<p class="MsoNormal"><span style="color:#1F497D"> </span></p><p class="MsoNormal"><span style="color:#1F497D">Basically you’re allowed to reduce the lighting by the percentage listed in the above table, 10% for most buildings. You can do this by either reducing the lighting power input for the spaces by 10% under the Internal Loads tab or create a lighting occupancy sensor schedule that has hourly fractions that are 10% less than your regular lighting schedule. You also need to make sure that you apply this lighting credit to any spaces that are required by minimum code to have automatic lighting controls specified under Section 9.4.1. Table G3.1 Number 6 has a good explanation of this process for the baseline and proposed building.</span></p>

</div></div><div><div></div><div class="h5"><p class="MsoNormal"> </p><p class="MsoNormal">Hi All,</p><p class="MsoNormal"> </p><p class="MsoNormal">I just got back comments on my models for a LEED project and the reviewer commented that I needed to account for occupancy sensors. I had done this by switching the lighting schedule to the occupancy schedule in rooms with occupancy sensors, does anyone know if this is an appropriate way to model occupancy sensors? Is there a tool built into equest that allows you to account for them a different way?</p>
