By making all loads 100% 24/7 you will drive energy consumption way up and dilute potential savings with high annual costs. LEED requires that systems cycle with occupancy and using this schedule indicates that all spaces are occupied all the time, therefore systems will run all the time. This schedule is ideal for load calculations as it presents you with a worst case scenario… 100% of loads for cooling and 0% for heating, however this will likely never be the case during actual operation. Personally, I like to create my own schedules that still include 100% 24/7 for cooling design, but weekday/weekend schedules that reflect actual occupancy. Keep in mind that heating design should always be zero, as you don’t want people/light/receptacle loads to help heat the space when designing for worst case scenario. Ventilation schedules however should be set to 100% for heating design however, as this needs to be factored in for your heating worst case scenario.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Hope that helps!<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Best,<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Jay<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'>Jason Dietterick</span><br><span style='font-size:10.0pt'>Associate, Energy Modeler<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-variant:small-caps'>The Stone House Group</span><span style='font-size:10.0pt'><br>DIRECT DIAL 484.548.4007</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt'><o:p> </o:p></span></p><p class=MsoNormal><br><span style='font-size:9.0pt'>301 Broadway Ave<br>Bethlehem, PA 18015<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:9.0pt'>Tel 610.868.9600<br>Fax 610.868.2272<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> trace-users-bounces@lists.onebuilding.org [mailto:trace-users-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Ben<br><b>Sent:</b> Monday, September 16, 2013 11:16 AM<br><b>To:</b> trace-users@lists.onebuilding.org<br><b>Subject:</b> [Trace-users] Cooling Only (Design) Schedules and LEED Energy Modeling<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I am working on an energy model for a LEED project using Trace, it’s my first one, and I was going through the error comments Trace generates and I saw a warning about using the Cooling Only (Design) schedule.
