Rate Schedule Setup
Before you set up an efficiency report, set up a Rate schedule that defines the efficiency
calculation. Enter the efficiency calculation in Line Item 1 in the rate schedule. Set up the
line item script to perform the efficiency calculation and set the Quantity variable to the
result. A sample line item script for calculating boiler efficiency (in British units) is
provided below:
Dim avg_gas, avg_steam
avg_steam=Average(ValueType.SteamFlow)
avg_gas=Average(ValueType.GasFlow)
if avg_gas=0
Quantity=0
else
Quantity=avg_steam*99.4 / avg_gas
end if
