BREEAM is sometimes referred to as BREEAM Rating, BREEAM Assessments, BREEAM Assessors, BREEAM Assessment Ratings, BREEAM Reports.
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 Bristol 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 maximum score a building can achieve in Bristol 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.
The BREEAM ratings for a new, non-domestic building in Bristol 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%)
What Does BREEAM Stand For?
BREEAM stands for Building Research Establishment's Enviromental Assement Method and was first published in 1990 by the Building Research Establishment (BRE) that covers Bristol.
How Is BREEAM Assessed?
BREEAM's aim is to educate building designers, owners and occupiers throughout Bristol about the impact their building has on the local area. To do this, BREEAM gives a rating of Outstanding, Excellent, Very Good, Good or a Pass based on transport, waste, energy, health, water, pollution, materials, management and ecology.
