Sector Specific BREEAM Methodologies

A school or a hospital is different to a house. That is why BREEAM has several methodologies for different types of project. For example there are numerous walling systems that one can use when building a house that are not applicable when building a hospital.

Energy use of the building during it operational life span will also be different. A school does not use a great deal of hot water per pupil, but a hospital will use considerably more, as lots of people need to washed for example. The different BREEAM methodologies take these differences in to account , and make sure that sustainability features are apt for the type of project they are incorporated.

For example "Building fabric performance and avoidance of air infiltration" is not assessed under BREEAM for Offices, but it is is BREEAM for education.

Below is comparison of measures considered when assessing Transport;

Offices

Accessibility is assessed on distance from "nodes" of public transport (this is the same for schools) but office worker travel times are considered for example people come and go from offices all day, but at schools they leave in one go at the end of the day (simplified obviously).

School

Special Considerations Such as: Where there is a dedicated bus service to and from the school at the beginning and end of the school day, one credit can be awarded regardless of the building’s public transport Accessibility Index.

Hub: BREEAM Methodologies and Technical Standards

BREEAM methodologies provide the scientific framework required to validate the environmental performance of a building. At Southwest Environmental Limited (SWEL), we leverage these standardized assessment methods to ensure that developments achieve high ratings while meeting local planning requirements. Our approach integrates multiple environmental disciplines to streamline the certification process.

Ecological Methodology (LE 02 to LE 05)

The assessment of ecological value is a primary component of the BREEAM framework. We utilize specific methodologies to identify site potential and implement enhancements that secure long-term biodiversity.

• Ecological Value Assessment: Utilizing a Preliminary Ecological Appraisal (PEA) to establish the baseline condition of a site.
• Enhancement and Auditing: Applying the Biodiversity Net Gain (BNG) metric to quantify and verify ecological improvements.
• Management Planning: Developing a Landscape and Ecological Management Plan (LEMP) to satisfy BREEAM requirements for long-term habitat protection.

Material and Energy Methodologies

BREEAM emphasizes the reduction of environmental impacts through informed material selection and energy-efficient design. Our technical reports provide the evidence base for these credits.

• Life Cycle Performance: Conducting a Whole Life Carbon Assessment (WLCA) to meet Mat 01 requirements for embodied carbon.
• Energy Strategy: Implementing robust Energy Strategies that align with the "Be Lean, Be Clean, Be Green" hierarchy.
• Fabric Performance: Analyzing Fabric Energy Efficiency to ensure the building envelope exceeds minimum thermal standards.

Pollution and Water Management (Pol 03 and Wat 01)

Effective management of site runoff and pollution is essential for a high BREEAM rating. Our methodologies ensure that site-specific risks are identified and mitigated.

• Hydrological Assessment: Integrating a site-specific Flood Risk Assessment (FRA) to satisfy Pol 03 requirements.
• Drainage Design: Developing a Sustainable Drainage Systems (SuDS) Strategy to manage surface water and achieve Wat 01 credits.
• Pollution Prevention: Implementing Construction Environmental Management Plans (CEMP) to protect local watercourses and air quality.

Professional Technical Authority

With a 15-year track record and over 900 projects completed, Southwest Environmental Limited provides the professional accreditation required for BREEAM consultancy. Our technical authority is backed by memberships in the IES, IAQM, and BIAC, ensuring that all reports meet the rigorous standards expected by planning officers and BREEAM assessors. We combine advanced modeling with practical site knowledge to deliver verifiable environmental performance for our clients.
