Abstract

Optimization of Spatial Configuration to Improve Natural Lighting in Single-Aspect Units at Rusun Putri Cempo, Surakarta

Urban population growth has driven the construction of low-income public housing as a vertical housing solution. However, the commonly applied double-loaded corridor typology restricts units to a single-aspect condition, limiting natural light entry to only one façade. This study aims to evaluate the influence of spatial configuration on daylighting performance in Rusun Putri Cempo Blok E Surakarta using DIALux Evo 13.2 with data collection based on existing building geometry. The evaluation measures the Daylight Factor (DF) and daily illuminance distribution. Baseline evaluation results show that despite achieving a 17% Window-to-Wall Ratio (WWR), the living room only obtains a 0,03% DF due to obstruction by the solid bedroom walls. Of the two reconfiguration scenarios tested, Design Configuration 2 proved the most effective, increasing the living room’s DF to 2,87–2,89% and ensuring all rooms meet the SNI 03-6575-2001 standards.
