Elec rates in Philippines sre twice that of N America. People leave A/C on and go out all day. Elec costsa can be 40% of daily rate. I installed a meter in unit,include 8 kwh per day in daily rate and charge for any over the cap. Posted in my house rules, I explain on check in and so far no real complaints. Some are nervous, but it is works out, no waste of resources. My elec bill is less than half before i installed the meter.
