Dear All,
I'm working on a residential apartments project and I'm trying to figure out what ASHRAE 90.1-2007 mandates as maximum lighting power density for this kind of projects. I couldn't find any LPD (W/m2) for any space type of residential apartment. In addition, there's no guidance in the building area method LPD section neither. What approach should be followed? OR where can I find any guidance on LPD of residential apartment units? Does anybody have any ideas on this?
Regards,
Emre

One recommendation is to use building area method instead of space-by-space.

I agree the building area method is the only sure thing.
There is space-by-space for living quarters and dorms that allow 1.1. You could try using those.
There is an old CIR that allowed 2.0 W/sf for this application. Check to see if this made it into the new interpretations.
