BREEAM: past, present and future
This document discusses BREEAM, a sustainability assessment method for buildings. It provides an overview of BREEAM's past, present and future. Key points include: BREEAM assesses whole life cycle impacts; the 2018 version integrates materials assessments and includes embodied carbon benchmarks; future versions may focus more on health/well-being and circular economy principles. BREEAM aims to continually update based on regulations, standards and stakeholder feedback to promote best practices in sustainable construction.
