日本語

本研究は、フィリピンの熱帯新興国における大規模商業モールのライフサイクルアセスメント（LCA）を実施し、運用エネルギー（B6）が総炭素排出の96.82%を占めることを示した。組込炭素は414.73 kg CO₂e/m²で国際基準を下回る。設計段階のデータ制約から輸送・維持段階を除外しており、結果は保守的推定である。熱帯商業建築における運用効率の優先とLCAの早期統合を提言する。

English

This study conducts a whole-building LCA of a proposed large-scale commercial mall in the Philippines, finding that operational energy (B6) dominates total carbon emissions at 96.82%, reflecting the fossil-fuel-dependent grid. Embodied carbon is 414.73 kg CO₂e/m², below international benchmarks. Excluding transport and maintenance due to data limits, results are conservative. It emphasizes prioritizing operational efficiency and integrating LCA early in design for tropical commercial buildings.

📄 Abstract（原文）

This study presents a whole-building Life Cycle Assessment (LCA) of a proposed large-scale commercial mall in a tropical emerging-economy context, addressing the limited application of LCA in the Philippine construction sector. Using One Click LCA software, the environmental impacts of the proposed Alturas Mall in Ubay, Bohol, were assessed across selected life-cycle stages. Results indicate that operational energy use (B6) dominates total life-cycle carbon emissions, accounting for 96.82% of total CO₂e, reflecting the fossil-fuel-dependent electricity mix of the Philippines. The calculated embodied carbon was 414.73 kg CO₂e/m², which falls below international benchmark thresholds. This study contributes empirical whole-building LCA evidence for large-scale commercial buildings in tropical emerging economies, a context that remains underrepresented in current literature. Transportation (A4) and selected maintenance stages (B1–B5) were excluded due to data limitations at the design stage, and embodied carbon results should therefore be interpreted as conservative estimates, particularly in archipelagic contexts such as the Philippines. The findings highlight the critical need to prioritize operational energy efficiency alongside material optimization in tropical commercial buildings and support the early integration of LCA into architectural decision-making.
