A comparison of BREEAM New Construction 2014 and 2018: What this means for your project
Launched in 1990, BREEAM is the industry norm in the UK for environmental assessment and has been used to demonstrate the sustainability credentials for over half a million buildings which have been assessed and certified under the scheme. BREEAM is regularly updated to maintain its alignment with industry issues, with the most recent update released on 7th March 2018: BREEAM 2018 New Construction. This new scheme replaces the 2014 iteration.
This document summarises the key changes that have been made within the latest iteration, whilst providing a concise comparison with the 2014 scheme. The following pages also identify where we anticipate additional time and cost implications that may arise from the new scheme.
At the time of writing, the assessment scoring tool and further guidance documents had not been released by the BRE, therefore further clarifications on a number of changes are likely to be provided and updated in due course.
Please do get in touch should you wish to discuss any of the items in this document by emailing [email protected].

The update has ensured that relevant BREEAM criteria align more closely with the WELL standard.
HEA 01 Control of glare from sunlight

ENE 01 Reduction of energy use and carbon emissions: energy performance
The number of available credits for the energy performance criteria have been reduced from 12 to 9. The criteria for this section of Ene 01 is similar to 2014 and based on the BRUKL model, but with more onerous benchmarks.
The benchmarks are based on the Energy Performance Ratio for New Construction (EPRNC) and a comparison between the credits awarded for the 2014 scheme and new 2018 scheme are outlined below:
