BREEAM Major Water Leak Detection

Wat 03 Water leak detection and Prevention
No. Credits available: 1

The AquiTron AT-WM is a pulse water meter, leak monitoring system that has been specifically designed to help achieve the requirements of 2018: 1.0 BREEAM UK New construction (non-domestic buildings).

The AT-WM system will allow designers, M&E contractors and developers to achieve the “Credit” available to reduce the impact of water leaks that may otherwise go undetected.

All the leak detection water meters and solenoid valves are WRAS-approved.

The system is designed to monitor water flowing through a pulse water meter. If the volume of water reaches the pre-set limit (customer adjustable) the system can isolate the mains water pipe, therefore limiting the amount of water and leak damage.

AT-WM System: meets BREEAM wat03 criteria

The leak detection system is:

1. A permanent automated water leak detection system that alerts the building occupants to the leak OR an inbuilt automated diagnostic procedure for detecting leaks
2. Activated when the flow of water passing through the water meter or data logger is at a flow rate above a pre-set maximum for a pre-set period of time. This usually involves installing a system which detects higher than normal flow rates at meters or sub-meters. It does not necessarily require a system that directly detects water leakage along part or the whole length of the water supply system
3. Able to identify different flow and, therefore, leakage rates, eg continuous, high or low level, over set time periods. Although high and low level leakage rates are not specified, the leak detection equipment installed must have the flexibility to distinguish between different flow rates to enable it to be programmed to suit the building type and owner’s or occupier’s usage patterns
4. Programmable to suit the owner’s or occupier’s water consumption criteria
5. Where applicable, designed to avoid false alarms caused by normal operation of large water-consuming plant such as chillers

BREEAM PIR Automatic WC Water Shut-Off System

Wat 03 Water leak prevention system
No. Credits available: 1

The Aquitron AT-PIR-SOV is a controller, PIR sensor and water solenoid valve system used to isolate the water supply to WC’s when they are not in use, thereby limiting the risk of water wastage and damage from minor water leaks. Both the brass and polyamide leak detection solenoid valves are WRAS-approved.

One credit – flow control devices:
Install flow control devices that regulate the water supply to each WC area or sanitary facility according to demand, in order to minimise undetected wastage and leaks from sanitary fittings and supply pipework.

The system comprises a main controller, ceiling mounted recessed or surface mounted PIR sensor and either a 15mm, 22mm, 28mm or 35mm solenoid valve. Up to 3 valves can be powered by the controller.

If no movement is detected within the user adjustable pre-selected time, the PIR sensor will activate the isolating solenoid valve.

• Automatic water shut-off when WC area/facility is not in use
• Reduces the risk of flooding due to accidental damage or vandalism
• Avoids water wastage if taps left running
• Ceiling or wall mounted PIR detects the presence of a person entering the area and opens the solenoid valves
• Male/female toilets with a shared water feed can be controlled with a master and slave PIR unit, allowing either area to be occupied and therefore operating the solenoid valves.
• Each solenoid valve is powered from the Master PIR controller using 6v dc valves.
• Auxiliary relay contacts are available to isolate mains and/or lighting supply in the same room.

BREEAM Refrigerant Gas Leak Detection

Pol 01 Impact of Refrigerant
No. Credits available: 1

A BREEAM credit may be achieved by installing an AquiTron refrigerant gas leak detection system within your building.

The AquiTron range of refrigerant gas leak detection systems has been designed to help achieve the requirements of BREEAM 2011 (BRE Environmental Assessment Method).

To conform to BREEAM 2018.01 requirements, the AquiTron AT-G-ALERT and AT-RLM2 permanently installed multi-point refrigerant leak detection systems utilise infra-red, semi-conductor or electro-chemical type of sensors to continuously monitor the atmosphere in the vicinity of refrigeration equipment.

The systems have been used on many completed BREEAM projects and achieved the credit. Most commonly associated with detection within building’s chiller plant rooms, offices, computer rooms and the base of refrigerant pipework risers, plus any internal air conditioned areas.

Can also be successfully used for external condensers and plant when sensors are installed within the compressor housing on chillers, air handling equipment or condensing units.

System features:

• Single and multi-point sensors
• Sensor suitable for positioning at low level within the occupied space
• Sensor technologies used ‘semi-conductor, infra-red, aspirated’ are all on the approved BREEAM 2018; 01 listing
