Aquilar - Achieving BREEAM Credits UNDERWAT3 & POL2

Leak Detection - Refrigerant Leak Detection - Water Leak Detection

Aquilar Primark


Westwood Cross Shopping Centre is a 475,000 sq.ft retail and leisure complex based in Broadstairs, Kent. Designed to be a “town centre” for the Thanet region this stunning complex attracts higher than average spenders in all key demographic groups drawing over 4.5 million visitors a year.

In Autumn 2012 Primark opened a 70,000 sq.ft showpiece store right in the heart of the development. Prior to the store opening we received an enquiry from an M&E contractor to provide solutions enabling the store to achieve BREEAM credits under WAT3 and POL2.

This involved supplying products for both refrigerant gas leak detection and major water leak detection.

On a project of this nature it is vital to understand not just the specification but also the bigger picture to ensure we met the immediate and ongoing needs of the end user client. Working closely with the M&E Contractor a full assessment was made and a product list drawn up.

The specification included:

  • The inclusion of an Aquitron AT-WM Water Monitor System to monitor water usage in line with the requirements of WAT3.
  • Refrigerant Gas Detection monitoring the stores air conditioning.
  • Commissioning and set up support to ensure correct installation and operation.

In addition to scoping and supplying the products for this project we also carried out an on-site visit to test and commission our products on behalf of the M&E contractor prior to completion.

Following an independent assessment the desired BREEAM credits were awarded for these two elements of the project.

“We were highly delighted with care and attention Aquilar gave to this project. They reacted speedily and supplied exactly what we needed to gain the necessary BREEAM credits”. Alan McSweeny – MITIE

Further project notes – products supplied

Major water leak detection, BREEAM WAT3 AT-WM water meter monitor system comprising of a programmable controller, pulsed water meter and optional solenoid valve.

  • Separate systems for installation at the site boundary and within the building
  • Programmable for different flow (leakage) rates
  • Two levels of monitoring (e.g. occupied and unoccupied building)
  • Programmable time periods to determine alarm levels

Credits available: 1
To help achieve the necessary BREEAM credit five refrigerant gas sensors were installed within the building adjacent to the air handling units within the large open plan store.

Additional sensors were installed to cover the air conditioning units in the ceiling of these three rooms:

  • Cash office
  • CCTV room
  • Admin office

The type of sensors used were: AT-G-SENSE, stand-alone 230vac sensors, providing visual and audible alarms locally with a link to the BMS (building management system).
