The advent of green construction materials has introduced innovative solutions such as light-emitting concrete, also known as translucent concrete (TC). This material integrates optical fibers within the concrete matrix, allowing natural light to penetrate structures, thereby reducing reliance on artificial lighting and enhancing energy efficiency. This study investigates the optimal ratios and organization of optical fibers, analyzing TC’s light-transmitting, mechanical, thermal, and energy-saving properties. Results indicate that a 4–5% optical fiber content achieves an ideal balance between light transmission and structural integrity, reducing energy consumption by 4.3–6%. Compression tests reveal that TC maintains comparable compressive strength to conventional concrete, confirming its suitability for practical applications. TC’s potential extends to various architectural applications, including facades, interior partitions, and decorative elements, promoting sustainable and visually appealing infrastructure. By harnessing natural light, TC contributes to energy-efficient building designs, aligning with modern green construction practices.
