本研究旨在探討建築設計對人體「促進健康」之誘導作用，補足當前健康建築評估多為「維持健康」之指標，對提升日常身體活動面向之不足。本研究建構一套兼具理論與建築設計實務可操作性之評估架構，提出「建築誘導係數模型（Architectural Induction Factor, AIF）」，界定建築空間中「身體活動誘導程度」，建構提升日常身體活動之建築設計評估架構，達到促進健康之目的。第一階段採系統性文獻回顧及歸納演繹法，從環境知覺、空間句法、行為生態及支持性設計等權威之理論中，萃取三大構面—空間知覺性、動線便利性與功能分區使用性，依此細分六項子構面。第二階段施行層級分析法，邀建築、都市計畫、運動科學與環境衛生等跨領域專家進行矩陣比較，檢驗構面間之相對重要性及模型效度。結果顯示，三大構面之權重為空間知覺性0.364、動線便利性0.362及功能分區使用性0.274，其中動線設計順暢度（0.2646），突顯「動線設計」為提升建築誘導效果之關鍵要素；其次為「視覺可導性」及「空間辨識性」權重相同（0.1783），顯示空間直覺且清晰呈現活動誘導同樣重要，對促發日常身體活動具顯著驅動效應，進一步揭示動線直覺性、視覺可導性與空間辨識性，為驅動行為改變之首要關鍵因素，為住宅及公共空間設計提供明確可行之健康促進指引。

This study investigates how architectural design can actively promote health—a dimension often overlooked by existing healthy building assessment tools that primarily focus on maintaining health rather than enhancing daily physical activity. We therefore develop the Architectural Induction Factor (AIF) model—a theoretically rigorous yet practically operable framework—to quantify how built environments promote physical activity. In Phase I, a systematic literature review and an inductive–deductive synthesis of authoritative theories in environmental perception, space syntax, behavioral ecology, and supportive design yielded three principal dimensions (Spatial Perception Induction, Circulation Convenience, Functional Area Affordance) further delineated into six subdimensions. In Phase II, we administered an Analytic Hierarchy Process (AHP) questionnaire to fifteen interdisciplinary experts; twelve valid matrices (CR < 0.1) were analyzed to determine dimension weights: Spatial Perception Induction (0.364), Circulation Convenience (0.362), and Functional Area Affordance (0.274). Circulation Smoothness (CCI-2, 0.2646) emerged as the most critical subdimension, followed by Visual Guidability (SPI-1, 0.1783) and Spatial Recognizability (SPI-2, 0.1783), underscoring the importance of intuitive circulation and clear spatial cues in driving stair use and walking behaviors. Based on these insights, we propose a three-stage design strategy—Trigger, Connect, Stimulate—to guide the creation of residential and public spaces that systematically foster daily physical activity. The AIF model thus offers an evidence-based tool for optimizing spatial configurations to enhance occupant health and overall quality of life.
