Sensory Materials for the Sustainable Revitalization of Public Spaces: Development and Evaluation of Photoluminescent and Aromatic Bricks

The quality and functionality of urban public spaces are often limited by inadequate nighttime lighting, low sensory comfort, and inefficient construction waste management, reducing usability and perceived safety. This study aims to develop and evaluate sensory materials for the sustainable revitalization of public spaces through the design of photo-luminescent and aromatic bricks using recycled materials. A mixed-method experimental approach was adopted, including prototype fabrication and performance assessment through illuminance, luminance, volatile compound release, and physical property tests. The results indicate that the developed bricks achieve illuminance levels of approximately 2 lux under real conditions, within the recommended range for low-activity pedestrian areas, and exhibit moderate and sustained aromatic release with functional performance up to 0.90 m. In addition, the materials show adequate physical stability, mechanical re-sistance, and controlled water absorption. These findings suggest that the proposed mate-rials can contribute to improving nighttime visibility and sensory perception in public spaces. This study proposes an integrated approach combining material innovation and urban design, supporting the use of passive multisensory strategies for sustainable public space revitalization.
