Re: Table 220.3(A) General Lighting Loads by Occupancy
Since this facility has squash courts, why not use the 2 VA per ft^2 allowed for “court rooms”? (Sorry, couldn’t resist).
When I get involved in a project for which the occupancy is not listed on Table 220.3(A), I try to find the nearest logical match. In your case, I would use the 1 VA per ft^2 allowed for “auditoriums.” Then I would calculate the actual VA for the selected fixtures (using the fixture rating, even if the selected light bulbs use a lower amount of power). I would submit as my final calculation whichever of these two gives the higher load.
