Hi everyone I am trying to create a cooling set point schedule in CSV format but I can't figure out how the dual point schedules are put together.

My schedules works fine with Occupancy, Activity, Lighting, Equipment, Infiltration, but for Cooling and Heating EP rejects my schedules. I am using the Honeybee/Ladybug interface in Grasshopper for EP.

Could anyone provide me with an example CSV-schedule for cooling set points?
(yearly, but actual set points does not matter)

This is how my current csv file is constructed:

Honeybee Schedule file (to be used in combination with a thermal simulation program), , , Continuous, Temperature
Schedule file address:c:\SomeNameForACoolingSetp.csv; SomeNameForACoolingSetp.csv: This is a custom schedule created by the user.,,,Occupied Hours: N/A
1,,,,Values [units],N/A
month, day, hour, values
0, 1, 0.5, ,50.0
0, 1, 1.5, ,50.0
0, 1, 2.5, ,50.0
...
11, 31, 21.5, ,50.0
11, 31, 22.5, ,50.0
11, 31, 23.5, ,50.0

Best regards

It looks like "values" are coming out in column 5, and column 4 is empty. We would also need to see the corresponding IDF object Schedule:File.

There is nothing special about a cooling setpoint schedule vs any other schedule. It is just a matter of setting the Schedule:File object to grab the correct column of data beginning at the correct row. Note that the same schedule file can have multiple columns of data representing different schedules. If you are having trouble with the file generated by Honeybee/Ladybug (or any other interface, for that matter), I would suggest exporting or copying the raw files out to a side folder and run with EP-Launch so you can troubleshoot. It is also helpful to use Output:Variable,*,Schedule Value to report out the schedules to be sure you are getting the numbers you expect, especially when using an automated workflow. As @Archmage noted, it appears that your values do not align with your column headings.

Hi Michael and Archmage

Thank you for answering. I tried troubleshooting with EP-launch but couldn't figure out what was wrong. The file shown above acted as it supposed to but not when launching it with Honebee. Today Mustapha found it to be a bug in Honeybee. Problem solved

Thanks for all the help.
