What is BREEAM?

BREEAM, or Building Research Establishment Environmental Assessment Method, is a global standard for evaluating environmental performance in new build construction and refurbishment.

It helps organisations benchmark, prove, and improve environmental credentials across the building lifecycle through design, construction, and operation.

Jump to: How Can Quensus help me achieve maximum BREEAM credits?

BREEAM evaluates buildings performance in a variety of categories:

Water
Energy
Land Use & Ecology
Health & Wellbeing
Pollution
Transport
Materials
Waste
Management

Key Benefits of BREEAM Certification 

Achieving BREEAM certification demonstrates the environmental performance of your building while delivering significant, measurable advantages:

International / USA BREEAM In-Use scheme

We have so far focussed on the UK BREEAM scheme, but what about internationally?

The following credits apply to the International / USA BREEAM In-Use scheme and includes much more scope for leak detection.

Dropdown

BREEAM WAT 01  – Water Monitoring

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT02 - WAT06: Water-Efficient Equipment

  • 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


Quensus Advantage

  • 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.

BREEAM WAT 07 – Leak Detection System

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT 08 – Leak Prevention

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT 09 – Isolation Valves

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT 10 – Reduce Utility-Supplied Water Consumption

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT 11 – Water Consumption

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT 12 – Water Recycling

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT 13 – Water Consumption Reporting

  • 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.


Quensus Advantage

  • 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.

BREEAM WAT 14 – Water Strategy

  • 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


Quensus Advantage

  • 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.
