<p class="MsoNormal"><o:p> </o:p></p>
<p>Dear bldg sim'rs <o:p></o:p></p>
<p>I'm a little concerned that the plug loads I've modelled in my offices are low and could leed to some unwanted usgbc comments.<o:p></o:p></p>
<p>I'm meeting the 25% requirement but the peak load in the offices is 10w/m2. Whilst i dont think this is overly optimistic the reviewers may think otherwise. Has anybody had experience of plug loads being queried in detail?<o:p></o:p></p>
<p>Many thanks<o:p></o:p></p>
<p>Chris<o:p></o:p></p>
