To get started with NVHR, you will need to import the units into your building model. The units are represented in the VE by components – when placed into a room, the room will automatically be updated to make use of the NVHR unit. You can import the units by clicking on the Import the required NVHR® systems from library item in the navigator – this will open the Add Components From Library window with the Breathing Buildings NVHR® library pre-selected:
There are currently two types of unit that you can import into the VE – ducted or un-ducted. Details on selecting which type of unit would be best suited for your usage are given in NVHR Background or should be discussed with Breathing Buildings (see Appendix B: for contact details). You can review the overview of each unit by clicking on it – this will also allow you to download the product datasheet.
To import the units, click on the checkbox next to the type(s) you want, then click on the Import Checked Components button. This will then copy the relevant component(s) into your model’s component library, making them ready to be assigned to rooms. In addition to the unit(s) themselves, the first import of an NVHR unit to the model will also import some typical ancillary data that can be used when setting up your default room openings (louvres and windows) prior to assignment:
· Typical MacroFlo opening types for louvres and windows
· Typical CDB constructions for louvres
Note: If you do not require these items, they can be manually removed from your model after import using standard CDB and MacroFlo functionality if you have not already assigned them to openings in the model .
Once the units have been imported, you can close the Add Components From Library window by clicking on the Close button.
