Background
Research Room Air Conditioning Tariff
Time tariff is applicable to HVAC central air conditioning wherein a/c use is based on the operating time of the room blower fan.
Energy tariff is not suited for central or VRV air conditioning as the power consumption information is not readily accessible, so time tariff is the way to go for both.
Classroom Air Conditioning Tariff
In a classroom that uses either VRV or central air conditioning, electricity tariff is not applicable, so only time tariff can be applied
