The EPA recently honored six innovative green concepts designed to reduce the environmental and energy impacts of buildings. These concepts may assist the building industry in reducing more than 88 million tons of building-related construction and demolition debris sent to U.S. landfills each year.
The EPA awards recognized student and professional designs for buildings and building projects, as well as special categories, including the creation of green jobs.
“Designing buildings and building products with front-end lifecycle thinking is the key to real green building,” said Lisa Heinzerling, associate administrator for EPA’s Office of Policy, Economics, and Innovation. “These innovators are great examples of how we can build sustainable structures that help meet the needs of this and future generations.”
Lifecycle building is designing structures 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 high-performance buildings today that are stocks of resources for the future. EPA recently reported that doubling the reuse and recycling of construction and demolition debris would result in an emissions savings of 150 million metric tons of carbon dioxide equivalent per year, equal to the entire annual carbon emissions from the state of North Carolina.
EPA, along with its partners, the American Institute of Architects, West Coast Green, the Collaborative for High Performance Schools, and StopWaste.Org, invited professionals and students nationwide to submit designs and ideas that support cost-effective disassembly and anticipate future use of building materials. The competition was open to architects, reuse experts, engineers, designers, planners, contractors, builders, educators, environmental advocates and students. This year, the competition was extended to include international participants who hailed from Singapore, Taiwan, Argentina, Columbia, France, Egypt, and the United Kingdom.
US WINNERS
Student Building
[Un] Modular Design for Deconstruction
David Fleming, University of Cincinnati, Richfield, MN
This construction trade school design redefines "building" as a temporary resting place for materials to be traded, upgraded and reused. The project shows the potential for a building to evolve with time as materials, fashions, technologies, and uses change. The adaptable structural system can create almost any column, beam and wall configuration. Rather than attempting to find an infinitely reusable module, the project creates a framework for creative materials reuse.
Professional Building
Arboretum and Research Visitors' Center
Kira Gould, William McDonough + Partners, Charlottesville, VA
The visitors' center design roots the building firmly in its woodland context by blurring distinctions between the indoors and outdoors, and by incorporating the surrounding forest into the building's lifecycle analysis. Construction emphasized safe, closed material loops of biological nutrients, which break down to safely return to forest soil; and technical nutrients, which can be remanufactured into new objects. The mechanical connections and reconfigurable modules allow for building alterations. The project performs 51% better than the ASHRAE-compliant base case used to measure the greenhouse gas reduction.
Professional Product
Modular Temporary Construction Wall/Barricade
Douglas Spear and Aaron Barnes, ENVY Modular Wall Systems LLC, Las Vegas, NV
This modular temporary construction wall system consists of panels and extruded joining parts that are recyclable, reusable and can be recycled into new products with zero waste. It replaces wall systems that are used for a short period of time (1-18 months) and often end up in a landfill. Replacing conventional materials used to create temporary walls saves approximately 1 ton of material from the landfill per 70 linear feet of standard height wall. The modular temporary construction wall system is being used in the MGM Mirage City Center Project in Las Vegas, Nevada where it will conserve over 100 tons of construction debris.
OUTSTANDING ACHIEVEMENTS AWARDS
Best School Design - Sponsored by the Collaborative for High Performance Schools
School M.O.D.
Yosuke Kawai and Ikue Nomura, University of Pennsylvania, Dayton, OH
This prototype school building focuses on feasibility and maximizing flexibility. The usual constraints of fixed areas are resolved by combining modular (M), open (O), and dual structural (D) systems. This construction technique allows any individual to build with locally available materials to meet immediate needs while providing the opportunity for future growth.
Best Green Job Creation
ReAnimateLA: Center for Ecological & Urban Recovery
Hayley Stewart, Cal Poly Pomona, Pomona, CA
ReAnimate LA would create up to 100 green jobs maintaining the sustainable elements of the building, such as the extraction and reuse of salvaged materials in construction, photovoltaic and ground-source heat pump systems, and bioremediation planting. ReAnimate LA speaks to the changing public values on environmental policy and the urban networks that are essential in bringing back value to a localized, organic way of life in the American city.
Best Greenhouse Gas Reduction - Sponsored by the American Institute of Architects Committee on the Environment (COTE)
Arboretum and Research Visitors' Center

HONORABLE MENTIONS
Political Ply - An Arid Zone Shade Structure
Jason Griffiths, Arizona State University, Tempe, AZ
Political Ply explores methods of re-purposing existing political campaign signs to form a temporary arid-zone shade structure. The structure is composed of hexagons and each cell has a self contained cooling structure. The project is designed for disassembly, and each hexagonal cell is tapered to allow cells to stack together for convenient transportation.

Professional Building
Reclaimed Space: Sustainable, Modern
Zak Hardage, Tracen Gardner, and Kimber Reed-Barber, Reclaimed Space, Austin, TX
This modern, sustainable designed home values reclaimed materials that are the product of disassembly. The average home generates 8,000 pounds of waste, 80% of which is recyclable while Reclaimed Space homes create less than 300 pounds of waste, nearly all of which is recycled. These energy sipping homes feature solar and rain catchment systems, recycled newspaper insulation and reclaimed 100-year old hardwood oak flooring.
INTERNATIONAL WINNERS
The Worm Bar
Miaoling Li, National University of Singapore, Singapore
The Worm Bar integrates a worm farm, salad bar, and educational gallery into a temporary pavilion structure. More than 90% of the pavilion components come from the adaptation of an existing scaffolding system that can be easily disassembled for use in other projects. Highlighting the processing of our waste by humble earthworms, the pavilion aims to increase the awareness of consumption patterns, and provoke discussion on alternative methods of waste management. The project even envisions visitors leaving with a souvenir bag of vermicompost!
INTERNATIONAL HONORABLE MENTIONS
Carapace Communion
Rhys Owen, University Of Westminster, United Kingdom
The Carapace Communion project celebrates disassembly by investigating the relationships created when a community's need for a sheltered meeting space results in the creation of a stronger and more environmentally aware society. Each communion member owns a construction component, but only when multiple elements are assembled (through use of removable fasteners) can a functioning structure be created. These structures can be disassembled to give each member their element back and the structure can be assembled, disassembled or adapted very quickly.
CLOTHed PAVILLION
Hui Ying Lim, National University of Singapore, Singapore
This temporary pavilion of recycled compressed clothing challenges the limitations of an abundant source of recyclable cloth, by converting it into architectural components. Fabrics currently have very low recycling rate -- 12% in Singapore. Re-purposing fabric heightens environmental awareness and would result in 169,000 sets of clothes (230 tonnes) being reused. The cloth bales are starched hard and treated for additional strength, and can be de-starched without damaging the material. The pavilion uses standard wall modules to create partitions and furniture that can be easily reconfigured.
Garden Toilet
Caijin Huang, National University of Singapore, Singapore
This is a small project designed as a temporary "public convenience" structure to provide the public with bathrooms and showers at on-site events. The walls are tall enough to provide basic privacy. The structure's hollow walls can be filled with natural materials (fallen leaves, pebbles, stone) or reclaimed materials (bottles and cans). The shower screens are made of layers of overlapping of bamboo to maximize privacy while creating openness and ventilation. The building can be taken down easily and some of the materials can be returned to nature.
