NatureNest: Enhancing Green Roof Performance in Disaster-Prone Areas by Studying Slope Effects on Wind Speed Endurance and Water Flow's Structural Impact Performance

In disaster-prone areas like San Pablo, Laguna, where typhoons and heavy rainfall pose significant threats, ensuring the structural integrity of roofs is crucial to minimizing damage and improving resilience. This study examines the relationship between roof slope and structural integrity, focusing on minimum and maximum wind speed endurance and water flow impact at 10°, 30°, and 45° slopes. Using a quantitative approach, prototypes were designed and tested using Solid Works 2023 to simulate and assess their performance under varying wind speeds and water flow conditions, aiming to identify the best roof slop for withstanding extreme weather conditions. Results indicate that both standard and green roofs offer the best wind resistance at a 45° slope at the lowest maximum wind speed of (2079.64 km/h, Y-axis) and minimized vertical wind forces, ranging from 186.82 to 1187.25 km/h along the Z-axis. On the other hand, a 30° slope minimizes structural stress caused by water flow impact (2.82 km/h along the Z-axis; 565.29 km/h along the X-axis), reducing pooling and erosion. The 30° slope managed flow more efficiently, reaching a peak of 3541.29 km/h along the X-axis.These findings provide valuable insights that can significantly contribute to the development of structurally efficient and resilient housing. To enhance the accuracy, applicability, and overall comprehensiveness of this study, researchers recommend integrating real-world testing in areas that experience various environmental conditions. Additionally, further exploration of alternative lightweight materials is suggested to improve structural feasibility and ensure that the green roof design can be simulated as a whole rather than assessing it in separate layers.
