Hot water….does the building panel POWER an electric hot water tank in each unit ?
Your total AFTER using table 220.84 is higher ?
Sorry I’m wrong, actually there is no electric hot water heaters, it’s gas.
also yea after using 220.84 and multiplying by .23, it’s higher…
How I calculated the net total demand of the entire apartments:
1. Added all the square footages and multiplied by 3. Added total small appliance and total laundry circuits from all the apartments then used table 220.42.
2. added all the AC units of all apartments
3. added all the appliance circuits fastened in place and multiplied total load by 75%
4. added up all the power of clothes dryers of all the apartments and used 220.54
I then added all the loads in steps 1,2,3,4 to get the answer.
optional method:
1. I added all the apartment demand VA calculated in part 3 from the NEC and then added 8kw for range to each apartment and then I multiplied total VA by .23
