本研究はスペインの新築住宅を対象に、将来シナリオを用いたライフサイクルアセスメント（LCA）により体現炭素と運用炭素を評価。BIMを活用した6シナリオの比較から、両排出量を効果的に削減する経路を特定し、政策立案や業界向けの脱炭素戦略に資する知見を提供する。
English
This study assesses future embodied and operational carbon emissions of new residential buildings in Spain using prospective Life Cycle Assessment (LCA) across six scenarios. A BIM-based workflow quantifies environmental impacts, identifying development pathways that effectively reduce both emission types. The findings offer evidence-based strategies for policymakers and industry stakeholders to decarbonize the building sector.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建築分野の脱炭素化にも示唆を与える。ライフサイクル全体の炭素排出量を定量化する手法は日本でも応用可能だが、スペイン特有の建築慣行やデータに基づくため、そのまま適用には注意が必要。
In the global GX context
This paper contributes to the global discourse on building decarbonization by providing a comprehensive LCA framework that integrates embodied and operational carbon. It demonstrates how scenario analysis and BIM can inform policy and design choices, relevant to jurisdictions like the EU's Energy Performance of Buildings Directive (EPBD) and other national building codes.
👥 読者別の含意
🔬研究者:Researchers can adopt the prospective LCA methodology and scenario modeling for building carbon assessments in other regions.
🏢実務担当者:Practitioners can use the BIM-LCA workflow to evaluate carbon impacts of new building projects and identify reduction opportunities.
🏛政策担当者:Policymakers can leverage the identified effective scenarios to set evidence-based targets for building sector decarbonization.
📄 Abstract（原文）
Given the urgent need to reduce CO₂ emissions from buildings and to anticipate future growth trends and their associated carbon footprint, this study explores potential future scenarios for new residential construction in Spain, with a specific focus on embodied and operational carbon emissions across the building life cycle. The research assesses how different development pathways could support the decarbonization of the building sector while accounting for environmental impacts and long-term sustainability goals. To achieve this, six different future scenarios have been developed using mathematical forecasting models, including linear regression, as well as official data on growing trends. These scenarios are subsequently assessed through a prospective Life Cycle Assessment (LCA), including modules A1–A5, B2, B4, B6, and C1–C4, to quantify their potential contribution to carbon-emission reduction. A Building Information Modelling (BIM)-based workflow is applied to estimate the environmental impact of new residential buildings, integrating official data on existing building typologies, geometric characteristics, and conventional materials and construction systems used in Span. The results identify scenarios that most effectively reduce both embodied and operational carbon emissions, underscoring the critical role of the development pathways and future trends in determining decarbonisation effectiveness. The study provides insights to support policymakers, planners, and industry stakeholders in defining evidence-based strategies for the decarbonization of residential construction in Spain.
