If that isn't the case, wouldn't there be an eqn where I could take a room temp curve and come up with predicted curves as a function of temp?

Probably could get predictions, but would possibly come up with something like this:

These changes appears to adequately descibe behavior down to Temps a couple of Degrees above 0c.,but do not account for behaviour bellow.
