building restoration and renovation by removing fasteners without bending or cutting the exposed materials. During a renovation or salvage project, the amount of fastener removal that is required can be extensive and time-consuming. Though the nail extractor was originally designed to pull brittle older nails, it can also remove modern-day pneumatic nails and staples, with their slender shanks and undersized heads. The tool allows for easy, single-handed operation, using jaws that exert increasing gripping pressure in proportion to the resistance encountered during extraction. http://www.lifecyclebuilding.org/gallery-detail.php?EntryID=44

Promoting Reuse of Building Materials While Protecting Public Health
Jennifer Voichick, Habitat for Humanity of Dane County, Madison, Wis.
Proposal to examine lead-paint building material reuse options
This project explores options to divert building materials with potential lead-paint hazards from landfills in a manner that is both environmentally responsible and addresses public health concerns. Under Wisconsin state law, all items with paint or other coatings produced before 1978 are presumed to present lead hazards unless tested to prove otherwise. The proposal would identify alternatives to landfills that allow reuse of materials with lead-based coatings and address concerns about lead poisoning that could serve as a national model for other businesses promoting reuse of building materials. http://www.lifecyclebuilding.org/entries/106316text.htm
