Conclusions 1

As MEEB pages 127-8 says, when a sufficient temperature differential builds up, there is a stack effect in the space. However, the temperature differential in the time period we were measuring in seldom was large enough to drive the effect. Surprisingly, though, the reported exterior temperature does not seem to correlate at all with the stack effect. It may be:

  1. That the temperature at Eugene Airport (Mahlon-Sweet Airport, to be technical) is not very close to the temperature on the University of Oregon's Eugene campus.
  2. Characteristics of the space may make the measured outside temperature insignificant.
  3. Another, as yet undetermined, factor has come into play.
