Hi , I am modeling a LEED model for data center, now for vault spaces I am assuming a setpoint of 99 F for cooling and 20 F for heating, what should be band to consider a vault space UMLH? for office we consider 2.5 F based on heating and cooling setpoint what to do in this case?
Thanks in advance

Temperature set point are not regulated by 90.1 so you can set them as you wish within reason. I don't think that a 99F set point for cooling is reasonable. Given the internal load don't think you need to be concerned about the heating. I don't understand your second question.

Thanks Marcus for the reply, 99 F is the setpoint we are assuming for Data Hall spaces since the Return air temp is 99F, in reality there will be hot aisle and cold aisle, we cant model that in a software so we are going with modeling a vault as 1 space. Now when I create a report for LEED it shows UMLH, for Office spaces the bounds are +- 2.5 F so lets say if the setpoint in office is 75 F anytime it goes above 77.5 it will be an UMLH, how to figure out that bound for a data center?
TIA
