From costume contests to coding classes, the Thermal Mass and Buoyancy Ventilation Research Project takes on a new form everyday.
In the past weeks, the team has been designing a Pod which is a small dwelling or dorm that 3rd-years use for sleep and storage. The Pod will be used to test the Optimal Tuning Theory. The team presented the Optimal Tuning Theory and their current pod design at the annual Rural Studio Halloween Review. Unfortunately, all of you lovely readers were not able to make the review, so this post will be dedicated to explaining the Optimal Tuning Theory and showing off the teams Halloween Review Costumes.
What is the Optimal Tuning Theory?
First, let’s get a couple of definitions out of the way, what are Thermal Mass and Buoyancy Ventilation? Thermal Mass is a property of the mass of a building which enables it to store and release heat. A typical example would be an adobe home or pueblo where the thick, earthen walls absorb the hot, desert sun during the day keeping the interior space cool. Later during the cold, desert night the thick, earthen walls release that heat into the interior thus warming the space. Buoyancy Ventilation, often refereed to as the “stack” or “chimney” effect, utilizes the natural ventilation cycle of hot air rising and cool air falling to supply air to a space without mechanical systems.
BUILD THE COSTUME BE THE COSTUME MAKE A MESS
The Optimal Tuning Theory theorizes that a space can be comfortably and passively ventilated, heated, and cooled by coupling an internal Thermal Mass with Buoyancy Ventilation. If these systems are synchronized or “optimally tuned” it would allow architects and builders to use the ancient practice of Thermal Mass building in a more predictive manner. The typical issue with Thermal Mass buildings is that the Thermal Mass is never able to release all the heat it absorbed in the day, therefore the cycle does not start over the next day and the passive system does not work efficiently. By keeping the Thermal Mass on the interior, shaded from the sun and insulated, and using Buoyancy Ventilation to draw out access heat or supply heat from the air, the system is able to reset for the next day. The Optimal Tuning Theory is the crux of the Thermal Mass and Buoyancy Ventilation Research Project.
The Thermal Mass and Buoyancy Ventilation Research Project Team will build a Pod as a scientific instrument to test the Optimal Tuning Theory. A Pod is an appropriate, human scale that they can test the temperature and air flows of easily and can be inhabited by 3rd-years later on.
Now for the real magic, Rural Studio’s own Transformers! Each TMBVRP team member transformed into a classic Rural Studio vehicle. From left to right starred: Livia Barrett as Andrew Freear’s Honda Fit including his front license plate that reads “British Nut;” Rowe Price as the crisp, new Student Truck; Cory Subasic as Hale County Classic Tractor fit with hand wheels; and Jeff Jeong as our beloved Johnny Parker’s beloved BobCat. The team came second in the local costume contest, but Jeff won Best Pumpkin! Thanks for TUNING in, we hope to see you at Soup Roast!
