AirMaster Case Story Queensferry High School

The Scottish climate provides school designers with a challenge: to provide good indoor air quality whilst maintaining thermal comfort and good acoustic design.

As such, BB101 (Guidelines on ventilation, thermal comfort and indoor air quality in schools) needed to be applied. Concerned about the risk of draught, the

mechanical consultant Ramboll, undertook a computation fluid dynamics (CFD) study. The CFD found that a mechanical ventilation with heat recovery was the

only solution able to meet all criteria, whilst managing low external temperatures.

Results of the CFD in hand, Ramboll, Glasgow selected 1 x AM 300, 3 x AM 500 and 38 x AM 800 units for the project. AirMaster MVHRs can supply tempered fresh air from outside at external temperatures below minus 5°C, having been designed for Nordic climates, with supply temperatures of 17°C plus, without causing draughts. By supplying fresh air only to these classrooms, without recirculation of stale air, the goal of maintaining a CO2 level of less than 1,000 ppm can easily be met.
