Supporting data and code for: Prospective operational life cycle assessment of energy and waste systems in a university building: an auditable workflow using openLCA and Brightway2

This record archives the full-precision scenario exports and the minimal Brightway2 diagnostic metamodel used in the study “Prospective operational life cycle assessment of energy and waste systems in a university building: an auditable workflow using openLCA and Brightway2”. The package contains per-scenario openLCA Monte Carlo outputs, a Brightway2 diagnostic metamodel for paired contrasts and screening sensitivity analysis, supporting spreadsheets, a guide file, and the minimal runtime files required for reproducibility. The case study concerns the Advanced Engineering Building at The University of Queensland, and the functional unit is one building-year. The 2 × 2 scenario design varies the electricity background (current Queensland mix versus Queensland-2050) and municipal solid-waste diversion rates (approximately 64% versus 77%). Reported per-scenario results are anchored to openLCA under independent Monte Carlo sampling (n = 2,000 per scenario). Brightway2 is used only for paired contrasts and screening sensitivity diagnostics under common random numbers (seed = 2025; n = 3,000); it does not replace the reported openLCA totals. The archived materials include the files cited in the manuscript as Online Resources 2–6 and support the results reported in Table 3, Figure 2, and Table 4.
