Although there are three credits in Wat 03, a maximum of two credits are available, as the credits are not applicable to all buildings.
The leak detection system credit (criterion 1) is not applicable to the assessment of residential – single dwellings.
The flow control devices credit (criterion 2) is not applicable to residential assessments.
The leak isolation credit (criterion 3) is only applicable to residential assessments.
The compliance notes CN1, CN2 and CN2.1 confirm this. The criteria will be clarified in the next re-issue of the technical manual.
