Online Resource —Prospective life cycle assessment of circular energy-waste systems in university buildings: a scalable workflow using openLCA and Brightway2

This deposit contains the numeric exports that accompany the Electronic Supplementary Material (Online Resource 1, OR1). It includes high‑precision per‑scenario statistics exported from openLCA 2.5 (AusLCI v1.42; IPCC 2013 GWP100) and diagnostic outputs from a lightweight Brightway2 algebraic metamodel used for paired contrasts and sensitivity screening. All symbols, units, scenario labels, and settings match OR1 Tables S0–S4 and Figures S1–S3. Reported values are anchored to GUI unit factors; optional alignment constants are provided for consistency checks only.

Directory layout

ESM_openLCA_exports/ — per‑scenario Monte Carlo statistics (CSV). Columns: mean, std, p5, p50, p95, n (n = 2,000 per scenario). Reporting basis: GUI unit factors CF_grid = 0.851 / 0.445, CF_landfill = 0.833, CF_compost = 0.046; baseline treats rooftop PV as subtract‑only (CF_PV = 0), with a side‑by‑side PV‑included sensitivity (CF_PV = 0.045). 

ESM_Brightway2_exports/ — diagnostic outputs from the algebraic metamodel: paired scenario contrasts (with CRN), SRC/SRRC sensitivity, and a check‑only alignment to reproduce openLCA means within ±0.5 % (n = 3,000, SEED = 2025). Do not mix alignment constants with GUI‑factor reporting.

Figs. S1–S3: Foreground network (S1); GUI evidence for QLD current LV (S2, 0.851 kg CO₂‑eq·kWh⁻¹) and for QLD‑2050 mix (S3, 0.445 kg CO₂‑eq·kWh⁻¹).

Tables S0–S4: scenario matrix(S0), parameters/distributions(S1), unit factors(S2), MC settings(S3), and consistency check (S4) for cross‑tool agreement (±0.5 %).
