Breathing Buildings’ new units set standard for more sustainable future

Breathing Buildings introduces the new NVHRe to its award-winning range of Natural Ventilation with Heat Recycling (NVHR®) systems, raising the bar on energy efficient ventilation.

The key difference between the original NVHR® range and the new Natural Ventilation with Heat Recycling and Heat Recovery (NVHRe) is an addition of a low resistance heat exchanger cell within the unit.

This allows the unit to benefit from both heat recycling and heat recovery, reclaiming even more heat than previous models, saving more energy, providing great occupant comfort, and allowing users to include it within the building energy assessments (SBEM).

Boasting the lowest energy consumption for a hybrid heat recovery ventilation unit in the industry, the NVHRe combines 46% heat recovery efficiency with low Specific Fan Power (SFP) of 0.093 W/l/s to help maximise a building’s energy savings. In addition, the NVHRe has several different operating modes to minimise energy use, enhance indoor air quality (IAQ) and improve occupant comfort.

Intelligent

An intelligent hybrid system, the unit automatically decides when and if mechanical operation is required, ensuring it only operates when absolutely necessary.

Providing excellent thermal comfort and enhanced IAQ, the NVHRe is designed to suit a diverse range of commercial and public buildings with high heat gains, such as schools, colleges, leisure centres, offices, theatres and even churches. The inclusion of the low resistant aluminium cross plate heat exchanger to the unit lowers energy costs by reducing the reliance on space heating to maintain thermal comfort in a room.

It operates during colder external temperatures, typically below 7ºC when mixing recycled air alone is not enough to maintain the desired temperature for occupants. 

The range also includes units that can be the primary source of heat; needing no radiators, as well as a system that can offer further cooling. The British designed and manufactured units come in three models with product variations to suit every need with the standard NVHRe 1100 an NVHRe+ 1100 which includes a heating coil and is ideal for buildings in cooler areas; and an NVHRe C+ 1100 which features both heating and cooling coils for year-round comfort and full temperature control.

‘The next step’

Louise McHugh, Product Manager at Breathing Buildings, says: “The NVHRe marks the next step in hybrid technology. Offering an industry-leading ventilation product for schools, which boasts the lowest energy consumption, Breathing Buildings’ NVHRe delivers 46% heat recovery efficiency with extremely low SFP levels to help building owners achieve their sustainability targets on the journey to Net Zero Carbon.

“With energy costs high, building owners are increasingly looking for energy efficient ventilation solutions, the NVHRe offers this plus its heat recovery reduces the amount of energy used for heating.”

Breathing Buildings’ multi-award-winning natural ventilation with heat recycling (NVHR®) range won the Energy Efficient Product of the Year Award at the prestigious Energy Awards, and also recently won three awards for providing ventilation to the East Anglian Air Ambulance project with the Breathing Buildings’ NVHR® range.
