Assessment criteria

Criterion	Assessment criteria	Applicable answer
1	Filtering Where no showers are present in the asset and no showers from nearby facilities (e.g. adjacent building) will be used by the occupants and visitors, this issue can be filtered out. Also see Specific Note below.	All
2	In order to be awarded the relevant credits showers must have a maximum flow rate less than or equal to 6 litres per minute.	B-F
3	If showers have been included as a Compliant Cyclist Facility in Tra 01 Alternative modes of transport, the showers referenced must be considered within this issue even if they are not located within the asset.	B-F
4	This issue does not apply to instances where such fittings would be inappropriate for medical/health-related reasons (such instances must be justified by the design specification/the building management).	B-F

Specific notes

Asset type specific

1

Where the asset under assessment contains no water using equipment and therefore there is no water supply to the building, identify and assess the water supply to the facilities most likely to be used by the occupants and visitors to the asset under assessment. This rule also applies where the assessment consists solely of an extension to an existing building, i.e. where the extended building contains no new water using equipment because there are facilities present within the existing building.

Methodology

Assessor checks

An adequate proportion of showers within the asset need to be checked to determine whether they are low water use, although it is not necessary to check them all. At least 10% of showers within the building must be observed.

Evidence

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.
2,3	Photographic evidence of installed showers; a representative sample is sufficient.
2,3	Manufacturer/supplier literature of water efficient specifications.
2,3	Copies of asset floor plans and/or an inventory of sanitary elements demonstrating location and number of showers.
2,3	Where manufacturer information is not available, evidence must be provided that confirms that the showers meet the stated criteria. This could include measured flow rates or confirmation from the manufacturer that the installed showers meet the criteria.
