インド北部の寮ビルを対象に、ライフサイクルアセスメント（LCA）を用いて運用・体積エネルギーと炭素排出を評価。運用段階が総排出量の73%を占め、太陽光発電の導入で96%の電力由来排出削減が可能。3つの対策で約38%の生涯排出削減を見込む。
English
Evaluates life cycle carbon emissions of a hostel building in northern India using LCA. Operational stage dominates (73% of total). Proposed mitigation: solar PV (96% reduction in electricity emissions), biogas (15.6% cooking reduction), and tree planting (full sequestration). Combined 38% lifetime reduction.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
インドの事例だが、日本の建築物LCAやゼロエネルギー建築（ZEH）の取り組みと比較可能。SSBJのスコープ1〜3対応において、建設資材の体積炭素や運用時のエネルギー削減策の参考となる。
In the global GX context
Provides a replicable LCA framework for building carbon assessment relevant to global decarbonization goals. Aligns with TCFD/ISSB focus on value chain emissions; mitigation measures (solar, biogas, sequestration) are applicable to buildings in many developing regions.

📄 Abstract（原文）
Buildings account for a significant share of global carbon emissions, yet comprehensive lifecycle frameworks for assessing their full environmental impact remain limited in the Indian context. The study evaluates the environmental impact of a residential building in the lower region of north India. This case specific framework integrates life cycle assessment (LCA) in terms of operational energy analysis, embodied energy accounting, and carbon emission estimation. A detailed material and energy inventory was compiled, with embodied energy coefficients and emission factors sourced from peer-reviewed literature. Results indicate that the operational stage dominates the building's carbon profile, contributing 73% of total lifecycle emissions driven primarily by occupant metabolic CO₂ and electricity consumption. The total carbon footprint is estimated at 12.77 million kg CO₂ equivalent, with brick and reinforced cement concrete identified as the most energy and emission intensive materials. Three mitigation strategies were evaluated: replacing grid electricity with photovoltaic panels reduces electricity related emissions by 96%; substituting LPG with kitchen waste biogas achieves a 15.6% reduction in cooking emissions; and plantation of 90 mature trees enables full carbon sequestration. Collectively, these measures reduce the building's lifetime emissions by approximately 38%. The proposed framework offers a replicable, case specific approach to carbon assessment and mitigation planning, applicable to other residential buildings seeking to align with sustainable construction goals.
