I have been involved in a couple of projects where the overhead lighting has been designed to have a low ambient light level, with task lighting provided for the work spaces. This is because most people in the offices will be working at computers, and not need high levels of lighting.<br>
<br>For one or two projects, I included task lighting in the proposed case, but not in the base case. I received comments from the LEED reviewer that all process lighting (including task lights) must be the same between the proposed and the baseline. This is regardless of the fact that the presence of task lights allowed us to reduce the installed lighting power.<br>
<br>Ever since, I've been including task lights equally in the proposed and baseline cases, and had no comments on this approach.<br><br>--<br>Karen<br><br><div class="gmail_quote">On Sat, Mar 13, 2010 at 10:58 AM, Gerard Hazel <span dir="ltr"><<a href="mailto:ghazel@aol.com">ghazel@aol.com</a>></span> wrote:<br>

<p class="MsoNormal" style="margin-left: 0.5in;"><font face="Calibri" size="2"><span style="font-size: 11pt;">I just received a question from GBCI on a LEED CI
project related to lighting power density. It was my understanding that per
ASHRAE 90.1-2004 std. <u>plugged in</u> task lights are exempted from the
overall lighting power density calculations. However, our review came back
saying that task lights should be included in the overall calculations. Is this
true? Has the standard changed recently?</span></font></p>
