Abstract

In creating this case study, our purpose was to reduce interior temperature fluctuations of a room by the addition of a thermally massive wall against a south-facing window. The experiment was conducted in a room with 7’ x 12’ dimensions at 12th and Ferry streets in Eugene. Throughout the process, the room remained sealed off from outside interference and the local weather maintained a rather consistent sunny 30-45 degree Fahrenheit range. In preparation for study, three HOBO data collectors were set up throughout the room and one outside. After a number of days, we constructed a wall of plastic water gallons and continued to measure temperature fluctuations. The thermal wall left us with inconclusive evidence; from the charts the HOBO recorded inconsistent temperature fluctuations not allowing us enough ample information to form a complete conclusion.
