Flow control devices – Use of devices on individual sanitary fittings - KBCN1550

The intent of the requirement for flow control devices is to minimise the impact of undetected wastage and leaks from sanitary fittings and supply pipework. The use of flow control devices on individual sanitary fittings alone does not, therefore, fully meet this aim.

Leak detection technologies – Compliance Principle - KBCN1566

Where it can be demonstrated that alternative water leak detection technologies can meet or exceed the capabilities of systems set out in the BREEAM guidance, subject to approval, these can also be considered compliant. It is the role of the Assessor and the project team to provide evidence and justification in a compliance principle query (see KBCN1555). The following alternative solutions are currently recognised:

• Smart leak detection systems that are based on 'self-learning' (machine learning) to determine normal water use patterns are an acceptable alternative to systems that require manual pre-sets or manual programming.
