BREEAM and BIM

The key input to the BREEAM assessment process is building and building related data.

BIM rationalises the location and format of this data and in doing so increases the potential for informed decision making compared to traditional approaches to design, construction and management. As uptake of BIM increases the processes underpinning BREEAM assessments need to adapt to make use of BIM data; realise performance improvements across a range of metrics and ultimately continue delivery of value to users.

In the context of BREEAM the key opportunity offered by increasing BIM utilisation is the potential it offers for digital building data to be processed and analysed to determine performance when the opportunity to improve performance is most cost effective prior to construction or in use management interventions. Alongside the TSB funded RegBIM project and utilising learning and output from it, work is underway to develop the IT infrastructure required to enable 3rd party construction software to automatically deliver BREEAM performance feedback to users as building data models develop. At the heart of this work is alignment of BREEAM content with industry recognised construction classification systems and interoperable data exchange standards.

Data driven construction and management also presents an unprecedented opportunity to extract building strategy and component data and link it to BREEAM performance data in order to understand successes and failures and contribute to closing the gap between design intent and in use performance. It will become possible to illustrate the relationship between components, strategies and overall building performance against BREEAM requirements, propose improvements, and also underpin and inform development of BREEAM standards in future.
