8760 Schedule in Ironbug

[Elliot_Glassman]

Is there a way to create an annual schedule with 8760 unique values?

Hi,@Elliot_Glassman You can use honeybee to create an annual schedule with 8760 unique values then assign to ironbug
Here is the example file created by @MingboPeng

Ironbug doesn’t seem to like the csv 8760 annual schedules from honeybee…they seem to need to the ironbug schedule components but those are configured for daily/weekly values

OpenStudio 2.5 doesn’t have Schedule:File object which is needed for csv files. But it has been added after OS 2.7, I will add Schedule:File later with OS2.8.

I have added ScheduleFile in this update patch, you can download and test it if anyone is interested in.

Ok @MaxMarschall I checked with OpenStudio team about this issue, there were some updates on dealing with ScheduleFile and ExternalFile object. I just updated the ironbug for this, and did some tests: Ironbug.20200429.zip (288.9 KB) 20200429_ScheduleFile_Example.gh (562.0 KB) Here is the daily schedule in csv to control system’s availability, and below is the hourly cooling results that matches the csv schedule.

Hi @MingboPeng,

I have tried the ScheduleFile to input the Source Temperature Schedule for a PlantComponent.

This error is shown:
“0. Program Version,EnergyPlus, Version 9.4.0-998c4b761e, YMD=2021.03.15 14:19,
** Severe ** [Schedule:File][Schedule File 1] - Missing required property ‘file_name’.”

Can I use the ScheduleFile to create a 8760 temperature schedule ?
Thank you,

I have the same problem when using rerun osm honeybee 1.2 but when I use legacy re-run osm 0.0.66 this was solved.

I’m also getting the same error using LBT 1.5 with OpenStudio 3.4.0 and Ironbug 1.1.1
@MingboPeng, any help is highly appreciated!

Hi all,

Please let me know if there is an issue with using CSV file as a schedule in Ironbug in the latest version with the new LBT1.7. It should be all fixed.

HI, I used the LBT 1.8.0. but I got the error, how do we create the 8760 sch for on/off of HVAC?

[behnammmohseni]

can you kindly let us know what the error is?

[miladheirani]

Thanks @behnammmohseni the error is fixed.

Can we use the 8760-hour data for COP and SEER instead of relying on a single value?
Additionally, how can we determine the outputs for cooling and heating loads?
Finally, are these loads solely based on electricity consumption?

@miladheirani

• yes you can do that, but as I see from your configuration, you took the setup static and referenced COP 4 and 3.5.
  If you look at your produced IDF, you can see that the correction factor for the temperature and the fluid flow is 1, meaning that there is no influence on the COP. They are just fixed values as you defined.

• For different Detailed HVAC, the results show the heating and cooling load is different and also it depends on what system you choose to convey the heat, whether it is by a BaseBoard, by a Radiant system, etc. You need to detect each precisely based on what you choose. I need to see your simulation to precisely tell you

• Please find the above notes, it depends on different things, one can be shown as a Heat Pump in the EUI, one as electricity, and the other as Heating or Cooling
