    • Introduction

    The userdata_electric_equipment.csv contains compliance data for electric equipment compliance calculations that includes receptacles and process loads including motors, elevators and refrigeration equipment loads.

    It consists of the following fields:

    For example, consider 2 elevators for 3 stories in a building. One of the line items in the .csv would be put in as follows:

    name fraction_of_controlled_receptacles receptacle_power_savings motor_horsepower motor_efficiency motor_is_exempt elevator_weight_of_car elevator_rated_load
    2 Elevator Lift Motors 1999 0.72 false 1000 900
    elevator_counter_weight_of_car elevator_speed_of_car elevator_number_of_stories elevator_number_of_lifts elevator_area_ft2 elevator_ventilation_cfm refrigeration_equipment_class
    1200 200 3 2 25 1000
    refrigeration_equipment_volume refrigeration_equipment_total_display_area
    0 0

    Line items for receptacles and refrigeration equipments can also be added in the same .csv in a similar manner.

    Data Fields Details

    Here is a detailed explanation of what each data field requires.

    name

    Name of the electric equipment object in the model.

    fraction_of_controlled_receptacles

    This field is used to input the percentage of all controlled receptacles as a fraction. It requires a float value between 0 and 1. This value will be used to calculate the receptacle power credits according to the methodology mentioned in Table G3.1 Section 12.

    receptacle_power_savings

    This field is used to input the receptacle power savings directly instead of entering the fraction of controlled receptacles. One thing to remember is if both fraction_of_controlled_receptacles and receptacle_power_savings are defined in the .csv, the PRM measure will use fraction_of_controlled_receptacles.

    motor_horsepower

    This field is used to input the horsepower of the motor.

    motor_efficiency

    This field is used to input the efficiency of the motor as a percentage. It must be set up with a value from Table G3.9.1.

    motor_is_exempt

    Set this field to true if the motor is exempt. If it doesn’t apply, set it as false or leave empty.

    elevator_weight_of_car

    This field is used to input the weight of the elevator car in pounds.

    elevator_rated_load

    This field is used to input the proposed design elevator load at which to operate, in pounds.

    elevator_counter_weight_of_car

    This field is used to input the counterweight of the elevator car from Table G3.9.2, in pounds.

    elevator_speed_of_car

    This field is used to input the speed of the proposed elevator, in feet per minute.

    elevator_number_of_stories

    This field is used to input the number of stories (including basement) that is covered by the elevator.

    elevator_number_of_lifts

    This field is used to input the number of elevators.

    elevator_area_ft2

    This field is used to input the area of the elevator, in square feet.

    elevator_ventilation_cfm

    This field is used to input elevator ventilation fan specification, in Watt per cfm.

    refrigeration_equipment_class

    This field is used to input the class of the refreigeration equipment. it consists of a combination of an equipment family code, and operating mode code and a rating temperature as shown in Table G3.10.2.

    refrigeration_equipment_volume

    Ths field is used to input the volume of the chiller or frozen compartment, in cubic feet. Refer to Table G3.10.1.

    refrigeration_equipment_total_display_area

    This field is used to input the total display area of the refrigeration equipment.
