SAV’s AirMaster Smart Mechanical Ventilation units are ensuring that good indoor air quality (IAQ) is maintained in various spaces at Albyn School in Aberdeen. Use of AirMaster units helps to ensure that the school is compliant with the latest version of Building Bulletin 101: Thermal Comfort and Indoor Air Quality – in terms of temperature and draught control and maintaining acceptable carbon dioxide (CO2) levels.
The success of the project has led to AirMaster being specified by Dundee City Council for the Balmerino Road new nursery facility.
Three AirMaster units are installed in various spaces at Albyn school. The spacious Warrack Library, for instance, is located in the original 1866 building and has large, south-facing sash and case style timber-framed windows.
The library’s ventilation needs are served by a single AirMaster AM 800 unit, mounted at high level and partially recessed into the false ceiling at 4m or so from the finished floor level. The unit is connected to the outside via 300mm vertical supply and extract ducts through the pitched roof directly above – ensuring installation was straightforward with minimal disruption to the historic building.
Other areas served by AirMaster units include the Primary French classrooms, two relatively small, south-facing spaces with no windows and a partially glazed roof. Each classroom is ventilated by an AirMaster AM 800 unit, again using vertical ductwork connections through the roof.
All of the units at the school are controlled through standalone, wall mounted AirMaster electronic touchscreen controllers, providing optimising control of local operating conditions.
Unlike hybrid ventilation units commonly used in schools, AirMaster can control CO2 levels and temperature independently of each other, avoiding draughts whilst maintaining good IAQ. They are quiet in operation and include ISO 16890 compliant filtration as standard to protect pupils from outdoor pollutants.
