Core & Shell, the applicable ASHRAE Performance Rating Method (ASHRAE
90.1-2004 Appendix G Table G3.1(5)(f)) states that the baseline envelope should
be modeled with existing conditions prior to any retrofit. The envelope
for additions to the existing building should be modeled with the applicable
ASHRAE Building Envelope Requirements table and corresponding Appendix G Table
G3.1(5) requirements.<br>

LEED for existing buildings uses benchmarking for comparison, not energy modeling.<o:p></o:p></p>

<p style='margin-bottom:12.0pt'>Appendix G does specifically state that for
existing buildings being gutted, the Baseline building envelope should be
modeled based on the existing conditions prior to any revisions that are part
of the scope of work being evaluated (Table G3.1(5)(f)). Therefore, if
you are modeling self-shading and adjacent buildings in the proposed case for
an existing building, they should also be modeled in the base case for existing
buildings.<br>
