TF Transforms Dilapidated Corn Silo
into Hyper Energy Efficient and Resilient Office
Repurposing for Green


J.W. Trimmer owns more than 200 acres of farmland in the small Northeastern town of Mound City, Missouri. His farm was growing and Trimmer was in need of a new, larger office space to accommodate the growth. Located on his property was a corn silo that had fallen into a dilapidated state. “The corn silo was a well-built structure and unique, not too many of them were built this way,” Trimmer says. “However, it no longer served a useful purpose as a corn elevator. We were looking for something that it could be repurposed into. The farm had grown so we needed an office space.”

Located near Nebraska where winter temperatures can be extreme, Trimmer needed an energy efficient material and concept for his new office. “We were looking for an energy efficient material and concept,” Trimmer explained. “We compared ICF to double stud to highly insulated wall to a sip type panel…what we actually wanted to do with the radius of the corn silo is why we chose Vertical Insulated Concrete Forms by TF Forming Systems.

Steve Graham with Graham Construction was the installer on the project. This was the first building he had completed where an existing structure was repurposed and four radius walls were part of the design.

“We were impressed with the ease of being able to create the perfect radius,” said Graham. “Additionally, with this system, the homeowner should experience a lower utility bill and the structural integrity of the home, being that the walls are 8-inches and the helix added, will offer them safety for years to come.” Helix are twisted steel fibers that when added to concrete, can be replacement for rebar while still adding incredible strength to the wall.

Trimmer intends to use geothermal energy to heat the structure. He will also tie in the excess heat from the wood-fired boiler to heat the water in the radiant floor system to heat the lower level. Because of the usage of natural energy, coupled with the concrete walls and insulation on both sides of his walls, he will reduce his energy bills by well over 50 percent.

“Our house is smaller than this structure, but we are hoping with the energy efficient walls and the design aspects of the building, the bills will be comparable to a space half its size,” Trimmer says.

Resilient and Disaster Resistant
The new building, a hybrid of the existing structure and the new structure, will result in a state-of-the-art building with walls engineered to withstand 250 mph winds thanks to the slow curing process accomplished with a TF concrete wall and addition of Helix fibers to the concrete mix.

“We get intense storms and high winds. We get tornadoes that go through the area,” Trimmer says. “I was looking at a long-term structure; something that would withstand extreme weather conditions and stand for a considerable period of time.”

“This is a testament to the unique capabilities our wall systems offer,” says Kirk Brown, TF Forming Systems’ CEO. “Not only do we offer solid and affordable ways to be resilient and energy efficient, but we give building owners’ the opportunity to incorporate our wall systems into existing structures. Once again the vertical design of our system proves that we are architecturally-friendly for every application.”

The new structure will offer 4,900 square feet of space that will be used for offices, a conference room, full kitchen and guest bedrooms and living quarters. Trimmer hopes to have the building complete by April 2013.
