Live from inside the TMBV Test Buildings, it’s the Thermal Mass and Buoyancy Ventilation Research team! This week the team assembled the structural and insulative envelopes of the Test Building in record time. Instead of traditional timber framing, Structural Insulated Panels (SIP) create the Test Buildings structure. After installing the SIP floors, the students assembled the remaining panels into walls, ceilings, and chimneys. This allowed for each structural plane to be craned into place. Just like a giant Leggo set! The panels were adjusted by two students in an articulating man lift and secured in place using special SIP screws. The joints where walls, floors, and ceiling met were made water and airtight with SIP sealant. In under 11 hours total, all eight walls, two ceilings, and four chimneys came together to create two sturdy, insulated shells. In the coming month, the team will weather-proof the buildings in order to begin installing the thermal mass interiors.
A little bit of Prep!
Building One: 6 Hours
Building Two: 4 hours and 45 minutes
With both buildings assembled, the Thermal Mass and Buoyancy Ventilation Research team is drinking in the rewards of their hard work. This construction method takes a lot of prefabrication and intricate planning to go so smoothly. The team loves the relations of the buildings to each other, to the Cooling Porch, and to the Morrisette Campus. They will be keeping up the momentum so make sure to stay tuned!
Live from behind one of the largest deliveries in Rural Studio history, it’s the Thermal Mass and Buoyancy Ventilation (TMBV) Research project team. For months the research team has been working closely with Insulspan, a company that manufactures custom Structural Insulated Panels (SIPs). Together they finalized the design of the SIPs which will make up the entirety of the TMBV Test Building structure and enclosure—while providing experimentally valid insulation. This week, the team received the SIPs and organized them under Rural Studio’s Fabrication Pavilion to prepare for construction. In a couple of weeks’ time the panels will be assembled atop the steel columns like a giant 3D puzzle.
SIP, SIP, Hooray!
The TMBV team originally sent the drawings seen below to Insulspan; breaking up the Test Buildings’ design into panelized pieces. The team will assemble all the pieces that make up each wall, the floor, and the ceiling. Then, Shane of Stillwater Machine LLC will crane the structure into place.
Thankfully, that same Shane with a crane was in the neighborhood when an 18-wheeler full of SIPs showed up a day earlier than expected. To get the panels off the truck Shane, his two young assistants, the TMBV team, Steve Long, and Andrew Freear got to work screwing in blocking and threading the straps. The team and helpers attached small lumber pieces (blocking) to prevent damage to the SIPs as the straps cradled the panels and lifted them off the truck.
How to Move a Building; in Pieces!
This delivery happened to take place right before a classic summer deluge. So, the SIPs were tarped and left outside the Fabrication Pavilion for the weekend. After the passing of the storm, it was time for the team to figure out how to get the panels under the Fabrication Pavilion for better protection. The Fabrication Pavilion roof is actually made of Insulspan SIPs as well. SIPs covering SIPs!
To move the panels, the team attached the lifting brackets provided by Insulspan. Then, to get the largest panels under the Fab Pav, the team used straps and the Bobcat custom, “Bob Crane.”
As the team transported the panels they also organized them. The vertical stacks group the panels by building, remember there are two, and by structure i.e. floor, ceiling, wall, or chimney. It is far easier to find the panel you need and access it when the panels are stacked this way. Also, the order of assembly was taken into consideration when sorting the panels. The floors will be assembled first on the 24′ trailer with the gooseneck attachment and then transported to the site. Next, the team will do the same thing for walls and ceilings. As far as moving the panels around under the pavilion, the students managed to do a lot by hand. With the help of an old, sturdy cart, they found in a storage barn they got everything into place and braced up.
In order to construct the floors, walls, and ceilings on the gooseneck trailer, the team had to extend the platform using TJIs donated to the Studio long ago. TJI stands for Trus Joist® TJI® Joists, they are essentially an I-beam manufactured out of engineered lumber. The TJI platform also allows the student to get underneath the panels during assembly.
With a whole lot of willpower and cart strategy, the Thermal Mass & Buoyancy Ventilation Research Team shuffled all the SIPs into place. Stay tuned for the Test Building assembly—those panels will be going up in the sky!
