Natural Ventilation with Heat Recycling (NVHR®) is the latest natural ventilation product from Breathing Buildings Ltd. Natural ventilation is an important consideration for all new buildings. Good air circulation ensures that occupants are comfortable and it is required as part of the Building Regulations Part F. Additionally, with the environment, cost of energy and long term maintenance all being areas of concern, any system should provide energy-efficient long term ventilation.
NVHR is the latest product from Breathing Buildings that is changing the way the industry thinks about Natural Ventilation. The patented mixing ventilation system allows single-sided, natural ventilation in deep plan spaces whilst making the most of internal heat gains to deliver superb thermal comfort. This system allows buildings with limited façade and roof space to be naturally ventilated. Its low energy mixing fans mitigate cold draughts in winter and provide boost in summer. The system is fitted with external and internal temperature sensors that enable the system to create an ideal working environment.
The units are designed primarily for offices and school classrooms and can be deployed in almost any building due to their small size. They can work individually or as multiples (typically a pair for a standard school classroom), directing air to the back of the space to provide a quasi-cross-flow system. It is designed to meet the Department for Education “Guidance on ventilation, thermal comfort and indoor air quality in schools” and the Facilities Output Specification (FOS) for the Priority Schools Building Programme (PSBP). The units can be used with a grille or ducted arrangement to supply air.
Further details on the units, air flow strategies and technical data is provided in this user guide (see NVHR Background). For the latest details on the NVHR product or to discuss potential suitability for your project, please visit http://www.breathingbuildings.com.
Requirements for using NVHR in the Virtual Environment
The Virtual Environment (VE) software includes built-in support for simulating both ducted and ductless NVHR units from Breathing Buildings. However, in order to simulate you will need valid licenses for the following VE modules:
· ModelIT
· Apache
· MacroFlo
· SunCast
· ApacheSim
If you are missing one or more of these licenses, you will not be able to use the Breathing Buildings functionality within the VE. Please contact keys@iesve.com for queries or support with licensing issues.
