Hi,

I am trying to get the zones load break down using "Zone Report" measure, but every time I use the measure I get the the below error. I tried different versions of the measure, also tried to download the measure and add it to "my measures" and use it from there. I am not sure if this is because the measure is not compatible with the OpenStudio version 2.6 that I am using, or if there is something should be done before using this measure?

Thank you,

@Saif that looks like an error in the measure specific to CoilCoolingWaterToAirHeatPumpEquationFit objects, we called invalid methods for this object type. I'll file an issue for this. It was failing on the last line in code below.

when OpenStudio::Model::CoilCoolingWaterToAirHeatPumpEquationFit.iddObjectType
    coil = e.to_CoilCoolingWaterToAirHeatPumpEquationFit.get
    coil.isRatedTotalCoolingCapacityAutosized && coil.isRatedSensibleHeatRatioAutosized && coil.isRatedAirFlowRateAutosized ? 'Yes' : 'No'

If you feel comfortable changing line 114 in the measure.rb file you can try changing it to this.

coil.isGrossRatedTotalCoolingCapacityAtSelectedNominalSpeedLevelAutosized && coil.isRatedAirFlowRateAtSelectedNominalSpeedLevelAutosized  && coil.isRatedWaterFlowRateAtSelectedNominalSpeedLevelAutosized ? 'Yes' : 'No'
