Moving Forward

In addition to all the celebration and reviews, the team has been meeting with the Studio’s structural engineer, Joe Farruggia, to finalize the column design, and Bill Zahner, of Zahner Architectural Metals, for some advice on aluminum panel systems that are appropriate for our ceiling and roof.

We graduated!

We’re officially Auburn alumni!

See ya next time! 

Sincerely,

Official leftovers of Hale’s Kitchen.

This House is Lit

Howdy from the Patriece’s Home team! The trees are turning green here in Hale County and the 5th-year projects are emerging from Winter with pent up energy and an excitement to build!

Since their last blog post, the team completed a soil test at their site and starting identifying the home’s location on the site. They’ve also been busy developing a landscaping strategy, pushing forward with a zero eaves strategy, and designing warm, wood-clad porches.

Rural Studio students have a myriad of consultants and reviewers checking over the designs and advising the projects. Recently, the Patriece’s Home team had a visit from Pete Landon and Cameron Acheson of Landon Bone Baker Architects in Chicago, IL. The students received feedback on how they could consider detailing the column and headers of their wood-clad porch.

Next, the team met Cheryl Noel and Ravi Ricker of Wrap Architecture in Chicago, IL, for a successful code review of the home, The team then proposed the home’s lighting strategy to lighting designer Thomas Paterson of Lux Populi, from Mexico City, Mexico. He advised the team that the light desired in a home at night is not the same character of light desired during the day.

The students decided to take a trip to the 20K Model Homes at 2:00 p.m. and 8:00 p.m. to review the amount of daylight the windows provide and test what ideal nighttime lighting would be. For Patriece’s Home, the team is designing wall-mounted lighting to cast general light into a dark room and layered task lighting to illuminate highly used surfaces and spaces.  

Patriece’s Home most recently met with Rural Studio’s structural engineer, Joe Farruggia from Chicago, IL, for advice on when it is best and most economical to use laminated veneer lumber (LVLs) instead of dimensional lumber in the headers of the home. The team is also getting extremely detailed in the design of the cabinet and electrical plans, imagining how to design spaces for the hundred-year lifespan of the home.

The Patriece’s Home team is sprinting toward Pig Roast, Executive Review 2.0, and graduation, all in the next three and a half weeks! The students will begin buying materials, moving dirt on site, and constructing a full-scale mock-up of the home’s details. Stay tuned! Thanks for checking in on the project!

If You Can’t Take the Heat, Get Out of the Pavilion!

Howdy from the Moundville Pavilion team! The design has continued to evolve quickly throughout the past couple of weeks as they have been heavily focused on constructability and modifying the design of the columns. The team also got the chance recently to participate in Moundville Archaeological Park’s Knap-In, an annual stone tool makers event where visitors can learn about flint tools and how they’re made.

Columns and Ceiling

After the team clarified the design concept, new iterations of columns began to emerge that focused strongly on the overall intent of the project and its place within the site. The team looked at the columns in elevation, large-scale models, and renderings.

In conjunction with the column design, the team has also been exploring ways to give tolerance to the ceiling assembly along with the method of attaching the finished surface material to the underside of the trusses. With the decision to deconstruct the current partially built pavilion, the team has the opportunity to realign the upper or lower ridges and two of the four planes that make up the form. Aligning the upper ridge allows for smoother and faster assembly of the direct-bearing roof structure and gives shelter during the construction of the ceiling. The team also decided to add lumber to the bottom cords of the trusses to align the two lower planes. The overall goal is to allow for the most efficiency and tolerance when reconstructing the trusses.

Reviewing Executively

All of this work and response to recent guest reviewers culminated in an Executive Review, the event formerly dubbed “stress test.” The annual stress test examines each projects potential and feasibility to continue into the summer. Justin Miller (Head of the School of Architecture, Planning and Landscape Architecture), Rusty Smith (Rural Studio Associate Director), and Emily McGlohn (Rural Studio Associate Professor and leader of the 3rd-year studio) met with the team to see where the project currently is and where it is heading. 

The team presented their work at the Executive Review.

Rusty and Justin encouraged the team to consider an overlapping clip system for their ceiling and to see how we could simplify the design of the column to find a stronger balance between functionality and concept. At the end of the review, the team was challenged to build a full-scale mock-up of the final column design, complete with the roof structure, to show at the annual Pig Roast celebration at the end of the semester. 

Keep on Pushing!

In response to the feedback, the team is continuing to explore the column design, testing the suggested ceiling construction method, and mocking-up how the structure will be assembled. 

Check back soon to see where we head next as we begin to prepare for Pig Roast!

Graduate Team Completes Construction and Publishes Paper!

The Thermal Mass and Buoyancy Ventilation Research Project (TMBV) graduate students have concluded their work and time in Newbern, AL. In their wake, they leave a published, peer-reviewed paper and two research-ready buildings.

In the course of their graduate year, the TMBV project dove deep into the results of their initial small-scale experiments, culminating in a research paper published in the Journal of Physics: Conference Series as a part of the 2021 CISBAT Hybrid Scientific Conference. At the same time, the team designed and constructed two Test Buildings. The cooling and ventilation effects spurred by the optimized thermal mass will be studied throughout the next year, providing ground truth data for the system at a building scale.

The paper: A synopsis

The open-access research paper entitled, “Synchronized coupling of thermal mass and buoyancy ventilation: wood versus concrete” was published in November 2020 in the Journal of Physics Conference: Series. This was an effort involving the entire TMBV research team including Salmaan Craig, Remy Fortin, Sebastien Asselin, Kiel Moe, David Kennedy, and Andrew Freear. The paper describes small-scale experiments that test the accuracy of sizing parameters which suggest how to optimize the coupling of an internal thermal mass—which allows a building to store heat and thereby avoid major temperature fluctuations—with natural ventilation cycles, regardless of the material or the scale of the building. The results suggest the sizing parameters may be valid for early-stage design. They also show that biomaterials, such as wood, can perform as well as conventional thermal mass materials, such as concrete.

