インドネシアの建築基準と政策に整合したグリーンビルディングのカーボンフットプリント定量化フレームワークを提案。50年全ライフサイクル炭素は15,302 tCO2e（1,510 kgCO2e/m2）。運用段階が68%を占め、20%のグリッド脱炭素化と30%のセメント代替により約20%削減可能。
English
Presents an LCA-based framework for quantifying carbon footprint of green buildings aligned with Indonesian building codes. Applied to an 8-story university building, total 50-year carbon is 15,302 tCO₂e (1,510 kgCO₂e/m²). Operational energy dominates (68%), and combined grid decarbonization (20%) and cement substitution (30%) can reduce whole-life carbon by ~20%.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
インドネシアの建築基準（PP 16/2021, Permen PUPR 21/2021）に対応したLCAフレームワーク。日本の建築物LCA（CASBEE等）やSSBJのスコープ3排出算定への応用可能性を示唆。
In the global GX context
Provides a policy-ready LCA framework tied to Indonesian building regulations. Globally, it demonstrates how to operationalize national building codes for carbon quantification, relevant for countries developing standards (e.g., ISSB, CSRD) and for benchmarking building decarbonization.

📄 Abstract（原文）
This study presents a life cycle assessment (LCA)-based framework to quantify the carbon footprint of green buildings in Indonesia, explicitly aligning the model with national building standards and policy contexts. The framework integrates Indonesian standards and national emission factor resources into a stage-wise LCA (embodied, operational, and end-of-life) suitable for building practitioners and researchers. Applied to the Engineering Tower at Sriwijaya University (Palembang), an 8-story, 10,141 m² reinforced concrete educational facility, the framework was validated across life cycle stages A1-A5, B1-B7, and C1-C4 using localized inventory data, including the South Sumatra grid emission factor (0.78 kgCO₂e/kWh) and material take-offs from project documentation.The 50- year whole-life carbon totals 15,302 tCO₂e, equivalent to 1,510 kgCO₂e/m² (30.2 kgCO₂e/m²·year). Operational energy (B6) dominates at 68%, followed by embodied materials (A1-A5) at 24%, and end-of-life (C1-C4) at 5%. Sensitivity analyses demonstrate that a combined scenario of 20% grid decarbonization and 30% cement substitution (fly ash/slag) can reduce whole-li*fe carbon by approximately 20%.The IGBC-LCA framework translates Indonesia's Green Building provisions (PP 16/2021; Permen PUPR 21/2021) into a quantitative, policy-ready approach for benchmarking, early-stage optimization, and national decarbonization roadmap development. This study demonstrates how standardized, code- aware LCA improves comparability and decision-making while identifying the most influential life cycle stages for carbon reduction strategies.
