Buildings.Controls.OBC.ASHRAE.G36.ZoneGroups.Validation

Collection of validation models

Information

This package contains validation models for the classes in Buildings.Controls.OBC.ASHRAE.G36.ZoneGroups.

Note that most validation models contain simple input data which may not be realistic, but for which the correct output can be obtained through an analytic solution. The examples plot various outputs, which have been verified against these solutions. These model outputs are stored as reference data and used for continuous validation whenever models in the library change.

Validate block for checking temperatures in the group

Buildings.Controls.OBC.ASHRAE.G36.ZoneGroups.Validation.GroupStatus

Information

This example validates Buildings.Controls.OBC.ASHRAE.G36.ZoneGroups.GroupStatus for checking group temperature status.

The block takes 3 zones as input, but filters them down to only processing zone 1 and 3 (reindexed in output to 1 and 2 respectively).
