<div dir="ltr">Hi Matt,<div><br></div><div>The baseline building components referenced in Appendix G of ASHRAE 90.1-2016 are equivalent to ASHRAE 90.1-2004 levels, which is why the baseline wall assemblies and other components in the same appendix are much worse than the ones in the numbered sections (these are the prescriptive components for 2016). The reason for this is to avoid having to create different versions of the baseline model each time a triennial of 90.1 is released (which was the case up until now). The proposed design will always be compared to the 2004 modeling baseline and the results will be adjusted relative to the respective version of ASHRAE 90.1 using Building Performance Factors (BPFs), Performance Cost Index (PCI), and other new metrics. See 90.1-2016 4.2.1.1 for more info.</div><div><br></div><div>Kind regards,</div><div>Calvin</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 16, 2019 at 1:49 AM Javed Iqbal via Equest-users <<a href="mailto:equest-users@lists.onebuilding.org">equest-users@lists.onebuilding.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;color:rgb(0,0,0)">Hello Matt,</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;color:rgb(0,0,0)"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;color:rgb(0,0,0)"><font color="#000000" face="arial, helvetica, sans-serif">- ASHRAE 90.1-2016, section G1.2.1 explicitly says that ' </font><i style="color:rgb(34,34,34)"><span style="font-family:Arial,Helvetica,sans-serif">The interior lighting power shall not exceed the interior lighting power allowance </span><span style="font-family:Arial,Helvetica,sans-serif">determined using either Tables G3.7 or G3.8 and the <b>methodology</b> </span></i><i style="font-family:Arial,Helvetica,sans-serif;color:rgb(34,34,34)">described in Sections 9.5.1 and 9.6.1'</i><span style="font-family:Arial,Helvetica,sans-serif;color:rgb(34,34,34)">.

<p class="MsoNormal">Hi all,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">This is my first project using ASHRAE 90.1 2016 and I’m finding some odd instructions in Appendix G.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">A couple examples-<u></u><u></u></p>
<ul style="margin-top:0in" type="disc">
<li 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 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.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I feel like I’m taking crazy pills…can anyone shine some light on this?
