Hi,

I model a building in OpenStudio and try to compare the hourly chiller evaporator cooling rates between actual and modeled chillers. It seems like the modeled outputs have jumping values during the first hours as shown in the chart. I use the OS:Chiller:Electric:EIR class to model the chillers. I am not sure whether this is common or it's an error from my inputs. Could anyone please recommend some methods to deal with these first-hour spikes?

Thank you.
