[GBlist] question about turning heat down

[Anja Kollmuss <anja.kollmuss@tufts.edu>]

I teach environmental classes and I run into this question again and
again:

How much should one turn down the heat at night: It it true that it is
better not to lower the heat by more than 10 degrees (eg. to 58 from
68), because it would take more energy to heat the rooms back up (say
fom 50 to 68)?

Can someone explain this to me?
Thanks so much!
--Anja
