Monthly reports broadly summarize building performance. The information they contain varies depending upon the EnergyPlus properties being reported in each predefined monthly report. The table below lists each monthly report, the predefined EnergyPlus properties it reports and their value types. Descriptions of the value types are at the bottom of this section, below the table.

Value Types

• SumOrAverage — Sum adds the values for each timestep and reports the sum of the value monthly. Average lists the average value for the month.
• Maximum — Reports the maximum value and the time it occurred. When Maximum is used with Sum, the value is divided by the length of the timestep in seconds.
• Minimum — Reports the minimum value and the time it occurred. When Minimum is used with Sum, the value is divided by the length of the timestep in seconds.
• HoursNonZero — Adds the elapsed time during the month that the associated property value is not equal to zero. This is an appropriate way to determine the number of hours that a fan operates.
• HoursZero — Adds the elapsed time during the month that the associated property value is equal to zero. This is an appropriate way to determine the number of hours that a fan does not operate.
• HoursPositive — Adds the elapsed time during the month that the associated property value has a positive value. Hours with a zero value are not included.
• HoursNonPositive — Adds the elapsed time during the month that the associated property value has non-positive value. Hours with a negative value and hours with a zero value are all included.
• HoursNegative — Adds the elapsed time during the month that the associated property value has a negative value. Hours with a zero value are not included.
• HoursNonNegative — Adds up the elapsed time during the month that the associated property value has a non-negative value. Hours with a positive value and hours with a zero value are all included.
• ValueWhenMaximumOrMinimum — Evaluates the previous EnergyPlus property in the report that sets a maximum or minimum and displays the value of the current variable at that same timestep. The order of the EnergyPlus properties is important when using ValueWhenMaximumOrMinimum. For instance, ValueWhenMaximumOrMinimum can be used when an outdoor temperature is reported for the time of the maximum cooling load.
• SumOrAverageDuringHoursShown — Provides the sum or average of the EnergyPlus property during the hours the previous variable displayed with any of the value types starting with “Hours”. For Sum, it adds the values for each timestep and reports the sum monthly during the hours reported on the previous variable. For Average, the value shown will be the average for the month during the hours reported on the previous EnergyPlus property. The order of the EnergyPlus properties is important when using SumOrAverageDuringHoursShown.
• MaximumDuringHoursShown — Reports the maximum value and the time the maximum value occurred but only during the hours reported with the previous value types starting with “Hours”. When used with Sum, the value is divided by the length of the timestep in seconds. For instance, the maximum for a variable in Joules is reported in Watts. The order of the EnergyPlus properties is important when using MaximumDuringHoursShown.
• MinimumDuringHoursShown — Reports the minimum value and the time the minimum value occurred but only during the hours reported with the previous value types starting with “Hours”. When used with Sum, the value is divided by the length of the timestep in seconds. For example, the minimum for a variable in Joules is reported in Watts. The order of the EnergyPlus properties is important when using MinimumDuringHoursShown.
