BREEAM Details
What It Is
BREEAM (Building Research Establishment Environmental Assessment Method) is a science-led sustainability certification framework for the built environment. Developed by BRE in 1990, it assesses environmental, health, and resilience performance across building lifecycles using a credit-based, weighted scoring methodology.
Key Components
- Core categories: Management, Health & Wellbeing, Energy, Transport, Water, Materials, Waste, Land Use & Ecology, Pollution, Innovation.
- Credits earned via evidence against issue criteria; weighted scores yield ratings (Pass to Outstanding).
- Schemes for New Construction, In-Use, Refurbishment, Infrastructure, Communities.
- Third-party model: licensed assessors submit; BRE audits and certifies.
Why Organizations Use It
Drives ESG compliance, net-zero alignment, asset value uplift (up to 30% premiums), operational savings (22-33% energy). Mitigates regulatory risks, enhances tenant appeal, builds investor trust via audited benchmarks.
Implementation Overview
Phased: pre-assessment, design integration, construction evidence, certification. Applies globally with local adaptations; early assessor appointment key. Targets all sizes via tailored schemes; requires evidence rigor and training.
ISO 17025 Details
What It Is
ISO/IEC 17025:2017 is the international standard titled General requirements for the competence of testing and calibration laboratories. It provides an accreditation framework ensuring competence, impartiality, and consistent operation. The risk-based, performance-oriented approach integrates general, structural, resource, process, and management requirements into eight elements.
Key Components
- Impartiality/confidentiality (Clause 4), structure (5), resources (6: personnel, facilities, equipment, traceability), processes (7: methods, uncertainty, validity, reporting), management system (8: Option A/B).
- Built on technical validity, metrological traceability, and continual improvement.
- Scope-specific accreditation by ILAC bodies via assessments and surveillance.
Why Organizations Use It
- Enables global acceptance of results, market access, regulatory compliance.
- Mitigates risks from invalid data affecting safety, trade, liability.
- Builds stakeholder trust, competitive differentiation via credible competence.
Implementation Overview
- Phased: gap analysis, documentation, validation, training, audits.
- Applies to all lab sizes in testing/calibration worldwide.
- Involves proficiency testing, witnessed audits for accreditation.
