style='font-size:11.0pt;color:#1F497D'>If you’re looking to start
somewhere…  I know the NEC (NFPA 70) lays out a clear method of
estimating dwelling unit lighting loads within Article 220.  It starts off
seeming high (3W/SF), but there are heavy demand factors that vary with the
total calc’d load following within the same article: i.e. first 3,000 @
100%... 3,000 to 120,000 @ 35% etc…<o:p></o:p></span></font></p>

NEC as an energy modeling resource, I’m unaware of any better direct
source for residential lighting loads… I imagine if you dig hard enough,
one of the ASHRAE handbooks probably has something along these lines as well
that might give you a different sum.<o:p></o:p></span></font></p>

clear thing or two to say regarding what percentage of the lighting load should
end up in a space vs. a plenum when you are talking about different lamp
sources (incandescent vs. CFL…) – something to be aware of if you
