Aim

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 all that apply
0	A	Question not answered
0	B	Not metered
1	C	Site – where water consumption is metered for the whole site
1	D	Building – where water consumption is metered at the whole building level
1	E	Home – where water consumption is metered at the home level

Criterion	Assessment criteria	Applicable answer
1	A water meter is installed and only measures the relevant water supply.	C,D
2	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.	C,D
3	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: Utility supply Rainwater harvesting Greywater harvesting Blackwater harvesting	C

Criteria	Evidence requirement
-	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.

Blackwater:

Wastewater that has been discharged from kitchen and utility sinks, urinals and toilets within the asset.
