This is likely an EnergyPlus bug too.

Possible Solution

Fix the method.

Details

Environment

• Mac 14.4 but also occurred on Windows too.
• Occurred on 3.6 and now on 3.7

Context

Students had to model baseboards and hard size their models last semester but could not find the capacity.

The ZoneHVACBaseboardConvectiveWater object does not contain any autosizable fields, so I believe we wouldn't expect it to have a “applySizingValues” method.

You are right, there doesn't appear to be a reported "Design Size Heating Design Capacity" field for the ZoneHVAC:Baseboard:Convective:Water object:

Looks like there's an open EnergyPlus issue about this: https://github.com/NREL/EnergyPlus/issues/4957
