<p class="MsoNormal"><span style="color:#1F497D">Lets assume Option 1 below for the Baseline Model: (no power factor adjustments to the Table 9.6.1 lighting power densities of spaces requiring Mandatory automated controls of ASHRAE 90.1 Section 9.4).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Option A: Apply the Power Adjustments of Table G3.2 to the installed lighting power densities in all spaces installed with, but NOT requiring, mandatory automated controls per ASHRAE 90.1, Section 9.4. Assume
the same typical schedule of ramping up in the morning, dipping for lunch, and ramping down after closing as the Baseline.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Option B: Apply the Power Adjustments of Table G3.2 to the installed lighting power densities in ALL spaces installed with automated controls. Assume the same typical schedule of ramping up in the morning,
dipping for lunch, and ramping down after closing as the Baseline.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Option A seems the logical approach by taking credit in only the additional spaces. That means the Power Adjustments for Automatic Lighting Controls in Table G3.2 applies only to spaces not requiring automatic
mandatory controls of Section 9.4.<o:p></o:p></span></p>

<p class="MsoNormal">I would like the opinions of others regarding the interpretation of the Baseline Building Performance Lighting of Table G3.1 in Appendix G.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Table G3.1, Item 6. Baseline Lighting, last sentence states the following;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">“No automatic lighting controls (e.g. programmable controls or automatic controls for daylighting utilization) shall be modeled in the baseline building design, as the lighting schedules used are understood to reflect the mandatory control
requirement in this standard.”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am questioning 2 ways to interpret this in the model. I will use a 10,000 sf office building with typical business hours of operation from 8 am to 6 pm. Most spaces are required to have automatic lighting controls as specified in the
Mandatory Provisions of Section 9.4 (ASHREA 90.1).<o:p></o:p></p>

in ASHRAE 90.1. with the 10% Power Adjustment factor of Table G3.2 applied to the lighting demand of spaces required to have mandatory controls of Section 9.4.<o:p></o:p></p>
<p class="msolistparagraph0"><o:p> </o:p></p>
<p class="MsoNormal">I have typically used option 1 without question from the USGBC which increases savings, but was wondering how others have interpreted it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
