What is BREEAM? A plain-English guide for real estate

BREEAM is the world's longest-established sustainability assessment for the built environment. If you own, manage, or finance commercial real estate in Europe, you have almost certainly seen the label - and increasingly, investors, tenants, and regulators expect you to have one.

This guide explains what BREEAM actually is, who runs it, what it measures, and why it has become the de facto sustainability passport for European real estate.

What does BREEAM stand for?

BREEAM stands for Building Research Establishment Environmental Assessment Method. It was launched in 1990 by BRE (the Building Research Establishment), a UK building science organisation. It predates LEED by eight years and is widely considered the original green building rating system.

Today more than 2.3 million buildings have been registered for BREEAM assessment across roughly 90 countries, with the strongest concentrations in the UK, the Netherlands, Spain, Germany, and the Nordics.

Who owns and issues it?

BREEAM is owned by BRE Group (specifically BRE Global Ltd), the UK-based Building Research Establishment. Outside the UK, BRE licenses National Scheme Operators (NSOs) to adapt the methodology to local building codes, climate, and regulations:

• Netherlands - Dutch Green Building Council (DGBC), operates BREEAM-NL
• Spain - Instituto Tecnológico de Galicia (ITG), operates BREEAM-ES
• Germany / Austria / Switzerland (D-A-CH) - TÜV SÜD (which acquired DIFNI in 2016), operates BREEAM DE / AT / CH for both New Construction and In-Use. BREEAM DE Neubau launched in 2018.
• Norway - Norwegian Green Building Council (NGBC), operates BREEAM-NOR
• Sweden - Swedish Green Building Council (SGBC), operates BREEAM-SE
• Rest of world - BRE Global itself operates the BREEAM International schemes, used in any country without a local NSO

Certificates are not self-issued. A licensed BREEAM Assessor (or BREEAM Auditor in the D-A-CH region) collects evidence, scores the asset against the relevant scheme manual, and submits it for independent quality assurance by the NSO - which then issues the certificate.

What does BREEAM actually measure?

BREEAM scores an asset across nine sustainability categories. The exact weighting varies by scheme and country, but the categories are consistent:

• Energy - operational energy use, carbon intensity, metering
• Health & Wellbeing - indoor air quality, daylight, acoustics, thermal comfort
• Management - sustainability strategy, commissioning, stakeholder engagement
• Transport - access to public transport, cycling, EV charging
• Water - consumption, leak detection, water-efficient fittings
• Materials - embodied carbon, responsible sourcing, durability
• Waste - construction and operational waste management
• Land Use & Ecology - biodiversity, brownfield use, ecological value
• Pollution - refrigerants, NOx emissions, flood risk, light and noise pollution

Each category is broken into credits. Hit a credit - by providing the right evidence - and you earn points. Points are weighted by category, summed, and translated into a percentage score that determines your rating.

The four BREEAM schemes you will encounter

BREEAM is not one product but a family of schemes covering the full asset lifecycle:

• BREEAM New Construction - for buildings being designed and built
• BREEAM In-Use - for existing, operational assets; recertified every three years. This is the most relevant scheme for institutional portfolio holders.
• BREEAM Refurbishment & Fit-Out - for major retrofit projects
• BREEAM Communities & Infrastructure - for masterplans and non-building infrastructure

Why investors and tenants increasingly demand it

A BREEAM certificate is no longer just a sustainability statement - it has become a financial signal. Three forces are driving demand:

• Green financing - sustainability-linked loans and green bonds typically require certification as a covenant. ING, ABN AMRO, Rabobank, and BNP Paribas all reference BREEAM in their lending criteria.
• EU regulation - the revised Energy Performance of Buildings Directive (EPBD), CSRD reporting, and EU Taxonomy alignment can all be partially evidenced through BREEAM credits, reducing duplicate compliance work.
• Tenant demand - corporate tenants with their own net-zero commitments increasingly require certified space. European research finds rental premiums of 6–12% and capital value premiums of 14–16% (CBRE). A Dutch BREEAM-NL study using DGBC and CBRE data (2015–2022) found an average 10.3% rental premium, ranging 5.1–12.6% across the five largest Dutch cities.

How long does certification take?

For a single existing asset, a BREEAM In-Use assessment typically takes 4 to 9 months end-to-end - scoping, evidence gathering, assessor scoring, quality assurance by the NSO, and certificate issuance. Well-prepared assets can land closer to 3–6 months; assets with incomplete data often run 6–12 months. At portfolio scale - 50, 100, or 500 assets - that timeline is the single biggest bottleneck, which is why owners increasingly use AI workspaces like Sustainix to compress the evidence and gap-analysis phases.

What BREEAM is not

Three common misconceptions worth clearing up:

• BREEAM is not an energy label. Energy labels (like the Dutch energielabel) measure predicted energy performance against a baseline. BREEAM is broader - it measures management, health, water, materials, and more.
• BREEAM is not LEED. They cover similar ground but use different methodologies, weightings, and rating scales. LEED is dominant in North America; BREEAM is dominant in Europe.
• BREEAM is not net zero. A BREEAM certificate does not prove a building is net-zero carbon. Net zero is a separate, complementary framework (e.g. CRREM, UKGBC NZCB).

The bottom line

BREEAM is a third-party verified, points-based sustainability assessment that has become the European market standard for proving a building is well-run on environmental and social criteria. Whether you treat it as a compliance exercise or a value-creation lever depends on how strategically you use the results - but ignoring it is rarely an option anymore.
