<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Can
anyone with experience showing compliance with ASHRAE 90.1-2004 section 9.4.5
enlighten me as how the baseline calculation should be done? <o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>The
confusion I’m having is with the definition of an illuminated wall or surface
length when applying the 5.0 W/linear foot allowance for building façades.
How is the lineal footage of an illuminated wall determined? <o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>For
example, if a 100’ wide wall has one exterior lighting fixture on it at the
center, is the entire wall considered to be illuminated and thus the baseline
lighting power allowance is 500W? Or is there some method of determining
the actual portion of the wall that is illuminated?<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>This
came up on a LEED project where I had applied table 9.4.5 as conservatively as
