With smart thermostats, we get statistics comparing our usage with other homes.

We did the same thing 2 years ago with a 4 zone Trane system. There is a master control and then each zone has its own t-stat board. Guests can control temps that they like for sleeping at their end of the house. In the evening in great room, we have that zone cooling us. During sleep time, only our master bedroom is running AC at 71and the rest of the house is 79. It was pricey but we love it. We figured about 10 years to recoup the efficiency savings as we are really noticing a nice reduction in our HVAC bills.
