Description: Get the list of HeatingVentilationAirAconditioningSystem in which Appendix G Table G3.1 #10 c is applicable (i.e. space heating is modeled in the P_RMI but not the U_RMI). Table G3.1 #10 c states that "where no heating system exists or no heating system has been submitted with design documents, the system type shall be the same system as modeled in the baseline building design and shall comply with but not exceed the requirements of Section 6."
Inputs:
- U-RMD: The U-RMD to determine if an HVAC system has been designed or is existing with heating.
- P-RMD: To determine if the same HVAC system has been modeled with heating in the P-RMD.
Returns:
- proposed_hvac_modeled_with_virtual_heating_list_p: A list that saves all the HVAC systems in which Appendix G Table G3.1 #10 c are applicable (i.e. modeled with virtual heating in the proposed).
Function Call:
- match_data_element()
- match_data_element_exist()
- For each hvac_p in the the P_RMI:
for hvac_p in P_RMI...HeatingVentilationAirConditioningSystem:- Reset has_virtual_heating_p boolean variable:
has_virtual_heating_p = FALSE
Below compares the heating systems associated with the hvac system across the P_RMI and U_RMI only if heating was modeled in the proposed. If heating was modeled in the proposed and NOT in the U_RMI (the heating system type is None [or heating_system = Null] in the U_RMI) then this means virtual heating was modeled in the proposed. We are checking the preheat coils because baseline systems 5 through 8 have preheat coils. - Check if there are any heating_system associated with hvac_p, if not skip to preheat check:
if hvac_p.heating_system != Null:- For each heating_system_p in hvac_p:
for heating_system_p in hvac_p.heating_system:- Check if "None" is NOT the heating_system_type for heating_system_p, if its not "None" (means heating was modeled) then get the analogous heating system in the U_RMI (if it exists) and check if the heating_system_type is "None" in the U_RMI:
if heating_system_p.heating_system_type != "None":- Check if analogous heating system exists in the U_RMI:
if match_data_element_exist(U_RMI,HeatingSystem,heating_system_p.id) == TRUE:- Get analogous heating system in U_RMI:
heating_system_u = match_data_element(U_RMI,HeatingSystem,heating_system_p.id) - Check if the analogous system in the U_RMI has a heating system type equal to "None", if it does then set the has_virtual_heating_p boolean variable to TRUE:
if heating_system_u.heating_system_type == "None": has_virtual_heating_p = TRUE
- Get analogous heating system in U_RMI:
- Else, if the analogous heating system does not exist in the U_RMI, then set has_virtual_heating_p boolean variable to TRUE:

- Check if analogous heating system exists in the U_RMI:
- Check if "None" is NOT the heating_system_type for heating_system_p, if its not "None" (means heating was modeled) then get the analogous heating system in the U_RMI (if it exists) and check if the heating_system_type is "None" in the U_RMI:

if hvac_p.preheat_system != Null:- For each preheat_system_p in hvac_p:
for preheat_system_p in hvac_p.preheat_system:- Check if "None" is NOT the preheat_system_type for preheat_system_p, if its not "None" (means preheat was modeled) then get the analogous preheat system in the U_RMI (if it exists) and check if the preheat_system_type is "None" in the U_RMI:
if preheat_system_p.preheat_system_type != "None":- Check if analogous preheat system exists in the U_RMI:
if match_data_element_exist(U_RMI,HeatingSystem,preheat_system_p.id) == TRUE:- Get analogous preheat system in U_RMI:

if preheat_system_u.preheat_system_type == "None": has_virtual_heating_p = TRUE
- Get analogous preheat system in U_RMI:
- Else, if the analogous preheat system does not exist in the U_RMI, then set has_virtual_heating_p boolean variable to TRUE:

- Check if analogous preheat system exists in the U_RMI:
- Check if "None" is NOT the preheat_system_type for preheat_system_p, if its not "None" (means preheat was modeled) then get the analogous preheat system in the U_RMI (if it exists) and check if the preheat_system_type is "None" in the U_RMI:

- Check if there are any preheat_system associated with hvac_p, if not skip indented code:
- Check if heating was modeled in the proposed via has_virtual_heating_p boolean variable (and not in the U_RMI) add hvac system to list:
