What is BREEAM In-Use?

BREEAM In-Use is the most widely used certification system for existing buildings in the world, covering more than 10 million sq m of certified space in 30 countries.

Why BREEAM In-Use?

The main benefit of BREEAM In-Use is its distinction between the performance of a building (Part 1), how it is managed (Part 2), and the impacts of occupant behaviour (Part 3).

BREEAM In-Use can be used to benchmark individual assets, asset groups or entire portfolios against a robust body of research and existing buildings across the world. It can also help to monitor performance and facilitate the continuous improvement of a property or portfolio of properties.


All non-domestic asset types that meet the following criteria:

  • 1. The asset has been occupied for at least one year and consumption data is available for the duration of that time;
  • 2. The asset contains spaces that are occupied for longer than 30 minutes at a time;
  • 3. The asset is a complete and finished structure;
  • 4. The asset is compliant with all the relevant environmental and health and safety legislation in its location.



  • BREEAM In-Use covers major environmental and other sustainability issues that affect buildings and occupants throughout their operational lifecycle. It captures data across nine key sustainability categories:
  • 1. Energy
  • 2. Water
  • 3. Ressource & Resilience
  • 4. Pollution
  • 5. Land Use
  • 6. Health & Wellbeing
  • 7. Transport
  • 8. Building Management


The scoring system is based on BREEAM In-Use credits. Each credit (209 in total) has a different impact on the overall rating. The assessments are split across three different parts, which can be undertaken independently.


  • 1. Asset Performance: The performance of the asset’s base build, construction fixtures and installed building services
  • 2. Building Management: How well a property asset is managed
  • 3. Occupier Management: Tenant engagement and reducing tenants’ environmental and wider sustainability impact
