I am designing the electrical system for a high-rise residential tower. Per NEC 220.84, I can apply a demand factor to my main switchboard, depending on the number of dwelling units that are being fed by the switchboard.
Unfortunately, Revit seems to have no way to calculate demand loads in this manner. Revit can calculate demand loads by quantity of fixtures, or by load, but not by quantity of dwelling units. For now, I have to use Excel to create my switchboard panel schedule.
It would be useful for Revit to have the ability to assign demand loads to electrical equipment, instead of electrical fixtures (at the user's discretion). If this were the case, then I could assign my dwelling unit panelboards with a "Dwelling Unit" load classification, and the switchboard would be able to count the number of "Dwelling Unit" panelboards, and apply the right demand factor, rather than incorrectly passing the "receptacle" or "lighting" demand factors down to the main switchboard.
