My experience has been of temps in London that go down to about 32°(Freezing point), and temps in Mexico that go up to about 92°F. So my idea of "cold" is 40° below "comfortable", but Mexico's "hot" is a mere 20° above "comfortable." So, without considering any other factors, it's twice as hard to make a London house warm than it is to make a Mexican house cool.

Obviously all this varies according to preference and location, so it's an argument I'm willing to conceed - but only to people living in Death Valley.
