In the past, it was common to apply a 10% reduction in usage for areas which used an occupancy sensor. That reduction is someone's best estimate, but is clearly an approximation because every building will differ somewhat.</div><div class="gmail_default" style="font-size:large"><br></div><div class="gmail_default" style="font-size:large">No one knows how occupants will <u>actually </u>use the available controls, especially before the building is constructed. That means you must create your best estimate of that usage in your model. The 90.1 User Manual has "Estimated Operating and Occupancy Schedules" and I show one of them below. That's a helpful place to start and might be all you need, unless your client gives detailed operating information.</div><div class="gmail_default" style="font-size:large"><br></div><div class="gmail_default" style="font-size:large"><img src="cid:ii_160c7e128fe7b91d" alt="Inline image 1" style="margin-right: 0px;"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jan 5, 2018 at 11:36 AM, julien dutel via Bldg-sim <span dir="ltr"><<a href="mailto:bldg-sim@lists.onebuilding.org" target="_blank">bldg-sim@lists.onebuilding.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
