To reduce the consumption of water in buildings through the effective management and monitoring of water consumption.
To what level is water consumption metered?
|Credits||Answer||Select a single answer|
|0||A||Question not answered|
|2||C||Site – where water consumption is metered for the whole site|
|4||D||Building – where water consumption is metered at the whole building level|
All water-consuming plant or building areas that consume 10% or more of the building’s total water demand are either fitted with sub-meters or have water monitoring equipment integral to the plant or area
Where the building is multi tenanted: water consumption is metered per tenanted area
|Exemplary||F||All the requirements for answer option E are met, but sub-meters also have a pulsed output connected to a Building Management System (BMS)|
|Criterion||Assessment criteria||Applicable answer|
|1||A water meter on the utility-supplied water to the site or building (whichever is applicable) including where water is supplied via a borehole or other private source.||C,D|
|2||Evidence provided demonstrates that a water meter is installed on relevant water supplies to the specific response given in the credit criteria.||C-E|
Each water meter has the ability to have instantaneous reading (e.g. has a pulsed output) and enables connection to a Building Management System (BMS) for the monitoring of water consumption.
Note: water meters do not necessarily have to be connected to a BMS, as long as they have the ability to be connected to a BMS at a later time.
Where water is metered and monitored at site level, the water meters must measure all water that is utilised on-site, including, but not limited to:
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:
|-||The evidence below is not exhaustive, please also refer to the ‘BREEAM evidential requirements’ section in the scope of the Guidance for appropriate evidence types which can be used to demonstrate compliance.|
|All||Copies of site/building/asset plans, indicating where water meters are located.|
|All||Photographic evidence of installed water meters.|
|All||Copy of most current water meter readings to confirm that all meters are working.|
|3||Product manufacture details of the meter(s) installed or BMS screen shots confirming how the meters enables connection to a Building Management System.|
Water that has been discharged from kitchens, baths or showers, laundry rooms and similar within the asset.
Water that has been provided by an organisation that supplies a public service under regulation by the Government (e.g. mains water)
