I agree with Bill. I, too, am not a LEED reviewer but I have been an energy code reviewer and the interpretation was always that the code requirements for insulation were for new buildings and existing building where the wall was going to be modified. That makes sense where requiring an existing building to have all walls modified would not. LEED supports the reuse of existing materials as well as energy efficiency so forcing a change would seem counter<br>

<p class="MsoNormal"><span style="font-size: 10pt; color: navy;">I’ll argue that you should not need to upgrade the envelope of an
existing building to meet Section 5.4 except where you are creating new envelope
surfaces (such as new building additions). Likewise, you should not need to
improve the efficiency of existing equipment per Section 6.4, as long as you
are not replacing it with new. The scope of Standard 90.1-2007 (and -2004)
includes:</span></p>

<p class="MsoNormal"> </p>
<p class="MsoNormal">There is a debate going on in my office currently, regarding
existing buildings and their envelopes and what is required for EA Prerequisite
2.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The LEED 2009-NC Guide says:</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"> "To achieve points using this credit, the
proposed design must meet the following criteria: </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">-Comply with the mandatory provisions (Sections 5.4, 6.4,
7.4, 8.4, 9.4 and 10.4) in Standard 90.1-2007 (with errata but without
addenda).</p>
<p class="MsoNormal">-Inclusion of all the energy costs within and associated
with the building project.</p>
<p class="MsoNormal">-Compare against a baseline building that complies with
Appendix G...... (we all know about that part).</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">What's got the debate going is that part about Complying
with the mandatory provisions (particularly Section 5.4). Now, we do a
lot of existing buildings, wherein no insulation is added. I know that,
when creating the energy model, that when modeling existing buildings, or
portions of existing buildings, where no alterations are being made, that both
the Proposed and Baseline building are modeled with the as-existing
construction. However, it was brought up that, as the LEED Guide
specifically calls out Section 5.4 (which I've been unable to find any mention
of existing buildings), was intentional, to for any would-be LEED projects to
bring their existing envelope constructions up to Section 5.4
requirements. I've looked over the CIRs and didn't find anything really
telling.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Does anyone have any insights or suggestions?</p>
<p class="MsoNormal"><br>
Thanks!</p>
