envelope. e.g. the proposed building might have a well insulated envelope and may
not call for heating during night time to maintain the thermostat set back. Whereas,
the baseline building (or a zone in the building) might call for heating during
night time and thus would result in the fans cycling on during night time.<o:p></o:p></span></p>

<p class=MsoNormal>Hello All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Quick question for you. How are the total run hours summated
in the SS-R reports? I have two models baseline and proposed with the same fan
schedules however the run hours are different. I was under the impression that
the run hours are directly related to the times in which the fans are scheduled
off/on. Perhaps this is still the case and something else has been altered
between my runs. Thank you for the clarification. <o:p></o:p></p>

<p class=MsoNormal>Regards,<o:p></o:p></p>
