[Bldg-sim] Supply air temp reset - ASHRAE 90.1 - Appr G

[Julia Beabout]

All,
RE: ASHRAE 90.1, App G, Article G.4.2.3.1.2, Supply Air Reset

Addendum A revised this article to say: "The air temperature for cooling shall be rest higher by 5F under the minimum cooling load conditions".
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.

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?

Would appreciate any feedback anyone has on this, especially with respect to doing a LEED energy model.
Thanks.
Julia
