本稿は、菌糸体、湿度応答性木材、麻の3つの天然素材が建築分野の脱炭素化とエネルギー効率改善に与える可能性をレビューする。これらの素材を従来の建築材料と比較し、それぞれの特性（熱伝導率、密度、気候影響など）を評価。菌糸体は断熱材として、麻は最も成熟した選択肢として、湿度応答性木材はパッシブアクチュエータとして有望であるが、建築レベルでの省エネ効果の定量化が必要とされる。
English
This paper critically reviews the potential of mycelium, hygromorphic wood, and hemp as emerging natural materials for low-carbon construction, comparing them with conventional materials in specific applications. It reports that mycelium composites can achieve low thermal conductivity and climate impact, hemp can have negative carbon emissions, and hygromorphic wood offers passive actuation for adaptive envelopes. The review highlights that cross-study comparisons are challenging due to varying methodologies and system boundaries.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では建築分野の脱炭素化が急務であり、本稿が扱う菌糸体や麻などの天然素材は、SSBJの建築関連スコープ3排出量削減に貢献する可能性がある。ただし、日本の気候や建築慣行に適したデータが不足しているため、さらなる実証研究が必要。
In the global GX context
This review contributes to the global discourse on low-carbon construction by synthesizing recent data on mycelium, wood, and hemp. It is relevant for ISSB-aligned reporting on embodied carbon and for practitioners seeking alternatives to conventional insulation and structural materials.

📄 Abstract（原文）
Decarbonising the building sector requires addressing both embodied carbon in materials and operational energy for indoor conditioning. This article critically reviews the potential of mycelium, hygromorphic wood and hemp as emerging natural materials for low-carbon construction, comparing them with conventional materials only within function-specific applications such as envelopes, insulation, non-load-bearing components and passive systems. Recent comparative literature shows that mycelium composites can reach thermal conductivities of 0.026–0.12 W/m·K and densities of 51–280 kg/m3; in wood–mycelium formulations, an average density of 167.5 kg/m3 and climate impact of 2.13 kg CO2-eq/kg with a conventional electricity mix, reduced to 0.66 kg CO2-eq/kg with renewable energy, have been reported. Hemp shows typical densities of 140–540 kg/m3, conductivities of 0.061–0.12 W/m·K, compressive strengths of 0.3–3.5 MPa and potentially negative climate performance of about −40 to −80 kg CO2-eq/m3, compared with +300 to +400 kg CO2-eq/m3 for conventional concrete. Hygromorphic wood is relevant not as insulation or a primary structural replacement, but as a passive actuation material for adaptive envelopes. Hemp is currently the most mature option, mycelium is promising for circular non-structural panels and insulation, and hygromorphic wood is an operational-modification strategy whose building-level energy benefits still require direct quantification. Cross-study comparisons should be interpreted as bounded ranges because composition, fabrication, testing and LCA (Life Cycle Assessment) system boundaries vary substantially across the literature.
