ナイジェリア・ブワリ地区の居住者127名を対象に、安定化土ブロック(SEB)・圧縮土ブロック(CEB)・ラテライトブロックの熱性能と受容性を調査。80.3%が高い認知度と居住意欲を示し、土壁の熱性能を「満足以上」と評価。一方83.5%が現行のセメントブロック住宅で機械冷却に頻繁に依存。社会的スティグマが主要障壁であり、気候対応型住宅への土材料再導入と職人育成の政策的示唆を提示する。
English
Survey of 127 residents in Bwari, Nigeria, on thermal performance and acceptance of stabilized earth blocks, compressed earth blocks, and laterite blocks. 80.3% showed high awareness and willingness to live in earth-walled housing, rating their thermal performance satisfactory or better, while 83.5% rely on mechanical cooling in current cement-block homes. Social stigma is the main barrier; findings support reintegrating improved earth materials into climate-responsive housing.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では直接の接点は薄いが、低炭素建材(セメント代替)とパッシブ設計による運用エネルギー削減は、建設分野のScope 3削減・省エネ建築政策に関連する。地方建材の普及と職人育成の議論は、地域循環型の脱炭素建築を検討する日本企業・自治体にも示唆を与える。
In the global GX context
This study adds Global South empirical evidence on embodied-carbon reduction and passive cooling in residential construction, complementing global decarbonization scholarship on low-carbon building materials. It speaks to the buildings sector's role in national climate plans and to just-transition concerns around local material supply chains and artisan capacity, though it does not engage TCFD/ISSB disclosure frameworks directly.
👥 読者別の含意
🔬研究者:低炭素建材の受容性と熱性能の主観評価に関するGlobal Southの実証データとして、建築脱炭素研究に有用。
🏢実務担当者:セメント代替の土系建材とパッシブ設計の組み合わせが、暑熱地域の住宅コストと快適性に寄与しうる点を参考にできる。
🏛政策担当者:地方建材の普及促進と職人育成、社会的スティグマ解消に向けた政策設計の根拠を提供する。
📄 Abstract（原文）
The dominance of cement-sandcrete walling systems in contemporary Nigerian residential construction has produced buildings with high embodied carbon and inadequate passive thermal regulation in hot-humid climates. This study investigates the thermal performance perceptions and community acceptance of improved earth-based walling materials specifically stabilized earth blocks (SEBs), compressed earth blocks (CEBs) and laterite blocks among residents of Bwari Area Council, Federal Capital Territory, Nigeria. A mixed-methods survey of 127 valid respondents was analyzed using descriptive statistics, Likert-scale mean scores and thematic coding. Results indicate high awareness (80.3 %) and strong willingness to reside in earth-walled housing (mean = 4.35/5). Respondents rated the comparative thermal performance of earth/laterite walls versus cement blocks as satisfactory or very satisfactory (80.3 %), while 83.5 % reported frequent reliance on mechanical cooling in their current cement-block dwellings. Preference for stabilized earth or hybrid earth-modern systems reached 80.3 %. Social stigma remains the principal barrier. The findings provide empirical validation for the reintegration of improved earth materials as primary walling systems in climate-responsive housing and inform design strategies that combine high thermal mass, passive cooling features and contemporary aesthetic finishes. Policy implications for local material promotion and artisan capacity building are discussed.
