Load Profile Settings

You can select a load profile and view its associated parameters. With the possible exception of the Building Floor Area parameter, your administrator pre-defines the parameter values. A non-zero value in the Building Floor Area field indicates a pre-defined default value. The Building Floor Area is the only modifiable parameter in any profile.

  1. Select a profile from the Load Profile Name pulldown menu to display the profile's electric load parameters.
  2. Modify the value in the Building Floor Area field (optional). You can change a pre-defined default value or, if a pre-defined value is not available, replace the zero value with a non-zero value. The Building Floor Area represents the area of a building. If a default Building Floor Area value is not available and a non-zero value is not entered, Design Optimization uses the Floor Area Ratio to estimate the building's floor area. However, it is recommended that a value be placed in the Building Floor Area field.
    TIP: If you typed a value for the Building Floor Area, Designer saves this value when you save your design.

  3. All other Load Profile Parameters are not editable. These may be viewed by selecting the Load Profile Settings node.

    Floor Area Ratio:

    If no value exists for the Known Floor Area, the parcel area is multiplied by this ratio to calculate the floor area.

    Peak kVA Per Area:

    Maximum electric load demand per floor area.

    Average kVA Per Area:

    Average electric load demand per floor area.

    Peak PF:

    Maximum power factor per floor area.

    Average PF:

    Average power factor per floor area.

    In-Rush kVA:

    Instantaneous load required upon a motor start.

    Motor Start PF:

    Power factor required upon a motor start. This value is used to calculate flicker.

    Number of Phases:

    Number of phases for the service. Valid values are 1 or 3.

    Coincidence Curve:

    Percentage of the sum of the load for all connected service points. Expand the field to view two columns. The first is the number of service points displayed as [#]. The second column is the percentage of the total load for those service points.
