Elevators – Rule 16-3

Schema Version: 0.0.36
Mandatory Rule: True
Rule ID: 16-3
Rule Description: The elevator cab ventilation fan shall be modeled with the same schedule as the elevator motor.
Rule Assertion: P-RMD = Expected Value
Appendix G Section: G3.1
Appendix G Section Reference: Table G3.1-16 Proposed Building Performance
Data Lookup: None
Evaluation Context: Each elevator

Applicability Checks:

  1. The proposed and baseline buildings have an elevator.

Function Call:
compare_schedules

Applicability Check 1:

  • Rule is applicable if the proposed and baseline RMD contain at least 1 elevator: if find_all("$.buildings[*].elevators[*]", rmd_b) and find_all("$.buildings[*].elevators[*]", rmd_p):

Rule Logic:

  • Determine if the project schedule uses a leap year: is_leap_year = RPD.calendar.is_leap_year

  • If it is a leap year, set the schedule comparison mask to 8784 hours, else set it to 8760 hours: mask_schedule = [1] * 8784 if is_leap_year else [1] * 8760

  • For each elevator in the proposed RMD: for elevator in P_RMD...elevators

    • Get the modeled schedule for the elevator motor use in the proposed: motor_use_schedule_p = elevator_p.cab_motor_multiplier_schedule
    • Get the modeled schedule for the elevator cab ventilation use in the proposed: cab_ventilation_schedule_p = elevator_p.cab_ventilation_fan_multiplier_schedule
    • Compare the schedules: comparison_data = compare_schedules(cab_ventilation_schedule_p, motor_use_schedule_p, mask_schedule, is_leap_year):

    Rule Assertion:

    • Case 1: If the schedules match for all hours: if comparison_data['total_hours_matched'] == len(cab_ventilation_schedule_p) == len(motor_use_schedule_p): PASS
    • Case 2: Else: FAIL

Notes/Questions: None
