Subject: [Bldg-sim] Hot Water Supply Temperature Reset in eQuest
 

Can anyone share some experience on how to reset hot water supply
temperature as required in G3.1.3.4 of ASHRAE 90.1 - 2004 in eQuest? 
 
"Hot water supply temperature shall be reset based on outdoor dry bulb
temperature using the following schedule: 180F at 20F and below, 150F at
50F and above and ramped linearly between 180F and 150F at temperature
between 20F and 50F."
 
Thank you,
 
Weixiu Kong
