A bit of news for you all: A tougher version of BREEAM (BRE Environmental Assessment Method), the UK's most popular method of measuring a building's green credentials, was released last week. A summary of the changes made are:
- The weightings given to each area of credit were changed to give more emphasis on energy efficiency
- Mandatory credits were introduced (the equivalent of LEED prerequisites)
- A second stage was brought into the certification process, so that certification occurs post construction as well in addition to design stage review.
- Introduction of shell only assessments
- A BREEAM Outstanding rating has been introduced (above Excellent rating)
The change making most waves in the UK press is the introduction of more credits relating to energy efficiency. Previously projects could have been awarded BREEAM excellent but still been energy inefficient buildings. The new credits include benchmarks for CO2 emissions, which will align with the the new Environmental Performance Certificates (previously written about on this blog here) introduced in the UK.
