What is BREEAM In-Use?

BREEAM In-Use is an environmental assessment method that enables property investors, owners, managers and occupiers to determine and drive sustainable improvements in the operational performance of their buildings. It provides sustainability benchmarking and assurance for all building types.

The Value of BREEAM In-Use

Lower running costs

BREEAM In-Use identifies ways to continuously improve efficiencies through monitoring, evaluation and setting performance targets that are assessed against tangible benchmarks.

Increased asset value and recognition

Improved asset performance means that BREEAM-certified buildings support lower vacancy rates, higher rental premiums and provide a reputable and meaningful route to Environmental Social Governance (ESG).

Improved health and wellbeing

High standards of internal environments, such as air quality and lighting, and the promotion of active, healthy lifestyles are recognised to improve wellbeing, productivity and satisfaction of people living or working in the asset.

Recognising resilience

BREEAM In-Use considers an asset’s exposure to a range of risks from climate change and other drivers including flooding, pollution, natural hazards and security.

Supporting a circular economy

BREEAM In-Use adopts circular economy concepts to rethink how resources are considered, from a linear ‘take-make-waste’ approach to a more efficient and circular approach towards waste and materials.

Bridging the performance gap

Measuring and understanding the performance of buildings helps achieve designed levels of performance. BREEAM In-Use users can start planning improvements and stimulating positive change based on actual performance data and transform modelled outputs into actual outputs.

Leading the way to Net-Zero Carbon

The world is heading for a Net-Zero Carbon future in response to global challenges and growing demand from consumers, governments and investors. BREEAM In-Use provides a pathway towards achieving operational Net-Zero Carbon and beyond, using an integrated energy tool to measure stepped performance that is based on robust research, development and many years of experience as a world-leading environmental assessment methodology.

How it works

The BREEAM In-Use (BIU) assessment process operates through an online platform that enables users to register assets and assess them based on the part(s) chosen. The secure online platform has dynamic scoring which produces instantaneous outputs and includes reporting functionality that allows the user to track and improve the performance of their assets.

Upgrade from BREEAM In-Use 2015 to Version 6

Building on years of experience

Since its creation in 2009, BREEAM In-Use has been used by thousands of assets in over 30 countries to benchmark, improve and certify their sustainability performance and to showcase high standards of ESG performance. The latest edition of BREEAM In-Use, Version 6, builds on this to keep encouraging and supporting the improvement of all buildings, wherever they are in their sustainability journey.

Version 6 brings major improvements to BIU’s standards for commercial buildings and a brand-new offering tailored for residential assets. In doing so, BIU continues to create, protect and grow asset value by encouraging investment in the asset’s performance, not just in obtaining a certificate.

How Version 6 drives performance forward

Discover a summary of the changes made for BREEAM International In-Use 2015 and BREEAM International In-Use: Commercial Version 6, or view our webinars below.

If you are a licensed BREEAM In-Use Assessor, you have access to a comprehensive online training to update you on the changes from 2015 to Version 6, via the BRE Academy. An interactive user guide for the BIU online platform is available, for free, when you register or log in – see ‘Getting Started’.

How BIU measures performance

BREEAM In-Use ratings are scored against key environmental categories that provide a comprehensive assessment of a building’s environmental performance and management.

The BREEAM In-Use online platform takes users through a set of questions that are used to assess asset performance against these categories to determine its overall BREEAM In-Use rating from good and best practice to beyond.

Backed by scientific research and peer review

BREEAM In-Use is developed by the Building Research Establishment (BRE) using research, science, independent peer-review and with insight and input from clients, assessors and other stakeholders.