Why is this important? Typical, mechanical thermal comfort systems pump greenhouse gases into the atmosphere, raising the temperature even more. They also cannot perform in power outages during weather events caused by the ongoing climate crisis. Therefore, using regenerative materials, such as wood, to mitigate rising temperatures without reliance on the power grid suggests sustainable thermal comfort with less burden on the environment. That is an ongoing aim of the TMBV Research Project, and these initial results are an encouraging step. Before such lofty goals can be reached, the TMBV Test Buildings will provide more insight into the capabilities of the system.

The buildings: A summary

As stated above, the TMBV Test Buildings examine the coupling of thermal mass and buoyancy ventilation as a reliable thermal comfort system at the building scale. Currently, the buildings are set up for these first large-scale experiments and will later be fitted out for housing. The buildings are designed to be flexible spaces for ongoing experiments as well as dwellings for 3rd-year students. Therefore, the buildings balance valid experimental conditions, the realities of construction, and the basic needs of college students. One Test Building is powered by a plywood internal thermal mass and the other by concrete. Both buildings are designed to achieve the same performance parameters for temperature dampening and ventilation rate despite their material differences—i.e., the surface area and thickness of the material.

The buildings are the first Rural Studio buildings constructed primarily out of Structurally Insulated Panels (SIPs). Towering over the Supershed on Morrisette Campus they hover 8′ off the ground. Underneath the buildings is a gathering space nicknamed the “Cooling Porch.” During the day it is meant to collect cool air flowing out of the buildings, providing a place to enjoy the systems en masse. Air travels here through the extended chimneys, which increase ventilation speed and denote the building’s function.

With such tight buildings, dependent on accuracy, the team showed out on all the details. From three-week welding sessions to mapping out patterns of old sidewalk scrap to calculating the discharge coefficient of rooftop vent caps, this team investigated every inch. Feel free to peruse the TMBV blog to see the process, but for now here are the results.

The team: An abridgement

What a journey! These kids, ready to learn how to craft a beautiful building, were not expecting a crash course in thermodynamics, experimental design, and scientific discourse. It was an incredible opportunity to do both. Blending design, construction, and scientific rigor was an extremely unique and fulfilling educational experience. And the TMBV team sharing that experience across North America!

Rowe, the TMBV team’s certified best and most patient construction instructor, has moved to Bozeman, Montana, to join Love | Schack Architecture.

Jeff, a master of power tools and 3D modeling, is taking time to further his coding and woodworking skills.

Cory, a most relaxed, renaissance man, is enjoying his stint at the Ghost Residency with MacKay-Lyons Sweetapple Architects Limited, in Lunenburg, Nova Scotia.

Livia, the heart and volume of the operation, has settled in Austin, Texas, working with Rural Studio Alums at Thoughtbarn.

A huge thank you to the faculty and staff of Auburn University Rural Studio, the teams’ student colleagues, the project consultants (including Joe Farruggia!), the donors and teachers of Turnipseed International, and “Crane” Shane of Sweetwater Construction LLC for your time, knowledge, and support. Most obviously and ardently, thank you to the TMBV research conglomerate Salmaan Craig, Andrew Freear, Steve Long, David Kennedy, Kiel Moe, Sebastien Asselin, and Remy Fortin for the stellar work and dedication. It took a village!

This lot loves Rural Studio and all of its people. Hope to see y’all soon.

Halloween Review, Now What?

Welcome back to the 3rd-year team blog! Halloween season is a busy time for Rural Studio. Faculty, staff, and students work hard to prepare for Halloween Review presentations and the annual Pumpkin Carve.

Halloween Review

Halloween presentations went very well for the 3rd-years, Laura and Peter! Their first in-person review was a unique one, with everyone in full costume. Laura and Peter were Yzma and Kronk from the Disney movie Emperor’s New Groove.

The students have been researching post-frame construction for Rosie’s new home. They received helpful feedback from the reviews on their proposed design, including location, size, and shape of the roof. Their existing site includes several existing structures and vegetation, which limits the number of configurations for the new house.

After Halloween Reviews, the students analyzed the feedback and began to make design decisions. They narrowed down the roof structure’s footprint to 26′ x 48′. These dimensions will be the most beneficial size and scale for students next semester to continue the design development. The team used this floorplan size to then begin to study the roof’s shape and structural details.

From Pole Barn to Post Frame

Emily, Chelsea, Laura, and Peter made a trip to Greensboro, AL to study a nearby post-frame structure. Next, the team created drawings for our structural engineering consultant, Joe Farruggia, to give them feedback on its structural requirements.

Joe helped the team understand the difference between a “post-frame” roof and a “pole barn” structure. Pole barns, Joe explained, have deeper foundations and stronger connections to the ground, whereas post frames have shallower foundations but stronger connections where the posts and the trusses meet.

This past week, the students met with Van from Clockwise Components in Moundville, AL, to discuss how the post-frame steel trusses are manufactured and what the truss details might look like.

History Class Field Trips Continue

Peter and Laura continue with their weekly history classes with Dick Hudgens by touring and sketching historic homes around the West Alabama region. Their destinations have been Bluff Hall, Lions Hall, and Gaineswood in Demopolis, AL, as well as the Van De Graaff Mansion in Tuscaloosa.

They have also been working on watercolors that describe the unique landscapes of Alabama.

Woodshop Project: Library Shelves

Laura and Peter have also been busy in woodshop class with instructor, Steve Long. They are hard at work gluing, clamping, and sanding shelf carts for the Newbern Library.
