Purpose
Offer a conceptual reflection from two ten-year research programs—one advancing environmental systems modelling for buildings, the other addressing work-life crime—to present a qualitative Impact × Crime Exposure Map. Emphasis is on how rigorous LCA/MFA practice pinpoints material–stage intersections where environmental stakes and criminogenic conditions co-occur.
Methods
We retrospectively synthesize artefacts from the environmental program—LCA with explicit system boundaries/functional units, stage-resolved results (A1–A3, A4, A5, B, C, D), data-quality grading, transport modelling—and material flow analysis (stock/flow, mass-balance checks, esp. concrete/aggregates)—with governance artefacts on transparency and custody. Mapping uses two qualitative lenses across life-cycle stages: an Impact lens (embodied carbon, resource scarcity, waste-escape potential informed by LCA/MFA) and a Crime-Exposure lens (deep subcontracting, cash-intensive tasks, weak custody, licensing/document gaps). We apply High/Medium/Low judgments.
Results
(1) A materials × stages heatmap flagging Priority where both lenses are High; (2) LCA-anchored prompts per stage (e.g., verify A4 transport assumptions against waybills; reconcile A5 processes with fuel/crew logs; close MFA mass balances at C&D before credits in D); (3) a minimum evidence pack aligned with LCA/MFA (original EPDs, batch-to-passport links, carrier licenses, waste manifests). Illustrative narratives show why prefabricated concrete at transport/installation and recycled aggregates at end-of-life frequently surface as Priority.
Implications
Rooting early-warning in LCA/MFA discipline helps teams target checks where environmental impact and exposure converge; certifiers can pair EPD claims with custody proof; public buyers can reference stage-resolved, mass-balanced evidence in tendering. The map is pilot-ready and sets a path for empirical calibration.
