2. BREEAM Certification: Methodology and Requirements
2.1 Scoring Methodology
BREEAM employs a weighted scoring system to evaluate a building’s environmental performance across various categories. Each category comprises specific criteria, and points are awarded based on the building’s compliance with these criteria. The total score is then calculated by summing the weighted points from all categories. The categories include:
- Management: Focuses on the project’s management processes and their impact on sustainability.
- Health and Well-being: Assesses the indoor environmental quality and its effect on occupant health.
- Energy: Evaluates energy consumption and efficiency measures.
- Transport: Considers the building’s accessibility and impact on transportation.
- Water: Examines water usage and conservation strategies.
- Materials: Reviews the sustainability of materials used in construction.
- Waste: Looks at waste management practices during construction and operation.
- Land Use and Ecology: Assesses the building’s impact on land and local ecology.
- Pollution: Evaluates measures to reduce pollution during construction and operation.
Each category has a set of criteria with specific benchmarks, and points are awarded based on the building’s performance relative to these benchmarks. The total score determines the certification level, ranging from Pass to Outstanding. (lignacite.co.uk)
2.2 Versions and Regional Adaptations
BREEAM has evolved over time to address different building types and regional contexts:
- BREEAM New Construction: Targets new, non-residential buildings in the UK, assessing sustainability from design through to construction.
- BREEAM International New Construction: Extends the assessment to new buildings globally, excluding the UK and countries with their own BREEAM schemes.
- BREEAM In-Use: Focuses on existing buildings, evaluating operational performance and management practices.
Each version has tailored criteria to suit the specific characteristics and challenges of the building type and location. (en.wikipedia.org)

The discussion of regional adaptations within BREEAM is particularly interesting. How does the weighting of different categories shift to reflect the specific environmental priorities of a region, such as prioritizing water conservation in arid climates versus energy efficiency in colder ones?
Thanks for raising this key aspect. The category weightings are indeed adjusted! An arid region might significantly increase the Water category’s weight, while a colder climate might prioritize Energy. This tailored approach ensures BREEAM certifications genuinely address local environmental needs, rather than applying a uniform standard globally. Do you think there are any regions where the existing categories are insufficient?

The report mentions BREEAM’s adaptability to different building types. How are conflicts resolved when a building project seeks certification under both ‘New Construction’ and ‘In-Use’ standards simultaneously or sequentially?
That’s a really interesting question. Addressing conflicts between ‘New Construction’ and ‘In-Use’ certifications often involves a phased approach. Initial design focuses on ‘New Construction’ criteria, followed by ‘In-Use’ assessments as the building becomes operational. Clear communication and documentation are essential for navigating overlaps. What mechanisms are you using?
