over here in england we are required, on new build commercial/industrial and refurbishment works, on lighting and electrical works to ensure that 80% of new lighting is energy efficient and complies with lighting directives.
You can get most of the information you wouyld need from the lamp manufacturer and the light fitting manufacturer,
allmost all fitting makers will help, either with a design package or even sending out a lighting engineer to work out watt you need and were, and usually its free, as they want your business,
talk to your supply house and see what they say.
also, do you have anyhting within the NEC regarding this, (i cant check myself as i havent got a copy, yet),
