Hi guys! I want to conduct an economic analysis with the aid of EnergyPlus. I need to use different rates for each year from 2015 to 2019. Is it possible to define these yearly different rates or I have to run EnergyPlus for each year separately? Thanks in advance.
If you are simulating multiple years with different weather data each year, I don't think you can have different tariffs apply to different years using the Economic:Tariff objects in EnergyPlus. Instead you would have to simulate each year separately with different tariff associated with each year.
If your weather is going to be the same for each year, you could just define multiple tariffs in a single EnergyPlus file and simulate just the one year. You would then get all the results for the different tariffs in the Economics Results Summary Report report.
Thanks for your help. I used your method to calculate annual energy costs. Now I want to analyze the life cycle cost of my building for 20 years. I know that I can change Electricity and NG cost per unit values for all years by using the object LifeCycleCost:UsePriceEscalation. However, when I did this, EnergyPlus calculated the energy cost for all years the same in the life-cycle cost report.
I defined the Resource field in the object LifeCycleCost:UsePriceEscalation as ElectricityPurchased and NaturalGas and their relative Output Meter Name in the object UtilityCost:Tariff are ElectricityPurchased:Facility and Gas:Facility respectively, but nothing changed. Can you please tell me why annual energy costs don't change? Thank you very much.
It would probably be best to make this a new question. If you do, please post the LifeCycleCost objects from your IDF file so that we can see what you are doing.
