Always turn down the heat/AC when I am out for the day.

According to the DOE (Department of Energy), the heating and cooling load of your building could decrease by 2-3 percent, if all its occupants adjusted their thermostats by even just a few degrees (down in winter and up in summer). If you live in a JTS Residence Hall, be sure to tell your RD if your room is overheated in the winter or overcooled in the summer.
