<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I'm confused as to whether any
exterior lighting power can differ between the proposed & baseline models.
Any one have any experience from EA Cr1 submissions?<o:p></o:p></SPAN></FONT>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The Users Manual for App G states at
the end of the "Baseline Lighting" Section, ".... credit may be taken for
improvements in exterior lighting efficacy or wattage... the proposed building
can take credit for a more efficient system." So proposed parking lot lighting
at 0.08 W/sf or whatever would be compared to a baseline of parking lot lighting
at 0.15 W/sf. I believe façade lighting must be the same in both, as these are
"non-tradable surfaces" in Chapter Six.<o:p></o:p></SPAN></FONT> </P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">But an apparently poorly-considered
Credit Ruling from 4/25/07 simply states "No. Appendix G does not allow
trade-offs for exterior lighting," directly contradicting the
UM.<o:p></o:p></SPAN></FONT> </P>
