    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 buildings, infrastructure, and communities. Its credit-based methodology awards points for compliance with criteria, weighted by category impact, yielding ratings from Pass to Outstanding.

    Key Components

    • 10 core categories: Management, Health & Wellbeing, Energy, Transport, Water, Materials, Waste, Land Use & Ecology, Pollution, Innovation.
    • Evidence-driven credits with prerequisites, supported by technical manuals and KBCNs.
    • Schemes for lifecycles: New Construction, In-Use, Refurbishment, Infrastructure.
    • Third-party certification via licensed assessors and BRE audits.

    Why Organizations Use It

    Drives ESG compliance, net-zero alignment, asset value uplift (up to 30%), energy savings (22-33%). Mitigates regulatory risks, enhances market differentiation, builds stakeholder trust through verified performance.

    Implementation Overview

    Early assessor appointment, phased pre-assessment to certification. Applies globally with local adaptations; suits all sizes via tailored schemes. Involves evidence management, training, and In-Use recertification every 3 years. (178 words)

    AS9100 Details

    What It Is

    AS9100D (AS9100:2016) is the global quality management system (QMS) standard for aviation, space, and defense organizations. It extends ISO 9001:2015 with 100+ aerospace-specific requirements, emphasizing risk-based thinking, product safety, and supply chain controls via a process-based approach.

    Key Components

    • 10-clause Annex SL structure (Clauses 4–10 core)
    • Aerospace additions: configuration management (8.1.2), product safety (8.1.3), counterfeit prevention (8.1.4), operational risks (8.1.1)
    • Dual risk layers: enterprise (6.1) and operational
    • Third-party certification with Stage 1/2 audits, annual surveillance

    Why Organizations Use It

    • OEM/contractual mandates for market access via OASIS
    • Reduces defects, rework, delivery delays; improves ROI
    • Mitigates safety risks, counterfeit threats
    • Builds stakeholder trust, enhances competitiveness

    Implementation Overview

    Phased: gap analysis, process design, training, internal audits, certification. Applies to ASD firms globally; 6–18 months typical for mid-sized orgs.
