Journal of Measurements in Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 2, 2025

This study aims to address the growing urban heat challenges by exploring application of AI-driven simulations improve outdoor thermal comfort and air quality in parks. The primary goal was optimize park designs using advanced AI technologies data analysis, improving public green spaces. A highly accurate model employed, with performance metrics including RMSE (3.68 °C), MAPE (6.50 %), a Pearson Correlation Coefficient 0.982, evaluate key environmental parameters such as temperature, wind speed, radiation. These assessments served foundation for design optimization through integration Computational Fluid Dynamics (CFD) modeling. Innovative improvements, enhanced shading structures, strategic vegetation placement, refined material selection, resulted 15 % reduction radiation, 1 m/s increase decrease PM 2.5 10 concentrations 12 %, respectively. changes led increased pedestrian comfort, improved health outcomes, 20 rise usage. Post-optimization analysis further demonstrated 25 radiation improvement Air Quality Index (AQI). Furthermore, resilience testing short-term climate indicated that these improvements would remain effective at least three years, confirming robustness long-term sustainability AI-enhanced strategies. research highlights potential integrating design, offering valuable insights into creating sustainable, user-centered By combining real-world optimization, emphasizes importance interdisciplinary approaches enhancing livability environments.

A novel reflective material coated polyurethane resin-based porous composite paving material for mitigating urban heat island effect

Transactions of the IMF, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 9

Published: Jan. 3, 2025

Increasing urban temperatures due to the heat island effect and global warming have become a significant concern around world. As areas grow, they often replace naturally permeable materials with impermeable ones, contributing effect, raising by 1 3°C annually. This study proposes solution in form of novel resin-based composite paving material that is permeable, reflects sunlight, maintains flexural strength. The consists natural stone aggregate, recycled plastic, rubber, polyurethane resin. Testing revealed flexure strength range 2.46–2.8 MPa suitable for moderate loads. Optimal proportions featured equal volume percentages rubber at 0.07 g cm−3 resin offering 27% porosity aiding water drainage. analysis conducted on sample using X-ray tomography data found total 27.14%, indicating voids present within composed 26.43%, connected 0.71% isolated porosity. Anti-skid tests confirmed excellent pedestrian safety pendulum test values above 35 PTV. Coatings such as glass beads, epoxy white paste, aluminium powder were explored enhance reflectivity. Aluminium powder-coated pavement achieved highest Albedo index 0.096353, 101.7% more reflective than reference, surpassing bead paste coatings. innovative addresses concerns while enhanced reflectivity public walkways.
