  In high-granularity calorimetry, as proposed for detectors at future Higgs
factories, the requirements on electronics can have a strong impact on the
design of the detector, especially via the cooling and acquisition systems.
This project aims to establish the typical fluxes in the calorimeters:
deposited energy, number of cells above the electronics threshold, additional
heat, and associated data, etc. Here, a software package is presented which
outputs histograms for different selections of the calorimeter components from
fully simulated physics and background events. The ILD calorimeter system is
taken as a specific example, upon which different histograms are obtained for
representative parts of the calorimeter and for various machine configurations.
Examples of histograms are shown, along with all details of the data used and
the simulation.
