Breeam (Building Research Establishment Environmental Assessment Method), first published by the Building Research Establishment (BRE) in 1990, is the world’s longest established method of assessing, rating and certifying the sustainability of buildings.
This points-based certification is managed by Breeam assessors who work out the exact point allocation per building. Each category listed within the guidance qualify for points. For example, 8.0 is Water, can achieve up to 9 credits within the following sections:
- Wat 01 Water consumption
- Wat 02 Water monitoring
- Wat 03 Water leak detection
- Wat 04 Water-efficient equipment
And within these categories credits can be achieved by the use of products such as:
- WCs with Effective flush volumes from 4.5 to 3 litres
- Wash-hand basin taps with flow rates from 8 to 3 litres/min
- Showers with flow rates from 10 to 3.5 litres/min
- Urinals (2 or more urinals) from 6 to 0 litres/bowl/hour
- Urinals (1 urinal only) from 8 to 0 litres/bowl/hour
- Greywater and rainwater systems where 0% to 75% of WC or urinal flushing demand is met using recycled non-potable water
KWC DVS BREEAM Compliance
Aquarius automatic taps supplied by KWC DVS Ltd are fitted with a 5L/min pressure compensating flow regulator that ensures the water flow is limited to 5L/min. The flow rate satisfies the BREAAM requirement of 6L/min.
KWC DVS Ltd individual urinal control systems consist of a presence sensor connected to an electronic control system that opens and closes a solenoid valve to control the volume of water used to flush the urinal. This satisfies the BREAAM requirement of urinals fitted with individual presence detectors that operate the flushing control after each use.
The control system incorporates dip switches than can be set for various times allowing the volume of water to be controlled and set to <1.5 l/flush which is a requirement of the water regulations.
The WC Flushvalve supplied by KWC DVS Ltd can be adjusted to control the volume of water used to flush a WC. The flush volume can be set by adjusting the valve open time using dip switches in the WC00-010 control box, the dip switches or programmable input of the WC00-009 control box, the front panel menu system of the VR07-002 control box and also the programmable input of the VR07-020 multi-channel washroom control box. The flush volume can thereby be set to 4.5 litres satisfying the BREEAM requirement that all WCs have an effective flush volume of 4.5 litres or less.
