didn't say whether you were modeling an ASHRAE 90.1 or LEED project. If so
automatic lighting shutoff controls are a mandatory requirement for areas
not operated 24/7 according to Sec. 9.4.1. If you provide occupancy sensors
for zone level control you can show savings for occupancy
sensors according to Table G3.2 in Appendix G. Methods allowed include
reduction of the connected LPD or a reduction in the hourly lighting
schedules.</FONT></SPAN></DIV>

Sensors<BR><BR></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=789331820-16112007>Has anyone tried
to model occupancy sensors for the lighting system in
E-Quest?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=789331820-16112007>I have a rather
large building (135,000 sq ft) inwhich 30% or so is opperated 24/7 and the
rest is a typical office building. We are including occupancy sensors in
each room but we are unsure how to quantify the savings those sensors may
provide. The only way I understand to show savings is to reduce the
lighting schedules, but I do not know how much. I am finding that
lighting is approximately 30% to 35% of total building energy consumption and
savings here could mean a decent cost savings. Has any one had any
experiance with this? I would appreciate any help you can give
me.</SPAN></FONT></DIV>
