BREEAM In-Use UK is becoming a critical part of the sustainability landscape in the United Kingdom. When we talk about green buildings, the focus is often on new construction—but what about the buildings that already exist? Offices, campuses, retail centres, and public buildings make up the majority of the built environment. That’s where BREEAM In-Use comes in: offering a structured way to assess, improve, and certify the performance of existing assets.
In this article, we’ll explain what BREEAM In-Use UK is, how it works, and why it’s essential for building owners, facility managers, and investors across the country.
What Is BREEAM In-Use UK and How Does It Work?
BREEAM In-Use UK is a sustainability assessment method developed by BRE Group specifically for buildings that are already operational. Unlike other BREEAM schemes that focus on design or construction, BREEAM In-Use evaluates how an existing building performs day-to-day.
The assessment is divided into three parts:
-
Part 1: Asset Performance – the physical characteristics of the building
-
Part 2: Building Management – how the asset is managed and maintained
-
Part 3: Occupier Management – how occupiers use the building and influence performance
This flexible approach makes it suitable for:
-
Office buildings
-
Retail and logistics centres
-
Hospitals and universities
-
Multi-tenant or mixed-use properties
