Natural Ventilation with Heat Recycling

NVHR is the newest product from Breathing Buildings as we continue to change the way the building industry thinks about Natural Ventilation.

The NVHR 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 facade and roof space to be naturally ventilated. Its low-energy mixing fans mitigate cold draughts in winter and provide a supply air boost in summer. The system is fitted with external and internal temperature sensors and an intelligent controller, which monitors conditions to create an ideal working environment.

The system can be deployed in almost any building due to its small size.
