I was wondering if anyone has experience adding lifecycle costs to EnergyPlus for water consumption.

I was able to add water costs as a fuel using UtilityCost:Tariff object, but in that scenario it shows up under "Energy" instead of "Water" on the "Operating Cash Flow by Category (Witihout Escalation) " table which isn't ideal. Has anyone taken a different approach where they were able to populate the "Water" column?

Here is the table in question.

Here is the EnergyTable which feeds into the "Energy" column above. Notice that it does include water costs. image description

And here is my Tariff object.

  Water Tariff,                           !- Name
  Water:Facility,                         !- Output Meter Name
  UserDefined,                            !- Conversion Factor Choice
  1,                                      !- Energy Conversion Factor
  ,                                       !- Demand Conversion Factor
  ,                                       !- Time of Use Period Schedule Name
  ,                                       !- Season Schedule Name
  ,                                       !- Month Schedule Name
  ,                                       !- Demand Window Length
  0.0;                                    !- Monthly Charge or Variable Name

  WaterTariffEnergyCharge,                !- Name
  Water Tariff,                           !- Tariff Name
  totalEnergy,                            !- Source Variable
  Annual,                                 !- Season
  EnergyCharges,                          !- Category Variable Name
  10.0;                                   !- Cost per Unit Value or Variable Name

It may be bug, but I thought I'd see if anyone else had been successful with water lifecycle costs before I filed anything.

What version of EnergyPlus are you using? I tried running 5ZoneEconomicsTariffAndLifeCycleCosts.idf which includes water costs with EnergyPlus 8.6 and it seemed to work and populate the Operating Cash Flow by Category (Without Escalation) table.

@David Goldwasser it looks like this was an issue in EnergyPlus v8.3, which @JasonGlazer fixed for v8.6 according to this Github thread.
