<div>Hi Nick, </div><div> </div><div>I can not agree with you more. Ashraf will have to answer why such 40% reduction is not reflected in the original energy modeling. </div><div> </div><div>The only divergence is the example with which you believe the appliances fall into "plug loads" whereas I believe they could be "process one". Again, it really depends on which LEED system (2009 or older version) we are using. No process loads will be included in modeling under the old LEED system. In another words, no penalty for heating due to reduced process load. However, your methodology is accurate under the new LEED since both plug load and process load should be involved in energy modeling. </div>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">I suppose I have a more general understanding that “exceptional calculations” exist for when you have designed energy saving measures which cannot be credited following 90.1/LEED “to the letter.”<u></u><u></u></span></p>

These calculations and a brief description of how they were compiled and applied to the proposed model would be uploaded and referenced alongside the modeling templates. Perhaps my terminology is off and this is not really an “exceptional calculation?”<u></u><u></u></span></p>

It’s possible an LPD reduction would not adequately reflect whatever is really going on.<u></u><u></u></span></p>

</div><div class="im"><p class="MsoNormal"><u></u> <u></u></p><div><p class="MsoNormal">Well, my understanding is that exceptional calculation is used to document meansres that may not be adequately modelled in a simulaiton program.

<p class="MsoNormal"><span style="font-size: 11pt;">A reduction of lighting consumption is claimed to reduce heating consumption?</span><u></u><u></u></p><p class="MsoNormal"><span style="font-size: 11pt;"> </span><u></u><u></u></p>
<p class="MsoNormal"><span style="font-size: 11pt;">As you say, lights are an internal heat source to some extent… reducing the lighting energy consumed by a significant fraction should cause a relative increase in heating and a reduction of cooling energies, right? I’m going to assume the reviewer’s vocabulary is simply flipped around and this is the point they were trying to make: Changing lighting should affect heating/cooling consumptions.</span><u></u><u></u></p>
<p class="MsoNormal"><span style="font-size: 11pt;"> </span><u></u><u></u></p><p class="MsoNormal"><span style="font-size: 11pt;">As to how you document this – It would seem simplest if you simply worked your “exceptionally calculated” reduction back into the model. From your description I don’t know exactly what your “hard-wiring” strategy is that’s chopping off 40%, but applying a factor to the space LPD’s may be a decent approach. You could then demonstrate before/after results showing lighting/heating/cooling consumptions moving about by setting up a parametric run and using those reports.</span><u></u><u></u></p>
