<DIV>RE: ASHRAE 90.1, App G, Article G.4.2.3.1.2, Supply Air Reset</DIV>
<DIV> </DIV>
<DIV>Addendum A revised this article to say: "The air temperature for cooling shall be rest higher by 5F under the minimum cooling load conditions".</DIV>
<DIV>This sounds to me like they are saying the supply air temperature should be reset based on outdoor air temperature. This would be quite a change in concept from the original version of this article which required the supply air temperature to be reset based zone demand.</DIV>
<DIV> </DIV>
<DIV>Are others out there interpretting the revised addendum A version of this article the same way I am....i.e. that the SAT should now be reset based on outdoor air temperature? Or, are people still interpretting it as the SAT should be reset based on zone demand?</DIV>
<DIV> </DIV>
<DIV>Would appreciate any feedback anyone has on this, especially with respect to doing a LEED energy model.</DIV>
<DIV>Thanks.</DIV>
