本論文は、エクアドル・アンデス山間部のキチュワ・サラグーロ共同体における在来建築（バハレケ）の生気候性能を、48指標による多基準評価フレームワークで定量化した。全5つの形態タイプで生気候性能指数（BPI）が75%超、特にC型は88.5%を達成し、高熱容量の外壁と局所材料利用による低炭素性が確認された。未校正のエネルギーシミュレーションでもASHRAE快適範囲内の室温を示し、高地での持続可能な住宅政策への示唆を提供する。
English
This study systematically documents and assesses the bioclimatic performance of vernacular bahareque dwellings in the Ecuadorian Andes using a multi-criteria framework of 48 indicators. Five typologies were identified, all achieving over 75% on the Bioclimatic Performance Index (BPI), with typology C reaching 88.5%. Uncalibrated energy simulation indicated thermal comfort within ASHRAE 55-2013 ranges, highlighting the potential of high-thermal-mass, locally sourced construction for low-carbon rural housing.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では気候風土に根ざした伝統建築（民家・町家など）の再評価が進むが、本論文は国際的に未報告の高地アンデス在来工法に定量的評価を加えた点で参考になる。日本の寒冷地・山間部の低炭素住宅政策に、熱容量と地域材料活用の観点から示唆を与えうる。
In the global GX context
While most vernacular sustainability literature focuses on temperate or tropical regions, this paper provides rigorous bioclimatic documentation from a high-altitude Andean context. It demonstrates how indigenous construction systems achieve low-carbon performance through thermal mass and local materials, offering transferable insights for climate-responsive building policy in mountainous regions globally.

📄 Abstract（原文）
The construction sector accounts for approximately 36% of global final energy consumption and close to 40% of total CO2 emissions, making it a primary target of international climate policy. Despite this growing attention, the indigenous building traditions of the Ecuadorian Andes remain virtually absent from the international scientific literature on vernacular sustainability. This study presents a systematic field documentation and bioclimatic assessment of vernacular bahareque dwellings in the Kichwa-Saraguro community of Ilincho, canton of Saraguro, province of Loja, Ecuador (2700 m a.s.l.). A field survey of 30 dwellings identified five morphological typologies—I-1P, I-2P, 2B, L, and C—with typology C, a compact C-shaped block with a three-sided portal, accounting for 53.3% of the sample. A structured multi-criteria framework of 48 bioclimatic indicators distributed across eight categories, adapted to the cold-temperate mountain climate of the study area, was applied to quantify each typology’s bioclimatic performance. All typologies exceeded 75% overall compliance on the global Bioclimatic Performance Index (BPI), with typology C achieving the highest value (88.5%). Categories F (Materials and construction) and H (Cultural and social aspects) scored 100% across all typologies, reflecting system-level properties of the bahareque constructive system rather than morphological differences between typological variants; a supplementary morphological BPI restricted to Categories A–E and G is reported. An exploratory, uncalibrated energy simulation of typology C provided indicative evidence consistent with the expected thermal behavior of a high-thermal-mass bahareque envelope, with simulated minimum temperatures in the sleeping area within the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 55-2013 comfort range (T-min 18.80 °C). Collectively, these findings contribute quantified bioclimatic documentation of vernacular bahareque architecture in Ilincho, identifying attributes—encompassing solar control, spatial compactness, high-thermal-mass envelope performance, and use of locally sourced low-embodied-energy materials—that may inform sustainable rural housing discussions in the Ecuadorian Andes and comparable high-altitude mountain contexts. Its documentation in the indexed scientific literature constitutes a step toward recognizing this constructive heritage as a practical resource for low-carbon building policy.
