Electrical Design for Large Building

Yes. There are also schools that teach this.

A Google search will reveal many of them.

Yes,..there are books for electrical installation in the book shops in shopping mall.

Methinks you are sadly mistaken. The bookstore that acted as a library/latte shop for men as their S.O's shopped, are a thing of the the past. If you are a book store, ya gots ta sell something more than a couple of coffees and people normally don't want to pay 35 plus for a donut smudged, coffee stained book. ( I can provide my own coffee stains and chocolate smudges, thank you just the same).

So maybe just ask the folks who sell $7 dollar coffee what they require and multiply accordingly.

But, his shopping mall hasn't been built yet.

The prerequisite class for ED102 is ED101, Electrical Design for a Small Building.

Talk to the suppliers, they will sometimes help you design to your requirements. For example, my father was the Foreman of the Square D manufacturing facility in Los Angeles. The power requirements for the distribution system would be delivered to Square D and their engineers would then design the panels for the entire mall.

And then the engineers would come out into the plant and ask him how to route the buss bars, etc.Preview Comment

Best way to learn design is "join a design office".

Is this UN sanctioned? Does the UN offer design office?

Design office in this instance is one which design civil,plumbing,mechanical,electrical services in buildings.Why do you drag UN(puppet) into this?.

Get back to an Engineering college.

or a coaching centre to the design course.
