The IAQVS programme scope covers mechanical ventilation systems for single-family homes and apartments.
The categories of ventilation systems covered by the scope are the following:
The IAQVS programme is intended to certify the performance of an assembly of ventilation components forming a specific ventilation system. The performances are evaluated considering the whole assembly, which enables to assess the synergies between its constituting components.
The ventilation system is evaluated through simulations in consistency with its application field. The simulations provide performance indicators that enable to assess the ventilation system performance from both Indoor Air Quality and Energy Efficiency perspectives:
A global Indoor Air Quality indicator (IIAQ) is defined as the average of the following indicators:
Energy Efficiency indicators
The following Energy performance indicators are assessed:
They are expressed in kWh/annum (rounded to the nearest integer).
All these indicators are represented in a label specific to each ventilation system.
