本研究は、ライフサイクル炭素排出評価（LCCE）と多次元性能評価を統合したスポーツ施設低炭素評価システム（SV-LCES）を提案する。EnergyPlusシミュレーションと排出係数法を用い、国家スライディングセンター（NSC）と延慶冬季オリンピック村（YWOV）に適用した。運用・保守段階が全ライフサイクル排出の56.39%を占め、炭素削減率はNSCで40.17%、YWOVで46.37%であった。AHPとグレークラスタリングによる総合評価ではNSCがグレードB、YWOVがグレードAと判定された。

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では大規模スポーツ施設の脱炭素化はまだ事例が少なく、ライフサイクル評価と多面的評価を組み合わせた本手法は、今後のZEB化やカーボンニュートラル設計に参考になる。特に運用段階の排出が支配的である点は、日本の施設運用改善に示唆を与える。
In the global GX context
This paper contributes to the global discourse on life-cycle carbon assessment for large public buildings, offering a replicable framework that aligns with TCFD/ISSB disclosure of operational emissions. It highlights the importance of O&M-phase emissions, relevant to CSRD and SEC climate disclosure requirements for real estate and infrastructure.

📄 Abstract（原文）
Large-scale snow sports venues are characterized by unique terrain, seasonal operation modes, and long service lifespan. Consequently, a comprehensive assessment method is required to account for both life-cycle carbon emissions and multi-dimensional low-carbon performance. This study proposes a Sports Venue Low-carbon Evaluation System (SV-LCES) that integrates life-cycle carbon emission evaluation (LCCE) with multidimensional performance assessment. Using engineering inventories, EnergyPlus simulations, and emission factor methods, a life-cycle carbon emission model was developed and applied to the National Sliding Centre (NSC) and Yanqing Winter Olympic Village (YWOV), with the latter constructed as a supporting venue for the NSC. Carbon hotspots were identified, and an evaluation system was established through the Analytic Hierarchy Process (AHP) and LCCE combined weighting and grey clustering. The results show that the operation and maintenance stage was the dominant contributor to the life-cycle carbon emissions, accounting for 56.39% of the total. The calculated carbon emission reduction rates of the NSC and YWOV were 40.17% and 46.37%, respectively, indicating a relatively small difference. However, after the low-carbon performance of the venues was comprehensively evaluated, SV-LCES distinguished their performance levels as Grade B for NSC and Grade A for YWOV. The proposed framework offers a holistic approach to low-carbon evaluation of large-scale sports venues and other energy-intensive public buildings.
