Ensuring Mechanical Ventilation with Heat Recovery Systems Are Quiet

Mechanical ventilation with heat recovery (MVHR) systems, provide a controllable method of ventilating dwellings while delivering energy savings. They are particularly useful for ventilating homes in noisy areas or high-rise buildings where open windows are not workable. However, they can be a source of noise, particularly if they are not located and installed carefully. Drawing on a range of large residential projects, laboratory testing and on-site measurements, this session will present the acoustic advantages and pitfalls with their use, and will give real advice to engineers, architects and contractors on how to specify and configure these systems for quiet operation.
