(4 credits available)

Aim

To reduce water consumption by encouraging the specification of water efficient showers and baths.

Question

Are the showerheads and bathtubs low water use?

Credits	Answer	Select either answer C or D, and either answer E or F
0	A	Question not answered
0	B	No
1	C	All showerheads have a maximum flow rate less than 8 litres per minute
2	D	All showerheads have a maximum flow rate less than 6 litres per minute
2	E	All bathtubs must have a maximum capacity of 170 litres
2	F	No bathtubs in place

Assessment criteria

Criterion	Assessment criteria	Applicable answer
1	Only showerheads and bathtubs within the homes need to be assessed.	B-F

Methodology

Assessor checks

An adequate proportion of showers heads and/ or bathtubs 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.
All	Photographic evidence of installed showerheads and/or bathtub
All	Manufacturer/supplier literature of water efficient specifications.
All	Where manufacturer information is not available, evidence must be provided that confirms that the showers and bathtubs meet the stated criteria. This could include; - measured flow rates of showerheads measured dimensions of bathtubs (e.g. if a bath is assumed to be a cuboid a simple Height x Depth x Width calculation will overestimate the volume of the bathtub which would be acceptable) confirmation from the manufacturer that the installed showerheads and bathtubs meet the criteria.
