Orlando, FL (January 24, 2011)–CIMA joined forces with the APA (The Engineered Wood Association) in late 2010 to sponsor a competition challenging architects to design a home at or near carbon neutral. The APA Carbon Challenge Grand Prize Design Award was presented to Damon Roby of True Design Studios in Jacksonville, Florida. Roby and five other winners were recognized on January 13, 2011, at a ceremony sponsored by APA and CIMA at the 2011 NAHB International Builders Show in Orlando, Florida.
“The winners really put a lot of thought into the carbon footprint and operational energy of these homes, as well as proper design and constructability,” said APA Senior Engineered Wood Specialist Bob Clark. “If any of these six designs was built, it would have a positive impact on the carbon footprint of home construction today.” The winning designers included:
- Grand Prize Winner: Damon W. Roby, True Design Studios
- Second Place: Greg Beere and Jason Fisher, Content Design Group
- Third Place: Mark Straite, Mark Straite, Architects, Inc.
- Best Use of Wood: David Pillsbury AIBD, Keesee and Associates, Inc.
- Best Curb Appeal: Russell Ervin, Ervin Lovett & Miller
- Most Cost-Effective: Nicholas Renard, Cote Renard Architecture
Roby’s design featured beautiful historic Florida architecture and excellent interior living space. The design included a raised wood floor with a closed conditioned crawl space and advanced framing, including 2×6 wood framing with wall studs spaced 24 inches on center – a method that provides extra space in the wall cavity for added insulation. Additional energy enhancements included radiant barrier roof sheathing, raised heel roof trusses (also known as energy trusses), and energy-saving, high carbon trapping cellulose insulation.
Thirty-six single-family house designs were entered into the competition and evaluated by a panel of five judges. Winners were determined by a performance score based on a scientific life-cycle assessment (LCA), cost-effectiveness, and adherence to the architectural standards of a typical Florida development, among other criteria. The judges, noting that any one of the six finalists could have been selected as the Grand Prize Design winner, said that Roby’s design was “chosen for the way it squarely addressed the dual criteria of energy awareness and aesthetics without compromising affordability.”
APA and CIMA are teaming up to have Roby’s design evaluated in a comprehensive Life Cycle Analysis(LCA) study comparing the design in full wood-frame construction to construction on concrete slab with concrete block walls. The designs will also vary other construction materials to further analyze the difference in carbon impacts including cellulose versus fiberglass insulation. This independent study by the highly respected Athena Institute will compare the carbon footprints of the two homes. The results of the study will be presented in series of APA seminars this spring throughout Florida.
Look for more on the LCA study results to be posted on the CIMA website, and for information on future Carbon Challenge competitions in the coming months.
