When it comes to the overall performance and rating to BREEAM for a new construction project, a number of different factors are considered, these are;
- The BREEAM rating level Benchmarks
- The environmental section weightings
- The Minimum BREEAM standards
- The BREEAM assessment issues and credits
The combination of the above factors will ultimately determine the BREEAM rating of the project, below is an overview of the ratings that can be achieved and benchmarks for the ratings as set out in BREEAM. figures taken from BREEAM table 2.3
BREEAM RATNG | % Score |
Outstanding | ≥ 85 |
Excellent | ≥ 70 |
Very Good | ≥ 55 |
Good | ≥ 45 |
Pass | ≥ 30 |
Unclassified | <30 |
BREEAM rating benchmarks enable a client and all other stakeholders to compare the performance of a newly constructed building with other BREEAM rated buildings, and the typical sustainability performance of a stock of new non-domestic buildings in the UK. In this respect each BREEAM rating broadly represents performance equivalent to:
1. Outstanding: Lessthan the top 1% of UK newnon-domestic buildings(innovator)
2. Excellent: Top 10% of UK newnon-domestic buildings(best practice)
3. VeryGood: Top 25% of UK newnon-domestic buildings(advanced good practice)
4. Good: Top 50% of UK newnon-domestic buildings(intermediate good practice)
5. Pass: Top 75% of UK newnon-domestic buildings(standard good practice)
An unclassified BREEAM rating represents performance that is non-compliant with BREEAM, in terms of failing to meet either the BREEAM minimum standards of performance for key environmental issues or the overall threshold score required to achieve at least a Pass rating.
