Clemson University’s School of Architecture is developing an innovative new construction method that is gaining worldwide attention for its potential market impact in rapid, low-tech sustainable housing.
Using the sim[PLY] Framing System, “With a click of the button, someone could order a custom-cut, flat-packed home online and construct it by hand with the help of their friends and neighbors in a matter of days,” said Kate Schwennsen, professor and director of the School of Architecture.
One of the sim[PLY] Framing System’s innovative advantages is its revolutionary interlocking tab-and-slot connection system (patent pending). Assembly is intuitive and easy; so buildings come together much like a 3D puzzle, using no nails, just steel zip ties and some screws. This means buildings can be disassembled just as easily, without causing structural damage.
“sim[PLY] is faster, safer, easier and more energy-efficient than traditional construction with power tools,” Schwennsen said.
sim[PLY] offers a rapid, low-tech construction solution with a profound reduction in a building’s total carbon footprint. Here’s how:
- sim[PLY] uses locally sourced plywood and computer numeric control (CNC) fabrication.
- Construction plans are digital and can be emailed anywhere there is a CNC controller.
- Components can be pre-cut using off-the-shelf materials, pre-measured and flat-packed, requiring less transport space and smaller vehicles versus other forms of prefabricated structures.
- Cut pieces lock into place on site with no power-operated tools or heavy equipment required.
sim[PLY]’s evolving impact:
- A national Department of Defense (DOD) building contractor has looked at sim[PLY] for Rapidly Deployable Housing applications, such as for use in temporary military housing. sim[PLY] is being considered as a potentially cost-saving opportunity to build better structures faster, safer and using less energy on the jobsite.
- sim[PLY] ’s built-in ease of construction makes it an ideal framing model for various types of do-it-yourself housing. Think: tiny homes. To explore this popular housing trend, Clemson’s architectural students have designed an energy efficient sim[PLY] tiny home prototype that could be structurally framed in just one day’s time.
- Timber is one of South Carolina’s most important cash crops, with an economic impact of $20 billion, according to the Forestry Association of South Carolina. sim[PLY]’s use of plywood would create both a positive economic and environmental impact here at home. Beyond causing a greater demand for timber, wide acceptance of the sim[PLY] process would mean a more diverse and robust use of forest resources; plywood manufacturing, unlike that of lumber, makes use of older, more mature trees.
- Architectural communities in Italy, Austria and Germany – countries considered to be worldwide leaders in wood construction and sustainable building – have expressed interest in sim[PLY]. Overseas and in the U.S., sim[PLY]’s sustainable performance benefits are compelling.
An example of a sim[PLY] structure in use is the CropStop community kitchen on Lois Avenue in Greenville. The building makes it possible for crop owners to better process their harvests to meet local demand for fresh farm-to-table foods. A new universal CropStop prototype was designed in the fall and could impact global agrarian economies where there is interest in this concept for sustaining local growers and evolving farm communities.
sim[PLY] was first developed by Clemson architectural faculty and students as part of their entry in the 2015 Department of Energy Solar Decathlon competition. While their end result was a solar-powered, energy-efficient home, it was just the beginning for the innovative framing system that is proving it has a marketable life of its own.
“sim[PLY] is an ongoing, evolving project,” Schwennsen said. “New teams of students are being challenged to optimize the design and create newer, smarter versions to meet the needs of a variety of commercial, government and end-user market applications.”
The School of Architecture and its faculty continue to be leaders in integrating critical and creative research into its nationally ranked accredited graduate program.
The sim[PLY] team includes faculty inventors Dan Harding, Dustin Albright, Dave Pastre, Ulrike Heine, Vincent Blouin and Ufuk Ursoy; and contributing student inventors Anthony Wohlers, Michael Stoner, Eric Balogh, Tyler Silvers, Clair Dias, Alison Martin, Jon Pennington, Jeff Hammer, Will Hinkley, Justin Hamrick, Alexandra Latham, Neely Leslie, Daniel Taylor, David Herrero, Rebecca Mercer, Russell Buchanan, Amelia Brackmann, Paul Mosher, Allyson Beck and Alex Libengood.
