<ul style="margin-top:0in" type="disc">
<li class="gmail-m_2250357236898809084MsoListParagraph" style="margin-left:0in">Table G3.1 says that the baseline case is to use table G3.7 to define space by space LPD, but the proposed has to comply with section 9.1.3. There’s a big difference between maximum
allowed LPD between the two tables, for example G3.7 calls for open Office areas at 1.1 W/sf but table 9.6.1 says 0.81 W/sf.
<u></u><u></u></li><li class="gmail-m_2250357236898809084MsoListParagraph" style="margin-left:0in">Baseline Wall insulation for climate zone 5b, per table G3.1 and G3.4-5 is to be simulated at a U value of 0.084. The proposed case must be under 0.055 per table 5.5-5.
<u></u><u></u></li></ul>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Appendix G now has tables for envelope properties, equipment efficiencies and lighting power densities which all conflict with what we’re used to finding in sections 5, 6 and 9 in previous iterations of the standard. Reading table G3.1
it seems clear that they want us to use the appendix G tables to define the baseline and not the tables in the main sections, but this makes no sense to me.
