I agree with Nick. There does seem to be some confusion. Omar, please send us clarification as you are able. Daylighting is daylighting and there are inputs within eQUEST to use. I have heard, not remembering where at this moment, that the only thing to do re daylighting in the wizards is to turn it on. Say daylighting = yes.<br>
<br>What I read & responded to with the schedule response was on/off control for bathrooms. That's an occupancy sensor and a schedule modification. Depending on who you are modeling for, a reduction in schedule is appropriate. View Oregon SEED Appendix L for info.<br>
<br>In sum, I read Omar's query as a two parter: one part occ sensor, one part daylighting.<br><br>As always, I am available for correction.<br><br>Regards,<br>Carol<br><br><div class="gmail_quote">On Tue, May 11, 2010 at 1:30 PM, Nick Caton <span dir="ltr"><<a href="mailto:ncaton@smithboucher.com">ncaton@smithboucher.com</a>></span> wrote:<br>

<br>
Some of what you want to do e.g. on/off using an occupancy is best done using a
schedule. A 15 % reduction is always acceptable, and you could argue for more
if the case can be made for it. For instance if your schedule value for noon is
.80 just reduce it by (.80*(1-.15)). If you know that the reduction should be
more than 15 % and can clearly state why then you should.<br>
<br>
I use specify exact site coordinates, on screen 1 of 25 in the DD wizard, so
that I am sure the polygon I am creating is where I want it, I set it to 0,0,0
for the 1st polygon, lower left corner, and go from there. Try putting in the
exact coordinates for the lower left corner of each space.<br>
<br>
