Erratum – Wat 01 – Data requirements for Urinals - KBCN1878
Table 8.2 / Table 62: Data requirements for water-consuming components
incorrectly states that the data should be entered as “Flush volume in litres/bowl/hour” for all types of urinals
| Water-consuming component |
Data requirements |
| Urinals |
Flush volume in litres/bowl/hour |
These units should only apply to urinals with a timed flush. Data for urinals with automatic flush should be entered in Flush volume in litres/flush (see below)
| Water-consuming component |
Data requirements |
| Urinals with timed flush |
Flush volume in litres/bowl/hour |
| Urinals with automatic flush |
Flush volume in litres/flush |
The data entry options and units are correct in the BREEAM Platform, and the technical manuals will be updated in the next reissue.
Leak detection – compliance principle – alternative technologies - KBCN1566
Where it can be demonstrated that alternative 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 use patterns are an acceptable alternative to systems that require manual pre-sets or manual programming.
06-Jul-2026 - Title updated for consistency. Scheme applicability updated. Principle also applied to refrigerant leak detection.
Leak detection – using a BMS - KBCN0439
A BMS can be used for leak detection if it can be shown that its integrated or add-on features meet all the requirements for a leak detection system.
07-Feb-2022 - Applicability to BIU V6C confirmed.
06-Jul-2026 - Scheme applicability updated, and applied also to refrigerant leak detection across all relevant schemes.
