Two chillers changes part load relationships a lot.
Lower water temp to the chilled beams probably affects their performance, too, but I suspect the bigger impact will be on the chiller performance.
I think I’ll go with the one chiller approach.
This might be a nice item to add to the development list, if it’s not already on it!

In E+, you either end up needing to use two separate chilled water loops (and two chillers), or ignore the higher temp water for the beams and use one supply temperature.
