Appendix A: Frequently Asked Questions

Q: Why are some actions on the Breathing Buildings NVHR® navigator greyed out?

A: If the action is greyed out but also has a small padlock icon shown on its checkbox ( ), this indicates that you do not have a suitable view licence to carry out that action. See Requirements for using NVHR in the Virtual Environment for more details on the licences required to use the NVHR integration within the VE.

If the padlock is not displayed but the action remains greyed out, this means the action requires you to tick one or more previous actions (therefore acknowledging that you have performed them) before you can carry out the action.

Q: I have a number of rooms contained in one NVHR unit group. I want one of these rooms to use slightly different NVHR properties (e.g. heating set-point) to the others – how can I do this?

A: All rooms assigned to an NVHR unit group will share the same NVHR properties. If you want one or more of the rooms to use tweaked values, you must create a duplicate of the unit group, tweak the relevant values in that duplicate group, then re-assign the appropriate rooms to that duplicate group instead. See Duplicating Unit Groups for guidance on how to achieve this.

Q: Can I have different NVHR units within the one room (e.g. a ducted unit and a ductless unit)?

A: This is not currently possible – for modelling within the VE, a room can only be assigned to a single NVHR unit group (and therefore a single unit type).

Q: Do I need to use the Breathing Buildings NVHR® navigator workflow to apply NVHR to my model, or can I do it myself?

A: The navigator acts as a guide to best-practice and offers the most straightforward workflow for applying NVHR to your model. However, you can import NVHR components from the source library, assign rooms to the unit groups and so on without using the navigator. It is recommended that you follow the navigator for convenience and practicality, unless you have a specific situation where you need to do otherwise.
