I would like to take into account internal objects in a room as a volume that reduces the total volume to consider. Therefore, I would like to know how can I change the volume input through the IDF file, also if there are other solutions, considering that I don't want to change the amount of the external surface.
Thank you, I did it!
Also, is it possible to consider the volume as a variable parameter that can vary every hour or that depends on a schedule?
Actually, I'm trying to consider also the people's volume as a factor that influences the total volume input. Therefore, I would need to give a schedule to the volume or to vary the volume every hour.
