    Section 3

    3.1 System 3 – Continuous mechanical extract: centralised and de-centralised

    The information provided in Tables 5 and 6 gives guidance on good installation practice and the procedures for the inspection, air flow measurement testing and commissioning of continuous mechanical extract ventilation (MEV) systems for dwellings. The relevant design guidance is given in ADF, in particular, Table 5.2c.

    3.2 System 4 – Continuous mechanical balanced systems with heat recovery: centralised and single room

    The information provided in Tables 7 and 8 gives guidance on good installation practice and the procedures for the inspection, air flow measurement testing and commissioning of continuous mechanical balanced ventilation with heat recovery (MVHR) systems for dwellings. The relevant design guidance is given in ADF, in particular, Table 5.2d. The installation and inspection guidance is also suitable for single room heat recovery ventilators (SRHRV).
