Tell me something

Why is it that stupid HVAC engineers put sensors OUTSIDE the building but not inside? I mean, shouldn't the temperature inside depend on what temperature it is already?! So the warmer the day is outside, the colder it is inside. Which means that it doesn't matter if we go below zero, this inverse proportional relationship holds true regardless of the icicles forming on the edge of my nose. This is how they build the buildings at BU.

I'm in intensives. It's boring. I shall blog later.
