Benefiting from natural daylight in the historic houses of Kashan played a central role in shaping their architectural form, particularly the development of central courtyards. A key parameter for evaluating the effectiveness of these courtyards in channeling daylight into adjacent spaces is (DF). Since DF is influenced by multiple variables, including the reflective properties of courtyard surfaces, it is essential to investigate the contribution of water pools and garden plots fundamental components of courtyard design to the distribution of daylight within surrounding spaces.
This study employs a quantitative and descriptive research approach, combining archival analysis with field observations, to assess the daylighting performance of water pools and garden plots in selected Qajar-era houses of Kashan. Field surveys revealed that courtyard floors are generally composed of brick, water pools, and garden plots, with the relative extent of each element varying across the studied cases. To evaluate the relationship between this variation and daylight performance, the Sectional Area Ratio (SAR) was applied to indicate courtyard daylighting efficiency. The results were then compared with the combined surface area of garden plots and water pools relative to the total courtyard area.
The findings indicate that in houses where SAR values fall below the recommended threshold, the proportion of water pool and garden plot coverage relative to the overall courtyard area increases, and vice versa. This suggests that the spatial extent of garden plots and water pools within courtyard floors contributes significantly to improving daylight availability in adjacent interior spaces, primarily by enhancing light reflection.
