Technical Details

NVHR
The NVHR system allows single-sided, natural ventilation in deep plan spaces whilst making the most of internal heat gains to deliver optimum thermal comfort. This system allows buildings with limited facade and roof space to be naturally ventilated. Its low energy mixing fans mitigate cold draughts in winter and provide an exhaust boost in summer.

Performance Component
The ability to model the Breathing Buildings NVHR system in the Virtual Environment is available as part of the VE 2017 release.

The NVHR performance component has been added to the library of predefined 3D component representations of manufacturers systems that can be easily dragged from a catalogue of products onto a building model constructed within the IESVE. Performance and energy savings can then be assessed in an open and transparent process so that users can be confident in the performance of their chosen systems.

NVHR Navigator
Once the geometry of the model has been set up in the Virtual Environment, the steps involved in integrated the NVHR component are automated via the Navigator.

The NVHR Navigator has several key features including:

•    In-model checks and model warnings to help users ensure the system is set up correctly
•    In-model colour coding to show that the model is correctly set up in preparation for simulation
•    Guidance for Part L2 (UK) and provides automated CIBSE TM52 reportage
