thermal modelling and working closely with the architect, and structural engineer, the solutions were integrated into the building,” says Eric Benton of Johns Slater and Haward. “I believe that the building we have delivered will work well using the lovely fresh natural Norfolk air to provide a good ventilation solution and maintain comfortable temperatures even in the middle of summer.” East Anglian Air Ambulance chief executive Matthew Jones comments: “We were unfamiliar with the concept of hybrid ventilation before this project but were able to visit the Breathing Buildings factory in Soham to see the system for ourselves
and then the Dyson Building in Cambridge which also utilises the solutions. Once the performance of the system had been demonstrated and we saw the clear benefits it provides to the workplace, we were fully behind the idea. We are looking forward to operating from the building and working in a space that is both comfortable and healthy to work in.” The Natural Ventilation with Heat Recycling (NVHR) hybrid ventilation system’s patented ultra- efficient facade-based mixing ventilation allows single-sided, enhanced natural ventilation in deep plan spaces whilst making the most of internal heat gains to deliver superb thermal comfort and

IAQ. Hybrid ventilation focuses on the vital balance of IAQ, thermal comfort and efficiency. The NVHR tackles energy efficiency and environmental issues and provides excellent indoor air quality. The energy efficient NVHR is the next generation
of energy efficient hybrid ventilation, offering almost 50% reduction in energy savings and so operating costs. NVHR comprises both natural and mechanical ventilation. Allowing low-energy hybrid natural ventilation, even in buildings with limited facade and roof space, highly efficient mixing fans mitigate cold draughts in winter and provide a ventilation boost in summer. Fitted with external and internal temperature sensors and an intelligent controller, the system monitors conditions to create an ideal indoor environment, boosting both productivity and wellbeing. NVHR optimises IAQ, comfort and efficiency by automatically switching between natural, hybrid and mechanical ventilation, maximising benefits. NVHR is suitable for use in almost any building due to its small size and can be deployed in offices, meeting rooms, schools, public areas and other deep plan spaces. NVHR has three modes: summer mode, winter mode and summer boost. In winter the heat recycling strategy for ventilation offers huge heating-bill savings while providing good ventilation. The mid-season natural ventilation mode enables the unit to maximise the benefits of passive ventilation. The summertime boost function fully opens the unit’s damper to maximise ventilation and cooler air.
