Greetings, Having selected the E+ measure: "Xcel EDA Tariff" and selecting from available gas and electric tariffs as well as imputing costs associated with a measure I was looking to see some reporting on measures savings in dollars. Is this currently possible within either OS or PAT? Thank you, Matt

I think the standard PAT results described here should be what you are looking for. If you want to know what the savings is from a specific measure then you need to run a design alternative with only that measure applied. This avoids any interactions with other measures.

We do have an analysis period cash flow reporting measure that reports cash flow over the analysis period. It just graphs data that comes out of EnergyPlus

Hi David,
Where does the Analysis Period Cash Flow get the utility costs?

Ultimately EnergyPlus is doing all of the life cycle cost calculations. All of the utility tariffs and component cost line items are input to EnergyPlus and EnergyPlus calculates all of the cash flows. Does that answer your question?
