適応型不透明外皮技術ZERAFについて、LCA・LCC・循環性指標を用い50年間で評価した報告書。新築・深改修で暖房需要を最大88%、冷房需要を最大50%、運用炭素を最大19%削減。一方でembodied影響と投資コストが高く、材料構成の最適化でembodied炭素58%・コスト75%削減の余地を示す。
English
This report presents a 50-year life-cycle assessment and costing of ZERAF, an adaptive opaque façade technology. In new-build and deep-retrofit scenarios it cuts heating demand by up to 88%, cooling by 50%, and operational carbon by 19%, with strong circularity. Higher embodied impacts and costs currently limit whole-life performance, but alternative materials could cut embodied carbon by 58% and cost by 75%.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建築物省エネ法・ZEH/ZEB政策や住宅・建築物のLCA義務化議論と親和的。外皮技術のライフサイクル炭素・コスト評価手法は、国内の建築脱炭素・Scope3カテゴリの建材調達を検討する実務者に参考となる。
In the global GX context
Aligns with global building-decarbonization and whole-life carbon disclosure trends (EU EPBD, embodied carbon reporting). Offers a replicable LCA/LCC framework for façade technologies that can inform CSRD/ISSB building-sector disclosures and green building certification.

📄 Abstract（原文）
This report presents the life-cycle environmental and economic assessment of ZERAF, an adaptive opaque façade technology designed to reduce building energy demand through dynamic thermal modulation of the building envelope. A methodological framework is developed to compare ZERAF with conventional façade and building-system solutions using Life Cycle Assessment (LCA), Life Cycle Costing (LCC), circularity metrics and building-performance indicators over a 50-year period. The study evaluates complete building-level intervention packages for new construction, deep retrofit and minor retrofit scenarios across seven representative European climates. Results for the single-family-house archetype show that ZERAF consistently achieves the lowest operational carbon emissions among new-construction and deep-retrofit solutions, reducing heating demand by up to 88%, cooling demand by up to 50%, and operational carbon emissions by up to 19%. ZERAF also demonstrates strong circularity performance. While higher embodied impacts and investment costs currently limit whole-life environmental and economic performance, alternative material configurations indicate substantial improvement potential, with embodied carbon reductions of up to 58% and embodied cost reductions of up to 75%. Overall, the results confirm the effectiveness of ZERAF's adaptive principle and identify key directions for further optimisation.
