Covering more than 50 countries and 250,000 buildings, BREEAM's aim is to educate building owners, designers and occupants about their impact on the local area.

What Are The Benefits of BREEAM?
BREEAM aims to show that by building with the local area in mind, though capital costs may increase, you should save on operational costs in the long-term. This limits investor costs and makes the building more attractive when it comes to selling.
A BREEAM certification is a way of validating how good a building in Clwyd is in terms of the environmental impact through a globally recognised standard. It's the hope that the BREEAM assessment will help building owners and designers to improve their carbon footprint and make better use of their resources.
What Is A BREEAM Rating?
The BREEAM ratings for a new, non-domestic building in Clwyd are:
- Pass: standard good practice (top 75%)
- Good: intermediate good practice (top 50%)
- Very Good: advanced good practice (top 25%)
- Excellent: best practice (top 10%)
- Outstanding: innovator (top 1%)
The maximum score a building can achieve in Clwyd is 100% from a BREEAM assessment. It used to be that 'Good' was the maximum level that could be achieved, however in 2008 a new 'Outstanding' category was added. The percentage required for each level remained the same despite this.
