earthtubes

Let’s do some tests!

Hello from Reggie’s Home! In an effort to create a design that fully responds to the conditions of the site we decided to conduct some soil test to determine where the best places to grow Reggie’s desired fruits and vegetables would be. In order to conduct the test we divided our site into three parts: the front of the site, the part where the old family home stood, and the back of the site where Reggie has been cutting down privet. We collected soil from these areas and sent them to Auburn University’s soil testing laboratory to be tested.

We have also been researching the plants Reggie wishes to grow to figure out what type of sun and soil they need, as well as what seasons the crops would be harvested. This research and the soil test results led us to determine the best place for Reggie to have a garden would be the north side of the site. With this information we were able to get a more accurate master plan of the site.

In addition to researching plants available to grow on our site we also continued our research with Earth Tubes, a form of passive heating and cooling. Earth Tubes are essentially buried ventilation ducts that heat or cool the air moving through them because of the constant temperature of the soil. A big question that comes with Earth Tubes is whether or not it will work in our climate due to the humidity. Lucky for us, the Rural Studio Farm Storehouse uses earth tubes in an effort to keep produce at a constant temperature. We have been monitoring the temperature and humidity outside the storehouse and outtake of the Earth Tube to see how effective it is. After a month of recording temperature we discovered a change of temperature from 6-10 degrees. With this information we contacted Adam Pyrek, an Environmental Controls professor from the University of Texas at Austin, to consult whether Earth tubes would be feasible as part of our home design. He encouraged us to continue the research on the temperature and humidity of the storehouse and to keep in mind that Earth Tubes are ideal for keeping a small space at a constant temperature.

With all this information we will be pushing the design of the home as well as the site as a whole forward!

Until next week,
