Breathing Buildings’ Pioneering Hybrid Ventilation Shortlisted in Prestigious HVR Awards

Breathing Buildings’ Pioneering Hybrid Ventilation Shortlisted in Prestigious HVR Awards

Breathing Buildings, a leading provider of controlled natural and hybrid ventilation systems, has reached the final of the prestigious HVR Awards.

The company is celebrating its NVHR® 1700, Breathing Buildings’ latest energy efficient hybrid ventilation unit, being shortlisted within the Commercial/Industrial Ventilation Product of the Year category. The HVR Awards recognises and rewards companies that demonstrate excellence in their field and true innovation in the way that they operate or in what they produce. The winners will be announced at a glittering awards ceremony on 5 October at The Chelsea Harbour Hotel, London.

Breathing Buildings’ NVHR® 1700 is an exciting addition to the company’s multi-award-winning natural ventilation with heat recycling (NVHR®) range. Not only has the NVHR® range won the Energy Efficient Product of the Year Award at the prestigious Energy Awards, but it also recently won three awards for providing ventilation to the East Anglian Air Ambulance project that utilised Breathing Building’s NVHR® range.

The new NVHR® 1700 is a larger unit which is ideal for leisure centres, halls, sport facilities, shopping centres, offices, schools, and other buildings with high heat gains, with the NVHR® 1700 offering excellent ventilation and thermal comfort. Meanwhile, in school classroom applications the NVHR® 1700 now allows one unit to be specified rather than two, which means a simpler and quicker installation.

The NVHR® 1700 offers enhanced natural ventilation with hybrid technology in a slimline, compact, lightweight and energy efficient unit. The unit is designed to fulfil the ventilation needs automatically with its demand-controlled equipment, best-in-class flowrate, low noise levels and low energy consumption. The NVHR® 1700 leads the way in efficiency with specific fan power levels as low as 0.08 W/l/s and in larger applications provides airflow rates as high as 540l/s.

“At Breathing Buildings, we are committed to designing solutions to create energy efficient, healthy and comfortable environments and so we are thrilled the NVHR® 1700 is shortlisted in the prestigious HVR Awards. Our new NVHR® 1700 provides ultra-low energy, natural ventilation with hybrid technology, offering energy savings and so reducing operating costs. The NVHR® 1700 is the ideal ventilation solution for your rooms, making use of free heat gains to provide superb air quality and excellent thermal comfort without the upfront cost and future maintenance bills – essential in an energy and cost of living crisis,” said Louise McHugh, Product Manager at Breathing Buildings.

The NVHR® 1700 also boasts other additional benefits beyond Breathing Building’s current NVHR® range of products, since one single unit can be used to ventilate a room or space rather than two smaller units. As a result, when installing the NVHR® 1700 only one penetration through the external façade is needed rather than two and only one external weather louvre is required. Plus, since there is only one unit to wire to less cabling is required during installation and only one power supply and one fuse spur are needed. All these benefits save time and so costs when it comes to installation. In addition, the NVHR® 1700 also features an upgraded user interface which makes it easier for occupants to control the ventilation and so achieve the indoor air quality and comfort required.

Breathing Buildings’ Pioneering Hybrid Ventilation Shortlisted in Prestigious HVR Awards

The NVHR® hybrid ventilation system’s ultra-efficient facade-based mixing ventilation allows single-sided, enhanced natural and hybrid ventilation in deep plan spaces whilst making the most of internal heat gains to deliver superb thermal comfort and indoor air quality. Hybrid ventilation focuses on the vital balance of indoor air quality, thermal comfort, and efficiency by choosing the most appropriate mode of ventilation based on the internal and external conditions, allowing the NVHR® to be in the most energy efficient mode possible at all stages. This range of products tackles future environmental issues while providing excellent indoor air quality.

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. Supplied with an external temperature sensor, and an internal temperature and CO2 sensor, as well as an intelligent controller the system monitors conditions to create an ideal indoor environment, boosting both productivity and wellbeing.

In addition, the NVHR® benefits from Secure Night Cool mode which during the summer months provides natural ventilation at night to purge excess heat and reduce the internal temperature to 18 degrees C to help ensure a comfortable indoor temperature at the start of the day.

Featuring easy-to-use controls with manual override NVHR® allows buildings without a Building Management System (BMS) to benefit from the technology while also offering full BMS integration. Furthermore, the NVHR® 1700 has ultra-easy app-based commissioning for a faster, safer, and more accurate installation

Designed to meet thermal comfort and air quality criteria of: BB101 (2018); PSBP FOS; ESFA Annex 2F and CIBSE TM52. The Breathing Buildings NVHR® also offers quiet operation and is fully compliant for classrooms, science laboratories and offices. Countless schools and colleges nationwide benefit from Breathing Buildings ventilation units, many of which feature on the company’s website. In addition, the NVHR® is CE certified.
