Spain has just passed a law to regulate temperature in public places like government offices, bars and shops. It shouldn't be higher than 21ºC in the winter, it shouldn't be less than 25ºC in the summer. Of course, what it's being regulated is the heating or AC devices! :-)

Hopefully this law will prevent us to freeze in theatres in the summer. And of course, it will reduce energy comsumption. There are more measures like forcing locals to have automatic-closing doors.
