Here is a single line diagram of an electrical design for buildings.

I started doing the illumination calculation (zonal cavity method) and layouted the necessary number of lighitng fixtures on the drawing.
Now I wanted to wire them with switches of course and connect them to a power source. So by wiring you group the fixtures and be connected to a specific circuit. There would only be limited number of fixtures to be connected to a certain circuit depending on the capacity of the circuit breakers.
My problem is that I am not sure that given that Single line diagram above, how to calculate the total load to be connected to a certain circuit and thus the number of fixtures to be connected. There are 5 circuits shown on the diagram.
For example, i have a fixture that says" 4x36 Watts fluorescent lamp". So how many lamps should be connected to circuit one(the on the leftmost side on the diagram).
Please teach me a general solution to solve this. Thank you very much...
