Grasshopper上でパラメトリック設計、サロゲート支援最適化、実測キャリブレーション、LCA・コスト評価を統合するCAMEワークフローを提案。ドバイの実大塩レンガパビリオンで実証し、塩空洞の平均作用温度は参照コンクリート壁より3.1℃低く、位相遅れ6.3時間を観測。スクリーニングLCAでは体化炭素が69.7%削減（±50%感度でも62.3%以上）と示した。
English
Presents the CAME workflow integrating parametric design, surrogate-assisted NSGA-II optimisation, field monitoring and calibrated EnergyPlus simulation with screening LCA and costing. A full-scale Himalayan salt-brick pavilion in Dubai showed mean operative temperature 3.1°C below a concrete reference with a 6.3-h phase shift, and 69.7% lower embodied carbon (≥62.3% under ±50% sensitivity). Evidence-status classifications are explicitly assigned.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
建築物の体化炭素削減はScope 3カテゴリ1・2やSSBJのサプライチェーン排出把握と直結する論点。日本でもZEB・木造化・低炭素建材選定の初期設計判断に応用可能な手法として参考になる。
In the global GX context
Embodied-carbon screening at early design stages feeds directly into Scope 3 category 1/2 accounting and building-sector disclosure under ISSB/CSRD. The workflow's explicit evidence-status labelling is a useful model for how disclosure-ready data quality can be flagged in LCA-based claims.

📄 Abstract（原文）
Purpose This study pilot-demonstrates the Climate-Adaptive Mineral Envelope (CAME) workflow, integrating fragmented analytical tools within Grasshopper to support low-carbon envelope decisions for hot-arid construction.Design/methodology/approach A discretised Schwarz P envelope underwent structural verification and NSGA-II optimisation using a Gaussian-process surrogate trained on 120 EnergyPlus simulations. A Pareto-knee configuration was built as a 3,000-brick Himalayan salt pavilion exhibited at Dubai Design Week 2024. Nine-day monitoring of operative and surface temperatures and relative humidity informed calibration of an EnergyPlus model using the Effective Moisture Penetration Depth algorithm. Screening life-cycle assessment (LCA) and costing completed the work flow.Findings Surrogate RMSE was 0.38 °C under leave-one-out cross-validation and 0.42 °C across six out-of-sample simulations. Calibrated model RMSE was 1.06–1.31 °C, with CV(RMSE) of 3.4–3.6%. NMBE was not calculated, precluding full ASHRAE Guideline 14 compliance claims. Mean operative temperature in the salt cavity was 3.1 °C below the concrete-masonry-unit reference, with a 6.3-h phase shift and 0.43 decrement factor. These contrasts are descriptive because observations were serially correlated, monitoring covered one pavilion and one panel, and cavity-node convective exposure was unquantified. Screening LCA indicated 69.7% lower embodied carbon, remaining ≥62.3% across a ±50% sensitivity band.Originality/value The workflow connects parametric design, surrogate-assisted optimisation, fabrication, monitoring and calibrated simulation with carbon and cost screening, assigning explicit evidence-status classifications.Practical implications Comparative thermal, carbon and cost screening is delivered within one working session. Permanent salt-envelope application requires binder redesign, deliquescence-resistant detailing and code-compliance evidence.
