Up to 7 credits for reducing water usage per person per day compared against a baseline performance. For example, use water-saving WCs, tap aerators, low-flow showers, waterless urinals, and greywater/rainwater for recycling non-potable water.
Our expertise in smart water metering and data analytics allows us to monitor and analyse water consumption patterns, providing valuable insights to identify water-saving opportunities and track progress towards reduction targets.
Installing our device on the main meter earns you 4 points.
Sub-metering building areas consuming 10% or more of the building's total water demand, or metering multi-tenant buildings per tenanted area, achieves an additional 2 credits.
Up to 4 credits (each) are available based on the water efficiency of the following assets to reduce overall water consumption in the building:
WAT02 - Water-efficient equipment: toilets
WAT03 - Water-efficient equipment: urinals
WAT04 - Water-efficient equipment: hand washing basins
WAT05 - Water-efficient equipment: showers
WAT06 - Water-efficient equipment: white goods
Our experience in specifying and installing water-efficient fixtures can help building owners select and implement the most appropriate solutions to achieve significant water savings.
Up to 4 credits for installing a robust leak detection system, which plays a vital role in conserving water resources. By promptly identifying and addressing leaks, buildings can significantly reduce water wastage, contributing to a more sustainable water footprint. 1 credit has traditionally been given for a leak detection system that can detect a major water leak on the mains water supply within the building and/or between the building and the utilities water meter.
Our advanced leak detection technology, including smart metering and real-time monitoring, can quickly identify and locate leaks, enabling prompt repairs and minimising water wastage, potentially enabling you to achieve the full 4 credits after a complete calendar year.
Up to 4 credits for proactive measures to prevent leaks. Proper installation and maintenance of flow control devices, whether in sanitary fittings or larger residential complexes, are essential for minimising water loss and ensuring the longevity of plumbing systems.
Our LeakNet system goes beyond traditional leak prevention methods. With AI-powered monitoring, real-time alerts, and automatic shut-off capabilities, LeakNet actively identifies and stops leaks before they cause significant damage or water wastage. This proactive approach aligns perfectly with the BREEAM focus on minimising water loss and ensuring the longevity of plumbing systems.
Up to 4 credits can be awarded depending on the extent and effectiveness of the isolation valve strategy within the building's water supply system, which allows controlled shut-off of specific sections of the water supply, enabling targeted maintenance or repairs without disrupting the entire system. 1 credit has traditionally been given for installing a flow control device to each WC area/facility so that water is only supplied when needed.
Our smart shut-off valves seamlessly integrate into any plumbing system, providing the isolation capabilities necessary for targeted maintenance and repairs.
This not only meets the traditional BREEAM requirement for isolation valves but also enhances it with intelligent control and automation.
By enabling quick and precise shut-off of specific sections, LeakNet minimises disruption and water wastage during maintenance activities, maximizing the potential for achieving up to 4 credits.
The automatic shut-off functionality also serves as an innovative flow control device, securing an additional credit for controlling water supply to WC areas.
Up to 4 credits for using alternative water sources and efficient water-using technologies. Rainwater harvesting, greywater recycling, and the use of water-efficient fixtures are examples of strategies that can substantially decrease reliance on mains water supply.
While we don't directly address alternative water sources, LeakNet's ability to dramatically reduce water wastage through automatic shutoff and leak prevention contributes to lowering mains water consumption.
By minimising unnecessary water loss, LeakNet supports the overarching goal of WAT10, contributing to achieving the maximum credits available.
Up to 4 credits for accurate monitoring and reporting of water consumption data, which is fundamental to effective water management. By tracking consumption patterns, building owners and operators can identify areas for improvement and implement targeted water-saving measures. This will include internal sub-meters to monitor the impacts of inefficiencies and leakage and encourage more effective water management.
Our smart metering and data analytics capabilities can provide detailed insights into water consumption patterns, facilitating the identification of inefficiencies and enabling targeted water-saving interventions.
Up to 4 credits for re-using water for non-potable purposes, such as irrigation or toilet flushing, reduces the demand on treated water supplies. This credit promotes innovative solutions for sustainable water sourcing.
Our experience in monitoring water recycling systems, such as greywater and rainwater harvesting solutions, can help track inefficiencies in these systems and maximise the reuse of water to reduce environmental impact.
Up to 4 credits for standardised reporting of water consumption, benchmarking, and comparison across different buildings and portfolios. This transparency encourages continuous improvement in water efficiency and supports informed decision-making.
Obtain 2 credits by using our data management and reporting tools to automate the collection, analysis, and reporting of water consumption data, providing clear and actionable insights to support decision-making.
Earn 1 extra credit when you report on it internally, and another credit if you publish this information in an annual report.
A comprehensive water strategy goes beyond individual measures by establishing a holistic approach to water management. It includes regular maintenance of water systems, water efficiency, water reuse, and leak detection. The strategy should also include a plan for monitoring and reporting water consumption ensuring optimal performance and longevity, as well as promoting awareness and behavioral changes among building occupants to foster a water-conscious culture.
Up to 8 credits are available depending on the comprehensiveness of the water strategy and the inclusion of specific elements such as:
A proactive maintenance policy for installed water systems
Targets for reducing water consumption
A plan for monitoring and reporting water consumption
A plan for engaging building occupants in water conservation efforts
Our holistic approach to water management and expertise in water efficiency, reuse, and leak detection can help building owners develop and implement comprehensive water strategies that achieve long-term sustainability and cost savings.
Every building’s risk profile and budget differ. Unlike one-size-fits-all systems, Quensus engineers a bespoke leak-detection solution around your insurer’s requirements and cost constraints - saving you thousands in wasted water and premiums. There is unlimited number of options, but we have simplified leak prevention into our four main tiers:
A combination of bronze, silver and gold will provide the most effective leak prevention system available.
Automatic Flow Monitoring with Smart Shutoff Valves on the boosted supply to each unit/apartment. The most effective solution post-handover over the lifetime of the building.
Automatic Flow Monitoring with Smart Shutoff Valves on the boosted supply to each floor (or each riser if plumbing is vertically fed). Ideal during construction because each floor can be isolated individually.
The absolute minimum you should be looking for is Automatic Flow Monitoring on the Mains Cold Water System and Boosted Cold Water System for the whole building. This is covered in the BREEAM WAT03 standard.
