Changes to BREEAM - How it affects you

On Tuesday 27th May a new version of BREEAM New Construction was launched by the BRE.

 

The final date for registering your project for assessment under the previous BREEAM 2011 version is Monday 30th June for all countries in the UK except Scotland. Current projects registered under BREEAM 2011 will remain valid for assessment for 5 years from the expiry of BREEAM 2011, i.e. June 2019.

 

The 2014 scheme has been updated to reflect improvements in industry and building regulations standards. The new guidelines also allow for a greater range of documentary evidence to be submitted without being prescriptive.   

 

Key changes to the scheme include:

 

- Country specific (England, Northern Ireland, Scotland, Wales) and UK Manuals available.


- Shell and Core buildings are now defined as either ‘Shell only’ or ‘Shell and core’ and have their own scope-specific assessment criteria and credit weightings.


- The Management section has been restructured to better align with the building procurement process from Project Brief to Aftercare and includes a new credit for reporting the project’s predicted capital cost.


- The Health & Wellbeing section has been updated in line with new standards for thermal comfort and includes an optional alternative to the average daylight factor benchmark.


- Hea 04 – Water Quality, which related to the provision of fresh water, has been removed.


- The Energy section has been updated in line with Part L 2013. The requirement for a percentage of the energy generated for the building to be from renewables has been removed from Ene 04 – Low and Zero Carbon Technologies (now called Low Carbon Design), and is instead encompassed in the Ene 01 – Reduction of Energy Use and Carbon Emissions calculations.


- The Materials section has undergone some substantial changes. The Responsible Sourcing of Materials (Mat 03) calculation criteria has been simplified with options depending on the amount of information known on volumes of materials.


- A new credit Mat 06 - Material efficiency - includes the requirement to identify, investigate and implement measures to optimise material use across all design stages of the project.


- Two new credits in the Waste section identify building structure and fabric resilience to climate change and a functional adaptability assessment identifying possible future changes the building may see.

 

- A Resource Management Plan, following the same structure as a Site Waste Management Plan (SWMP), is still required for Wst 01 – Construction Waste Management despite the repeal of legislation in England surrounding SWMPs.

 

The percentage weightings for each section have been updated to reflect recent changes to the building regulations which takes a more holistic approach placing less of an emphasis on energy. This results in a decrease in weighting for the Energy section and an increase in the Transport, Water, Materials and Waste sections.  Changes to weightings are summarised in the table below:
