Dear all,

I am modelling a hospital which has humidification within the AHUs. The required steam is produced using natural gas, which means I need an Exceptional Calculation because the software used allows only electric humidifiers.

I read in the forum that humidifcation is a process load and as such the consumption must be the same between the two buildings. Can I add the energy consumption later on after the simulation in the calculator? Or should I also calculate the humidifcation for the baseline building the same way I will for the proposed building? If I did it this way, I think the results for the two buildings would be different (different air flows) and therefore not energy neutral, as required for process loads.

Thank you all.
