The following is required to demons

The following is required to demonstrate compliance:
Up to five credits
1
An assessment of the efficiency of the building's domestic water-consuming components is undertaken using the BREEAM Wat 01 calculator.
2
The water consumption (L/person/day) for the assessed building is compared against a baseline performance and BREEAM credits awarded based upon
Table 38
.
3
The efficiency of the following 'domestic-scale' water-consuming components must be included in the assessment (where specified):
3.a
WCs
3.b
Urinals
3.c
Taps (wash hand basins and where specified kitchen taps and waste disposal unit)
3.d
Showers
3.e
Baths
3.f
Dishwashers (domestic and commercial-sized)
3.g
Washing machines (domestic and commercial or industrial sized).
The BREEAM Wat 01 calculator defines the building types and activity areas for which the above components must be assessed.
4
Where a greywater or rainwater system is specified, its yield (L/person/day) is used to offset non-potable water demand from components that would otherwise be supplied using potable water.
5
Any greywater systems must be specified and installed in compliance with the national best practice standard.
