BREEAM New Construction: Standard Structure and Scheme Overview
What the standard is
BREEAM New Construction is a third-party certified environmental rating for non-domestic buildings at the design and post-construction stages. Candidates must know its architecture: a set of environmental categories (Management, Health and Wellbeing, Energy, Transport, Water, Materials, Waste, Land Use and Ecology, Pollution, and Innovation), each containing assessment issues with a defined number of credits. Credits are weighted per category to reflect relative environmental importance, then normalised against the building's floor area to produce a percentage score, which maps to a rating band from Pass through Good, Very Good, Excellent to Outstanding.
Concepts to master
Know the difference between the design-stage rating (interim certificate) and the post-construction rating (final certificate). Understand the environmental weighting system and why it changes between scheme versions. Recognise mandatory minimum standards: certain issues require minimum credit levels regardless of overall score, and energy and water have specific minimum performance requirements. Understand the Innovation category (additional credits for exemplary performance beyond the standard) and how it feeds into the total.
Traps in questions
Common traps include confusing the number of categories across scheme versions, assuming a high overall score alone guarantees a rating when a mandatory minimum is missed, and mixing up BREEAM New Construction with BREEAM In-Use or Refurbishment and Fit-Out. Another trap is treating credits as directly comparable across categories without applying weightings.
Rule of thumb
Remember: overall score determines the band, but mandatory minimums can veto it. Always check both the weighted total and the minimum standards before predicting a rating.
