Whoa!<br><br>Hugh differences by design!<br><br>LOADS reports are just that...space heating and cooling loads plus assigned electric loads, which includes occupants, schedules, etc. All at constant thermostat temps for each SPACE. <br><br>SYSTEM loads are the loads on the air-side systems, which are system dependent, and include ventilation loads, exhaust fans, thermostats, economizers, etc. <br><br>PLANT adds yet another layer of equipment, etc.<br><br>Therefore, values from SYSTEMS or PLANT are best used for sizing depending on system type. <br><br>Jeff

<p class="MsoNormal">Dear Bldg-Sim users,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In DOE2 , have any users come across major differences
between building peak cooling loads (in the LS-D reports) and the maximum
cooling loads listed in the SS-D reports?<o:p></o:p></p>
<p class="MsoNormal">I’m troubleshooting equipment sizing in a DOE2 model
and I’m trying nail down some reasonable explanations for the disparities
in the loads. <o:p></o:p></p>
<p class="MsoNormal">I would appreciate any words of wisdom.<o:p></o:p></p>
