Electricity charge apportionment
calculation framework
Suppose you want to find the power consumed by the air conditioners of each
tenant from the electricity charge for each month. With electricity charge
apportionment function, used energy apportionment ratio will be provided,
calculating in detail the energy consumed by the units used by each tenant. This
information is then used to calculate the charges for the electricity consumed for
air conditioning by each tenant from the total electricity charges in the bill from
the electric power company. (See figure at right)
The detailed calculation takes into consideration such things as unused rooms
and nighttime electricity charges and shows them in a charges calculation sheet.
