Hello members, this is my first time doing this electrical calculations for Hotels....i need some help please !!

I need to determine/ estimate element of electrical system for 7 floors building (mixture of commercial and Hotels). Voltage system is 240V

I did a quick calculation for the Hotel part:
- 28 rooms per floor, 3 floors have identical floor layout each 19450.4 sq ft per floor.
4th floor : 28 rooms with Total Area 19450.4 sq ft.
Table 220.12 lighting load is 3VA per sq ft : 19450.4 sq ft x 3 VA per sq ft = 58,351VA
Table 220.42 1st 20k at 50% 20,000VA = 10,000
next 80k at 40% 38,351VA = 15340.4
Calculated load = 10,000 + 15340.4 = 25KVA

The question is this calculated load (25kva) is only for general lighting or receptacles are included? since i used 3VA per sq ft.....

How do i calculate, the small appliances, feeder and conductor size?

Thank in advance
Mustafe
