Daylighting an auditorium to 10 FC

[Coffeefiend]

Afternoon everyone,
I'm working on a project that requires me to daylight an auditorium to 10 FC minimum. I know the make and model of my windows, the placement on the wall, and the size of the auditorium. Does anyknow know of a formula that I cna use to determine how many windows I'm going to need to light the space correctly? Any help would be appriciated. Thanks very much!

There are a lot of variables aren't there. My suggestion would be to model the auditorium, either physically or using some environmental software. It sounds like they just want enough light to easily see where they are going!

Here is a previous discussion and a link I had found then:

also a book called "Heating, Cooling, Lighting -Design Methods for Architects" is good
