A few input fields exist within the Audit Template that may not be compatible with importing and/or  exporting BuildingSync XML files, as outlined below.  

Chiller Compressor Type

In the Cooling Plants section of the HVAC data entry screen, the "Chiller Compressor Type" field is only displayed when the selected cooling plant type is "Electric Chiller".  In BuildingSync XML, the corresponding XML element may still be used:

<auc:CoolingPlant>

  <auc:CoolingPlantType>

    <auc:Chiller>

       <auc:ChillerCompressorType>Rp::CoolingPlant#rp_compressor_type</auc:ChillerCompressorType>

    </auc:Chiller>

  </auc:CoolingPlantType>

</auc:CoolingPlant>

Hence, at import, the value of the Rp::CoolingPlant#rp_compressor_type attribute is lost unless the selected cooling plant type is "Electric Chiller".  The Chiller Compressor Type attributes are:  Scroll, Reciprocating, Centrifugal, and Screw.

Foundation R Value

In the Foundation Types section of the Construction data entry screen, the "Foundation R Value" field is always displayed, regardless of the selected foundation type.

In BuildingSync XML, the XML elements that correspond to the "Other (Please Specify)" and "Unknown" foundation types have no child elements:

<auc:FoundationSystem>

  <auc:FoundationSystemType>

    <auc:Other/>

  </auc:FoundationSystemType>

</auc:FoundationSystem>

or

<auc:FoundationSystem>

  <auc:FoundationSystemType>

    <auc:Unknown/>

  </auc:FoundationSystemType>

</auc:FoundationSystem>

Hence, at export, the value of the Rp::Foundation#r_value attribute is not present in the BuildingSync XML document.

Heating Plant Equipment Details

In the Heating Plants section of the HVAC data entry screen, the "Efficiency Units", "Number of Pieces of Equipment", "Output Capacity" and "Rated Efficiency" fields are not displayed when the selected heating plant type is "District Hot Water" or "Utility District Steam".

In BuildingSync XML, the corresponding XML elements may still be used:

<auc:HeatingPlant>

  <auc:HeatingPlantType>

    <auc:DistrictHeating>

<auc:OutputCapacity>Rp::HeatingPlant#output_capacity</auc:OutputCapacity>

<auc:AnnualHeatingEfficiencyValue>Rp::HeatingPlant#rated_efficiency</auc:AnnualHeatingEfficiencyValue>

<auc:AnnualHeatingEfficiencyUnits>Rp::HeatingPlant#rp_efficiency_unit</auc:AnnualHeatingEfficiencyUnits>

<auc:Quantity>Rp::HeatingPlant#pieces_of_equipment</auc:Quantity>

    </auc:DistrictHeating>

  </auc:HeatingPlantType>

</auc:HeatingPlant>

Hence, at import, the values of the Rp::HeatingPlant#output_capacity, Rp::HeatingPlant#pieces_of_equipment, Rp::HeatingPlant#rated_efficiency and Rp::HeatingPlant#rp_efficiency_unit attributes are lost.
