Light plays a fundamental role in shaping spatial experience within traditional Iranian courtyard houses. While previous studies have largely examined light through symbolic, climatic, or technical perspectives, less attention has been given to how light organizes movement, hierarchy, privacy, and environmental regulation within the house itself.

The study adopts a qualitative and diagram-based methodology combining literature review, architectural analysis, and comparative synthesis. Four case studies, Tabatabaei House, Lariha House, Mollabashi House, and Pirnia House, are examined to identify recurring mechanisms through which light structures movement, hierarchy, privacy, and environmental performance. The analysis focuses on courtyard organization, threshold sequences, spatial depth, material filtering systems, reflected illumination, and sectional variation. The findings reveal how recurring light transitions develop into identifiable spatial patterns across the selected houses. Four primary modes of light organization were identified: sequential light transition, distributed courtyard illumination, material-based filtering systems, and tectonic light structuring. Across the selected houses, light is shown to operate through coordinated relationships between courtyards, thresholds, enclosure depth, reflective surfaces, and filtering elements rather than through isolated architectural devices. These mechanisms transform intense exterior solar exposure into differentiated luminous environments that support environmental moderation, perceptual adaptation, and spatial hierarchy. Rather than treating light as a visual phenomenon alone, the research demonstrates how light functions as a system of spatial organization and environmental regulation. The identified patterns provide a framework for understanding and reinterpreting traditional environmental intelligence within contemporary architectural design.
La luce svolge un ruolo fondamentale nella definizione dell’esperienza spaziale nelle tradizionali case iraniane a corte. Sebbene gli studi precedenti abbiano esaminato la luce principalmente da prospettive simboliche, climatiche o tecniche, minore attenzione è stata dedicata al modo in cui essa organizza il movimento, la gerarchia spaziale, la privacy e la regolazione ambientale all’interno dell’abitazione. Questa ricerca analizza il modo in cui la luce viene regolata, attenuata, filtrata e ridistribuita attraverso la forma architettonica nelle tradizionali case iraniane a corte. Lo studio adotta una metodologia qualitativa basata su diagrammi che combina revisione della letteratura, analisi architettonica e sintesi comparativa. Quattro casi studio, la Casa Tabatabaei, la Casa Lariha, la Casa Mollabashi e la Casa Pirnia, vengono esaminati per identificare i meccanismi ricorrenti attraverso i quali la luce struttura il movimento, la gerarchia, la privacy e le prestazioni ambientali. L’analisi si concentra sull’organizzazione della corte, sulle sequenze di soglia, sulla profondità spaziale, sui sistemi di filtraggio materico, sull’illuminazione riflessa e sulla variazione sezionale. I risultati mostrano come ricorrenti transizioni luminose si sviluppino in pattern spaziali riconoscibili nei diversi casi studio. Sono state identificate quattro principali modalità di organizzazione della luce: la transizione luminosa sequenziale, l’illuminazione distribuita della corte, i sistemi di filtraggio basati sui materiali e la strutturazione tettonica della luce. Nei casi analizzati, la luce opera attraverso relazioni coordinate tra corti, soglie, profondità dell’involucro, superfici riflettenti ed elementi filtranti, piuttosto che tramite singoli dispositivi architettonici isolati. Questi meccanismi trasformano l’intensa esposizione solare esterna in ambienti luminosi differenziati che favoriscono la moderazione ambientale, l’adattamento percettivo e la gerarchia spaziale. Piuttosto che essere considerata esclusivamente come un fenomeno visivo, la ricerca dimostra come la luce funzioni come un sistema di organizzazione spaziale e di regolazione ambientale. I pattern individuati offrono un quadro interpretativo per comprendere e reinterpretare l’intelligenza ambientale tradizionale all’interno della progettazione architettonica contemporanea.

Abstract
Light plays a fundamental role in shaping spatial experience within traditional Iranian courtyard houses. While previous studies have largely examined light through symbolic, climatic, or technical perspectives, less attention has been given to how light organizes movement, hierarchy, privacy, and environmental regulation within the house itself. This research investigates how light is regulated, attenuated, filtered, and redistributed through architectural form in traditional Iranian courtyard houses. The study adopts a qualitative and diagram-based methodology combining literature review, architectural analysis, and comparative synthesis. Four case studies, Tabatabaei House, Lariha House, Mollabashi House, and Pirnia House, are examined to identify recurring mechanisms through which light structures movement, hierarchy, privacy, and environmental performance. The analysis focuses on courtyard organization, threshold sequences, spatial depth, material filtering systems, reflected illumination, and sectional variation. The findings reveal how recurring light transitions develop into identifiable spatial patterns across the selected houses. Four primary modes of light organization were identified: sequential light transition, distributed courtyard illumination, material-based filtering systems, and tectonic light structuring. Across the selected houses, light is shown to operate through coordinated relationships between courtyards, thresholds, enclosure depth, reflective surfaces, and filtering elements rather than through isolated architectural devices. These mechanisms transform intense exterior solar exposure into differentiated luminous environments that support environmental moderation, perceptual adaptation, and spatial hierarchy. Rather than treating light as a visual phenomenon alone, the research demonstrates how light functions as a system of spatial organization and environmental regulation. The identified patterns provide a framework for understanding and reinterpreting traditional environmental intelligence within contemporary architectural design.| File | Dimensione | Formato | |
