Humidity capacity is a function of construction materials and indoor furniture. I mean what you have in your zone like wood construction for walls or ceramic tile which have different moisture absorbance capacity is really important to deal with this value. But there is only one section to change that value for all structure we have. How is application of different Humidity capacity multipliers for each zones possible if I want to use for each zones which have different materials?

I'm going to tag this for EnergyPlus as most OpenStudio users probably have not altered the default capacitance, although ZoneCapacitanceMultiplierResearchSpecial is in the API for those who want to write a measure to alter it.

You could use characteristics of surface and internal mass objects to come up with a weighted average multiplier to use for the entire building; expert EnergyPlus users may have some ideas? EMS?

Might be worth doing sensitivity analysis on this to see how much of an issue a global multiplier is vs. zone specific, before investing too much effort.
