from the entire Chapter 9 requirements (2004 uses the term "living unit"). So I
think the 1.1 W/sf or 1.0 W/sf does not apply to the dorm room. My opinion is
that the lpd in the baseline dorm room should be the same as in the proposed
building unless the applicant convinces the "rating authority" that what they
are proposing is a "significant verifiable departure from documented
conventional practice", per Appendix G. </SPAN></FONT></DIV>

style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'">Bill,
it sounds like you are applying the exception but I don’t think it applies here
since the lights in the dorm rooms are controlled on fixed wall-switches, and
not connected via receptacles. My understanding is that the proposed
design should be modeled with W/sf as shown on the plans (however small it is)
and the baseline be modeled with 1.0 W/sf as determined by the Building Area
Method. Note that if the Space-by-Space method were used the allowable
baseline W/sf for the dormitory living areas is 1.1 W/sf. <o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN
style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'">If
the lighting design has LPD less than baseline and fixtures are hard-wired, then
credit should be taken.<o:p></o:p></SPAN></P>

G3.1, No. 6(d) states: “Lighting system power shall include all lighting system

I would implement this is to assign the same W/ft<SUP>2</SUP> lighting to all
dorm rooms on a different meter in both the baseline and proposed designs. Then
I would subtract the kWh of that meter from the building performance. You could
still show lighting savings if you do the space-by-space method for both designs
(assuming the lighting in your corridors and common areas is
efficient).<o:p></o:p></SPAN></P>
