Parameterisation & usage

In these blocks a file can be inserted, which will give the values in the column. Note that the time column unit needs to correspond with the used unit in the file.

The desired values needs to be filled in a .csv-file. The amount of columns can be up to 4 for the small one, and up to 20 for the large BC. The primary column will be a time column, which needs to correspond to the set unit.

If you have yearly data, note that the “time is relative to simulation start time” should be set to “No”.

Examples:

In the example below, a large file is made to show when there is demand in the building on a daily basis.

As seen here, on day 2, 4 and 6 a “1” is given to indicate demand in the building.

Key points for the .csv file format

  • The first column in the .csv file is the time column

    • The time column can only carry unique values

    • The values in the time column do not need to be consecutive

    • The time column can have non-uniform timesteps.

    • The time column does not need to be sorted. Hysopt will do sorting at the start of the simulation.

    • All cells between the top time value and bottom time value need to be filled in and thus cannot remain empty.

  • The datafile matrix cannot contain any empty cells. For each variable, every timestep requires a value.

  • Ensure that non-existing columns are effectively empty. Verify this by opening the .csv with e.g. Notepad
