BREEAM is sometimes referred to as BREEAM Assessors, BREEAM Rating, BREEAM Assessment Ratings, BREEAM Reports, BREEAM Assessments.
What Does BREEAM Stand For?
First published by the Building Reseearch Establishment (BRE) in 1990 covering buildings across Egham, BREEAM stands for Building Research Establishment's Enviromental Assement Method.
How Is BREEAM Assessed?
Covering a range of environmental issues in Egham, BREEAM looks at a building's impact on transport, waste, energy, health, water, pollution, materials, management and ecology to assess whether a building is Outstanding, Excellent, Very Good, Good or a Pass. 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?
It's the hope that the BREEAM assessment will help building owners and designers improve their carbon footprint across Egham and make better use of their resources. A BREEAM certification is a way of validating how good a building is in terms of the environmental impact through a globally recognised standard.
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.
What Is A BREEAM Rating?
It used to be that 'Good' was the maximum level that could be achieved with 100% being the maximum score in Egham from a BREEAM assessment. However, in 2008, a new 'Outstanding' category was added - although the percentages required for each level remained the same.
The BREEAM ratings for a new, non-domestic building in Egham 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%)
How To Achieve BREEAM Excellence
The scoring for a BREEAM assessment in Egham is as follows:
- Outstanding: 85%+
- Excellent: 70%+
- Very Good: 55%+
- Good: 45%+
- Pass: 30%+
- Unclassified: <30%
