BREEAM In-Use vs BREEAM New Construction
Explore the key differences between BREEAM In-Use and New Construction to choose the right sustainability assessment for your building project.
Key Differences Explained
As sustainability becomes a driving force in the built environment, the need for reliable certification systems has never been greater. BREEAM* is one of the world’s leading sustainability assessment methods. However, understanding the difference between BREEAM In-Use and BREEAM New Construction can be crucial when planning or upgrading your project.

Understanding the Basics
What is BREEAM New Construction?
BREEAM New Construction is designed for buildings that are being newly built or undergoing major refurbishments. It assesses environmental performance across design, construction, and early operational phases, covering categories like:
- Energy efficiency
- Water usage
- Materials
- Waste
- Pollution
- Health and wellbeing
This scheme is ideal for developers and designers who want to integrate sustainable practices from the ground up and gain recognition for doing so.
Understanding the Basics
What is BREEAM In-Use?
BREEAM In-Use, on the other hand, is tailored to existing buildings in operation. It evaluates how a building performs over time in real-world conditions and is split into three parts:
-
1: Asset performance
-
2: Building management
-
3: Occupier management
This scheme is particularly beneficial for building owners, operators and facilities managers looking to improve ongoing performance and efficiency.
Key Differences Between BREEAM In-Use and New Construction
Assessment Timing
-
New Construction: Applies before and during the construction phase.
-
In-Use: Applies after the building is operational.
Stakeholder Involvement
-
New Construction: Focuses on architects, engineers and contractors.
-
In-Use: Engages building managers, owners and occupiers.
Scope and Criteria
-
New Construction: Emphasises design intent and build quality.
-
In-Use: Measures actual performance and management practices.
Certification Validity
-
New Construction: Certification is a one-time process.
-
In-Use: Certification is renewable every 3 years, encouraging continual improvement.

Working with Encon Associates on the construction of the Heritage Skills Centre within the grounds of Lincoln castle has been a most enjoyable and rewarding experience.
The use of IESTaP project made monitoring completion of the credits far more visible and as project manager I was able to obtain reports very easily. Glenn managed the BREEAM process in an efficient manner, providing the right level of face-to-face interaction.
There is nothing but praise for Glenn’s efforts and determination and I would use this organisation as a BREEAM consultant on future projects.
