Minimum standard. (1 credit available)
Aim
To ensure water consumption can be monitored and managed, and therefore encourage reductions in consumption.
Assessment criteria
The following is required to demonstrate compliance:
One credit
1 | The specification of a water meter on the mains water supply to each building; this includes instances where water is supplied via a borehole or other private source. |
3 | Each meter (main and sub) has a pulsed or other open protocol communication output to enable connection to an appropriate utility monitoring and management system, e.g. a building management system (BMS), for the monitoring of water consumption (see Relevant definitions). |
4 | If the site on which the building is located has an existing BMS, managed by the same occupier or owner (as the new building), the pulsed or digital water meters for the new building must be connected to the existing BMS (see Relevant definitions). |
Checklists and tables
None.

Applicable assessment criteria |
Both options: All criteria relevant to the building type and function apply. Criterion 2 Shell only: This criterion is not applicable Shell and core: This criterion is applicable. Refer to Appendix D – Shell and core project assessments for a more detailed description of the shell and core assessment options. |
CN1.1 |
Shell and core assessments |
Shell and core Compliance with criterion 2 must be demonstrated for water-consuming plant or building areas identifiable by the developer (see Relevant definitions). Water-consuming plant or building areas to be added or installed by the tenant do not need to be assessed for this issue. |
Residential - Partially fitted and fully fitted |

CN2 |
Applicable assessment criteria - Single dwellings |
Both options: Criterion 1 is applicable only Refer to Appendix E – Applicability of BREEAM New Construction to single and multiple dwellings, partially and fully fitted for a more detailed description of residential assessment options. |
CN2.1 |
Applicable assessment criteria - Multiple dwellings |
Both options: All criteria relevant to the building type and function apply. Refer to Appendix E – Applicability of BREEAM New Construction to single and multiple dwellings, partially and fully fitted for a more detailed description of residential assessment options. |
CN2.2 |
Utility company water monitoring equipment | Water meters installed by a water utility company that provide the future homeowner or tenant with accurate and regular water usage information per dwelling will comply with this issue. |
General | ||
Water-consuming plant or building area. See criterion 2 . |
As a minimum, this includes the following (where present):
|
|
CN3.1 |
10% of water demand. See criterion 2 . |
The sub-meter requirement does not necessarily apply in the following cases, where the assessor confirms there will be no additional monitoring benefit resulting from their installation:
|
CN3.2 |
Extensions to existing buildings. See criterion 4 . |
If no new water supply is being installed because the occupants of the extended building will use the facilities in, and therefore water supply to the existing building, then the following must be provided in the existing building:
The meters provided must have a pulsed output or connection to the existing BMS in accordance with the assessment criteria. |
CN3.3 |
No water supply to the building or unit | If there is no installed water supply to the assessed building because there will be no water-consuming fittings in the building, then in such instances the guidance given in the above compliance note for extensions to existing buildings applies. |
Methodology
None.
Evidence
Criteria | Interim design stage | Final Post-construction stage |
---|---|---|
All |
The relevant sections or clauses of the building specification or contract. Design drawings. |
BREEAM Assessor’s site inspection report and photographic evidence OR As-built drawings. |
Additional information
Relevant definitions
- Staff areas
- Refer to BREEAM issue Hea 01 Visual comfort – Relevant definitions.
- Meter outputs
- Examples include pulsed outputs and other open protocol communication outputs, such as Modbus.
- Utility monitoring and management system
- Examples include automatic meter reading systems (AMR) and building energy management systems (BEMs). Automatic monitoring and targeting (AM&T) is an example of a management tool that includes automatic meter reading and data management.
Other information
None.
