Fire hydrants and sprinklers - KBCN0680

Where it is confirmed by an appropriate project team member that it is not possible to fully meet the leak detection criteria for fire hydrants or sprinklers, an alternative approach can be implemented for these systems. This must demonstrably meet the aim of the issue by detecting and alerting the building management to major water leaks.   Previous guidance - superseded on 30 May 2024 To meet BREEAM compliance, emergency systems such as fire hydrants and sprinklers need also to be covered by a leak detection system. The leak detection system must cover all mains water supply between and within the building and the ‘site boundary'.
30 May 2024 - New guidance introduced to clarify that BREEAM compliance should not compromise the operation of building safety-critical systems. Applicability to NC V6 standards confirmed.

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:

Sanitary fittings used in religious practices – updated - KBCN1624

Such fittings should not be included in the scope of this Issue. Please refer also to KBCN0418 This guidance relates to fittings and facilities used in some religious practices, for example, for washing before prayer.
03 Nov 2023 - Updated. Previous guidance was incorrect and contradicted the approach outlined in KBCN0418

Shower with multiple shower heads - KBCN0855

To calculate the water use of a shower with more than one shower head, one of the following should be done:
22 Feb 2024 - Applied to BIU, BREEAM NC and RFO standards

Using water from natural underground sources to offset water consumption - KBCN00094

Water from natural underground sources (for instance aquifer water accessed via boreholes) cannot be used to offset: A significant amount of water used for public consumption is already drawn from aquifers. Private boreholes may be drawing water from the same sources as public utility companies.
27-Mar-2024 - Title and text updated to broaden definition. Scheme applicability updated.

Washing machines and dishwashers – Water consumption data - KBCN1571

The water consumption data used to demonstrate compliance may be based on the lowest full wash cycle (i.e. not a pre-wash cycle, for example).
