ASHRAE 90.1 par. G3.1.2.4 doesn’t really cover this for System 8 and leaves it open to have the baseline as “Cycle on Any.” However with PFP boxes, you could also argue it should be “Zone fans only” since they are part of System 8. There is no clear direction one way or the other in ASHRAE that we can find. Depending what you choose, it can be a major energy factor on the baseline. What’s the right answer? The proposed design is Zone Fans only if that makes any difference.<o:p></o:p></p><p class=MsoNormal>Thanks in advance,<o:p></o:p></p><p class=MsoNormal>Gerry Hazel<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Gerard Hazel <o:p></o:p></p><p class=MsoNormal>M&E Engineers, Inc.<o:p></o:p></p><p class=MsoNormal>908-526-5700 x14<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
