<div>Well, my understanding is that exceptional calculation is used to document meansres that may not be adequately modelled in a simulaiton program. Some examples are lab exhaust system, appliance efficiencies in high-rise residential building, etc. How do you define your hard-wired lighting calculation from this point of view? </div>
<div> </div><div>Remodeling with reduded LPD is necessary provided your hard-wired lighting reduction affects internal heat gain and you would expect more heating energy in this manner. I guess it is what the reviewer expect to see unless you can prove him/her that your reduction will not trigger heating/cooling energy variation. </div>

<div lang="EN-US" vlink="purple" link="blue"><div><p class="MsoNormal"><span style="font-size: 11pt;">I think something is missing in the story here…<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size: 11pt;"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size: 11pt;">A reduction of lighting consumption is claimed to reduce heating consumption?<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size: 11pt;"><u></u> <u></u></span></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.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size: 11pt;"><u></u> <u></u></span></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.<u></u><u></u></span></p>
