Breathing Buildings’ NVHR Wins at HVR Awards

Breathing Buildings, the provider of controlled hybrid ventilation systems, is celebrating winning ‘Commercial/Industrial Ventilation Product of the Year’ category at the HVR Awards 2018. The Cambridge-based company’s new energy efficient NVHR (Natural Ventilation with Heat Recycling) scooped the award at a glittering awards ceremony on Thursday, October 25 at London’s Chelsea Harbour Hotel.

With a wave of innovative products being launched in response to changing legislation and regulation, this year’s product categories were more hotly-contested than ever. Ultimately it was Breathing Buildings that came out on top, winning the Commercial/Industrial Ventilation Product of the Year award for NVHR – which according to the judges, stood out in a high-quality category for its technical features, ability to tackle energy efficiency and environmental issues and to provide excellent indoor air quality in schools and other facilities.

“We are delighted our NVHR system has been acknowledged at the HVR Awards,” said Matthew Bray, commercial director at Breathing Buildings. “At Breathing Buildings, we are committed to designing solutions to create efficient, healthy and comfortable environments in schools that enable children to benefit from effective teaching and learning spaces. The new BB101 2018 guidance sets more stringent air quality targets, is tougher on summertime overheating, and recommends pre-mixing of incoming air to eliminate cold draughts, all of which are achieved by our new NVHR. We are therefore thrilled to have gained industry recognition.”

Recognising the vital importance of good indoor air quality (IAQ) and thermal comfort, the new NVHR from Breathing Buildings is designed specifically to meet the robust ventilation criteria set out for schools. Its 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 indoor air quality. Its award win is therefore particularly timely since it comes shortly after the launch of the new 2018 edition of BB101: Guidelines on ventilation, thermal comfort and indoor air quality in schools. The 2018 BB101 has added hybrid ventilation as a design solution for schools and focuses on the vital balance of indoor air quality, thermal comfort and efficiency.

Breathing Buildings’ new NVHR is the next generation of energy efficient hybrid ventilation, offering almost 50% reduction in energy savings and so operating costs. Boasting the highest energy efficiency and air flow within the acoustic limits required for its school application, NVHR comprises both natural and mechanical ventilation. Allowing low-energy hybrid natural ventilation, even in buildings with limited façade 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 indoor air quality, comfort and efficiency by automatically switching between natural, hybrid and mechanical ventilation, maximising benefits.
