Ventilation goes to the top of the class

Passivent has supplied a combination of Hybrid Plus2 Aircool ventilators and Hybrid Plus Airstract  roof ventilation terminals for a new London primary school to help create a healthier,  more comfortable learning environment for children and staff to thrive in.  

Greatfields Primary School in Barking and Dagenham is a three-form entry school which will eventually serve 630 pupils. This £11.8m building project was overseen by main contractor Auburn Group, who worked alongside Net Zero Buildings, the offsite construction partner. By building the structure offsite, disruption was minimised in the local area during the construction phase, helping to meet the project’s overall sustainability targets. 

Working with Cedar Mechanical and Electrical, Passivent supplied 58 Hybrid Plus2 Aircool wall ventilators, each mounted behind an external weather louvre, to ventilate the classrooms with fresh air from outside. The team also supplied several of its Hybrid Plus Airstract roof terminals for ventilation of the school’s main hall. Passivent provided temperature and CO2 sensors in each space, along with a 35-zone iC8000 controller to regulate the internal environment. The whole system was linked back to the Building Management System (BMS).  

Passivent’s Hybrid Plus2 Aircool and Hybrid Plus Airstract units both operate on three modes of use for ventilation provision or extraction, depending on the needs of the building and the external conditions. By drawing on both natural and mechanical ventilation techniques, the system is designed to be more energy efficient and therefore more cost effective. The Hybrid Plus2 Aircool units are suitable for use in classroom and can be mounted in a wall or window, and are also available as a ducted version for installation in a ceiling void. The roof-mounted Hybrid Plus Airstract terminals come with a 15-year no leak guarantee and are particularly suited for large open spaces such as school halls and sports halls. 

Marcus Bloomberg, Electrical Operation Manager at Cedar Mechanical and Electrical, says: "We were extremely impressed with the results of incorporating Passivent's natural ventilation solutions into this project. Not only does the system deliver excellent airflow and create a comfortable environment, but the unique design of the units also stands out. The softer, curved shape adds a touch of elegance and blends beautifully with the overall aesthetic, providing a refreshing alternative to the typical rectangular units.” 

Marcus went on to praise the service provided by Passivent throughout the project, having supplied and commissioned the system on time. He adds: “Ray, Passivent’s commissioning engineer, was instrumental in the project’s success. His expertise, professionalism and dedication were exceptional throughout. He went above and beyond to ensure the system was installed and functioning perfectly, and his proactive support was invaluable. We are thrilled with the outcome and highly recommend Passivent for its products and outstanding team."
