By Philip Schmidt, Networx Don’t worry: You won’t have to endure
a lecture on thermodynamics to understand how to cool your home
more efficiently. In fact, there are only two basic scientific
principles that you need to know, and you’re sure to be familiar
with at least one of them. The first is: heat follows cold. The
second is: hot air rises. Thinking about these two rules of
nature will help you see how air moves in and around your house
and how that relates to cooling (and heating) efficiency.
