is_baseline_system_1c

Description: Returns true or false to whether the baseline system type is 1c (system 1 with purchased CHW and purchased HW).

Inputs:

• B-RMR: To evaluate if the hvac system is modeled as either Sys-1c in the B_RMD.
• hvac_b.id: The id of the hvac system to evaluate.
• terminal_unit_id_list: list of terminal unit IDs associated with the HVAC system to be evaluated. These are sent to this function from the is_baseline_system_1 function.
• zone_id_list: list of zone IDs associated with the HVAC system to be evaluated. TThese are sent to this function from the is_baseline_system_1 function.

Returns:

• is_baseline_system_1c: Returns true or false to whether the baseline system type is 1c (system 1 with purchased CHW and purchased HW).

Function Call:

1. is_hvac_sys_cooling_type_none()
2. are_all_terminal_heat_sources_hot_water()
3. are_all_terminal_cool_sources_chilled_water()
4. do_all_terminals_have_one_fan()
5. are_all_terminal_types_CAV_With_None_Equal_to_Null ()()
6. does_each_zone_have_only_one_terminal()
7. all_terminal_chw_loops_purchased_cooling()
8. are_all_terminal_heating_loops_purchased_heating()

Logic:

• Create an object associated with the hvac system: hvac_b = hvac_b.id
• Set is_baseline_system_1c = FALSE: is_baseline_system_1c == FALSE
• Check that there is no preheat system, if there is none then carry on: if len(hvac_b.preheat_system) == Null or hvac_b.preheat_system[0].heating_system_type == "NONE" :
  • Check that there is no heating system, if there is none then carry on: if len(hvac_b.heating_system) == Null or hvac_b.heating_system[0].heating_system_type == "NONE":
    • Check that there is no fan system, if there is none then carry on: if len(hvac_b.fan_system) == Null:
      • Check that there is no cooling system if there is none then carry on: is_hvac_sys_cooling_type_none(B_RMR, hvac_b.id) == TRUE
        • Check if the zones only have one terminal unit: if does_each_zone_have_only_one_terminal(B_RMR,zone_id_list) == TRUE:
          • Check that the data elements associated with the terminal unit align with system 1c, if yes then carry on: if are_all_terminal_heat_sources_hot_water(B_RMR,terminal_unit_id_list) == TRUE AND are_all_terminal_cool_sources_chilled_water(B_RMR,terminal_unit_id_list) == TRUE And do_all_terminals_have_one_fan( B_RMR,terminal_unit_id_list) == TRUE AND are_all_terminal_types_CAV_With_None_Equal_to_Null (B_RMR,terminal_unit_id_list) == TRUE:
            • Check if all terminal HW loops are purchased heating: if are_all_terminal_heating_loops_purchased_heating(B_RMR,terminal_unit_id_list) == TRUE:
              • Check if all termina CHW loop are purchased cooling: if are_all_terminal_chw_loops_purchased_cooling(B_RMR,terminal_unit_id_list) == TRUE: is_baseline_system_1c == TRUE

Returns is_baseline_system_1c
