[Equest-users] Hourly space temperature after cooling

[Bishop, Bill]

Hi Paul,
The 75 °F input that you shared below for "Indoor Design Temperature" is the DESIGN-COOL-T which is used for sizing calculations (and is optional when using DOE-2.3). The hourly thermostat setpoint is part of the thermostat schedule so you need to look at the day schedules within the S1 Sys1 (PSZ) Cool Sch.
Regards,
~Bill

Hi David,

Thanks for the answer. I don´t think that explain the data because the system is working most of the time during the year, and a note in the SS-O report shows that the temperature counts are made only for the hours when the fans are on. The cooling schedule matches with the  occupancy schedule.

The set point is 75 °F and the throttle range is 2 °R.

The BEPS report shows that are 155 unmet hours, but the SS-O report gives a value of at least 2505 (adding from 80-85 and above 85).

That SS-O report should be after cooling (it's a "system" report), but it may include some hours when the control system is in setback - it's not only for occupied hours, would that explain your data?



There is a separate module for report variables that you can specify to document any number of internal calculations, including one or more space temperatures - it's been a while since I set one of those up but if you search this community for "report variables" some instructions should pop up.



These can then also be exported to excel, or printed in the *.sim report.

Hi all,



If I open the BEPS Building Energy Performance, there are 155 unmet hours. I would like to get the temperature values throughout the year after cooling, but the only related option that I can see is the SS-O Space Temperature Summary where the temperatures above the set point are much more than the unmet hours. It seems that is the report of the space before cooling.



How could I get the space temperature after cooling to have relation with the unmet hours?
