<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=728103223-31102006>We ran
into a similar question on a LEED C&S project in Seattle. We submitted a CIR
to USGBC to allow for energy savings, after the construction, for a TI
build-out to code. In our case, the lighting power density would, by Seattle
code, be less than the LPD for ASHRAE code. Because the maximum LPD would
be code-required, and because this LPD is less than the ASHRAE standard, the
savings was allowed. Here is the text of the CIR and subsequent
ruling.</SPAN></FONT></DIV>

The tenants will have to meet the WSEC for the<SPAN class=728103223-31102006>

BLDG-SIM@GARD.COM<BR><B>Subject:</B> [BLDG-SIM] LEED Core&Shell simulation
and lighting<BR><BR></FONT></DIV>I am a bit fuzzy on how to define the design
and budget building lighting loads for LEED C&S. With most core and
shell projects, the lighting is minimal - waiting for the TI to design the
lighting. If that is the case with a specific C&S project, then I
assume the lighting is not fully designed then I assume that table 11.3.1 1(c)
applies:<BR><FONT face="Times New Roman, Times" size=2>(c) When the <I>energy
cost budget </I>method is applied to buildings in which<BR>energy-related
features have not yet been designed (e.g., a lighting system),<BR>those
yet-to-be-designed features shall be described in the <I>proposed design
</I>so<BR>that they minimally comply with applicable mandatory and
prescriptive<BR>requirements from Sections 5 through 10. Where the space
classification for a<BR>building is not known, the building shall be categorized
as an office building.<BR><BR></FONT>In this case, then it would seem that there
is no advantage to trying to design an efficient Core and Shell lighting
design? Any thoughts greatly appreciated.<BR><BR><BR><BR><BR><X-SIGSEP>
