BREEAM
Sustainability certification framework for built environment assets
ISO 27701
International standard for Privacy Information Management Systems
Quick Verdict
BREEAM certifies sustainable buildings for environmental performance, while ISO 27701 establishes privacy management systems for PII handling. Companies adopt BREEAM for green credentials and value uplift; ISO 27701 for regulatory compliance, risk reduction, and trust.

BREEAM Details
What It Is
BREEAM (Building Research Establishment Environmental Assessment Method) is a mature, science-led sustainability certification framework for the built environment. Developed by BRE in 1990, it assesses environmental, health, and resilience performance across buildings, infrastructure, and communities using a structured credit-based methodology with category weightings.
Key Components
- **10 core categoriesManagement, Health & Wellbeing, Energy, Transport, Water, Materials, Waste, Land Use & Ecology, Pollution, Innovation.
- Credits earned per issue, weighted by impact, yielding ratings (Pass ≥30% to Outstanding ≥85%).
- Scheme-specific manuals, Knowledge Base Compliance Notes (KBCNs) for updates, third-party assurance via licensed assessors and BRE audits.
Why Organizations Use It
Drives ESG compliance, asset value uplift (up to 30%), operational savings (energy ~22-33%), regulatory alignment (e.g., EU Taxonomy), and market differentiation. Mitigates risks in planning, finance, and reputation.
Implementation Overview
Early assessor appointment, staged process (design, construction, post-occupancy), evidence submission for BRE certification. Applies globally to all sizes/types; In-Use for ongoing validity (3 years).
ISO 27701 Details
What It Is
ISO/IEC 27701:2025 is an international standard extending ISO/IEC 27001 and ISO/IEC 27002 to establish, implement, maintain, and improve a Privacy Information Management System (PIMS). It provides requirements and guidance for managing PII risks using a risk-based, PDCA (Plan-Do-Check-Act) approach, focusing on controllers and processors.
Key Components
- Clauses 4–10 for management system structure (context, leadership, planning, etc.)
- Annex A (controller controls) and Annex B (processor controls) with privacy-specific measures
- Mappings to GDPR (Annex D) and other frameworks
- Certification via accredited bodies, often integrated with ISO 27001 audits
Why Organizations Use It
- Demonstrates accountability for global privacy laws (GDPR, CCPA)
- Mitigates regulatory fines, breach risks, and vendor exclusions
- Builds trust, enables procurement wins, reduces compliance costs
- Provides auditable evidence for stakeholders
Implementation Overview
- Phased: discover/scope, design/plan, implement/operate, validate/improve
- Involves PII inventory, DPIAs, DSR processes, training
- Suits all sizes/industries handling PII; 6-12 months typical with ISMS
Key Differences
| Aspect | BREEAM | ISO 27701 |
|---|---|---|
| Scope | Sustainability in built environment (energy, health, ecology) | Privacy management for PII processing (controllers, processors) |
| Industry | Construction, real estate, infrastructure worldwide | All sectors handling PII globally |
| Nature | Voluntary sustainability certification standard | Voluntary privacy management system standard |
| Testing | Assessor-led audits, BRE QA, 3-year In-Use recertification | Certification body audits, 3-year cycle with annual surveillance |
| Penalties | Loss of certification, no legal penalties | Loss of certification, supports regulatory compliance |
