本論文は、駐車インフラが建築物のカーボンフットプリント計算に与える影響を調査した。6つの集合住宅プロジェクトを分析し、駐車場が最大39%の体化排出量を占めることを明らかにした。また、EPBD委任アプローチの不整合を特定し、明確な国家ルールの必要性を強調している。
English
This study examines how parking infrastructure affects building carbon footprint calculations using six multi-apartment projects. Parking can account for up to 39% of embodied emissions and 25% of whole-life emissions. Methodological choices cause up to 32% differences in median GWP results. The EPBD delegated act creates inconsistencies favoring attached parking, highlighting the need for clear national calculation rules.

日本のGX文脈において
日本ではSSBJが建築物の炭素会計基準を策定中である。本論文の方法論的感応性に関する知見は、特に都市部の建築物に多い駐車場・地下構造物の扱いにおいて、実務者にとって直接的に有用である。
In the global GX context
This paper provides empirical evidence on how methodological choices in building LCA significantly alter GWP results, with implications for EPBD implementation globally. It highlights the need for harmonized national rules when transposing EU-level requirements.
👥 読者別の含意
🔬研究者:Researchers in building LCA will find the quantified methodological sensitivity and the identified EPBD inconsistency valuable for improving calculation guidelines.
🏢実務担当者:Corporate sustainability teams in real estate and construction can use these findings to ensure robust carbon footprint reporting for buildings with parking infrastructure.
🏛政策担当者:Regulators developing national building carbon accounting rules should consider the methodological issues raised, especially the treatment of parking infrastructure.
📄 Abstract（原文）
Parking infrastructure is an important yet often inconsistently treated element in whole-life carbon footprint assessments and broader building sustainability evaluation. With the revised Energy Performance of Buildings Directive (EPBD) introducing mandatory global warming potential (GWP) reporting, the influence of methodological choices on GWP results requires a clearer understanding. This study examines six multi-apartment residential (MAR) projects featuring four distinct parking typologies to quantify how parking infrastructure affects calculated GWP outcomes. Using EN 15804-compliant life cycle assessment (LCA) data, we evaluate four methodological approaches for including parking infrastructure in GWP calculations and the approach mandated by the delegated act supplementing the EPBD (DA-EPBD). The results show that parking infrastructure can account for up to 39% of embodied and up to 25% of whole life cycle emissions. Methodological approaches significantly influenced the GWP results, leading to differences of up to 32% in sample median values. An inconsistency in the DA-EPBD approach is identified, resulting in better GWP performance for projects including large-area attached parking infrastructure, while leading to higher GWP values for projects with detached parking. The findings highlight the sensitivity of GWP outcomes to methodological assumptions regarding parking infrastructure and underscore the need for clear national GWP calculation rules when integrating DA-EPBD requirements.
