Nick,<br><br>For occupancy sensors, I have always reduced the % on in the lighting schedules, never the installed LPD. Here's a thread from way back discussing how to do this:<a href="http://www.gard.com/ml/bldg-sim-archive/msg02168.html">http://www.gard.com/ml/bldg-sim-archive/msg02168.html</a>. <br>
<br>If the methodology has changed to reducing the LPD by 15% I'd like to know. It would be much easier and I'd love to be wrong!<br><br>How are others doing this?<br><br>Carol<br><br><div class="gmail_quote">On Mon, Jul 12, 2010 at 7:42 AM, Nick Caton <span dir="ltr"><<a href="mailto:ncaton@smithboucher.com">ncaton@smithboucher.com</a>></span> wrote:<br>

<p class="MsoNormal" style="margin-bottom: 12pt;">For the spaces that don't
require occupancy sensors you can show savings by modifying the lighting
schedule. I think a 15% reduction is allowed, but verify that by looking in
Appendix G where it tells you what you can do and when. In fact it would be good
for you to make a practice of researching the answers to these types of
questions yourself and save the more complicated questions for the listserv. It
is important to respect everyone's time and do diligence by trying to find the
answers yourself. I know it's a lot to process at first but you will benefit
from the study.<br>
