Retail

Cistermiser products can help gain BREEAM points within the water section of the BREEAM buildings assessment for retail developments:

  Cistermiser Easyflush

  Cistermiser Directflush

  Cistermiser Novatap

  Cistermiser AV Range

Credit ref: W01
Up to three credits are awarded where evidence provided demonstrates that sanitary facilities are designed to minimise the consumption of potable water as follows:

One credit
Where all WCs have a dual flush cistern with a six litre main flushing capacity and reduced flush volume of four litres. Plus instructions on the appropriate operation of the flushing device provided on the cistern, or nearby for a group of cisterns.

OR
Two credits
Where all WCs have a dual flush cistern with four litre main flushing capacity and reduced flushing capacity of two litres, or where all WC's have a vacuum flush system or they are waterless plus instructions on the appropriate operation of the flushing device.

And
One credit
Where, of the following, the two that offer the greatest possible reduction in water consumption have been specified;

1. All taps are one, or a combination of, the following types; timed turn off push taps, electronic sensor taps, spray taps, aerating taps.
2. All showers, where specified, have a nominal flow rate the same as or less than 9 litres per minute at 1.5 bar pressure.
3. All urinals are either: infra-red proximity detection with controls on each individual urinal (so the urinal only flushes after its use) or waterless.

The Cistermiser Easyflush no touch dual flush WC valve has a standard 6l flush with an adjustable part flush. The full flush can also be adjusted by means of the float position to provide a maximum flush volume of 4l with a subsequent reduction in part flush. The Easyflush unit is also unique in providing a linked flush and fill function ensuring that during the flush cycle the inlet valve cannot open ensuring no additional water can pass out of the open cistern outlet. As the Cistermiser Easyflush is also touch free it has significant advantages with regard to infection control and some significant anti vandal and maintenance benefits.

The Cistermiser Direct Flush (Discreet and Accessible) urinal control valve achieves the necessary credit rating by providing infra red activated flush control to each urinal individually from the mains water supply. The flush is reduced to approximately 0.5 litres per operation and also has a flush arrest function to reduce water consumption further during periods of high use. The unit is programmable for flush duration, sensing range and has a hygiene rinse function for periods of low occupancy thereby maintaining a good environment within the washroom. Cistermiser DF products also have a cleaner's function which will reduce water consumption further during essential maintenance.

The Cistermiser Novatap hands free infra red basin spout achieves the necessary credit rating by providing infra red activated control to give a regulated flow of 5 litres per minute across a pressure range of 0.5 - 6 bar by means of a dynamic pressure compensated flow regulator within the spout outlet. The Novatap can also reduce water consumption by means of a programmable run on that can drastically reduce the amount of time taps are allowed to run during and after use. Novatap is also extremely hygienic as it is a touch free infrared operated unit. Cistermiser Novatap can also help achieve further BREEAM credits under credit reference HW16 where hot and cold water systems have been designed, or actions taken to minimize risks of microbial contamination. This is in accordance with the guidelines in HSE ACoP L8.

The Novatap can provide credits in this category when it is being used on hot water systems in conjunction with Thermostatic Mixing Valves as the Novatap has a periodic hygiene rinse function that prevents the warm, mixed water from stagnating in the supply line between the TMV and the outlet thereby reducing the risk of microbial contamination such as legionella.

The Cistermiser AV Range can provide credit ratings for W01 above by means of providing control to WCs by means of an electronic touch button control to provide a dual flush, the system can also be used to flush the urinals in conjunction with the Direct Flush valve and can also be used to provide basin outlets that are electronically touch contolled. A further advantage of AV range is that it can provide a shower function that is flow regulated to give 7l/min at 1.5bar pressure.

The Cistermiser AV Range can also provide credits in the HW16 category when it is being used on hot water systems in conjunction with Thermostatic Mixing Valves as the AV Range has a periodic hygiene rinse function that prevents the warm, mixed water from stagnating in the supply line between the TMV and the outlet thereby reducing the risk of microbial contamination such as legionella in showers and basin outlets. This is in accordance with the guidelines in HSE ACoP L8.
