Service_Water_Heating - Rule 11-11

Schema Version: 0.0.37

Mandatory Rule: TRUE

Rule ID: 11-11

Rule Description: For buildings that will have no service water-heating loads, no service water-heating shall be modeled in baseline building model

Rule Assertion: Options are PASS/FAIL/NOT_APPLICABLE

Appendix G Section Reference: Table G3.1 #11, baseline column, c

Evaluation Context: B-RMD each building segment Data Lookup:

Function Call:

  • get_component_by_id
  • get_SWH_components_associated_with_each_swh_bat
  • get_SWH_types_and_SWH_use
  • get_SWH_uses_associated_with_each_building_segment

Applicability Checks:

  • look at each building segment in the proposed model: for building_segment in P_RMD.building.building_segments:

    • create a boolean has_swh_loads and set it to false: has_swh_loads = false

    • get the service water heating uses in the proposed building segment service_water_heating_use_ids = get_swh_uses_associated_with_each_building_segment(P_RMD, building_segment.id)

    • look at each service water heating use id: for swh_use_id in service_water_heating_use_ids:

      • get the swh_use using get_component_by_ID: swh_use = get_component_by_ID(P_RMD, swh_use_id)
      • check to see if the swh use is greater than 0 (ie there is any amount of hot water used): if swh_use.use > 0:
        • set has_swh_loads to true: has_swh_loads = true

    • if we arrive here with has_swh_loads still equal to false, CONTINUE TO RULE LOGIC: if has_swh_loads == FALSE: CONTINUE TO RULE LOGIC

    • otherwise, the rule is not applicable: else: NOT_APPLICABLE

    Rule Logic:

    • look at the same building segment in the baseline model, and make sure that there are no SWH loads in the baseline model
    • create a boolean has_swh_loads and set it to false: has_swh_loads_b = false
    • get the service water heating uses in the building segment service_water_heating_use_ids = get_swh_uses_associated_with_each_building_segment(B_RMD, building_segment.id)
    • look at each service water heating use id: for swh_use_id_b in service_water_heating_use_ids:
      • get the swh_use_b using get_component_by_ID: swh_use_b = get_component_by_ID(B_RMD, swh_use_id_b)
      • check to see if the swh use is greater than 0 (ie there is any amount of hot water used): if swh_use_b.use > 0:
        • set has_swh_loads to true: has_swh_loads_b = true

Rule Assertion:

  • Case1: the baseline doesn't have any SWH use loads: PASS: if !has_swh_loads_b: PASS

  • Case2: all other cases is a fail: else: FAIL
