トルコの6気候区の省を対象に、CLT壁構法8種のエネルギー消費・炭素排出・凝縮リスク・初期投資コストを動的シミュレーションとLCAで比較した研究。XPS断熱はロックウール比でエネルギー消費を約4%、5層CLTは3層比で約6%削減できることを示す。多基準正規化により気候適応型の壁構法選択を支援する。
English
This study evaluates eight cross-laminated timber wall assemblies across six Turkish climate zones using dynamic energy simulation, LCA and cost analysis. XPS insulation cut energy use ~4% versus rock wool, and 5-layer CLT cut energy use ~6% versus 3-layer. A min–max multicriteria approach supports climate-adaptive envelope selection balancing energy, carbon and cost.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
木造・CLT建築の炭素貯蔵と省エネ性能を定量化する手法は、日本でも進む非住宅木造化・ZEH政策や建材の炭素評価に関連する。ただし評価枠組みはトルコの気候区・規格に依存する。
In the global GX context
Adds empirical evidence on embodied and operational carbon trade-offs in mass-timber envelopes, relevant to global whole-building LCA and green building certification discussions, though framed within Turkish climate zones and standards.

📄 Abstract（原文）
To mitigate building-related environmental impacts, it is crucial to evaluate the performance of innovative materials such as cross-laminated timber (CLT), which is increasingly adopted worldwide and noted for its negative carbon footprint, particularly in terms of energy and cost efficiency. Across six pilot provinces representing distinct climate zones in Türkiye, a holistic evaluation was conducted of the energy and carbon emissions performance, condensation risk analysis, and associated initial investment costs of eight CLT building envelope configurations commonly used in residential construction within the global wood industry. This evaluation was carried out using dynamic building energy simulation (DesignBuilder), One Click LCA, and IZODER TS 825 software. The scenarios’ performance was assessed by comparing total energy consumption, carbon emissions, and cost, which were scaled using the min–max normalisation method. Among the eight proposed CLT wall configurations, wall assemblies using extruded polystyrene (XPS) showed a 4% reduction in energy consumption compared with rock wool alternatives in all selected provinces. Additionally, wall configurations employing 5-layer CLT exhibited a 6% decrease in energy consumption compared to those that utilised 3-layer CLT wall alternatives.
