<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.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The LEED 2009-NC Guide says:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> "To achieve points using this credit, the proposed
design must meet the following criteria: <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></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).<o:p></o:p></p>
<p class=MsoNormal>-Inclusion of all the energy costs within and associated
with the building project.<o:p></o:p></p>
<p class=MsoNormal>-Compare against a baseline building that complies with
Appendix G...... (we all know about that part).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></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.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Does anyone have any insights or suggestions?<o:p></o:p></p>
<p class=MsoNormal><br>
Thanks!<o:p></o:p></p>
