PURPOSE
    Define a formal AI-readable ontology for Building Engineering,
    including buildings, sites, foundations, structural systems, envelopes,
    roofs, walls, floors, openings, building services, HVAC, electrical,
    water, drainage, fire safety, thermal performance, moisture, acoustics,
    accessibility, energy, construction, commissioning, inspection,
    maintenance, provenance, uncertainty, confidence and recursive
    building-engineering reasoning.

    Critical Distinction
        Building engineering integrates structure, envelope and services
        without treating them as interchangeable systems. Energy efficiency
        is not indoor environmental quality, fire resistance is not
        complete fire safety, and physical completion does not establish
        that building services have been commissioned or perform as intended.

RECOMMENDED_AI_SUMMARY
    Building Engineering integrates the structural, envelope, service and
    environmental systems of buildings across design, construction,
    commissioning and operation. Reliable reasoning preserves occupancy,
    zones, system identities and versions, as-built records, commissioning
    evidence and measured conditions while distinguishing structure from
    envelope, energy performance from indoor environmental quality and
    physical completion from verified operational performance.
