Upgrade ventilation for a more sustainable future
For commercial buildings with high heat gains such as schools, colleges, leisure centres, offi ces, theatres and even churches, the ideal ventilation solution to invest in is hybrid ventilation according to Breathing Buildings

espite the Government slowing down on its route to Net Zero, the UK still has the legal target to meet Net Zero by 2050. Rather than putting sustainability on the back burner to meet these targets it is important to make changes now to ensure we meet this goal. Research has revealed the building sector
accounts for 40% of global emissions. But, cutting carbon emissions is not only good for the environment it is also good for the bottom line. The current cost of utilities has hit businesses hard so investing in the latest energy effi cient ventilation can help cut fuel bills.
Hybrid
Enter hybrid ventilation, which is highly effi cient and makes use of the free heat (and so energy) that has already been built up within a space. By employing hybrid ventilation, commercial buildings can maximise health, comfort and sustainability without having to invest in signifi cant building works, making it ideal for retrofi tting. Hybrid ventilation, such as Breathing Building’s
Natural Ventilation with Heat Recycling (NVHR) range, focuses on the balance of indoor air quality (IAQ), thermal comfort, and effi ciency by choosing the most appropriate mode of ventilation based on the internal and external conditions. Supplied with an external

temperature sensor and an internal temperature and CO2 sensor as well as an intelligent controller, the latest NVHR systems monitor conditions to create an ideal indoor environment, automatically switching between natural, hybrid and mechanical ventilation, allowing the NVHR to be in the most energy effi cient mode possible at all stages, thus making it an ideal choice for commercial buildings.
For example, buildings such as leisure centres,
have an abundance of heat generated by exercising, machinery and lighting, making them ideal places to benefi t from NVHR systems. And what NVHR does perfectly, is to make use of the heat to provide excellent thermal comfort and IAQ while keeping overhead costs down, off ering energy savings and so reducing operating costs. NVHR is the ideal ventilation for commercial buildings that would like to improve their energy effi ciency and benefi t from free heat gains.
NVHRe
However, the latest innovative hybrid ventilation has now gone one stage further saving even more free heat for commercial buildings and so off ering more cost savings for businesses. The key diff erence between the original NVHR range and the new natural ventilation with heat recycling and heat recovery (NVHRe) from Breathing Buildings is the
addition of a low resistance heat exchanger cell within the unit. This allows the unit to benefi t 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 a building’s energy assessments (SBEM). By including a low resistance aluminium cross
heat exchanger to the unit, it further 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.
