Nowadays, the development of modern architecture has led to a more favorable attitude in reconstructing and repairing abandoned and destroyed historic buildings in Iran. Regeneration of these buildings using modern construction methods, which are fit to Iranian architectural patterns, is one of the best ways to restore their forgotten values. On the other hand, since natural light is the just light source for architects, improving the quality of natural light emission inside this building by technical methods was considered as the main objective of providing the design strategy in this study. Evidence has been shown that the quality of light emitted indoors via hornos is the principal challenge related to the Safa Bath. Accordingly, light conditions were simulated in the present study using Ladybug, Honeybee, and DesignBuilder software. Then, the required lights were directed inside this building to improve the quality of their diffusion using optical fibers and the HSL solar system placed on the dome. Results revealed that the implementation of the proposed idea improved lighting situations by about 40% in summer to 80% in winter and about 42% in municipal electricity consumption. It should be noted that the obtained plans and diagrams were qualitatively analyzed and assessed at the end of the research.
